Abstract

A multi-focused plenoptic camera is a powerful device that can capture a 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 with high spatial/view resolutions and deep depth-of-field. To extract multi-view images, we need a sophisticated rendering process due to the complicated optical system of such cameras. However, there are few researches on this topic, and the only available rendering software to the best of our knowledge could not work well for some camera configurations. We therefore propose an improved rendering method and release our rendering software. Our software can extract multi-view images from a multi-focused plenoptic camera with higher quality than the previous one and work for various camera configurations.
