Abstract
Techniques for performing diagnostics on an electronic display are described in various implementations. In one example implementation, a method may include receiving image data that depicts a test protocol being displayed on an electronic display, the test protocol comprising a two-dimensional barcode. The method may also include processing the image data to determine whether a message encoded in the two-dimensional barcode is corrupted. The method may also include generating a diagnostic result for the electronic display based on the determination.
Claims20
A method for performing diagnostics on an electronic display, the method comprising:
- receiving, at a computer system and from an image capture device, image data that depicts a test protocol being displayed on an electronic display, the test protocol comprising a two-dimensional barcode;
- processing the image data, using the computer system, to determine whether a message encoded in the two-dimensional barcode is corrupted;
- and
- generating, using the computer system, a diagnostic result for the electronic display based on the determination.
A mobile computing device comprising:
- one or more processors;
- an image capture device that captures an image of an electronic display to be tested;
- an image processing module, executing on at least one of the one or more processors, that processes the image and identifies a two-dimensional barcode being displayed on the electronic display;
- and
- a diagnostics module, executing on at least one of the one or more processors, that determines whether the two-dimensional barcode is legible, and if so, whether a message encoded in the two-dimensional barcode matches an expected test message.
A non-transitory computer-readable storage medium storing instructions that, when executed by one or more processors, cause the one or more processors to:
- receive an image of an electronic display to be tested;
- process the image to identify a two-dimensional barcode being displayed on the electronic display;
- determine whether the two-dimensional barcode is interpretable, and if so, whether a message encoded in the two-dimensional barcode matches an expected test message;
- and
- generate a diagnostic result based on the determination.
