Abstract
PDP often generates worm-like patterns on a displayed image because it employs an error diffusion method to maintain the quality of the input image by using limited number of gray-levels, which is quite essential for reducing dynamic false contours of PDP. To reduce worm-like patterns of PDP, an adaptive three-dimensional error diffusion method based on interrelation of neighboring frames is proposed. The interrelation of frames is estimated from the difference of adjacent frames, and the amount of quantization error for the spatial and temporal direction is adaptively changed depending on the magnitude of the frame difference.
