摘要： PROBLEM TO BE SOLVED: To provide a continuous-sphere detector by which even continuous spheres in different diameters can be detected with high reliability. SOLUTION: The continuous-sphere detector is provided with a mounting part in which a recess capable of housing a sphere is formed on the surface and a detection means comprising a camera by which the sphere housed in the recess is imaged from the upper part of the surface and its tangential direction. The recess is formed in such a way that its bottom face forms a reflecting surface and that its depth becomes smaller than the diameter of the sphere as an object to be detected. The detection means image-processes an image which has imaged the upper part and an image which has imaged the sphere from the tangential direction, and whether the sphere is a continuous sphere or not is judged on the basis of a prescribed logic.

摘要： PROBLEM TO BE SOLVED: To satisfactorily process the unclear circumferential edge image of a low wafer by taking images of a plurality of edges, determining the approximate expression of the edge within the image or the coordinate in a prescribed point on the approximate expression by image processing, and expressing the wafer circumferential part by a numerical expression. SOLUTION: An image processing means 106 has a binarized level setting means, a profile tracking means or the like. The average luminance within a threshold determining area is calculated by the binarized level setting means. The value obtained by multiplying the average luminance by a constant is taken as the initial threshold. In the profile tracking means, the edge detecting area is scanned from the upper right to the left by use of the initial threshold. When a continuation of black picture elements is present after the continuation of a regulated number or more of while picture elements, the boundary between the initial white picture element and black picture element is taken as one point on the edge. In a straight line calculating means, linear expression calculation and abnormal data removing processing are performed. The processing is repeated until conversion is attained. Since the binarized level is regulated to determine the final approximate expression while judging the quality of the approximate expression calculated by the picture element recognized as the edge, the edge can be satisfactorily enciphered.
