Abstract
A method of and an apparatus for converting a frame rate using time shifting and motion compensation. The frame rate converting method includes calculating an average motion vector magnitude between every two adjacent frames among a predetermined number of frames input in series determining a frame section corresponding to a maximum value among the average motion vector magnitudes calculated every two adjacent frames and generating a new frame by performing motion compensation, to which a predetermined proportion is applied, in the frame section having the maximum motion vector.
