Abstract: A moving picture coding method includes partitioning a picture into blocks each of which includes pixels, selecting a scanning scheme from among plural scanning schemes, scanning the blocks according to the selected scanning scheme, and coding the blocks in an order in which the blocks are scanned. In the partitioning, the picture is partitioned into rows and columns of macroblocks each of which is partitioned into the blocks. The plural scanning schemes include a first scanning scheme for scanning the blocks in the marcroblock per row of blocks.

Abstract: An image coding method performs intra prediction with a higher coding efficiency by coding image data on a block-by-block basis. The method generates a predicted block by predicting a current block; computes a difference between the current block and the predicted block; codes the difference computed in the computing; decodes the difference coded in the coding; and adds the difference decoded in the decoding to the predicted block to generate a decoded block. The generating of the predicted block includes detecting an edge in a previously decoded block corresponding to a block adjacent to the current block; and extrapolating or interpolating previously decoded image data corresponding to a pixel included in the block adjacent to the current block, along a direction of the edge detected in the detecting to generate the predicted block.

Abstract: Provided is an image coding method for performing intra prediction achieving higher coding efficiency. The method for coding image data on a block-by-block basis includes; generating a predicted block by predicting a current block; computing a difference between the current block and the predicted block; coding the difference computed in the computing; decoding the difference coded in the coding; and adding the difference decoded in the decoding to the predicted block to generate a decoded block, wherein the generating includes: detecting an edge in a previously decoded block corresponding to a block adjacent to the current block; and extrapolating or interpolating previously decoded image data corresponding to a pixel included in the block adjacent to the current block, along a direction of the edge detected in the detecting to generate the predicted block.

Abstract: The present invention relates to the field of video data de-interlacing, and in particular to a method for reconstructing full-resolution frames from a line-skipped-sequence of fields and a corresponding apparatus. It is the particular approach of the present invention to substitute missing lines of a block of a reconstructed full-resolution frame by lines from another field, e.g. the preceding field, and translating the substitute lines vertically and horizontally so as to optimized a smoothness measure computed for the thus reconstructed block. In this manner, an error-prone a priori determination of motion vectors based an interpolation of the interlaced images in the vertical direction can be avoided. The present invention may also be applied to sequences generated from a full-resolution sequence by a line-skipping operation that keeps only every Kth line and discards the other K?1 lines.

Abstract: The image processing device includes: a specular reflection detector (1110) configured to detect, in a first image, an enlarged region including a saturated region and an adjacent region, the saturated region being a pixel region having a pixel value equal to or larger than a predetermined threshold, and the adjacent region at least partially surrounding the saturated region; and a replacement unit (1130) configured to replace a pixel value of a pixel included at least in the adjacent region, with one of (i) a pixel value of a pixel in a region of a second image that is located at a position corresponding to a position of the enlarged region in the first image and (ii) a pixel value of a pixel adjacent to the pixel in the second image, the adjacent region being included in the enlarged region detected by the specular reflection detector (1110).
