The address data provided from the address data providing unit 12 includes a zip code.

[Hardware Configuration Example of Information Display Device Embodiment]
Hereinafter, the configuration of the embodiment of the information display device will be described taking the case of the personal computer 2 as an example. FIG. 2 is a block diagram showing a configuration including the functions of the program when the personal computer 2 accesses the map site 1.

  In this example, the personal computer 2 includes a CPU (Central Processing Unit) 201, a ROM (Read Only Memory) 202 for storing programs, and a RAM (Random Access Memory) 203 serving as a work area. It is connected.

  In this example, the system bus 200 further includes a display control unit 204, a display 22, a pointing device interface 205, a communication interface 206, a reception signal processing unit 207, a transmission signal generation unit 208, and a display image correspondence search information storage. A unit 209, a search unit 210, and a movement history storage unit 211 are connected.

  The CPU 201 controls the overall operation of the personal computer 2. The ROM 202 stores a program for executing various control processes in the personal computer 2. The CPU 201 uses the RAM 203 as a work area memory and executes control processing according to the program stored in the ROM 202.

  The display control unit 204 is connected to the display 22, generates a display image to be displayed on the display screen of the display 22, and performs display control. In this embodiment, as will be described later, the display control unit 204 superimposes and displays an address marker including an icon having a predetermined size and a predetermined shape on a map image. The position of the address marker on the map image is configured to be dragged and moved by the mouse 23, and the display control unit 204 displays the address marker at the position on the map according to the drag operation by the mouse 23. Like that.

  In this embodiment, the display control unit 204 includes an address register (not shown) that stores address data to be displayed corresponding to the address marker, and the address sent from the search unit 210 to this address register. Write the address data of the location on the map pointed to by the marker. Then, the display control unit 204 superimposes and displays the address data of the address register on the map image together with the address marker as will be described later.

  In this example, a mouse 23 is connected to the pointing device 205, and operation information such as a cursor movement operation, a click operation, and a drag operation by the mouse 23 is transmitted to the CPU 201 through the system bus 200.

  The communication interface 206 is an interface for accessing the map site 1 and the like through the communication network 4. The reception signal processing unit 207 is a function processing unit that analyzes a reception signal received through the communication interface 206 under the control of the CPU 201 and supplies the analysis signal to the display control unit 204 or to the search unit 210.

  The transmission signal generation unit 208 is a function processing unit that generates a transmission signal to be transmitted through the communication interface 206 under the control of the CPU 201.

  The display image correspondence search information storage unit 209 stores and holds search information corresponding to each image position of the display image, which is included in the information acquired from the map site 1, as will be described later. In this example, the display image correspondence search information storage unit 209 stores and holds information on latitude and longitude corresponding to each position on the map image displayed on the display screen of the display 22 as search information. In this example, when the map image displayed on the display screen of the display 22 is changed, the information stored in the display image correspondence search information storage unit 209 is changed according to the change.

  Note that the map information, which is a display image, also includes information on the latitude and longitude corresponding to the position on each map, so the display position of the position on the map on the display screen is based on the information on the latitude and longitude. Can be taken.

  The search unit 210 corresponds to the program acquired from the map site 1, and from the map site 1 using the search information acquired from the display image-corresponding search information storage unit 209, in this example, latitude and longitude information. , A function processing unit for acquiring a corresponding search result. In this example, the search unit 210 receives information on the position on the map image where the address marker is placed from the display control unit 204, and uses the information on the position from the display image correspondence search information storage unit 209. Information on the latitude and longitude of the position on the map where the address marker is placed is acquired, and it is sent as search information to the address data providing unit 12 of the map site 1 to make a search request. Address data as a search result Is acquired from the address data providing unit 12. Then, the acquired address data is passed to the display control unit 204 and the movement history storage unit 211. The search unit 210 stores the URL (Uniform Resource Locator) of the address data providing unit 12.

  When the address data received from the search unit 210 is different from the previous address held in the address register, the display control unit 204 rewrites the contents of the address register with the received address data. Note that the display control unit 204 may overwrite the address register with the address data received from the search unit 210.

  When the address data acquired by the search unit 210 from the address data providing unit 12 is different from the previous address held in the address register, the movement history storage unit 211 additionally stores the address data. In this case, the movement history storage unit 211 associates each address data with information for specifying the corresponding position on the map, in this example, the information on the latitude and longitude of the address, and the movement history storage unit In 211, the data is additionally stored. In addition to the latitude and longitude information, mesh information may be stored in association with each other.

  The address data stored in the movement history storage unit 211 is displayed in a list format on the display screen of the display 22 via the display control unit 204.

  In the configuration of the personal computer 2 in FIG. 2, the processing functions of the display control unit 204, the reception signal processing unit 207, the transmission signal generation unit 208, and the search unit 210 are software executed by the CPU 101 in accordance with the software program. Although it can be configured as a function, it is described as a functional block for convenience.

[Outline of Address Search Processing Operation in Embodiment]
Next, the outline of the address search processing operation in the personal computer 2 as an example of the information display device of this embodiment will be described with reference to FIG. 3 which is a display example on the display screen of the display 22. That is, FIG. 3 shows an example in which a display image sent from the map site 1 is displayed as a window image when the personal computer 2 accesses the map site 1 and requests provision of a service with an address search function. Is.

  This display image includes a map image display field 51 and a usage description and movement history display field 52. A map image 53 is displayed in the map image display field 51, and an address marker 54 and a balloon display unit 55 are superimposed on the map image 53.

  The address marker 54 is composed of icons having a predetermined size and a predetermined shape. The address marker 54 can be dragged by moving the cursor within the size range of the address marker 54 with the mouse 23 and performing a drag operation. The address marker 54 can be moved on the map image by moving the cursor while dragging. Therefore, the operation of dragging the address marker 54 is an operation instruction for moving the address marker.

  In this example, the address marker 54 has a shape including a triangular protrusion 54a, and the apex of the triangular protrusion 54a indicates the position on the map where the address marker 54 is placed. Yes. In the balloon display section 55, the address at the position on the map indicated by the address marker 54 is displayed together with the postal code.

  In this example, when the user drags and moves the address marker 54, the balloon display unit 55 also moves together with the address marker. When the address marker 54 moves, the address displayed on the balloon display unit 55 is changed in accordance with the change of the position on the map indicated by the address marker 54. In this case, every time the address marker 54 moves by a predetermined distance on the display screen, the search unit 210 obtains the latitude and longitude corresponding to the position indicated by the moved address marker 54 from the display image correspondence search information storage unit 209. Obtain the latitude and longitude as search information and make a search request to the address data providing unit 12 of the map site 1. When the address data acquired as a search result from the address data providing unit 12 is different from the address data at the previous position, the address displayed on the balloon display unit 55 is changed to the acquired new address. Further, in this example, the acquired new address data is additionally stored in the movement history storage unit 211 in association with the latitude and longitude information of the address.

  When the user releases the drag, the address marker 54 is fixed at the position on the map. The address of the balloon display section 55 is also fixed in a state where the address at the position on the map pointed to by the address marker 54 is displayed.

  As described above, when the address marker 54 is dragged and moved, the address in the balloon display section 55 is changed and displayed each time the address changes as it moves. Accordingly, it is possible to easily perform an operation such as moving the address marker 54 closer to the target address while viewing the address on the balloon display unit 55.

