Claim 15:
16. A video image processing device comprising:
a processor; and
a memory storing program instructions that, when being executed by the processor, cause the processor to:
binarize a chrominance prediction mode of an image block of a to be encoded or decoded image to obtain a bit string, the bit string including at least two adjacent bits, the to be encoded or decoded image being permitted to use at least one of a cross-component linear model (CCLM) or a regular intra-frame chrominance prediction mode, the CCLM including at least a first mode, a second mode, and a third mode, the regular intra-frame chrominance prediction mode being other intra-frame chrominance prediction mode expect the CCLM, wherein:
a first bit of the adjacent bits is used to indicate whether the CCLM is used, the second bit is used to indicate whether to use the first mode of the CCLM when the first bit indicates to use the CCLM, the third bit is used to indicate whether the second mode or the third mode of the CCLM is used when the second bit indicates that the first mode of the CCLM is not used; and
use mutually independent probability models to respectively encode or decode the second bit and the third bit.
