  By the way, as described above, the navigation device 1 has a route guidance function, and during route guidance, the position of the host vehicle and the route on which the host vehicle is to travel are displayed on the map displayed on the display unit 12. Become. In this case, when displaying the music information on the display unit 12, it is required to display the music information desired by the user while preventing the map, the position of the host vehicle, the route to be traveled, etc. from being obstructed as much as possible. . In view of this, the navigation device 1 according to the present embodiment performs the following operations when displaying music information on the display unit 12.

  FIG. 3 is a flowchart showing the operation when the navigation device 1 displays the music information on the display unit 12, particularly the operation of the navigation device 1 when the music is changed during reproduction. For convenience of explanation, it is assumed that the music recorded on the music CD is played by the media device 14 at the start of the flowchart. When the operation shown in the flowchart of FIG. 3 is executed, the control unit 10 functions as a display control unit, a pre-change music storage unit, a post-change music storage unit, and a change item specifying unit.

During the reproduction of the music, the control unit 10 monitors whether or not the music being reproduced has changed (step SA1). Here, the change of the music is, for example, that the playback target moves to the next music according to the order of the music recorded on the music CD, or the user operates the operation unit 13 to intentionally change the playback target music. This means that the music being played is changed to a different music. In the following description, for the sake of clarification, the change in the reproduction of the music is particularly referred to as “reproduction change”.
When the reproduction of music is changed (step SA1: YES), the control unit 10 executes a change item specifying process (step SA2). Here, the change item specifying process will be described in detail with reference to FIG.

  FIG. 4 is a flowchart showing the operation of the navigation device 1 in the change item specifying process. The change item identification process is a song that has been changed from the song related item of the song information before the playback change among the song related items of the song information of the song after the playback change when the playback of the song is changed This is a process of specifying related items (hereinafter referred to as “change items”). For convenience of explanation, at the start of the flowchart of FIG. 4, the music related items of the music information of the music before the reproduction change are stored in each field of the music information table 23 before the change by the process of step SB3 described later. It is assumed that the indicated data has already been stored.

  In the change item specifying process, first, the control unit 10 refers to the TOC information database 20 stored in the HDD 16 on the basis of the signal indicating the TOC information of the music after the playback change input from the media device 14, and changes the playback. Data indicating the singer name item, album name item, and song name item of the later music is acquired, and these data are stored in each field of the changed music information table 24 (step SB1). Next, the control unit 10 compares the data stored in each field of the pre-change music information table 23 with the data stored in each field of the post-change music information table 24, and the data contents are different. The change item mentioned above is specified by specifying the field of the post-music information table 24. That is, in the example shown in FIG. 2, the data stored in the singer name fields 23A and 24A (both singer name items are “XXX”) and the data stored in the album name fields 23B and 24B ( Although the album name items are the same for both, the data stored in the song name fields 23C and 24C (the song name item in the pre-change music information table 23 is “ΔΔΔ”, the music information after the change) The table 24 specifies the song name field 24C as a field in which the contents of the stored data are different because the song name items are different in “□□□”). And the control part 10 specifies the music related item which concerns on the data stored in the music title field 24C of the music information table 24 after a change as a change item.

Further, after specifying the change item, the control unit 10 stores data indicating the specified change item in the corresponding field of the change item table 25. Here, the data indicating the change items stored in the change item table 25 is referred to when music information is displayed on the display unit 12 later.
After identifying the change item, the control unit 10 updates the pre-change music information table 23 with the contents of the post-change music information table 24 (step SB3). As a result, when the reproduction of the music is changed next time, the data stored in the pre-change music information table 23 can be used as data indicating the music information of the music before the reproduction change.
Now, referring back to FIG. 3, after executing the change item specifying process, the control unit 10 executes the change item display process (step SA3). Here, the change item display processing will be described in detail with reference to FIG.

FIG. 5 is a flowchart showing the operation of the navigation device 1 in the change item display process. The change item display process is a process for displaying the change item specified in the change item specifying process on the display unit 12.
In the change item display process, first, the control unit 10 determines whether or not a special display is displayed on the display unit 12 (step SC1). Here, the special display will be described. In the navigation device 1 according to the present embodiment, when the vehicle approaches a certain intersection at the time of route guidance, a 3D screen 30 (see FIG. 7) near the intersection is displayed on the display unit. The 3D screen 30 corresponds to the special display, although it has a function that allows the user to easily grasp the route by displaying it at the center of 12. The 3D screen 30 near the intersection is displayed, for example, when the vehicle approaches the next guidance route intersection during route guidance. In addition, the present embodiment has a function of pop-up displaying traffic information valuable to the user such as traffic jams and accidents. The traffic information displayed at this time corresponds to special display. That is, the special display is a display having a higher display priority than the map and the music information, and is a generic name for what is displayed on the display unit 12 according to a predetermined condition.
The traffic information includes, for example, VICS information obtained by receiving an optical beacon, FM multiplex broadcast, or the like.

