A 1/3-inch 630 k-pixel IT-CCD image sensor with multi-function capability

Recent agreement on specifications for DV-C (digital video for consumer) is going to accelerate enhancing of picture resolution and special features of consumer video cameras. Added to a vibration stabilizer and an electronic zoom now considered indispensable functions, high-quality 16:9 wide picture that follows wide-aspect TV sets increasing in consumer markets is anticipated. This high-resolution multi-function CCD meets these demands. For lower power consumption, 3.3 V driving of H-CCD is used. Bias-preadjust circuits using analog memories are built on the CCD chip, enabling a substrate (VOFD) bias to be free from external adjustment and a reset gate to be driven with 3.3V pulses without external bias adjustment.
