摘要： A moving picture coding apparatus divides a picture into basic blocks and generates a prediction image of a block to be predicted in a basic block by using adjacent pixels in reference pixel blocks adjacent to the block to be predicted as reference pixels to perform predictive coding of a moving picture. When some of the reference pixels are not available, pixel values of the reference pixels that are not available are calculated based on pixels in the reference pixel blocks. The prediction image of the block to be predicted is generated by using the calculated pixel values instead of the reference pixels that are not available.

摘要： Disclosed is a video encoding and decoding device which encodes images and compresses the information volume in accordance to the standard H.264. In the device, image folding determination processing is performed utilizing the symmetry of an input image, and a block of one area of the input image is set to be a folding area. By setting folding points describing the folding area, only information for the folding area and the folding points is encoded. After decoding, the entire image is restored from the folding area, which was the encoded area, but in areas that cannot be directly restored from the folding area, the image is restored by performing padding from peripheral blocks. By this means, the symmetry of an image is utilized to increase encoding efficiency without degrading image quality.

摘要： Suppression of prediction error accumulating in an intra prediction is described. A motion picture encoding apparatus that performs encoding processing for each pixel block using a motion picture encoding method includes intra prediction processing for generating a prediction image using correlation of pixels therearound, and in the intra prediction processing, the motion picture encoding apparatus has processing for generating a quasi-prediction image from an input image, wherein when a prediction mode is determined, a weight is given to a pixel serving as a reference pixel in the intra prediction processing, and thus, the prediction mode is determined. When the weight is set at one or more, an error of a pixel serving as a reference pixel in a subsequent block is emphasized, and therefore, a prediction mode that is likely to propagate the error to the subsequent block is less likely to be selected.
