Beschreibung
Zusammenfassung:	A device that performs an image compression/decompression process of compressing original image data based on encoding and decompressing encoded data includes one or more image processing units and one or more variable length encoding/decoding processing units, and the image processing units perform a parallel process according to a parallel number based on a resolution of an image or a frame rate, and the variable length encoding/decoding processing units perform a parallel process according to a parallel number based on a bit rate of a bit stream processed by the image compression/decompression device. In the image compression/decompression device, both of the resolution of the image and the frame rate or either of the resolution of the image and the frame rate is input as a parameter to decide the parallel number.
