Abstract

An image processing apparatus according to the present invention includes a playback unit for playing back image data and a plurality of pieces of playlist data from a recording medium, each of the plurality of pieces of playlist data representing a playback procedure of the image data; and a playlist processing unit for generating new playlist data in accordance with the plurality of pieces of playlist data recorded on the recording medium.

Claims

1. An image processing apparatus comprising:

a playback unit configured to play back image data and a plurality of pieces of playlists from a recording medium, each of the plurality of pieces of playlists representing a playback order of the image data;

a changing unit configured to change the playback order of the plurality of pieces of playlists; and

a playlist processing unit configured to generate a combined playlist representing the playback order of the plurality of image data each designated in the plurality of pieces of playlists in accordance with the playback order of the plurality of pieces of playlists changed by the changing unit,

wherein the combined playlist represents the playback order of the plurality of image data so as to play back the plurality of image data each designated in the plurality of pieces of playlists in accordance with the playback order of the plurality of pieces of playlists changed by the changing unit,

wherein the combined playlist represents the playback order of the plurality of image data so as to play back the plurality of image data each designated in the plurality of pieces of playlists in the orders each designated in the plurality of pieces of playlists; and

wherein the playlist processing unit determines the playback order of the plurality of image data represented by the combined playlists such that duplicate image data from among the plurality of image data each designated in the plurality of pieces of playlists is inhibited from being played back in a duplicate fashion.

2. The image processing apparatus according to claim 1, further comprising a setting unit configured to set a condition, wherein

the changing unit changes the playback order of the plurality of pieces of playlists in accordance with the condition set by the setting unit.

3. The image processing apparatus according to claim 2, wherein the changing unit changes the playback order of the plurality of pieces of playlists using additional information of the playlist.

4. The image processing apparatus according to claim 2, wherein the condition includes a generation date of the playlist.

5. The image processing apparatus according to claim 1, further comprising a selection unit configured to select a plurality of pieces of playlists from the plurality of pieces of playlists recorded on the recording medium, wherein the changing unit changes the playback order of the plurality of pieces of playlists selected by the selection unit, and wherein the playlist processing unit generates the combined playlist representing the playback order of the plurality of image data each designated in the plurality of pieces of playlists selected by the selection unit.

6. The image processing apparatus according to claim 1, further comprising a recording unit configured to record the combined playlist generated by the playlist processing unit on the recording medium.

7. The image processing apparatus according to claim 6, further comprising:

a playlist selection unit configured to select one of the plurality of playlists including the combined playlist recorded on the recording medium; and

a control unit configured to control the playback unit to play back the image data from the recording medium in accordance with the playback order represented in the playlist selected by the playlist selection unit.

8. An image processing method comprising:

playing back image data and a plurality of pieces of playlists from a recording medium, each of the plurality of pieces of playlists representing a playback order of the image data;

changing the playback order of the plurality of pieces of playlists; and

generating a combined playlist representing the playback order of the plurality of image data each designated in the plurality of pieces of playlists by combining the plurality of pieces of playlists in accordance with the playback order of the plurality of pieces of playlists changed,

wherein the combined playlist represents the playback order of the plurality of image data so as to play back the plurality of image data each designated in the plurality of pieces of playlists in accordance with the playback order of the plurality of pieces of playlists changed, and

wherein the combined playlist represents the playback order of the plurality of image data so as to play back the plurality of image data each designated in the plurality of pieces of playlists in the orders each designated in the plurality of pieces of playlists,

wherein the playback order of the plurality of image data represented by the combined playlists is determined such that duplicate image data from among the plurality of image data each designated in the plurality of pieces of playlists is inhibited from being played back in a duplicate fashion.
