The uneven illumination of aerial images will cause color or luminance difference in an image frame. The difference will further affect the production quality of digital aerial images and the further applications of them. This paper analyses the causes of the uneven illumination of aerial images and characters of them

and deeply studies the application of the MASK dodging in the aerial images. Then based on the MASK dodging principle

this paper presents the processing flow and the corresponding processing method aiming to remove the uneven illumination of the digital aerial images. Finally the experiment is given

which shows that the method presented by this paper can be applied in many cases and avoid the disadvantages of methods based on the mathematical model. The experiment also shows that the method can achieve a satisfied effect and remove the uneven illumination for digital aerial images effectively.
