ABSTRACT:
In a method and apparatus for decoding an image data block having multiple data lines compressed into codeword streams, when one of multiple different code types and a line-end code, which are defined by a run-length encoding algorithm, is detected in an N-bit part of an M-bit segment of the codeword streams, the detected one of the code types and the line-end code is interpreted to generate a decompressed output. The N-bit part is further analyzed to find a succeeding one of the code types and the line-end code therein. When an error is detected in the N-bit part, a miss code is outputted to stop interpretation and further generation of the decompressed output. Analysis of the N-bit part is continued until the line-end code is detected. The line-end code is then interpreted so as to complete decompression of one of the data lines.
