ABSTRACT:
An image data decoding system for processing compressed data including variable-length codes and fixed-length codes in digital code series, capable of significantly reducing overall data processing time duration and also reducing a size and scale for a circuit therefor. The image data processing system includes: extracting portion which extracts the variable-length code and the fixed-length code from the digital code series; a processor which processes data based on a value obtained from the digital code series; a self-running decoder which starts to decode the variable-length codes in parallel with data processing in the processor, upon receipt of a start signal from the processor; compare unit which compares the variable-length code and the condition for stopping self-running decoding decoder; and image reconstructing unit which reconstructs image in accordance with a plurality of parameters obtained from the processor and the self-running decoder.
