ABSTRACT:
It is an object of the invention to provide a method of reducing flicker noises in an X-Y address type solid-state image pickup device for reducing flicker noises generated by a fluorescent light for room illumination when taking a picture in door.A configuration is provided in which signal storage time ts resulting in no flicker noise under a fluorescent lamp having an emission frequency of 120 Hz is preset (step S1); average luminance of image data is calculated for each frame in a predetermined average luminance detection area allocated in the frame (step S2); a difference in average luminance is calculated between frames (step S3); and the signal storage time ts is changed based on the difference in luminance (steps S4, S5and S6).
