The plenoptic camera was originally created to allow the capture of the Light Field, a four-variable volume representation of all rays and their directions, that allows the creation by synthesis of a 3D image of the observed object. This method has several advantages with regard to 3D capture systems based on stereo cameras, since it does note need frame synchronization or geometric and color calibration. And it has many applications, from 3DTV to medical imaging. A plenoptic camera uses a microlens array to measure the radiance and direction of all the light rays in a scene. The array is placed at the focal plane of the objective lens, and the sensor is at the focal plane of the microlenses. In this paper we study the application of our super resolution algorithm to mobile phones cameras. With a commercial camera, it is already possible to obtain images of good resolution and enough number of refocused planes, just placing a microlens array in front of the detector.
