  • Publication number: 20230017893
    Abstract: An imaging system includes a light emitter that emits light toward the surroundings of a vehicle, an imager that captures an image of a range including a region that is illuminated with light emitted by the light emitter, and a difference image generator that generates (n?1) difference images from n captured images captured by the imager (n is an integer no smaller than 3). The difference image generator generates a difference image based on an image included in the n captured images and captured while the light emitter is on and an image included in the n captured images and captured while the light emitter is dimmed.
