Abstract

A method for generating a brightness contribution for a picture element of an image includes providing a first data record including data which describe the effect on light rays of the lens, providing a second data record including data about a point of incidence of a light ray on the image recorder and about a virtual front surface, providing a transformation rule, calculating a first point of intersection of the light ray with the virtual front plane and a direction of the light ray at the first point of intersection by applying the transformation rule to the first and second data records, determining the brightness contribution of the light ray, storing an information item regarding the calculated brightness contribution. The first data record includes data about a second surface and the second data record includes data about a second point of intersection of the light beam with the second surface.
