A method for the independent control of the contrast and / or the brightness of a plurality of images, and circuit arrangement for carrying out this method

摘要

Images defined by pixel groups are reproduced on an image reproduction unit according to a general scaling function. When the user changes an image's window value the image is regenerated using a different scaling function defined by the current image window and level values. When at least one other image window value is changed, the image pixel group is replaced by corresp. values derived from the other scaling function and displays the image according to a scaling function defining a 1:1 identity function. ADVANTAGE - Some limitations and disadvantages of conventional systems, e.g. costly overheads, are eliminated.
