Abstract:
1. An image processing device comprising: a reception unit configured to receive (1) encoded image data encoded in units of blocks of image data and (2) reference information representing whether or not a block of the image data is selected as reference image data when another block is encoded; a judgment unit configured to judge from the received reference information, in a case where an error occurs in the block, whether or not the block in which the error occurs is selected as reference image data when the another block is encoded; and a retransmission request unit configured to execute the retransmission request for the block in a case where it is judged by the judgment unit that the block in which the error occurs is selected as reference image data when another block is encoded, and to not execute the retransmission request for the block in a case where it is judged by the judgment unit that the block in which the error occurs is not selected as reference image data when another block is encoded.
