Abstract:
An image processing apparatus includes an image obtaining portion 200 that obtains a first and second images having exposures different from each other, a region selecting portion 203 that selects a first region different from a region containing a luminance saturation part from the first image, and that selects a second region corresponding to the region containing the luminance saturation part of the first image from the second image, an image restoration processing portion 201 that performs an image restoration processing using an image restoration filter generated based on an optical transfer function for the first region of the first image and the second region of the second image, and an image replacing portion 202 that replaces the region containing the luminance saturation part of the first image with the second region of the second image so as to synthesize the first and second regions to generate one image.
