Abstract

An optical cutting image which has a maximum portion in the X-axis direction on the screen of an image sensing device and which extends in the X-axis direction away from the maximum portion so as to expand in the Y-axis direction is measured by means of plural windows to be set on both side portions of the image as seen in the Y-axis direction, equations to represent the image lines of both side portions, and the like. The position of a front end point of the image is measured. A first window which is oblong in the X-axis direction is set such that the front end point is contained therein. A position of the center of gravity of image inside the first window is measured. Second and third windows which are oblong in the Y-axis direction are set at a position which is backwardly away by a predetermined length from the center of gravity of image inside the first window in the X-axis direction to measure the position of the center of gravity of image inside each of the windows. A reference point which has a predetermined correlation with the centers of gravity of image inside the second and third windows is obtained. The above-mentioned plural windows are respectively set in a predetermined positional relationship with this reference point.
