  We assess the accuracy of a smartphone camera simulation. The simulation is
an end-to-end analysis that begins with a physical description of a high
dynamic range 3D scene and includes a specification of the optics and the image
sensor. The simulation is compared to measurements of a physical version of the
scene. The image system simulation accurately matched measurements of optical
blur, depth of field, spectral quantum efficiency, scene inter-reflections, and
sensor noise. The results support the use of image systems simulation methods
for soft prototyping cameras and for producing synthetic data in machine
learning applications.
