An image signal generating system has a contour drafting control portion. The portion generates contour points of a predetermined character on the basis of character information. It also writes contour information of the generated contour points in corresponding storage portions of a work memory per a drafting effective region. Further, the portion updates a value stored in the storage portion of a counter table at a corresponding position in the Y-direction to the contour point when a contour point to be present in another drafting effective region is positioned at a raster scanning starting side in the X-direction with respect to the drafting effective region currently processed. There is also a painting processing portion for scanning the work memory per one line in the X-direction, and updating a value of the storage portion of the counter table corresponding to the scanning line and generating painting data for the area where the value of the counter table is other than "0".
