Description
Display control device, display control method, and program 【0001】 The present invention relates to a display control device, a display control method, and a program. 【0002】 In recent years, a display control device that causes a display unit to display POI (Point of Interest) information, which is information regarding a specific location in which a user is interested, has become widespread. The display control device causes the display unit to display, for example, a map in which POI symbols indicating the positions of facilities, stores, etc. existing around the current position of the user are superimposed. Generally, when there are a large number of POI symbols on a map, in order to reduce the number of POI symbols displayed within the screen, for example, the user designates a map area to be displayed and enlarges the display of the map. 【0003】 For example, as this type of technology, when displaying POI symbols on a map, a dividing line that divides map information into a plurality of parts and identification information for identifying each divided map area are displayed, and a technology for enlarging and displaying a map area corresponding to the identification information input by voice from the user has been proposed (see, for example, Patent Document 1). 【0004】 Japanese Unexamined Patent Application Publication No. 2004-69426 【0005】 However, in the technology described in Patent Document 1 mentioned above, since only the map area corresponding to the identification information input by voice from the user is enlarged and displayed, for example, when it is desired to display map information including POI symbols existing at positions straddling the dividing line, one example of the problem is that the user is confused about which map area should be designated. 【0006】 The present invention has been made in view of the problems cited as an example above, and a main object thereof is to provide a display control device, a display control method, and a program that can easily display map information including POI symbols desired by the user. 【0007】To solve the above problems, the invention described in claim 1 is a display control device comprising: a reception unit for receiving input from a user; and a display control unit for displaying a selection image on a display unit, which includes a map on which POI symbols and dividing lines are superimposed, and identification information for identifying each of the map areas divided by the dividing lines, wherein when the reception unit receives input for selecting one of the identification pieces of information, the display control unit displays a new selection image on the display unit, which includes a map corresponding to a target area composed of a selection area which is the map area corresponding to the one identification piece of information, and a predetermined range from a plurality of map areas adjacent to the selection area. 【0008】 To solve the above problems, the invention described in claim 7 is a display control method for a display control device comprising a reception unit and a display control unit, characterized in that the reception unit includes a first step of receiving input from a user; the display control unit causes the display control unit to display a selection image on the display unit that includes a map on which POI symbols and dividing lines are superimposed, and identification information that identifies each of the map areas divided by the dividing lines; and the display control unit, when it receives input to select one of the identification pieces of information in the first step, causes the display control unit to display a new selection image on the display unit that includes a map corresponding to a target area composed of a selection area which is the map area corresponding to the identification piece of information, and a predetermined range from a plurality of map areas adjacent to the selection area. 【0009】To solve the above problems, the invention described in claim 8 is a program for causing a computer to execute a display control method for a display control device, characterized in that the computer is caused to execute a first step of receiving input from a user; a second step of causing a display unit to display a selection image including a map on which POI symbols and dividing lines are superimposed, and identification information that identifies each of the map areas divided by the dividing lines; and a third step of causing the display unit to display a new selection image when the input of selecting one of the identification information is received in the first step, the selection image including a map corresponding to a target area composed of a selection area which is the map area corresponding to the one identification information, and a predetermined range from a plurality of map areas adjacent to the selection area. 【0010】 This is a diagram showing the configuration of a display control device according to the first embodiment of the present invention.

This is a diagram showing the processing flow of the display control device according to the second embodiment of the present invention. 【0011】The display control device according to this embodiment includes a reception unit that receives input from a user, and a display control unit that displays a selection image on the display unit, which includes a map on which POI symbols and dividing lines are superimposed, and identification information that identifies each of the map areas divided by the dividing lines. When the reception unit receives input to select one piece of identification information, the display control unit displays a new selection image on the display unit, which includes a map corresponding to a target area consisting of a selection area that is the map area corresponding to the selected piece of identification information, and a predetermined range from among a plurality of map areas adjacent to the selected area. In other words, when the display control device displays a new selection image on the display unit that corresponds to a selection area selected by the user, it displays a map of the target area on the display unit that includes the selection area selected by the user and a part of the map area adjacent to the selected area. As a result, the display control device can easily display map information including the POI symbol desired by the user, even if the POI symbol desired by the user is located across a dividing line. When a user wants to display a map that includes a POI symbol located across a dividing line, they can do so by specifying one of the map areas that the POI symbol crosses. This allows the user to easily select the area they want to view. 