Abstract

A method for applying user experience effects to a displayed image. The method may sample data from sensors and create a profile based on the sampled data. The method may use the profile to alter the displayed image to reflect the environment of a computing system.

Claims

1. A method for changing an image on a computing system, comprising:

measuring light data using at least two measurement devices;

receiving data from the at least two measurement devices;

creating a spatial ambient light profile based on at least the received data; and

altering the image displayed on a computing system display in accordance with the spatial ambient light profile.

2. The method of claim 1, wherein measuring light data further comprises measuring environmental lighting conditions.

3. The method of claim 1, further comprising determining the direction of a light source.

4. The method of claim 2, further comprising applying effects to the image displayed on the computing system to simulate the environmental lighting conditions.

5. The method of claim 4, further comprising reflecting a time of day in the image.

6. The method of claim 1, further comprising determining the predominant wavelength of a light source.

7. The method of claim 3, wherein altering the image further comprises shading the image to simulate the effect of the light source on the image.

8. The method of claim 6, wherein altering the image further comprises applying a color profile based on at least the predominant wavelength of the light source.

9. The method of claim 1, further comprising filtering data noise by periodically sampling the sensor data.

10. The method of claim 1, wherein altering the image further comprises applying effects to images selected by at least one of a user or an operating system.

11. The method of claim 10, wherein altering the image further comprises applying contrast grading to the image.

13. The method of claim 1, further comprising determining the direction of a light source.

15. The method of claim 1, further comprising determining the predominant wavelength of a light source.

16. The method of claim 13, wherein altering the image further comprises shading the image to simulate the effect of the light source on the image.

17. The method of claim 15, wherein altering the image further comprises applying a color profile based on at least the main wavelength of a light source.

12. A method for altering an image based on an environment, comprising:

measuring ambient light using light intensity sensors;

periodically sampling measurements provided by the light intensity sensors;

providing ambient light data to a computing system;

creating a light profile based on at least the measurements provided by the light intensity sensors; and

applying effects to an image displayed on the computing system, wherein the effects are based at least on the light profile.

14. The method of claim 12, further comprising applying effects to the image displayed on the computing system to simulate environmental lighting conditions.

18. The method of claim 12, further comprising filtering data noise by periodically sampling the sensor data.

19. The method of claim 12, wherein altering the image further comprises applying effects to images selected by a user.

20. The method of claim 19, wherein altering the image further comprises applying contrast grading to the image.
