The expressway 120 corresponds to the first type road, and the general road 121 corresponds to the second type road.

[Correspondence between wide-area deformed map image and detailed deformed map image]
Here, the correspondence relationship between the wide area deformed map image 250 and the detailed deformed map image 252 in the present embodiment will be described with reference to FIG.

  As described above, the detailed deformed map image 252 is a map image obtained by dividing the wide area deformed map image 250 into nine. Here, in one example of the present invention, each detailed deformed map image 251 includes 9 of the wide deformed map image 250, such as the wide deformed map image 250 and the detailed deformed map images 251A to 251I shown in FIG. It can be a minute relationship. In another example, a detailed deformed map 16 may be displayed when a predetermined condition is satisfied, such as the wide area deformed map image 250 and the detailed deformed map images 252A to 252I shown in FIG. The display area range of the image 252 can be set to a range different from the range obtained by dividing the wide area deformed map image 250 into nine equal parts.

  For example, the detailed map generation unit 16 indicates that an additional object (for example, a road branch) to be displayed within a predetermined range outside a display area of a predetermined detailed deformed map image 252 obtained by dividing the wide area deformed map image 250 into nine equal parts. In some cases, the display range is changed so that the additional object information indicating the additional object can be displayed on the detailed deformed map image 252. Here, the “predetermined range outside the display area” means, for example, a range in which the detailed deformed map image 252 is enlarged at a predetermined ratio (for example, 10%) in the vertical and horizontal directions with respect to the original size. Further, the additional object includes, for example, a large intersection, a facility that serves as a landmark, a landmark such as a building, in addition to the above-described road branch. Moreover, even if it is a normal road as an additional target object, you may make it display the road applicable to said congestion area or a traffic congestion area | region, Furthermore, it is good also considering said camera icon 2 as an additional target object. By doing so, information that is not included in the wide area deformed map image but is included in the detailed deformed map image, such as a congested area, a traffic jam area, and a camera icon, can be displayed more effectively. When there is no additional object to be displayed within a predetermined range outside the display area of the predetermined detailed deformed map image 252 obtained by dividing the wide area deformed map image 250 into nine equal parts, the detailed map generating unit 16 displays the detailed deformed map image 16. The display range of 252 may not be changed.

  FIG. 3C shows an example of a detailed deformed map image 252 obtained by such a change. In this example, there is a branch point of the expressway 120 on the right side of the boundary line 131 when the wide area deformed map image 250 is divided into nine equal parts. Therefore, the detailed map generation unit 16 edits the detailed deformed map image 252 so that the additional object information 132 including the branch point of the expressway 120 is included.

  As a result, the map information providing apparatus 11 has a detailed deformed map image that is useful to the user as compared with the case of providing the detailed deformed map image 251 obtained by simply dividing the wide area deformed map image 250 into nine equal parts. 252 can be provided.

[Edit detailed deformed map image]

And the traffic information acquisition part 14 acquires traffic information (VICS data) from the road traffic information provision apparatus 40 at a predetermined timing.

  Next, as illustrated in FIG. 4B, the detailed map generation unit 16 adds a congested area 101 and a congestion area 102 to the detailed deformed map image 252 based on the traffic information. Then, the detailed map generation unit 16 generates a detailed map file including the detailed deformed map image 252. For the wide area deformed map image 250, the wide area map generation unit 15 generates a wide area map file in the same procedure.

  If there is an intersection 133 between the highway 120 and the general road 121 as shown in FIG. 5 with respect to the above detailed deformed map file, the detailed map generation unit 16 causes the highway 120 to be above the general road 121. A detailed deformed map image 252 that intersects the road and a detailed deformed map image 253 that the general road 121 intersects the highway 120 may be included.

  Thereby, the user of the mobile phone 1 can use two types of detailed deformed map images (the detailed deformed map image 252 and the detailed deformed map image 253) if a predetermined operation is performed. That is, the user can select and display the one with a higher interest among the highway and the general road. Further, a plurality of wide area deformed map images may be included in the wide area map file.

