Abstract
A progressive JPEG bitstream may comprise an image component that is comprised of multiple scans of MCUs/data units that are in turn comprised of at least one MCU/data unit segment. Each MCU/data unit segment is successively scanned. The MCU/data unit segment is then reconstructed using multiple entropy decoders operating in parallel on different scans of each MCU/data unit segment.
Claims20
A method of processing an image bitstream, the method comprising:
- determining an image in a user's region of interest;
- successively scanning a data unit segment of the determined image to produce two or more scans;
- decoding, in parallel, the two or more scans of the data unit segments;
- and
- reconstructing the data unit segment according to the two or more decoded scans of the data unit segment, wherein the image in the user's region of interest is reconstructed with a higher image quality.

A system for processing an image bitstream comprising:
- a user interface operable to identify an image in a user's region of interest;
- a scanner operable to successively scan a data unit segments of the image in the image bitstream to produce two or more scans;
- two or more decoders operable in parallel to decode the two or more scans of the data unit segment;
- and
- a circuit operable to reconstruct the data unit segment according to the two or more decoded scans of the data unit segment, wherein the image in the user's region of interest is reconstructed with a higher image quality.
