The invention relates to a display device for rendering gray tone images on a monitor (31) controlled by s electron rays, wherein a correction unit (33) is provided for generating s output image signals As, which comprise gray tone values forming part of a set K of correction gray tones, from an image signal (34) which comprises gray tone values forming part of a set M of original gray tones (23), and the s output image signals As, 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 (31) for the purpose of adapting the brightness distribution of the monitor to the optimum perceptional brightness distribution.
A display device for displaying gray tone images with a monitor (31) driven by s electron rays, characterized in that a correction unit (33) is provided for generating s output image signals As, which comprise gray tone values forming part of a set K of correction gray tones, from an image signal (34) which contains gray tone values forming part of a set M of original gray tones (23), and in that said s output image signals As, after a D/A conversion, are designed to be supplied each to an electron ray of the monitor for a brightness-corrected display of a gray tone in a point of the monitor (31).
A display device for rendering gray tone images with a triple-gun monitor driven by three electron rays, characterized in that a correction unit (33) for generating three corrected output image signals As from a set M of original gray tones (23) of an image signal (34) is provided, and in that said three output image signals As, after a digital/analog conversion, are designed to be fed each to one electron ray of the triple-gun monitor for being jointly pictured on a pixel for a brightness-corrected display of the gray tone on the triple-gun monitor.
