Summary

Obtaining a light field from real world the can enable many applications, such as post-capture camera control and scene reconstruction. While many light field capture systems have been proposed and built in the lab, the microlens/lenslet-based approach is still the most mature one and already available on the market. However, it is often stated that there is a fundamental tradeoff between spatial and angular resolution of lenslet light field cameras, but there has been limited understanding of this tradeoff theoretically or numerically. This talk will describe a light transport framework for understanding the fundamental limits of light field camera resolution. 

The new framework includes many factors that were not included in existing models. For example, we show that the 4D spatial-angular sensitivity profile of the photosensor must be considered in the performance analysis. The new framework is used to make many predictions that are closer to the observations and contradict existing models. The talk will discuss how the new framework should be considered in designing the light field cameras or processing algorithms.
