PATH-BASED INTERPOLATION METHOD FOR FRAME RATE UP CONVERSION (FRUC), AND APPARATUS THEREOF

摘要

According to the present invention, a path-based interpolation apparatus for frame rate up conversion (FRUC) comprises: a processor for receiving source frame information and reference frame information, estimating a unidirectional motion in accordance with a backward path in a case of moving from the source frame information to the reference frame information to generate backward motion vector information, estimating a unidirectional motion in accordance with a forward path in a case of moving from the reference frame information to the source frame information to generate forward motion vector information, recording, in lookup table information, tag information on whether to use a pixel of the backward motion vector information and the reference frame information, or a pixel of the forward motion vector information and the source frame information with respect to pixel positions and pixel values constituting interpolation frame information in accordance with the brightness difference between the pixel of the source frame information and the pixel of the reference frame information corresponding thereto, and generating the interpolation frame information by filling the pixel values of pixels constituting the interpolation frame information in accordance with the tag information recorded in the lookup table information; and a memory unit for providing a storage area of the processor.;COPYRIGHT KIPO 2017
