Abstract: | To solve the problems of low speed of screenshot of computer screen images and large amount of image data in the large-scale LED lighting real-time control system, a new method to improve the efficiency of the screen image screenshot is designed based on screen Device Context (DC) method combined with map view of file technology. At the same time, Improved octree color quantization technology is utilized to reduce the amount of video image data and improve real time performance of the monitoring system, on the condition of good video image effects. The experimental results show that applying the Optimized method of improving the LED lighting effects could get a faster screenshot of screen image, and better effect of visual. The method is applied in the LED lighting real-time information system. |
