Abstract
In order to improve the accuracy,stability and design flexibility of the color recognition system,based on field programmable gate array(FPGA)technology,a color recognition system applying to the static pictures was designed,in which the touch screen capabilities was set. By touching the corresponding RGB color value of the screen coordinates,the impact of the environmental change on the system is reduced and the color recognition is achieved by the threshold value determinate meth⁃od. The experimental results show that the system is stable and practical,can identify the colors of any bmp image with 800 *480 pixels,and has better robustness.关键词
