Abstract
A reflection correction processing unit extracts at least color information from a peripheral area of a processing target pixel having a high luminance in an input image, and performs control, to the processing target pixel, to reduce the luminance of the processing target pixel and to bring a chrominance signal of the processing target pixel close to a predetermined chrominance signal ratio. In a case where a chrominance signal ratio based on the color information is close to the predetermined chrominance signal ratio, the reflection correction processing unit increases an intensity of the correction to the processing target pixel.
