Abstract

The invention provides an apparatus for dynamically adjusting the saturation of an image signal consisting of a plurality of pixels. The apparatus includes a first transformation module, an operation module, a gain module, an adjustment module and a second transformation module. The first transformation module transforms the pixels of the image signal into a plurality of intermediate signals, where each of the intermediate signals has a respective saturation value. The intermediate signals are adjusted in accordance with a gain signal determined by a histogram relative to the saturation distribution of the intermediate signals. The adjusted intermediate signals are transformed back into the pixels of the image signal, thereby the saturation of the image signal is adjusted.
