A/D Converter
Relevance (video)
Definition A device that converts analog information (a photograph or video frame) into a series of numbers that a computer can store and manipulate. All digicams use an A/D converter, the higher the bit rate the better the output. Modern hi-res digicams employ a 12-bit or 14-bit A/D to increase the dynamic range (range of light from highlight to shadow)
