Light fields can be captured by plenoptic cameras and observed on integral displays supporting auto-stereoscopic viewing and full parallax. However due to the limited aperture of plenoptic cameras and the resampling process needed to overcome the resolution mismatch between the capturing and displaying devices, the perceived parallax of the resampled light fields is considerably reduced, limiting the viewing experience. We propose a light field retargeting technique that enhances the perceived parallax by first slicing the captured light fields according to their disparity, and then translating these slices with proper magnitudes and directions prior to the resampling stage. The resampled light field conserves enough parallax to be perceived in the target display. The developed technique gives users control over the depth of field and the axial location of the rendered objects as seen through the integral display.
