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.
• 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.
