Abstract: An image processing apparatus includes: a computing unit which determines a first difference value between brightness of a first image data and brightness of a second image data in an overlap area of the first image data including a first brightness characteristic with the second image data having a peripheral area at the center of the first image data and including a second brightness characteristic; and a generating unit which generates a brightness correction parameter for the first image data corresponding to the first difference value.

Abstract: An image processing program, which is executable by a computer and is stored in a recording medium readable by the computer, includes: storing one or more features of a plurality of images, each image having a shape defined by a central angle whose origin is a center of a certain image; setting at least one representative shape defined by a central angle whose origin is a center of a search window for scanning a target image; extracting a first value of the one or more features of the representative shape; extracting a second value of the one or more features of one of the plurality of images; and comparing the extracted first value and the extracted second value and determining an image in the search window as an image candidate for the certain image based on a comparison result.
