Digital billboards dynamic luminance measurements

Abstract

In the opinion of the drivers, digital billboards and telebims are a potential threat to road traffic. Multimedia content with dynamically changing luminance level over time is often presented on emission media. The problem was highlighted when trying to regulate the requirements for dynamic media in law. The Ministry of Infrastructure and Development is in the process of drafting regulations aimed at limiting the emission parameters of light commercials used in the road environment. The limitation is to apply to the maximum luminance parameters emitted during the daylight and night, with the limitation to the built-up area and outside the built-up area. It is also proposed to limit the switching time of the image sequence and its luminance level. In the article have been describe the test procedure with presented sample measurement results. The object of research was medium-size advertising, where the illuminating surface was made with the use of semiconductor LED light sources. Obtained results undoubtedly indicate that there is a problem with measuring the parameters of advertising luminance with dynamically changing content.
