  • Patent number: 9706175
    Abstract: In an image processing device configured to be installed in a vehicle, an image acquirer acquires camera images captured by cameras provided on the vehicle. A synthetic image generator generates synthetic images, which include downward views of the vehicle and a periphery thereof viewed from viewpoints different from one another, based on the camera images. A display image provider outputs, to the display device installed in the vehicle, information corresponding to a display image in which the synthetic images are continuously reproduced.

  • Publication number: 20120249796
    Abstract: In an image processing device configured to be installed in a vehicle, an image acquirer acquires camera images captured by cameras provided on door mirrors of the vehicle. An image selector selects a first part of the camera images in a case where the door mirrors are placed in a closed position, and to select a second part of the camera images in a case where the door mirrors are placed in an opened position. A display image provider outputs, to a display device installed in the vehicle, information corresponding to either one of the first part and the second part of the camera images selected by the image selector.
