Abstract:
An image processing system for applying a special effect generation process to a given source picture, comprising:(a) an image data transmission apparatus which comprises target area specifying means for specifying a target area of the given source picture that is to be subjected to the special effect generation process, image data coding means for generating coded data by encoding the source picture, target data relocating means for extracting target data from the coded data generated by said image data coding means and relocating the target data from an original field thereof to a different field of the coded data to obtain a coded bitstream for transmission, the target data being part of the coded data that is corresponding to the target area specified by said target area specifying means, and image data transmission means for transmitting the coded bitstream obtained by said target data relocating means; and (b) an image data reception apparatus which receives the coded bitstream from said image data transmission apparatus, comprising target data extracting means for extracting the target data from the received coded bitstream, target data storage means for storing the target data extracted by said target data extracting means, data reproducing means for reproducing original coded data from the received coded bitstream by restoring the target data into the original field thereof, or reproducing imperfect coded data from the received coded bitstream without restoring the extracted target data, and data decoding means for decoding the original coded data or the imperfect coded data supplied from said data reproducing means.
