PROBLEM TO BE SOLVED: To easily and exactly judge whether or not inspection light in a photographed inspection region is normally photographed. SOLUTION: A fluorescent light for illuminating band-like detection light on the surface of a vehicle body and a CCD camera photographing images of an illuminated location are scanned with robot hands. The photographed images are binarized to obtain binarized images 210. The widths of illumination range 212 are respectively measured on 3 measurement lines L1, L2 and L3 set in the scanning direction on the binarized image 210. By comparing the widths of the illumination range 212 with a first threshold and a second threshold, warning signal and error signal are generated. COPYRIGHT: (C)2005,JPO&NCIPI
