In order to further develop a device (100) as well as a method for correcting at least one colour image, the method comprising the steps of - detecting the luminance (L), the saturation (S) and the hue (H) of the colour image, modulating the white -point (W), the saturation (s) and the hue (H) of the colour image, generating at least one colour gamut matrix for a colour conversion or colour mapping of the colour image, and hard clipping the converted or mapped colour image, in such way that the amount of calculation cycles is reduced by maintaining most of the clipping preserving effect of the adaptive colour gamut mapping (ACGM), it is proposed - to average the white-point (W), the saturation (S) and the hue (H) of the colour image, and to mix the averaged white-point (W), the averaged saturation (S) and the averaged hue (H) of the colour image in advance of the step of generating the colour gamut matrix. |
