  Car navigation systems are becoming more sophisticated and less expensive, and private cars equipped with car navigation systems are also increasing. As described in the patent literature, the car navigation system displays the route to be traveled by setting the destination on the display, stores the route traveled by the private vehicle, and displays the route. Can be displayed above.

  In recent years, digital cameras have become more sophisticated and less expensive. When traveling to a tourist spot with a private car, carry a digital camera. In many cases, snapshots are taken against these backgrounds. Ideally, the image data shot in this way is printed on photographic paper and stored as an album. However, since image data taken with a digital camera can be easily displayed on a home computer, it was also a reality that the image data was viewed on a computer after a trip and was not taken care of after that.

  From another point of view, when you travel to the direction you have visited once with a private car, you can enjoy the pleasure of traveling by making it possible to view snapshots of sightseeing spots you visited previously for each sightseeing point. Although it is doubled, as mentioned above, there is a tendency to print image data less, and even if you have made photos albums in sightseeing spots you have visited before, bring the albums to travel There are also annoying aspects and there is room for improvement.

  Therefore, it is conceivable to display image data on a map displayed on the display of the car navigation system as shown in Patent Documents 1 and 2, but the number of image data photographed at a sightseeing spot is relatively large. Considering the process of enlarging and displaying the image data by pasting the image data in the thumbnail format on the map and specifying the thumbnail format image data, the thumbnail format image data displayed on the display The number becomes too large, and there are many problems in terms of practicality.

  An object of the present invention is to configure a system that uses a navigation system and can rationally manage and display image data captured by a digital camera or the like.

A feature of the present invention is a navigation system comprising processing means for generating route data corresponding to a route traveled by a vehicle from position data acquired by a position acquisition means.
The processing means is grouped for each destination by the operator specifying the image data acquired by the image data acquisition means and stored in the first storage means, and the coordinates of the vehicle at each sampling timing Route data processing means for storing the data in the second storage means as the route data, and link data generating means for associating the destination and the route data with link data,
The processing means artificially selects the route data stored in the second storage means, and the destination existing on the route data is artificially or automatically designated, so that the link data is transmitted to the destination. In this case, there is provided an output means for extracting the group associated with each other and outputting the image data included in the group from the first storage means to the display .

With this configuration, for example, after the image data obtained by the digital camera is acquired by the image data acquisition means, the first storage means stores the image data grouped for each destination by the processing of the image storage processing means. By the processing of the route storage processing means, the second storage means stores the route on which the vehicle has traveled. After the image data and the route data are stored in this way, the link data generating means associates the destination stored in the first storage means and the route data stored in the second storage means by the link data. When this association is made, after the route data stored in the second storage means is artificially selected, the destination existing on the route data is artificially designated, Alternatively, for example, when the destination is automatically specified by the position acquisition unit, the output unit extracts a group associated with the destination by link data, and the image data included in the group is first stored. It can output to the display from the means. As a result, it can display the image data associated with the destination to the presence of a destination and a vehicle that is specified for to people to display. Further, even when a large number of image data is displayed, it is not necessary to display a large number of thumbnail format image data on the route data, and the display content of the display is not complicated.

According to the present invention, the processing means can arbitrarily generate route data on which the vehicle is not traveling and store it in the second storage means , and the route data is displayed on the route data in a state where the route data is displayed on the display. When a plurality of set destinations are specified artificially or automatically, image data included in a group associated with the destination is read from the first storage means and displayed on the display. May be.

  With this configuration, for example, route data that connects the destinations with the shortest distance although the vehicle is not traveling, route data that does not actually exist, and the like are arbitrarily generated, and image data for each destination on the route data is generated. By associating groups and, for example, simulating a situation in which a vehicle travels on route data, it is possible to display image data of a group corresponding to a destination where the vehicle is located on a display. That is, according to this configuration, route data such as a straight line or an arbitrarily set curve is generated, and the route data is displayed in a line or curve without displaying map data on the display. Simple display is realized by displaying image data for each destination on the data.

  The present invention includes a map data storage unit, and the processing unit extracts map data corresponding to the position data acquired by the position acquisition unit from the map data storage unit, and displays the map data on the map data. The processing mode may be set to display the route.

