PURPOSE:To perform smooth interpolation by solving lack of continuity of a character or a figure when original pixels are doubled as they are in 100-to-200 dpi enlargement line density conversion. CONSTITUTION:This system has a (m)-line, (n)-column window memory part which stores binarized data to be processed, and a center point is set at a reference pixel (p); and data of four pixels in two lines and two columns are processed by a logical arithmetic part 2 from the reference pixel (p) and its peripheral pixels to a reference pixel point and outputted to an arithmetic output part 3. When the reference pixel P is set at all points on an original image, an image which is doubled in a main scanning and a subscanning direction is obtained. Therefore, the logic of the logical arithmetic part 2 of this system is altered to easily obtain an image whose outline is smooth. |
