The time code 223 indicates the playback time of the music.

  The music image section 220 functions as an operation button. The image deletion button 224 functions as an operation button for deleting the music image portion 220 being displayed by the touch input. Further, the music image portion 220 other than the image deletion button 224 functions as an operation button for displaying a music detail display screen of the music being reproduced by the touch input.

  Next, the image display setting process executed by the navigation device 1 will be described with reference to FIGS. FIG. 3 shows the flow of the image display setting process. FIG. 4 shows a map screen 300 on which a translucent music image portion 330 is superimposed. FIGS. 5A to 5E show a semi-transparent image 420 that gradually increases on the map image 410.

  The image display setting process is a process of creating image display setting data related to image display during music reproduction and storing it in the HDD 40. Prior to the image display setting process, from an external recording medium such as a CD set in the disk drive 50, an external recording medium connected to the communication connection unit 60, or an external portable terminal, music data, its metadata, and any Assume that image data is input and stored in the metadata DB 41, the music DB 42, and the image DB 43 of the HDD 40, respectively. The metadata may be stored in the metadata DB 41 by accepting an operation input from the user by the operation unit 21, creating (editing) the metadata according to the operation input.

  In the navigation device 1, for example, an image display setting program appropriately read from the HDD 40 by the control unit 10 is triggered by the operation unit 21 receiving an operation input of an instruction to execute the image display setting process. Based on this, an image display setting process is executed.

  First, an image display setting screen is displayed on the display unit 22, and an operation input of setting information related to image display is received from the user by the operation unit 21 (step S1). Then, image display setting data is created from the setting information input in operation in step S1, and stored in the HDD 40 as the image display setting data 44 (step S2), and the image display setting process ends.

  The setting information in step S1 includes information that associates the music data (file) name of a certain music, the image data (file) name of the image to be displayed when the music is played back, and the music data (file) name.

  The setting information in step S1 includes display / non-display setting information for an image (music image portion). The display / non-display setting information may be setting information that is uniformly applied to all music pieces. Also, the display / non-display setting information may be setting information that allows image display / non-display settings in arbitrary units, such as music, albums, genres, or combinations thereof.

  Further, the setting information information in step S1 includes image display condition information. The image display condition information includes the display position and display size of the image on the map screen. For example, as shown in FIG. 2, on the map screen 200, the music image unit 220 sets the display position and display size of an image 221 that can recognize the image contents without disturbing the display of necessary information on the map image unit 210. It is preferred that

  The setting information in step S1 includes display timing and display time setting information as display condition information for an image (music image portion). For example, as shown in FIG. 2, on the map screen 200, the display timing is set to display an image 221 related to the music at the same time as the music playback start, and the displayed image is displayed after 5 seconds. 221 is set to be automatically deleted. However, it is not limited to these, and other display times are set, such as displaying an image after a predetermined time has elapsed since music playback, such as displaying the image until the end of the song. May be.

  Further, the setting information in step S1 includes display display information of the image as display condition information of the image (music image portion). For example, as shown in FIG. 2, in the map screen 200, the display expression information is set so that the music image portion 220 is superimposed on the map image portion 210 without being transparent.

  The display expression information may be setting information for displaying an image semi-transparently. As shown in FIG. 3, the semi-transparent display is a display expression displayed on the map screen 300 in a semi-transparent manner by the music image unit 330 on the map image 310 and the enlarged image 320 of a partial area thereof. is there. Since the music image portion 330 is translucent, the map image 310 and the enlarged image 320 can be visually confirmed through the music image portion 330. Further, the transparency may be arbitrarily set.

  Further, the display expression information may be dynamic expression setting information for performing display by dynamically changing an image. The dynamic expression is an expression that has some movement over time, for example, an animation expression (fade-in) in which an image is gradually enlarged, or an image blinks. The dynamic expression for gradually increasing the image is as shown in the flow of FIG. 5 (a) → FIG. 5 (b) → FIG. 5 (c) → FIG. 5 (d) → FIG. In the map screen, the music image portion 420 is displayed on the map image 410 so as to be enlarged gradually. Note that the images of the music image portions 330 and 420 are, for example, jacket photo images of a music album. The display expression information may include setting information for dynamic expression at the time of image erasure. The dynamic expression at the time of erasing the image is, for example, an animation expression (fade out) that gradually reduces the image.

  Next, with reference to FIG. 6 and FIG. 7, a music reproduction process executed by the navigation device 1 will be described. FIG. 6 shows the flow of the music reproduction process. FIG. 7A shows a touch input to the music image portion 220 of the map screen 200. FIG. 7B shows a music detail display screen 500 corresponding to the music image portion 220 of the map screen 200.

  The music reproduction process is a process of reading music data stored in the HDD 40 or the like and reproducing the music and displaying an image related to the music when the map screen is displayed on the display unit 22. The music playback target is stored in music data stored in the HDD 40 or the like, music data stored in an audio disk set in the disk drive 50, or an external recording medium or an external terminal device connected to the communication connection unit 60. Music data. However, when music data stored in an audio disk set in the disk drive 50 or music data stored in an external recording medium or external terminal device connected to the communication connection unit 60 is played back, Assume that the corresponding image display setting data is set and included in the image display setting data 44.

