<P>PROBLEM TO BE SOLVED: To provide an image processing device, an image processing method, and an image processing program capable of precise composition even when a plurality of images including a moving subject differ in brightness. <P>SOLUTION: The image processing device comprises: means which generates a comparison image on the basis of photographing control information of a reference image and that of a non-reference image; means which calculates motion data between the reference image and the comparison image; means which divides the reference image, the non-reference image, and the comparison image into image blocks; means which calculates the average of pixel output values of each image block of the reference image and the comparison image associated by the motion data; means which identifies a threshold used to determine whether the reference image and the non-reference image can be composed, by each image block; means which compares a difference from the threshold with the threshold to determine whether the composition is possible; and means which when it is determined that the composition is possible, determines the composition ratio of the image block on the basis of the average of the reference image. <P>COPYRIGHT: (C)2012,JPO&INPIT |
