An image processing apparatus for correcting an input image for blur using a recovery filter in accordance with image blurriness includes a blurriness determining unit that receives a target image to be corrected, applies to the target image a recovery filter including a degree-of-blur parameter corresponding to blurriness while changing a value of the degree-of-blur parameter, evaluates a degreeof recovery of each of corrected target images which have been corrected with recovery filters having different degree-of-blur parameter values, and determines blurriness of the target image based onthe degree-of-blur parameter value of the highly evaluated recovery filter; and a blur correction unit that sets a recovery filter for the target image based on the degree-of-blur parameter in accordance with the determined blurriness of the target image and corrects the target image for blur using the recovery filter.
