SECURITY CAMERA SYSTEM AND METHOD OF STEERING BEAMS TO ALTERA FIELD OF VIEW |
摘要 |
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 prism s 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 a t the center of the security camera system view. Image processing techniques may be employed tha t consider the beam steering angle and the field of view to compensate for distortion effects.
