Publication number: 20120327189Abstract: A stereo camera apparatus which carries out distance measuring stably and with high accuracy by making measuring distance resolution variable according to a distance to an object is provided. A stereo camera apparatus 1 takes in two images, changes resolution of a partial area of each image that is taken in, and calculates a distance from a vehicle to an object that is imaged in the partial area, based on disparity of the partial area of each image in which resolution is changed. Thus, even when the object exists at a long distance and is small in size, distance measuring processing can be carried out stably.Type: ApplicationFiled: August 13, 2010Publication date: December 27, 2012Applicant: Hitachi Automotive Systems, Ltd.Inventors: Shoji Muramatsu, Mirai Higuchi, Tatsuhiko Monji, Soichiro Yokota, Morihiko Sakano, Takeshi Shima

Patent number: 7989330Abstract: After etching a polysilicon film, when a protective film made of a carbon polymer is formed on a sidewall of the polysilicon film using plasma containing carbons, a metallic material as a lower film is etched using plasma containing a halogen gas under an etching condition in which volatility is improved due to the rise in a wafer temperature or the low pressure of a processing pressure, thereby preventing a side etching and unevenness of a sidewall of the polysilicon film. Further, by using the protective film made of a carbon polymer, metallic substances scattered at the time of etching the metallic material are not directly attached to the polysilicon film, but can be simply removed along with the protective film made of a carbon polymer in an asking step.Type: GrantFiled: July 30, 2009Date of Patent: August 2, 2011Assignee: Hitachi High-Technologies CorporationInventors: Takeshi Shima, Kenichi Kuwabara, Tomoyoshi Ichimaru, Kenji Imamoto

Patent number: 7957559Abstract: In conventional systems using an onboard camera disposed rearward of a vehicle for recognizing an object surrounding the vehicle, the object is recognized by the camera disposed rearward of the vehicle. In the image recognized by the camera, a road surface marking taken by the camera appears at a lower end of a screen of the image, which makes it difficult to predict a specific position in the screen from which the road surface marking appears. Further, an angle of depression of the camera is large, and it is a short period of time to acquire the object. Therefore, it is difficult to improve a recognition rate and to reduce false recognition. Results of recognition (type, position, angle, recognition time) made by a camera disposed forward of the vehicle, are used to predict a specific timing and a specific position of a field of view of a camera disposed rearward of the vehicle, at which the object appears.Type: GrantFiled: July 13, 2007Date of Patent: June 7, 2011Assignee: Hitachi, Ltd.Inventors: Takeshi Shima, Shoji Muramatsu, Yuji Otsuka, Kimiyoshi Machii, Mirai Higuchi, Tatsuhiko Monji, Kota Irie
