Abstract: Approaches are described for constructing a single camera by combining an array (or other arrangement) of multiple smaller and lower resolution cameras. Each of the smaller cameras is aimed in a different direction in order to provide a wider angle and higher resolution field of view (FOV) for the resulting composite camera. Images captured by all of the cameras in the array can be stitched together using software to produce a single composite photograph. This construction method can enable the camera unit to be thinner and potentially cheaper in construction costs than an equivalent single-piece camera that has been conventionally implemented in portable devices.

Abstract: Systems and methods for profiled and focused searching of litigation information allow a user to access specific legal information for use during litigation.
