Summary:It is a purpose for this invention to provide a thinning method for an image for obtaining a resultant image of one pixel width without removing a figure having a line changing the width from 3 pixels to 2 pixels. When this invention defines an index pixel value of unused value in the image, the objective pixel is preserved as it is in the condition that a pixel on one previous scan line along the scan line and to which the pixel corresponding to the objective pixel follows along the scan line is the index pixel, and a pixel on latter scan line and which the pixel corresponding to said objective pixel is in front of along the scan line is the background pixel.
