Abstract

The invention concerns the elimination of the image steadiness error in the projection of films, which consist of individual images. For this purpose, the image steadiness error is detected by a sensor and is compensated for by a device for step size compensation. An apparatus for the measurement of the image position in the projection films which consist of individual images has a sensor for the measurement of the image steadiness error by making use of the perforation. In a device for the correction of an image steadiness error of films which consist of individual images, an optical compensator is arranged before the films as an optical storage medium and/or before the optical photography medium.