  In this example, when an arbitrary position of the map image other than the address marker 54 is dragged and moved in an arbitrary direction, the entire map image 53 can be moved in the moving direction. That is, the map image 53 displayed in the display column 51 can be changed in the dragged direction. At this time, the address marker 54 and the balloon display unit 55 move together with the map image 53. When the map image is moved, if the personal computer 2 has already acquired all of the moved map data from the map data providing unit 11, the map image is displayed using the acquired map data. However, when the map data after movement has not yet been acquired, the personal computer 2 makes a request for acquiring the map data after movement to the map data providing unit 11 of the map site 1 to acquire the map data. The map image 53 is displayed.

  If the position where the address marker 54 is placed is outside the range of the map image display field 51 due to the movement of the map image, the address marker 54 and the balloon display unit 55 are out of the display field 51.

  Next, a description 56 of how to use the address marker 54 is displayed in the usage description and movement history display field 52, and a center movement icon button 57 is displayed. When the user clicks the center movement icon button 57 with the mouse 23, the address marker 54 is configured to move to the center of the map image 53 being displayed in the display field 51. Thereby, even if the position on the map of the address marker 54 and the balloon display portion 55 is outside the display column 51, the address marker 54 can be returned to the center position on the currently displayed map image. it can. At this time, the address at the center position after the movement is displayed on the balloon display section 55 attached to the address marker 54. Then, the movement history storage unit 211 additionally stores the address data of the center position after the movement as the latest address data in association with the information of the latitude and longitude.

  In the usage description and movement history display field 52, the address of each position on the route on which the address marker 54 has moved, which is stored in the movement history storage unit 211, is used as the movement history of the address marker. Are displayed in list format. In this case, in the address list, the address at the latest position of the address marker 54 is displayed at the top of the list, the second new address below it, the third new address below it, and so on. In order of new address.

  It should be noted that the list of the movement history display unit 58 can be viewed by scrolling the list by operating the slide bar 59.

  Then, when the user selects (for example, clicks) one address in the list of the movement history display unit 58, a map image 53 in which the position of the selected address becomes the center position is displayed in the display field. The address marker 54 is moved to the position of the selected address which is the center position of the map image 53. Then, the selected address is displayed on the balloon display portion 55 and the selected address is displayed at the top of the list of the movement history display portion 58. This process is performed based on the latitude and longitude information stored in the movement history storage unit 211 corresponding to the selected address data. That is, the map image 53 is displayed in the display column 51 so that the latitude and longitude corresponding to the selected address data are the center position of the map image 53 in the display column 51. In this case, when the map data of the map image 53 to be newly displayed has not yet been acquired, the personal computer 2 requests the map data providing unit 11 of the map site 1 to acquire the map data, and The map data is acquired in the same manner as described above.

  As described above, the address of the balloon display section 55 changes as it moves, but a list of addresses that change with the movement is sequentially displayed in the movement history display section 58. By referencing, it is also possible to find out the desired address from the movement history list of the movement history display section 58. When the desired address location is found, clicking on the display of the address to select it enables the map image 53 to be changed to a map display centered on the address location, which is very convenient.

[Example of address search processing operation on PC 2]
Next, the flow of processing operations of the personal computer when executing the address search as described above will be described with reference to the flowcharts of FIGS. The processing of each step described below is performed by the CPU 201 executing according to the program acquired from the map site 1 using the RAM 203 as a work area. That is, the processing example of the following flowchart is a case where the CPU 201 executes the processing functions of the display control unit 204, the reception signal processing unit 207, the transmission signal generation unit 208, and the search unit 210 as software functions.

  First, the CPU 201 determines whether or not an operation instruction to access the map site 1 is given by the user (step S101). If it is determined in this step S101 that an instruction to access the map site 1 has not been issued, the CPU 201 proceeds to another processing routine (step S102), and when that processing routine ends, the CPU 201 returns to step S101.

  When it is determined in step S101 that an instruction to access the map site 1 has been issued, the CPU 201 displays a service list sent from the map site 1 (step S103). Next, the CPU 201 determines whether or not a map service with an address search in the service list has been selected (step S104), and when a map service other than the map service with an address search is selected, the selected service is determined. The processing routine is shifted to (Step S105). In this embodiment, since the map service with address search is described, the detailed description of step S105 is omitted.

  If it is determined in step S104 that the map service with address search has been selected, the CPU 201 sends a request for the map service with address search to the map site 1 (step S106). Then, since the map image information on which the address marker 54 and the balloon display unit 55 are superimposed is sent from the map site 1, the CPU 201 displays a window for displaying the map image 53 on the display screen of the display 22. The information is displayed in the display field 51 (step S107). At this time, the address at the position indicated by the address marker 54 is displayed on the balloon display unit 55 and the address is displayed in a list on the movement history display unit 58.

  Next, the CPU 201 determines whether or not the user has dragged the mouse 23 on the map image 53 (step S108), and when determining that the drag operation has been performed, the drag operation is performed on the address marker 54. It is determined whether or not it has been made (step S109).

  When it is determined that the drag operation is not performed on the address marker 54, the CPU 201 determines whether or not the drag is moved (step S110). When it is determined that the drag is moved, a display field is displayed. 51 map images 53 are moved in the moved direction (step S111). At this time, as described above, when the map data of the map image 53 to be newly displayed has not yet been acquired, the CPU 201 makes a request for acquiring the map data to the map data providing unit 11 of the map site 1. The map data is acquired.

  Then, the CPU 201 determines whether or not the drag is released (step S112). When it is determined that the drag is released, the process returns to step S108, and the processes after step S108 are repeated. If it is determined in step S110 that the drag has not been released, the CPU 201 returns the process to step S110 and repeats the processes after step S110.

  If it is determined in step S110 that the drag has not been moved, the CPU 201 advances the process to step S112 to determine whether the drag has been released. And the process after this step S112 is repeated.

  Next, when it is determined in step S109 that the drag operation has been performed on the address marker 54, the CPU 201 determines whether or not the drag is released (step S121 in FIG. 5), and when it is determined that the drag is released. The process returns to step S108, and the processes after step S108 are repeated.

  When it is determined in step S121 that the drag has not been released, the CPU 201 monitors the movement of the address marker 54 on the display screen (movement while dragging) (step S122). And it discriminate | determines by whether the position of the dragged address marker 54 changed more than predetermined length on the display screen (step S123).

  When it is determined in step S123 that the position of the address marker 54 has not changed by a predetermined length or more on the display screen, the CPU 201 returns to the processing step S121 and repeats the processing after step S121. The processing from step S121 to step S123 is repeated, for example, every second.

  When it is determined in step S123 that the position of the address marker 54 has changed by a predetermined length or more on the display screen, the CPU 201 uses the function of the search unit 210 to determine the latitude and longitude corresponding to the moved position of the address marker 54. Is acquired from the display image correspondence search information storage unit 209. Then, an address data acquisition request is sent to the address data providing unit 12 (server) using the acquired latitude and longitude as search information (step S124).

  And CPU201 acquires the address data sent from address data offer part 12 (Step S125). Then, the CPU 201 determines whether or not the acquired address data is different from the address before moving (address data in the address register) currently displayed on the balloon display unit 55 (step S126). If so, the process returns to step S121, and the processes after step S121 are repeated.

  If it is determined in step S126 that the acquired address data is different from the pre-movement address currently displayed on the balloon display unit 55, the CPU 201 rewrites the address data in the address register, and displays the balloon display unit 55. Is changed to the acquired new address data (step S127). In addition, the CPU 201 additionally stores the latitude and longitude corresponding to the moved address marker position and the acquired new address data (including the zip code) in the movement history storage unit 211 (step S128). And the control part 201 displays the new address after a movement on the top of the movement history display part 58 (step S129). And CPU201 returns a process to step S121, and repeats the process after this step S121.

