Patent number: 5638465Abstract: An image of a part is used to judge whether it is good or no good. A predetermined intensity, edge or similar feature image is extracted from the inspected image and is quantized. The quantized feature image is obtained from a training image in advance, and the feature is subjected to a generalized Hough transform operation which refers to the weight of each feature point for each feature value in the image and vote the feature point weight. The similarity is obtained from the results of the transform operation, and a good/no good judgement is made depending upon whether the similarity is above or below a threshold value.Type: GrantFiled: June 9, 1995Date of Patent: June 10, 1997Assignee: Nippon Telegraph and Telephone CorporationInventors: Mutsuo Sano, Masashi Okudaira, Eiji Mitsuya, Joji Sahashi, Hisao Kuroda, Shuichi Ohara

Patent number: 5157526Abstract: The polarizer of the present invention is composed of mediums having different refractive indices, by which ordinary light in incidented light is wholly reflected at a boundary between laminated medium I and medium II and extraordinary light is transmitted through the medium II. The medium II is so arranged as to be almost 45.degree. to the light axis, and thickness of the medium II is selected as a value with which the medium II works as a half wave length plate to the transmitting light. The polarizer, which has high transparency by reduction of absorption and is able to make most of incident light be similarly polarized light, is obtained. A polarizer for and apparatus for bright liquid crystal display, which is able to be enlarged to a large size display without light absorption, can be provided.Type: GrantFiled: July 1, 1991Date of Patent: October 20, 1992Assignee: Hitachi, Ltd.Inventors: Katsumi Kondo, Junichi Hirakata, Osamu Ito, Teruo Kitamura, Shuichi Ohara, Naoki Kikuchi, Masato Shimura
