METHOD AND APPARATUS OF PROCESSING VIDEO DATA FOR PLASMA DISPLAY PANEL

摘要

The present invention relates to a method and apparatus for processing digital video data, and more particularly, to a method and apparatus for processing video data in a plasma display panel, wherein contour noise can be reduced. The method of processing the video data in the plasma display panel in which the number of bits of the video data is reduced through an error diffusion method and a dithering method includes the steps of performing a confined error diffusion process on inputted video data within the range of dither mask patterns of an upper gray scale, and dithering the confined error-diffused video data using a plurality of dither mask patterns that are separated on a gray scale and frame basis.