  With this configuration, the map data is displayed on the display, and the route data is displayed on the map data, thereby facilitating the understanding of the details of the route on which the vehicle has traveled. For example, even when displaying image data on the display, It is also possible to easily grasp the point where the image data is captured from the map data and the route data.

  According to the present invention, the image data acquisition unit acquires the image data stored in the digital drive or the semiconductor drive that acquires the image data from the semiconductor medium that stores the image data captured by the digital camera through the communication path. You may comprise with a terminal.

  This configuration makes it possible to acquire image data from semiconductor media used in digital cameras and to acquire image data via a cable connected to the digital camera, making it easy to capture image data taken with a digital camera. Can be obtained.

The present invention provides an image data storage function for grouping and storing a plurality of acquired image data for each destination, and a route data storage function for storing vehicle coordinate data at each sampling timing as route data indicating the route of the vehicle. A link data generation function for associating the destination and the route data with the image data grouped by an operator , and a destination existing on the artificially selected route data. Thus, the program may be configured such that a group associated with the destination by link data is extracted, and an output function for outputting image data included in the group to a display is executed by a computer.

With this configuration, the conventional navigation system is provided with image data acquisition means, and by improving the degree to which this program is installed, the image data storage function stores the image data, the route data storage function stores the route data, and the link data generating function associates the image data destination and grouping present on route data, the output function is shall be output image data associated with the link data for each destination on the display.

Means 14, link data generation means 15, output means 16, and storage processing means 17 are provided. Incidentally, in order to realize control in this processing device D, a control bus, an address bus, etc. are required in addition to a data bus. However, in order to avoid complication, the drawing shows a control bus, an address bus, or Does not show interfaces.

  The map matching unit 11 extracts the map data corresponding to the position data from the position acquisition unit P from the map database stored in the hard disk HD and displays the map data on the display C at a preset magnification. I do. The navigation means 12 extracts a route to a preset destination from the map data and displays it in a line on the map data displayed on the display C, and makes a right turn, a left turn, etc. at a point such as an intersection. Necessary operations are displayed on the display C, and necessary operations such as right turn and left turn are transmitted from the speaker to the operator in human language.

  The image storage processing means 13 performs processing for saving the image data acquired via the semiconductor drive 8, the disk drive 9, or the input / output terminal 5 in the hard disk HD (an example of the first storage means). Yes (image data storage function), when storing a plurality of image data in the hard disk HD, a screen enabling image data capture is displayed on the display C as shown in FIG. By performing the above operations, a plurality of image data are grouped for each destination and function to store them in an independent file (this function will be described later).

  The route storage processing means 14 performs processing for saving the route data R (see FIGS. 8 and 14) corresponding to the route on which the vehicle has traveled to the hard disk HD (an example of the second storage means) (route). Data storage function). The route data R is assumed to be a file having a structure in which data indicating the coordinates of the vehicle at each sampling timing is stored. However, the route data R includes a plurality of coordinates serving as a base point, a traveling direction and a traveling speed set for each coordinate. It may be a vector data structure. When the route data R stored by the route storage processing means 14 is displayed on the display C, the route indicated by the broken line in FIGS. 8 and 14 becomes the route data R, and a vehicle symbol V is shown on the route data R. On the route data R, a destination P (higher concept of a plurality of destinations P1, P2, P3.

  The link data generation means 15 associates image data for each destination P set on the route data R in a state where the link edit screen 33 shown in FIG. The process of saving in the format is performed (link data generation function), and the image data is displayed in the order of the saving. The output means 16 performs a process of displaying image data associated with the route data R on the display C as will be described later (output function).

  In addition, the storage processing unit 17 may select the selected route data R, a plurality of image data associated with the route data R, map data corresponding to the route data, and associated music data.

  The map matching means 11, navigation means 12, image storage processing means 13, route storage processing means 14, link data generation means 15 and output means 16 are assumed to be software (programs) developed on a semiconductor memory RAM. It is also possible to configure part or all of it with hardware such as logic.

