  • Patent number: 10763285
    Abstract: An image generation device includes a receiver and a controller. The receiver receives travel information about the travel state of a movable-body apparatus. The controller selects, based on the travel information, a first partial region from an entirety of a plurality of pixels of an image sensor or an entirety of image data captured by the image sensor, and generates image data in which a region other than the first partial region has a resolution lower than the resolution of the first partial region. The image sensor is to be mounted to the movable-body apparatus and is configured to capture an area in a traveling direction of the movable-body apparatus.
