Image composer for composing an image by extracting a partial region not common to plural images

摘要

In an image composer includes a storage for storing a first and a second image, a region classifier compares the first image with the second image to extract as a non-common sub-region a partial region of one of the two images that does not have a similar pixel property to that of the other image. An image composing unit superimposes the extracted non-common sub-region of one of the images onto the other image to produce a resultant composite image.
