display control means for causing a display to display type information representing the display types of pictures and position information representing a position of a picture designated by picture-designation operating means operated in designating a picture to be displayed.

3. A data processing apparatus according to claim 1, wherein the display types represent display methods in which resolutions in displaying pictures or display rates in displaying pictures are different from one another.

4. A data processing apparatus according to claim 3, wherein

the variations are fineness information representing a degree of spatial change in a picture, and

the display-type determining means determines, when the fineness information of a picture indicates that a degree of spatial change is large, a high resolution/low display rate type having a high resolution or a low display rate as a display type for the picture.

5. A data processing apparatus according to claim 3, wherein

the variations are motion information representing degrees of temporal change in pictures, and

the display-type determining means determines, when the motion information of a picture indicates that a degree of temporal change is large, a low resolution/high display rate having a low resolution or a high display rate as a display type for the picture.

6. A data processing apparatus according to claim 3, wherein

the display types include a still image type that represents display in a still image, and

the display-type determining means determines the still image type, which represents display in a still image, as a display type for a picture having a small variation.

7. A data processing apparatus according to claim 1, wherein

the display-type determining means determines a display type on the basis of a comparison result obtained by comparing variations in the pictures and predetermined thresholds, and

the display control means causes the display to further display a graph representing the variations in the pictures in time series together with threshold information representing the thresholds.

8. A data processing apparatus according to claim 7, wherein

the threshold information is moved according to operation by a user, and

the display-type determining unit determines a display type again on the basis of a comparison result obtained by comparing the variations in the pictures and thresholds represented by the threshold information after the movement.

9. A data processing apparatus according to claim 8, wherein the display control means causes the display to display type information again when a display type is determined by the display-type determining means again.

10. A data processing apparatus according to claim 7, wherein

fineness information representing a degree of spatial change in a picture and motion information representing a degree of temporal change in a picture are stored in a file as variations in a unit of picture, and

the display control means causes the display to display a graph representing the fineness information in time series, a graph representing the motion information in time series, or both the graph representing the fineness information in time series and the graph representing the motion information in time series.

11. A data processing apparatus according to claim 10, further comprising selection operating means operated in selecting the graph representing the fineness information in time series, the graph representing the motion information in time series, or both the graph representing the fineness information in time series and the graph representing the motion information in time series to be displayed.

12. A data processing apparatus according to claim 1, wherein

the picture-designation operating means is a bar in which a dial is movable,

pictures are allocated in time series to subsections dividing a movable range in which the dial is movable, and

the display control means causes the display to display position information representing a position of a picture allocated to a subsection in which the dial is located.

13. A data processing apparatus according to claim 12, wherein

the display control means causes the display to further display allocation range information representing an allocation range that is a range of pictures in time series allocated to a front subsection to an end subsection in the movable range,

the allocation range information is moved according to operation by a user, and

a front picture to an end picture in the allocation range represented by the allocation range information are allocated to the front subsection to the end subsection in the movable range.

2. A data processing apparatus that processes image data of a moving image, the data processing apparatus comprising:
