Patent number: 6649904Abstract: A subject-state detecting apparatus has an active distance measuring sensor including projectors for targeting measurement regions independently, and a photodetector for detecting reflection light reflected from a subject that receives light projected by the light projectors. A measurement parameter decision section decides in advance a body parameter to be measured. In response to the parameter, a distance measuring sensor setting section sets a measurement region of the active distance measuring sensor and an additional distance measuring sensor. A state decision section decides state of the subject from the outputs of these sensors.Type: GrantFiled: June 12, 2002Date of Patent: November 18, 2003Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Kentaro Hayashi, Manabu Hashimoto, Kazuhiko Sumi

Publication number: 20020191819Abstract: The present invention provides the image processing apparatus having a function of detecting a wheelchair passenger. This image processing apparatus comprises a TV camera installed so that a hall where passengers are waiting is monitored through the camera provided in the vicinity of the elevator door, a face area extraction unit, a wheelchair area estimation unit, and a wheelchair existence judgment unit. The image processing apparatus is operated in the following manner, that is, one or a plurality of passengers' face area is identified by the face area extraction unit based on the image picked-up by the TV camera, and the position of the face area on the image is detected. If the passenger is sitting on a wheelchair, the area where the wheelchair is likely to exist on the image is estimated by the wheelchair area estimation unit from the position of the face area.Type: ApplicationFiled: July 3, 2002Publication date: December 19, 2002Inventors: Manabu Hashimoto, Kazuhiko Sumi

Publication number: 20010026347Abstract: A liquid crystal display device of the present invention has a structure in which vertically aligned liquid crystal is sealed between a TFT substrate and a CF substrate. Pixel electrodes in which slits are provided are formed on the TFT substrate, while cell gap holding spacers and domain defining projections are formed on the CF substrate. For example, positive type photoresist is coated on a common electrode. Then, first exposure is executed by using a mask for light-shielding spacer forming regions and projection forming regions, and then second exposure is executed by using a mask for light-shielding the spacer forming regions. Then, the photoresist is developed. Accordingly, the spacers and the projections, each having a different height, can be formed simultaneously.Type: ApplicationFiled: January 12, 2001Publication date: October 4, 2001Applicant: FUJITSU LTD.Inventors: Manabu Sawasaki, Takashi Takagi, Yoji Taniguchi, Hiroyasu Inoue, Susumu Nakano, Tomonori Tanose, Naonobu Matsui, Kazuyuki Hosokawa, Kazuhiko Sumi, Masahiro Ikeda, Naoshige Itami

Patent number: 5652938Abstract: A resist developing apparatus has a plurality of developing solution containers each provided with a temperature regulator, a mixture tank connected to the plurality of developing solution containers, a flow control valve connected between the mixture tank and each developing solution container, a temperature detector for detecting the temperature of developing solution in the mixture tank, and a control system for controlling the flow control valve in accordance with the temperature detected by the temperature detector. As the development progresses, the temperature of the developing solution is lowered to stop the development. Thereafter, the developing solution is supplanted by rinsing solution.Type: GrantFiled: June 21, 1996Date of Patent: July 29, 1997Assignee: Fujitsu LimitedInventors: Masahiro Uraguchi, Yusei Miyazono, Kazuhiko Sumi

Patent number: 5625717Abstract: An image processing device includes: a DOG filtering means for applying a DOG filter upon the grey level image of an object; and a tri-level thresholding means for thresholding the output of the DOG filtering means at two distinct threshold levels, thereby obtaining a tri-level image of the object. The 0-level regions of the tri-level image correspond to regions of the original image, such as the surface areas of the object, within which the variation of the grey level is small. The boundary between two 0-regions is marked by adjacent parallel strips of a (+)-region and a (-)-region, wherein the zero-crossing line between the (+)-region and the (-)-region clearly defines the contour line of the 0-regions. This method of tri-level quantization provides a basis for efficient template matching of the images of objects, recognition or identification of objects, the detection of movement vectors of objects, and the detection of the parallax of a continuously moving objects.Type: GrantFiled: June 22, 1993Date of Patent: April 29, 1997Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Manabu Hashimoto, Kazuhiko Sumi