  When the special display is not displayed in step SC1 (step SC1: NO), the control unit 10 refers to the change item table 25 to acquire the change item to be displayed on the display unit 12, and displays this change item. The information is displayed at a predetermined position on the display unit 12 (step SC2). In this way, in step SC2, the control unit 10 displays only the changed items on the display unit 12 among the music related items of the music information of the music after the reproduction change. Hereinafter, the reason and display of only the changed items are displayed. A specific aspect in this case will be described.

First, the reason why the control unit 10 displays only the change items on the display unit 12 will be described.
When there is a music playback change, the music information that the user wants to know the most among the music information is the music related item of the music after the playback change that has changed from the music related item of the music before the playback change, that is, the change It is considered an item. This is because the user often knows the music-related items that have not changed before and after the playback change without referring to the display on the display unit 12, and it is unlikely that the user wants to know again. This is because the music related items that have changed before and after the playback change are considered to be newly confirmed or known. When applied to the example of the present embodiment, before and after the playback change, if there is no change in the singer name item and the album name item among the music related items and there is a change in the song name item, the singer name item and the album name that have not been changed The user often knows about the item, and it is unlikely that he wants to know it again, but it is thought that he wants to confirm a new song name item and want to know about it.
In view of this, in the present embodiment, when there is a reproduction change, the control unit 10 displays only the change item that is the music information that the user wants to know most on the display unit 12. Thereby, useful information is provided to the user and the convenience of the user is improved.

  And in this embodiment, the improvement of the visibility of the display part 12 is also aimed at by displaying only a change item on the display part 12. FIG. That is, when there are many music-related items to be displayed on the display unit 12, for example, when all of the singer name item, album name item, and song name item are displayed on the display unit 12, the music information displayed on the display unit 12 Increases, and the portion of the map that is hidden by the naturally displayed music information increases, and the visibility of the display unit 12 is hindered. However, in this embodiment, since only the change item which is the music information that the user wants to know most is displayed on the display unit 12, the music information displayed on the display unit 12 can be small and displayed on the display unit 12. The visibility of the map can be improved.

Next, a specific display mode when the change item is displayed in step SC2 will be described with reference to FIG.
6A and 6B are diagrams showing the state of the display unit 12 when the reproduction of the music is changed. FIG. 6A shows the state of the display unit 12 before the reproduction of the music is changed. FIG. The state of the display part 12 after a reproduction change is shown. In FIG. 6, reference numeral 33 is used for the music information.
As shown in FIG. 6B, when the change item 33 is displayed on the display unit 12 when the reproduction of music is changed, the control unit 10 displays the own vehicle mark 31 indicating the position of the own vehicle or the own vehicle. The change item 33 is displayed in a state where the route 32 (portion drawn by a thick line in FIG. 6), the direction display 17 and the like are avoided. For this reason, when the user recognizes the route 32 on which the host vehicle should travel, the route 32 can be easily recognized without the music information getting in the way. In particular, in the present embodiment, only a small amount of the change item 33 of the music information is displayed on the display unit 12, so that the vehicle mark 31, the route 32, the direction display 17 and the like described above can be easily avoided and displayed. Can do.
Furthermore, in this embodiment, when the change item 33 is displayed on the display unit 12, the display of the map around the change item 33 is not completely erased, but the brightness of the pixels around the periphery 34 is reduced. Specifically, the luminance of the pixel of the character part displayed in the change item 33 is displayed as it is, and the luminance of the pixels around the change item 33 is reduced. Alternatively, the luminance of the pixel of the character portion displayed in the change item 33 is displayed as it is, and the periphery 34 of the change item 33 is displayed as the background image displayed on the display unit 12 with the pixels of the change item 33 and the periphery 34. Displayed by pixels obtained by dividing the sum of the pixels. For this reason, the map in the location where the change item 33 was displayed can also be visually recognized, and the convenience of a user is improved.

Now, returning to FIG. 5 above, after displaying the change item at a predetermined position of the display unit 12 in step SC2, the control unit 10 starts measuring the predetermined period S (step SC3), and the predetermined period S has elapsed. It is monitored whether or not (step SC4), and when the predetermined period S has elapsed (step SC4: YES), the display of the change item on the display unit 12 is stopped (step SC5). Thus, in the present embodiment, when there is a change in the reproduction of music, the change item is displayed on the display unit 12 only for a predetermined period S, and the display is stopped after the predetermined period S has elapsed. This is because once the change item is displayed on the display unit 12 and the user recognizes the contents of the change item, the necessity of displaying the change item on the display unit 12 is reduced. This is to improve the visibility of the map by stopping the display on the map. In particular, in the present embodiment, since only a small amount of information, that is, a change item is displayed on the display unit 12, the user can recognize and understand the content of the change item in a short period of time.
As the predetermined period S, a period that is considered necessary for the user to recognize the change item is set, and for example, 10 seconds is set.

