Abstract

A method is provided in one example and includes displaying a calibration area surrounded by a background on a display; analyzing an image of the calibration area to determine if the background is detectable in the image; adjusting the calibration area until at least a portion of the background is not detectable; and storing the adjustment for the calibration area. In more particular examples, the method may include determining a percentage of the background that is detectable; and adjusting the calibration area based on the percentage. In yet other instances, the method may include decreasing a size of the calibration area if the size of the calibration area is bigger than the display.

Claims

1. A method implemented by an apparatus, the method comprising:

displaying a calibration area surrounded by a background on a display;

analyzing an image of the display to determine a ratio of an area of the calibration area to an area of the background;

expanding the calibration area by a factor greater than one, if the ratio of the area of the calibration area to the area of the background is less than one;

expanding the calibration area by a factor less than one, if the ratio of the area of the calibration area to the area of the background is greater than or equal to one;

adjusting the calibration area until at least a portion of the background is not detectable; and

storing an adjustment for the calibration area.

4. The method of claim 1, further comprising:

decreasing a size of the calibration area if the size of the calibration area is bigger than the display.

5. The method of claim 1, further comprising:

receiving a signal from a mobile device indicating that the background is detectable.

6. The method of claim 1, wherein the background is not detectible if the area of the background is less than two percent of an area of the display.

14. The method of Claim 1 wherein the apparatus is a set-top box configured to interact with a handset for adjusting the calibration area until the portion of the background is not detectable.

18. The method of Claim 1 wherein the apparatus is a console element configured to interact with a mobile device for adjusting the calibration area until the portion of the background is not detectable.

19. The method of claim 1, further comprising:

analyzing the image of the display for a color indicative of an area for rendering content on the display.

2. Logic encoded in one or more non-transitory media that includes code for execution and when executed by a processor is operable to perform operations comprising:

displaying a calibration area surrounded by a background on a display;

analyzing an image of the calibration area to determine if the background is detectable in the image;

determining a percentage of the background that is detectable;

adjusting the calibration area based on the percentage;

adjusting the calibration area until at least a portion of the background is not detectable; and

storing an adjustment for the calibration area.

3. A method, comprising:

displaying a calibration area surrounded by a background on a display;

analyzing an image of the calibration area to determine if the background is detectable in the image;
