Abstract
A histogram is calculated based on a road surface image of a portion around a vehicle, and the histogram is separated into a histogram that represents an in-sunlight road surface and includes a first peak value and a histogram that represents a shadow road surface and includes a second peak value to output the histograms, thereby further enhancing the accuracy of road surface detection around the vehicle as compared with conventional art.
