Mobile device case and techniques for multi-view imaging
Described herein are embodiments of a mobile device case that allows a mobile device camera to view and/or capture images from multiple fields of view. The case may allow the mobile device camera to simultaneously capture image information from multiple different directions relative to the camera or mobile device. The fields of view may not be contiguous fields of view, such that there is a gap or other discontinuity between the fields of view. One field of view may be a field visible from or facing a surface of the mobile device on which the camera is disposed (e.g., the back of the mobile device) and another field of view may be one visible from or facing a different surface of the mobile device. Also described are embodiments of techniques for configuring a mobile device to capture and/or process images from multiple fields of view.
