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.
532(H) 508(H)
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.
