METHOD AND APPARATUS FOR ADAPTIVELY CONVERTING FRAME RATE BASED ON MOTION VECTOR, AND DISPLAY DEVICE WITH ADAPTIVE FRAME RATE CONVERSION FUNCTION

摘要

An interpolation image generation method and apparatus for adaptively converting a frame rate based on a motion vector, and a display device having an adaptive frame rate conversion function are provided. The interpolation image generation method includes an interpolation image generation process calculating motion vectors from a previous image unit and a subsequent image unit that are continuous and generating an interpolation image using the motion vectors; a motion error boundary detection process detecting an area, in which a motion error determined from the motion vectors is greater than a predetermined value, as a boundary area of the interpolation image; and a motion compensation process compensating for a motion error inside the detected boundary area based on a dominant direction of the motion vectors using at least one of the previous image unit and the subsequent image unit.
