ABSTRACT:
A discriminator is provided in a driving system for a plasma display panel so as to discriminate whether an input video signal is a moving picture signal or a still picture signal, and an A/D converter is provided for sampling the video signal for producing a pixel data having n-bit. The pixel data is converted into a false contour correcting pixel data having a (n+m)-bit based on a correcting pixel data derived from a table. A controller selects the false contour correcting pixel data when the input video signal is a moving picture signal, and selects the pixel data from the A/D converter when a still picture signal. The plasma display panel is driven by a pixel data determined by the controller.
