METHOD FOR FRAME RATE UP-CONVERSION CONSIDERING THE DIRECTION AND MAGNITUDE OF MOTION VECTORS AND APPARATUS USING THE SAME

摘要

A frame rate increasing method considering the direction and magnitude of motion vectors and an apparatus using the same are disclosed. The method of increasing a frame rate may include: determining whether a previous frame or a current frame is a dynamic frame or a static frame using an average motion vector magnitude in at least one direction of a current frame and a previous frame after bidirectional motion prediction; Directional motion prediction for a previous frame or a current frame, the direction of motion vectors detected in each of the sub-pixels in the mask of a certain size among the sub-pixels of the block generated in the extended bidirectional motion prediction, Determining whether the sizes of the motion vectors are the same within a predetermined error range if the directions are the same, and if the sizes are the same, generating between the previous frame and the current frame To be a block of intermediate frames And omitting motion vector smoothing for the motion vector.
