HD49815TF
HD49815TF is Digital Camera Signal Processor manufactured by Renesas.
Description
The HD49815TF is a CMOS IC that has been developed as a digital signal-processing IC for CCD-camera digitalsignal-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 microputer, 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 patible 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.
