摘要： A water ring scanning apparatus and method, and an apparatus and method for encoding/decoding video sequences using the same are disclosed. A water ring scanning apparatus includes: a preferential scan unit for scanning information on a water ring origin point (water-ring (0)) in an image frame, which is a most significant bit of the image frame to be preferentially scanned; a scan location decision unit for deciding a location of i-th generated water ring (water-ring(i)), which is a rectangular-shape ring surrounding the water ring origin point; and a scan unit for scanning information on the location of the i-th generated water ring.

摘要： Provided are a method and an apparatus for improving resolution in comparison with lowering resolution of an original image and increasing a compression rate in comparison with directly compressing an original image based on information of the original image. The method includes the steps of subtracting a pixel value of a reference image from a pixel value of an image to be encoded to thereby create a residue signal, lowering resolution by down-sampling the residue signal, and encoding the down-sampled residue signal.

摘要： A method of and apparatus for encoding and decoding a signal by illumination change compensated motion estimation are provided. The apparatus for encoding a signal by illumination change compensated motion estimation includes: an illumination change compensation unit performing compensation for an illumination change by performing a differential calculation between each pixel value of a current block and the means pixel value of a reference block indicated by a motion vector of the current blok and the mean pixel value of the reference block; a residual signals generation unit generating redisual signals based on the blocks in which illumination change compensation is performed; and an illumination changed amount prediction unit performing differential pulse code modulation (DPCM) based on the illumination change amount prediction value by reflecting the closeness between neighboring blocks in which illumination change occurs.
