A DRIVING APPARATUS OF PLASMA DISPLAY PANEL, A METHOD FOR PROCESSING PICTURES ON PLASMA DISPLAY PANEL AND A PLASMA DISPLAY PANEL

摘要

The present invention relates to an image processing method of reducing false contour and a driving device and a plasma display panel capable of high-speed operation is a plasma display panel. First, it separates each frame of an input video signal into at least two independent frame parts. Thereafter, at least two independent parts separated frame data is determined whether or not whether or not the motion image in each edge region that determines the degree of false contour generated. At this time, in a different false contour generation level pseudo outline the current input the independent partial frame data gradation conversion range is to be reduced, depending on, if a lot of false contour is to increase the gradation conversion range to convert so that it is similar in the light emitting pattern. In addition, each for using a result of the gradation transformation applying the error diffusion for each of at least two independent frame parts are applied to the diffusion errors into the error, which are mutually mixed partly spread. Through this, a pseudo contour can be reduced still more precise, this is a high speed error diffusion process and the high-frequency component in the data of the number of pixels in the image display apparatus of high resolution can be improved to provide an image of improved quality. ; PDP, pseudo contours, edges, grayscale conversion, even, odd
