In compared to film cameras, digital cameras have a number of advantages, including the display of the image on the camera screen as soon as possible after the registration, you can record one small memory of thousands of images, video with sound records, edit images, and primarily the capacity may be re-used by deleting images. There are numbers of the equipment available was built in digital cameras, such as mobile phones, PDAs, etc. Fit to astronomical devices, such as the Hubble Space Telescope, specialized digital cameras.
Digitizing images on the scanner and digitizing video signals are much older than the creation of still images without sound using digital signals from an array of discrete sensor. Then it was used for the astronauts on board navigation information during their planet. He still pictures Contain the stars and the location of the Planet during transit as well as additional information to the orbiting stadiametric or landing guidance when approaching the planet.
Steven Sasson, engineer at Eastman Kodak, trying to develop the first digital camera with solid state image sensor CCD chips. But it was only the technical execution. Real digital camera was Fuji DS-1 P in 1988. And the first camera was commercialized Dycam 1 Model in 1990. Then in 1991, Kodak began her 100 Kodak DCS. Yet, Casio QV-10 was the first camera of the consumer in 1995, the Nikon D1, 2.74 megapixel digital SLR was first developed in 1999. And in 2003 the Canon 300 D, started the first 600-megapixel camera.
There are different types of digital cameras. For films there are professional video cameras, which are used in the production of cinema and television. The camera comes with inbuilt microphone liquid crystal small video during recording and playback. You can still get pictures of them in one. Webcams, attached to a computer, you can capture the video full of motion and are available from the microphone or the ability to zoom in.
Digital camera live preview is electronic cameras, which can be used to frame and preview before taking the picture, and also view pictures stored. Many of such cameras you can take pictures of traffic. Then you have recorded images can be transferred to computers, printers, or other such devices. USB storage Device enables the camera to function as a disk drive to your computer and is used to transfer images.
To use the FireWire, the storage device is removed from the camera and inserted into another device. Compact digital cameras, small and portable with inbuilt Flash, are easy to use, and the images are stored using a lossy compression. They may be able to capture motion picture, but to the limit. Bridge or SLR camera is a camera as higher end live preview with more advanced features, such as the superzoom lens, film sound, etc. Digital Rangefinder, you supported mechanism, is able to measure the distance of the topic.
Apart from the aforementioned digital cameras, there are other categories. Professional modular digital camera systems are used in studies for commercial production. Line scan camera systems, based on the focusing mechanism, are used in industrial settings to capture images continuously moving materials. They capture images at a very fast with high-resolution images.
Most digital cameras come with pre-set modes for different uses. The data can be transmitted via the USB port, the Firewire port, USB PTP mode and even through wireless connections like Wi-Fi, Bluetooth, etc. These data are stored mainly in Microdrives, joint photography Experts Group (JPEG), tagged image file format (TIFF) and RAW. AVI, MPEG, digital, MOV formats. The MP4 format is also Recently developed. Digital cameras are small, but powerful batteries operate for a sufficiently long period.
