Abstract:
In a case where a partition mode in which luma signals are partitioned horizontally and vertically is set when an intra prediction of a picture signal is made in units of minimal coding blocks set in advance, an intra prediction unit is configured to make an intra prediction of a chroma signal in units of prediction blocks of the intra prediction of chroma signals within the minimal coding block set in accordance with a chroma format. A second bitstream constructing unit constructs a bitstream of information relating to a luma intra prediction mode of a prediction block of luma signals and information relating to a chroma intra prediction mode of a prediction block of chroma signals.

Claim (Index 3):
A non-transitory computer-readable recording medium having embodied thereon a picture coding program for performing intra prediction coding of a picture signal including a luma signal and a chroma signal in units of blocks and coding information relating to an intra prediction mode, the picture coding program causing a computer to execute:\n an intra prediction step of deriving a value of a chroma intra prediction mode from a conversion table representing a value of the chroma intra prediction mode having a chroma format of 4:2:2 based on a value of a luma intra prediction mode of a prediction block located at a same position as the position of a prediction block of the chroma signal in a case where the chroma format is 4:2:2 and deriving a value of the chroma intra prediction mode based on a value of the luma intra prediction mode of a prediction block located at a same position as the position of a prediction block of the chroma signal without using the conversion table in a case where the chroma format is not 4:2:2, wherein the conversion table shows at least values representing a plurality of chroma intra prediction modes having prediction directions that are respectively closest to a plurality of directions derived by performing \u00bd times scaling horizontally for prediction directions of a plurality of the luma intra prediction modes in which reference destinations are horizontally aligned and the conversion table shows a same unaltered value as a value representing the chroma intra prediction mode as to a value representing the luma intra prediction mode of vertical prediction in which a prediction direction is a vertical direction.
