Abstract: In an on-screen display (OSD) image processing method for generating an interpolated frame with interpolated blocks, motion compensation is performed to generate motion compensation (MC) data according to a first motion vector referring to a previous frame and a second motion vector referring to a current frame. Zero-motion data are generated according to a zero-motion vector referring to the previous frame and the current frame. The MC data of a first weight and the zero-motion data of a second weight are blended to generate each interpolated block as a processed block. When the number of pixels having OSD data in the processed block is less than a first positive threshold and larger than a second positive threshold, the processed block is determined as an extended OSD block and the second weight of the extended OSD block is less than that of an OSD block.
