Abstract

In a computerized film (digital camera action) production system, a virtual director module takes responsibility for creating sets, and enabling cinematography by creating a synthetic parallax matching of a “set” image to what would have existed before a camera in real motion about the physical location represented. This overcomes failures typical of “green screen” technology in dealing with such conditions as shallow depth of field and low light. Computer generated, synthetic sets from a 3D animator may be projected behind real actors during or after filming. Sythetic sets are seen through a virtual camera as photo-realistic because they are skinned with textures, and structured geometrically, to match reality represented by actual still photography of a physical environment, such as buildings, walls, streets, landscapes, props, and the like.

Claims

1. A method for cinematography comprising:

providing a synthetic set comprising set images stored in digital data representing a scene comprising images of physical objects;

directing action before a camera, creating a moving picture comprising a sequence of photographs, while actors being photographed and a camera taking the photographs are both moving;

recording, by the camera, from a viewing angle that changes with time, the action into a recording of the action; and

creating a movie scene having the recording and the synthetic set each integrated to display the synthetic set and the action continually from the same perspective, corresponding to the viewing angle of the camera.

2. The method of claim 1, wherein the synthetic set has a physical geometry representing an actual physical location.

3. The method of claim 2, wherein the synthetic set comprises images digitally constructed to represent the actual physical location.

4. The method of claim 2, further comprising generating the synthetic set based on a still photograph of the physical location.

5. The method of claim 4, further comprising calculating by a processor, physical dimensions of the physical location, based on at least one of dimensions and perspective of the still photograph.

6. The method of claim 5, further comprising, creating a digitally stored image of a texture copied from the still photograph.

7. The method of claim 6, further comprising generating the set image by creating a synthetic image using the dimensions, perspective, and texture.

8. The method of claim 7, further comprising rendering the set image in real time, corresponding to the action, from the perspective of the camera during the action.

9. The method of claim 8, further comprising programming the processor to create the set image by generating a model of the physical location based on an input from the camera.

10. The method of claim 9, further comprising projecting the set image onto a screen behind the action and before the camera during the action.

12. The system of claim 1, further comprising:

a screen receiving a projection of, and displaying, a background image representing the synthetic set during the recording;

the camera, including in the recording the background image.

13. The system of claim 12, wherein the screen is a rear-projection screen.

11. A system comprising:

a camera, configured to record a continual stream of images of actors in motion, constituting a motion picture;

a processor operably connected to share information with the camera;

a tracking device operably connected to the camera and the processor to record motion and a viewing angle of the camera and provide corresponding motion data and viewing angle data to the processor;

the processor programmed with a director module generating a synthetic set corresponding to an image representing a physical environment, time-varying to correspond to the moving picture; and

the processor, further programmed to select a perspective for the synthetic set corresponding to the viewing angle and motion;

the processor, further programmed to to generate the synthetic set to appear as if recorded by the camera from the viewing angle and motion.

14. The system of claim 11, wherein the processor is further programmed to to create a hybrid movie by adding a background image representing the synthetic set to the motion picture.

15. The system of claim 14, further comprising a projector programmed to project the hybrid moving on a display screen visible to viewers.
