High-resolution light field cameras based on a hybrid imaging system

Compared to traditional digital cameras, light field (LF) cameras measure not only the intensity of rays, but also their light field information. As LF cameras trade a good deal of spatial resolution for extra angular information, they provide lower spatial resolution than traditional digital cameras. In this paper, we show a hybrid imaging system consisting of a LF camera and a high-resolution traditional digital camera, achieving both high spatial resolution and high angular resolution. We build an example prototype using a Lytro camera and a DSLR camera to generate a LF image with 10 megapixel spatial resolution and get high-resolution digital refocused images, multi-view images and all-focused images.
