Abstract
An apparatus adapted to correct an image data acquired by an image detector including a plurality of detecting elements, includes: a first correction unit adapted for obtaining an offset-corrected image by removing an offset component due to the image detector from the image data, a second correction unit adapted for correcting a pixel value of the offset-corrected image on the basis of a gain of corresponding one of the plurality of detecting elements; and a third correction unit adapted for correcting a value of a selected pixel of the offset-corrected image, the selected pixel being selected based on the pixel value of the offset-corrected image, by generating a pixel value in place of a value of the selected pixel obtained by said second correction unit.
