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-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.
