3 CCD (IC802) A charge-coupled device in which charges are introduced when light from a scene is focused on the surface of the device. The image points are accessed sequentially to produce a television-type output signal. Effective picture element: 249,936 = 508 (H) x 492 (V) PHIS1 ~ PHIS4: Clock pulse for the storage. PHI1 ~ PHI4: Clock pulse for the image pickup. PHIH1 ~ PHIH2: Clock pulse for the horizontal shift register. PHIR: CCD analog signal output.
4 Camera Signal Processor (IC801) D0 ~ D7: Digital signal of the luminance and the color difference B-Y and R-Y signal. CCD IN: CCD analog signal input. VI1 ~ VI4/VS1 ~ VS4: Clock pulse for the CCD control signal. From/to CPU

Timing Generator
Sample Hold Selects a desired signal from the CCD. Timing Genarator Generates the clock pulse for the CCD. 8-bit AD converter Analog signal from the CCD is converted into 8-bit digital signal of the luminance and the color difference B-Y and R-Y signal. .
