  • Publication number: 20140132739
    Abstract: Although a conventional method can eliminate a mounting position deviation when left and right camera units only are taken into consideration, a problem is posed that deviation again occurs due to poor machining precision and assembly precision at the mounting surface between a camera unit and a member when a camera unit is mounted to a stay. According to this invention, mounting surfaces for mounting left and right imaging elements to a stay are provided to directly position left and right imaging elements to the stay, whereby built-up tolerance between components is reduced and the positional mounting precision between imaging elements is improved.

  • Publication number: 20130251883
    Abstract: The present invention discloses a method of manufacturing porous granules, a porous granule obtained by the method, a lipid-containing granule and a method of manufacturing thereof, and a food containing the lipid-containing granules and a method of manufacturing thereof. The porous granule of the present invention is bigger than the granule manufactured by the spray drying method, has high solubility, is easily obtained (porous structure can be easily formed), and has enough hardness. In addition, drying time and drying cost can be reduced because an amount of water to be dried can be reduced. The porous granule can be obtained by mixing a powder whose solubility is at most 100 g per 100 mL of water at 20° C., with water and drying a mixture under reduced pressure to obtain the porous granules having loose bulk density of at least 0.30 g/mL, having porous structure, and capable of absorbing lipids.

  • Patent number: 8223203
    Abstract: Disclosed herein is a vehicle-mounted type of camera capable of being reduced in the space required for installation on the windshield of a vehicle. An imaging unit 15 is provided on a substrate 19 and has an optical axis in a direction perpendicular to the substrate surface. The substrate 19 is set up in parallel with respect to the windshield of the vehicle. A lens 14 is disposed on the optical axis. A mirror 16 is also provided on the optical axis of the imaging unit 15, and is adapted to change a direction of the optical axis to a frontward direction of the vehicle, thus guiding frontward visual field information of the vehicle to the imaging unit 15. The mirror 16 is retained in an attachment 11. The attachment 11 can be engaged with and disengaged from an enclosure 12 that holds the lens 14.

  • Publication number: 20080001727
    Abstract: According to a conventional technique, first, the positional relation between a lens and an imaging element is kept at each of left and right camera units, adjustment is made so as to eliminate the rotation-direction deviation of an imaging element from one surface of a member to which a lens and an imaging element are to be attached before fixing, and then that camera unit is attached to a reference member to thereby constitute a stereo camera. However, although this method can eliminate a mounting position deviation when left and right camera units only are taken into consideration, a problem is posed that deviation again occurs due to poor machining precision and assembly precision at the mounting surface between a camera unit and a member when a camera unit is mounted to a stay.

  • Patent number: 7247838
    Abstract: An image processing system includes a lamp which emits light to a glass, an imaging device which captures light which is emitted from the lamp and reflected by the glass, and an optical filter, located between the glass and the imaging device, which transmits rays with a specific wavelength of the reflected light. A lens is provided in front of the imaging device, and a focus of the lens is adjusted to a point beyond the glass, and an image processor is provided which processes an image captured by the imaging device and detects moisture on the glass.

  • Patent number: 7208723
    Abstract: An image processing system that detects foreign matter on a glass window of a vehicle and objects in front of the vehicle. The system includes an image processor, a first lamp, and a second lamp. On/off control of the first and second lamps is controlled by the image processor. Light from the first lamp is reflected from the outer sauce of the glass when raindrops are present on the outside of the glass. Light from the second lamp is reflected from the inner surface of the glass when moisture is present on the inside of the glass. Any reflected light goes through a lens and an optical filter with prescribed optical characteristics to an image device. The lens is focused to a point beyond the window so that the image processor an also detect objects in front of the vehicle.

  • Publication number: 20050035926
    Abstract: An image processing system which detects foreign matter on window of a vehicle with high reliability. The system includes an image processor, a first lamp, and a second lamp and when to turn on the first and second lamps is controlled by the image processor. Light from the first lamp passes through the glass. If there are raindrops on the outer surface of the glass, light is reflected by raindrops and light from the second lamp is reflected by a surface of the glass and such reflected light goes through a lens and an optical filter with prescribed optical characteristics to an imaging device.
