Abstract :
In this paper we deal with the problem of acquiring a scene light field using a programmable coded aperture camera when the angular observations are out-of-focus. We describe a portable programmable coded aperture prototype that can be attached to any DSLR camera lens and propose a blind deconvolution method to deblur light fields. The performance of the proposed method is evaluated on synthetic and real images.
