Abstract
Techniques are disclosed for automatically calibrating content shown on an electronic display. According to certain embodiments, a picture of the display is taken while a calibration image is shown on the display. The picture is then analyzed to determine whether any adjustments need to be made. The analysis can, for example, include a comparison between the picture of the calibration image and a stored calibration image. If it is determined an adjustment needs to be made to correct how content is shown on the display, an adjustment is made accordingly.
Claims20
A method for automatically calibrating content shown on an electronic display, the method comprising:
- causing a calibration image to be shown on the electronic display, the displayed calibration image having one or more calibration elements;
- receiving, via an input interface, a first captured image of the electronic display, the first captured image including a representation of the displayed calibration image;
- comparing the representation of the displayed calibration image with a stored calibration image;
- determining that a position of at least one calibration element of the displayed calibration image is not located at a certain position of the electronic display;
- calculating, using a processor, an amount of adjustment based on the position of the at least one calibration element;
- and
- adjusting the content shown on the electronic display based, at least in part, on the amount of adjustment.
A system for automatically calibrating content shown on an electronic display, the system comprising:
- an output interface configured to be communicatively coupled with the electronic display;
- a communication interface configured to receive one or more captured images;
- a processing unit coupled with the communication interface and the output interface;
- and
- a memory communicatively coupled with and readable by the processing unit and having stored therein processor-readable instructions which, when executed by the processing unit, cause the processing unit to:
- output, via the output interface, a calibration image to be shown on the electronic display, the displayed calibration image having one or more calibration elements;
- receive, via the communication interface, a first captured image of the electronic display, the first captured image including a representation of the displayed calibration image;
- compare the representation of the displayed calibration image with a stored calibration image;
- determine that a position of at least one calibration element of the displayed calibration image is not located at a certain position of the electronic display;
- calculate an amount of adjustment based on the position of the at least one calibration element;
- and
- adjust, via the output interface, the content shown on the electronic display based, at least in part, on the amount of adjustment.
A method for automatically calibrating content shown on an electronic display, the method comprising:
- sending, via a wireless interface, instructions to cause an electronic display to output a calibration image, the displayed calibration image having one or more calibration elements;
- capturing, with a camera, a first captured image of the electronic display, the first captured image including a representation of the displayed calibration image;
- comparing the representation of the displayed calibration image with a stored calibration image;
- determining that a position of at least one calibration element of the displayed calibration image is not located at a certain position of the electronic display;
- calculating, using a processor, an amount of adjustment based on the position of the at least one calibration element;
- and
- sending, via the wireless interface, instructions to cause the content shown on the electronic display to be adjusted based, at least in part, on the calculated amount of adjustment.
