1. Horizontal/Vertical edge enhance
2. Gamma correction for grey-level
3. Adjusts level correctly
4. D/A converts for output
- Color signal process
1. RGB matrix to convert to RGB signal
2. White Balance by CAMERA CPU instruction
3. Gamma correction for R/G/B signal respectively
4. Color-Difference matrix to convert to the color-difference signal (R-Y,
B-Y signal) and to adjust chroma/phase
5. Modulation process in accordance with NTSC standard
6. D/A converts for output
Additionally, the detection process for AE (Auto Exposure), AF (Auto Focus) and AWB (Auto White
Balance) is made for automatic control. The detection data is read by the serial signal in CAMERA CPU.
<CCD drive signal and Timing signal generation>
Outputs CCD drive signal [horizontal (H1, H2, RG) and vertical (V1~V4)] and Timing signal [Composite
Synchronization signal, CAMERA CPU interrupt timing signal (VD, EP1, EP2) and signal for CDS IC (SP1,
SP2, ADCLK, OBP)]. The signal timing is set by the serial signal in CAMERA CPU.
- V Driver (IC802)
Power-supply voltages: -5V, +3.3V, +12V
Package: 20pin SOP
Generates CCD vertical drive signal from CCD vertical drive timing
signal in VIDEO DSP (IC803).
CCD vertical drive timing signal with +3.3Vp-p is converted to binary (-
5V~0V) and to ternary (-5V~0V~+12V), and is output as V1~V4 signal.
