Method for tracing an object |
摘要 |
A method for tracing an object such as an outline of a picture or a line image, wherein the object is sensed by a set of sensing elements arranged in an optical head moving along the object, to detect a position and a direction of the object, wherein the optical head is controlled to trace the object depending on the detected position and the direction of the object, and wherein the object is reproduced by reproduction means which is moved in synchronization with the optical head. Present invention improves this method by moving the optical head along portions of the object, which the sensing elements can discriminate hardly or not at all nor follow the object, according to line segment data which is predetermined and represent a plurality of points of coordinates.
