REFLECTION CHARACTERISTIC EVALUATION DEVICE, REFLECTION CHARACTERISTIC EVALUATION METHOD AND REFLECTION CHARACTERISTIC EVALUATION PROGRAM

摘要

<P>PROBLEM TO BE SOLVED: To provide a reflection characteristic evaluation device for stably and precisely judging the reflection characteristics of a surface without requiring cost in a case that the image photographed by a camera is inputted and the reflection characteristics of the surface part in the inputted image are outputted. Ž<P>SOLUTION: The reflection characteristic evaluation device constituted so as to determine a threshold value for judging whether the surface part is mirror reflection or diffused reflection by the dispersion of the brightness variation of a circumferential part in the case that the image photographed by a camera is inputted and the reflection characteristics of the surface part in the inputted image are outputted and the surface part is set as the mirror reflection if the brightness variation of the surface part is more than the determined threshold value and outputted as the diffused reflection if the brightness variation of the surface part is below the determined threshold value.
