The present invention is an image processing apparatus that reconstructs one frame of image data using block-level image data, including a unit that receives the block-level image data to which position information has been added, a unit that determines whether or not there was an error in the transmission of the received position information, a first storage area used for storing the block-level image data corresponding to the position information for which a transmission error did not occur, a second storage area used for storing the block-level image data corresponding to the position information for which a transmission error occurred, a unit that infers correct position information for the block-level image data stored in the second storage area based on the first storage area and the second storage area, and a unit that reconstructs the one frame of image data using the inferred position information.
