Abstract

The present invention provides an apparatus capable of retrieving a moving image file and a still picture file associated therewith efficiently. The apparatus produces a still picture file including still picture data extracted from moving image data, produces a moving image file including the moving image data and information (for example, a file name) associated with the still picture file, and records the moving image file and the still picture file on a recording medium to which random access can be effected.

Claims

1. A recording apparatus comprising:

processing means for producing a still picture file including still picture data extracted from moving image data and for producing a moving image file including the moving image data and information associated with the still picture file; and

recording means for recording the moving image file and the still picture file on a recording medium.

2. A recording apparatus according to claim 1, wherein the information associated with the still picture file is a file name of the still picture file.

3. A recording apparatus according to claim 1, wherein said moving image processing means adds the information associated with the still picture file to a header of the moving image file.

4. A recording method comprising the steps of:

producing a still picture file including still picture data extracted from moving image data;

producing a moving image file including the moving image data and information associated with the still picture file; and

recording the moving image file and the still picture file on a recording medium.

5. A recording method according to claim 4, wherein the information associated with the still picture file is a file name of the still picture file.

6. A recording method according to claim 4, wherein said step for producing the moving image file adds the information associated with the still picture file to a header of the moving image file.

7. A recording apparatus comprising:

processing means for producing a moving image file including moving image data and for producing a still picture file including still picture data extracted from the moving image data and information associated with the moving image file; and

recording means for recording the still picture file and the moving image file on a recording medium.

8. A recording apparatus according to claim 7, wherein the information associated with the moving image file is a file name of the moving image file.

9. A recording apparatus according to claim 7, wherein said still picture processing means adds the information associated with the moving image file to a header of the still picture file.

10. A recording method comprising the steps of:

producing a moving image file including moving image data;

producing a still picture file including still picture data extracted from the moving image data and information associated with the moving image file; and

recording the still picture file and the moving image file on a recording medium.

11. A recording method according to claim 10, wherein the information associated with the moving image file is a file name of the moving image file.

12. A recording method according to claim 10, wherein said step for producing the still picture file adds the information associated with the moving image file to a header of the still picture file.

14. A reproducing apparatus according to claim 13, wherein said display control means displays the information indicating presence of the still picture file in the vicinity of the reduced image of the moving image file.

15. A reproducing apparatus according to claim 13, wherein said display control means displays a reduced image of the still picture file on said display device if the reduced image of the moving image file is selected.

16. A reproducing apparatus according to claim 13, wherein said detection means detects whether there is the still picture image on the basis of a header of the moving image file.

18. A reproducing method according to claim 17, wherein said displaying step displays the information indicating the presence of the still picture file in the vicinity of the reduced image of the moving image file.

19. A reproducing method according to claim 17, wherein said displaying step includes a step for displaying a reduced image of the still picture file on said display device if the reduced image of the moving image file is selected.

20. A reproducing method according to claim 17, wherein said detecting step detects whether there is the still picture file on the basis of a header of the moving image file.

13. A reproducing apparatus comprising:

detection means for detecting whether there is a still picture file associated with a moving image file; and

display control means for displaying a reduced image of the moving image file and information indicating presence of the still picture file on a display device if there is the still picture file.

17. A reproducing method comprising the steps of:

detecting whether there is a still picture file associated with a moving image file; and

displaying a reduced image of the moving image file and information indicating presence of the still picture file on a display device if there is the still picture file.

21. A reproducing apparatus comprising:

detection means for detecting whether there is a moving image file associated with a still picture file; and

display control means for displaying a reduced image of the still picture file and information indicating presence of the moving image file on a display device if there is the moving image file.

22. A reproducing apparatus according to claim 21, wherein said display control means displays the information indicating presence of the moving image file in the vicinity of the reduced image of the still picture file.

23. A reproducing apparatus according to claim 21, wherein said display control means displays a reduced image of the moving image file on said display device if the reduced image of the still picture file is selected.

24. A reproducing apparatus according to claim 21, wherein said detection means detects whether there is the moving image on the basis of a header of the still picture file.

26. A reproducing method according to claim 25, wherein said displaying step displays the information indicating the presence of the moving image file in the vicinity of the reduced image of the still picture file.

27. A reproducing method according to claim 25, wherein said displaying step displays a reduced image of the moving image file on said display device if the reduced image of the still picture file is selected.

28. A reproducing method according to claim 25, wherein said detecting step detects whether there is the moving image file on the basis of a header of the still picture file.

25. A reproducing method comprising the steps of:

detecting whether there is a moving image file associated with a still picture file; and

displaying a reduced image of the still picture file and information indicating presence of the moving image file on a display device if there is the moving image file.
