Abstract
A display system uses a post-scaling module for producing a single scaling factor. A post-scaling unit for scaling image data values is constructed as a function of scaling requirements, such as backlight illumination, saturation of the image data values, and out-of-gamut correction. This single scaling factor may be a function of the scaling requirements. Some of these scaling requirements could be selected from a group scaling considerations, such as saturation based scaling, out-of-gamut scaling, and non-linear scaling. A non-linear scale module could be used to enhance dark color values and may depend on the luminance value of image data values. Once these scaling requirements are determined, there are ways of combining them to create the single scaling factor. These ways may include multiplying the scaling requirements, taking the minimum of them, or taking a combination of them.
