Abstract

A camera system for a vehicle comprising a capturing unit which comprises an optical element and image sensor with surface, to capture a section of a vehicle environment. The optical element has a distortion curve r=f(α), wherein r is the distance between an object point displayed on the image sensor surface and the intersection point of the optical axis with the image sensor surface, and α is the angle between the optical axis of the optical element and the beam incident on the optical element from the object point. The distortion curve r=f(α) has, for rw=f (αw) within 0<r<rmax, a turning point αw; rw, for which r″=f″(αw)=d2r/dα2 (αw)=0 applies, wherein rmax is the distance r=f(αmax) on the image sensor surface from the optical axis to the most distant edge of the image sensor.
