Description

  The present invention relates to a content processing apparatus, a content display method, and a program.

In recent years, a system for transferring music content to a DAP (Digital Audio Player) using a transfer tool (for example, WMP (Windows Media (registered trademark) Player), iTunes) and viewing the music content captured in the DAP is known. ing. A user uses a PC to rip from a medium on hand (for example, a CD) or download through an external line to store music content as a digital signal. The stored music content is stored in a recording medium (for example, NAND flash ROM or HDD) in the DAP through a transfer tool or a drag and drop operation.
The music content stored in the DAP has various detailed information such as artist name, album name, track name (song name), genre name, and age. The user selects and reproduces desired music content using a list of detailed information displayed on the display unit provided in the DAP. The display unit includes a display such as a liquid crystal or an organic EL, and the user recognizes text information indicating detailed information displayed on the display.

  In addition to the audio files that make up the music content described above, various files such as images, videos, and texts are supported as the forms of files that can be played back in recent DAPs. The capacity of recorded recording media is increasing. Further, as the capacity of recording media increases, not only stores reproducible files, but also uses the DAP body as a storage device and stores unreproducible files. As a method for deleting unnecessary or unreproducible files, a method in which the user himself / herself finds the corresponding file or folder from a large-capacity recording medium, confirms the contents, and then manually deletes the file or folder.

For example, Patent Document 1 discloses a technique that allows a series of music groups (album units and artist units) to be distinguished from other music groups when only a list of track names is displayed on the display screen. Is disclosed. As a result, even when the user has only the minimum necessary information as described above, the user can recognize the necessity of the file and can delete the unnecessary file.

Track 003 is displayed with a font clarity of 80%, and the non-reproduction period is 31 to 90 days. Track007 is displayed with a font clarity of 60%, indicating that the non-reproduction period is 91 to 180 days. Note that Track 006 displayed between Track 005 and Track 007 has been erased for each audio file because the non-reproduction period has exceeded 360 days.
Thus, in the first embodiment, the non-reproduction period can be determined based on the clarity of the font, and when the non-reproduction period exceeds a predetermined period (360 days), the corresponding audio file is automatically deleted. The user can intuitively grasp the non-playback period, and can save the trouble of managing an audio file that has not been played back for a long time.

(Second Embodiment)
Next, in the second embodiment, when the non-playback period exceeds 360 days, the track name is not visible while the audio file remains, instead of deleting the track name for each audio file as in the first embodiment. A method for setting the state will be described with reference to FIG.
As shown in FIG. 7A, Track002 has a non-reproduction period of more than 360 days, and is in a non-display state (invisible state). Here, when the user operates a menu screen (not shown) by operating the operation unit 2 and selects “hidden list” from the menu, as shown in FIG. A list of songs set to is displayed. A flag (* mark in the figure) is given to the music selected by the user in the non-display list. For the music to which the flag is assigned, for example, a selection file process as shown in FIG. 7C can be performed by the user's menu operation. Specifically, the music can be deleted, or the track name of the music can be displayed again with a font clarity of 100%.

As described above, in the second embodiment, a method of making the track name invisible while keeping the audio file is employed. Here, a method of automatically erasing a corresponding audio file when a predetermined period has elapsed after making the track name invisible will be described with reference to FIG.
Since FIG. 8A is the same as FIG. 7A, the description is omitted. In FIG. 8B, after a predetermined period (for example, 30 days) has passed since the state of FIG. 8A (invisible state), the invisible music (Track 002) is automatically deleted. The situation is shown. Note that the user can arbitrarily set the predetermined period.

In addition, when the track name is made invisible as in the second embodiment, when the invisible music is selected by the user, the music is played and the track name of the music is displayed again. A method for this will be described with reference to FIG.
FIG. 9A is exactly the same as FIG. 7A and FIG. FIG. 9B shows a state in which the music (Track002) that has been made invisible by the user is selected from the state of FIG. 9A (invisible state). The track name of the music piece selected and reproduced in FIG. 9B is automatically redisplayed with a font clarity of 100%, as shown in FIG. 9C, for example.

  As mentioned above, although concretely demonstrated based on embodiment which concerns on this invention, this invention is not limited to the said embodiment, It can change in the range which does not deviate from the summary.

For example, in the above embodiment, the track name is displayed with the clarity of the font defined in the table diagram shown in FIG. 5, but this is not restrictive.
FIG. 10 is a diagram showing an example of a screen for setting a non-reproduction period associated with the clarity of the font.
As shown in FIG. 10, the user can arbitrarily set the non-reproduction period associated with the clarity of the font. The top row is associated with a font clarity of 80%, and in the same figure, the non-reproduction period 31 to 90 days is associated. The middle row is associated with a font clarity of 60%, and in the same figure, the non-reproduction period 91-180 days is associated. The bottom row is associated with a font clarity of 40%, and in the same figure, non-reproduction periods 181 to 360 days are associated.
Note that the double frame in the column “91” in the middle row in the figure indicates that the column has been selected by the user. For example, the number of days can be changed when the user operates the up / down key in a state where the frame of “91” having a font clarity of 60% is selected. When the number of days is changed by the user, the “90” field with the font clarity of 80% is also changed in conjunction.
