Abstract
A semiconductor integrated circuit includes a check unit which compares a value of a pixel of interest with values of neighboring pixels contained in an image signal supplied from an image sensor, and determines based on the comparison whether the pixel of interest is defective, and a defect correcting unit which corrects the value of the pixel of interest by using values of surrounding pixels in response to the determination by the check unit that the pixel of interest is defective.
