1. An image processing method for a video processor, for generating an interpolated frame having a plurality of blocks according to a previous frame and a current frame, the method comprising:
receiving a segmentation map comprising a plurality of segmentation flags;
generating an original motion vector (MV) for a first block among the plurality of blocks;
determining whether to label the first block as a segmentation boundary according to the plurality of segmentation flags in an area corresponding to the first block;
generating a correction MV for the first block when the first block is labeled as the segmentation boundary;
determining whether the first block is in a cover area or an uncover area according to the correction MV; and
selecting a final MV for a specific pixel of the first block from the original MV and the correction MV according to the segmentation map and according to whether the first block is determined to be in the cover area or the uncover area.