[Providing video information at intersections]
Next, video information provision at an intersection will be described with reference to FIG.

  In the video information provision at the intersection, the map information providing device 11 acquires the video data near the road from the camera device 70 near the road and transmits the video data to the mobile phone 1 in response to a request from the mobile phone 1. It is a process to do.

  First, when the map information providing device 11 transmits a wide area map file to the mobile phone 1 in response to a wide area map file acquisition request from the mobile phone 1, the mobile phone 1 reads the wide area deformed map image 250 in the wide area map file. Is displayed on the display unit 3. When the user performs a predetermined operation on the input unit 4, as shown in FIG. 6A, a part of the wide area deformed map image 250 is selected (a state where there is a focus part 140 indicated by diagonal lines). become.

  When a part of the wide area deformed map image 250 is in a selected state, if the user performs a predetermined operation (for example, pressing the “decision key”) on the input unit 4, The control unit 5 requests the map information providing apparatus 11 to acquire a detailed map file having the detailed deformed map image 252 corresponding to the area where the focus portion 140 is located.

  The map information providing apparatus 11 transmits a detailed map file to the mobile phone 1 in response to a request from the mobile phone 1. When the mobile phone 1 receives the detailed map file, the mobile phone 1 displays the detailed deformed map image 252 in the detailed map file on the display unit 3.

  Then, when the user performs a predetermined operation on the input unit 4, as shown in FIG. 6B, the predetermined camera icon 110 is in a selected state (a state where the focus portion 141 is present).

  When the user performs a predetermined operation (for example, pressing the “decision key”) on the input unit 4 when the camera icon 110 is in the selected state, the control unit 5 of the mobile phone 1 moves to the focus portion 141. A request for transmitting video data of the corresponding camera device 70 is made to the map information providing device 11.

  In response to a request from the mobile phone 1, the map information providing device 11 specifies the camera device 70 to be acquired from the camera installation position information holding unit 17. The camera data acquisition unit 19 requests the specified camera device 70 to acquire video data, and acquires the video data from the camera device 70. The camera data editing unit 20 edits the acquired video data (such as shortening the shooting time), and generates a file including the video data (hereinafter also referred to as “video file”). Then, the map information providing device 11 transmits the video file to the mobile phone 1.

  The mobile phone 1 plays the video data in the acquired video file and displays the playback content on the display unit 3. Here, an example of the reproduction content 260 is shown in FIG.

  Thus, the user of the mobile phone 1 can check the traffic state at the selected position in the form of video data.

[Providing parking status information for parking lots]
Next, provision of parking state information of a parking lot will be described with reference to FIG.

  Here, the provision of the parking state information of the parking lot means that the map information providing device 11 acquires the parking state information from the parking lot information providing device 60 in response to a request from the mobile phone 1 and reflects the parking state information. This is a process of transmitting the map image to the mobile phone 1.

  First, when the user performs a predetermined operation on the input unit 4 while the mobile phone 1 displays the detailed deformed map image 252 on the display unit 3, the mobile phone 1 displays a menu list.

  As a result of the user of the mobile phone 1 operating the input unit 4, when the parking lot menu is selected, the mobile phone 1 makes a parking state map image acquisition request to the map information providing device 11.

  When the map information providing device 11 receives the parking state map image acquisition request from the mobile phone 1, the map information providing device 11 specifies the parking lot targeted for acquisition from the parking location information holding unit 21. The parking lot information acquisition unit 22 acquires parking state information related to the specified parking lot from the parking lot information providing device 60. The parking lot information editing unit 23 generates a parking state map image 261 in which the parking state information acquired by the parking lot information acquisition unit 22 is added to the map data in the storage unit 13. Then, the map information providing apparatus 11 transmits the parking state map image 261 to the mobile phone 1 via the transmission / reception unit 18.

