20160125580 | MAPPING IMAGE/VIDEO CONTENT TO TARGET DISPLAY DEVICES WITH VARIABLE BRIGHTNESS LEVELS AND/OR VIEWING CONDITIONS - An image processing system performs intensity mapping in a manner that avoids color shifts and conserves processing resources while adapting image data for a target display device.