  The route storage processing means 14 is set in a processing form so as to always save the route data R traveled by the vehicle. For example, in the case of relating a snapshot photograph taken with the digital camera Cam in a trip, etc. After finishing the trip and returning home, the processing menu 20 shown in FIG. 3 is displayed on the display C and the “acquire image data” button 21 is operated. In this processing menu 20, in addition to the “obtain image data” button 21, a “reproduction process (actual running mode)” button 22, a “reproduction process (replay mode)” button 23, and a “save to media” A button 24 and an “OK” button 25 are displayed.

  When the “acquire image data” button 21 is operated and the “OK” button 25 is operated, first, the association process shown in the flowchart of FIG. 9 is executed.

  In the association process, a plurality of image data acquired via the semiconductor drive 8 or the like is displayed on the image acquisition screen 27 shown in FIG. 4 (Step # 101). On the image acquisition screen 27, all of the acquired image data is displayed in the image display area 27A in the thumbnail format, and all the image data can be confirmed by operating the scroll bar 27B, and the displayed image data is selected. When the “delete” button 28 is operated, unnecessary image data is deleted from the acquired image data, and the “rotate” button 29 is operated to rotate the image data 90 degrees to select the image data. By operating the “change group” button 30 in this state, the image data can be included in an arbitrary group (step # 102). When image data is selected on the image acquisition screen 27, a finger is brought into contact with a portion of the image data displayed on the display C to acquire a position using the touch panel unit 7, or the remote controller In step 3, the operation of moving the cursor is performed.

  The route storage processing means 14 is configured to always save route data on which the vehicle has traveled. Further, the timing for saving the image data by operating the “acquire image data” button 21 may be set during the traveling of the vehicle, or may be set after the vehicle returns to the home. In addition, in the case where the route data on which the vehicle has traveled is always saved in this way, it is necessary to delete unnecessary route data when the route data is saved near the limit of the storage area capacity. The processing form may be set so that the route data of the old region or the route data considered to be unnecessary is automatically extracted and displayed on the display C to determine whether or not deletion is possible.

  Since the image data displayed in the image display area 27A is displayed in the order in which it was photographed by the digital camera Cam, the image data displayed in the image display area 27A is sequentially sorted even when the image data is divided into groups. The mode is sufficient, and the operation becomes easy. After this grouping is completed, the “next” button 31 is operated to shift to the next processing.

  In the next process, the link edit screen 33 shown in FIG. 5 is displayed on the display C (step # 103). In the link edit screen 33, the route data R along which the vehicle symbol V traveled is displayed together with the map data in the map display area 33A, and a timeline control bar that reproduces the travel of the vehicle is displayed below the map display area 33A. 33B is displayed, and representative image data among a plurality of grouped image data is displayed in the group display area 33C. Further, a “designation” button 34 for performing association, a “cancel” button 35 for canceling designation, a “return” button 36, and a “next” button 37 are displayed in the map display area 33A.

  When the link edit screen 33 is displayed, the operator sets an arbitrary position of the route data R as the destination P and designates a group to be associated with the destination P (step # 104). For this operation, using the touch panel portion 7 of the display C is simple and does not take time, but it is also possible to operate with the remote controller. After this association is completed, the “next” button 37 is operated to shift to the next processing.

  In the next processing, the BGM set screen 40 shown in FIG. 6 is displayed on the display C. When the operator needs it, the “YES” button 41 is operated. When the “NO” button 42 is operated and the “YES” button 41 is operated, the song names stored in the music database are displayed in a list on the song name display unit 43, and when auditioning, the “trial listening” button 44 is displayed. , The music can be auditioned by the speaker 2, and when the music selection is finished, the “OK” button 45 is operated, so that the music data becomes one route data R as BGM. Then, the process proceeds to the next process (Step # 105). When music data is set in this way, different music data may be set for each group.

  In the next processing, a title input screen (not shown) is displayed on the display C, and the processing is ended by inputting necessary characters using the keyboard displayed on the title input screen (step # 106). .

