Abstract
The controller unit 2a can perform in a color extraction mode and a marker processing mode. The color extraction mode is a mode in which an image within the range of a particular color is extracted and reproduced in that color. In the marker processing mode, an area surrounded by a color marker is detected and a prescribed processing is performed for an image in that area. A main-scan smoothing circuit 130 changes the number of pixels or the weighting coefficients used in smoothing in accordance with above described modes.
