1. A method performed by an image display system, the method comprising:
- identifying a first arbitrary feature that is inherent in a first image frame and suitable for use as a first fiducial mark when the first image frame is displayed on a display surface by a display device; and
updating correspondence information between the display device and an image capture device using the first arbitrary feature in the first image frame and an image that is captured to include the first arbitrary feature on the display surface.

Abstract
A method performed by an image display system is provided. The method includes identifying a first arbitrary feature that is inherent in a first image frame and suitable for use as a first fiducial mark when the first image frame is displayed on a display surface by a display device and updating correspondence information between the display device and an image capture device using the first arbitrary feature in the first image frame and an image that is captured to include the first arbitrary feature on the display surface.

10. An image display system comprising:
-
a processing system configured to generate first and second sub-frames corresponding to a first image frame such that the first sub-frame includes a first region configured to cause a first feature of the first image frame to be displayed and the second sub-frame includes a second region that at least partially overlaps with the first region on the display surface and is not configured to cause the first feature to be displayed; first and second projectors configured to simultaneously project the first and the second sub-frames onto a display surface in at least partially overlapping positions; and an image capture device configured to capture an image to include the first feature as displayed on the display surface; wherein the processing system is configured to update first correspondence information between the first projector and the image capture device using the first feature in the image. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A program product comprising:
-
a program executable by a processing system for causing the processing system to; identify an arbitrary feature that is inherent in a image frame that is suitable for use as a fiducial mark when the image frame is displayed on a display surface; and generate a first correspondence between the arbitrary feature in the image frame and the arbitrary feature in an image captured from the display surface; a medium for storing the program. - View Dependent Claims (18, 19, 20)
