Automatic projection focusing
First Claim
Patent Images
1. A method comprising:
- under control of one or more computing systems configured with specific executable instructions,projecting one or more images on a surface within an environment;
capturing image information from the environment;
based at least in part on analyzing the captured image information, determining at least one region in the projected one or more images that is to be monitored;
based at least in part on analyzing the captured image information, monitoring the at least one region in the projected one or more images for a threshold of a change in an image attribute associated with the at least one region; and
adjusting projection of the one or more images based at least in part upon the threshold being met.

Abstract
Techniques are described for performing automatic focusing of a projected image on a mobile projection surface. Specific regions of the projected image are identified that are likely to be desired to stay in optimal focus, and attributes of those specific regions, such as sharpness and contrast, can be used to determine the need to refocus the image. Advanced knowledge of the image data being projected can be utilized to determine the specific regions of the projected image that require monitoring for optimal focusing.

9. One or more non-transitory computer readable media storing computer-executable instructions executable by one or more processors to cause the one or more processors to:
-
cause a projector to project a one or more images on a surface within an environment; capture image information from the environment; based at least in part on analyzing the captured image information, determine at least one region in the projected one or more images that is to be monitored; based at least in part on analyzing the captured image information, monitor the at least one region in the projected one or more images for a threshold of a change in an image attribute associated with the at least one region; and adjust projection of the one or more images based at least upon the threshold being met. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A system comprising:
-
one or more processors; a camera; a projector; and one or more non-transitory computer-readable storage media storing computer-executable instructions that are executable by the one or more processors to cause the one or more processors to; cause the projector to project one or more images to be displayed on a surface of an environment; capturing image information from the environment; based at least in part on analyzing the captured image information, determine at least one region in the projected one or more images that is to be monitored; based at least in part on analyzing the captured image information, monitor the at least one region in the projected one or more images for a threshold of a change in an image attribute associated with the at least one region; and adjust projection of the one or more images based at least in part upon the threshold being met. - View Dependent Claims (18, 19, 20, 21, 22, 23)
