In order to remove the uneven illuminations of a digital image from the LED light and CCD-based machine vision system, a new method based on a light illumination model is presented for correcting the uneven illuminations in this paper. The experiment results show that the method has excellent correction effects in the uneven illumination of LED light, CCD surface and stained lens. As a result, this method can be widely used in such LED light and CCD-based machine vision systems to dramatically increase their inspecting precisions and detecting speed.
