In order to get clearer and more qualitative image,an embedded high speed image enhancement processing system on high performance DSP TMS320C6455 and FPGA was designed,and a new fast color image enhancement algorithm is presented.First,the color image is transformed from RGB to HIS.Then multi-scale retinex algorithm is adopted in the brightness image.Finally the color image is transformed from RGB to HIS.Experimental results with real images show that the system can improve the contrast of the fog-degraded image,effectively enhance the color image and shorten the running time of the program,which can meet the project.