【0012】The display control device according to this embodiment includes a detection unit that detects the overlap between a dividing line that separates a selected area and a POI symbol. When the display control unit detects an overlap between the dividing line that separates a selected area and a POI symbol, it displays a new selection image on the display unit that includes a map corresponding to the target area. When no overlap is detected between the dividing line that separates a selected area and a POI symbol, the display control unit displays a new selection image on the display unit that includes a map corresponding to the selected area. When the display control device displays a map corresponding to a selected area selected by the user, it determines whether or not there is an overlap between the dividing line that separates the selected area and the POI symbol. In other words, if the display control device determines that there is no overlap between the dividing line that separates the selected area selected by the user and the POI symbol, it does not need to display a map area adjacent to the selected area, and therefore displays a new selection image on the display unit that includes a map corresponding to the selected area. This allows the display control device to display map information including the POI symbol desired by the user in a larger size on the display unit. 【0013】 In this embodiment, the display control unit of the display control device displays a selection image on the display unit that includes POI symbols with assigned identification numbers if the number of POI symbols superimposed on the map displayed on the display unit is less than or equal to a predetermined number. For example, if the number of POI symbols present in the selection image to be displayed is five or less, the display control unit displays POI symbols to which identification numbers such as serial numbers have been assigned. This allows the user to easily specify the POI symbols from which they want to obtain POI information, even while driving, for example, by speaking an identification number. 【0014】 In this embodiment, the display control unit of the display control device displays a selection image containing POI information corresponding to a POI symbol on the display unit when there is only one POI symbol superimposed on the map displayed on the display unit. This allows the user to obtain POI information without having to perform operations such as inputting an identification number. 【0015】The display unit of the display control device according to this embodiment is installed on a motorcycle. The reception unit of the display control device according to this embodiment receives voice input from the user. Generally, when a user is riding a motorcycle, they cannot perform detailed operations such as selecting POI symbols or selecting map areas to display by touching the screen. Therefore, it is necessary to perform operations such as selecting display areas or POI symbols using the user's voice. In other words, the user can specify the POI symbol from which they want to obtain POI information by speaking an identification number. This allows the user to easily obtain information about the desired POI even while riding a motorcycle. 【0016】 <Examples> Hereinafter, examples of the present invention will be described with reference to Figures 1 to 15. 【0017】 <First Embodiment> The display control device 10 according to this embodiment will be described with reference to Figures 1 to 10. In this embodiment, the display control device 10 controls the image to be displayed on a display unit installed in a vehicle such as a bicycle, motorcycle, or four-wheeled vehicle. The following description will illustrate the case in which the display control device 10 controls the image to be displayed on a display unit installed in a motorcycle. 【0018】 As shown in Figure 1, in this embodiment, the display control device 10 is connected, for example, to the microphone 100 and the display unit 200. 【0019】 In this embodiment, the microphone 100 is, for example, a microphone built into a helmet worn by a user driving a motorcycle, which acquires the user's spoken voice and outputs the spoken voice to the display control device 10, for example, via short-range wireless communication. 【0020】In this embodiment, the display unit 200 is, for example, a display panel such as a liquid crystal panel or an organic EL (Electro-Luminescence) panel, and displays an image input from the display control device 10. In this embodiment, the display unit 200 displays, for example, a map on which POI symbols indicating the location of POIs are superimposed. Details of the image that the display control device 10 displays on the display unit 200 will be described later. 【0021】 <Configuration of the display control device 10> As shown in Figure 2, the display control device 10 is configured to include a reception unit 11, a storage unit 12, a display control unit 13, and a detection unit 14. 【0022】 The reception unit 11 receives input from the user. In this embodiment, the reception unit 11 analyzes the user's speech picked up by the microphone 100, for example, and recognizes the content of the speech. In this embodiment, if the reception unit 11 detects an operation instruction for an image to be displayed on the display unit 200 from the recognized speech content, it outputs the detection result to the display control unit 13, which will be described later. Specifically, in this embodiment, if the reception unit 11 detects an operation instruction such as "display the ATM (Automated Teller Machine) symbol on the map" from the user's speech content, it outputs the detection result to the display control unit 13, which will be described later. In this embodiment, if the reception unit 11 detects identification information from the user's speech content, for example, it outputs the detected identification information to the display control unit 13, which will be described later. In this embodiment, if the reception unit 11 detects an identification number from the user's speech content, for example, it outputs the detected identification number to the display control unit 13, which will be described later. The above-mentioned identification information and identification number will be described later. 【0023】In this embodiment, the storage unit 12 pre-stores, for example, the control program for the display control device 10. In this embodiment, the storage unit 12 pre-stores, for example, map information. In this embodiment, the storage unit 12 pre-stores, for example, POI information. Examples of the POI information mentioned above include, for example, genre information, location information (e.g., address, latitude and longitude information, etc.), and detailed information (e.g., telephone number, business hours, recommended information, etc.). Examples of the genre information mentioned above include, for example, restaurants, department stores, ATMs, convenience stores, gas stations, tourist spots, theme parks, etc. The map information and POI information stored in the storage unit 12 are updated as needed. 