Abstract:
1. An image processing apparatus for correcting for degradation in image quality due to aberrations of an optical imaging system of an image capture apparatus in an image captured by the image capture apparatus, comprising: a first chromatic difference of magnification correction unit configured to perform correction of a chromatic difference of magnification of the optical imaging system for the image; a first obtaining unit configured to obtain a first value related to coloring of the image in which the chromatic difference of magnification has been corrected; an image recovery processing unit for applying, to the image in which the chromatic difference of magnification has been corrected, an image recovery filter based on a point spread function of the optical imaging system; a second obtaining unit configured to obtain a second value related to coloring of the image to which the image recovery filter has been applied; and a pixel value correction unit configured to correct a pixel value of the image which has been applied with the image recovery filter according to a difference between the first and second values obtained by said first obtaining unit and said second obtaining unit; and wherein the first chromatic difference of magnification correction unit, the first obtaining unit, the image recovery processing unit, the second obtaining unit and the pixel value correction unit are implemented by one of hardware and a processor that executes software or a combination of hardware and a processor that executes software.
