Abstract

The invention relates to a method for automatic imaging correction of a projector (100) for digitized images, wherein the projector (100) comprises a camera (102) for capturing the projected image and wherein the captured projected image is compared with at least one image projected under normal conditions and on the basis of the comparison the projection optics (101) of the projector (100) are modified and/or the projected image is distorted in the projector (100) until the captured projected image is identical with the at least one image captured under normal conditions in the range of a preselected tolerance interval. According to the invention, the method and the corresponding projector permit an automatic imaging correction.