  If it is determined in step S108 in FIG. 4 that the user has not dragged the mouse 23, the CPU 201 determines whether or not the center movement icon button 57 has been clicked (step S131 in FIG. 6).

  When it is determined in step S131 that the center movement icon button 57 has been clicked, the CPU 201 moves the address marker 54 to the center of the map image 53 without moving the map image 53 (step S132). Then, the CPU 201 acquires the latitude and longitude corresponding to the moved position of the address marker 54 from the display image correspondence search information storage unit 209 by the function of the search unit 210. Then, an address data acquisition request is sent to the address data providing unit 12 (server) using the acquired latitude and longitude as search information (step S133).

  And CPU201 acquires the address data sent from address data offer part 12 (Step S134). Then, the CPU 201 determines whether or not the acquired address data is different from the address before movement (address data in the address register) currently displayed on the balloon display unit 55 (step S135). When this happens, the address of the balloon display unit 55 remains unchanged (step S139), the process returns to step S108, and the processes after step S108 are repeated.

  If it is determined in step S135 that the acquired address data is different from the pre-movement address currently displayed on the balloon display unit 55, the CPU 201 rewrites the address data in the address register, and displays the balloon display unit 55. Is changed to the new address data acquired (step S136). Next, the CPU 201 additionally stores the latitude and longitude corresponding to the moved address marker position and the acquired new address data (including the zip code) in the movement history storage unit 211 (step S137). And the control part 201 displays the new address after a movement on the top of the movement log | history display part 58 (step S138). And CPU201 returns a process to step S108, and repeats the process after this step S108.

  If it is determined in step S131 that the center movement icon button 57 has not been clicked, the CPU 201 determines whether one of the addresses in the list display of the movement history display unit 58 has been selected and clicked ( Step S141 in FIG.

  If it is determined in step S141 that one of the addresses displayed in the list of the movement history display unit 58 has been selected, the map image 53 is changed so that the position of the selected address becomes the center position (step S142). ). Also at this time, when the map data of the map image 53 to be newly displayed has not been acquired yet, the CPU 201 requests the map data providing unit 11 to acquire the map data, and acquires the map data. Like that.

  Next, the CPU 201 moves the address marker 54 to the selected address position, that is, the center position on the new map image 53, writes the address data of the selected address position in the address register, and displays the balloon. The selected address is displayed on the part 55 (step S143). Thereafter, the CPU 201 returns the process to step S108, and repeats the processes after step S108.

  If it is determined in step S141 that an operation for selecting one of the addresses displayed in the list of the movement history display unit 58 has not been performed, the CPU 201 determines whether an operation for starting another process has been performed (step S141). S144) When it is determined that the start operation of the other process has been performed, the other process is executed (step S145). Then, the CPU 201 returns the process to step S108 after the completion of the other processes, and repeats the processes after step S108.

  If it is determined in step S144 that no other process start operation has been performed, the CPU 201 determines whether an end operation has been performed (step S146). If it is determined that no end operation has been performed, the process is performed. Returning to step S108, the processing after step S108 is repeated. If it is determined in step S146 that an end operation has been performed, the CPU 201 performs an end process of this processing routine (step S147).

[Effect of the first embodiment]
As described above, according to the information display device of this embodiment, only the address marker is superimposed and displayed on the map image, and the address at the position where the address marker is placed is superimposed and displayed. Operation such as clicking the position with the mouse becomes unnecessary. When the address marker is moved, the moving address can be moved while being displayed, which is very convenient when searching for the target address.

  In addition, when the address marker is moved, the position where the address marker has passed is displayed as a list of addresses as a history, which is also useful when searching for a target address. .

  Further, in the above-described embodiment, when one address is selected from the address list of the movement history, a map image centered on the address location can be displayed, so that an efficient search is possible.

  In the above-described embodiment, it is convenient because the address marker can be easily moved to the center position on the map image by operating the center movement icon button.

[Modification of First Embodiment]
In the above-described embodiment, when the dragged address marker 54 moves by a predetermined distance on the screen, the address marker 54 is moved, and the address data is acquired for the position after the movement. When the address marker 54 is dragged, the address data may be acquired at regular intervals until the drag is released.

  Since the description of the first embodiment described above is for the case where the information display device is a personal computer, the operation means is for a mouse. However, when the mobile phone terminal 3 shown in FIG. 1 is an information display device, an operation of pointing the address marker displayed on the display screen 31 with a finger and moving it as it is is dragged with the touch panel 32. By setting the operation, it is possible to realize the same processing operation as that described in the above embodiment.

  In the above description of the first embodiment, only one address marker is used. However, a plurality of address markers may be displayed simultaneously on one map image. In that case, the movement history 86 is divided into a plurality of pieces and displayed in correspondence with each address marker.

  In the above-described embodiment, the search result information related to the position is an address, but the search result information related to the position is not limited to the address. For example, a restaurant or tourist spot around the position where the marker is placed may be used as search result information related to the position.

  Further, in the above-described embodiment, the marker corresponds to one predetermined search result information related to the position. However, as described above, since various kinds of information can be assigned and set for the search result information related to the position, it is possible to select what information is searched using the marker. May be.

  For example, as shown in FIG. 8, an address search marker 61, a restaurant search marker 62, and a sightseeing spot search marker 63 are displayed on the image acquired first from the map site 1, and any of the markers is displayed. May be selected. In this case, for example, when the user selects the address search marker 61 and clicks the start icon button 64, the display screen shown in FIG. 2 is displayed and the search operation described above can be started. Note that any of the markers may be dragged and moved onto the map image, the drag may be released, and the marker may be placed on the map image to start the above-described search operation.

  Also, as shown in FIG. 9, a list of search items that can be selected may be displayed on a balloon display unit 72 attached to the marker 71 that is superimposed on the image acquired first from the map site 1. . In the case of the example in FIG. 9, when address search is selected from the list, for example, the display screen shown in FIG. 2 is displayed and the search operation described above can be started. In this case, the list balloon display 72 is changed to a balloon display 73 for displaying addresses.

[Second Embodiment]
In the first embodiment, the display image is a map image, and the latitude and longitude corresponding to the position on the map are used as search information. However, the present invention is not limited to the case where the display image is a map image.

  For example, when searching for the meaning and content of a predetermined term as a target of a search result, a link tag is combined with the predetermined word / phrase in the sentence of the search result, and the word / phrase is selected. In some cases, the link tag can be used to search the meaning of the phrase. The present invention can be applied when searching for a phrase in such a sentence.

  In this type of conventional phrase search, when a phrase to which a link tag is linked is clicked, the server specified by the URL included in the link tag is accessed, and the search result for the phrase is sent from that server. . At this time, the display screen is switched to a screen for displaying a search result newly sent from the server in response to the click of the phrase, and the original display image is deleted.

  On the other hand, in the second embodiment, by using the phrase marker, it is possible to display the meaning of the phrase where the phrase marker is located while securing the display image of the original term search result. . In the second embodiment, the meaning of words passed by moving the phrase marker can be displayed in a list in the movement history, so that the contents can be displayed as a list.

  For example, FIG. 10 shows an example of a display image (window image) when a personal computer accesses a term search site and acquires a search result for the term. The display image in the example of FIG. 10 includes a text display field 81 of search results and a usage description and movement history display field 82. In this example, the search result text display field 81 displays a text image 83 of the search result for the term “national park”. In this example, a plurality of word markers 84a and 84b and balloon display portions 85a and 85b associated with the word markers 84a and 84b are superimposed and displayed in the text display field 81 of the search result. .

  Like the address marker 54, the phrase markers 84a and 84b are made of icons having a predetermined shape, and can be moved by moving the cursor to the position of the phrase markers 84a and 84b with the mouse. In each of the balloon display portions 85a and 85b, the meanings and explanations of the words to which the link tags are combined are indicated by the word markers 84a and 84b.

  In the second embodiment, the link tag is search information prepared corresponding to the image position of the display image, and is stored in the display image correspondence search information storage unit of the first embodiment. Information.

  In this second embodiment, when the phrase marker 84a or 84b is dragged and moved, every time the phrase tag is passed through the portion of the phrase to which the link tag is linked, the link tag that is linked to the passed phrase is changed. Obtained from the display image correspondence search information storage unit. Then, the acquired link tag is used to access the server to acquire the meaning and explanation of the phrase, and the meaning and description of the acquired phrase are displayed on the balloon display section 85a or 85b. Further, in this example, the meaning and explanation of the acquired word / phrase are sequentially stored in the movement history storage unit corresponding to each word / phrase. The contents stored in the movement history storage unit are displayed as a list as a movement history display unit 87 as shown in FIG.

  In this example, when one of the movement history display parts 87 displayed in the list is selected and clicked with the mouse, the word marker 84a or 84b moves to the position of the word, and its meaning and explanation are displayed in the balloon display part. It is displayed in 85a or 85b.

  If not all of the meaning and explanation of the word can be displayed on the balloon display section 85a or 85b, the cursor is positioned on the balloon display section 85a or 85b, and the scroll operation is performed, so that the meaning or explanation of the word or phrase is displayed. You can scroll and read all of them.

[Third Embodiment]
In the first embodiment described above, when the marker is moved by dragging, information related to the position such as the address of the position where the marker has moved is always acquired from the server in the movement history storage unit, and the movement history display unit To be displayed.

  However, when the user moves by dragging the marker and the moving speed is relatively fast until the drag is released (dropped) at a predetermined post-movement position, the intention of the user is halfway from dragging to dropping. It is considered that there are many cases where the user is not interested in the information on the movement route of the user and is interested only in the search result of the drop position. Conversely, when the user drags the marker and moves it relatively slowly (including zero movement speed), it is considered that the user intends to move to the drag release position while searching for information on the movement path.

  Therefore, in the third embodiment, in consideration of this point, the movement speed when the user gives an operation instruction for moving the marker by dragging the marker is detected, and the detected movement is detected. When the speed is equal to or lower than the predetermined speed Vth (Vth ≧ 0), the search result during movement is displayed and the movement history is stored as in the above-described embodiment. The reference reference predetermined speed Vth with respect to the movement speed of the marker includes Vth = 0, which means that the movement of the marker is stopped while the marker is dragged.

  On the other hand, in the third embodiment, when the moving speed when the user gives an operation instruction for moving the marker by dragging the marker to the marker is higher than the predetermined speed Vth, in the third embodiment, the information display device The search during movement is not performed. Therefore, the search result during movement is not displayed, and the movement history information during movement is not stored.

  In the third embodiment, the search target is not the address of the position where the marker exists, but the information of restaurants such as restaurants around the position where the marker is placed. Therefore, in the following description of the third embodiment, the marker is referred to as a store marker.

[Outline of Third Embodiment]
FIG. 11 is a diagram showing an outline of an example of a communication system including the third embodiment of the information display device of the present invention. The information display device of the third embodiment is the same as that of the first embodiment. It is set as the same structure. That is, as shown in FIG. 11, the information display apparatus according to the third embodiment is similar to the first embodiment, using a personal computer 2 or a mobile phone terminal 3 connected to the map site 1 through the communication network 4. Composed. However, the map site 1 includes a store data providing unit 13 instead of the address data providing unit 12 in the third embodiment.

  The store data providing unit 13 includes a database that stores store information for each store of various genres in association with each store ID (identification information). The store information includes the location information (latitude and longitude) of each store, the store name, and detailed information such as an address, the contents of the provided product and the provided service. In this embodiment, when the store data providing unit 13 receives a store search request including search information (search conditions) as described later from the information display device, the store data providing unit 13 searches for stores that match the search information, and A list of store names is sent to the information display device as search result information.

  The information display device according to the third embodiment includes, as search information corresponding to each position (image position) on the map, in addition to the information on the latitude and longitude of the position on the map where the store marker is displayed, Area range information centered on the position on the map and store genre information are prepared, and a store search request is sent to the store data providing unit 13 of the map site 1. In this embodiment, the area range information and genre information are configured to be set by the user in the information display device. The store genre information is selected from genres for predetermined stores such as a ramen store, a sushi store, a curry store, and a convenience store.

  When the store data providing unit 13 of the map site 1 receives a store search request from the information display device of the third embodiment, the store data providing unit 13 is designated by area range information centered on the position specified by the latitude and longitude information. The store of the genre specified by the genre information existing within the range is searched, and a list of store names of stores that match the search information is returned to the information display device as the search result information. In this embodiment, the store data providing unit 13 also transmits distance information indicating how far each store is away from the center of the area range, together with a list of store names, to the information display device as search result information.

  In the third embodiment, as will be described later, the store data providing unit 13 searches the store marker movement history so that the address data at the position indicated by the store marker is also a list of store names. At the same time, it has a function of providing the information display device as search result information. Therefore, the store data providing unit 13 also has the function of the address data providing unit 12 of the first embodiment.

  Further, the store data providing unit 13 also has a function of providing detailed information of a store when receiving a search request for information on one store in the store list from the information display device. The information display device of the third embodiment receives information on the search result from the store data providing unit 13, and the display image on the display screen of the display reflects the search result.

  As described above, in the information display device of the third embodiment, when the moving speed Vs of the store marker by the user is equal to or lower than the predetermined speed Vth, a process of sending a store search request to the store data providing unit 13 is executed. On the other hand, when the movement speed of the store marker is higher than a predetermined speed, the information display device does not transmit a store search request to the store data providing unit 13 during the movement.

  For this reason, in the third embodiment, when the store marker is dragged, the store marker moving speed Vs = D / T is always detected by detecting the store marker moving distance D every fixed time T, for example. To monitor.

  Similarly to the case of the first embodiment, when the store marker has not moved from the position where the search request is made to the map site 1, a search request is sent again to the map site 1 from the same position. Since it is useless, in this embodiment, a search request is sent to the map site 1 only at a position moved more than a significant distance. For this reason, in the information display device according to the third embodiment, each time the store marker moves more than a predetermined distance corresponding to the significant distance, the movement speed of the store marker that is separately monitored Refer to

  When the moving speed Vs of the store marker by the user's moving operation is equal to or lower than the predetermined speed Vth, a store search request is sent to the store data providing unit 13 of the map site 1. Then, as will be described later, the information display device displays store list information based on the store search result information received from the store data providing unit 13 on the display screen of the display. Therefore, the display content of the store list information on the display screen of the display is changed every time the moving store marker stops or every time the slowly moving store marker moves a predetermined distance. When the drag of the store marker that has been dragged is released and dropped, the store list information at the drop position is continuously displayed on the display screen of the display.

