Representative points are added to peripheral pixels in every black pixel groups. The thus generated representative points are joined by a curve-fitting approximation method to obtain an outlined curve for every black pixel group. One pixel is divided into a multiple number of sub-pixels. Pulse signals supplied to a laser is modulated on pulse width so that the sub-pixels (hatched section) belonging to the inside of each curve may be exposed to laser beams.
