With　the　advances　in　commercial　light　field　cameras,　light　field　image　processing　has　attracted　considerable　attention　from　researchers.　In　this　paper,　we　propose　a　novel　method　for　generating　stereoscopic　images　from　a　light　field　image　pair　with　flexible　control　over　the　convergence　of　the　virtual　stereo　cameras.　We　have　developed　a　light　field　image-capturing　prototype　that　consists　of　two　horizontally　arranged　light　field　cameras　(i.e.,　with　their　optical　axes　being　parallel　to　each　other).　When　using　our　proposed　device　for　image/video　capture,　stereo　photographers　can　concentrate　on　how　to　capture　the　desired　visual　experience　without　being　frequently　disturbed　by　having　to　manipulate　the　stereo　camera　parameters,　i.e.,　the　convergence　angle　of　a　stereo　camera.　During　postprocessing,　our　method　estimates　accurate　disparity　maps　for　the　light　field　image　pair　and　then　generates　the　target　stereoscopic　images　that　satisfy　the　desired　stereo　camera　convergence　requirements　by　adopting　a　novel　view　synthesis　method　for　light　field　images.　We　have　conducted　extensive　experiments　to　demonstrate　the　effectiveness　of　our　proposed　method.
