Abstract

A system may allow an initial viewing adjustment curve set at a factory to be adjusted by a user, and the adjustment may pull the viewing adjustment curve in a particular direction, but may not result in a multistep, jerky viewing adjustment curve. The curve of the viewing adjustment curve may remain a curve, but, through the use of regions and smoothing, the viewing adjustment curve may retain its curve design.

Claims

1. A method of adjusting brightness on an electronic display in communication with a computing device comprising:

receiving an ambient light reading from an ambient light sensor in proximity to the electronic display;

storing the ambient light reading in a memory;

determining a viewing adjustment level based on the ambient light reading and a viewing adjustment curve;

receiving a viewing adjustment;

storing the viewing adjustment in a memory;

adjusting the viewing adjustment curve in response to the viewing adjustment comprising

separating the viewing adjustment curve into n regions based on the ambient light reading;

determining an appropriate region wherein the appropriate region comprises a region of the n regions in which the ambient light reading occurs;

creating an updated viewing adjustment curve comprising adjusting the viewing adjustment curve in the appropriate region toward the viewing adjustment while maintaining the updated viewing adjustment curve continuously across all of the n regions;

storing the updated viewing adjustment curve in a memory;

adjusting the electronic display on the electronic display based on the updated viewing adjustment curve and the ambient light reading.

2. The method of claim 1, further comprising using a smoothing algorithm on the updated viewing adjustment curve.

3. The method of claim 2, further comprising using the ambient light reading in the memory and the viewing adjustment in the memory to create a regression used in calculating the updated viewing adjustment curve.

4. The method of claim 3, further comprising averaging the updated viewing adjustment curve and the viewing adjustment curve to create a new updated viewing adjustment curve and using the new updated viewing adjustment curve to adjust the electronic display.

5. The method of claim 3, further comprising calculating a maximum value and a minimum value for the viewing adjustment curve in each region based on surrounding regions wherein the maximum value and the minimum value for the viewing adjustment curve in a first region are within a predetermined percentage of the surrounding regions.

6. The method of claim 1, further comprising storing a user and creating the updated viewing adjustment curve for each user.

7. The method of claim 1, wherein the n regions are different sizes.

8. The method of claim 1, wherein the viewing adjustment curve with the n regions has n data points, one associated with each region and the updated viewing adjustment curve is made to fit each data point.

9. The method of claim 1, wherein the viewing adjustment comprises at least one selected from a group comprising brightness, contrast, font size, font color and font bold level

10. A computer storage medium comprising computer executable instructions for adjusting brightness on an electronic display in communication with a computing device, the computer executable instructions comprising computer executable instructions for:

receiving an ambient light reading from an ambient light sensor in proximity to the electronic display;

storing the ambient light reading in a memory;

determining a viewing adjustment level based on the ambient light reading and a viewing adjustment curve;

receiving a viewing adjustment;

storing the viewing adjustment in a memory;

adjusting the viewing adjustment curve in response to the viewing adjustment comprising

separating the viewing adjustment curve into n regions based on the ambient light reading;

determining an appropriate region wherein the appropriate region comprises a region of the n regions in which the ambient light reading occurs;

creating an updated viewing adjustment curve comprising adjusting the viewing adjustment curve in the appropriate region toward the viewing adjustment while maintaining the updated viewing adjustment curve continuously across all of the n regions;

storing the updated viewing adjustment curve in a memory;

adjusting the electronic display on the electronic display based on the updated viewing adjustment curve and the ambient light reading.

11. The computer storage medium of claim 10, further comprising computer executable instructions for using a smoothing algorithm on the updated viewing adjustment curve.

12. The computer storage medium of claim 11, further comprising computer executable instructions for using the ambient light reading in the memory and the viewing adjustment in the memory to create a regression used in calculating the updated viewing adjustment curve.

13. The computer storage medium of claim 12, further comprising computer executable instructions for averaging the updated viewing adjustment curve and the viewing adjustment curve to create a new updated viewing adjustment curve and using the new updated viewing adjustment curve to adjust the electronic display.

14. The computer storage medium of claim 12, further comprising computer executable instructions for calculating a maximum value and a minimum value for the viewing adjustment curve in each region based on surrounding regions wherein the maximum value and the minimum value for the viewing adjustment curve in a first region are within a predetermined percentage of the surrounding regions.

15. The computer storage medium of claim 10, further comprising computer executable instructions for storing a user and creating the updated viewing adjustment curve for each user.

16. The computer storage medium of claim 10, wherein the n regions are different sizes and wherein the viewing adjustment curve with the n regions has n data points, one associated with each region and the updated viewing adjustment curve is made to fit each data point.

20. The computer system of claim 10, wherein the n regions are different sizes and wherein the viewing adjustment curve with the n regions has n data points, one associated with each region and the updated viewing adjustment curve is made to fit each data point.

17. A computer system comprising a processor physically configured according to computer executable instructions for adjusting brightness on an electronic display in communication with the computing system, a memory for maintaining the computer executable instructions, and an input output circuit, the computer executable instructions comprising computer executable instructions for:

receiving an ambient light reading from an ambient light sensor in proximity to the electronic display;

adjusting the viewing adjustment curve in response to the viewing adjustment comprising

separating the viewing adjustment curve into n regions based on the ambient light reading;

determining an appropriate region wherein the appropriate region comprises a region of the n regions in which the ambient light reading occurs;

creating an updated viewing adjustment curve comprising adjusting the viewing adjustment curve in the appropriate region toward the viewing adjustment while maintaining the updated viewing adjustment curve continuously across all of the n regions;

storing the updated viewing adjustment curve in a memory;

adjusting the electronic display on the electronic display based on the updated viewing adjustment curve and the ambient light reading.

18. The computer system of claim 17, further comprising computer executable instructions for using the ambient light reading in the memory and the viewing adjustment in the memory to create a regression used in calculating the updated viewing adjustment curve.

19. The computer system of claim 17, further comprising computer executable instructions for calculating a maximum value and a minimum value for the viewing adjustment curve in each region based on surrounding regions wherein the maximum value and the minimum value for the viewing adjustment curve in a first region are within a predetermined percentage of the surrounding regions.
