Extracting Multi-View Images from Multi-Focused Plenoptic Camera

Abstract

The multi-focused plenoptic camera is a powerful device that captures an light field (LF), which is interpreted as a set of dense multi-view images. The camera has potential ability such that we can obtain LFs having high spatial/view resolution and deep depth-of-field. Due to its effectiveness, this camera design attracted attention in vision and graphics fields. To extract multi-view images, we need a sophisticated rendering process due to its complicated optical system. However, there are few studies on this. Furthermore, the only available rendering software to the best of our knowledge has not worked well in several camera configurations. We therefore introduce an improved rendering method and will release the software that uses the method. Our software can produce better LFs than the previous one and robustly work in various camera configurations. We thus believe that our work can contribute to the computer vision and graphics community.
