Abstract :
A 1/3-in interline transfer charge-coupled-device (CCD) image sensor with 270000 pixels has been developed. The effective sensing area of (4.8(H)×3.6(V)) mm2 is adopted for the 1/3-in format. This sensor realizes 330 TV lines of color horizontal resolution. In addition, a new on-chip color filter is used, and a minimum object illuminance of 3 1x has been achieved. The electronic shutter was realized by developing the vertical-extraction method, with a wide range of shutter speed from 1/60 to 1/10000 s. Moreover, the use of an embedded photodiode makes it possible to achieve a low dark current. This feature, together with the 5-V drive, gives the sensor additional high performance, including low smear (0.01%)
