The general quality of Chinese CCTV monitors gets much improved. Three major Chinese monitor manufacturers are Skyworth, Stonesonic and Satow. The industry started export quite earlier compared to other security vendors in China. Now, LCD monitors, monitors for surveillance in commercial setting and LCD multiple screen combination panel wall are their main products.

According to some industry expert, the ratio of global LCD to CRT production is roughly about 6:4. LCD monitors, in the past, had some defeats in certain aspects, such as brightness, contrast, visual angle, response time, lifespan and production. Along with the technical improvement, current LCD monitors are better performed in color, brightness, contrast, nearly 180-degree visual angle and response time. Plus, it has advantages in thin design, environmental friendly, and energy-saved (because of lead in the components of CRT monitors). LCD monitors have gradually replaced the CRT.

Many users might confuse LCD monitors with LCD display or LCD TV. However, the basic requirements for LCD monitors are quite different from them. For one LCD monitor, it is usually required to have higher standards on visual angle, brightness and contrast, color display ability, response time, resolution and the stability to operate continuously 24/7. Therefore, the safe electric performance and good heat emission design should be taken into the consideration for the design of one LCD monitor.

For one LCD monitor, a much broader visual angle and higher brightness and contrast are required for watching the fixed video picture at long distances. For PC display, the ideal pictures can be showed if it meets the required brightness and contrast of 200 cd/m2 and 300:1 respectively. But for monitors, the brightness and contrast should be not less than 300 cd/m2 and 450:1. The quality of picture is not only related to the brightness and contrast but also the definition, color reducibility, and SNR (signal to noise ratio) specifications. In addition, the response time is also quite important for LCD monitors. Manufacturers recently have taken a lot of efforts on increasing the response speed from the early 60 ms, 30 ms and 25 ms to current 16 ms, 12 ms and 8 ms; the tailing phenomenon has been almost disappeared and has little difference with response time for CRT.

One of Satow"s latest launch--42" Color LCD monitor, ML-4200TM1. It features 3-dimension image processing to reduce the noise and avoid the interference from the bright, making the picture display more sophisticated with PAL/NTSC. Its unique DNX technology makes the image more stable while displaying the moving pictures and video. The resolution is about 1920 x 1080; brightness is 500 cd/m2 and the contrast ratio is 2000:1. The response time can be 6.5 ms. Power supply is AC 100-240V.

Many LCD display"s power is often DC 12 V, using the external AC power adapter 220V AC/12V DC; however, it could not meet the requirements of electromagnetism interference (EMI) and electromagnetism compatible electron agnetic compatibility (E-MC) for professional monitors working at factories. Take Stonesonic. It adopted the reliable built-in switch power instead that can meet the requirements of electromagnetism compatible and interference standard. So it ensures the constant working of the machine no matter under what kind of environments and its much more coordinated appear once design is also more convenient for project mounting and operation. Skyworth also highlights its internal power supply with low consumption, and its screen service expectancy exceeds 60,000 hours. The latest I2C controlling circuits, the high reliability of whole system.

The luminescence of LCD panel is realized through several lamp tubes (cathode vacuum tube). Because some of the tubers are fixed at the fringe of the panel, it is normal that the frame becomes heated when being used for a certain period. In the design of LCD monitors, Stonesonic applied the hydrodynamics theory to make the air whirlpool inside the space of the machine form the convection, and operate the heat emission through those metal parts inside at the same time, which all ensure the reliable and constant working of the machine. So it will not affect the lifespan of the monitor if the frame of the LCD feels a little heated by hand.

Stonesonic recently launched one 19"color LCD monitor built-in DVR--SCM-1980MR. It is one kind of 8-channel monitoring and recording all-in-one monitor, adopting top-quality 19" TFT LCD panel and has functions of 4-8 channels composite video simultaneous input, real-time monitoring and recording, network remote monitoring, recording backup and alarm pan/tilt controlling.

Satow Eletronic also has one 17" LCD with built-in 4-channel MPEG-4 DVR system-BL-1700T4/CP-5714CB. Adopting the latest DSP hardware compression for each channel, the resolution is quite high. It can remote monitor via network, viewing with IE Browser or client-end software. For the LCD monitor, its contrast ratio is 800:1, brightness ratio of 300 cd/m2, display color in 16.2 M.

Stonesonic and Skywor th also developed their latest products of LCD combination panel wall. For Stonesonic, its LCD combination panel wall has already been registered and approved for six patents. The hardware basic is FPG A array, using parallel high speed image processing technology. It implements multiple high speed video signal"s unify processing technology. It totally replaces the insert card combination controller and solves the problem of quantity limitation of VGA input. It possesses all the excellent DID display technology, embedded hardware combination technology, multiple image processing technology, signal switching technology. This advanced LCD combination panel wall display system has benefits of high brightness and high definition, low power consumption and long lifespan.

Stonesonic monitor is used in many different applications such as security, broadcast, industry and multi-media. Their application in security accounts for 60 to 70 percent. Its strengths are high definition in image quality; more natural color in display. Its LCD export accounts for 50 percent of their total market. Till now, Stonesonic has had sales points in over 80 countries. It targets more at European and US markets. The latest products also includes one big IP screen monitor; very easy to install within one single IP cable. It also differentiated others in self-developed chipsets for monitors. Other vendors might adopt AV chips for LCD monitor so the 3D image may be worse in quality.

A digital camera is a camera that captures photographs in digital memory. Most cameras produced today are digital,photographic film. Digital cameras are now widely incorporated into mobile devices like smartphones with the same or more capabilities and features of dedicated cameras (which are still available).

