Abstract
An image is displayed on an electronic display device at a reduced power level. Power used by the display device is maintained below a predetermined maximum power level by uniformly scaling the initial optical intensity of an image to a lower optical intensity whenever displaying the image at the initial optical intensity would result in power consumption of the display device exceeding the predetermined maximum power level.
Claims38
A method of displaying an image on an electronic display system, comprising:
- receiving frames of image data to be displayed;
- determining an average power level for displaying one or more frames of image data;
- and
- adjusting a parameter of the electronic display system in accordance with the average power level.
A method of displaying an image on a laser phosphor display device having a plurality of laser sources, comprising:
- receiving frames of image data to be displayed;
- determining an average power level for displaying one or more frames of image data;
- and
- modulating the laser sources in accordance with the average power level.
A method of displaying images on a display device, comprising:
- receiving an input representing one or more images to be displayed;
- determining a display value based on the input;
- comparing the display value against a threshold value;
- and
- adjusting a parameter of the display device based on said comparing.
An electronic display system having a processing unit and a memory device having instructions stored therein, wherein the processing unit executes the instructions to carry out the steps of:
- receiving frames of image data to be displayed;
- determining an average power level for displaying one or more frames of image data;
- and
- adjusting a parameter of the electronic display system in accordance with the average power level.
A computer-readable storage medium including instructions that, when executed by a processing unit, cause the processing unit to display images on a display device, by performing the steps of:
- receiving an input representing one or more images to be displayed on the display device;
- determining a display value based on the input;
- comparing the display value against a threshold value;
- and
- adjusting a parameter of the display device based on said comparing.