  At this time, the information display device associates the information of the store search result acquired from the store data providing unit 13 at each position in the middle of movement with the information of the position and holds it as history information. In the third embodiment, the information on the store search result during the movement is configured so that the user can know later based on the movement history display operation of the user, as will be described later. ing.

  On the other hand, when the moving speed of the store marker by the user is higher than the predetermined speed Vth, the information display device does not transmit a store search request to the store data providing unit 13 during the movement. For this reason, the information display device does not store and retain history information during movement.

  Then, when the dragged store marker stops moving and is dropped, the information display device sends a store search request to the store data providing unit 13 at the drop position, and displays the store search result at the drop position. Receive information. Therefore, at this time, the store list information on the display screen of the information display device is changed from the position where the store marker is dragged to the drop position.

  In addition, when the moving speed of the store marker is changed from a state higher than the predetermined speed Vth to a predetermined speed Vth or less during the movement, the history information described above is retained from the position where the moving speed becomes the predetermined speed or less. It goes without saying that the processing operation is shifted to.

  Next, a hardware configuration example and processing operation of the information display apparatus according to the third embodiment will be described below by taking the case where the information display apparatus is the personal computer 2 as an example.

[Example of Hardware Configuration of Information Display Device of Third Embodiment]
An example of the hardware configuration of a personal computer 2 as an example of the information display device of the third embodiment is shown in FIG. The personal computer 2 as an example of the information display device of the third embodiment has substantially the same configuration as the personal computer 2 in the first embodiment shown in FIG. Different from the embodiment.

  In the third embodiment, under the control of the CPU 201, the display control unit 204 superimposes and displays a store marker composed of an icon having a predetermined size and a predetermined shape on a map image, as will be described later. To. The position of the store marker on the map image is configured to be moved by being dragged by the mouse 23, and the display control unit 204 displays the store marker at the position on the map according to the drag operation by the mouse 23. Like that.

  In the third embodiment, the display control unit 204 includes a store data register (not shown) that stores a part of store data to be displayed corresponding to the store marker. A part (1 store) of the store data sent from the unit 210 is written. Then, the display control unit 204 displays the store data based on the store data in the store data register on the display screen of the display 22 in a balloon unit attached to the store marker, as will be described later.

  In the third embodiment, the display image correspondence search information holding unit 209 also includes latitudes corresponding to respective positions on the map image displayed on the display screen of the display 22, as in the first embodiment. The longitude information is stored and held as search information, and as described above, the area range information and genre information are also stored and held as search information.

  Also, in the third embodiment, the search unit 210 is a function processing unit based on a program acquired from the map site 1 as in the first embodiment, but the search target requested from the map site 1 is As described above, it differs from the first embodiment in that it is store data, not address data, and that it includes a search operation activation determination unit 2101 as shown in FIG.

  The search operation activation determination unit 2101 is configured as software function processing means by the CPU 201. The search operation activation determination unit 2101 monitors the behavior of the mouse 23 through the pointing device interface 205, and stores the store marker when the store marker is dragged by the mouse 23. The moving speed Vs of the marker is monitored. That is, when the store marker is dragged, the search operation activation determination unit 2101 detects the store marker moving distance D every fixed time T, and always detects the store marker moving speed Vs as Vs = D / T. To monitor.

  Then, every time the store marker moves by a predetermined distance or more corresponding to a significant distance, the search operation activation determination unit 2101 refers to the movement speed Vs of the store marker that is being monitored. Whether to activate 210 is determined. That is, when the movement speed Vs of the dragged store marker is higher than a predetermined speed Vth, the search unit 210 is not activated. The search operation activation determination unit 2101 activates the search unit 210 when the moving speed Vs of the dragged store marker is equal to or lower than a predetermined speed Vth. Furthermore, the search operation activation determination unit 2101 activates the search unit 210 when the dragged store marker is dropped.

  In this third embodiment, when the search unit 210 is activated, the latitude, longitude, area range, and genre of the position of the store marker as the search information acquired from the display image correspondence search information storage unit 209 are activated. A store search request including information is sent to the map site 1, and information on stores of a specified genre that exists within a specified area range centered on the position indicated by the latitude and longitude from the map site 1 is sent. , To get as search result information. Then, the acquired store data is passed to the display control unit 204 and the movement history storage unit 211. In addition, the search unit 210 acquires address data corresponding to the latitude and longitude of the position of the store marker when the store search request is transmitted from the store data providing unit 13 and passes the address data to the movement history storage unit 211. To. The search unit 210 stores the URL of the store data providing unit 13.

  In this embodiment, the movement history storage unit 211 includes a store marker movement history storage unit 2111 and a store list data storage unit 2112 as shown in FIG. The store marker movement history storage unit 2111 stores the address data corresponding to the latitude and longitude of the position of the store marker (center position of the area range) acquired by the search unit 210 from the store data providing unit 13 in response to the store search request. Stored in association with the position (latitude and longitude information) of the store marker when the store search request is issued. Therefore, in the store marker movement history storage unit 2111, the address of each position at which the store search request is sent from the information display device to the store data providing unit 13 and the search result is obtained in the store marker movement route is the movement route. Are stored sequentially.

  The store list data storage unit 212 associates the store data acquired from the store data providing unit 13 in response to the store search request with the position (latitude and longitude information) of the store marker when the store search request is issued. Remember. Therefore, in the store list data storage unit 212, store information at each position where a store search request is sent from the information display device to the store data providing unit 13 and the search result is acquired in the store marker moving route is stored in the moving route. Are stored sequentially.

  The configuration and operation of other processing blocks of the personal computer 2 are substantially the same as those in the first embodiment described above.

[Store Search Processing Operation of Personal Computer 2 as an Example of Information Display Device of Third Embodiment]
FIG. 13 shows an example in which a display image sent from the map site 1 is displayed as a window image when the personal computer 2 accesses the map site 1 and requests provision of a service with a store search function. is there. With reference to FIG. 13, an outline of the store search processing operation of the personal computer 2 as an example of the information display device of the third embodiment will be described.

  As shown in FIG. 13, the display image includes a map image display field 501 and a search condition and search result display field 502. A map image 503 is displayed in the map image display field 501, and a store marker 504 and a balloon display unit 505 are superimposed on the map image 503.

  In this example, the store marker 504 has a shape including a triangular protrusion 504a, and the apex position of the triangular protrusion 504a is a position on the map indicated by the store marker 504. Then, for example, a circular area around the position on the map indicated by the store marker 504 is set as the area range to be searched. In this example, the area range is displayed on the map image 503 by a semi-transparent area range display unit 506 of a predetermined color, and is notified to the user.

  Note that the area range display unit 506 is not limited to being displayed in a predetermined translucent color as in this example, and may be displayed in any display mode as long as the area range can be specified. good. For example, only the frame of the area range may be displayed as a matter of course.

  In the third embodiment, the balloon display unit 505 displays part of the store information acquired from the store data providing unit 13 by the personal computer 2 at the position indicated by the store marker 504. indicate. Further, when the moving speed Vs in the state where the store marker 504 is dragged is equal to or lower than the predetermined speed Vth, the balloon display unit 505 includes, among the store information acquired from the store data providing unit 13 at the position during the movement. Store information of one store is displayed. In the example of FIG. 13, the store name of one store among the store information acquired from the store data providing unit 13 is displayed on the balloon display unit 505.

  In the search condition and search result display field 502, an area range input field 507, a genre input field 508, a store list display field 509, and a history display icon button 510 are displayed.

