Vignetting for an image refers to the phenomenon of brightness attenuation away from the image center, and it is a more concerned artifact for high resolution camera. This contributes to vignetting results from foreshortening of the lens when viewed from increasing angles from the optical axis. High resolution cameras suffer for this kind of artifact more. It is a concern to reduce the vignetting artifact by using less memory consumption. In this book, we consider the vignetting resulting from the mentioned factor almost any kind of sources and propose a method for removing the vignetting artifact after taking the image and linearization of that image. We synthesized some parameters on the basis of vignetting artifact for a particular digital camera. This approach takes very limited bits of memory that is necessary for mobile device. By applying our approach, it shows how this approach is efficient to reduce the vignetting artifact with limited memory consumption. The basic formation of a digital camera image from natural scene is also described clearly in this book.
