20090231634 | IMAGE DRAWING APPARATUS AND METHOD - In an image drawing apparatus which performs N-tuple image drawing, an image drawing head is mounted so that the pixel column direction of two-dimensionally arranged usable pixels and a scan direction of the image drawing head with respect to an image drawing surface form a predetermined set inclination angle. A pixel-to-utilize setting unit sets, based on variance in the inclination angles of pixel columns with respect to the scan direction, pixels-to-utilize, which are utilized in N-tuple image drawing, to operate among a great number of usable pixels. The pixel-to-utilize setting unit includes a pixel-to-utilize designation unit, a setting changing unit or the like. An image is drawn on the image drawing surface by causing the pixels-to-utilize, designated by setting, to operate while the image drawing head is relatively moved with respect to a stage. | 09-17-2009 |