  In this example, the area range input field 507 is an input field for inputting the radius of the circular area range centering on the store marker 504, which is one of the search information, and the user clicks with the mouse. Thus, a list of selectable radii can be displayed in a pull-down manner. Then, the user can set a circular area range by selecting a desired radius value from the pull-down radius list.

  In this example, the genre input field 508 is an input field for the genre of the store to be searched, which is one of search information, and the user can select a desired genre from the genre list.

  The store list display field 509 displays a list of store information acquired from the store data providing unit 13 at the position indicated when the store marker 504 is stopped without being dragged. Further, when the moving speed Vs in the state where the store marker 504 is dragged is equal to or lower than the predetermined speed Vth, a list of store information acquired from the store data providing unit 13 is displayed at a position in the middle of the movement. That is, as described above, the personal computer 2 sends a store search request to the store data providing unit 13 of the map site 1 every time the store marker 504 moves on the display screen at a low speed equal to or lower than the predetermined speed Vth by a predetermined distance. The store information of the search result is acquired from the store data providing unit 13, and the list information of the store data is displayed in the store list display field 509. That is, when the movement speed of the store marker 504 is a low speed equal to or lower than the predetermined speed Vth, the store list display field 509 stores the store at the moved position every time the store marker 504 moves by a predetermined distance on the display screen. The list information is displayed sequentially.

  When the predetermined speed Vth is Vth = 0, as described above, every time the movement of the dragged store marker 504 stops, the store list display field 509 stores store list information at the stop position. Will be displayed.

  As described above, in this embodiment, the store data providing unit 13 also includes distance information indicating how far the position of each store obtained as a search result from the center of the area range is a list of store names. Together with the information, it is transmitted to the information display device as information of the search result. Therefore, in this embodiment, as shown in FIG. 13, the distance from the center position indicated by the store marker 504 is displayed together with the store name in each store information of the store list information.

  Furthermore, the history display icon button 510 is an operation button used when displaying the store list information acquired and stored at each position when the store marker 504 is moved by dragging. When detecting that the history display icon button 510 has been clicked by the user, the CPU 201 obtains address data corresponding to each movement position of the store marker stored in the marker movement history storage unit 2111 of the history storage unit 211. read out. Then, as illustrated in FIG. 14, the CPU 201 displays a history list display field 511 instead of the store list display field 509 and displays a list of addresses that have been read. Here, in this example, the address list displays the addresses of the respective movement positions in the order of the address in the following, starting with the address at the most recent position.

  When the user clicks on one address in the address list in the history list display field 511, the CPU 201 uses the position information of the store marker corresponding to the address as a searcher from the store list data storage unit 212. Read the corresponding store list information. Then, instead of the history list display column 511, the CPU 201 displays a store list display column 509 in the same manner as in FIG. 13, and displays the read store list information. That is, a list of stores searched at the selected address position in the movement history is displayed as the store list display field 509. Thereby, the user can display and view the store search result at the position in the middle of movement when the store marker 504 is slowly moved or stopped.

  Next, as described above, after the store marker 504 is dragged and moved and then dropped (drag released) and the store marker 504 is stopped, stores in the area range centered on the stop position The list information is acquired from the store data providing unit 13 and displayed. In this embodiment, in this state, the area range can be changed or the genre can be changed.

  That is, for example, when the radius of the area range is changed from “100 meters” in FIG. 13 to “200 meters” as shown in FIG. 15, the search unit 210 of the personal computer 2 as shown in FIG. Sends a store search request including the changed area range, the specified genre at that time, and the information on the designated position of the store marker 504 to the store data providing unit 13. In response to this search request, the store data providing unit 13 performs a search by expanding the area range, and sends the search result to the personal computer 2. The search unit 210 of the personal computer 2 receives this search result information and transfers it to the display control unit 204 and the movement history storage unit 211. The display control unit 204 and the movement history storage unit 211 process the received search result information in the same manner as described above.

  On the display screen of the display 22 of the personal computer 2, the size of the area range display unit 506 displayed around the indicated position of the store marker 504 in the map image display field 501 is doubled. The contents of the store list display field 509 are changed.

  As shown in FIG. 15, a base mark 512 indicating the location of the searched store is displayed in the area range display unit 506, and when one of the base marks 512 is clicked, the store list display field 509 is displayed. The corresponding store name column in the store list may be highlighted.

  Even when the user changes the genre of the store in the genre input field 508, the personal computer 2 similarly issues a store search request using the changed genre to the store data acquisition unit 13. Send and make a search request. Then, the personal computer 2 receives the search result and executes the above-described processing operation in the display control unit 204 and the movement history storage unit 211.

[Example of Store Search Processing Operation on PC 2]
Next, the flow of the processing operation of the personal computer when executing the store search in the third embodiment described above will be described with reference to the flowcharts of FIGS. The processing of each step described below is performed by the CPU 201 executing according to the program acquired from the map site 1 using the RAM 203 as a work area. That is, the processing example of the following flowchart is a case where the CPU 201 executes the processing functions of the display control unit 204, the reception signal processing unit 207, the transmission signal generation unit 208, and the search unit 210 as software functions.

  First, the CPU 201 determines whether or not an operation instruction to access the map site 1 is given by the user (step S201). If it is determined in this step S201 that an instruction to access the map site 1 has not been issued, the CPU 201 proceeds to another processing routine (step S202), and when that processing routine ends, the process returns to step S201.

  If it is determined in step S201 that an instruction to access the map site 1 has been issued, the CPU 201 displays a service list sent from the map site 1 (step S203). Next, the CPU 201 determines whether or not a map service with store search in the service list is selected (step S204). When a map service other than the map service with store search is selected, the selected service is selected. The processing routine is shifted to (Step S205). In this embodiment, the map service with store search will be described, so the detailed description of step S205 will be omitted.

  When it is determined in step S204 that the map service with store search has been selected, the CPU 201 sends a request for the map service with store search to the map site 1 (step S206). Then, since the map image information on which the store marker 504 and the balloon display 505 are superimposed is sent from the map site 1, the CPU 201 displays a window in which the map image 503 is displayed on the display screen of the display 22. The information is displayed in the column 501 (step S207). At this time, the default radius and genre are displayed in the area range input field 507 and the genre input field 508, and the store list display field 509 has a default centered on the position indicated by the store marker 504. A list of store names searched by area range and genre is displayed. In the balloon display portion 505, the store names listed at the top of the store list display field 509 are displayed.

  Next, the CPU 201 determines whether or not the user has dragged the mouse 23 on the map image 503 (step S208). When it is determined that the drag operation has been performed, the drag operation is performed on the store marker 504. It is determined whether or not it has been made (step S209).

  When it is determined that the drag operation has not been performed on the store marker 504, the CPU 201 determines whether or not the drag operation has been performed (step S210). The map image 503 of 501 is moved in the moved direction (step S211). At this time, as described above, when the map data of the map image 503 to be newly displayed has not yet been acquired, the CPU 201 requests the map data providing unit 11 of the map site 1 to acquire the map data. The map data is acquired.

  Then, the CPU 201 determines whether or not the drag is released (step S212). When it is determined that the drag is released, the process returns to step S208, and the processes after step S208 are repeated. If it is determined in step S210 that the drag has not been released, the CPU 201 returns the process to step S210 and repeats the processes after step S210.

  If it is determined in step S210 that the drag has not been moved, the CPU 201 advances the process to step S212 to determine whether the drag has been released. And the process after this step S212 is repeated.

