Abstract
In a multi-window arrangement, the light output attributable to each window in a multiple window display is calculated, for example, in accordance with the video signal that provides the picture information for display in the window and in accordance with the window area. When the total light output contributed by all the windows exceeds a predetermined level, a loop controller automatically reduces, for example, the contrast and the brightness in selected windows, in accordance with a rule, in a loop control manner. The result is that the total light output drops below the predetermined level.