  In this way, the storage form of the image data after the association processing is finished is, for example, a plurality of folders F2 (for example, a group F identification information attached to a folder F1 with a title name as shown in FIG. 10). It can be schematically represented as a structure in which G1, G2, G3. Further, the link data generating means 15 generates link data as shown in FIG. 11, and the link data includes a code number for specifying music data in an area identifiable by a title name, and a relationship between the group G and the destination P. Are stored in text format or CSV format.

  After grouping a plurality of image data in this way and associating each group G with the destination P set in the route data R, the actual travel is performed in which the image data is displayed on the display C when the vehicle is actually traveled. It is possible to display in a mode and a replay mode in which image data is arbitrarily displayed on the display C in a state where the vehicle is stopped.

  That is, as shown in FIG. 3, when the processing menu 20 is displayed on the display C and the “reproduction processing (actual driving mode)” button 22 of this processing menu 20 is operated, the selection screen 47 shown in FIG. When a title to be reproduced is selected from the titles displayed and listed on the display section 48 of the selection screen 47 and the “OK” button 49 is operated, the title is displayed as shown in the flowchart of FIG. Corresponding route data R is designated (step # 201).

  After specifying the route data R, the actual travel mode screen shown in FIG. Only the route data R is displayed on the map data, and the display content of the display C is not different from the normal one indicating the position of the vehicle symbol V (step # 202).

  Thereafter, when the vehicle symbol V approaches the destination P on the route data R due to the traveling of the vehicle, a new window W is opened in a state of overlapping a part of the map data, and a plurality of items associated with the destination P are opened. When the image data is displayed in the preset order at the set intervals and the music data is associated, the music data is reproduced (steps # 203 to # 205).

  This process is configured to be canceled when the operator arbitrarily operates a switch or the like (step # 206).

  When the “reproduction process (replay mode)” button 23 of the process menu 20 displayed on the display C is operated, the selection screen 47 shown in FIG. 7 is displayed as described above, and this selection screen 47 is displayed. By selecting the titles to be reproduced from the titles listed and displayed in the section 48 and operating the “OK” button 49, the route data R corresponding to the titles is designated as shown in the flowchart of FIG. (Step # 301), the replay mode screen is displayed on the display C as shown in FIG.

  In this replay screen, a timeline bar 51 and a plurality of playback control buttons 52 are displayed. When the playback button of the playback control switch 52 is operated or when the timeline bar 51 is operated, the route data R is displayed. When the vehicle symbol V reaches the destination P, the moving state of the vehicle symbol V is displayed in a state where the time is shortened (simulated state), and a new window W is overlapped with a part of the map data. And a plurality of image data associated with the destination is displayed in a preset order at preset intervals (steps # 302 to # 304).

  This process is configured to be canceled by the operator arbitrarily operating a switch or the like (step # 405).

  That is, when the execution mode is selected, when the vehicle approaches the destination P set on the route data R, the image data related to the destination P is displayed on the display C. The passenger can view the image data taken at the destination P visited in the past. In this case, the vehicle does not have to travel on the route data R, and a plurality of image data is automatically displayed every time the vehicle approaches the destination P. When the replay mode is selected, the route data R is displayed on the map data displayed on the display C even when the vehicle is stopped, and the vehicle symbol V is moved and displayed on the route data R. When the vehicle symbol V approaches the destination P, a plurality of image data set at the destination is automatically displayed, so that, for example, image data taken during a trip can be displayed for each destination. .

  The navigation system of the present invention enables automatic display of a plurality of image data by associating the destination P set in the route data R stored as described above with the grouped image data. However, it also has a function of storing the above-described display in the replay mode in a disk-shaped medium Md (an example of a storage medium) such as a DVD-R or a CD-R as data in a format that can be executed by a general household computer. .

  That is, when the “save to media” button 24 is operated from the process menu 20, the process by the save processing unit 17 is executed. That is, the selection screen 5 shown in FIG. 15 is displayed. By selecting items to be saved from the list displayed on the display unit 56 of the selection screen 55 and operating the “OK” button 57, FIG. 16 is displayed. As shown in the flowchart, the route data R corresponding to the title is designated (step # 401). Next, the designated route data R is acquired, the image data associated with the route data R, the associated music data, and the corresponding map data are extracted, and these constitute the output means 16. A process of saving the output program in the disk-shaped medium Md is performed (steps # 402 and # 403).

