<P>PROBLEM TO BE SOLVED: To appropriately extend the length of a line segment based on characteristics of an object or the scanning speed of laser light to improve drawing quality. <P>SOLUTION: A laser drawing device includes: a laser device for emitting a laser beam; a movable mirror for deflecting the laser beam; an end point shifting unit for obtaining a data group of line segments of single stroke drawing representing the shape of an object to be drawn by one or a plurality of parts of single stroke drawing, and shifting end points of the each part of one stroke drawing except for intermediate points outwardly along extended lines of the line segment including end points by an end point shifting amount calculated based on a laser scanning speed included in the data group of line segments of single stroke drawing; a drawing instruction generating unit for generating a drawing instruction based on the data group of line segments of single stroke drawing after the end points have been shifted; and an illuminator for actuating the movable mirror and irradiating an object on which an image is drawn with the laser beam based on the generated drawing instruction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