On the other hand, when the special display is displayed on the display unit 12 in step SC1 (step SC1: YES), the control unit 10 displays the special display on the display unit 12, and the special display, the vehicle mark. 31, it is determined whether or not the change item can be displayed on the display unit 12 with a predetermined size while avoiding the path 32 and the direction display 17 (step SC6).
When the change item can be displayed on the display unit 12 with a predetermined size (step SC6: YES), the control unit 10 refers to the change item table 25, acquires the change item, and displays the special display, the own vehicle mark 31, the route. 32 and the change item are displayed on the display unit 12 with a predetermined size in a state where the direction display 17 is avoided (step SC7).
Here, the operation of step SC7 will be described with reference to FIG.

FIG. 7 is a diagram illustrating a state of the display unit 12 when the reproduction of the music is changed, (A) illustrates a state of the display unit 12 before the reproduction of the music is changed, and (B) illustrates the state of the music. The state of the display part 12 after a reproduction change is shown. In FIG. 7, reference numeral 33 is used for the music information.
As shown in FIG. 7B, the control unit 10 displays the change item 33 on the display unit 12 while avoiding the 3D screen 30 (special display), the own vehicle mark 31, the route 32, and the direction display 17. To do. Thereby, when the user recognizes the route 32 on which the host vehicle should travel, the route 32 can be easily recognized without the music information getting in the way. In particular, the display of the 3D screen 30 (special display) having a higher priority than the map and music information is reliably maintained, and the convenience for the user can be improved. Furthermore, in this embodiment, since only a small amount of information of the change items 33 among the music information is displayed on the display unit 12, the 3D screen 30, the own vehicle mark 31, the route 32, the direction display 17, and the like described above can be easily performed. It can be avoided and displayed. Further, when the change item 33 is displayed on the display unit 12, the display of the map around the change item 33 is not completely erased, but the brightness of the pixels around the periphery 34 is reduced. Specifically, the luminance of the pixel of the character part displayed in the change item 33 is displayed as it is, and the luminance of the pixels around the change item 33 is reduced. Alternatively, the luminance of the pixel of the character portion displayed in the change item 33 is displayed as it is, and the periphery 34 of the change item 33 is displayed as the background image displayed on the display unit 12 with the pixels of the change item 33 and the periphery 34. Displayed by pixels obtained by dividing the sum of the pixels. For this reason, the map in the location where the change item 33 was displayed can also be visually recognized, and the convenience of a user is improved.

On the other hand, when the change item cannot be displayed on the display unit 12 with a predetermined size (step SC6: NO), the control unit 10 acquires the change item with reference to the change item table 25, and displays the change item as a special display. The size of the change item to be displayed is reduced and displayed on the display unit 12 so that the change item can be displayed on the display unit 12 while avoiding the route and direction display 17 (step SC8). Thereby, the user can refer to the entire change item in a state where the route can be easily recognized.
In step SC7 or step SC8, after displaying the change item on the display unit 12, the control unit 10 starts measuring the predetermined period S (step SC3) and monitors whether or not the predetermined period S has passed ( Step SC4) When the predetermined period S has elapsed (step SC4: YES), the display of the change item on the display unit 12 is stopped (step SC5).

  Now, returning to FIG. 3 above, after the change item is displayed on the display unit 12 by the change item display process, the control unit 10 returns the process to step SA1, and again determines whether or not the reproduction of the music has been changed. In other words, the change item specifying process in step SA2 and the change item display process in step SA3 are performed at any time when the reproduction change of the music occurs.

  In the above-described embodiment, the present invention has been described by taking as an example the case where the reproduction of music is changed in a state where the reproduction of music by the media apparatus 14 has already been performed. For example, the following operation is performed when there is no music before the playback change, such as when playing a CD or when playback of the music by the media device 14 is stopped. That is, when the music CD is extracted from the media device 14 or the reproduction of the music CD is stopped by the user, the control unit 10 once clears the contents of each field of the pre-change music information table 23. Next, when a music piece of a new music CD is played by the media device 14 or when the user instructs to play the music piece again, the control unit 10 performs the operation based on the music information of the music piece to be played back. All the music related items of the music information of the music are displayed on the display unit 12. Thereafter, according to the above-described operation, only the change items are displayed at the timing when the reproduction change of the music occurs, and the visibility of the display unit 12 is improved. Here, in the above description, an example of the timing for clearing the contents of each field of the pre-change music information table 23 has been described. .
