Image projection with display-condition compensation
First Claim
Patent Images
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.

Abstract
A method of projecting a compensated principal image may include projecting a principal image onto a surface and projecting an intended calibration image onto a calibration area of the surface. The intended calibration image may be projected when the principal image is not projected onto the calibration area. The calibration image displayed on the surface is received and compared to the intended calibration image to determine an observed difference. Projection of the principal image is modified based on the observed difference.

19. A display device comprising:
-
a light engine apparatus configured to project a principal image and an intended calibration image onto a display surface, the display surface disposed for viewing by one or more people, where at least a portion of the intended calibration image has an intended first color characteristic, and where the light engine apparatus includes a light engine configured to project the principal image and a calibration light unit configured to project the intended calibration image; an optical unit configured to receive a reflection from the display surface of the projected calibration image; and a processor configured to direct projection of the intended calibration image onto a calibration area of the display surface when the principal image is not projected onto the calibration area; compare the received calibration image to the intended calibration image to determine an observed difference between the intended calibration image and the received calibration image; and modify projection of the principal image based on the observed difference. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
