ABSTRACT:
A charge transfer device has a plurality of registers which run parallel to each other and across which electrical charges are transferred. For efficient charge transfer across the registers, the transfer elecrtrode of one register and the transfer electrode of an adjacent register are arrayed in contiguity to each other and driven by different driving pulses and a deeper potential is provided in the signal charge receiving side than in the signal charge forwarding side. The registers are arrayed parallel to a sensor row constituted by a linear array of different color sensors and each handle signal charges of the respective colors. In this manner, the outputs from the registers are in the form of the separate color signals to prevent color mixing.
