FCam for Multiple Cameras

The Frankencamera (FCam) architecture and API enables precise control over the camera in computational photography applications.  We present an extension to FCam API for systems equipped with multiple cameras. The proposed extension allows for an enumeration of cameras and their corresponding properties, such as position or orientation.  In addition, we explicitly support camera synchronization, either through hardware mechanisms or software primitives.  If hardware synchronization is available, cameras can be grouped together under a concept of a multi-sensor.  Otherwise, multiplecamera streams are scheduled asynchronously and synchronized using our software control primitives.
