Abstract
An illumination reproduction apparatus and process for illuminating a subject with the illumination at a location in a scene when the subject is not in the scene. Scene illumination data is generated that specifies the illumination at the location in the scene from a plurality of spatial directions. The subject is then illuminated with the illumination at the location in the scene by driving a plurality of light sources surrounding the subject with the scene illumination data.
Claims29
An illumination reproduction process for illuminating a real subject with the illumination at a location in a scene when the real subject is not in the scene comprising:
- a) generating scene illumination data specifying the illumination at the location in the scene from a plurality of spatial directions;
- and
- b) illuminating the real subject with the illumination at the location in the scene by driving a plurality of real light sources surrounding the real subject with the scene illumination data.
An illumination reproduction process for illuminating a real subject with the illumination at a location in a scene when the real subject is not in the scene comprising illuminating the real subject with the illumination at the location in the scene by a plurality of real light sources surrounding the real subject being driven with scene illumination data specifying the illumination at the location in the scene from a plurality of spatial directions.
An illumination apparatus for illuminating a subject with the illumination at a location in a scene when the subject is not in the scene comprising:
- a) a plurality of light sources surrounding the subject;
- b) a driver in communication with said light sources for driving said light sources with scene illumination data specifying the illumination that the scene provides at the location in the scene from a plurality of spatial directions.
An image compositing system for producing an image of a scene containing a subject that was not photographed in the scene, but illuminated as though the subject was in the scene, comprising:
- a) an illumination apparatus for illuminating the subject based on scene illumination data specifying the illumination that the scene provides at a location in the scene at which the subject is to be illuminated from a plurality of spatial directions;
- b) a camera for photographing the subject while illuminated by said illumination apparatus;
- and
- c) a compositing system for compositing the photograph of the subject from said camera in the scene.
