Automatic projection focusing

摘要

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.

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; andadjusting projection of the one or more images based at least in part upon the threshold being met.
