PROBLEM TO BE SOLVED: To provide a color aberration correction apparatus capable of correcting color aberration in a picked up image without using any special lens for an optical system, and to provide a program used for its implementation. SOLUTION: A reference pixel PB is specified for a specific pixel-of-interest P0 having a pixel value (luminance) lower than or equal to a threshold in RGB data during imaging, for example. On a straight line passing through the pixel-of-interest P0 and an image center O, the reference pixel PB is separated immediately by a distance dr corresponding to a reduction scale or an expansion scale of a blue component value (B value) in an optical image corresponding to an optical zoom magnification in imaging. Only when the B value of the pixel-of-interest P0 is smaller than a B value of the reference pixel PB, the B value of the pixel-of-interest P0 is replaced with the B value of the reference pixel PB. By expanding or shrinking an image only for the blue component from the original RGB data, image data can be obtained in which magnification color aberration has been corrected.
