Description

  The present invention relates to an in-vehicle electronic system having a navigation function and an audio function, and more particularly to a method for displaying audio information in a navigation screen.

  As a vehicle-mounted electronic device, a navigation device that searches for a route to a destination or displays a road map around the vehicle position, an audio device that reproduces audio data, and a visual device that reproduces video data are used. As the data to be reproduced becomes multimedia, these in-vehicle electronic devices are required to be used as an integrated system rather than being used alone. In this specification, a system in which a navigation device, an audio device, and a visual device are combined is referred to as an AVN (Audio Visual Navigation) system (registered trademark) for convenience.

  The AVN system integrates each independent function, and shares various display information provided by each function in one display. For example, when the navigation function is executed, road map information or the like is displayed on the display, and when the audio function is executed, information on the audio data to be reproduced is displayed on the display. In addition, various information for providing a user interface is displayed on the display.

  Japanese Patent Laid-Open No. 2004-133867 describes a content providing apparatus that provides content such as music data after adjusting the transparency of characters indicating content information (track number, reproduction time, etc. of music data) and displaying the characters for a certain period of time. A technique for automatically erasing is disclosed. Specifically, when the content is switched, the transparency of the character indicating the content information is set to 0% and the content information is displayed for a certain period of time. After that, the transparency is set to 100% and the character is deleted from the screen.

  As an exemplary embodiment of the present invention, an in-vehicle AVN system will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram illustrating an outline of an in-vehicle electronic system according to the present embodiment. The AVN system 10 includes an antenna 12 that receives a television broadcast, a radio broadcast, and the like, a display 14 that is shared in the system, a speaker 16, and a user interface 18 that constitutes an interface with the user. The AVN system 10 includes a navigation function, an audio function, and a video function, and controls these functions.

  FIG. 2 is a block diagram showing a detailed configuration of the AVN system shown in FIG. The AVN system 10 includes a navigation function unit 20 having a function of guiding a route to a destination, an audio function unit 30 having a function of reproducing audio data, and a video function unit 40 for displaying video data on a display. A receiving unit 50 for receiving a television broadcast signal or a radio broadcast signal from the antenna 12, an external interface (external I / F) 60 for connecting an external portable medium or the like, an input unit for inputting a user instruction by a touch panel or key input 70, a storage device 80 for storing programs and various data necessary for executing each function, an audio output unit 90 for supplying audio signals to speakers, a display control unit 100 for supplying image data to be displayed on the display, Program memory 110, data memory 120, control unit for controlling each unit Configured to include a 30.

  The navigation function unit 20 calculates a vehicle position using a GPS satellite or a self-contained navigation sensor, reads road map data around the vehicle position from the storage device 80, and displays this on the display together with the vehicle position mark. To do. Further, the route from the vehicle position to the set destination is searched, the optimum guidance route is displayed on the road map, and the route to the destination is guided.

  The audio function unit 30 reproduces CDs, DVDs, semiconductor memories, portable media devices and other storage media, stored audio data, and audio data included in radio broadcasts and television broadcasts.

  The video function unit 40 reproduces video data recorded on a DVD, a semiconductor memory, a portable media device, and other storage media, and video data included in a television broadcast.

  The program memory 110 stores a program itself or a program loaded from the storage device 80. The program includes a navigation program 112 necessary for executing the navigation function, an audio reproduction program 114 necessary for reproducing audio data, and a video data reproduction program 116 necessary for reproducing video data. Further, in this embodiment, as will be described later, a pop-up display program 116 for displaying a pop-up image including audio information related to audio data when a navigation function is executed, and a music for searching for a music from the pop-up image A search program 118 and the like are stored.

  The data memory 120 stores data necessary for program execution. For example, format data 126 when storing road map data 122 around the vehicle position when executing the navigation function, storing audio data reproduced when executing the audio function, or popping up the audio information described above, Pop-up image data 128 necessary for the pop-up image is stored.

  When the navigation function is executed, the AVN system of the present embodiment displays a navigation image necessary for navigation on the display. When the audio function is executed while the navigation function is being executed, the AVN system is reproduced on the navigation screen. A pop-up image of audio information related to the audio data can be displayed. For example, as shown in FIG. 10A, when audio data is reproduced while the road map image 300 is displayed on the display, a pop-up image 310 of audio information related to the audio data being reproduced is displayed on the road map image 300. Is displayed.

