High resolution light field photography from split ray imaging and coded aperture

In this paper, we propose a method for obtaining high resolution 4D light fields by using low resolution camera sensors and controllable coded apertures. Recently, 4D light filed acquisition has been studied extensively in the field of computational photography. Since the 4D light filed consists of much lager information than the ordinary 2D image, we have to use super high resolution camera sensors in order to obtain high resolution 4D light fields. In this paper, we propose a method for obtaining high resolution 4D light fields from low resolution camera sensors. In this method, we combine the standard light field imaging technique with the coded aperture. By using these techniques, we can obtain high resolution 4D light fields from low resolution cameras with small number of image acquisitions. The efficiency of the proposed method is tested by real images.
