Mind the Exit Pupil Gap: Revisiting the Intrinsics of a Standard Plenoptic Camera

Tim Michels,
Daniel Mäckelmann,
Reinhard Koch

Abstract: Among the common applications of plenoptic cameras are depth reconstruction and post-shot refocusing. These require a calibration relating the camera-side light field to that of the scene. Numerous methods with this goal have been developed based on thin lens models for the plenoptic camera’s main lens and microlenses. Our work addresses the often-overlooked role of the main lens exit pupil in these models, specifically in the decoding process of standard plenoptic camera (SPC) images. We formally deduce the c… Show more
