The 10bit CCD output signal from the AFE chip is processed as follows:
1. The outline in the horizontal and vertical directions is corrected
2. The characteristics of gray-scale are corrected by gamma correction.
3. The white balance is corrected.
4. The RGB signal is converted to the luminance signal (Y signal) and the color difference signal (R-Y
(V), B-Y (U) signal).
5. The color saturation and phase are adjusted by color difference matrix.
6. It is output as YUV 8bit signal.
=CCD Driving Signal and Timing Signal Generation=
CCD Driving Signal [For horizontal (H1, H2, RG), vertical (V1, V2A, V2B, V3)], Timing Signal [HREF
Signal, Vsync Signal, and AFE (DS1, DS2, ADCLK, CPOB)] etc. are output. The timing of these signals is
set by a serial signal from the CAMERA CPU.
=AE Control Signal Generation=
Based on the luminance signal level detected by the image signal processing area, the AGC gain
control and the exposure time control to CCD of the AFE chip (by CCD shutter speed control signal
(SUBA Signal (IC2(pin V6) --> C7 --> C6 --> IC1(pin 10))) are performed.
3. Clock
Generated on 24.5454MHz crystal oscillator (X1) on the board.
4. Regulator (IC4)
Input +3.3V, 2.9V
Package: 5pinSOP
