1. CCD (IC1)
Operating Voltage: +15V, -5.5V
Effective Number of Pixels: 659 x 494
Image Size: 1/4 type
Color Filter: Original Colors RGB
Package: 14pin Plastic DIP
The CCD is driven by the horizontal driving signal (H1, H2, RG) and the
vertical driving signal (V1, V2A, V2B, V3) output from the DSP (IC2).
The subject image focused by a lens is converted to electrical signals,
read out by the driving signal and input to the DSP through IC1(pin 7)
to Q1.
2. DSP (IC2)
Characteristics: AFE, V-driver, 3-chip SEP (System Embedded
Package) of the Signal Processing DSP
Power Supply: +3.3V, +2.9V
Function: CCD Drive, CDS, AGC, A/D, Luminance Signal Processing
(gamma correction, outline correction etc.)
Color Signal Processing (White Balance, Matrix etc.), Automatic flaw
correction AE/AWB/AGC control by the Signal Processing DSP
microcomputer, Fluorescent lamp flicker-free
Package: 312pin Ceramic BGA
Clock Frequency: 24.5454MHz
<AFE Chip>
The specified sampling is performed in the CDS circuit inside the AFE chip and the noise of the CCD
output signal is removed. After it is adjusted to the specified level according to the instruction from the
Signal Processing DSP in the GCA circuit, it is converted to 10-bit digital signal by the A/D converter
inside the AFE chip and input to the Signal Processing DSP.
Power (+3.3V) is supplied through L4 and L5 after the ON/OFF control by the Signal Processing DSP.
<V-driver Chip>
Generates the CCD power supply of +15V and -5.5V from the input of +3.3V by the external L3, D3, D4,
C10 and C11.
Generates 3-values V-drive signal for CCD driving by a timing signal from the Signal Processing DSP.
<Signal Processing DSP Chip>
Processes the AFE output signal, and outputs the Analog Y signal and C signal. Outputs the CCD
driving signal.
The built-in microcomputer performs the AE (Auto Exposure) and AWB (Auto White Balance)
processing, and the Read/Write for each control and setting. The Read/Write for each setting to the IC is
performed by the Main CPU (IC102) on the Main Board on I2CBUS (SDL, SDA).
