FIELD: physics; video.
SUBSTANCE: invention relates to evaluation of motion, particularly to evaluation of motion based on a block in reference to video image compression. The said result is achieved due to that the a method and a device are proposed for determining block conformity quality for a motion vector - candidate in a video encoder system using motion vectors representing difference in coordinates of a data macroblock in the current image data frame and coordinates of the corresponding data macroblock in the standard image data frame. The method involves determination of a search pattern, searching in a region based on the search pattern for a motion vector - candidate for evaluation, calculation of the difference factor, calculation of displacement based on the difference between the motion vector - predictor and the motion vector- candidate, determination of the altered difference factor through summation of the difference factor with displacement, and determination of the resultant motion vector based on the altered difference factor.
EFFECT: improved quality of evaluating motion with relatively low complexity.
