Patent ID: 7373001

Claim:
A compressed moving image decompression device, comprising: a software processing section that decompresses compressed moving image data by software; a data storage section that stores the moving image data that has been processed by the software processing section; and a hardware processing section that decompresses the moving image data from the data storage section by hardware, the software processing section performing decode processing of a variable length code of the compressed moving image data that has been variable-length coded, and the hardware processing section including a plurality of processing sections that perform inverse quantization and subsequent processing of the moving image data that has been decompressed by the software processing section, the software processing section including a data compression section that compresses the moving image data to be stored in the data storage section, the hardware processing section including a data decompression section that decompresses the moving image data from the data storage section, the data compression section counting the number of zero data items continuously arranged on at least one pixel line and compressing the zero data items into a zero data count value, the data storage section including a plurality of types of packets, each of the packets storing the moving image data of a given number of bits, and each of the types of the packets being identified by a higher-order bit of the moving image data, and the data compression section using the packets depending on whether the packets store compression data or uncompression data.
