A related error Ej obtained previously from several selected pixels. As for respective errors Ej, respectively corresponding weighting coefficients wj are decided. Then, the obtained gray value Ri of the focus pixel is calculated by Ri=Gi+Σwj(Ej-C), (wherein, C is the programmable integer). After than, the value Ri is divided into the highest order part Mi and the lowest order part Li. In this case, Mi is K-bit integer, Li is (N-K) bit integer, Mi×2N-K+Li=Ri and -2N-K/2<=Li<N-K/2. The error Ej of the focus pixel is stored as a value obtained by adding Li and 2N-K/2 being an error bias D. Finally, the focus pixel is displayed as a deteriorated target gray value by using Mi.
