Abstract
PURPOSE:To realize the pre-processing operation so that the interruption, etc., can be recovered and a picture turned into thin lines can be obtained at high speed, by retrieving the erasable picture elements out of eight picture elements at most near the picture element that is extended last and then erasing those retrieved picture elements. CONSTITUTION:A picture element X is the last one of those picture elements added for connection in a step S7 and the picture elements (a-e) are set adjacent to the element X. Under such conditions, it is decided in a step S8 whether the points (a-e) are all equal to black picture elements or not. If so, the connecting one of points (a), (b) and (e) is erasable and deleted in steps S9 and S10. If not, the operation proceeds to a step S14. Then it is decided whether both picture elements (b) and (c) are equal to black picture elements or not. If so, the point (e) is erasable and deleted in a step S16 as long as the point (e) serves as a connecting point. Thus a line is extended and some of eight picture elements near the last added point are checked. Then the erasable points are deleted. As a result, the pre-processing time is shortened and a recovered picture can be turned into thin lines at high speed.
