The techniques of the disclosure are directed to reducing power consumption in a device through adaptive backlight level (ABL) scaling. The techniques may utilize a temporal approach in implementing the ABL scaling to adjust the backlight level of a display for a current video frame in a sequence of video frames presented on the display. The techniques may include receiving an initial backlight level adjustment for the current video frame and determining whether to adjust the backlight level adjustment for the current video frame based on a historical trend. The techniques may also determine the historical trend of backlight level adjustments between the current video frame and one or more preceding video frames in the sequence.
A method of controlling an illumination level of a display, the method comprising:
A device for displaying a current video frame in a sequence of video frames presented by the device, the device comprising:
A device for displaying a current video frame in a sequence of video frames presented by the device, the device comprising:
A computer-readable medium comprising instructions that, when executed, cause a processor in a device for displaying a current video frame in a sequence of video frames presented by the display to:
