FIELD: movement estimation, in particular, estimation of movement on block basis in video image compression application.
SUBSTANCE: method and device are claimed for conducting search for movement in video encoder system using movement vectors which represent difference between coordinates of macro-block of data in current frame of video data and coordinates of corresponding macro-block of data in standard frame of video data. A set of movement vector prediction parameters is received, where movement vector prediction parameters represent approximations of possible movement vectors for current macro-block, movement vector search pattern is determined and search is conducted around each movement vector prediction parameter from the set of movement vector prediction parameters using search pattern, and on basis of search result, the final movement vector is determined.
EFFECT: increased efficiency of video signals compression.
