www.DataSheet4U.com HD49815TF Digital Camera Signal Processor ADE-207-316 (Z) 1st Edition Sep. 1999 Description The HD49815TF is a CMOS IC that has been developed as a digital signal-processing IC for CCD-camera digital-signal-processing systems. Functions CCD-sensor drive-pulse generation (TG) Digital AGC (automatic gain control) Color signal separation circuit RGB matrix RGB gain RGB and Y gamma Color-difference matrix Enhancer RGB and Y setup Digital I/F (4:2:2) Zoom control Mirror reversal Synchronization signal generator for encoding (SSG) AWB, AE, and AF detection Two-channel 8-bit D/A converter 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-signalprocessing system. The HD49815TF provides the zoom function and controls the 1- to 256- times linear zoom. It also provides the half-mirror function. HD49815TF Features (cont) 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. System Block ...