  Next, when it is determined in step S209 that the drag operation has been performed on the store marker 504, the CPU 201 determines whether or not the drag is released (step S221 in FIG. 17). When it is determined in step S221 that the drag has not been released, the CPU 201 starts detecting and monitoring the moving speed Vs of the dragged store marker 504 on the display screen (step S222). Then, it is determined whether or not the position of the dragged store marker 504 has changed by a predetermined distance or more (a predetermined length or more on the display screen) (step S223).

  When it is determined in step S223 that the position of the store marker 504 has not changed by a predetermined length or more on the display screen, the CPU 201 returns to the processing step S221 and repeats the processing after step S221.

  When it is determined in step S223 that the position of the store marker 504 has changed by a predetermined length or more on the display screen, the CPU 201 determines whether or not the moving speed Vs of the store marker 504 is equal to or lower than a predetermined speed Vth. A determination is made (step S224). If it is determined in step S224 that the moving speed Vs of the store marker 504 is not lower than the predetermined speed Vth, but is higher than the predetermined speed Vth, the CPU 201 returns the process to step S221.

  If it is determined in step S224 that the movement speed Vs of the store marker 504 is equal to or lower than a predetermined speed Vth, the CPU 201 uses the function of the search unit 210 to correspond to the position after the store marker 504 has moved. Information on latitude and longitude, area range information (radius value), and store genre information are acquired from the display image correspondence search information storage unit 209. Then, a store search request is sent to the store data providing unit 13 (server) using the acquired latitude, longitude, area range, and genre information as search information (step S225).

  Then, the CPU 201 acquires store data and address data as search results sent from the store data providing unit 13 (step S226). Then, the CPU 201 additionally stores the acquired address data in the marker movement history storage unit 2111 of the movement history storage unit 211 in association with the latitude and longitude corresponding to the position of the store marker 504, and stores the acquired store data. Then, it is additionally stored in the store list data storage unit 2112 of the movement history storage unit 211 (step S227).

  Then, the store list information based on the received store information is displayed in the store list display field 509 of the display screen of the display 22, and in this example, the first store name of the store list is a balloon attached to the store marker 504. The information is displayed on the display unit 505 (step S228). And CPU201 returns a process to step S221, and repeats the process after this step S221.

  When it is determined in step S221 that the drag has been released, the CPU 201 determines whether or not the store marker 504 has moved from the dragged position (step S231 in FIG. 18), and determines that it has not moved. If so, the process returns to step S208, and the processes after step S208 are repeated.

  When it is determined in step S231 that the store marker 504 has moved from the dragged position, the CPU 201 detects latitude and longitude information corresponding to the position after the store marker 504 has moved, and region range information ( (Value of radius) and store genre information are acquired from the display image correspondence search information storage unit 209, and the store search request is sent to the store data providing unit 13 as the search information (step S232). ).

  And CPU201 acquires store data and address data as a search result sent from store data offer part 13 (Step S233). Then, the CPU 201 additionally stores the acquired address data in the marker movement history storage unit 2111 of the movement history storage unit 211 in association with the latitude and longitude corresponding to the position of the store marker 504, and stores the acquired store data. Then, it is additionally stored in the store list data storage unit 2112 of the movement history storage unit 211 (step S234).

  Then, store list information based on the received store information is displayed in the store list display field 509 on the display screen of the display 22, and the head store name of the store list is displayed on the balloon display unit 505 attached to the store marker 504. It is displayed (step S235). Next, the CPU 201 returns the processing to step S208 and repeats the processing after step S208.

  Next, when it is determined in step S208 in FIG. 16 that the user has not dragged the mouse 23, the CPU 201 determines whether or not the radius value of the area range input field 507 has been changed (step S208). S241). If it is determined in step S241 that the radius value of the area range input field 507 has been changed, the CPU 201 uses the area range radius value held in the display image correspondence search information holding unit 209 to input the area range. The radius value specified in the field 507 is changed (step S242).

  Then, the CPU 201 returns the process to step S232, and executes the processes after step S232. That is, the CPU 201 requests a search by sending a store search request with a radius value obtained by changing the area range in the search information to the store data providing unit 13. Then, the search result is received from the store data providing unit 13, the received search result information is stored in the store list data storage unit 2112 of the movement history storage unit 211, and the display 22 is displayed. To reflect the search results.

  If it is determined in step S241 that the radius value in the area range input field 507 has not been changed, the CPU 201 determines whether or not the genre in the genre input field 508 has been changed (step S243). When it is determined in step S243 that the genre has been changed, the CPU 201 changes the genre information held in the display image correspondence search information holding unit 209 to the one specified in the genre input field 508 ( Step S244).

  Then, the CPU 201 returns the process to step S232, and executes the processes after step S232. That is, the CPU 201 requests a search by sending a store search request in which the genre is changed among the search information to the store data providing unit 13. Then, the search result is received from the store data providing unit 13, the received search result information is stored in the store list data storage unit 2112 of the movement history storage unit 211, and the display 22 is displayed. To reflect the search results.

  If it is determined in step S243 that the genre in the genre input field 508 has not been changed, the CPU 201 selects one of the store names in the store list display field 509 by clicking on the store name. It is determined whether or not it has been done (step S245). If it is determined in step S245 that one store name in the store list has been selected, the CPU 201 sends a search request including the store ID of the selected store name to the store data providing unit 13 and selects the selected store name. The detailed information of the store with the specified store name is requested (step S246).

  Upon receiving this search request, the store data providing unit 13 sends detailed information (address, provided product, contents of provided service, etc.) stored corresponding to the store ID to the personal computer 2 as a search result. Therefore, the CPU 201 receives this detailed information, generates a display image based on the detailed information, and displays it on the display screen of the display 22 (step S247). The display image of the detailed information is displayed in the map image display field 501 instead of the map image, for example. Of course, the detailed information may include a map around the store.

  Next, the CPU 201 determines whether or not the “return icon” displayed on the display screen of the display 22 has been clicked (step S248). If it is determined that the “return icon” has been clicked, the process is stepped. Return to S235. That is, the display image on the display 22 is returned to the state in which the map image in which the store marker 504 is superimposed on the map image display field 501 is displayed.

  If it is determined that the “return icon” has not been clicked, the CPU 201 determines whether or not an end operation has been performed (step S249). If it is determined that no end operation has been performed, the process proceeds to step S248. Return to. If it is determined in step S248 that the termination operation has been performed, the CPU 201 disconnects from the map site 1 and performs termination processing (step S250), and the processing routine is terminated.

  If it is determined in step S245 that one store name in the store list has not been selected, the CPU 201 determines whether or not the history display icon button 510 has been clicked (step S251).

  When it is determined in step S251 that the history display icon button 510 has been clicked, the CPU 201 stores the store marker when the store search request is sent from the marker movement history storage unit 2111 of the movement history storage unit 211 to the store data providing unit 13. Address data at the position 504 is read. Then, instead of the store list display column 509, the CPU 201 displays a history list display column 511 including a list of read addresses as shown in FIG. 14 (step S252).

  Next, the CPU 201 determines whether or not one history (address) in the history list in the history list display field 511 has been selected (step S261 in FIG. 20), and one history (address) is selected and operated. When the determination is made, the store marker 504 is moved so as to indicate the selected address value, and the store list data acquired from the store data providing unit 13 at the address location is read from the store list data storage unit 2112 to store the store list. The information is displayed in the display field 509 (step S262). Thereafter, the CPU 201 returns the process to step S208 and repeats the processes after step S208.

