One is the natural genetic factor, and the other is by the chemicals or the damage of nerve or brain. In the previous research and literature surveys, it shows that there are about 8% of male and 0.5% of female with the red-green color blindness in the world population. Among them, there are 6% the world population with trichromatic vision (weak color vision), 2% the world population with dichromatic vision (partial color blindness), and few world population with monochrome vision (total color blindness). If the color blindness is caused by the environment, it can be cured by medicine. But the natural color blindness cannot be cured by the existing operations. Although there are coated glasses which can be used to “correct”the color vision, no good results are shown presently. There still lack of efficient and suitable pproaches to solve this problem currently. The color blindness cannot choose the job related to art, medicine, chemical, electrical and telecommunications, etc. All these jobs depend on the ability to distinguish different colors. They also cannot take the driving license. To help the color deficiencies, we propose to use the computer algorithms to adjust the color and let the color deficiencies be able to distinguish the difference between the colors. We the algorithms used for digital images, and tested by the color deficiencies. Based on some preliminary research, we would also like to extend and use it for portable devices.
