  • Patent number: 10471884
    Abstract: In a headlight optical-axis control device 10, a controller 15 is configured to: calculate vehicle angles indicating tilt angles of a vehicle relative to a road surface, on the basis of ratios, each being a ratio of a difference between a reference acceleration in a longitudinal direction and a signal indicating an acceleration in the longitudinal direction detected during traveling of the vehicle, to a difference between a reference acceleration in a perpendicular direction and a signal indicating an acceleration in the perpendicular direction detected during traveling of the vehicle by an acceleration sensor 2; calculate a plot of the calculated vehicle angles thereby to derive a vehicle angle corresponding to a case where a change of the acceleration in the longitudinal direction is zero; and generate a signal for controlling the optical axes of headlights 5L and 5R on the basis of the derived vehicle angle.

The image sensing device has an image sensing surface divided into a first image sensing area for recording the first subject image and a second image sensing area for recording the second subject image. The image sensing device has, on the image sensing surface, a wavelength filter that transmits, in the first image sensing area, light in the first wavelength range alone and, in the second image sensing area, light in the second wavelength range alone.

  • Patent number: 9020281
    Abstract: Two imaging optical systems are provided. The two imaging optical systems are configured to have a difference in a ghost appearance condition under the same imaging condition by differentiating at least one of the angle, the resolution, and the variation adjustment in production. In Step S1, images captured by the two imaging optical systems are stored. In Step S2, corresponding positions of each respective portion of a subject between the two imaging optical systems are obtained. In Step S3, images at the corresponding positions are compared with each other for determining a bright portion having a deviation in a luminance value, as a ghost portion. In this configuration, it is possible to accurately detect a ghost generation position on a real-time basis.

  • Patent number: 8538634
    Abstract: Body velocity estimating device 10A is constituted by acceleration measurement unit 11, acceleration separation unit 12, filter processing operation unit 13, acceleration addition unit 14, integration processing operation unit 15, and estimated body velocity output unit 16. The unit 12 compares an acceleration measured by the unit 11 with set acceleration upper and lower limit reference values to separate the measured acceleration into reference value range-in and range-out accelerations. The unit 13 performs filtering on the separated reference value range-out acceleration to calculate filtered accelerations of the reference value range-out acceleration. The unit 14 adds the filtered accelerations to the previously separated range-in acceleration. The unit 15 multiplies the added acceleration by an operation period, and adds the resultant to the estimated body velocity calculated in the preceding one operation period to update the value of the estimated body velocity.
