Abstract
An imaging apparatus comprises a first light source configured to project a first illumination onto a vehicle occupant and a second light source configured to project a second illumination onto the vehicle occupant. The system further comprises an imager comprising a pixel array. A lens apparatus comprises a first lens comprising a first field of view and a second lens comprising a second field of view. At least one shutter is selectively controlled to transmit the first illumination from the first lens to the pixel array. The at least one shutter is further controlled to selectively transmit the second illumination from the second lens to the pixel array. The imager is configured to process the first illumination in the first field of view and the second illumination in the second field of view.
