VIDEO PROCESSING DEVICE AND METHOD OF COLOR GAMUT MAPPING

摘要

A video processing device is provided which comprises a color gamut mapping matrix unit (CGMM, ACGMM) for providing a color gamut mapping correction of an input signal and a mixing unit (MU) for applying a mix of color gamut mapped signals and the input signal based on a first correction factor (a) by mixing properties of the color gamut mapped input pixels with properties of the input pixels corrected by the first correction factor. The video processing device furthermore comprises a clipping unit (CLU) for clipping properties of pixels of an output of the mixing unit if these properties are not within a predefined range. Furthermore, a first control unit (CTRL1) is provided for determining the first correction factor (a) based on the amount of over and/or underflowing of pixels outputted from the mixing unit (MU). Hence, a correction of the input pixels is performed according to the overall underflowing of pixels.
