Abstract
In a camera unit, a lens system may be configured by a first lens group (wide-angle lens system) whose a field angle in a horizontal direction is 120 degrees or more, a second lens group (anamorphic lens system) whose anamorphic ratio is 1.5 or more, and a third lens group (image-forming lens system). A lens system may be configured so that the amount of change in image height with respect to a change of an image angle is made larger at the peripheral parts than at the center portion of a formed image.