【0024】 In this embodiment, the display control unit 13 controls the overall processing of the display control device 10 according to a control program stored in the storage unit 12, for example. In this embodiment, the display control unit 13 generates an image to be displayed on the display unit 200 based on the detection result input from the reception unit 11, and displays it on the display unit 200. In this embodiment, for example, when the reception unit 11 inputs information about POIs that the user wants to display (for example, an operation to display the location of ATMs within 5 km of the current location on a map), the display control unit 13 acquires the user's current location information from a mobile terminal carried by the user (not shown) or a current location positioning unit (not shown) provided in the display control device 10, for example, and acquires POI information (for example, ATMs) and map information from the storage unit 12. 【0025】The display control unit 13 causes the display unit 200 to display a selection image that includes a map with POI symbols and dividing lines superimposed on it, and identification information that identifies each of the map areas divided by the dividing lines. As shown in Figure 3, in this embodiment, for example, when the reception unit 11 inputs a detection result indicating that it wants to display information about an ATM, the display control unit 13 displays a map (for example, a road 210, etc.) on the display unit 200 with POI symbols 220 indicating the location of the ATM and dividing lines superimposed on it, based on the POI information about the ATM obtained from the storage unit 12, map information, and the user's current location information. In this embodiment, the display control unit 13 causes the display unit 200 to display the user's current location mark 230 superimposed on the map described above, based on the user's current location information obtained from a current location positioning unit (not shown). In this embodiment, the display control unit 13 causes the display unit 200 to display identification information that identifies each of the map areas divided by the dividing lines, for example, so as not to overlap with the map display described above. 【0026】 The division lines and identification information described above will be explained using Figure 4. As shown in Figure 4, in this embodiment, the display control unit 13 superimposes five division lines each in the vertical and horizontal directions on the map to be displayed on the display unit 200, thereby dividing the map into 16 map areas. The number of division lines is not limited to five, as long as the map to be displayed can be divided into multiple map areas. Also, the number of division lines in the vertical and horizontal directions may be different. In this embodiment, when the display control unit 13 displays the map described above on the display unit 200, it also displays identification information that identifies each of the 16 map areas. In this embodiment, the display control unit 13 displays identification information A to D indicating the map areas divided by the vertical division lines, and identification information 1 to 4 indicating the map areas divided by the horizontal division lines, in a position that does not overlap with the map display. In this embodiment, for example, if the user wants to display the map corresponding to the map area hatched with diagonal lines in Figure 4, they say "B-2". 【0027】When the reception unit 11 receives input to select a single piece of identification information, the display control unit 13 displays a new selection image on the display unit 200, which includes a map corresponding to the target area, consisting of a selection area that is a map area corresponding to the single piece of identification information, and a predetermined range from among a plurality of map areas adjacent to the selection area. In this embodiment, for example, if the reception unit 11 inputs a detection result indicating that "B-2" has been detected, the display control unit 13 determines the map area indicated by "B-2" as the selection area. In this embodiment, for example, if the selection area is determined to be "B-2", the display control unit 13 determines the target area, which consists of the selection area "B-2" and a predetermined range from among the map areas adjacent to the selection area "B-2". As shown in Figure 5, in this embodiment, for example, if the selected area is "B2", the display control unit 13 determines the target area (the area enclosed by the dotted line) to include the selected area "B2" and a predetermined range from the map areas "A1", "A2", "A3", "B1", "B3", "C1", "C2", and "C3" that are adjacent to the selected area "B2". 【0028】 An example of how the display control unit 13 determines the target area will be explained using Figure 6. In this embodiment, for example, if the selected area is "B2", the display control unit 13 determines the target area by enlarging the rectangle representing the selected area "B2" at the intersection of its diagonals Z, with the same aspect ratio in both width and height. In this embodiment, for example, the display control unit 13 determines the target area such that the ratio of the length a of the diagonal of the rectangle representing the selected area "B2" to the length b of the diagonal of the rectangle representing the target area is a predetermined value (for example, b / a = 1.2). 【0029】In this embodiment, the display control unit 13, for example, if it detects an overlap between a dividing line separating the selected area and a POI symbol 220, displays a new selection image on the display unit 200, including a map corresponding to the target area. If it does not detect an overlap between a dividing line separating the selected area and a POI symbol 220, it displays a new selection image on the display unit 200, including a map corresponding to the selected area. In this embodiment, for example, if the reception unit 11 receives input to select one piece of identification information and the selected area is determined, the display control unit 13, if it obtains a detection result from the detection unit 14 (described later) indicating an overlap between a dividing line separating the user-selected selected area (for example, "B-2" in Figure 5) and a POI symbol 220, obtains the map information corresponding to the target area from the storage unit 12 and displays a new selection image on the display unit 200, including the map corresponding to the target area, the POI symbol 220, the dividing line, and the identification information. In this embodiment, for example, when the reception unit 11 receives input to select one piece of identification information and a selection area is determined, the display control unit 13, if it obtains a detection result from the detection unit 14 (described later) indicating that there is no overlap between the dividing line separating the user-selected selection area (for example, "C-3" in Figure 5) and the POI symbol 220, obtains map information corresponding to the user-selected selection area ("C-3") from the storage unit 12, and displays a new selection image on the display unit 200 that includes the map corresponding to the selection area, the POI symbol 220, the dividing line, and the identification information. In this way, if the number of POI symbols 220 present on the map shown in the selection image is large and it is difficult for the user to select the desired POI symbol 220, the user can repeatedly input voice information for the identification information of the map area where the desired POI symbol exists in the selection image, thereby enlarging the map and reducing the number of POI symbols 220 present on the map. 