1. A video processing device, comprising:
a receiver that successively receives, as input images, images successively generated, each input image of the input images having a prescribed superimposing image superimposed selectively in one or more areas of the input image based on external information;
a compositing image generation circuit that successively generates compositing images to be combined with the one or more areas of the input image based on the external information;
a video compositing circuit that successively generates composite images in which a compositing image is combined with the input image by replacing the one or more areas of the input image with the compositing image;
a compositing abnormality detection circuit that determines whether one or more areas of a composite image generated by the video compositing circuit have abnormality or not, the one or more areas of the composite image corresponding to the replaced areas of the input image;
a comparison circuit that compares the one or more areas of the input image with the one or more areas of the composite image to determine whether or not respective areas match, if it is determined that the one or more areas of the composite image do not have abnormality; and
an output control circuit that outputs the input image if it is determined that the one or more areas of the input image and the one or more areas of the composite image match, and outputs the composite image when it is determined that the respective areas do not match.