  In this way, by setting the disc-shaped medium Md in which necessary data is stored in a general home computer, the replay screen described above is displayed on the display C of the computer, and by performing the same operation as described above, A plurality of image data can be displayed for each destination in the form of simulation on a computer.

  As described above, in the present invention, hardware for acquiring image data is added to a conventional navigation system, and a storage (image storage processing means 13) such as a hard disk HD is used. By providing configurable route storage means 14, link data generation means 15, output means 16, and storage processing means 17, the image data taken by the digital camera Cam is grouped and the route data on which the vehicle has traveled is grouped. It becomes possible to associate a plurality of image data grouped for each destination P set to R, and after associating in this way, by selecting the actual driving mode, the vehicle is driven and visited previously. When a vehicle approaches an existing destination P, the system display C automatically It is possible to display the image data and revive the memory of the previous visit clearly, and when the replay mode is selected, the vehicle is stopped and associated with the route data R. A plurality of image data can be displayed on the display C at an arbitrary timing, and the image data can be displayed so as to appreciate the album.

  In particular, when the storage processing means 17 saves the route data R and the image data and the output means 16 configured as an output program for reproducing the same in the disk-like medium Md or the like, the disk-like medium Md is generally stored. It is possible to arbitrarily display a plurality of image data set on the route data R while confirming the state in which the vehicle travels on the map data in the route data R simply by being set on a home computer. It can also be viewed as an electronic album.

[Another embodiment]
The present invention may be configured as follows in addition to the embodiment described above.

(A) When the destination P that has been visited once is visited again and a photograph is taken with the digital camera Cam, the image data can be stored in a form to be added to the already set destination, It is also possible to set the processing form so as to store the image data when the previous visit is added to the point P on the route data when the visit is made again. When such processing is performed, the processing mode at the time of association by the link generation unit 15 may be changed, and when image data is reproduced, past image data and subsequent image data are displayed. Can be appreciated.

(B) When the image data is displayed on the display C, the display form with the map data as the background has been adopted. Instead, the output means 16 displays the image data on the entire screen of the display C. Change the output form. By adopting such a display form, it can be easily viewed with large image data.

(C) In the present embodiment, the method of storing image data in association with each group corresponding to the destination displayed on the link edit screen is adopted, but the present invention is not limited to this, It goes without saying that image data may be associated with registered tourist names and sightseeing maps as a group index so that a plurality of image data can be extracted by designating a sightseeing spot on the navigation map. Further, even when there is no tourist name or tourist map on the route, a processing form may be set so that an arbitrary position in the route can be indicated by a keyboard so that the arbitrary position can be saved as an index.

(D) In the present embodiment, a signal from a GPS satellite is used as the position acquisition means. However, this position acquisition means is the same as the position acquisition method realized by, for example, a PHS mobile phone. In addition, by receiving radio waves from a plurality of radio wave transmission sources installed on the ground, the position of the vehicle may be acquired based on these transmission sources.

(E) In the present invention, as a navigation system, for example, navigation may be performed only by voice without using a display, and when the display is not used in this way, it is conceivable that the navigation route is indicated by voice. . In particular, even a display that does not use a display for navigation requires a display in order to display image data. Further, when route data for associating image data after traveling is extracted, the processing mode may be set so that the route data is extracted from the second storage means by inputting the date and time of traveling.

(F) In the present invention, as route data in which the vehicle is not traveling, it is possible to generate a straight line connecting the destinations with the shortest distance, or arbitrarily generate route data combining a straight line and a curve. The destination is set to the destination, the image data is associated with the destination, and the vehicle is run on the route data, so that it is included in the destination group at the position reached by the vehicle. The processing mode may be set so that the image data is displayed on the display. In particular, the destination may be at an arbitrary position. When the route data is generated in this way and the destination is set, for example, only the route data is displayed without displaying the map data on the display. Each time the vehicle symbol displayed on the route data reaches the destination, the image data included in the destination group is displayed, thereby realizing a simple display.
