Abstract
A driver monitoring camera system for a vehicle includes a camera system and an optical beam shaper. The camera system has an exit field of view central axis oriented more vertical than horizontal with respect to a set of orthogonal x, y and z axes, where the z-axis defines a direction line indicative of a vertical direction. The optical beam shaper is disposed in optical communication with the camera system and optically between the camera system and an operator of the vehicle. The optical beam shaper is structurally configured to direct an image of a face of an operator of the vehicle toward the exit field of view of the camera system, and is structurally configured to compress the image in the vertical direction to define a compressed image having a height to width aspect ratio of less an uncompressed height to width aspect ratio of the image.
