ABSTRACT:
A line image processing method for processing an image in which the following line or lines defectively and dispersedly exist in a line image to be shaped: a line which is connected to a line which should be disconnected therefrom to make a long line or make a branch line, lines which should connected to each other and which are separated from each other, a line which is connected to an unnecessary short line, or a line which has a short line connected thereto indicating noise, includes the steps of picking up a line image to be processed by an image pick-up device, scanning the line image to retrieve a line to be traced, tracing an arrangement direction of each pixel composing the retrieved line by means of a direction code, tracing the retrieved and traced line to an end point thereof by selecting at a branch point a direction closer to an average value of a plurality of various direction codes preceding the branch point when the branch point is detected, erasing an image of a cluster corresponding to the line traced to the end point thereof from the line image to be processed, transferring image data of the cluster to a different processed line image, tracing all lines by repeating the above steps, erasing the image data of the cluster from the line image to be processed, and transferring the generated image data of the cluster to the processed line image.
