Abstract
A left-eye color discrimination unit () and right-eye color discrimination unit () generate mask images from virtual space images. If an error part exists at the boundary between a chroma key region and non-chroma key region in the mask image, each of a left-eye mask correction unit () and right-eye mask correction unit () corrects the error part using another mask image generated based on the other virtual space image in addition to the virtual space image.
