1. A method comprising:
controlling, by a processing system of a mobile device, an integrated camera of the mobile device to detect a plurality of fiducial markers that is displayed as part of a test pattern displayed on a display surface of a color display device to be calibrated, wherein the test pattern is one of a plurality of test patterns;
estimating, by the processing system, a position of the integrated camera relative to the display surface, using the plurality of fiducial markers;
augmenting, by the processing system, a live image of the test pattern that is visible on a display of the mobile device with an overlay;
controlling, by the processing system in response to a position of the overlay being aligned on the display of the mobile device with the live image of the test pattern, the integrated camera to capture a two-dimensional image of the test pattern; and
calculating, by the processing system, an adjustment to a color setting of the color display device, wherein the adjustment is calculated based on information extracted from the two-dimensional image.
