Abstract
The present invention has an object to provide an image processing apparatus and an image processing method capable of, when reducing a blur in an input image, (i) reducing noise included in the input image and (ii) restraining degradation of the image caused by noise processing from being emphasized by image restoration processing. An image processing apparatus (100) for reducing a blur in an input image includes: a noise processing unit (10) which performs noise processing that reduces noise to the input image, to generate a noise-processed image; and a restoration processing unit (20) which performs image restoration processing that reduces a blur to the noise-processed image, the noise processing unit (10) performing the noise processing based on a characteristic of the image restoration processing.
