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

摘要

A PDP image processing method for dividing an image of a field displayed on the PDP into subfields in correspondence to an input image signal, representing gray scales according to combinations of the subfields, and displaying an image corresponding to the image signal. Image signals of a current input frame and a previous input frame are used. A contour noise stage is determined through calculating coding errors and mean gray scale differences. The applicability of the current input image signal to the contour noise stage is determined. Whether to apply dithering is determined. The gray scale of the current input image signal is converted into a gray scale for reducing the contour noise by using dithering, when it is determined to apply dithering.