【0030】If the number of POI symbols 220 superimposed on the map displayed on the display unit 200 is less than or equal to a predetermined number, the display control unit 13 causes the display unit 200 to display a selection image including the POI symbols 220 to which identification numbers have been assigned. In this embodiment, for example, if the number of POI symbols 220 present in the selection image to be displayed on the display unit 200 is less than or equal to a predetermined number (for example, 5 or fewer), the display control unit 13 causes the display unit 200 to display a map superimposed with POI symbols 220 to which identification numbers have been assigned, as shown in Figure 7. In this embodiment, for example, if the reception unit 11 inputs a detection result indicating that the utterance "number 2" has been detected, the display control unit 13 obtains POI information corresponding to the POI symbol 220 to which identification number 2 has been assigned from the storage unit 12 and displays it on the display unit 200. 【0031】If there is only one POI symbol 220 superimposed on the map displayed on the display unit 200, the display control unit 13 displays a selection image containing POI information corresponding to that POI symbol 220 on the display unit 200. In this embodiment, for example, if there is only one POI symbol 220 in the selection image to be displayed on the display unit 200, the display control unit 13 displays POI information (for example, name, location information, business hours, etc.) as shown in Figure 8 on the display unit 200. In this embodiment, for example, if the reception unit 11 inputs a detection result indicating that the utterance "I'm going here" has been detected, the display control unit 13 calculates the route from the user's current location to the location of the POI symbol displaying the POI information, and displays the guidance route, etc., on the display unit 200. In this embodiment, for example, if the reception unit 11 inputs a detection result indicating that the utterance "return to map" has been detected, the display control unit 13 will display the selection image that was previously displayed on the display unit 200 again on the display unit 200. Furthermore, even if there are multiple POI symbols 220 superimposed on the map displayed on the display unit 200, if there is only one POI symbol 220 in the selection area selected by the user via voice input, and the overlap between the dividing line separating the selection area and the other POI symbols 220 is not detected by the detection unit 14 (described later) (for example, if the user selects "A3" in the selection image shown in Figure 5), the display control unit 13 may display the POI information shown in Figure 8 on the display unit 200 without enlarging the selection area. 【0032】When the reception unit 11 receives an input indicating the selection of a single identification piece of information, and the selection area is determined, the detection unit 14 detects the overlap between the dividing line separating the selection area and the POI symbol 220. In this embodiment, for example, the detection unit 14 can determine whether there is a POI symbol 220 in the selection image that overlaps with the dividing line separating the selection area selected by the user, based on the map location information of the dividing line separating the selection area, the location information of POIs existing around the dividing line, and the scale information of the map displayed in the selection image. Alternatively, the detection unit 14 may obtain the currently displayed selection image and information of the selection area from the display control unit 13, and perform a geometric analysis on the dividing line separating the selection area to determine whether there is a POI symbol 220 that overlaps with the dividing line separating the selection area selected by the user. In this embodiment, for example, the detection unit 14 outputs the detection result to the display control unit 13. 【0033】 <Processing Flow of Display Control Unit 13> The processing flow of the display control unit 13 of the display control device 10 will be explained using Figures 9 and 10. This processing flow is started, for example, when the reception unit 11 receives an operation from the user to specify a POI to be the target of detailed information display from the POI symbol on the map, and is repeatedly executed until a predetermined termination condition is met, such as when the detailed information of the specified POI is displayed or when the operation is canceled midway. 【0034】 As shown in Figure 9, the display control unit 13 causes the display unit 200 to display a selection image that includes a map, dividing lines, identification information, and POI symbols 220 (step S110). 【0035】 The display control unit 13 determines whether or not the reception unit 11 has received the input of identification information (step S120). If the display control unit 13 determines that the reception unit 11 has not received the input of identification information (NO in step S120), it returns to the standby state. If the display control unit 13 determines that the reception unit 11 has received the input of identification information (YES in step S120), it moves the process to step S130. 【0036】 If the display control unit 13 determines that the reception unit 11 has received the input of identification information (YES in step S120), it obtains the detection result from the detection unit 14 regarding whether or not there is an overlap between the dividing line that separates the selection area selected by the user and the POI symbol 220 (step S130), and proceeds to step S140. 