Security Camera System and Method of Steering Beams to Alter a Field of View
First Claim
1. A security camera system comprising:
- a lens assembly to provide at least one of a zoom view and a wide angle view;
a beam manipulating assembly disposed distally of said lens assembly and including a plurality of beam manipulating devices and corresponding rotation assemblies to rotate said beam manipulating devices relative to each other to steer an incoming beam from a surrounding environment and control a field of view of said security camera system;
an image capture device to capture images through said lens and beam manipulating devices; and
a controller to control said lens and beam manipulating assemblies to provide a desired field of view, wherein said controller includes;
a track module to identify an object within said field of view and control said beam manipulating assembly to orient said beam manipulating devices relative to each other to adjust said field of view to encompass said object in response to object motion.

Abstract
A security camera system according to present invention embodiments includes a telephoto type lens with one or more factors of optical zoom. A set of prisms that steer incoming beams from the surrounding environment (to adjust the field of view) is disposed in front of the lens. The security camera system preferably includes a wide angle staring mode that encompasses a large field of view, where the prisms are oriented to provide no steering effect. The security camera system further includes a high-resolution zoom mode, where the telephoto lens focuses on a region of interest and the prisms perform beam steering to adjust the field of view and enable the region of interest or an object to remain at the center of the security camera system view. Image processing techniques may be employed that consider the beam steering angle and the field of view to compensate for distortion effects.
