  • Publication number: 20220292691
    Abstract: A generation unit generates a background separation image in which regions of a captured image are classified as a foreground region, a background region, and an unknown region, based on distance distribution information obtained from a plurality of parallax images. An output unit outputs the captured image and the background separation image. A region in which a distance in the distance distribution information is within a first range is classified as the foreground region. A region in which a distance in the distance distribution information is outside a second range broader than the first range is classified as the background region. A region in which a distance in the distance distribution information is outside the first range and inside the second range is classified as the unknown region.
