Abstract
An exposure control unitcontrols a charge accumulation time for a CMOS sensor. The CMOS sensorcaptures an image Pwith a charge accumulation time Tand an image Pwith a charge accumulation time T. The charge accumulation time Tdoes not cause a flicker in an image under a light source blinking at a first blink cycle. The charge accumulation time Tis different from the charge accumulation time T. A difference image generation unitgenerates a difference image DP that emphasizes to show a difference in luminance of the images Pand P. A flicker detection unitdetects a flicker occurrence in the image Pbased on a difference in luminance between Pand Pappearing in the difference image DP.
