Original Abstract
This paper deals with properties of specialized measuring instrument for assessment of quality of variable traffic sign panels. The device is based on analysis of luminance of single light points of the traffic sign matrix. Because the number of these points can grow into thousands, the visual analysis of extremely bright pixels is practically impossible. This device is able to evaluate number of statistic values and to provide very objective data for the panel producer about the whole quality of panel settings and therefore it enables eventual compensation of single sources excitation.
