摘要

PROBLEM TO BE SOLVED: To accomplish a configuration to produce images of a uniform black level through image correction processing using parameters corresponding to divisional regions of an image pickup device. SOLUTION: In a configuration to execute a correction process by inputting output signals individually corresponding to divisional regions of an image pickup device, a digital signal processor (DSP) performs correction using individual correction parameters corresponding to the divisional regions. As correction parameters, a clamp level value (a) corresponding to a divisional region to be corrected, a differential value (b) between the clamp level corresponding to the divisional region to be corrected and a target black level and an added value of the values (a) and (b) are input, and an image correction process is executed with the black level determined based on the correction parameters as a criterion.