【0037】 The display control unit 13 determines from the detection unit 14 whether it has obtained a detection result indicating that there is an overlap between the dividing line that separates the selection area selected by the user and the POI symbol 220 (step S140). If the display control unit 13 determines from the detection unit 14 that there is an overlap between the dividing line that separates the selection area selected by the user and the POI symbol 220 (YES in step S140), it proceeds to step S150. If the display control unit 13 determines from the detection unit 14 that there is no overlap between the dividing line that separates the selection area selected by the user and the POI symbol 220 (NO in step S140), it proceeds to step S160. 【0038】 If the display control unit 13 determines from the detection unit 14 that there is an overlap between the dividing line separating the selection area selected by the user and the POI symbol 220 (YES in step S140), it obtains map information corresponding to the target area, which includes the selection area selected by the user and a part of the map area adjacent to the selection area, from the storage unit 12 (step S150), and proceeds to step S170 in Figure 10. 【0039】 If the display control unit 13 determines from the detection unit 14 that there is no overlap between the dividing line that separates the selection area selected by the user and the POI symbol 220 (NO in step S140), it obtains map information corresponding to the selected area from the storage unit 12 (step S160) and proceeds to step S170 in Figure 10. 【0040】As shown in Figure 10, the display control unit 13 determines whether the number of POI symbols 220 superimposed on the map to be displayed is less than or equal to a predetermined number (step S170). If the display control unit 13 determines that the number of POI symbols 220 superimposed on the map to be displayed is not less than or equal to the predetermined number ("NO" in step S170), it displays a new selection image on the display unit 200 (step S180) and terminates the process. If the display control unit 13 determines that the number of POI symbols 220 superimposed on the map to be displayed is less than or equal to the predetermined number ("YES" in step S170), it proceeds to step S190. 【0041】 The display control unit 13 determines whether or not there is one POI symbol 220 superimposed on the map to be displayed (step S190). If the display control unit 13 determines that there is more than one POI symbol 220 superimposed on the map to be displayed ("NO" in step S190), it displays an image containing the POI symbol 220 with an assigned identification number on the display unit 200 (step S200) and terminates the process. If the display control unit 13 determines that there is one POI symbol 220 superimposed on the map to be displayed ("YES" in step S190), it displays an image containing POI information on the display unit 200 (step S210) and terminates the process. 【0042】As described above, the display control device 10 according to this embodiment includes a reception unit 11 that receives input from a user, and a display control unit 13 that displays a selection image on the display unit 200 that includes a map with POI symbols 220 and dividing lines superimposed on it, and identification information that identifies each of the map areas divided by the dividing lines. When the reception unit 11 receives input to select one piece of identification information, the display control unit 13 displays a new selection image on the display unit 200 that includes a map corresponding to a target area, which is a selected area that corresponds to the selected area of identification information, and a predetermined range from a plurality of map areas adjacent to the selected area. In other words, when the display control device 10 displays a new selection image on the display unit 200 that corresponds to a selected area selected by the user, it displays a map of the target area on the display unit 200 that includes the selected area selected by the user and a part of the map areas adjacent to the selected area. As a result, the display control device 10 can easily display map information including the POI symbol 220 desired by the user, even if the POI symbol 220 is located across a dividing line. When a user wants to display a map that includes a POI symbol 220 located across a dividing line, they can display the map information including the POI symbol 220 by specifying one of the map areas that the POI symbol crosses. This allows the user to specify a selection area without hesitation. For example, without having to scrutinize the map image to determine which area of the divided map area the desired POI is located in, the user can specify one of the map areas that the POI symbol 220 of the desired POI crosses, and obtain a new selection image with an enlarged map area including the POI symbol 220. 【0043】The display control device 10 according to this embodiment includes a detection unit 14 that detects an overlap between a dividing line that divides a selection area and a POI symbol 220. When the display control unit 13 detects an overlap between the dividing line that divides the selection area and the POI symbol 220, the display control unit 13 causes the display unit 200 to display a new selection image including a map corresponding to the target area. When no overlap is detected between the dividing line that divides the selection area and the POI symbol 220, the display control unit 13 causes the display unit 200 to display a new selection image including a map corresponding to the selection area. When the display control device 10 displays a map corresponding to the selection area selected by the user, it determines whether there is an overlap between the dividing line that divides the selection area and the POI symbol 220. That is, when the display control device 10 determines that there is no overlap between the dividing line that divides the selection area selected by the user and the POI symbol 220, there is no need to display the map area adjacent to the selected selection area. Therefore, a new selection image including the map corresponding to the selected selection area is displayed on the display unit 200. Thereby, the display control device 10 can display the map information including the POI symbol 220 desired by the user in a more enlarged manner on the display unit 200. 【0044】 When the number of POI symbols 220 superimposed on the map displayed on the display unit 200 is less than or equal to a predetermined number, the display control unit 13 of the display control device 10 according to this embodiment causes the display unit 200 to display a selection image including the POI symbol 220 to which an identification number is assigned. For example, when the number of POI symbols 220 existing in the selection image to be displayed is 5 or less, the display control unit 13 displays the POI symbol 220 to which an identification number such as a serial number is assigned. Thereby, even while driving, the user can easily specify the POI symbol 220 for which POI information is to be acquired, for example, by uttering the identification number. 