Digital Correction of Registration Error for the Micro Lens Array and Image Sensor in Plenoptic Camera

Abstract:

Plenoptic camera provides us with the capability of refocusing photographs after exposure and extended depth of field. But the registration error for the micro lens array and image sensor influences on the quality of extracted 4D light field and thus leads to a degradation of the reconstructed image. The paper discusses two type of registration errors based on the structure of focused plenoptic camera and proposes a correction algorithm to acquire accurate light field from the sensor data. The simulation shows that registration errors deteriorate the reconstructed image and the artifact will be reduced significantly after using the algorithm.
