PROBLEM TO BE SOLVED: To suppress erroneous correction of an edge by correcting defective pixels about respective pixels of RGB, when performing dynamic defective pixel correction of the output signal from a solid-state imaging device. SOLUTION: An information storing part 11 stores a pixel signal level of an imaging device, a slanting edge determination control part 12 determines the existence/absence of a slanting edge by comparing a difference in a pixel signal level with a threshold from the pixel signal level of the imaging device stored in the information-storing part 11; a defective pixel determination control part 13 sorts pixel signal levels of the same color from output signal levels of the imaging device, stored in the information storing part 11, to determine the existence/absence of a defective pixel, by comparing the difference in a sorted adjacent pixel signal level with the threshold; and a defective pixel correction control part 14 performs defective pixel correction, according to the result of determination by the slanting edge determination control part and the result of determination by the defective pixel determination control part.
