Abstract

To improve the display effect of LED display,an adaptive gamma correction algorithm based on FPGA is proposed.Firstly,the system collects the surrounding information in real-time and performs gray processing through the camera.Secondly,the gray image is divided into two parts:the surrounding environment and the light board.Thirdly,the gamma correction parameters are determined by comparing the average brightness information of the two parts.Finally,real-time gamma correction is performed on the input video source.The experiment results show that the algorithm can be applied to LED display system with input 1080P@60 Hz,and the gamma correction effect is obviously compared in different environments,and the comfort of human eyes is effectively improved.
