An efficient revising method was proposed to revise the display images of a Light Emission Diode(LED) captured by a color CCD camera. Firstly, the uniform standard white board was used to revise the vignetting phenomenon caused by a curved surface of color CCD camera in the manufacturing process. Then, on the basis of the distribution regularity of the lighting distribution curve of the LED, the deviation of LED itself caused by the camera position was revised also. The revising theory and revising process were described. Finally, relative data and conclusion were given. It shows that the uniform mean-square deviations of red, green and blue primaries have been decreased from 4.0% to 1.48%, 3.1% to 1.36% , and 3.5% to 1.39%, respectively, after revising. It is shown that this method is an efficient one. It not only eliminates the vignetting phenomenon caused by the curved surface of the camera itself, but also removes the deviation caused by the capturing angle of the CCD camera. The experimental results meet the requirements of image revising basically.
