Abstract
A road-surface state determination apparatus for a vehicle is provided. The road-surface state determination apparatus includes an acquiring unit and a control unit. The acquiring unit acquires, as a first detection signal, information on a changed pixel of which a luminance value changes based on an absolute displacement of a road-surface state or a relative displacement of the road-surface state relative to a moving vehicle. The control unit determines a type of the road-surface state using the first detection signal.
