Abstract:
1. An image processing apparatus comprising: an image separation section for separating a plurality of color component images forming a blurred image which is captured in accordance with a contribution level to a brightness component into a first image and a second image having a smaller contribution level to the brightness component than the first image; an image restoration processing section for performing an image restoration process with regard to each of the first and the second images based on a predetermined image restoration algorithm including an iterative computation using a PSF image representing a point spread function which is defined by an image capturing condition and iteratively processing the image, at least once, until a difference between the image after any processing and the immediately preceding image is less than a predetermined threshold value; wherein the iterative computation performs computation on any portion of a particular image and repeats the computation process on all or substantially all of the previously computed processed portion; a parameter setting section for setting parameters of the iterative computation including the threshold value: and a restored image generating section for generating a restored image corresponding to the blurred image based on the first and the second images having been subjected to the image restoration process; wherein the parameter setting section sets the threshold value with regard to the second image greater than the threshold value with regard to the first image.