【0045】When the number of POI symbols 220 superimposed on the map displayed on the display unit 200 in the display control device 10 according to this embodiment is one, the display control unit 13 causes the display unit 200 to display a selection image including the POI information corresponding to the POI symbol 220. Thereby, the user can acquire the POI information without performing an input operation such as inputting an identification number. 【0046】 The display unit 200 displayed by the display control device 10 according to this embodiment is installed on a two-wheeled vehicle. The reception unit 11 of the display control device 10 according to this embodiment receives voice input from the user. Generally, during the operation of a two-wheeled vehicle, the user cannot perform fine operations such as touching the screen to select the POI symbol 220 or select the map area to be displayed. Therefore, for example, it is necessary to perform a selection operation of the POI symbol 220 by the user's spoken voice. That is, the user can specify the POI symbol 220 for which the user wants to acquire the POI information by speaking the identification number. Thereby, the user can easily acquire information regarding the desired POI even during the operation of the two-wheeled vehicle. 【0047】 <Second Embodiment> The display control device 10A according to this embodiment will be described with reference to FIGS. 11 to 15. Components denoted by the same reference numerals as those in the first embodiment have the same functions, and thus detailed descriptions thereof will be omitted. In this embodiment, the display control device 10A controls an image to be displayed on the display unit 200 installed in a vehicle such as a bicycle, a motorcycle, or an automobile. Hereinafter, a case where the display control device 10A controls an image to be displayed on the display unit 200 installed in a motorcycle will be exemplified and described. 【0048】 <Configuration of the Display Control Device 10A> As shown in FIG. 11, the display control device 10A includes a reception unit 11, a storage unit 12, a display control unit 13A, and an extraction unit 15. 【0049】In this embodiment, the display control unit 13A controls the overall processing of the display control device 10A according to a control program stored in the storage unit 12, for example. In this embodiment, the display control unit 13A generates an image to be displayed on the display unit 200 based on the detection result input from the reception unit 11, and displays the image on the display unit 200. In this embodiment, for example, when the reception unit 11 inputs information about POIs that the user wants to display (for example, an operation to display the location of ATMs within 5 km of the current location on a map), the display control unit 13 acquires the user's current location information from a mobile terminal carried by the user (not shown) or a current location positioning unit (not shown) provided in the display control device 10, for example, and acquires POI information (for example, ATMs) and map information from the storage unit 12. 【0050】 The display control unit 13A causes the display unit 200 to display a selection image that includes a map with POI symbols 220 and dividing lines superimposed on it, and identification information that identifies each of the map areas divided by the dividing lines. Note that the dividing lines and identification information of the selection image displayed by the display control unit 13A are the same as those of the selection image displayed by the display control unit 13 described above, so a detailed explanation is omitted. 【0051】In this embodiment, when the reception unit 11 receives input to select a single piece of identification information, the display control unit 13A determines a target area consisting of a selection area, which is a map area corresponding to the single piece of identification information, and a predetermined range from among a plurality of map areas adjacent to the selection area. In this embodiment, when the reception unit 11 receives input indicating that, for example, "B-2" has been detected from the user's utterance, the display control unit 13A determines the map area indicated by "B-2" as the selection area. In this embodiment, when the selection area is determined to be "B-2", the display control unit 13A determines a target area consisting of the selection area "B-2" and a predetermined range from among the map areas adjacent to the selection area "B-2". The method for determining the target area is the same as the method for determining the target area of the display control unit 13 described above, so no explanation is given. In this embodiment, the display control unit 13A outputs, for example, information regarding the determined target area and POI information desired by the user (for example, information regarding ATMs, etc.) to the extraction unit 15. 【0052】The extraction unit 15 will now be described. When the receiving unit 11 receives input to select a single piece of identification information, the extraction unit 15 extracts POI symbols 220 within a target area, which is composed of a selection area, which is a map area corresponding to the single piece of identification information, and a predetermined range from among a plurality of map areas adjacent to the selection area. In this embodiment, for example, when the display control unit 13A inputs information about the target area and POI information desired by the user (for example, information about ATMs, etc.), the extraction unit 15 refers to the map information and POI information stored in the storage unit 12 and determines whether or not a POI desired by the user exists within the target area. In this embodiment, for example, if a POI desired by the user exists within the target area, the extraction unit 15 obtains the location information of the POI from the storage unit 12 and outputs the location information to the display control unit 13A. Here, latitude and longitude information can be exemplified as the location information of the POI. In this embodiment, for example, if the extraction unit 15 does not find a POI desired by the user within the target area, it outputs an extraction result indicating that no POIs exist to the display control unit 13A. 