FIELD: physics, computer engineering.
SUBSTANCE: invention relates to computer engineering. The image processing device comprises a module for calculating residual energy in spatial mode, configured to use motion vector information according to a spatial motion prediction mode for a target unit using a peripheral pixel situated adjacent to the target unit in a given position ratio with said unit and also included in a decoded image; a module for calculating residual energy in temporal mode, configured to use motion vector information according to a temporal motion prediction mode for the target unit using said peripheral pixel; and a module for determining a motion predictive coding mode, configured to determine that target unit coding should be performed in spatial motion prediction mode if residual energy in the spatial mode is not greater than residual energy in the temporal mode, and determined that target unit coding should be performed in temporal motion prediction mode if residual energy in the spatial mode is greater than residual energy in the temporal mode.
EFFECT: high accuracy of prediction.
