Adaptive frame rate control for power savings

摘要

Embodiments disclosed herein pertain to power conservation for electronic devices. According to one embodiment, power conservation can be achieved through adaptive frame rate control for a display associated with an electronic device. The frame rate is able to be controlled so as to adapt to a frame rate that is adequate for the display task. Since the display often times displays content that is not very dynamic, the frame rate in such situations can be controlled to use a reduced frame rate, which thereby reduces power consumption. However, when the display displays content that is substantially dynamic, the frame rate in such situations can be controlled to use an enhanced (or not reduced) frame rate, which ensures reasonable display quality.

主权项

1. A method of controlling frame rate for dynamic data displayed on a display of a computing device, the method comprising:
evaluating data to be displayed, the data including a plurality of sequential blocks of data, and the evaluating including determining a degree of change in a current block of data from the plurality of sequential blocks based on comparing the current block of data to a prior block of data from the plurality of sequential blocks of data; adaptively determining a frame rate to be used for displaying the current block of data when the degree of change exceeds a threshold value; setting the frame rate to the determined frame rate; displaying, in response to the setting of the frame rate, the current block of data on a display in accordance with the determined frame rate; and repeating the evaluating, the determining, the setting and the displaying for subsequent blocks of the plurality of sequential blocks of data.
