Description

The HD49815TF is a CMOS IC that has been developed as a digital signal-processing IC for CCD-camera digital-signal-processing systems.

Features

? 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-signal-processing system.

? The HD49815TF provides the zoom function and controls the 1- to 256- times linear zoom. It also provides the half-mirror function.

? Since the HD49815TF can be made compatible with the former product, HD49811TFA, through software, a shorter development term is enabled.

? Since software controls AWB, AE, and AF, any protocol can be prepared according to the camera shooting conditions.

? Programmable TG enables use of any CCD device.
