MOTION VECTOR DETECTION METHOD AND DEVICE, PLASMA DISPLAY PANEL DRIVING METHOD, AND PLASMA DISPLAY DEVICE

摘要

A method for detecting a motion vector (?,?)1n between previous and next frames (SF) of a moving picture which is displayed on a screen (10) having pixels (11) that are arranged in matrix. The method is characterized in that the detection area for detecting the motion vector is arranged in a plurality of layers on the screen so that a low order detection area is included in the high order detection area; with respect to each of the detection areas in the plurality of layers, Fourier transform of the previous frame Fmn(u,v) and that of the next frame F'mn(u,v) are obtained and motion vector information ?mn(k,1) is calculated; and the motion vector in the lowest order detection area is decided from the lowest order detection area and the average of the motion vector information detected in the plurality of high order detection areas including the lowest order detection area among the detection areas in the plurality of layers.
