    摘要: A method comprises the steps of: monitoring a power consumption of a display; if the monitored power exceeds a maximum power threshold, then, ramping down an amount of power provided to a backlight of the display, and simultaneously increasing an amount of opening in light valves of a front modulator such that a brightness of the display is not diminished, wherein the ramping down and simultaneous increasing is performed on a regional basis so that, in at least one region of the display, the ramping down and simultaneous increasing is performed relatively more than in at least another region of the display. The disclosure further comprises a display and an electronically readable media.

    摘要: Methods and apparatus are provided for encoding and decoding image data using localized gamut definitions. The localized gamut definitions may be defined based on gamut characteristics of the image data. A gamut transform is applied to the image data wherein color coordinates specified by the image data are mapped to corresponding color coordinates in the localized gamut definition. Use of localized gamut definitions may facilitate image data compression or increased color depth specification of image data.
