Zusammenfassung:	PURPOSE:To reduce high frequency components in a binary data dot shape by rescanning a binary image signal with a scanning window of 5X5 picture elements and changing the value of a center picture element and the value of a contiguous picture element when the center picture element is the high frequency component and plural picture elements having the same value are detected outside the contiguous picture element having different values. CONSTITUTION:A high frequency element decision circuit 11 outputs '1' when there is
