Abstract:
A prediction set determining section selects a prediction set from a prediction set group including a plurality of prediction sets having different combinations of prediction modes corresponding to different prediction directions. Further, a prediction mode determining section selects a prediction mode from the prediction set thus selected. An entropy encoding section encodes the prediction set thus selected, the prediction mode thus selected, and residual data between an input image and a predicted image formed on the basis of the prediction set and the prediction mode. This allows an image encoding device to carry out predictions from more various angles, thereby improving prediction efficiency.

Claim (Index 1):
An image decoder for decoding encoded image data, the image decoder comprising a processor and a memory, the processor, working together with the memory, being configured to:\n decode, from the encoded image data,\n (i) at least one syntax element for deriving a first parameter, the first parameter being indicative of a plurality of predefined prediction modes, wherein the plurality of predefined prediction modes includes at least one directional mode, \n (ii) a second parameter for identifying a prediction mode of the plurality of predefined prediction modes, and \n (iii) residual data for each block of a plurality of blocks to be intra-predicted; \n derive, using the at least one syntax element, the first parameter; select, using the first parameter and the second parameter, one prediction mode from the plurality of predefined prediction modes; generate, using the selected prediction mode, a predicted image of at least one block of the plurality of blocks to be intra-predicted; and generate a decoded image of the block by adding the predicted image of the block and the residual data for the block.
