Abstract:
1. A method for displaying an image, said method comprising: a) analyzing said image, with a computing device, to determine an adjusted display source light illumination level; b) using said adjusted display source light illumination level to determine a tone scale adjustment model that is dependent on said source light illumination level, wherein application of said tone scale adjustment model to said image adjusts pixel code values in said image thereby creating a tone scale adjusted image such that display of said tone scale adjusted image using said adjusted display source light illumination level produces similar output as said pixel code values would produce when displaying said image using a full source light illumination level; c) applying said tone scale adjustment model to said image to produce a tone scale adjusted image; and d) displaying said adjusted image on a display using said adjusted display source light illumination level, wherein said adjusted display source light illumination level is used to control a display source light for all color channels of a display during said displaying.
