Abstract
The invention relates to a display device for rendering gray tone images on a monitor controlled by s electron rays. The display device includes a correction unit for generating s output image signals A composed of gray tone values forming part of a set K of correction gray tones from an image signal. The image signal is composed of gray tone values forming part of a set M of original gray tones, and the s output image signals A , after a D/A conversion, are fed each to one electron ray for a brightness-corrected rendering of a gray tone in one pixel of the monitor for the purpose of adapting the brightness distribution of the monitor to the optimum perceptional brightness distribution.
