1. A frame interpolation method for generating a third image frame interpolated between a first image frame and a second image frame, comprising:
performing motion estimation upon a first input image frame and a second input image frame, to obtain a single-directional motion, wherein the first input image frame is derived from the first image frame, and the second input image frame is derived from the second image frame;
scaling the single-directional motion according to a time point of the third image frame, to generate a scaled motion;
deriving a forward-warped result from a result of performing a forward warping operation and a first inverse operation upon the scaled motion;
performing a second inverse operation upon the forward-warped result, to generate an inversed result; and
generating the third image frame according to the first image frame, the second image frame, the forward-warped result, and the inversed result.
