Image compression/decompression device

A device that performs image compressions/decompressions wherein original image data are compressed on the basis of encoding and encoded data are decompressed comprises one or more image processing units and one or more variable-length encoding/decoding units. The image processing units perform parallel processing according to a number of parallels that is based on a resolution or frame rate of an image, and the variable-length encoding/decoding units perform parallel processing according to a number of parallels that is based on a bit rate of a bit stream processed by the image compression/decompression device. Both or either of the resolution and frame rate of the image that determine the number of parallels is inputted as a parameter to the image compression/decompression device. In this way, power consumption can be reduced in accordance with a user's application purpose that takes account of the resolution, frame rate and bit rate. 种装置，其进行基于编码对原图像数据进行压缩，此外对编码后的数据进行解压缩的图像压缩解压缩处理，其具有个以上的图像处理部以及个以上的可变长度编码解码
