Abstract:
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.
