PROBLEM TO BE SOLVED: To make it possible to reduce an influence of correction of chromatic aberration of magnification on a subject much containing a specific wavelength area. ! SOLUTION: A chromatic aberration interpolation circuit 106 extracts color ratio data (R/G) of a peripheral pixel of a pixel of interest from a color ratio plane signal R/G calculated by a color ratio calculation circuit 107. Then, when the color ratio data is greater than a first threshold and is equal to or smaller than a second threshold, a correction amount of chromatic aberration of magnification is set to a correction amount which is weaker than a normal correction amount and is calculated in accordance with a predetermined formula, and when the color ratio data is equal to or greater than the second threshold, the correction amount of chromatic aberration of magnification is set to 0. !
