A digital camera first carries out R component and B component interpolation processing on image data. Then, magnification chromatic aberration correction processing is carried out on the image data that has undergone R component and B component interpolation processing. Then, G component interpolation processing is carried out on the image data that has undergone magnification chromatic aberration correction processing. In carrying out G component interpolation processing, a determination is made as to the G components of which pixels to use in the interpolation processing based on R components or B components of the image data that has undergone magnification chromatic aberration correction processing.