  If it is determined in step S261 that one history (address) in the history list has not been selected, the CPU 201 returns the process to step S248, determines whether or not the “return icon” has been clicked, and “ When the “return icon” is clicked, the process returns to step S235 to return the display image on the display 22 to a state in which a map image on which the store marker 504 is superimposed is displayed.

  If it is determined in step S251 that the history icon button 510 has not been clicked, the CPU 201 determines whether an operation for starting another process has been performed (step S271 in FIG. 21), and starts the other process. When it is determined that an operation to be performed has been performed, the process that has been started is executed (step S272). Thereafter, the CPU 201 returns the process to step S208 and repeats the processes after step S208.

  When it is determined in step S271 that an operation for starting another process has not been performed, the CPU 201 determines whether or not an end operation has been performed (step S273). When it is determined that an end operation has not been performed, The process returns to step S208, and the processes after step S208 are repeated. If it is determined in step S273 that the termination operation has been performed, the CPU 201 disconnects from the map site 1 and performs termination processing (step S274), and the processing routine is terminated.

[Effect of the third embodiment]
As described above, according to the information display device of the third embodiment, only by superimposing the store marker on the map image, it is within a predetermined region range centered on the position where the store marker is placed. Since the list of stores of the specified genre existing in is displayed on the display, an operation such as clicking the position with the mouse is not necessary. When the store marker is moved, the list of stores in each area range being moved can be moved while being displayed, which is very convenient when searching for stores.

  In addition, when the store marker is moved, the position where the store marker has passed is displayed as a list of addresses as a history, and by selecting one address in the list, the map is moved while moving the store marker. It is easy to obtain a list of stores in the area range centered on the address obtained from the site, which is convenient.

  In the above-described third embodiment, the moving speed of the dragged store marker is monitored, and whether or not the search during movement is controlled according to the moving speed is controlled. It is possible to execute a search according to the intention of the user efficiently. That is, when the user drags and moves the marker and only wants the search result at the drop position, the moving speed of the marker may be set to a predetermined speed or higher. Conversely, by dragging the marker to move it relatively slowly or stopping it, the user can move the marker to the drag release position while searching for information on the movement path. The function of determining whether or not to execute a search during movement according to the moving speed of the dragged marker is not limited to the third embodiment, but is the same as the first embodiment and the second embodiment described above. Is also applicable.

[Modification of Third Embodiment]
In the above-described third embodiment, when the dragged store marker is moved, an address corresponding to the position indicated by the store marker 504 when the store search request is sent to the store data providing unit 13 is displayed as the marker movement history. I kept it as information. However, acquisition of an address corresponding to the position indicated by the store marker 504 is not essential, and a number in the order of movement is assigned to each movement position, and that number is stored in the store list data storage unit 2112. Each time the display icon button 510 is operated, a list of stores at each movement position may be displayed one by one. In that case, the store marker 504 is displayed on the map position indicating the movement position where the store list is displayed together with the balloon display unit 505 and the area display unit 506. In this case, the marker movement history storage unit 2111 need not be provided.

  Also in the above-described third embodiment, when the dragged store marker 504 moves by a predetermined distance on the screen, the store marker 504 is moved, and store data is acquired for the moved position. I did it. However, as in the first embodiment described above, when the store marker 504 is dragged, store data may be acquired at regular intervals until the drag is released. In this case, as in the case of the first embodiment described above, the movement history storage unit newly acquires the search results newly acquired at that time and the search results acquired earlier than that (movement history storage unit). The search result at the time is stored if the two are different from each other.

  In the above description of the third embodiment, the moving speed of the dragged marker is constantly detected and monitored. However, every time the dragged marker moves a predetermined distance or every fixed time. When determining whether or not to execute the search, the speed of the marker at that time may be detected and used for the determination.

  Also in this third embodiment, when the mobile phone terminal 3 is an information display device, an operation of pointing the store marker displayed on the display screen 31 with a finger and moving it as it is, By performing a drag operation on the touch panel 32, a processing operation similar to that described in the above embodiment can be realized.

  In the above description of the third embodiment, only one store marker is used. However, a plurality of store markers may be displayed simultaneously on one map image. In that case, the store list may be divided into a plurality of items and displayed in correspondence with each store marker. Moreover, you may enable it to select the area | region range and genre to search with these several shop markers separately, respectively. Furthermore, you may make it prepare the some shop marker which allocated each of the specific genre beforehand.

  In the above-described embodiment, the balloon display unit 505 attached to the store marker 504 may display the address of the location when the store search request is sent to the map site during movement.

  Further, in the third embodiment described above, a store existing in the area range is set as a search target, but the search target searched in the area range is not limited to the store. For example, a library, a government office, a public facility such as a public hall, a tourist spot, or the like within the area can be searched.

  In addition, the search target is not limited to the thing existing in the area range centered on the marker position, but is information related to the area range, for example, information issued by the municipality of the place. Also good. This is also the case when only one point is indicated, such as an address marker. When Mt. Fuji and Sky Tree can be seen from the place or area range, the map site uses this as a search result as an information display device. You may make it return to.

  In the third embodiment described above, the region range centered on the position indicated by the marker 504 is circular, but the region is not limited to a circular region. For example, as shown in FIG. 22, as a method of defining the region range, walking time with the position pointed to by the marker 504 as a reference point can be used. In this case, a linear distance from the reference position by the walking route Will be different. Therefore, as in the example of FIG. 22, when walking time is used as a method of defining the region range, the region range centered on the position indicated by the marker 504 is the walking time on the map. Since it is represented by a line segment area connecting points converted into distances, the shape thereof becomes a shape according to the walking route on the map as shown in FIG.

  Further, an administrative area such as a municipal boundary may be used for the area range centered on the position indicated by the marker 504. In addition, the region range centered on the position indicated by the marker 504 can be various shapes.

  In the third embodiment described above, the area range is fixed to the size set by the user. However, while moving by dragging the marker, the area range is set to a relatively narrow area, and the movement of the marker is stopped. Then, when dropping (releasing the drag), the area range may be automatically expanded.

  In the description of the third embodiment described above, the address data and the store data of the search result acquired at the position after the movement are written in the movement history storage unit 211 every time the distance moves by a predetermined distance or more. However, in the case of the first embodiment described above, when the address data and store data of the search result acquired at the position after movement are the same as the address data and store data of the search result acquired before that, Similarly to the above, it goes without saying that the movement history storage unit 211 may not write the acquired data.

  In the third embodiment described above, the address data displayed in the history list display field 511 is acquired from the store data providing unit 13 in addition to the store information when a store search request is made. However, only information on the position (latitude, longitude) of the store marker 504 is stored in the marker movement history storage unit 2111. When the history display icon button 510 is clicked, the store marker 504 stores the information of the store marker 504. A search request for address data using the position information as search information may be sent to the store data providing unit 13 to acquire corresponding address data.

[Other Embodiments or Modifications]
The information display device according to the above-described embodiment is an example in which a search is executed by accessing a server. However, when the information display device itself has a function of executing a search based on the database function of the server and the information for search, the same configuration as the above-described system may be realized only by the information display device. it can.

  In the description of the above-described embodiment, the balloon display unit is attached to the marker to move both together. However, only the marker is moved, and the corresponding address, store name, etc. are displayed on the map screen. You may make it display fixedly in a specific position. Further, the balloon display unit may be omitted.
