+ The camera physical mounting rotation. It is expressed as the angular

+ camera module, and one defined on the external world scene to be
+ captured when projected on the image sensor pixel array.
A camera sensor has a 2-dimensional reference system 'Rc' defined by
its pixel array read-out order. The origin is set to the first pixel
