Abstract

In accordance with some embodiments, the render rate is varied across and/or up and down the display screen. This may be done based on where the user is looking in order to reduce power consumption and/or increase performance. Specifically the screen display is separated into regions, such as quadrants. Each of these regions is rendered at a rate determined by at least one of what the user is currently looking at, what the user has looked at in the past and/or what it is predicted that the user will look at next. Areas of less focus may be rendered at a lower rate, reducing power consumption in some embodiments.

First claim

What is claimed:

1 . A method comprising:
identifying two different screen regions of one screen display; and rendering the two regions of the one screen display at different rendering rates.

2 . The method of claim 1 including identifying a screen region the user is currently looking at.

3 . The method of claim 1 including predicting a screen region that a user will look at next.

4 . The method of claim 3 including predicting based on a historical viewing pattern.

5 . The method of claim 3 including predicting based on what will be displayed in the future.

6 . The method of claim 3 including detecting a user's viewing pattern and using that detected pattern to predict a region that will be viewed in the future.

7 . The method of claim 1 including defining more than two screen regions.

8 . The method of claim 1 including implementing more than two render rates on the same display.

9 . The method of claim 2 including rendering a region the user is not currently looking at with temporal anti-aliasing and rendering another region with multi-sampled anti-aliasing.

10 . The method of claim 3 including tracking a moving screen object to predict which region will be viewed by the user in the future.

11 . The method of claim 1 further comprising:
selecting assigning cores of different precision to each of at least two distinct screen regions; and
rendering each of said region with a core of different precision.

12 . The method of claim 11 wherein said cores are part of a common processing unit.

13 . The method of claim 12 wherein said cores are part of a graphics processing unit.

14 . The method of claim 11 wherein a core of higher precision is assigned to render a screen region of higher significance.

15 . The method of claim 14 wherein said region of higher significance is identified by eye gaze detection.

16 . The method of claim 11 including providing more cores of lower precision than cores of higher precision.

17 . One or more non-transitory computer readable media storing instructions to perform a sequence comprising:
identifying two different screen regions of one screen display; and rendering the two regions of the one screen display at different rendering rates.

18 . The media of claim 17 , further storing instructions to perform a sequence including identifying a screen region the user is currently looking at.

19 . The media of claim 17 , further storing instructions to perform a sequence including predicting a screen region that a user will look at next.

20 . The media of claim 19 , further storing instructions to perform a sequence including predicting based on a historical viewing pattern.

21 . The method of claim 19 , further storing instructions to perform a sequence including predicting based on what will be displayed in the future.

22 . The media of claim 19 , further storing instructions to perform a sequence including detecting a user's viewing pattern and using that detected pattern to predict a region that will be viewed in the future.

23 . The media of claim 17 , further storing instructions to perform a sequence including defining more than two screen regions.

24 . The media of claim 17 , further storing instructions to perform a sequence including implementing more than two render rates on the same display.

25 . The media of claim 18 , further storing instructions to perform a sequence including rendering a region the user is not currently focused on with temporal anti-aliasing and rendering another region using a different anti-aliasing technique.

26 . The media of claim 18 , further storing instructions to perform a sequence including rendering less than all the color planes in a region the user is not currently focused on.

27 . The media of claim 19 , further storing instructions to perform a sequence including tracking a moving screen object to predict which region will be viewed by the user in the future.

28 . The media of claim 17 further:
selecting assigning cores of different precision to each of at least two distinct screen regions; and
rendering each of said region with a core of different precision.

29 . The media of claim 28 , further storing instructions to perform a sequence wherein said cores are part of a common processing unit.

30 . The media of claim 29 , further storing instructions to perform a sequence wherein said cores are part of a graphics processing unit.

31 . The media of claim 28 , further storing instructions to perform a sequence wherein a core of higher precision is assigned to render a screen region of higher significance.

32 . The media of claim 31 , further storing instructions to perform a sequence wherein said region of higher significance is identified by eye gaze detection.

33 . The method of claim 31 , further storing instructions to perform a sequence including providing more cores of lower precision than cores of higher precision.

34 . An apparatus comprising:
a processor to identify two different screen regions of one screen display, and render the two regions of the one screen display at different rendering rates, and a memory coupled to said processor.

35 . The apparatus of claim 34 , said processor to identify a screen region the user is currently looking at.

36 . The apparatus of claim 34 , said processor to predict a screen region that a user will look at next.

37 . The apparatus of claim 36 , said processor to predict based on a historical viewing pattern.

38 . The apparatus of claim 36 , said processor to predict based on what will be displayed in the future.

39 . The apparatus of claim 36 , said processor to detect a user's viewing pattern and using that detected pattern to predict a region that will be viewed in the future.

40 . The apparatus of claim 34 , said processor to define more than two screen regions.

41 . The apparatus of claim 34 , said processor to implement more than two render rates on the same display.

42 . The apparatus of claim 35 , said processor to render a region the user is not currently looking at with temporal anti-aliasing and rendering another region with multi-sampled anti-aliasing.

43 . The apparatus of claim 34 , said processor to track a moving screen object to predict which region will be viewed by the user in the future.

44 . The apparatus of claim 34 , said processor to:
select assigning cores of different precision to each of at least two distinct screen regions; and render each of said region with a core of different precision.

45 . The apparatus of claim 34 , wherein said cores are part of a common processing unit.

46 . The apparatus of claim 34 , wherein said cores are part of a graphics processing unit.

47 . The apparatus of claim 44 wherein a core of higher precision is assigned to render a screen region of higher significance.