Digital and digital movie cameras share an optical system, typically using a lens with a variable diaphragm to focus light onto an image pickup device.shutter admit a controlled amount of light to the image, just as with film, but the image pickup device is electronic rather than chemical. However, unlike film cameras, digital cameras can display images on a screen immediately after being recorded, and store and delete images from memory. Many digital cameras can also record moving videos with sound. Some digital cameras can crop and stitch pictures and perform other elementary image editing.

In the 1960s, Eugene F. Lally of the Jet Propulsion Laboratory was thinking about how to use a mosaic photosensor to capture digital images. His idea was to take pictures of the planets and stars while travelling through space to give information about the astronauts" position.Texas Instruments employee Willis Adcock"s film-less camera (US patent 4,057,830) in 1972,

The Cromemco Cyclops was an all-digital camera introduced as a commercial product in 1975. Its design was published as a hobbyist construction project in the February 1975 issue of RAM (DRAM) memory chip.

Steven Sasson, an engineer at Eastman Kodak, invented and built a self-contained electronic camera that used a CCD image sensor in 1975.Fujifilm began developing CCD technology in the 1970s.

Nikon has been interested in digital photography since the mid-1980s. In 1986, while presenting to Photokina, Nikon introduced an operational prototype of the first SLR-type electronic camera (Still Video Camera), manufactured by Panasonic.pixels. Storage media, a magnetic floppy disk inside the camera allows recording 25 or 50 B&W images, depending on the definition.

At Photokina 1988, Fujifilm introduced the FUJIX DS-1P, the first fully digital camera, capable of saving data to a semiconductor memory card. The camera"s memory card had a capacity of 2 MB of SRAM (static random-access memory), and could hold up to ten photographs. In 1989, Fujifilm released the FUJIX DS-X, the first fully digital camera to be commercially released.Toshiba"s 40 MB flash memory card was adopted for several digital cameras.

The first commercial camera phone was the Kyocera Visual Phone VP-210, released in Japan in May 1999.pixel front-facing camera.digital images, which could be sent over e-mail, or the phone could send up to two images per second over Japan"s Personal Handy-phone System (PHS) cellular network.Samsung SCH-V200, released in South Korea in June 2000, was also one of the first phones with a built-in camera. It had a TFT liquid-crystal display (LCD) and stored up to 20 digital photos at 350,000-pixel resolution. However, it could not send the resulting image over the telephone function, but required a computer connection to access photos.J-SH04, a Sharp J-Phone model sold in Japan in November 2000.cell phones had an integrated digital camera and by the early 2010s, almost all smartphones had an integrated digital camera.

The two major types of digital image sensor are CCD and CMOS. A CCD sensor has one amplifier for all the pixels, while each pixel in a CMOS active-pixel sensor has its own amplifier.back-side-illuminated CMOS (BSI-CMOS) sensor. The image processing capabilities of the camera determine the outcome of the final image quality much more than the sensor type.

The resolution of a digital camera is often limited by the image sensor that turns light into discrete signals. The brighter the image at a given point on the sensor, the larger the value that is read for that pixel.

Depending on the physical structure of the sensor, a color filter array may be used, which requires demosaicing to recreate a full-color image. The number of pixels in the sensor determines the camera"s "pixel count".

An image sharpness is presented through the crisp detail, defined lines, and its depicted contrast. Sharpness is a factor of multiple systems throughout the DSLR camera by its ISO, resolution, lens and the lens settings, the environment of the image and its post processing. Images have a possibility of being too sharp but it can never be too in focus.

A digital camera resolution is determined by a digital sensor. The digital sensor indicates a high level of sharpness can be produced through the amount of noise and grain that is tolerated through the lens of the camera. Resolution within the field of digital still and digital movie is indicated through the camera"s ability to determine detail based on the distance which is then measured by frame size, pixel type, number, and organization although some DSLR cameras have resolutions limited it almost impossible to not have the proper sharpness for an image. The ISO choice when taking a photo effects the quality of the image as high ISO settings equates to an image that is less sharp due to increased amount of noise allowed into the image along with too little noise can also produce an image that is not sharp.

Single-shot capture systems use either one sensor chip with a Bayer filter mosaic, or three separate image sensors (one each for the primary additive colors red, green, and blue) which are exposed to the same image via a beam splitter (see Three-CCD camera).

The third method is called scanning because the sensor moves across the focal plane much like the sensor of an image scanner. The linear or tri-linear sensors in scanning cameras utilize only a single line of photosensors, or three lines for the three colors. Scanning may be accomplished by moving the sensor (for example, when using color co-site sampling) or by rotating the whole camera. A digital rotating line camera offers images consisting of a total resolution that is very high.

Improvements in single-shot cameras and image file processing at the beginning of the 21st century made single shot cameras almost completely dominant, even in high-end commercial photography.

Cameras that use a beam-splitter single-shot 3CCD approach, three-filter multi-shot approach, color co-site sampling or Foveon X3 sensor do not use anti-aliasing filters, nor demosaicing.

Firmware in the camera, or a software in a raw converter program such as Adobe Camera Raw, interprets the raw data from the sensor to obtain a full color image, because the RGB color model requires three intensity values for each pixel: one each for the red, green, and blue (other color models, when used, also require three or more values per pixel).

Cameras with digital image sensors that are smaller than the typical 35 mm film size have a smaller field or angle of view when used with a lens of the same focal length. This is because angle of view is a function of both focal length and the sensor or film size used.

