  • Patent number: 11394885
    Abstract: A predetermined image processing is carried out on the images that have been taken by the cameras 101 through 108 attached to a side of the cars that form a train before the images are displayed on the monitor 301 that is mounted in the train. That is to say, as a first image processing, among the images to be displayed, a left-right inversion process is carried out on the images where the positional relationship between the cars and the platform in the image is opposite between left and right to the positional relationship as viewed in the direction in which the train is to travel. In addition, as a second image processing, a cutout process is carried out on the images to be displayed so that the cutout regions differ in accordance with the opening and closing state of the doors.
