The image processor 1 includes a frequency transform unit 12, an encoding unit 15, and a memory 4. The encoding unit 15 includes a DC processing unit 31 that generates a direct-current stream, an LP processing unit 32 that generates a low-frequency stream, an HP processing unit 33 that generates an upper high-frequency stream and a lower high-frequency stream, and an output unit 34 having output ports 41 to 44 to output the direct-current stream, the low-frequency stream, the upper high-frequency stream, and the lower high-frequency stream to the memory 4.
