Abstract:
1. A method of projecting an image with display-condition compensation, the method, comprising: projecting a principal image onto a principal area of a display surface, the display surface disposed for viewing by one or more people; projecting an intended calibration image onto a calibration area of the display surface when the principal image is not projected onto the calibration area, the calibration area forming a subunit of the principal area; receiving a reflection from the display surface of the projected calibration image; comparing the received calibration image to the intended calibration image to determine an observed difference; and modifying projection of the principal image based on the observed difference; where projecting a principal image includes projecting a principal image without a portion of the principal image corresponding to the calibration area, and projecting a calibration image includes projecting the calibration image onto the calibration area while projecting the principal image without the portion.
