Abstract:
A motion picture coding and decoding system for coding and decoding a motion picture, the system comprising:a first means for providing a current image defined by a concerned region and a set of pixel data of addressed pixels thereon, and an identifying data set for identifying the concerned region in an entire region of the motion picture;a second means responsible for the identifying data set to provide a reference image representative of a previous image of the current image in a current frame;a third means for detecting a motion the reference image has made to constitute the current image;a fourth means responsible for the detected motion to motion-compensate the reference image to generate a prediction image of the current image;a fifth means for generating a difference image between the current image and the prediction image;a sixth means for detecting a configuration of the concerned region;a seventh means for coding the detected configuration, the detected motion, the difference image and the identifying data set, in a compressing manner to output a symbol sequence;an eighth means for decoding the symbol sequence to provide a decoded data set representing the identification data set, a decoded motion representing the detected motion, a decoded configuration representing the detected configuration, and a decoded image of the difference image;a ninth means responsible for the decoded motion to motion-compensate a representative image of the reference image in the current frame to generate a decoded image of the prediction image;a tenth means for adding the decoded image of the difference image to the decoded image of the prediction image to provide a decoded image of the current image;an eleventh means for correcting a configuration of the decoded image of the current image in accordance with the decoded configuration to provide a corrected image of the decoded image of the current iamge; anda twelfth means responsible for the decoded data set to store the corrected image in an identifiable manner to be read as the representative image in the subsequent frame.