The crop factor is relative to the 35mm film format. If a smaller sensor is used, as in most digicams, the field of view is cropped by the sensor to smaller than the 35 mm full-frame format"s field of view. This narrowing of the field of view may be described as crop factor, a factor by which a longer focal length lens would be needed to get the same field of view on a 35 mm film camera. Full-frame digital SLRs utilize a sensor of the same size as a frame of 35 mm film.

Common values for field of view crop in DSLRs using active pixel sensors include 1.3x for some Canon (APS-H) sensors, 1.5x for Sony APS-C sensors used by Nikon, Pentax and Konica Minolta and for Fujifilm sensors, 1.6 (APS-C) for most Canon sensors, ~1.7x for Sigma"s Foveon sensors and 2x for Kodak and Panasonic 4/3-inch sensors currently used by Olympus and Panasonic. Crop factors for non-SLR consumer compact and bridge cameras are larger, frequently 4x or more.

The resolution of a digital camera is often limited by the image sensor that turns light into discrete signals. The brighter the image at a given point on the sensor, the larger the value that is read for that pixel. Depending on the physical structure of the sensor, a color filter array may be used, which requires demosaicing to recreate a full-color image. The number of pixels in the sensor determines the camera"s "pixel count". In a typical sensor, the pixel count is the product of the number of rows and the number of columns. Pixels are square and is often equal to 1, for example, a 1,000 by 1,000 pixel sensor would have 1,000,000 pixels, or 1 megapixel. On full-frame sensors (i.e., 24 mm 36 mm), some cameras propose images with 20–25 million pixels that were captured by 7.5–m photosites, or a surface that is 50 times larger.

Digital cameras come in a wide range of sizes, prices and capabilities. In addition to general purpose digital cameras, specialized cameras including multispectral imaging equipment and astrographs are used for scientific, military, medical and other special purposes.

Compact cameras are usually designed to be easy to use. Almost all include an automatic mode, or "auto mode", which automatically makes all camera settings for the user. Some also have manual controls. Compact digital cameras typically contain a small sensor which trades-off picture quality for compactness and simplicity; images can usually only be stored using lossy compression (JPEG). Most have a built-in flash usually of low power, sufficient for nearby subjects. A few high end compact digital cameras have a hotshoe for connecting to an external flash. Live preview is almost always used to frame the photo on an integrated LCD. In addition to being able to take still photographs almost all compact cameras have the ability to record video.

Compacts often have macro capability and zoom lenses, but the zoom range (up to 30x) is generally enough for candid photography but less than is available on bridge cameras (more than 60x), or the interchangeable lenses of DSLR cameras available at a much higher cost.Autofocus systems in compact digital cameras generally are based on a contrast-detection methodology using the image data from the live preview feed of the main imager. Some compact digital cameras use a hybrid autofocus system similar to what is commonly available on DSLRs.

Typically, compact digital cameras incorporate a nearly silent leaf shutter into the lens but play a simulated camera sound for skeuomorphic purposes.

For low cost and small size, these cameras typically use image sensor formats with a diagonal between 6 and 11 mm, corresponding to a crop factor between 7 and 4. This gives them weaker low-light performance, greater depth of field, generally closer focusing ability, and smaller components than cameras using larger sensors. Some cameras use a larger sensor including, at the high end, a pricey full-frame sensor compact camera, such as Sony Cyber-shot DSC-RX1, but have capability near that of a DSLR.

Starting in 2011, some compact digital cameras can take 3D still photos. These 3D compact stereo cameras can capture 3D panoramic photos with dual lens or even single lens for play back on a 3D TV.

Rugged compact cameras typically include protection against submersion, hot and cold conditions, shock and pressure. Terms used to describe such properties include waterproof, freeze-proof, heatproof, shockproof and crushproof, respectively. Nearly all major camera manufacturers have at least one product in this category. Some are waterproof to a considerable depth up to 100 feet (30 m);

GoPro and other brands offer action cameras which are rugged, small and can be easily attached to helmets, arms, bicycles, etc. Most have wide angle and fixed focus, and can take still pictures and video, typically with sound.

The 360-degree camera can take picture or video 360 degrees using two lenses back-to-back and shooting at the same time. Some of the cameras are Ricoh Theta S, Nikon Keymission 360 and Samsung Gear 360. Nico360 was launched in 2016 and claimed as the world"s smallest 360-degree camera with size 46 x 46 x 28 mm (1.8 x 1.8 x 1.1 in) and price less than $200. With virtual reality mode built-in stitching, Wifi, and Bluetooth, live streaming can be done. Due to it also being water resistant, the Nico360 can be used as action camera.

Bridge cameras physically resemble DSLRs, and are sometimes called DSLR-shape or DSLR-like. They provide some similar features but, like compacts, they use a fixed lens and a small sensor. Some compact cameras have also PSAM mode.manual focus mode and some have a separate focus ring for greater control.

Big physical size and small sensor allow superzoom and wide aperture. Bridge cameras generally include an image stabilization system to enable longer handheld exposures, sometimes better than DSLR for low light conditions.

As of 2014, bridge cameras come in two principal classes in terms of sensor size, firstly the more traditional 1/2.3" sensor (as measured by image sensor format) which gives more flexibility in lens design and allows for handholdable zoom from 20 to 24 mm (35 mm equivalent) wide angle all the way up to over 1000 mm supertele, and secondly a 1" sensor that allows better image quality particularly in low light (higher ISO) but puts greater constraints on lens design, resulting in zoom lenses that stop at 200 mm (constant aperture, e.g. Sony RX10) or 400 mm (variable aperture, e.g. Panasonic Lumix FZ1000) equivalent, corresponding to an optical zoom factor of roughly 10 to 15.

