Three feature values are obtained, that is, the amplitude feature value of the road surface image, a difference between the FFT amplitude feature values of the actual road surface image and the standard road surface state and a difference between the maximum and the minimum values from the R, G and B values of the road surface image. Then the normal distribution curve of each standard road surface state is calculated and a standard table is generated.  The actual road surface image photographed by the camera is FFT-processed and the amplitude characteristic is made into an image as the density and displayed on the monitor. Then the actual feature values are obtained, i.e., the amplitude feature value of the actual road surface image, the difference between the FFT amplitude feature values of the actual road surface image and the standard road surface state and the difference between the maximum and minimum values from the R, G and B values of the road image. The actual feature values are fetched into the standard table to calculate each probability and to obtain an integrated probability. Then each road surface state is detected based on the integrated probability.
