Abstract
An input image containing multiple kinds of blur is corrected without using multiple images, resulting in a target image with less blur than the input image. An image correction apparatus (100) for correcting an input image to generate a target image with less blur than the input image is provided, which includes: an adaptive region division unit (110) that divides the input image into a plurality of adaptive regions based on pixel values of pixels included in the input image; a PSF interpolation unit (120) that interpolates a point spread function for a pixel located between representative pixels each representing a corresponding one of the adaptive regions, using a PSF representing characteristics of image blur calculated for each of the adaptive regions; and an image correction unit (130) that corrects the input image using the point spread functions available after the interpolation, so as to generate the target image.
