FIG. 2 shows an example of the data structure of the audio data reproduction information. The audio reproduction information 104 can include a plurality of reproduction lists # 1, # 2,... #N as shown in FIG.

  One playlist defines the playback order of a playback group obtained by grouping a plurality of music pieces. In this embodiment, an album is used as a playback group in the following example. The album is, for example, a name or an identification mark given to one CD or DVD. In other words, if the album is different, the reproduced music is different. In addition to such an album, the reproduction group may be a collection of a plurality of songs arbitrarily grouped by the user, for example. In the example of FIG. 2, playlist # 2 defines the playback order of albums A, B, C,.

  Furthermore, one album includes album image data unique to the album and music data related to a plurality of music pieces included in the album. As the album image data, for example, a jacket photo previously given to a CD can be used. It is also possible to register other images in association with the album. The music data includes audio data, music title, music playback time, performer data, and the like.

  The playlist can be created based on albums and music stored in the storage device 120 as desired by the user. Or it can create based on the album and music memorize | stored in the medium connected to the external interface 110. FIG. Alternatively, if the user does not create a playlist, the playlist may be automatically created based on the artist name, alphabetical order, update date, and the like. The created reproduction list is stored in the storage device 120, and can be edited or deleted through the input unit 70 thereafter.

  FIG. 3 is a functional block diagram of the audio playback program shown in FIG. The audio playback program 94 includes a playlist creation unit 140 that creates the playlist shown in FIG. 2, a playlist storage unit 142 that stores the created playlist in the storage device 120, and playback that selects a playlist to be played back. A list selection unit 144, an audio screen generation unit 146 that generates an audio screen including album image data corresponding to an album in the playlist, and a layer of the generated audio screen is combined with a layer of the navigation screen to display the audio screen. It includes an audio screen display unit 148, a playlist editing unit 150 that edits a playlist in response to an input from the user, and a playback unit 152 that plays back music according to the playlist.

  Next, an audio screen display operation in the AVN system will be described with reference to the flowchart of FIG. The display of the audio screen here is performed when the navigation function unit 20 executes the navigation screen, that is, when road map information around the vehicle position is displayed on the display. First, a playlist as shown in FIG. 2 is created by the playlist creation unit 140 (step S200). When the playlist is created, the playlist storage unit 142 stores the created playlist in the storage device 120 (step S201).

  When the audio function unit 30 is executed in response to an instruction from the user, the playlist selection unit 144 selects any one of a plurality of playlists stored in the storage device 120 (step S202). This selection may be performed according to a user instruction, or may be automatically selected in response to an audio reproduction instruction, for example, the latest reproduction list.

  When the play list is selected, the audio screen generating unit 146 generates an audio screen including album image data corresponding to the album of the selected play list (step S203). FIG. 5 is a diagram illustrating a configuration example of an audio screen. As shown in the figure, the audio screen 200 is divided into a plurality of rectangular areas 210, 212, 214, 216, 218, and 220, and album image data corresponding to each area is assigned. In this example, the audio screen 200 is divided into six areas, and six album image data are displayed in each area.

An area 210 is a reproduction area, and an album corresponding to the album image data displayed in the reproduction area 210 is reproduced. Areas 212 to 220 correspond to the playback order of albums in the playlist. For example, the album image data displayed in the area 212 is an album to be reproduced next. When the reproduction of the album in the reproduction area 210 is finished, the album image data in the area 212 is scrolled to the reproduction area 210. In response to this, the album image data in the area 214 moves to the area 212, and similarly, the album image data displayed in the other areas 216 to 220 also moves. If the playlist includes more than six albums, the seventh album image data is displayed in the area 220. A broken line 230 is a display area of the audio screen, and the outside of the display area 230 is a blank 232. This blank 232 is displayed when the album image data or the audio screen is scrolled.

  Next, the audio screen display unit 148 synthesizes and displays the generated audio screen on the navigation screen (step S204). FIG. 6A shows a display example when the audio screen is combined with the navigation screen. As shown in the figure, the navigation screen 300 includes a vehicle position mark M and road map information 302 around the vehicle position. Here, the navigation screen 300 is displayed in a head-up state in which the traveling direction of the host vehicle always faces upward.

  As described above, the audio screen includes album image data corresponding to albums in the plurality of areas 210 to 220, and these album image data are displayed as background images of road map information. The playback area 210 of the audio screen 200 overlaps with the vehicle position mark M on the navigation screen. That is, the own vehicle position mark M indicates the album being reproduced. In the display example of FIG. 6A, album image data A, B, C, D, E, and F are displayed, and the album of the album image data E that overlaps with the vehicle position mark M is being reproduced. Is shown. The album to be reproduced next is an area 212 adjacent to the reproduction area 210, and this area 212 coincides with the traveling direction of the road where the vehicle position mark M is present. Note that the playback area 210 may be highlighted with a rectangular frame for easier understanding.

  The playback unit 150 plays back the music included in the album in the playback area 210 (step S205). The audio data of the reproduced music is output from the speaker via the audio control unit 50. When the playback time has elapsed by the playback unit 150, the remaining playback time of the album decreases. The audio screen generation unit 148 scrolls the audio screen as the playback time elapses, and displays the remaining playback time of the album.

