Abstract
A progressive-scan interline-transfer CCD (charge coupled device) image sensor (PS-CCD) that can read out vertical signal packets without mixing is presented. It can solve ill-matched resolutions. This 380-k-pixel PS-CCD provides a vertical resolution of 480 TV lines. The schematic of this device is shown. The image area is 6.45 (H) mm*4.84 (V) mm. The number of pixels without optical blacks is 768 (H) *494 (V), and the size is 8.4 (H) mu m*9.8 (V) mu m. These specifications are suitable for 1/2-in lens format. To realize a PS-CCD, three techniques are used: three-phase three-level electrode vertical CCD, dual horizontal CCD with a compound channel, and dual-channel output. The characteristics of the image sensor are shown. 146-mV/1* sensitivity is obtained from one pixel for light with a color temperature of 3200 K and a saturation voltage of 600 mV. Smear is reduced to -86 dB. Horizontal resolution is 570 TV lines.<>Keywords
