Abstract: A method for processing color image data that enables to optimally render a color image on a target device. The method incorporates a color gamut mapping step, where the amount of gamut mapping is adapted dynamically, in dependence of at least a color saturation value of the input pixel. Preferably, also a luminance value of the input pixel is used. The adaptive gamut mapping incorporates correction of saturation, and preferably also hue and white point, of the image data. The color gamut of the target device is used to the fullest possible extent, while clipping and loss of local details in highly saturated areas of the input image is largely prevented.

Abstract: A mobile device (200) is comprising: a display device (102) for displaying a number of display images of a sequence of display images, during a predetermined amount of time; and an energy resource (116) for providing the display device (102) with energy, is disclosed. The mobile device (200) further comprises energy management means for estimating an amount of available energy of the energy resource and control means (114) for controlling the number of display images on basis of the amount of available energy. Additionally the mobile device comprises an image acquisition unit, like for instance a camera.
