Abstract

A user interface is described for an image computing workstation for electronically arranging the components of a special effects job, such as image-compositing, from a plurality of image sequences obtained by the scanning of motion picture film. The interface controls the ordering of a plurality of image sequences into a hierarchy of background and foreground image sequences, with each sequence being composed of frames whose appearance imitates the frames of a motion picture film. The hierarchical image sequences are displayed adjacent to each other in a windowing environment so that the frames thereof visually align on a frame-to-frame basis. The interface includes means for varying the hierarchical order and the adjacency of the image sequences so that different frames thereof are brought into visual alignment with each other, whereby the image sequences are correctly ordered as to hierarchy and adjacency for a special effect. As an additional feature, the interface provides a flow diagram for specifying the type and order of special effect operations applied to each frame.

Claims

1. A user interface system for electronically arranging the components of a special effects job for a motion picture production from a plurality of image sequences obtained by the scanning of motion picture film, said system comprising:

a) a virtual light box interface for lining up the components of the special effects job, said virtual light box interface comprising;

means for ordering a plurality of image sequences into background and foreground image sequences, each sequence being composed of frames that imitate the frames of a motion picture film;

means for displaying the image sequences adjacent to each other so that the frames thereof visually align on a frame-to-frame basis; and

means providing for user variation of the adjacency of the image sequences so that different frames thereof are brought into visual alignment with each other, such that the image sequences are ordered by the user as to adjacency for one or more special effects; and

b) a flow graph interface visually displaying the type and order of special effects-process operations applied to the frames, said flow graph interface providing for user specification and control of what operations are to be performed and in what order the operations are applied to the components of the special effects job.

2. A system as claimed in claim 1 wherein said virtual light box interface includes an additional image sequence with additional frames, and wherein said ordering means includes ordering the additional image sequence into a hierarchy of background, foreground, and additional image sequences, the additional frames forming an image sequence in which a special effect is displayed.

3. A system as claimed in claim 2 wherein said image sequences include a background sequence and a plurality of foreground sequences ordered into a hierarchy that illustrates a special effects priority of the foreground sequences, said means providing for user variation of the adjacency of the image sequences also providing for user variation of the hierarchy of the foreground image sequences so that the priority of the foreground sequences can be changed by the user.

4. A system as claimed in claim 1 further including means for partitioning the background and foreground sequences into a plurality of image partitions each being designated for a respective special effect.

5. A system as claimed in claim 4 wherein said displaying means only displays the first and last frame of each image partition.

6. A system as claimed in claim 1 wherein said image sequences are displayed via said virtual light box interface in a window in a windowing environment.

7. A system as claimed in claim 6 wherein said displaying means is operable in a plurality of zoom modes, each mode displaying a different number of frames of each image sequence within the window.

8. A user interface system for electronically arranging the components of a special effects job for a motion picture production from a plurality of image sequences obtained by the scanning of motion picture film, said system comprising:

means for ordering a plurality of image sequences into a hierarchy of background and foreground image sequences, each sequence being composed of frames that imitate the frames of a motion picture film;

means for displaying the hierarchical image sequences adjacent to each other so that the frames thereof visually align on a frame-to-frame basis;

means providing for user variation of the adjacency of the image sequences so that different frames thereof are brought into visual alignment with each other, whereby the image sequences are ordered by the user for a special effect;

means for generating and displaying an additional image sequence with additional frames, wherein said ordering means includes means for ordering the additional image sequence into a hierarchy of background, foreground, and additional image sequences, and the additional frames form an image sequence in which the special effect is displayed; and

means providing for user specification and control and visual display of the type and order of special effects operations applied to each frame of the background and foreground image sequences.

9. A system as claimed in claim 8 wherein said image sequences include a background sequence and a plurality of foreground sequences ordered into a hierarchy that illustrates a special effects priority of the foreground sequences, said adjacency varying means further including means for user variation of the hierarchical arrangement of the image sequences so that the illustrated priority of the foreground sequences can be changed by the user.

10. A system as claimed in claim 8 further including means for partitioning the background and foreground sequences into a plurality of image partitions each being designated for a respective special effect.

11. A system as claimed in claim 8 wherein said means providing for user specification and control and visual display includes means for interactively establishing and displaying a flow diagram having interconnected special effects-process icons.

12. An interface method for electronically visualizing a special effects job for a motion picture production from a plurality of image sequences obtained by the scanning of motion picture film, said method comprising the steps of:

a) lining up the image sequences into components of the special effects job, the lining up step comprising;

ordering a plurality of image sequences into a hierarchy of background and two or more foreground image sequences, each sequence being composed of frames that imitate the frames of a motion picture film;

displaying the hierarchical image sequences adjacent to each other so that the frames thereof visually align on a frame-to-frame basis;

user variation of the adjacency of the image sequences so that different frames thereof are brought into visual alignment with each other, whereby the image sequences are ordered by a user as to adjacency for a special effect; and

displaying an additional image sequence representative of the special effect for the ordered image sequences; and

b) user specifying and visual displaying of the type and order of special effects-process operations applied to the frames, thereby showing what operations are to be performed and in what order the operations are to be applied to the components of the special effects job.

13. An interface method as claimed in claim 12 further including the step of partitioning the background and foreground sequences into a plurality of image segments each being designated for a special effect.

14. An interface method as claimed in claim 12 further including the step of providing for user changing of the hierarchical arrangement of the foreground image sequences relative to the background image sequence, whereby the image sequences are ordered by the user as to hierarchy for a special effect.