【0053】 The display control unit 13A will be described again. The display control unit 13A displays a new selection image on the display unit 200, which includes a map corresponding to the enlarged display area determined based on the position information of the POI symbols 220 extracted by the extraction unit 15. The display control unit 13A determines the enlarged display area so that it includes all of the POI symbols 220 extracted by the extraction unit 15. In this embodiment, for example, the display control unit 13A determines the enlarged display area, which is the area of the map to be displayed on the display unit 200, based on the position information of the POIs (for example, latitude and longitude information) input from the extraction unit 15. An example of how to determine the enlarged display area will be described below. 【0054】In this embodiment, the display control unit 13A calculates, for example, the average value of the maximum and minimum latitude values (hereinafter referred to as the latitude average) and the average value of the maximum and minimum longitude values (hereinafter referred to as the longitude average) when there are multiple POI location information input from the extraction unit 15. As shown in Figure 12, in this embodiment, the display control unit 13A determines the enlarged display area so that the position X indicated by the latitude average and longitude average is the center of the enlarged display area and all of the POI symbols 220 extracted by the extraction unit 15 are included. In this embodiment, the display control unit 13A limits the scale of the map to be displayed so that, for example, an extremely enlarged map is not displayed on the display unit 200. In this embodiment, the display control unit 13A determines the enlarged display area so that the position (latitude and longitude) of the POI input from the extraction unit 15 is the center of the enlarged display area and a map of a predetermined scale is displayed on the display unit 200. In this embodiment, the display control unit 13A causes the display unit 200 to display a new selection image, including a map corresponding to the determined enlarged display area, as shown in Figure 13. 【0055】 If the number of POI symbols 220 superimposed on the map displayed on the display unit 200 is less than or equal to a predetermined number, the display control unit 13A causes the display unit 200 to display a selection image including the POI symbols 220 to which identification numbers have been assigned. In this embodiment, for example, if the number of POI symbols 220 present in the selection image to be displayed on the display unit 200 is less than or equal to a predetermined number (for example, 5 or fewer), the display control unit 13A causes the display unit 200 to display the POI symbols 220 to which identification numbers have been assigned. In this embodiment, for example, if the reception unit 11 inputs a detection result indicating that the utterance "number 2" has been detected, the display control unit 13A obtains POI information corresponding to the POI symbol 220 to which identification number 2 has been assigned from the storage unit 12 and displays it on the display unit 200. 【0056】If there is one POI symbol 220 superimposed on the map displayed on the display unit 200, the display control unit 13A causes the display unit 200 to display a selection image containing POI information corresponding to the POI symbol 220. In this embodiment, for example, if there is one POI symbol 220 in the selection image to be displayed on the display unit 200, the display control unit 13A causes the display unit 200 to display POI information (for example, name, location information, business hours, etc.) as shown in Figure 8. In this embodiment, for example, when the reception unit 11 receives a detection result indicating that the utterance "Go here" has been detected, the display control unit 13A calculates the route from the user's current location to the location of the POI symbol displaying POI information, and displays the guidance route, etc., on the display unit 200. In this embodiment, for example, when the reception unit 11 receives a detection result indicating that the utterance "Return to map" has been detected, the display control unit 13A displays the selection image that was previously displayed on the display unit 200 on the display unit 200 again. The system may also be configured to include the detection unit 14 of the first embodiment. In this case, similar to the first embodiment, even if there are multiple POI symbols 220 superimposed on the map displayed on the display unit 200, if there is only one POI symbol 220 in the selection area selected by the user via voice input, and the detection unit 14 does not detect any overlap between the dividing line separating the selection area and the other POI symbols 220 (for example, if the user selects "A3" in the selection image shown in Figure 5), the display control unit 13A may display the POI information shown in Figure 8 on the display unit 200 without enlarging the selection area. 【0057】<Processing Flow of Display Control Unit 13A> The processing flow of the display control unit 13A of the display control device 10A will be explained using Figures 14 and 15. This processing flow is started, for example, when the reception unit 11 receives an operation from the user to specify a POI to be targeted for detailed information display from the POI symbol on the map, and is repeatedly executed until a predetermined termination condition is met, such as when the detailed information of the designated POI is displayed or when the operation is canceled midway. 【0058】 As shown in Figure 14, the display control unit 13A causes the display unit 200 to display a selection image that includes a map, dividing lines, identification information, and POI symbols 220 (step S310). 【0059】 The display control unit 13A determines whether or not the reception unit 11 has received the input of identification information (step S320). If the display control unit 13A determines that the reception unit 11 has not received the input of identification information (NO in step S320), it returns to the standby state. If the display control unit 13A determines that the reception unit 11 has received the input of identification information (YES in step S320), it moves the process to step S330. 【0060】 The display control unit 13A sets the target area based on the identification information received by the reception unit 11 (step S330), and then proceeds to step S340. 【0061】 The display control unit 13A causes the extraction unit 15 to extract positional information of the POI symbols 220 that exist within the target area (step S340), and then proceeds to step S350. 【0062】 The display control unit 13A determines the enlarged display area based on the position information of the POI symbols present within the target area extracted by the extraction unit 15 (step S350), and proceeds to step S360 shown in Figure 15. 