Claim Text:
1. An image processing apparatus comprising: an acquisition unit which acquires a first image group including plural images, the plural images being obtained by sequentially photographing motion of an object; an area setting unit which sets plural areas at plural positions on each of the images of the first image group acquired by the acquisition unit; a threshold value setting unit which sets representative values of pixel values of the plural areas of a prescribed number of images falling within a prescribed period as threshold values for specifying plural images relating to specific moments of motion of the object; a first calculation unit which calculates respective evaluation values for each of the plural areas set on each of the plural images; a determination unit which determines whether the respective evaluation values calculated by the first calculation unit for each of the plural areas are larger than corresponding ones of the representative values; and a specifying unit which acquires pixel values of the plural areas set on each of the images by the area setting unit, and specifies a first image having plural areas in which the object appears, the first image being photographed first, and a second image having plural areas in which the object appears, the second image being photographed latest, from among plural images of a second image group, the second image group including the plural images relating to the specific moments of motion of the object from among the first image group including the plural images, and the specifying unit specifying the first image and the second image based on a change in the acquired pixel values of the plural areas when the determination unit determines that the evaluation values of the plural areas are larger than the corresponding threshold values.