Some bridge cameras have a lens thread to attach accessories such as wide-angle or telephoto converters as well as filters such as UV or Circular Polarizing filter and lens hoods. The scene is composed by viewing the display or the electronic viewfinder (EVF). Most have a slightly longer shutter lag than a DSLR. Many of these cameras can store images in a raw format in addition to supporting JPEG.

In bright sun, the quality difference between a good compact camera and a digital SLR is minimal but bridge cameras are more portable, cost less and have a greater zoom ability. Thus a bridge camera may better suit outdoor daytime activities, except when seeking professional-quality photos.

In late 2008, a new type of camera emerged, called a DSLR camera that does not require a reflex mirror, a key component of the former. While a typical DSLR has a mirror that reflects light from the lens up to the optical viewfinder, in a mirrorless camera, there is no optical viewfinder. The image sensor is exposed to light at all times, giving the user a digital preview of the image either on the built-in rear LCD screen or an electronic viewfinder (EVF).

These are simpler and more compact than DSLRs due to not having a lens reflex system. MILCs, or mirrorless cameras for short, come with various sensor sizes depending on the brand and manufacturer, these include: a small 1/2.3 inch sensor, as is commonly used in bridge cameras such as the original Pentax Q (more recent Pentax Q versions have a slightly larger 1/1.7 inch sensor); a 1-inch sensor; a Micro Four Thirds sensor; an APS-C sensor found in Sony NEX series and α "DSLR-likes", Fujifilm X series, Pentax K-01, and Canon EOS M; and some, such as the Sony α7, use a full frame (35 mm) sensor, with the Hasselblad X1D being the first medium format mirrorless camera. Some MILCs have a separate electronic viewfinder to compensate the lack of an optical one. In other cameras, the back display is used as the primary viewfinder in the same way as in compact cameras. One disadvantage of mirrorless cameras compared to a typical DSLR is its battery life due to the energy consumption of the electronic viewfinder, but this can be mitigated by a setting inside the camera in some models.

Olympus and Panasonic released many Micro Four Thirds cameras with interchangeable lenses that are fully compatible with each other without any adapter, while others have proprietary mounts. In 2014, Kodak released its first Micro Four Third system camera.

While most digital cameras with interchangeable lenses feature a lens-mount of some kind, there are also a number of modular cameras, where the shutter and sensor are incorporated into the lens module.

The first such modular camera was the Minolta Dimâge V in 1996, followed by the Minolta Dimâge EX 1500 in 1998 and the Minolta MetaFlash 3D 1500 in 1999. In 2009, Ricoh released the Ricoh GXR modular camera.

At CES 2013, Sakar International announced the Polaroid iM1836, an 18MP camera with 1"-sensor with interchangeable sensor-lens. An adapter for Micro Four Thirds, Nikon and K-mount lenses was planned to ship with the camera.

There are also a number of add-on camera modules for smartphones, they are called lens-style cameras (lens camera or smart lens). They contain all the essential components of a digital camera inside a DSLR lens-shaped module, hence the name, but lack any sort of viewfinder and most controls of a regular camera. Instead, they are connected wirelessly and/or mounted to a smartphone to be used as its display output and operate the camera"s various controls.

Sony Cyber-shot QX series "Smart Lens" or "SmartShot" cameras, announced and released in mid 2013 with the Cyber-shot DSC-QX10. In January 2014, a firmware update was announced for the DSC-QX10 and DSC-QX100.DSC-QX30 as well as the Alpha ILCE-QX1,Sony E-mount instead of a built-in lens.

Kodak PixPro smart lens camera series, announced in 2014. These include: the 5X optical zoom SL5, 10X optical zoom SL10, and the 25X optical zoom SL25; all featuring 16MP sensors and 1080p video recording, except for the SL5 which caps at 720p.

Olympus Air A01 lens camera, announced in 2014 and released in 2015, the lens camera is an open platform with an Android operating system and can detach into 2 parts (sensor module and lens), just like the Sony QX1, and all compatible Micro Four Thirds lenses can then be attached to the built-in lens mount of the camera"s sensor module.

Digital single-lens reflex cameras (DSLR) is a camera with a digital sensor that utilizes a reflex mirror to split or direct light into the viewfinder to produce an image.

The sensor also known as a full-frame sensor is much larger than the other types, typically 18mm to 36mm on the diagonal (crop factor 2, 1.6, or 1).interchangeable lenses for versatility by removing it from the lens mount of the camera, typically a silver ring on the front side of DSLRs.

Digital Still Camera (DSC), such as the Sony DSC cameras, is a type of camera that doesn"t use a reflex mirror. DSCs are like point-and-shoot cameras and are the most common type of cameras, due to their comfortable price and its quality.

Cameras with fixed semi-transparent mirrors, also known as DSLT cameras, such as the Sony SLT cameras, are single-lens without a moving reflex mirror as in a conventional DSLR. A semi-transparent mirror transmits some of the light to the image sensor and reflects some of the light along the path to a pentaprism/pentamirror which then goes to an optical view finder (OVF) as is done with a reflex mirror in DSLR cameras. The total amount of light is not changed, just some of the light travels one path and some of it travels the other. The consequences are that DSLT cameras should shoot a half stop differently from DSLR. One advantage of using a DSLT camera is the blind moments a DSLR user experiences while the reflecting mirror is moved to send the light to the sensor instead of the viewfinder do not exist for DSLT cameras. Because there is no time at which light is not traveling along both paths, DSLT cameras get the benefit of continuous auto-focus tracking. This is especially beneficial for burst-mode shooting in low-light conditions and also for tracking when taking video.

