The method of reduce immoderate phenomenon of an image expression apparatus

摘要

present invention PDP TV to the input image signal of the size and the PDP TV's video output screen size If a different, separate the luminance value of the non-active areas in the case of the block is applied to the main screen, the channel selector when the video is output to the main screen and, in each case varying the brightness value of the video signal output to the non-active areas to relate to minimize transients ways to minimize the PDP TV channel switching transients inactive area by using the ; The invention, 16: 9 aspect ratio with 4 from PDP TV: 3 aspect ratio outputting an image having luminance and to minimize the change in the non-active areas of the case when there is a channel switch to the main screen and the luminance block is hung black screen in the non-active areas of the main screen when the image is written and outputs the user feel to be in the transient which produces the effect of significantly reduced.