  FIG. 3 is a functional block diagram of the pop-up display program 116 of this embodiment. The pop-up display program 116 determines the timing for displaying the pop-up image and detects the target music, the display start / music detection unit 201, the attribute data acquisition unit 202 for acquiring the attribute data of the music being played, the pop-up image A pop-up creation unit 203 to be created, a priority comparison unit 204 that compares the priority of the navigation image and the pop-up image, and a display mode determination unit 205 that determines the display position and display time of the pop-up image are provided.

  Next, the operation of the display start / music detection unit will be described. FIG. 4A shows an example in which the display of the pop-up image is started when the display start / music detection unit detects a blank (cut) in the audio data. For example, when a reproduction list L arranged in the order of reproducing music data is created, a blank B that is a blank portion of several seconds is provided before and after each music data. The display start / music detection unit 201 sequentially detects each blank of the music data, and detects music data immediately after the blank. For example, when the display start / music detection unit 201 detects the blank B1 set before the music # 01, a pop-up image including the attribute data of the music # 01 is displayed, and then set before the music # 02. When the blank B2 is detected, a pop-up image describing the attribute data of the music # 02 is displayed.

  FIG. 4B shows an example in which the display start / music detection unit starts displaying a pop-up image at regular intervals. The display start / music detection unit 201 detects music data corresponding to the start points in response to the start points P1, P2,. When the start point coincides with the blank, the music data immediately after the blank is detected. If the start point is on the music data being reproduced, the music data is detected. For example, at the first start point P1, the display start / music detection unit 201 detects the music # 01 immediately after the blank B1, thereby displaying a pop-up image including the attribute data of the music # 01. Next, at the second start point P2 at which a predetermined time t has elapsed from the first start point P1, the music piece # 01 being reproduced is detected, and a pop-up image including this attribute data is displayed. The display start / music detection unit 201 may use any of the methods shown in FIGS. 4A and 4B or a combination thereof.

  The attribute data acquisition unit 202 acquires the attribute data from the corresponding music data in response to the music being detected by the display start / music detection unit 201. FIG. 5 is a diagram illustrating a configuration example of music data. The music data 124 includes body data 140 that is the music itself, and attribute data 150 that characterizes the music data. The attribute data 150 includes, for example, genre data 151, artist data 152, album data 153, title data 154, and the like. The attribute data acquisition unit 202 sends the attribute data 150 acquired from the music data 124 to the pop-up creation unit 203.

  The pop-up creation unit 203 reads the format data 126 from the storage device 80, writes the attribute data 150 sent from the attribute data acquisition unit 202 into the blank area, and creates the pop-up image data 128. The color tone of the pop-up image is preferably translucent so that the background navigation image can be seen through. Further, the color of the pop-up image may be changed as the color of the navigation image changes according to the time zone of morning and daytime and the topography such as the mountainous area and the coastline. For example, when the navigation image becomes dark blue at night, the pop-up image changes to a contrasting color such as red or white.

    FIG. 6A is an example of a pop-up image format 126A in which all attribute data is written in one pop-up image, and FIG. 6B is a divided pop-up that displays the pop-up image area divided by attribute data. It is an example of the format 126B of an image. Although there is no great difference between the two when the attribute data is checked, as described in the third embodiment, when the pop-up image is used as the switching function image, the latter simplifies the music search procedure.

  The priority comparison unit 204 compares priorities of various navigation images and pop-up images, and determines whether or not to display the pop-up images. As the navigation image, for example, a wide-area road map and a narrow-area road map image, an intersection guidance image, an input image, and the like are prepared, and guidance according to road conditions can be performed. Displaying pop-up images at all times sometimes obstructs important information in the navigation image. Accordingly, priorities are set in advance for various navigation images, the priority of display of intersection guidance or the like that hinders traveling is increased, and the priority of navigation images that do not interfere with traveling is decreased.

FIG. 7 is a table summarizing the priorities of various navigation images. For example, a priority of “Advanced” means that the navigation image has a higher priority than the pop-up image, and “Medium” means that both images have the same priority, which can be set or selected by the user. “Low” means that the navigation image has a lower priority than the pop-up image. For example, the guidance route guidance for a wide area map (with a scale of 1 / 25,000 or higher) has a lower priority than the pop-up image. Has higher priority than images. Camera images, interchange (IC) guidance, toll booth guidance, accident frequent spot guidance, railroad crossing guidance, and VICS information guidance images have the same priority as pop-up images, and by default these navigation images are set to have priority. However, the priority can be changed according to the user's selection.

