PROBLEM TO BE SOLVED: To provide an image processing system or the like capable of recognizing lane marks in an image of a road surface with high accuracy even if the state of light irradiated on the road surface varies partially.;SOLUTION: Using the image processing system 100 mounted on a vehicle 10, the color components Rij, Gij, Bij of a first pixel Pij included in an area Aij set in an image of a road surface are corrected on the basis of the color components Rik, Gik, Bik of a second pixel Pik, in view of the fact that the color components of the second pixel included in the area along with the first pixel are also highly likely to be affected by shadows or light in the portion of the road surface. In this way, the influence of shadows or light on the road surface is reduced and the actual colors of the portion of the road surface corresponding to the first pixel are fully reflected on the color components Rij, Gij, Bij of the first pixel Pij and also on a characteristic quantity Qij. Based on the characteristic quantity Qij of each pixel Pij in the image of the road surface, a lane mark M and its edge E are recognized in the image of the road surface.;COPYRIGHT: (C)2007,JPO&INPIT
