Patent ID: 7706583

Claim:
An image processing apparatus for receiving and processing a plurality of moving image signals, and outputting one moving image signal, said image processing apparatus comprising: a first image input unit which inputs a first moving image signal; a second image input unit which inputs a second moving image signal; a band segmentation unit which segments a first frame image in the first moving image signal into a plurality of different frequency band components and which segments a second frame image in the second moving image signal into a plurality of different frequency band components; and an image composition unit which composites the first frame image and the second frame image, each of the first frame image and the second frame image having been segmented by said band segmentation unit, by replacing some or all image data in common frequency band components between the first frame image and the second frame image, and which generates a third moving image signal composed of composited frame images, wherein, when the output of said image processing apparatus is switched from the first moving image signal to the second moving image signal, said image composition unit outputs the third moving image signal in an interval of the first moving image signal and the second moving image signal.