  The display mode determination unit 205 determines the display position and display period of the pop-up image. It is desirable to display the pop-up image at a position where the own vehicle position, the nearest intersection, the intersection that changes the traveling direction, the guide route, and other icons are not blocked as much as possible.

  FIG. 8 is a diagram for explaining the display position of the pop-up image. The road map image 300 displays the first intersection K1 and the second intersection K2, and also displays the vehicle position mark M and the guidance route R together. FIG. 8A is an example in which the vehicle travels straight through the first intersection K1 and the second intersection K2, and in this case, display areas 301 and 302 that do not overlap with the vehicle position mark M, the guidance route R, and the intersections K1 and K2. Is selected as a candidate. In the display area, an area that does not overlap with other icon displays is selected as the final display position. FIG. 8B is an example of going straight at the first intersection K1 and turning right at the second intersection K2. In this case, the vehicle position mark M does not overlap with the intersections K1 and K2, and the guidance route R The display area 302 opposite to the traveling direction is selected as a candidate. FIG. 8C is an example in which the vehicle travels straight through the first intersection K1 and turns left at the second intersection K2. In this case, the vehicle does not overlap with the vehicle position mark M and the intersection K1, A display area 303 opposite to the traveling direction is selected as a candidate.

  The display mode determination unit 205 sets the display period of the pop-up image to 3 seconds as an initial setting, for example. The display time can be changed by the user, but is limited to a maximum of 5 seconds, for example, in order to prevent a driver's side-view driving.

  Next, a pop-up image display operation in the AVN system of the present embodiment will be described with reference to the flowchart of FIG. First, the navigation function unit 20 is executed (step S101), and a road map around the vehicle position is displayed on the display. Next, in parallel with the navigation function, the audio function unit 30 is executed to reproduce the music data (step S102). For example, a plurality of songs included in a medium such as a playlist or a CD are reproduced in a certain order or randomly.

  In response to the execution of the audio function, the pop-up display program 116 is activated. When the display start / music detection unit 201 detects a blank of a plurality of music such as a playlist or a CD (step S103), the attribute data acquisition unit 202 reads the attribute data of the music data following the blank (step S104). The read attribute data is provided to the pop-up creation unit 203, and the pop-up creation unit 203 writes the attribute data in the blank of the format data to create pop-up image data 128 (step S105).

  Next, the priority comparison unit 204 detects the priority set for the displayed navigation image (step S106) and compares it with the priority of the pop-up image (step S107). When the pop-up image has priority over the navigation image (step S108), the display mode determination unit 205 determines the display position and display period of the pop-up image (step S109), and in response to this, the display control unit 100 displays the navigation image. The pop-up image is synthesized with the image and displayed on the display (step S110). The display mode determination unit 205 measures the display time of the pop-up image, and when the determined period has elapsed (step S111), the display of the pop-up image by the display control unit 100 is stopped (step S112). In addition, when the display of the navigation image has priority over the pop-up image, the display of the pop-up image is skipped.

FIG. 10A shows a state where a pop-up image is displayed on the navigation image, and FIG. 10B shows a state where a pop-up image is not displayed.
When audio playback is performed during the execution of the navigation function, a pop-up image 310 is synthesized and displayed on the road map image 300 as shown in FIG. The pop-up image 310 is displayed in a semi-transparent state and at a position where there is no obstacle to the road map as much as possible. This pop-up image 310 displays the genre, artist, album, and title.

  When the pop-up image 310 is displayed for a certain period, it is deleted as shown in FIG. Next, the pop-up image is displayed when a predetermined time has elapsed or when switching to the reproduction of the next music.

  Next, a second embodiment of the present invention will be described. The second embodiment is characterized in that the pop-up image functions as a user interface, and when the user selects the displayed pop-up image, the audio playback function is automatically switched to the music search function.

