Claim 0:
1. A method for display calibration comprising:
generating an image pattern to encode display image pixels;
transmitting the image pattern to be rendered on a target display;
rendering the image pattern on a display panel of a head-mounted device (HMD);
capturing, using at least one image sensor of the HMD and through a lens of the HMD, the image pattern on the target display and the image pattern on the display panel with a same alignment as the image pattern on the target display;
determining a distortion of the image pattern resulting from the lens of the HMD based on differences between the image pattern on the target display and the image pattern on the display panel; and
providing a compensation factor for the distortion.
