ABSTRACT:
A compressed picture signal having a number of pixels smaller than the number of pixels of an original picture signal is generated, and plural patterns of prediction pixels are formed by using neighboring pixels of as notable pixel which is one of pixels constituting the compressed picture signal. The original picture signal is predicted from each of the plural patterns of prediction pixels and a predetermined prediction coefficient, and each of prediction values with respect to the plural patterns of prediction pixels is outputted. A prediction error of each of the prediction values of the plural patterns of prediction pixels with respect to the original picture signal is calculated, and a pattern code corresponding to a prediction pixel with which a minimum prediction error is obtained, among the plural patterns of prediction pixels, is appended to the pixel value of the notable pixel.