A rangefinder is a device to measure subject distance, with the intent to adjust the focus of a camera"s objective lens accordingly (open-loop controller). The rangefinder and lens focusing mechanism may or may not be coupled. In common parlance, the term "rangefinder camera" is interpreted very narrowly to denote manual-focus cameras with a visually-read out optical rangefinder based on parallax. Most digital cameras achieve focus through analysis of the image captured by the objective lens and distance estimation, if it is provided at all, is only a byproduct of the focusing process (closed-loop controller).

A line-scan camera traditionally has a single row of pixel sensors, instead of a matrix of them. The lines are continuously fed to a computer that joins them to each other and makes an image.frame grabber which resides in a PCI slot of an industrial computer. The frame grabber acts to buffer the image and sometimes provide some processing before delivering to the computer software for processing. Industrial processes often require height and width measurements performed by digital line-scan systems.

Many industrial applications require a wide field of view. Traditionally maintaining consistent light over large 2D areas is quite difficult. With a line scan camera all that is necessary is to provide even illumination across the “line” currently being viewed by the camera. This makes sharp pictures of objects that pass the camera at high speed.

Such cameras are also commonly used to make photo finishes, to determine the winner when multiple competitors cross the finishing line at nearly the same time. They can also be used as industrial instruments for analyzing fast processes.

Line-scan cameras are also extensively used in imaging from satellites (see push broom scanner). In this case the row of sensors is perpendicular to the direction of satellite motion. Line-scan cameras are widely used in scanners. In this case, the camera moves horizontally.

This type of digital camera captures information about the light field emanating from a scene; that is, the intensity of light in a scene, and also the direction that the light rays are traveling in space. This contrasts with a conventional digital camera, which records only light intensity.

Many devices have a built-in digital camera, including, for example, smartphones, mobile phones, PDAs and laptop computers. Built-in cameras generally store the images in the JPEG file format.

Mobile phones incorporating digital cameras were introduced in Japan in 2001 by J-Phone. In 2003 camera phones outsold stand-alone digital cameras, and in 2006 they outsold film and digital stand-alone cameras. Five billion camera phones were sold in five years, and by 2007 more than half of the installed base of all mobile phones were camera phones. Sales of separate cameras peaked in 2008.

There are many manufacturers that lead in the production of digital cameras (commonly DSLRs). Each brand embodies different mission statements that differ them from each other outside of the physical technology that they produce. While the majority of manufacturers share modern features amongst their production of cameras, some specialize in specific details either physically on camera or within the system and image quality.

Sales of traditional digital cameras have declined due to the increasing use of smartphones for casual photography, which also enable easier manipulation and sharing of photos through the use of apps and web-based services. "Bridge cameras", in contrast, have held their ground with functionality that most smartphone cameras lack, such as optical zoom and other advanced features.

In response to the convenience and flexibility of smartphone cameras, some manufacturers produced "smart" digital cameras that combine features of traditional cameras with those of a smartphone. In 2012, Nikon and Samsung released the Coolpix S800c and Galaxy Camera, the first two digital cameras to run the Android operating system. Since this software platform is used in many smartphones, they can integrate with some of the same services (such as e-mail attachments, social networks and photo sharing sites) that smartphones do and use other Android-compatible software.

In an inversion, some phone makers have introduced smartphones with cameras designed to resemble traditional digital cameras. Nokia released the 808 PureView and Lumia 1020 in 2012 and 2013; the two devices respectively run the Symbian and Windows Phone operating systems, and both include a 41-megapixel camera (along with a camera grip attachment for the latter).Galaxy S4 Mini with the Galaxy Camera.Leica fixed lens equivalent of 28 mm at F2.8, can take RAW image and 4K video, has 21 mm thickness.Huawei P20 Pro is an android Oreo 8.1 has triple Leica lenses in the back of the smartphone with 40MP 1/1.7" RGB sensor as first lens, 20MP 1/2.7" monochrome sensor as second lens and 8MP 1/4" RGB sensor with 3x optical zoom as third lens.bokeh image with larger high dynamic range, whereas combination of mega pixel first lens and optical zoom will produce maximum 5x digital zoom without loss of quality by reducing the image size to 8MP.

After a big dip of sales in 2012, consumer digital camera sales declined again in 2013 by 36 percent. In 2011, compact digital cameras sold 10 million per month. In 2013, sales fell to about 4 million per month. DSLR and MILC sales also declined in 2013 by 10–15% after almost ten years of double digit growth.

Film camera sales hit their peak at about 37 million units in 1997, while digital camera sales began in 1989. By 2008, the film camera market had died and digital camera sales hit their peak at 121 million units in 2010. In 2002, cell phones with an integrated camera had been introduced and in 2003 the cell phone with an integrated camera had sold 80 million units per year. By 2011, cell phones with an integrated camera were selling hundreds of millions per year, which were causing a decline in digital cameras. In 2015, digital camera sales were 35 million units or only less than a third of digital camera sales numbers at their peak and also slightly less than film camera sold number at their peak.

Early cameras used the PC serial port. USB is now the most widely used method (most cameras are viewable as USB mass storage), though some have a FireWire port. Some cameras use USB PTP mode for connection instead of USB MSC; some offer both modes.

