Abstract

The coupling between aperture size and the depth of field (DOF) in traditional imaging remains one of the fundamental limits on photographic freedom. The emergence of the plenoptic camera imaging solves the issues. Based on the focus plenoptic camera implemented by Georgiev, we propose an all-focused image rendering algorithm which depends on the DOF. Using the raw image captured by the prototype of the camera, we successfully reconstruct an all-focused image of the scene and calculate a higher resolution depth map. Finally, we conclude that a large depth of field image can still be achieved even with a large aperture.
