A three-times magnified pattern of a central target pixel and horizontally contiguously adjacent sub-pixel patterns next thereto are determined on the basis of a reference pattern that has a rectangular profile and further that consist of eight-neighboring pixel about the target pixel. The determined three-times magnified pattern is allocated to three sub-pixels that form the target pixel.
