Abstract: In various embodiments, the present invention relates to methods, systems, architectures, algorithms, designs, and user interfaces for light-field based autofocus. In response to receiving a focusing request at a camera, a light-field autofocus system captures a light-field image. An image crop that contains a region of interest and a specified border is determined. A series of refocused images are generated for the image crop at different scene depths. A focus metric is calculated for each refocused image. The scene depth of the refocused image with the best focus metric is identified as the appropriate focus. The focus motor position for the appropriate focus is selected and the focus motor is automatically driven to the selected focus motor position.

Abstract: In various embodiments, the present invention relates to methods, systems, architectures, algorithms, designs, and user interfaces for capturing, processing, analyzing, displaying, annotating, modifying, and/or interacting with light-field data on a light-field capture device. In at least one embodiment, the light-field capture device communicates to the user information about the scene during live-view to aid him or her in capturing light-field images that provide increased refocusing ability, increased parallax and perspective shifting ability, increased stereo disparity, and/or more dramatic post-capture effects. Additional embodiments present a standard 2D camera interface to software running on the light-field capture device to enable such software to function normally even though the device is actually capturing light-field data.
