Abstract
A field of view deviator apparatus for a camera lens housing on a personal communications device has a coupling that seats a removable element in a position adjacent to the camera lens and a field of view deviator prism that seats in the coupling and defines a path for image-bearing light from the subject scene to the camera lens having a first transmissive surface that is at a sufficiently oblique angle to the defined path of image-bearing light within the prism for total internal reflection, a second transmissive surface that is substantially at a normal to the defined path of incident image-bearing light within the prism; and a first reflective surface that folds the defined path of image-bearing light within the prism.
