Abstract
In an encoder as a compression encoding apparatus for compression encoding an inputted image signal in accordance with a rule of the MPEG or the like, other compression and decompression different from a main compression encoding which is executed by a motion detection/compensation processing circuit, a discrete cosine transforming/quantizing circuit, and a Huffman encoding circuit are executed. The compression and decompression are executed by a signal compressing circuit and a signal decompressing circuit. As mentioned above, by reducing an amount of information that is written into a memory provided in association with the compression encoding apparatus, a capacity of the memory can be decreased. By executing other compression and decompression different from a decoding process corresponding to the compression encoding to a decoding apparatus according to the rule of the MPEG or the like, a capacity of a memory provided in association with the decoding apparatus can be reduced.
