Abstract
An apparatus and method for primary color correction and clipping is provided that is particularly suited for application in mobile displays. It is a combination of a brightness reduction, and a 'smart' clipping algorithm and is based on the perceptual attribute 'colorfulness', in which images that are brighter seem to posses more color. In the smart clipping algorithm, a brightness reduction is followed by a gamut (primary) correction and then a smart clip is performed by 'adding white' to the out-of-gamut pixels only. This reduces the saturation while it increases the brightness. That is, the saturation is decreased in favor of increased brightness, which gives similar colorfulness on a mobile display as on an EBU display. This smart clipping affects those colors that cannot be represented on the display.
