The HD49815TF provides camera-signal processing, TG, SSG, zoom, and D/A functions and other functions in a single chip and supports high system-integration level. In conjunction with the HD49323AF-01 (CDS/AGC + 10-bit ADC) and the control microcomputer, the HD49815TF forms a three-chip kit that can implement an optimal CCD-camera digital-signalprocessing system. The HD49815TF provides the zoom function and controls the 1- to 256- times linear zoom. It also provides the half-mirror function.
