1. An image processing device that executes deformation of an image, comprising: a candidate area setting unit that sets candidate areas, each of which includes a specific image, on a target image used as a target for a deformation process; an exclusion determination unit that, when there is an overlap between the candidate areas, excludes one or more candidate areas from the target for the deformation process so as to eliminate the overlap, wherein the non overlap areas remain; and a deformation processing unit that performs deformation of the image on the candidate areas other than the excluded candidate areas, wherein the exclusion determination unit, when there are candidate areas of which top sides of the specific images are different from each other, excludes the candidate areas, other than the candidate areas of which the top side of the specific image is oriented in a direction in which the greatest number of candidate areas having the specific images of which the top sides are oriented in the same direction, from the target for the deformation process.
