Storage
Memory card CompactFlash .
Digital cameras cell phones or cameras also use cheap memory or flash memory. They are commonly used memory cards: CompactFlash (CF), Secure Digital (SD), xD cards and Memory Stick for Camera Sony . Previously used disks 3 1 / 2 ” for storage of images.
The photos are stored in files JPEG format or in standard TIFF or RAW to get a better picture quality despite the large increase in file size. Video files are commonly stored in formats AVI , DV , MPEG , MOV , WMV , etc.
Almost all digital cameras use compression techniques to maximize storage space. The techniques of compression often take advantage of two common features in the photographs:
patterns: an image is very common to find areas where you see the same color (or the same sequence) repeated several times (for example, a white wall). Such areas can be coded so that the storage space needed for them to decrease. This type of compression does not usually get large percentages of decline.
irrelevance, like codification mp3 takes advantage of the auditory system’s inability to detect certain sounds (or lack thereof), in digital cameras you can use a compression is to remove information that the camera has captured, but the eye man is going to be unable to perceive.