Other cameras use wireless connections, via Bluetooth or IEEE 802.11 Wi-Fi, such as the Kodak EasyShare One. Wi-Fi integrated Memory cards (SDHC, SDXC) can transmit stored images, video and other files to computers or smartphones. Mobile operating systems such as Android allow automatic upload and backup or sharing of images over Wi-Fi to photo sharing and cloud services.

Cameras with integrated Wi-Fi or specific Wi-Fi adapters mostly allow camera control, especially shutter release, exposure control and more (tethering) from computer or smartphone apps additionally to the transfer of media data.

Cameraphones and some high-end stand-alone digital cameras also use cellular networks to connect for sharing images. The most common standard on cellular networks is the MMS Multimedia Messaging Service, commonly called "picture messaging". The second method with smartphones is to send a picture as an email attachment. Many old cameraphones, however, do not support email.

A common alternative is the use of a card reader which may be capable of reading several types of storage media, as well as high speed transfer of data to the computer. Use of a card reader also avoids draining the camera battery during the download process. An external card reader allows convenient direct access to the images on a collection of storage media. But if only one storage card is in use, moving it back and forth between the camera and the reader can be inconvenient. Many computers have a card reader built in, at least for SD cards.

Many modern cameras support the PictBridge standard, which allows them to send data directly to a PictBridge-capable computer printer without the need for a computer.

An instant-print camera, is a digital camera with a built-in printer.instant camera which uses instant film to quickly generate a physical photograph. Such non-digital cameras were popularized by Polaroid with the SX-70 in 1972.

Many digital cameras include a video output port. Usually sVideo, it sends a standard-definition video signal to a television, allowing the user to show one picture at a time. Buttons or menus on the camera allow the user to select the photo, advance from one to another, or automatically send a "slide show" to the TV.

Some DVD recorders and television sets can read memory cards used in cameras; alternatively several types of flash card readers have TV output capability.

Cameras can be equipped with a varying amount of environmental sealing to provide protection against splashing water, moisture (humidity and fog), dust and sand, or complete waterproofness to a certain depth and for a certain duration. The latter is one of the approaches to allow underwater photography, the other approach being the use of waterproof housings. Many waterproof digital cameras are also shockproof and resistant to low temperatures.

Some waterproof cameras can be fitted with a waterproof housing to increase the operational depth range. The Olympus "Tough" range of compact cameras is an example.

Many digital cameras have preset modes for different applications. Within the constraints of correct exposure various parameters can be changed, including exposure, aperture, focusing, light metering, white balance, and equivalent sensitivity. For example, a portrait might use a wider aperture to render the background out of focus, and would seek out and focus on a human face rather than other image content.

Vendors implement a variety scene modes in cameras" firmwares for various purposes, such as a "landscape mode" which prevents focusing on rainy and/or stained window glass such as a windshield, and a "sports mode" which reduces motion blur of moving subjects by reducing exposure time with the help of increased light sensitivity. Firmwares may be equipped with the ability to select a suitable scene mode automatically through artificial intelligence.

Many camera phones and most stand alone digital cameras store image data in flash memory cards or other removable media. Most stand-alone cameras use SD format, while a few use CompactFlash or other types. In January 2012, a faster XQD card format was announced.hot-swappable memory slots. Photographers can swap one of the memory card with camera-on. Each memory slot can accept either Compact Flash or SD Card. All new Sony cameras also have two memory slots, one for its Memory Stick and one for SD Card, but not hot-swapable.

A few cameras used other removable storage such as Microdrives (very small hard disk drives), CD single (185 MB), and 3.5" floppy disks (e. g. Sony Mavica). Other unusual formats include:

Onboard (internal) flash memory — Cheap cameras and cameras secondary to the device"s main use (such as a camera phone). Some have small capacities such as 100 Megabytes and less, where intended use is buffer storage for uninterrupted operation during a memory card hot swap.

Most manufacturers of digital cameras do not provide drivers and software to allow their cameras to work with Linux or other free software.USB mass storage and/or Media Transfer Protocol, and are thus widely supported. Other cameras are supported by the gPhoto project, and many computers are equipped with a memory card reader.

Many cameras, especially high-end ones, support a raw image format. A raw image is the unprocessed set of pixel data directly from the camera"s sensor, often saved in a proprietary format. Adobe Systems has released the DNG format, a royalty-free raw image format used by at least 10 camera manufacturers.

Other formats that are used in cameras (but not for pictures) are the Design Rule for Camera Format (DCF), an ISO specification, used in almost all camera since 1998, which defines an internal file structure and naming. Also used is the Digital Print Order Format (DPOF), which dictates what order images are to be printed in and how many copies. The DCF 1998 defines a logical file system with 8.3 filenames and makes the usage of either FAT12, FAT16, FAT32 or exFAT mandatory for its physical layer in order to maximize platform interoperability.

Most cameras include Exif data that provides metadata about the picture. Exif data may include aperture, exposure time, focal length, date and time taken. Some are able to tag the location.

The filesystem in a digital camera contains a DCIM (Digital Camera IMages) directory, which can contain multiple subdirectories with names such as "123ABCDE" that consist of a unique directory number (in the range 100...999) and five alphanumeric characters, which may be freely chosen and often refer to a camera maker. These directories contain files with names such as "ABCD1234.JPG" that consist of four alphanumeric characters (often "100_", "DSC0", "DSCF", "IMG_", "MOV_", or "P000"), followed by a number. Handling of directories with possibly user-created duplicate numbers may vary among camera firmwares.

To enable loading many images in miniature view quickly and efficiently, and to retain meta data, some vendors" firmwares generate accompanying low-resolution thumbnail files for videos and raw photos. For example, those of Canon cameras end with .THM.

