A 1920(H) Ã\x97 1035(V) Pixel High Definition CCD Image Sensor

A 1920(H) × 1035(V) pixel high definition CCD image sensor has been developed. In order to follow up 74.25 MHz high sampling frequency, as well as to avoid the necessity for ultra fine patterning work for horizontal CCD register electrode formation, the device adopts a dual channel configuration for the horizontal CCD register. To accomplish both vertical signal charge transfer in the V-CCD register and signal charge distribution from the V-CCD registers into the dual channel horizontal CCD registers simultaneously within a 3.77 ¿s short horizontal blanking period, the 1H memory electrode between the V-CCD and H-CCD is introduced. The device operates successfully and a 1000 TV line limiting resolution has been obtained.
