In order to enhance the display result of the LED display image, an improved algorithm of LED display image based on composed correction is proposed. Firstly, the correction principle and the development status of the current correction technologies of the LED display image is introduced, and the two main correction technologies are analyzed. Secondly, the theory of composed correction is propo...

Article history: Received 17 December 2014 Received in revised form 1 December 2015 Accepted 3 December 2015 Available online 19 December 2015 The data for the lightflux degradation and chromaticity shift of LED lamps exhibits a considerable amount of scatter due to intrinsic and extrinsic factors. In this study, some degradation models, such as the gamma process model, were reviewed in terms o...

In this paper, we would like to introduce a second generation of headlight glare simulator to be used with a driving simulator that significantly improves spatial and brightness accuracy of previously developed prototype headlight glare simulator (Fullerton & Peli, 2009). The system combined a programmable off–the-shelf LED display board and a beamsplitter so that the LED lights, representing h...
