Patent number: 8233046Abstract: A facial image photographic device for vehicle mounting includes a facial image photographic camera which photographs the face of a driver of a vehicle while the vehicle is running, and a changeover device. The changeover device changes over a utilization environment of the facial image photographic camera between a position in which, when performing photography, the facial image photographic camera can be exposed to direct insolation by sunlight, and a position in which, when not performing photography, at least a part of the facial image photographic camera is not to be exposed to direct insolation by sunlight than when performing photography.Type: GrantFiled: September 4, 2006Date of Patent: July 31, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kenichi Ohue, Masayuki Usami, Shigeyasu Uozumi

Patent number: 8184008Abstract: An on-board warning apparatus of the invention includes an inattentive time measuring device that measures a duration of an inattentive state of a driver; a dozing time measuring device that measures a duration of a dozing state of the driver; a first warning output device that warns the driver when the measured inattentive time exceeds a first predetermined period of time Ta; and a second warning output device that warns the driver when the measured dozing time exceeds a second predetermined period of time Tb. The first predetermined time Ta is shorter than the second predetermined period of time Tb.Type: GrantFiled: October 10, 2007Date of Patent: May 22, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventors: Shigeyasu Uozumi, Kenichi Ohue

Patent number: 7916904Abstract: An image capturing section captures a face of an observed person. A position detecting section detects, from a face image expressing the face captured by the image capturing section, one of a position expressing a characteristic of a nose and a position expressing a characteristic of a region between eyebrows. A computing section computes a past relative position of a predetermined region of the face that is based on the position detected in the past by the position detecting section. A region position detecting section detects a position of the predetermined region on the basis of the past relative position computed by the computing section and the current position detected by the position detecting section.Type: GrantFiled: March 18, 2008Date of Patent: March 29, 2011Assignees: Aisin Seiki Kabushiki Kaisha, Toyota Jidosha Kabushiki KaishaInventors: Tomoharu Suzuki, Jun Adachi, Shinichi Kojima, Kenichi Ohue, Yuji Ninagawa, Shigeyasu Uozumi

Patent number: 7907752Abstract: It is possible to accurately detect a face center position based on an image of a person when the person is wearing glasses even when the person is facing sideways. Face images obtained as a result of photographing a face of a driver using a camera (10) are stored in an image memory (22). The CPU 24 determines positions of the sides and top and bottom positions of the face based on the face images stored in the image memory (22). Further, the CPU 24 determines whether or not the driver is wearing glasses or is facing sideways. When the wearing glasses and facing sideways is determined, a face center position is detected using face images for a lower region of the face. As a result, it is possible to detect a face center position in a reliable manner even when a driver wearing glasses is facing sideways.Type: GrantFiled: October 19, 2006Date of Patent: March 15, 2011Assignees: Aisin Seiki Kabushiki Kaisha, Toyota Jidosha Kabushiki KaishaInventors: Junya Kasugai, Takeshi Naito, Hiroshi Ishiguro, Shigeyasu Uozumi, Kenichi Ohue
