Automatic mirror stabilization
First Claim
Patent Images
1. A method for stabilizing a first view in a mirror, the method comprising the steps of:
- identifying the first view in the mirror with respect to a first viewpoint of a user;
automatically tracking a change in viewpoint of said user to a second viewpoint; and
automatically adjusting a position of the mirror in response to said change in viewpoint so that substantially the first view is presented to said user when said user is at said second viewpoint.

Abstract
A system and a method are disclosed for automatically controlling the position of a mirror to stabilize the view in the mirror in spite of changes in viewing position. Initially, a mirror position is set by a user so that the user can comfortably view the reflection of a desired area. A tracking system estimates the user'"'"'s viewing position. As a user'"'"'s viewing position changes, the system reorients the mirror such that the reflection in the mirror is stabilized.

6. A method for maintaining a substantially constant reflection direction in a mirror despite a change from a first viewpoint to a second viewpoint, the method comprising the steps of:
-
identifying a first reflection direction in the mirror having a first position, the first reflection direction determined from the first viewpoint and the first position of the mirror;
automatically tracking a change in viewpoint from the first viewpoint to the second viewpoint; and
responsive to said change in viewpoint, automatically reorienting the mirror from said first position to a second position, wherein the second viewpoint and said second position determine a second reflection direction, wherein said second reflection direction is substantially parallel to said first reflection direction. - View Dependent Claims (7, 8, 9)

10. A system for stabilizing a first view in a mirror, the system comprising:
-
a first device positioned to observe changes in a viewing position of a user;
a control coupled to said camera; and
a mirror coupled to said control, wherein said mirror is positioned responsive to observed changes in said viewing position of said user to maintain a substantially constant first view.

11. A method of calibrating an automatic mirror stabilization system, the system comprising a first mirror, a second mirror, and a camera, the method comprising the steps of:
-
determining a transformation from a coordinate system associated with the first mirror to a coordinate system associated with the camera;
determining a transformation from a coordinate system associated with an image of the second mirror in the first mirror to said coordinate system associated with the camera;
determining a transformation from said coordinate system associated with said image of the first mirror in the second mirror to a coordinate system associated with the second mirror;
determining a transformation from said coordinate system associated with the second mirror to said coordinate system associated with the first mirror; and
determining a transformation from said coordinate system associated with the second mirror to said coordinate system associated with the camera. - View Dependent Claims (12)
