First Claim
Patent Images
1. A method of displaying an image, the method comprising:
- A) displaying the image on a display unit, the image being in a first image position relative to a reference frame, the image being in a first image orientation relative to the reference frame, the display unit being in a first display unit position and a first display unit orientation relative to the reference frame;
B) moving the display unit to a second display unit position and/or a second display unit orientation relative to the reference frame;
C) determining the second display unit position and/or the second display unit orientation;
D) based on C), calculating a target position and/or a target orientation for at least a portion of the image relative to the display unit such that in the target position and/or the target orientation, at least the portion of the image remains substantially in the first image position and/or the first image orientation relative to the reference frame; and
E) displaying at least the portion of the image on the display unit in the target position and/or the target orientation.

Abstract
Methods and apparatus for maintaining displayed imagery stationary relative to the physical surroundings when the imagery is displayed on a display device which moves (e.g., translates and/or rotates) relative to the physical surroundings. To maintain an image'"'"'s position relative to the physical surroundings, the position of the display device may be directly measured or otherwise tracked, and the position of the imagery as displayed on the display device adjusted accordingly.

11. A system for displaying an image, the system comprising:
-
a display unit; and a controller coupled to the display unit and configured to instruct the display unit to display an image such that the image remains in substantially a same position and/or orientation, relative to physical surroundings of the display unit, notwithstanding a movement of the display unit relative to the physical surroundings. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A method of displaying an image, the method comprising:
-
A) storing information regarding an image to be displayed, wherein an image position and/or image orientation is determined with respect to a fixed reference frame; and B) progressively displaying different portions of the image, based at least in part on the stored information, via a display unit that is moving with respect to the fixed reference frame, wherein the image position and/or image orientation remains unchanged with respect to the fixed reference frame. - View Dependent Claims (19, 20)
