  • Publication number: 20210109543
    Abstract: An obstacle identification apparatus acquires an image that is captured by a camera mounted to a vehicle. The obstacle identification apparatus calculates a first gradient that is a gradient in a first direction of a luminance value of pixels in the image and a second gradient that is a gradient of the luminance value in a second direction orthogonal to the first direction of the first gradient. Based on the first gradient and the second gradient, the obstacle identification apparatus estimates an own-vehicle shadow boundary. Based on the estimated own-vehicle shadow boundary, the obstacle identification apparatus estimates an own-vehicle shadow. Based on a luminance value of the estimated own-vehicle shadow, the obstacle identification apparatus estimates an object shadow that is a shadow of an object differing from the own-vehicle shadow.

  • Patent number: 10657654
    Abstract: An abnormality detection device includes: an estimator which estimates the amount of movement of a mobile body based on an image taken by a camera mounted on the mobile body; and a determiner which determines an abnormality in the camera by obtaining estimated information on the amount of movement of the mobile body as obtained in the estimator and actually observed information on the movement of the mobile body as detected by an external sensor, other than the camera, mounted on the mobile body.

  • Patent number: 10440317
    Abstract: A video processing device generates a display video signal to be supplied to a liquid crystal display unit that is driven by a frame inversion scheme. The video processing device includes a controller and a video signal processor. The controller controls a vertical synchronizing signal included in an interlace video signal input from outside the video processing device so that a display invalid section having a predetermined number of fields is set for the interlace video signal at a predetermined period. The video signal processor i) generates the display video signal based on the interlace video signal in which the display invalid section has been set by control of the vertical synchronizing signal and ii) outputs the display video signal to the liquid crystal display unit.

  • Patent number: 9524538
    Abstract: A first interpolation processor of an image processing apparatus performs a first interpolation process, using values of a plurality of input pixels of an input image aligned in an arranged direction that is one of a horizontal direction and a vertical direction. Thus, the first interpolation processor derives a value of each of a plurality of noted points on an inclined interpolation line inclined relative to the horizontal direction and extending through a location of a processed pixel of an output image. Moreover, second interpolation processor derives a value of the processed pixel by performing a second interpolation process, using the derived values of the plurality of noted points on the inclined interpolation line.
