Abstract:
At least one image processing apparatus is provided for preventing inadequate correction of, and to properly correct, a blur component in an image from occurring. The at least one image processing apparatus generates an image recovery filter for correcting chromatic aberration from an optical transmission function (OTF), and corrects the chromatic aberration of a captured image using the image recovery filter. Further, the at least one image processing apparatus calculates characteristics of a color blur of each area in a case where the image recovery filter has been used. Furthermore, the at least one image processing apparatus detects the remaining color blur in an edge of the image on which the chromatic aberration has been corrected using the image recovery filter from a result of calculating the characteristics of the color blur, and removes the color blur.