  FIG. 11 is a functional block diagram of a pop-up display program according to the second embodiment. The second embodiment includes an input detection unit 206 and a function switching unit 207 in addition to the functional block diagram of the first embodiment. The input detection unit detects that the currently displayed pop-up image is pressed or selected by panel touch or key input. When the input detection unit 206 detects selection of the pop-up image, the function switching unit 207 switches the display on the display from the navigation screen to the music search screen.

  FIG. 12 is a flowchart showing operations from pop-up image display to music search according to the second embodiment. However, the method for displaying the pop-up image is the same as that in the first embodiment shown in FIG.

  First, a pop-up image is displayed on the navigation image (step S201). The pop-up image has a format as shown in FIG. The input detection unit 206 detects whether or not a pop-up image has been selected during display of the pop-up image (step S202). When the selection of the pop-up image is detected, the audio reproduction program 114 stops the reproduction of the music (step S203) and starts the music search program 118 (step S204).

  When the music search program 118 is activated, the function switching unit 207 instructs the display control unit 100 to switch the display screen, whereby the display on the display is switched from the navigation screen to the music search screen (step S205).

  The music search screen may be a screen for selecting music hierarchically from a plurality of attributes, or may be a search screen associated with the attribute data of the pop-up image. For example, if the genre of the song being played is lock, a search screen showing a list of songs with the lock attribute is displayed, or a search screen showing a list of songs of the artist being played is displayed. Or, a search screen for other albums and playlists is displayed. Thereby, a user's search operation becomes easy.

  When the music to be played is selected (step S206), the music search program 118 ends, and the audio playback program 114 starts playing the selected music (step S207). As the music is played back, the function switching unit 207 instructs the display control unit 100 to switch the display screen, and the display on the display is switched from the music search screen to the navigation screen (step S208). As in the first embodiment, the pop-up image is discontinuously displayed on the navigation image.

  FIG. 13A shows a display example of the music search screen 320. From the search screen 320, genre search, artist search, album search, and title search can be selected, and a desired music can be searched from there.

  For example, when a genre search is selected from the music search screen 320 shown in FIG. 13A, a genre search screen 330 is displayed as shown in FIG. 13B, where rock, pops, jazz, classic, etc. are written. Has been. Next, when the lock is selected from the genre search screen 330, a music list 340 showing the titles of the music belonging to the lock is displayed as shown in FIG. 13C, and the music to be reproduced is determined therefrom. In addition, when there are a large number of songs described in the song list, such as 100 songs or more, narrowing conditions such as artist names, album names, Japanese music, and Western music may be added.

  Next, a third embodiment of the present invention will be described. As a cause of the occurrence of accidents in recent years, “careless attention during audio operation” is ranked high, and a music search method with fewer operations is required. Therefore, the third embodiment discloses a music search method that requires fewer operations than the second embodiment.

  FIG. 14 is a flowchart for explaining operations from pop-up display to music search according to the third embodiment. As in the first embodiment, the pop-up image is combined with the navigation image and displayed (step S301). Here, the pop-up image has a format 126B shown in FIG. When the format 126B is used, the pop-up image can provide an input interface divided for each attribute data. FIG. 15 is a display example of a divided pop-up image 350 having an input interface for each attribute data. The divided pop-up image 350 includes a genre area 352, an artist area 354, an album area 356, and a title area 358.

  The input detection unit 206 detects whether or not the divided popup image 350 being displayed is pressed or selected (step S302). If selected, the input detection unit 206 further detects which area of the divided pop-up image is pressed or selected (step S303), and further identifies attribute data corresponding to the pressed area (step S303). S304). For example, if the genre area 352 is selected, the genre is identified as attribute data. Next, the reproduction of the music is stopped (step S305), and the music search operation is started (step S306). The music search program 118 displays a search screen based on the attribute data of the selected area. For example, if a genre area is selected, a genre search screen 330 as shown in FIG. 13B is displayed. The subsequent operation is the same as in the second embodiment.

  Next, a fourth embodiment of the present invention will be described. The music data reproduced by the audio function unit 30 is not limited to the data stored in the storage device 80 or the portable media device, and includes terrestrial digital television broadcasts and radio broadcasts received by the reception unit 50. Digital terrestrial television broadcasting provides electronic program guides (hereinafter referred to as EPG) in addition to providing images and audio data with higher image quality and higher sound than before. While the vehicle is running, it is not possible to project a TV image on the display, but audio output is possible.
