Title:
ADAPTIVE-WEIGHTED MOTION ESTIMATION METHOD AND FRAME RATE CONVERTING APPARATUS EMPLOYING THE METHOD
Document Type and Number:
WIPO Patent Application WO/2005/109897
Kind Code:
A1
Abstract:
An adaptive- weighted motion estimation method and a frame rate converting apparatus employing the method are provided. The method includes estimating a global motion vector by a correlation between frames, and calculating a block matching value between the frames according to a weight value where the estimated global motion vector is applied and determining a lowest block matching value to be a motion vector.
