Abstract
In this study, a method for reducing the dynamic-false contour (DFC) in POP is proposed. First, the moving pixel distortion (MPD) values are calculated for the whole image. Then, the image is divided to the fixed square blocks and the mean MPD value of the blocks is calculated, and the chessboard pattern is added to the blocks to be processed. The pattern strength is modified according to the mean MPD value of each block. The pattern strength is limited and the patterns for odd and even frame are made to be opposite with each other to lessen the visibility of image modulation. The chessboard pattern is effective for scattering DFC and changing DFC strength, causing the DFC visibility to be greatly reduced. The newly proposed method is independent of the motion and does not require expensive calculation.
