Patent number: 10406993Abstract: A method of manufacturing a vehicle in which a vehicle-mounted camera is attached to a glass surface on a vehicle interior side of a window glass of a vehicle body, and includes a seat fixed to the glass surface and including a seat surface extending along a predetermined direction and preferably formed by machining, includes determining the predetermined direction on the basis of an inclination angle of the glass surface to set an optical axis direction of the vehicle-mounted camera in any direction. The method of manufacturing provides a vehicle-mounted camera that is low in costs and includes an optical axis with an angle which is easy to adjust.Type: GrantFiled: August 26, 2016Date of Patent: September 10, 2019Assignee: NIDEC CORPORATIONInventor: Yushi Takehara

Patent number: 10318825Abstract: In a vehicle-mounted image recognition apparatus, a resolution of an image projected on an imaging plane of an image sensor is different at a position away from a center between a circumferential direction and a radial direction. To make a circumferential resolution higher than a radial resolution, at least a lower half of the imaging plane is located closer to a circumferential focus than a middle of a radial focus and the circumferential focus at a position off the optical axis center of the image projected on the image sensor through the image-forming optical system. This is achieved by adjusting the position of the imaging plane when manufacturing or by selecting a lens with high circumferential resolution. This apparatus improves recognition accuracy in recognizing traffic lanes without using an expensive lens exhibiting high resolution both in the circumferential direction and in the radial direction.Type: GrantFiled: October 25, 2017Date of Patent: June 11, 2019Assignees: NIDEC COPAL CORPORATION, NIDEC ELESYS CORPORATIONInventors: Yuta Nakamura, Yohei Nagai, Yushi Takehara, Naoya Takeda

Patent number: 9407802Abstract: An imaging apparatus includes an image-forming optical system assembly, an image sensor, a sensor retaining portion that retains the image sensor, a coupling portion that is fixed to the image-forming optical system assembly, and a movement suppressing member that is immovable with respect to the coupling portion. The image-forming optical system assembly includes an optical system-side adhesive surface, the coupling portion includes an opposite surface, and the sensor retaining portion includes a sensor-side adhesive surface. A first adhesive is filled in at least a portion of a gap between the optical system-side adhesive surface and the sensor-side adhesive surface, and comes into contact with both of the optical system-side adhesive surface and the sensor-side adhesive surface. The movement suppressing member contacts the opposite surface, and contacts the sensor retaining portion on a surface facing the rear side out of surfaces of the sensor retaining portion.Type: GrantFiled: June 25, 2015Date of Patent: August 2, 2016Assignees: NIDEC COPAL CORPORATION, NIDEC ELESYS CORPORATIONInventors: Yuta Nakamura, Yohei Nagai, Yushi Takehara, Naoya Takeda
