Abstract: An image processing method for a video processor, for generating an extrapolated frame according to a previous frame and a current frame, includes steps of: projecting a plurality of motion vectors (MVs) to the extrapolated frame subsequent to the current frame; determining whether a block of the extrapolated frame is projected by at least two of the MVs; selecting at least two candidate MVs from the MVs projected to the block when the block is projected by at least two of the MVs; calculating a blended MV which is a mixture of the at least two candidate MVs, and projecting the blended MV to the previous frame; obtaining a reference MV corresponding to position of the previous frame projected by the blended MV; and comparing the reference MV with the at least two candidate MVs, to select a final MV for the block from the at least two candidate MVs.

Abstract: An image processing method for a video processor for generating an interpolated frame includes steps of: receiving a segmentation map comprising a plurality of segmentation flags; generating an original motion vector (MV) for a first block of the interpolated frame; 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.

Abstract: A frame rate up-conversion (FRC) apparatus and an operation method thereof are provided. A motion vector (MV) generation circuit provides an MV of a current pixel of an interpolation frame. According to the MV, a data fetch circuit fetches first original data of a first pixel in a first original frame and second original data of a second pixel in a second original frame. According to a position of the first pixel in the first original frame and a position of the second pixel in the second original frame, a boundary processing circuit processes the first original data and the second original data to generate first processed data and second processed data. An interpolation frame generating circuit generates pixel data of the current pixel of the interpolation frame according to the first processed data and the second processed data.