  The mobile phone 1 displays the acquired parking state map image 261 on the display unit 3. A parking lot icon 160 is arranged in the parking state map image 261. Moreover, the parking lot icon 160 is color-coded according to the parking state (full, empty, etc.) as shown in the parking lot icon 160A to the parking lot icon 160C. When the parking lot icon 160 is selected by a predetermined input operation (for example, pressing the up / down key), the mobile phone 1 selects the selected parking lot icon 160 as shown in the wide area parking state map image 261a. Change to 161.

  In addition, the mobile phone 1 is configured to input a wide area parking state map image 261a, a middle area parking state map image 261b, a detailed parking state map image 261c, and a wide area parking state map image by an input operation (for example, pressing the “*” key) by the user. The parking state map image 261 is switched in the order of 261a.

  When the user performs an input operation (for example, pressing the “decision key”) while the selected parking lot icon 161 is displayed, the mobile phone 1 has a parking lot corresponding to the selected parking lot icon 161. Is obtained from the map information providing device 11 and a parking lot detailed information screen 262 including the detailed information of the parking lot is displayed on the display unit 3.

  Thus, the user can list the parking states of a plurality of parking lots in a predetermined area by using the parking state map image 261, and further refer to the detailed information of the predetermined parking lot. can do.

[Edit map image]
Next, editing processing of the map image (the wide area deformed map image 250 and the detailed deformed map image 252) will be described with reference to the flowchart of FIG.

  Here, the map image editing process is a process of adding traffic information to the wide area deformed map image 250 and the detailed deformed map image 252 and regenerating the wide area map file and the detailed map file.

  When the traffic information acquisition unit 14 of the map information providing device 11 makes a traffic information acquisition request to the road traffic information providing device 40 (step S1), the road traffic information providing device 40 sends the traffic information to the map information providing device 11. On the other hand, traffic information is transmitted (step S11).

  When the traffic information acquisition unit 14 acquires the traffic information received from the road traffic information providing device 40, the wide area map generation unit 15 adds the traffic information to the already generated wide area deformed map image 250 (step S2). ). The addition of traffic information here means the color coding of a traffic jam location.

  And the wide area map production | generation part 15 produces | generates the wide area map file containing the said wide area deformed map image 250, and preserve | saves the said wide area map file in the memory | storage part 13 (step S3). Thereby, the map information provision apparatus 11 can hold | maintain the wide area map file reflecting the newest traffic information.

  Next, the detailed map generation unit 16 adds the traffic information acquired by the traffic information acquisition unit 14 to the detailed deformed map image 252 that has already been generated (step S4).

  If there is traffic jam information in the range slightly outside the display area of the current detailed deformed map image 252, the detailed map generating unit 16 adjusts the display range of the detailed deformed map image 252 so that the traffic jam information is included (step S5).

  And the detailed map production | generation part 16 produces | generates the detailed map file containing the said detailed deformed map image 252 and preserve | saves the said detailed map file in the memory | storage part 13 (step S6), and the map information provision apparatus 11 performs map image provision apparatus 11 of the map image. End the editing process. Thereby, the map information provision apparatus 11 can hold | maintain the detailed map file reflecting the latest traffic information.

  In addition, the map information providing apparatus 11 creates a wide area map file and a detailed map file at the timing when the traffic information is updated. Thereby, compared with the case where a wide area map file or a detailed map file is generated when an acquisition request is made from the mobile phone 1, the wide area map file or the detailed map file can be transmitted to the mobile telephone 1 earlier.

[Transmission and reception processing of wide area map file and detailed map file]
Next, transmission / reception processing of the wide area map file and the detailed map file will be described with reference to the flowchart of FIG.

  The cellular phone 1 makes an acquisition request for the wide area map file to the map information providing apparatus 11 in accordance with the user's input operation (step S21). When the map information providing apparatus 11 receives the acquisition request for the wide area map file from the mobile phone 1, the map information providing apparatus 11 transmits the wide area map file stored in the storage unit 13 to the mobile telephone 1 (step S31).