  FIG. 6B is a scroll example of the audio screen. As shown in FIG. 5A, at the start of album reproduction, the display area 230 displays all album image data assigned to the areas 210 to 220. As the playback time elapses, the audio screen generation unit 148 moves the position of the display area 230 relatively toward the position 230a as shown in FIG. 5B, thereby scrolling the audio screen. By this scrolling, the position of the album image data with respect to the vehicle position mark M is changed, and this becomes a measure of the remaining reproduction time of the album. As shown in FIG. 6B, it is possible to confirm that the reproduction of the album E in the reproduction area 210 is almost finished and the reproduction of the next album B is immediate with the vehicle position mark M as an index. . If the vehicle is traveling, the road map information is scrolled according to the traveling.

  When the reproduction of the album E is completed, the album B enters the reproduction area 210 and the reproduction of the music included in the album B is started. Thus, when the reproduction of all albums included in the selected reproduction list is completed (step S207), reproduction of the next reproduction list can be started.

Next, various display modes of an audio screen and editing of a play list according to the present embodiment will be described.
(A) Display of Play List FIG. 6A shows a basic display pattern of album images in the play list. As described above, each album image data is divided and displayed as the background of the road map 302 on the navigation screen 300, and the reproduction area 210 is set at a position overlapping with the vehicle position mark M. The own vehicle position mark M indicates the progress of the album, and is a measure of the playback time of the album E. Further, the vehicle position mark M indicates that the album B in the traveling direction is the album to be reproduced next. FIG. 6B shows a state immediately before the album being played is approaching the final stage and is next changed to the album scheduled to be played. The audio screen scrolls with the playback time of the album E, and the album E is switched to the next album B. When album B is reproduced, similarly, album A to be reproduced next is displayed in the traveling direction of the own vehicle position mark M. The playback order of albums is determined in advance by a playback list.

  FIG. 7A shows another display example of album image data. In the display example shown in FIG. 6, the reproduction area 210 coincides with the own vehicle position mark M. However, the display example shown in FIG. 7A differs from the position of the own vehicle position mark M in the reproduction area 210a. A reproduction area 210a is set at a position on the right side in the figure adjacent to the vehicle position peripheral area 310, and the album image data being reproduced is displayed there. That is, the vehicle position peripheral area 310 displays normal road map information 302 that does not use album image data as a background image. In this case, in the audio screen, the area corresponding to the vehicle position peripheral area 310 is blank. In the area other than the vehicle position peripheral area 310, album image data is displayed as a background image.

  The album to be reproduced next is album image data B displayed in the traveling direction of the own vehicle position mark M, that is, in the own vehicle position peripheral area 310. By setting the reproduction area 210a and the vehicle position peripheral area 310 separately, there is an effect that the road map around the vehicle position week is somewhat easier to see. In the example of FIG. 7, the size of the own vehicle position peripheral area 310 is set to be approximately the same as the size of the other reproduction area 210 a, but the size of the own vehicle position peripheral area 310 is larger than the reproduction area 210 a. May be. Further, the vehicle position peripheral area 310 does not necessarily have to be rectangular.

  When the user selects album image data E being displayed in FIG. 7A with a mouse or a touch panel, a track list 320 included in the album is displayed as shown in FIG. 7B. The track list 320 includes the playback order of the music, the music title (title) of the music included in the album, the playback time, and the like. FIG. 7B shows that song # 1 of album E is being played back. Preferably, the currently playing music is highlighted and the playback time of the music is also displayed. Furthermore, when the user selects a desired music from the track list 320, the music can be reproduced. In this way, the user can confirm the playback state of the album only by selecting the album image. Also, when album image data other than the reproduction list 210a is selected, the track list of the album may be displayed.

(B) Editing a Playlist Next, a method for editing a playlist on the navigation screen will be described. FIG. 8A is a display example in which the reproduction area 210 shown in FIG. In this example, album E is being reproduced, and then album B is reproduced. When the user wants to change the playback order of albums, the user can move the album image data (for example, drag and drop operation). That is, the audio screen functions as a user interface for editing the playlist. When the album image data is moved, the playlist creation unit 140 updates the playlist according to the movement.

  FIG. 8B is a display example when the album image is moved. In the display example shown in FIG. 8A, when the user wants to listen to album A instead of the album E being reproduced, the user selects the album A by clicking or touching it. When the album A is selected, the album A and the album E being reproduced are switched, the album A moves to the reproduction area 210, and the reproduction of the album A is started. In this case, the playlist creation unit 140 changes the playback order of album A and album E. When album A is selected, the playback order of album A and album E is not necessarily exchanged, but the playback order of album A may be placed before album E. In this case, album E is moved to the next reproduction scheduled position of album A.

  FIG. 9 shows another example of editing the play list. Here, the display of road map information is omitted. FIG. 9A shows the basic display pattern shown in FIG. When the user wants to listen to the tenth music in album C during playback of album E, drag and drop or click album image C and move it to playback area 210 as shown in FIG. As a result, the images of album E and album C are interchanged, and reproduction is started from the top music of album C. Here, when the album image C is clicked, as shown in FIG. 9C, a track list 320 of the album C is displayed. By selecting the tenth music # 10 included therein, the music # 10 is displayed. Played. Since song # 10 is the last song, the audio screen is scrolled and the vehicle position mark M is displayed at the top of the album image C as shown in FIG. As a result, the user can visually determine that album C is about to end and album B will be played next.
