Patent ID: 6963375

Claim:
An apparatus for varying a field of view of a camera having a panning mirror rotationally coupled to an objective of the camera for bending an optical input path to align with an optical axis of the objective, and for panning the optical input path about the optical axis, and the improvement comprising: a tilt element rotationally coupled to the objective of the camera for concentric rotation aligned with the optical input path of the panning mirror about the optical axis and the tilt element having at least a first optically reflective planar surface and a second optically reflective convex surface displaced from one another arcuately about an axis of rotation of the tilt element; and a driving device coupled to the tilt element for driving arcuate rotation of the tilt element about the axis of rotation of the tilt element to effect either a selection of a reflective surface by rotating a corresponding one of at least the first optically reflective planar surface and second optically reflective convex surface into the optical input path of the panning mirror, or a tilting of the selected field of view by tilting about the axis of rotation of the tilt element of a selected one of the at least first and second optically reflective surfaces.
