  • Patent number: 10647255
    Abstract: An image processing device according to an aspect of the embodiment includes an image generating unit that generates an image at a virtual viewpoint based on a captured image of an image capturing unit, and an image processing unit that generates an image in which an image for synthesis is displayed on the image at the virtual viewpoint. The image processing unit performs a process for decreasing visibility of the image for synthesis when the image at the virtual viewpoint is an image at a viewpoint location of the virtual viewpoint while the viewpoint location is moving.

  • 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: 10132227
    Abstract: Upon a valve rotation angle of a flow rate control valve exceeding a radiator-flow-path closed position during changing of the valve rotation angle of the flow rate control valve in an opening direction of a radiator flow path from a closed state of the radiator flow path, a cooling water starts to circulate through the radiator flow path, and an outlet water temperature or an inlet water temperature of an engine starts to drop. The radiator-flow-path closed position is learned as a valve rotation angle of the flow rate control valve immediately before the outlet water temperature or the inlet water temperature starts to drop during changing of the valve rotation angle of the flow rate control valve in the opening direction of the radiator flow path from the closed state of the radiator flow path.

  • 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.
