Abstract
A 3D stereo image of a scene is generated by generating first image data of the scene using light field data representing light rays from a first direction, and second image data of the scene using light field data representing light rays from a second direction. The 3D stereo image of the scene is then generated using the first image data and the second image data. A microlens array may be used to direct light rays onto a photosensor array, wherein each microlens of the microlens array includes a physical aperture which correlates to a plurality of associated photosensors, a first virtual aperture which correlates to a first subset of the associated photosensors, and a second virtual aperture which correlates to a second subset of the associated photosensors. Each virtual aperture thus provides light rays from a different direction for use in generating the 3D stereo image.
