IF PRINTED CIRQUIT BOARD WIRING VIEW WAS ONE TONE LIGHTER, THEN 5 STAR RANK HAS TO BE MY CHOISE.
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.
