Abstract:
A predicted image is generated by means of a method with which it is easy for parallel processing for a plurality of pixels to be executed, in a case where each pixel of the predicted image is derived according to a distance from a reference region and with reference to an unfiltered reference pixel. A predicted pixel value constituting the predicted image is derived by applying weighted sum in which a weighting coefficient is used with respect to a filtered predicted pixel value in a target pixel within a prediction block, and at least one or more unfiltered reference pixel values, and the weighting coefficient for the unfiltered reference pixel values is derived as a product of a reference intensity coefficient that is determined according to a prediction direction indicated by a prediction mode, and a distance weighting that monotonically decreases according to an increase in a reference distance for the target pixel.

Claim (Index 12):
A video image coding device, in an image coding device that generates coded data from a video image by generating a predicted image with a prediction block serving as a unit in accordance with an intra-prediction method associated with a prediction mode, comprising:\n a filtered reference pixel setting circuit that derives a filtered reference pixel value in a reference region that is set with respect to the prediction block; an intra-prediction circuit that derives a filtered predicted pixel value of the prediction block with reference to the filtered reference pixel value in accordance with a prediction method corresponding to the prediction mode; and a predicted image correction circuit that generates the predicted image from the filtered predicted pixel value by carrying out predicted image correction processing on the basis of an unfiltered reference pixel value in the reference region and the prediction mode, wherein the predicted image correction circuit derives a predicted pixel value constituting the predicted image by applying weighted sum in which a weighting coefficient is used with respect to the filtered predicted pixel value in a target pixel within the prediction block, and at least one or more unfiltered reference pixel values, and the weighting coefficient for the unfiltered reference pixel values is a product of a reference intensity coefficient that is determined according to a prediction direction indicated by the prediction mode, and a distance weighting that monotonically decreases according to an increase in a reference distance for the target pixel.
