Abstract: A method includes controlling an integrated camera of a mobile device to detect a plurality of fiducial markers displayed as part of a test pattern on a display surface of a color display device, wherein the test pattern is one of a plurality of test patterns, estimating a position of the integrated camera relative to the display surface, using the plurality of fiducial markers, augmenting a live image of the test pattern on a display of the mobile device with an overlay, controlling, 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 an image of the test pattern, and calculating an adjustment to a color setting of the color display device, wherein the adjustment is calculated using information extracted from the image.
