Abstract

The present invention is designed to display a matrix plane on which a time axis and an axis of applicable levels corresponding to a predetermined keyword cross each other, arrange and display identifiers indicating scenes obtained by dividing a moving image file into predetermined segments on the matrix plane and decide, when the positions of the identifiers arranged on the matrix plane are moved to desired positions, the applicable levels corresponding to the positions of the identifiers arranged on the matrix plane as the applicable levels of the scene corresponding to the identifiers. This makes it possible to improve the operability of assignment of keywords and applicable levels to a picture scene and visually check the situation of assignment of the keywords and applicable levels.

Claims

1. An authoring apparatus comprising:

a display section that displays a matrix plane on which a time axis and an axis of applicable levels corresponding to a predetermined keyword cross each other; and

a GUI processing section that displays identifiers indicating scenes obtained by dividing a moving image file into predetermined segments arranged on said matrix plane and decides, when the positions of said identifiers arranged on said matrix plane are moved, said applicable levels corresponding to the positions of said moved identifiers as said applicable levels of said scene corresponding to said identifiers.

2. The authoring apparatus according to claim 1, wherein said display control section displays, when said applicable level is assigned to said identifier, said identifier at a position on said matrix plane corresponding to said applicable level.

3. The authoring apparatus according to claim 1, further comprising an operation section that inputs said keyword, wherein said display section displays a matrix plane on which the time axis and the applicable level corresponding to said keyword input from said operation section cross each other and said GUI processing section decides the applicable level corresponding to said keyword input for said identifier.

4. The authoring apparatus according to claim 1, wherein said GUI processing section displays information showing the length of said scene near said identifier corresponding to said scene.

5. The authoring apparatus according to claim 1, wherein said GUI processing section displays a total time of a digest picture obtained by combining said scenes having levels equal to or higher than predetermined said applicable level on said matrix plane.

6. The authoring apparatus according to claim 1, wherein said GUI processing section combines, when the user performs processing of combining a plurality of said identifiers arranged on said matrix plane, said scenes corresponding to said combined identifiers and creates a new scene.

7. The authoring apparatus according to claim 1, wherein, when instructed by the user to reproduce said scene corresponding to said identifier arranged on said matrix plane and divide said scene at predetermined positions, said GUI processing section divides said scene at said predetermined positions and generates a plurality of new scenes.

8. The authoring apparatus according to claim 1, wherein when said GUI processing section decides said applicable level corresponding to said predetermined keyword for said scene divided into predetermined units corresponding to said predetermined keyword and then decides an applicable level corresponding to another keyword for the scene, each scene takes over the segmentation unit of the scene corresponding to said predetermined keyword.

9. The authoring apparatus according to claim 1, further comprising a metadata editing section that generates metadata by assigning said applicable level decided by said GUI processing section to said scene corresponding to said moved identifier.

10. The authoring apparatus according to claim 1, wherein said identifier is a representative frame image indicating a feature of said scene.

11. The authoring apparatus according to claim 9, wherein said metadata is created based on the MPEG7 standard.

15. A video editing apparatus comprising the authoring apparatus according to claim 1.

16. A home server comprising the authoring apparatus according to claim 1.

17. A video camera comprising the authoring apparatus according to claim 1.

12. An authoring apparatus comprising:

a matrix display section that displays a matrix plane on which a time axis and an axis of applicable levels corresponding to a predetermined keyword cross each other;

a moving image reproduction section that reproduces a moving image file;

a keyword display section that displays a list of a plurality of keywords;

a keyword selection section that selects a predetermined keyword from among said plurality of keyword;

a keyword start section that starts to assign said predetermined keyword to said moving image file;

a keyword stop section that stops assignment of said predetermined keyword to said moving image file;

a keyword assignment section that converts, when there is an input from said keyword start section and said keyword stop section during reproduction of said moving image file, said moving image file corresponding to the segment between the input from said keyword start section and the input from said keyword stop section to a scene and assigns said predetermined keyword to said scene; and

a GUI processing section that arranges and displays identifiers indicating said scene on said matrix plane and decides, when the positions of said identifiers arranged on said matrix plane are moved, said applicable levels corresponding to the positions of said identifiers as said applicable levels of said scene corresponding to said identifiers.

13. The authoring apparatus according to claim 12, wherein the lengths of said identifiers are lengths corresponding to the length of said scene.

14. The authoring apparatus according to claim 12, wherein said keyword display section displays keywords in colors which differ from one keyword to another or with shading and said identifiers are displayed in the colors or in the shading display mode used for said corresponding keywords.

18. An authoring method comprising:

displaying a matrix plane on which a time axis and an axis of applicable levels corresponding to a predetermined keyword cross each other;

arranging and displaying identifiers indicating scenes obtained by dividing a moving image file into predetermined segments on said matrix plane; and

deciding, when said identifiers arranged on said matrix plane are moved, said applicable levels corresponding to the positions of said identifiers arranged on said matrix plane as said applicable levels of said scene corresponding to said identifiers.

19. A program that causes a computer to display a matrix plane on which a time axis and an axis of applicable levels corresponding to a predetermined keyword, arrange and display identifiers indicating scenes obtained by dividing a moving image file into predetermined segments on said matrix plane and decide, when said identifiers arranged on said matrix plane are moved, said applicable levels corresponding to the positions of said identifiers as said applicable levels of said scene corresponding to said identifiers.

20. A storage medium storing the program according to claim 19.
