摘要： In a display method of a PDP apparatus or the like, there is provided a technique for reducing or eliminating dynamic false contours in a display video image by determining and detecting an occurrence region of dynamic false contours in display data with good accuracy for coping. In a false-contour detection unit in a PDP apparatus, a carry detection unit detects, as a dynamic-false-contour occurrence region, a pixel region corresponding to carry in an SF on-cell pattern of adjacent pixels based on a video image signal in view of a predetermined condition. In a width control unit, a detection region is expanded according to a motion amount. A detection region is expanded according to a motion amount in a width control unit. A diffusion processing (actual gray-scale number restriction processing) based on dither or error diffusion is performed to the detection region. A detection condition of the carry is that an on-cell state of an SF with higher weighting is different between the adjacent gray scales sandwiching the carried gray scale therebetween.
