Validation of image systems simulation technology using a Cornell Box

We describe and experimentally validate an end-to-end simulation of a digital camera. The models the spectral radiance 3D-scenes, formation irradiance by multi-element optics, conversion to values image sensor. quantify accuracy comparing real simulated images precisely constructed, three-dimensional high dynamic range test scene. Validated software camera can accelerate innovation reducing many time-consuming expensive steps in designing, building evaluating systems.
