Abstract
The specification and drawings present a light fixture for an imaging camera, where a protective window size requirements for camera imaging in a wide field of view (WFOV) are minimized using directional imaging through the protective window. This can be accomplished by a camera position adjustment according to a predefined algorithm as described herein. This adjustment may be performed using a mechanical motor or manually (using corresponding screws, lever, etc.) to actuate a mechanical mechanism. For example, a four-bar linkage mechanism may be used, which may allow the camera to pivot about a virtual pivot point (or generally, a pivotal area) generated by the intersection of the camera lens bore sight axes (camera lens central axes), e.g., outside of a housing of the light fixture.