Digital cameras have become smaller over time, resulting in an ongoing need to develop a battery small enough to fit in the camera and yet able to power it for a reasonable length of time.

The most common class of battery used in digital cameras is proprietary battery formats. These are built to a manufacturer"s custom specifications. Almost all proprietary batteries are lithium-ion. In addition to being available from the OEM, aftermarket replacement batteries are commonly available for most camera models.

Digital cameras that utilize off-the-shelf batteries are typically designed to be able to use both single-use disposable and rechargeable batteries, but not with both types in use at the same time. The most common off-the-shelf battery size used is AA. CR2, CR-V3 batteries, and AAA batteries are also used in some cameras. The CR2 and CR-V3 batteries are lithium based, intended for a single use. Rechargeable RCR-V3 lithium-ion batteries are also available as an alternative to non-rechargeable CR-V3 batteries.

When digital cameras became common, many photographers asked whether their film cameras could be converted to digital. The answer was not immediately clear, as it differed among models. For the majority of 35 mm film cameras the answer is no, the reworking and cost would be too great, especially as lenses have been evolving as well as cameras. For most a conversion to digital, to give enough space for the electronics and allow a liquid crystal display to preview, would require removing the back of the camera and replacing it with a custom built digital unit.

Many early professional SLR cameras, such as the Kodak DCS series, were developed from 35 mm film cameras. The technology of the time, however, meant that rather than being digital "backs" the bodies of these cameras were mounted on large, bulky digital units, often bigger than the camera portion itself. These were factory built cameras, however, not aftermarket conversions.

A few 35 mm cameras have had digital camera backs made by their manufacturer, Leica being a notable example. Medium format and large format cameras (those using film stock greater than 35 mm), have a low unit production, and typical digital backs for them cost over $10,000. These cameras also tend to be highly modular, with handgrips, film backs, winders, and lenses available separately to fit various needs.

The very large sensor these backs use leads to enormous image sizes. For example, Phase One"s P45 39 MP image back creates a single TIFF image of size up to 224.6 MB, and even greater pixel counts are available. Medium format digitals such as this are geared more towards studio and portrait photography than their smaller DSLR counterparts; the ISO speed in particular tends to have a maximum of 400, versus 6400 for some DSLR cameras. (Canon EOS-1D Mark IV and Nikon D3S have ISO 12800 plus Hi-3 ISO 102400 with the Canon EOS-1Dx"s ISO of 204800).

In the industrial and high-end professional photography market, some camera systems use modular (removable) image sensors. For example, some medium format SLR cameras, such as the Mamiya 645D series, allow installation of either a digital camera back or a traditional photographic film back.

Most earlier digital camera backs used linear array sensors, moving vertically to digitize the image. Many of them only capture grayscale images. The relatively long exposure times, in the range of seconds or even minutes generally limit scan backs to studio applications, where all aspects of the photographic scene are under the photographer"s control.

Since it is much easier to manufacture a high-quality linear CCD array with only thousands of pixels than a CCD matrix with millions, very high resolution linear CCD camera backs were available much earlier than their CCD matrix counterparts. For example, you could buy an (albeit expensive) camera back with over 7,000 pixel horizontal resolution in the mid-1990s. However, as of 2004

Most modern digital camera backs use CCD or CMOS matrix sensors. The matrix sensor captures the entire image frame at once, instead of incrementing scanning the frame area through the prolonged exposure. For example, Phase One produces a 39 million pixel digital camera back with a 49.1 x 36.8 mm CCD in 2008. This CCD array is a little smaller than a frame of 120 film and much larger than a 35 mm frame (36 x 24 mm). In comparison, consumer digital cameras use arrays ranging from 36 x 24 mm (full frame on high end consumer DSLRs) to 1.28 x 0.96 mm (on camera phones) CMOS sensor.

Cluster and center console display research: how Chinese manufacturers scramble for Mini LED/Micro LE market. The surging demand for intelligent and connected vehicles, in-vehicle infotainment systems and navigation systems among others gives a big boost to the automotive display market.

New York, Jan. 24, 2022 (GLOBE NEWSWIRE) -- Reportlinker.com announces the release of the report "Global and China Automotive LCD Cluster and Center Console Industry Report, 2021" - https://www.reportlinker.com/p06219667/?utm_source=GNW

The statistics from our automotive database show that in 2020 China shipped more than 35 million sets of passenger car displays (cluster, center console, entertainment display, HUD, etc.), up over 4% more than in the previous year.

Automotive display is a key booster to the digital transformation of automotive cockpits. The better performance of on-board computers enables the central computing unit to support LCD cluster, high-resolution infotainment display, HUD, electronic rearview mirror and other display systems, and provides technical support for multi-display systems.

From the new models launched in recent two years, it can be seen that large-size display and multi-screen display have been trends for automotive displays. High-end models have begun to pack at least 4 displays. Products like co-pilot seat entertainment display, control display, rear row entertainment display and streaming media rearview mirror have started finding application, and the demand for large-size displays has been soaring.

The installation of clusters shows that about 60% of new vehicles carry LCD clusters. In the first three quarters of 2021, 6.544 million LCD clusters were installed in passenger cars, a like-on-like spurt of 44.5%, of which 12.0-inch (incl.) to 13.0-inch (excl.) LCD clusters were most installed, up to 2.512 million units, up by 35.0%, and 10.0-inch (incl.) to 12.0-inch (excl.) LCD clusters grew at the fastest pace with the installations rocketing by 173.8% to 1.186 million units.