  In the navigation device 1, when the map screen is displayed on the display unit 22 at the time of navigation or otherwise, for example, the operation unit 21 triggers that the operation input of the music reproduction processing execution instruction from the user has been received. As a result, the music reproduction process is executed by the control unit 10 based on the music reproduction program appropriately read from the HDD 40.

  First, a music reproduction setting screen is displayed on the display unit 22, and an operation input of setting information related to music reproduction is received from the user by the operation unit 21, and is stored and set in the RAM of the control unit 10 as setting information ( Step S11). The setting information includes selection information of music to be played back, order information of music to be played back, and the like.

  Then, the image display setting data 44 is referred to, and it is determined whether or not the image display is set for the music to be reproduced next among the music to be reproduced set in step S11 and step S21 (step S12). . When image display is set for the music to be reproduced next (step S12; YES), the music data to be reproduced next is read from the music DB 42 or recorded externally via the disk drive 50 or the communication connection unit 60. By reading out from the medium or the external terminal device, outputting to the decoder unit 80, and outputting the sound from the speaker unit 90, the music reproduction is started using the music data. Further, the image display setting data 44 is referred to, image data corresponding to the music to be reproduced is read from the image DB 43, and an image (music image portion) of the image data is displayed on the map screen displayed on the display unit 22. Is superimposed and displayed (step S13). In step S13, the image display setting data 44 is referred to, and the image is superimposed and displayed according to the display timing and display expression of the image. In addition, the elapsed time by the time measuring unit 70 starts counting from the start of image display in step S13.

  Then, it is determined whether or not the elapsed time counted by the time measuring unit 70 has reached the display time of the image display setting data 44 from the start of image display in step S13 and the image display is ended (step S14). When image display is not set for the music to be reproduced next (step S12; NO), the music data to be reproduced next is read from the music DB 42, or the external recording medium via the disk drive 50 or the communication connection unit 60. Alternatively, it is read out from the external terminal device, output to the decoder unit 80, and output from the speaker unit 90 as sound, whereby the music reproduction is started using the music data (step S15), and the process proceeds to step S14. In steps S13 and S15, the reproduction can be started from the middle of the music according to the setting in step S11 or S26.

  When the image display is not finished (step S14; NO), it is determined whether or not some operation input from the user is accepted by the operation unit 21 (step S16). When the image display is ended (step S14; YES), the image related to the music is deleted from the map screen displayed on the display unit 22, the image display is ended (step S17), and the process proceeds to step S16. .

  If there is no operation input (step S16; NO), it is determined whether or not the music being played has ended (step S18). When the music being reproduced has not ended (step S18; NO), the process proceeds to step S14. When the music being played is finished (step S18; YES), all the music to be played set in step S11 is played, and it is determined whether or not the music playback is finished (step S19). When the reproduction of the music is not finished (step S19; NO), the process proceeds to step S12. When the reproduction of the music is finished (step S19; YES), the music reproduction process is finished.

  If there is an operation input (step S16; YES), it is determined whether or not the operation input content is a music change (step S20). For example, when the fast-forward button or the rewind button is pressed for a short time (touch input) while the music detail display screen, which will be described later, is displayed, it is determined that the operation input content is a music change (including music cueing). Is done. Further, when an instruction to change the source of music data is given, it is determined that the operation input content is music change. The music data source is a disk set in the HDD 40 or the disk drive 50 or selected by a user operation input, or an external recording medium or an external storage device connected to the communication connection unit 60. When the source is switched, in the reproduction of the first music (the music to be reproduced next) of the music data stored in the source after the switching, the image display is set to the music to be reproduced next in step S12. Shall be determined. That is, when the source is switched, an image related to the next music is displayed. If the operation input content is a music change (step S20; YES), the change of the music being played is set according to the operation input (step S21), and the process proceeds to step S12.

  If the operation input content is not a music change (step S20; NO), it is determined whether or not the operation input content is image display or image deletion (step S22). For example, when an image (music display image area) is not displayed, touch input corresponding to image display is performed, or when an image (music display image area) is being displayed, image deletion is supported. When touch input (touch input of an image deletion button) is made, it is determined that the operation input content is image display or image deletion. When the operation input content is image display or image erasure (step S22; YES), an image (music display image area) is superimposed on the map screen or displayed according to the operation content in the same manner as in step S13. (Music display image area) is deleted from the map screen (step S23), and the process proceeds to step S14.

  If the operation input content is not an image display or image deletion (step S22; NO), it is determined whether or not the operation input content is a music detail display screen display (step S24). In step S24, for example, as shown in FIG. 7A, it is determined whether or not the music image portion 220 excluding the image deletion button 224 is touch-input by the user on the map screen 200 being displayed on the display portion 22. The

  When the operation input content is a music detail display screen display (step S24; YES), a music detail display screen corresponding to the music being reproduced is displayed on the display unit 22 (step S25), and the process proceeds to step S14. In step S25, for example, the music image section 220 shown in FIG. 7A is touch-input by the user, and the music detail display screen 500 is displayed on the display section 22 as shown in FIG. 7B. The music detail display screen 500 includes an image 510, a song name 520, an artist name 530, an album name 540, a track number 550, a time code 560, a rewind button 570, a play / pause button 580, and fast forward. Button 590.

  An image 510 is an image related to the music being played back, and is the same image as the image 221. The song title 520 is the song title of the song being played. The artist name 530 is the artist name of the music being played. The album name 540 is the name of the album containing the music being played.
