PROBLEM TO BE SOLVED: To suppress degradation of image quality, while preventing collapse of a stream buffer.SOLUTION: A determination unit determines to use the coding mode of a second encoding unit when a predetermined target code amount is exceeded, even if the remaining pixel blocks of a specific range are entirely encoded in a second coding mode, as a result of summation of a cumulative code amount generated until a pixel block encoded immediately before a pixel block to be encoded, and a code amount generated by encoding the pixel block to be encoded in a first coding mode, in a specific unit including one or more pixel block. |
