Motion compensation apparatus having at least one processing circuit shared by normal mode and resized reference frame mode and related motion compensation method

Abstract

A motion compensation apparatus includes an interpolation filter device, a pixel fetching circuit, and a pixel dispatching circuit. The interpolation filter device generates interpolated pixels by performing interpolation according to reference pixels. The pixel fetching circuit fetches the reference pixels from a reference frame. The pixel dispatching circuit dispatches pixels to the interpolation filter device, wherein the pixels comprise the reference pixels. At least one of the interpolation filter device, the pixel fetching circuit and the pixel dispatching circuit is shared by a normal mode and a resized reference frame (RRF) mode of motion compensation.
