Abstract
A light field data acquisition device includes optics and a sensor to acquire light field image data of a scene. In at least one embodiment, the sensor is located at a substantially fixed, predetermined location relative to the focal point of the optics. The device determines a first virtual focus depth different from an optical focus depth of the light field image data, and automatically generates and outputs data representative of a first image of the scene at the first virtual focus depth. In response to user input, the device determines a second virtual focus depth and generates data representative of a second image of the scene at the second virtual focus depth.
