Abstract
A light field camera capturing one or more light field frames including intensity and angle information of received light. The light field camera includes an array of pixels, a liquid crystal layer overlaying the array of pixels, and a controller. The controller controls, at each time instant, one or more voltages applied to the liquid crystal layer. The controller adjusts, based on the one or more voltages, the liquid crystal layer to control amounts of light at one or more angles transmitted through the liquid crystal layer and captured by the array of pixels as a light field frame. The controller can determine depth information based on the captured one or more light field frames.
