SOLID-STATE IMAGE PICKUP DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent deterioration in the S/N attended with miniaturization of a solid-state image pickup elements and in a frequency characteristic due to light diffraction effect by an aperture area of an incident light limit section caused by the reduction in a distance between photoelectric conversion elements without losing a signal storage time and continuity of the storage time in a solid-state image pickup section. SOLUTION: The solid-state image pickup device is provided with a summing arithmetic section 4 that applies summing and averaging signals outputted n-times for one vertical scanning period from a solid-state image pickup element 2 at a read interval ratio and outputs the result and an input selection arithmetic section 16 that applies band limit to a prescribed signal band of an output from the summing arithmetic section 4 and gives the input of the result of an incident light control section 3. Then a drive control section 8 controls an element drive section 7 so that the storage time of charges read n-times for one vertical scanning period is almost uniformized thereby enhancing the S/N of the signal and widening the aperture area of the incident light limit section 1.