From center console displays, it can be seen that the installations of large-size ones have surged. In the first three quarters of 2021, 8.0-inch to 9.0-inch center console displays were most installed, up to 4.016 million units, up by 4.3% from the prior-year period, but with the proportion of the total center console display installations down 4.2 percentage points; the installations of 13.0-inch to 15.0-inch center console displays proliferated by 250.6%; that of 15.0-inch and above center console displays multiplied by 204.0%.

Cockpit electronics are heading in the direction of multi-display integration. Early in 2019, emerging carmakers have rolled out mass-produced models like LiXiang One and ENOVATE ME7 with 4 and even 5-screen displays. Traditional OEMs also step up efforts to deploy, having introduced multi-screen display products since 2020.

FAW Hongqi H9 unveiled in August 2020 bears dashboard, center console, and co-pilot seat entertainment displays, 2 rear row entertainment displays, and HUD. In addition, it also packs an electronic image acquisition and display system (i.e., streaming media rearview mirror) which consists of digital camera, image processing and high-definition digital display. The system uses the rear camera to project images onto the display, and displays them on the rearview mirror in digital format.

Great Wall Mecha Dragon introduced in November 2021 is equipped with 10.25-inch dashboard, 27-inch 4K center console display, 25-inch head-up display, two 1.6-inch touch bars, and two rear row capacitive touch screens, as well as external display technology at the rear.

In the future, as standards and regulations are improved, more vehicle displays will be used. For example, in June 2021, Zhejiang Society of Automotive Engineers was approved for release of group standard, the Performance Requirements and Test Methods of Passenger Car Digital Perspective A-pillar System. Neta Auto under Hozon Auto introduced its “transparent A-pillar”-enabled mass-production models with OLED flexible screens as display interfaces. The issuance of this standard will accelerate the application of “transparent A-pillar”.

The soaring demand for vehicle displays give impetus to development of new vehicle display technologies. In current stage, a-Si TFT LCD still prevail in vehicle display market, but advanced display technologies such as LTPS TFT LCD, OLED, mini LED backlight and micro LED are making their way into the market.

The year of 2020 saw the start of production of automotive OLED. Due to high cost, OLED, often larger than 7.2 inches, is largely used in high-end models, with applications including cluster, center console and copilot seat entertainment displays. Suppliers are led by LGD, Samsung Display and BOE.

2021 Mercedes-Benz S-Class sedans differ greatly from the previous generations in application of displays, changing the original siamesed center console display into a large waterfall display, a 12.8-inch vertical waterfall OLED screen with resolution of 1888×1728. They also pack a glasses-free 3D full LCD dashboard, HUD and rear row entertainment display, which connect with each other.

2021 Cadillac Escalade is equipped with an OLED AR perspective curved display with three screens total – a 7.2-inch driver information display, a 14.2-inch digital dashboard, and a 16.9-inch infotainment screen. Wherein, the cluster option features a large speedometer displaying temperature and time at the left and dynamics at the right. In addition, the display is in night mode where infrared technology is used to observe farther than human eyes.

Mini LED is a necessary transition phase from fine pitch LED to Micro LED. At present, most vehicle display technology companies have deployed Mini LED and Micro LED, and ever more vehicle projects use mini LED backlight technology. One example is Cadillac Lyriq EV in which GM plans to use a 33-inch mini LED backlit display in 2022.

In November 2021, Mecha Dragon, the first model of SL, a high-end brand of Great Wall Motor made a debut at Auto Guangzhou. The Mini-LED external display technology at the rear of this model enables display of user-defined content, the first attempt to apply Mini-LED in cars.

Automotive displays head in the direction of large size and multi-screen integration, and the surging demand creates huge room to grow. Various suppliers are therefore trying hard to deploy innovative technologies such as Mini LED and Micro LED.

Tianma Microelectronics: in 2020 it first outran JDI and became the world’s largest vehicle display company in terms of shipments. The company supplies through Tier1s, covering 92% of global customers (top 24 Tier1s) and 100% of Chinese brands (top 10).

Tianma Microelectronics works to deploy Mini LED and Micro LED technologies. Following the on-site exhibition of its self-developed LTPS AM Mini LED HDR display at annual meeting of Society for Information Display (SID) early in 2019, the company showcased its Micro LED technologies online at SID 2021, including 5.04" Splitting ultra-narrow bezel Micro LED, the world’s first 7.56" transparent Micro LED, and innovative technology applications combined with electronic paper.

Moreover, its self-developed Hybrid TFT Display (HTD) technology is in the phase of verification for mass production. The company has deployed HTD on its flexible AMOLED production lines, and will achieve mass production based on the advanced drive and backplane technologies with lower power consumption.

HGC Lighting Solutions: the new-generation white light Mini LED vehicle backlight display module features automotive-grade reliability, ultra-thin display body, multi-zone dynamic control, and million-level ultra-high contrast.

This white light Mini LED display module uses automotive chip and self-developed superior ACSP chip-scale packaging technology. By removing the cost of QD and DBEF and upgrading the production process, it not only delivers automotive-grade reliability but cuts 15-25% production cost. The company have spawned and delivered white light Mini LED vehicle display series products and partnered with several well-known automakers.

TCL CSOT: in November 2021, TCL CSOT joined hands with Yanfeng to roll out the industry’s first under-screen camera-based automotive intelligent display. Combining TCL CSOT’s blind-hole optical design with the smoked black processing method and Yanfeng’s HMI design, the product embeds a camera into backlight hole to enable an integrated under-screen camera solution, that is, the DMS camera is hidden in the display.
