Abstract: The invention relates to a control module for a camera and an illumination apparatus, a camera, a production system and a method for acquiring images by means of such a camera. The exposure times and illumination times are controlled on the basis of a common control clock signal. Due to this, beats can be avoided. This even applies if short flashes are executed at irregular times.

Abstract: The invention relates to a method and a device for the scanning of a document by means of a line camera which has several scan lines and therefore generates several images independent of one another. Due to the spacing of the separate scan lines, these images are offset relative to one another. This offset also depends on the speed at which the line camera is moved relative to the document. According to the invention the separate images are brought into congruence by being shifted towards one another according to the whole-number content of Z, with at least one of the images being interpolated into the other image in accordance with the decimal place content of Z. The method according to the invention may be used to scan a document at a freely selectable scanning speed. The device according to the invention may be inserted as a module in an existing scanner.

Abstract: A method and a device for the optical scanning of a document by means of a line camera in which the document may be scanned at variable speed. Since on the one hand a line frequency by which the individual lines are scanned is based on the speed of movement, and on the other hand binning is carried out automatically on the basis of the speed of movement, wherein the line frequency is multiplied by a binning factor n, it is possible for a document to be scanned very easily and simply over a wide speed range. Color values are preferably corrected by means of an amplification factor, so that the brightness of the images produced by this means is constant over the whole speed range.
