  • Patent number: 10882450
    Abstract: A vehicle periphery monitoring apparatus includes a camera, an electronic control unit and a display unit configured to display the display image. The ECU is configured to generate a display image of an external environment based on image information from the camera such that the display image includes a first display image from a first predetermined viewpoint from which one of right and left side surfaces of a host vehicle and a rear portion or a front portion of the host vehicle are obliquely seen from above. The ECU is configured to generate and output the display image including the first display image in at least any one of a predetermined first traveling status of the host vehicle, a predetermined periphery status of the area on either side of the host vehicle, and a state in which a turn signal lever is manipulated.

  • Patent number: 10750093
    Abstract: An image processing device according to an embodiment includes an image acquisition unit, an information acquisition unit, a generation unit, and a composition unit. The image acquisition unit acquires a captured image where an image of an environment of a vehicle is captured by an image-capturing device. The information acquisition unit acquires information regarding a detected position of an obstacle that exists in an environment of the vehicle. The generation unit generates a virtual viewpoint image where an environment of the vehicle is viewed from a virtual viewpoint, based on the captured image that is acquired by the image acquisition unit. The composition unit composites a notification image that provides notification of existence of the obstacle at the detected position with the virtual viewpoint image and composites a vehicle image with the virtual viewpoint image.

  • Patent number: 10579884
    Abstract: An image processing device according to an aspect of the embodiment includes a display controller and a determining unit. The display controller generates a synthesized image when viewing a perimeter of a vehicle from a virtual viewpoint based on an image from an image capturing device and causes a display unit to display the synthesized image. The determining unit determines, in a case where a screen other than a virtual viewpoint screen including the synthesized image is displayed on the display unit, whether a switching condition to a notification screen for notifying an occupant of presence of an obstacle is satisfied when the obstacle is detected by a detector. The display controller causes the display unit to display the notification screen obtained by superimposing a predetermined notification image on the virtual viewpoint screen, when the determining unit determines that the switching condition is satisfied.
