ABSTRACT:
Input bit map image data having a resolution of 600 dpi is converted into multivalue image data MI having a resolution of 600 dpi by a binary-to-multivalue converting unit. The multivalue image data MI is converted into multivalue image data having a resolution of 400 dpi by a resolution converting unit. The edge direction of the multivalue image data is detected by an edge direction detecting unit, so as to obtain an edge direction detection flag. Based on the edge direction detection flag, an image data outputting unit outputs multivalue image data having a resolution of 400 dpi from the edge direction detecting unit.
