According to the disadvantage of color distortion of color histogram equalization algorithm
a new image enhancement algorithm based on dark channel prior is presented. First
the dark channel image is done. Then the transmission map and the atmospheric optical components map are estimated. Finally the bright values of the pixels of the image are calculated according to the atmospheric model. An embedded high speed image enhancement processing system on high performance DSP TMS320DM6437 and FPGA was designed. Experimental results with real images shown that the system can improve the contrast and color of the image
