The Sampling Pattern Cube - A Representation and Evaluation Tool for Optical Capturing Systems

Knowledge about how the light field is sampled through a camera system gives the required information to investigate interesting camera parameters. We introduce a simple and handy model to look into the sampling behavior of a camera system. We have applied this model to single lens system as well as plenoptic cameras. We have investigated how camera parameters of interest are interpreted in our proposed model-based representation. This model also enables us to make comparisons between capturing systems or to investigate how variations in an optical capturing system affect its sampling behavior.
