Claim Text:
1. An image compositing device, comprising: a motion area detecting section to detect a motion area of a subject based on a base image and at least one comparative image that are photographed at different times; a compositing area setting section to set a compositing area in the comparative image based on the detected motion area; and a composite image generating section to composite the set compositing area with the base image so as to generate a composite image, wherein the motion area detecting section extracts a contour by setting an closed curve in an initial state so that the closed curve encloses a predetermined subject area in a difference image between the base image and the comparative image, and shifting nodes that define the closed curve in a direction in which an energy function of the closed curve is optimized; and wherein the compositing area setting section sets the compositing area based on the contour extracted in the difference image, wherein the image compositing device further comprises: a boundary setting section to set a boundary between the plurality of subject area, wherein the motion area detecting section sets the closed curve in the initial state so that the closed curve does not have an intersection with the boundary.
