To automatically set an appropriate parameter value corresponding to moving image data and to generate and output images whose resolution is increased appropriately without putting burdens on a user.
An image processor is provided with a means for selecting a frame (called "support frame" hereafter) to be composited with a base frame on the basis of the degree of image change from the base frame, a means for executing a compositing processing on the basis of the image data (called "base image data" hereafter) of the base frame and the image data of the support frame and generating the image data (called "composite image data" hereafter) in which the number of pixels is larger than the base image data, and a means for executing the output processing of the base frame on the basis of the composite image data.
