This article describes the study of the detection and correction of diverse errors that can occur while taking digital photographs of flat objects such as pages from a book or magazine. This paper deals with uneven lighting conditions and the consequences thereof on the brightness of the photographed subject, geometric image distortions due to the technical characteristics and the chosen settings on the camera, and possible distortions because of the surface on which the photographed material is positioned. The processing of the data is done with Matlab. The user is supposed to make correct use of adequate reference material as a means for the identification of the imperfections in the registration system to make the necessary corrections. The final purpose of all these procedures is to reproduce the photographed material as truthfully as possible.
