Abstract

An apparatus for the reproduction of video signals on a monitor has a circuit connected with the monitor for the conversion of grayscale values of a video signal. The apparatus has a computing unit connected to the conversion circuit which, on the basis of a statistical evaluation of the grayscale distribution, recalculates the standard used for the conversion of the grayscale values so that in the display of an image on the monitor the dynamic range within a region of interest is completely utilized. The conversion circuit is supplied with the calculated, corrected values for the conversion from the calculating unit.
