FIELD: image encoding.
SUBSTANCE: invention relates to the field of image encoding technologies, in particular to devices for video image prediction.Video images prediction equipment contains: a syntactic analysis unit configured for syntactic analysis, from a sequence parameter set (hereinafter – SPS) in a bit stream, of a value of the first sps_affine_enabled_flag indicator and a value of the third sps_sbtmvp_enabled_flag indicator; wherein the syntactic analysis unit is configured for syntactic analysis of a value of the first indicator from the mentioned SPS, when the value of the first indicator is equal to the first value; a determination unit configured for determination of the maximum length of the first list of candidate motion vectors based on the second indicator, when the value of the first indicator is equal to the first value, wherein the first list of candidate motion vectors is a list of candidate motion vectors, created for a block to be processed, a mode of prediction of subblock merge is used for the block to be processed. The determination unit is configured for determination of the maximum length of the first list of candidate motion vectors based on the value of the third indicator, when the value of the first indicator is equal to the second value, wherein the second value differs from the first value.
EFFECT: invention provides determination of the maximum length of a list of candidate motion vectors, corresponding to a subblock merge mode.
