TECHNIQUES TO CONTROL FRAME DISPLAY RATE

摘要

Techniques to determine when to decrease a frame display rate based in part on the amount or degree of change between sequential frames. The amount or degree of change can be measured based on all or part of similarly located portions of sequential frames. In some cases, power use can be reduced without compromising visual quality by reducing frame display rate when an amount or degree of change between frames is small.

主权项

1. An apparatus comprising:
a graphics processor; a change detection device to determine a measure of change between portions of at least two frames and to indicate the measure of change; a processor configured to access the measure of change and to selectively adjust a target frame display rate at which the graphics processor is to provide one or more frames for display, where to selectively adjust, the processor is to:
set the target frame display rate to a first frame rate in response to the measure of change being the same or higher than a threshold andset the target frame display rate to a second target frame rate in response to the measure of change being less than the threshold.
