Abstract:
An image processing apparatus for concealing moving image data transmitted from a transmission apparatus, comprising:a receiver arranged to receive moving image data composed of a plurality of successive pictures, error correction check codes, and correlation information indicating correlations between the plurality of successive pictures of the moving image data through a transmission path, the correlation information having been generated by the transmission apparatus by detecting the correlations between the plurality of successive pictures of the moving image data and transmitted with the moving image data and the error correction check codes from the transmission apparatus through the transmission path;an error correction unit adapted to correct errors in the moving image data by using the error correction check codes; andan error concealment unit adapted to select one of previous and following pictures of a current picture in accordance with the correlation information received by said receiver and to conceal uncorrectable errors in the image data by replacing image data in the current picture with image data of a selected picture in accordance with an error correction operation executed by said error correction unit.
