SOLID-STATE IMAGE PICKUP DEVICE AND SYSTEM ON-CHIP SOLID- STATE IMAGE PICKUP DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent image quality deterioration by suppressing fluorescent lamp flicker occurring in a striped horizontal pattern shape when a photograph is taken with a MOS image pickup device under fluorescent lamp lighting. SOLUTION: An output waveform of a photometric element 103 and electronic shutter value that is an output of an electronic shutter setting part 104 are inputted to a control value generating part 105 and gain control value is produced. And, fluorescent lamp flicker is suppressed by such a manner that a gain control part 106 controls the gain of a video signal that is successively read from an image pickup device 101 by a horizontal scanning part 203 in every horizontal line.
