A digital camera or digicam is a camera that produces still, single frame and may produce moving, multi frame photographs that can be stored in digital memory, displayed on a screen and printed on physical media. Most cameras produced today are digital,1 and while there are still dedicated compact cameras on the market, the use of dedicated digital cameras is dwindling, as digital cameras are now incorporated into many devices ranging from mobile devices to vehicles. However, expensive, high end, high definition dedicated cameras are still commonly used by professionals. Digital and movie cameras share an optical system, typically using a lens with a variable diaphragm to focus light onto an image pickup device. The diaphragm and shutter admit the correct amount of light to the imager, 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. HistoryeditThe history of the digital camera began with Eugene F. Lally of the Jet Propulsion Laboratory, who was thinking about how to use a mosaic photosensor to capture digital images. His 1. 96. 1 idea was to take pictures of the planets and stars while travelling through space to give information about the astronauts position. As with Texas Instruments employee Willis Adcocks filmless camera US patent 4,0. Steven Sasson as an engineer at Eastman Kodak invented and built the first electronic camera using a charge coupled device image sensor in 1. Earlier ones used a camera tube later ones digitized the signal. Early uses were mainly military and scientific followed by medical and news applications. In 1. 98. 6, Japanese company Nikon introduced the first digital single lens reflex DSLR camera, the Nikon SVC. In the mid to late 1. DSLR cameras became common among consumers. By the mid 2. 00. DSLR cameras had largely replaced film cameras. In 2. 00. 0, Sharp introduced the worlds first digital camera phone, the J SH0. J Phone, in Japan. By the mid 2. By the beginning of the 2. Image sensorseditThe 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. Compared to CCDs, CMOS sensors use less power. Cameras with a small sensor use a back side illuminated CMOS BSI CMOS sensor. Overall final image quality is more dependent on the image processing capability of the camera, than on sensor type. Sensor resolutioneditThe resolution of a digital camera is often limited by the image sensor1. 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 cameras pixel count. In a typical sensor, the pixel count is the product of the number of rows and the number of columns. For example, a 1,0. Image at left has a higher pixel count than the one to the right, but has lower spatial resolution. Image sharpnesseditFinal quality of an image depends on all optical transformations in the chain of producing the image. Carl Zeiss points out at the weakest link in an optical chain determines the final image quality. In case of a digital camera, a simplistic way of expressing it is that the lens determines the maximum sharpness of the image while the image sensor determines the maximum resolution. The illustration on the right can be said to compare a lens with very poor sharpness on a camera with high resolution, to a lens with good sharpness on a camera with lower resolution. Methods of image captureedit. At the heart of a digital camera is a CCD or a CMOS image sensor. Digital camera, partly disassembled. The lens assembly bottom right is partially removed, but the sensor top right still captures an image, as seen on the LCD screen bottom left. Since the first digital backs were introduced, there have been three main methods of capturing the image, each based on the hardware configuration of the sensor and color filters. 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. Multi shot exposes the sensor to the image in a sequence of three or more openings of the lens aperture. There are several methods of application of the multi shot technique. The most common originally was to use a single image sensor with three filters passed in front of the sensor in sequence to obtain the additive color information. Another multiple shot method is called Microscanning. This method uses a single sensor chip with a Bayer filter and physically moved the sensor on the focus plane of the lens to construct a higher resolution image than the native resolution of the chip. A third version combined the two methods without a Bayer filter on the chip. 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 of very high total resolution. The choice of method for a given capture is determined largely by the subject matter. It is usually inappropriate to attempt to capture a subject that moves with anything but a single shot system. However, the higher color fidelity and larger file sizes and resolutions available with multi shot and scanning backs make them attractive for commercial photographers working with stationary subjects and large format photographs. Improvements in single shot cameras and image file processing at the beginning of the 2. Filter mosaics, interpolation, and aliasingeditMost current consumer digital cameras use a Bayer filter mosaic in combination with an optical anti aliasing filter to reduce the aliasing due to the reduced sampling of the different primary color images. A demosaicing algorithm is used to interpolate color information to create a full array of RGB image data. Cameras that use a beam splitter single shot 3. CCD approach, three filter multi shot approach, color co site sampling or Foveon X3 sensor do not use anti aliasing filters, nor demosaicing. RAW vs JPGHome.

If you just bought a new camera, you wont be able to open the files until you update your computers software. Worse, many new cameras come out a week before the camera makers software is updated, and if you use software by Adobe, Apple or others, may have to wait weeks or much longer until there is an update. That means you may not be able to open your files today with your new camera if you didnt shoot JPG If you use Photoshop and Adobe Camera Raw, you just might have to buy the newest version of Photoshop, since Adobe doesnt update older versions to read the files from new cameras. Ha Ha Photoshop is so good Ive seen no need to update from CS2, and not shooting raw, I dont have to. If youre shooting action, raw doesnt work. Youll fill an 8 gig card faster than you can imagine. I never shoot raw. Why would I Raw is a waste of time and space, and doesnt look any better than JPG even when you can open the files. INTRODUCTIONCameras all start with raw data and convert this data to JPG images with hardware in the camera. They then throw away the raw data since its no longer needed. Saving this raw data is exactly like people who save twenty years of newspapers in piles around their house. They know they might need the information sometime, but it sure gets in the way Other people think they are crazy. Some fancier cameras save this raw data so you can use software to do the same thing the cameras hardware did, later. Software takes much longer to do the same thing the cameras hardware does, but gives less confident people the chance to try to fix mistakes later. Image quality is the same in JPG and raw.
