Enhanced image capture
Disclosed are techniques that provide a “best” picture taken within a few seconds of the moment when a capture command is received (e.g., when the “shutter” button is pressed). In some situations, several still images are automatically (that is, without the user's input) captured. These images are compared to find a “best” image that is presented to the photographer for consideration. Video is also captured automatically and analyzed to see if there is an action scene or other motion content around the time of the capture command. If the analysis reveals anything interesting, then the video clip is presented to the photographer. The video clip may be cropped to match the still-capture scene and to remove transitory parts. Higher-precision horizon detection may be provided based on motion analysis and on pixel-data analysis. |

In accordance with the techniques presented herein, a requesting device broadcasts an action invitation to the device set. Each device provides a suitability report indicating its suitability to perform the action. The requesting device identifies one or more suitable devices, and sends an action request to identified devices to perform the action. |
