Patent number: 7847678Abstract: A vehicle surroundings information output system includes a vehicle surroundings information obtaining mechanism obtaining information about the vehicle surroundings, an object detector detecting an object around the vehicle based on the obtained vehicle surroundings information, an outputting mechanism outputting information relating to the detected object, a detection reliability determining mechanism determining the detected detection reliability of the detected object, and a notifying information generator generating notifying information that relates to that object according to the detection reliability. The notifying information generator is structured to generate notify information that does not easily stimulate at least one of the five senses of a driver when the detection reliability of the object is low as compared to when that detection reliability is high.Type: GrantFiled: September 25, 2006Date of Patent: December 7, 2010Assignee: Toyota Jidosha Kabushiki KaishaInventors: Shinya Kawamata, Yasuo Hagisato

Patent number: 7656423Abstract: An imaging device stores and photoelectric-converts incoming light from an object of which an image is to be captured with a CCD, and controls an output level of a picture signal obtained by signal processing an image signal output from the CCD. An output adjustment value of the picture signal in the output control is set to become 50 to 70 IRE according to a peak value of the picture signal when a test pattern is captured under standard conditions. Accordingly, it is possible to have a typical imaging device display a captured image darker, and thus enable imaging suitable for nighttime imaging and the like.Type: GrantFiled: August 12, 2003Date of Patent: February 2, 2010Assignees: Toyota Jidosha Kabushiki Kaisha, Matsushita Electric Industrial Co., Ltd.Inventors: Yasuo Hagisato, Shinya Kawamata, Ryuji Yamaguchi, Hidetoshi Mimura, Tsuyoshi Kumasaka

Patent number: 7045759Abstract: A second circuit separately extracts a synchronization signal and brightness signal from an image signal output from a camera for capturing an image of a subject. A gamma amplifier produces a gamma correction signal based on a brightness ratio characteristic in which a display brightness increases as the signal level of the brightness signal increases and the display brightness is set using a display brightness correction ratio which is preferably 70 to 90% of an equi-proportional display brightness correction ratio when the signal level of the brightness signal falls in a high-brightness range. A liquid crystal display receives the gamma correction signal and displays an image captured by the camera with the display brightness set in accordance with the brightness ratio characteristic while synchronizing with a drive timing signal output from a first circuit.Type: GrantFiled: February 24, 2003Date of Patent: May 16, 2006Assignees: Denso Corporation, Toyota Jidosha Kabushiki KaishaInventors: Yoshimasa Hara, Shotaro Eguchi, Yasuo Hagisato, Ryuji Yamaguchi, Kunihiko Toyofuku, Shinya Kawamata

Patent number: 6825469Abstract: A vehicle visibility assist device is started up when a switching operation of a switch for an external vehicle light is detected and when it is determined by a brightness sensor that it is darker outside of the vehicle than a predetermined threshold. The visibility assist device projects infrared light to a region outside the vehicle, captures a reflection of the light, processes an image of the region outside the vehicle, and projects the image onto a surface visible to the vehicle operator.Type: GrantFiled: July 29, 2002Date of Patent: November 30, 2004Assignee: Toyota Jidosha Kabushiki KaishaInventors: Ryuji Yamaguchi, Yasuo Hagisato, Kunihiko Toyofuku, Shinya Kawamata

Patent number: 5708413Abstract: Liquid crystal display 1 has a surface disposed in parallel with a surface of holographic concave mirror 2. Liquid crystal display 1 causes a revolution about a display center "d" of holographic concave mirror 2 in a back-and-forth direction as indicated by arrow .alpha.. In response to such revolution around holographic concave mirror 2, liquid crystal display 1 causes an autorotation about its vertical center "e" in the back-and-forth direction as indicated by arrow .beta..Type: GrantFiled: May 17, 1996Date of Patent: January 13, 1998Assignees: Nippondenso Co., Ltd., Asahi Glass Co., Ltd., Toyota Jidosha Kabushiki KaishaInventors: Hideki Okuyama, Yasuo Hagisato, Kohichi Murata, Hiromi Sakurai

Patent number: 4388558Abstract: A display intensity control apparatus for controlling under dark ambient conditions the display intensity of an automobile display system comprises a plurality of display units (e.g., LED, FLT, Lamp) for providing displays effected by display elements of different types. Under dark ambient conditions, a pulse signal with a predetermined duty ratio is generated at a predetermined frequency and the display intensity of selected one of the display units is decreased in accordance with the duty ratio. Simultaneously, the duty ratio of the pulse signal is changed, and the display intensities of the other display units are decreased in accordance with the changed duty ratio.Type: GrantFiled: November 17, 1981Date of Patent: June 14, 1983Assignees: Nippondenso Co., Ltd., Toyota Jidosha Kogyo Kabushiki KaishaInventors: Tooru Mizuno, Yasuo Hagisato
