Abstract: An intra prediction unit is a device for performing intra predictions compliant with a specified picture coding standard, and comprises n prediction processing units that perform a parallel processing of the intra predictions, where n is an integer larger than one. Each of m prediction modes excluding at least, one prediction mode among a plurality of prediction modes defined in the specified picture coding standard is allocated to one of the n prediction processing units, where m is an integer larger than one. Each of the n prediction processing units performs an evaluation processing for the allocated one or more prediction modes to evaluate which prediction mode is to be selected among the m prediction modes.

Abstract: Provided is an image coding method which obtains a picture, and codes the obtained picture. The image coding method generates a processing block, performs a first intra prediction that selects one intra prediction mode from a first set of candidates based on a component of a first signal contained in the processing block, performs a second intra prediction that selects one intra prediction mode from a second set of candidates based on a component of a second signal contained in the processing block. The first set of candidates includes a plurality of intra prediction modes, and the second set of candidates includes an intra prediction mode, having no dependency between the second intra prediction and the first intra prediction, of the plurality of intra prediction modes. The first intra prediction and the second intra prediction are performed in parallel.
