Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To prevent the narrowing of the dynamic range of a CCD solid-state image pickup element mounted with a color filter of a mosaic type by temporarily synthesizing and separating information charge two photodetection picture elements adjacent in the transferring direction of the information charge within the blanking period of horizontal scanning and synthesizing again and transfer- outputting the information charge between the photodetection picture elements.

This mixing operation is switched by each field to raise the clock ϕv1 at an odd numbered field and to raise the clock ϕv3 at an even numbered field. At the time of repeatedly synthesizing the information charge of the two elements in the blanking period of horizontal scanning, as information charge is stored in each photodetection picture element by an amount obtained by averaging the two picture elements though there is difference between the photodetection sensitivity of each photodetection picture element, a phtodetection picture element corresponding to the component of high photodetection sensitivity is hardly saturated.
