Video camera for assisting vehicle driver, has lens designed to increase coverage area in horizontal direction based on size given by aspect ratio of image sensor so that horizontal scale in boundary areas is larger than in middle area

摘要

The camera has an image sensor (3) and a lens (2). The lens is designed such that a coverage area (9) is increased in a horizontal direction based on the size given by the aspect ratio of the image sensor. The horizontal scale in the boundary areas is larger than in a middle area in relation to increase of the coverage area. The lens consists of a radial symmetrical part and a non radial symmetrical part.
