METHODS AND APPARATUS FOR FULL-RESOLUTION LIGHT-FIELD CAPTURE AND RENDERING

Method and apparatus for full-resolution light-field capture and rendering. A radiance camera is described in which the microlenses in a microlens array are focused on the image plane of the main lens instead of on the main lens, as in conventional plenoptic cameras. The microlens array may be located at distances greater than f from the photosensor, where f is the focal length of the microlenses. Radiance cameras in which the distance of the microlens array from the photosensor is adjustable, and in which other characteristics of the camera are adjustable, are described. Digital and film embodiments of the radiance camera are described. A full-resolution light-field rendering method may be applied to light-fields captured by a radiance camera to render higher-resolution output images than are possible with conventional plenoptic cameras and rendering methods.
