Image processing method based on segmentation map and related video processor

A video processor to generate an interpolated frame having a plurality of blocks according to a previous frame and a current frame by receiving a segmentation map comprising a plurality of segmentation flags, the video processor comprising:

• a motion estimation (ME) circuit to generate an original motion vector (MV) for a first block among the plurality of blocks, and determine 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;
• a vector process (VP) circuit, coupled to the ME circuit, to generate a correction MV for the first block when the ME circuit labels the first block as the segmentation boundary, and determine whether the first block is in a cover area or an uncover area according to the correction MV;
• and
• a motion compensation (MC) circuit, coupled to the VP circuit, to select 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 by the VP circuit.
