Abstract
A method and device for efficiently simulating lens flares produced by an optical system is provided. The method comprises the steps of - Simulating paths of rays from a light source through the optical system, the rays representing light; and Estimating, for points in a sensor plane, an irradiance, based on intersections of the simulated paths with the sensor plane.
