Abstract

Display systems, control systems for a display and a method for operating a display are provided in which people are detected a presentation space within which content presented by the display can be observed. Viewing areas are defined for each person with each viewing area comprising a less than all of the presentation space and including an area corresponding to each person. One channel of image content is obtained for presentation to each person and a combination image is presented on the display. The combination image is modulated so that each area of the combination image presented by the display is viewable only in selected areas of the presentation space. The combination image has image content from each channel of image content arranged in areas of said combination image so that, when modulated, the image content from each channel of image content is viewable only in a viewing area defined for the person for whom the content is obtained.
