Abstract
An image capturing unit outputs both a valid video signal (a primary video signal) and an unnecessary video signal (a secondary video signal) as an output signal; a flash detection unit detects white band interference caused by an external flash; and a flash correction unit delays the valid video signal using a first delay unit and delays the unnecessary video signal using a second delay unit. When white band interference has occurred, the outputs of the respective delay units are added together by an adding unit, generating a corrected signal. An output selection unit selects and outputs the signal from the first delay unit in normal times, and when interference caused by an external flash has occurred, selects and outputs the corrected signal.
