1. A method for a disturbance-free image acquisition, which comprises the steps of: continuously increasing a coupling between a given image to be acquired and an electronic sensor; using the electronic sensor for recording a sequence of images during the coupling; choosing one of the images from the sequence of images as a starting image according to predetermined criteria; choosing from the sequence of images, at least one further image to be one of a correction image and used for determining the correction image; and correcting the starting image by subtraction of the correction image.
