Patent ID: 8761496

Claim:
An image processing apparatus comprising: a weight generating section that generates weight data in which a weight of a first region is larger than a weight of a second region, based on at least one of a plurality of to-be-selected images derived from a single to-be-converted image, each of the plurality of to-be-selected images being a result of one or more of a plurality of filters applied to the single to-be-converted image and having substantially the same size as the single to-be-converted image; a calculating section that calculates a degree of similarity between a target image and each of two or more of the plurality of to-be-selected images with a difference between the target image and the to-be-selected image being weighted in each region in accordance with the weight data; and an image selecting section that selects, from the two or more to-be-selected images, one or more to-be-selected images that are more similar to the target image, by referring to the degrees of similarity of the two or more to-be-selected images.
