Abstract
In order to improve coding efficiency, a segmentation circuit performs segmentation of an input picture by clustering referring to distance data calculated from pixel values of the input data, statistic information and a disparity compensated predictive picture, a statistic information calculator calculates an average and dispersion of pixel values of each segment according to pixel values of the input data and segmentation data from the segmentation circuit, a disparity calculator calculates disparity vectors of a horizontal dimension for minimizing error of the disparity compensated picture from pixel values of a reference picture, those of the input picture and the segmentation data, and a disparity compensating predictor generates the disparity compensated predictive picture.
