Methods and systems for content processing

摘要

Disclosed are technologies are useful in enabling a smart phone to respond to a user's environment, e.g., so it can serve as an intuitive hearing and seeing device. Some of the detailed arrangements involve using radio base station SDR equipment (e.g., at a cell tower) to perform image recognition operations for phones; forecasting service needs from remote processors delegating a remote execution task to a service provider chosen in a competitive process; using nearby processors, e.g., in an automobile, another phone, or set-top box, for remote execution tasks; phones with separable camera and/or illumination components; phone camera illumination using different colors of light; using search tree methods with image frames captured at different focuses; using a phone's microprojector to aid in object identification; correcting lens aberrations by texture mapping captured imagery onto a corrective polygon surface using a phone GPU; etc. A great variety of other features are also detailed.

主权项

1. A method comprising:
(a) using a camera sub-system of a mobile phone, capturing and buffering plural frames of image data, while the camera sub-system is changing a parameter that varies a camera focal distance from a first focal distance to a second focal distance, thereby yielding frames of image data at a variety of focal distance settings; (b) performing a first analysis on one or more of said frames of image data, to assess a focus parameter; (c) based on said first analysis, selecting one of said captured and buffered plural frames of image data, not analyzed in act (b), as having a desired focus parameter; and (d) taking a further action with the selected frame of image data; wherein said selected frame was captured before said first analysis was performed, but was not selected until after said first analysis was performed.
