Abstract

Plenoptic camera provides us with the capability of refocusing photograph and extending the depth of field(DOF) after exposure. But when we render image patch by patch, the output image is rendered with visible artifacts because of mismatch of the adjacent patch boundaries. The paper introduce a novel image rendering algorithm based on the focused plenoptic camera. The algorithm extracts the depth information from the raw light field data, and then render the result image patch by patch based on the depth map. The algorithm can export an image setting in a desirable focus. It can also extend the depth of field to the case that the whole scene in the image is in focus. And from the simulation, it can be learnt that comparing with the traditional algorithm, the artifacts in the rendering result are suppressed significantly to a sightless level.
