In this paper, we propose a method to extract light field using a conventional camera from a single image capture. The method involves an offline calibration process, where point spread functions, relating different perspective images captured with a narrow aperture to a central image captured with a wide aperture, are estimated for different depths. During application, light field perspective images are recovered by de-convolving the input image with the set of point spread functions that were estimated in the offline calibration process.