【0063】As shown in Figure 15, the display control unit 13A determines whether the number of POI symbols 220 present in the enlarged display area is less than or equal to a predetermined number (step S360). If the display control unit 13A determines that the number of POI symbols 220 present in the enlarged display area is not less than or equal to the predetermined number ("NO" in step S360), it displays a new selection image on the display unit 200 (step S370) and terminates the process. If the display control unit 13A determines that the number of POI symbols 220 present in the enlarged display area is less than or equal to the predetermined number ("YES" in step S360), it proceeds to step S380. 【0064】 The display control unit 13A determines whether there is one POI symbol 220 in the enlarged display area (step S380). If the display control unit 13A determines that there is more than one POI symbol 220 in the enlarged display area ("NO" in step S380), it displays an image containing the POI symbol 220 with an assigned identification number on the display unit 200 (step S390) and terminates the process. If the display control unit 13A determines that there is one POI symbol 220 in the enlarged display area ("YES" in step S380), it displays an image containing POI information on the display unit 200 (step S400) and terminates the process. 【0065】As described above, the display control device 10A according to this embodiment includes a reception unit 11 that receives input from the user, a display control unit 13A that displays a selection image on the display unit 200 that includes a map with POI symbols 220 and dividing lines superimposed on it, and identification information that identifies each of the map areas divided by the dividing lines, and an extraction unit 15 that, when the reception unit 11 receives input to select one piece of identification information, extracts POI symbols 220 within a target area composed of a selection area which is the map area corresponding to the one piece of identification information, and a predetermined range from among a plurality of map areas adjacent to the selection area. The display control unit 13A displays a new selection image on the display unit 200 that includes a map corresponding to an enlarged display area determined based on the position information of the POI symbols 220 extracted by the extraction unit 15. In other words, when the display control device 10A displays a new selection image on the display unit 200 that corresponds to the selection area selected by the user, it displays a map on the display unit 200 that includes all the POI symbols present in the target area determined based on the selection area selected by the user. As a result, the display control device 10A can easily display map information including the POI symbol 220 desired by the user, even if the POI symbol 220 is located across a dividing line. When a user wants to display a map that includes a POI symbol 220 located across a dividing line, they can specify any of the map areas that the POI symbol crosses, and the map information including the POI symbol 220 will be displayed. This allows the user to specify a selection area without hesitation. For example, without having to scrutinize the map image to determine which area of the divided map area the desired POI is located in, the user can specify any of the map areas that the POI symbol 220 of the desired POI crosses, and obtain a new selection image with an enlarged map area including the POI symbol 220. Furthermore, since the display control device 10A determines the enlarged display area based on the location information of the POI symbol 220 extracted by the extraction unit 15, the map including the POI symbol 220 located within the target area can be displayed on the display unit 200 at a greater enlargement. 【0066】 In this embodiment, the display control unit 13A of the display control device 10A determines the enlarged display area so that it includes all of the POI symbols 220 extracted by the extraction unit 15. As a result, the display control device 10A determines the enlarged display area based on the positional information of all the POI symbols 220 extracted by the extraction unit 15, and can display a more enlarged map containing all the POI symbols 220 present in the target area on the display unit 200. 【0067】 In this embodiment, the display control unit 13A of the display control device 10A displays a selection image on the display unit 200 that includes POI symbols 220 with identification numbers assigned to them, if the number of POI symbols 220 superimposed on the map displayed on the display unit 200 is less than or equal to a predetermined number. For example, if the number of POI symbols 220 present in the selection image to be displayed is five or less, the display control unit 13A displays POI symbols 220 with identification numbers such as serial numbers assigned to them. This allows the user to easily specify the POI symbols 220 for which they want to obtain POI information, even while driving, for example, by speaking an identification number. 【0068】 In this embodiment, the display control unit 13A of the display control device 10A displays a selection image containing POI information corresponding to the POI symbol 220 on the display unit 200 when there is only one POI symbol 220 superimposed on the map displayed on the display unit 200. This allows the user to obtain POI information without having to input an identification number. 【0069】The display unit 200 displayed by the display control device 10A in this embodiment is installed on a motorcycle. The reception unit 11 of the display control device 10A in this embodiment receives voice input from the user. Generally, when a user is driving a motorcycle, they cannot perform detailed operations such as selecting POI symbols 220 or selecting the map area to be displayed by touching the screen. Therefore, it is necessary for the user to perform operations such as selecting the display area or selecting POI symbols 220 by speaking. In other words, the user can specify the POI symbol from which they want to obtain POI information by speaking an identification number. As a result, the user can easily obtain information about the desired POI even while driving a motorcycle. 【0070】 <Modification 1> The program for the display control method of the display control devices 10 and 10A described above may be executed in the processor and memory of a navigation device installed in a vehicle to control the image to be displayed on the display unit of the navigation device. Alternatively, the program for the display control method of the display control devices 10 and 10A described above may be executed in a mobile terminal carried by the user (for example, a tablet or smartphone) to control the image to be displayed on the display unit of the mobile terminal. 【0071】 <Modification 2> The reception unit 11 of the display control devices 10 and 10A described above may, for example, detect operation information such as switches that can be operated while holding the handlebars, and accept input from the user. This allows the user to easily obtain desired POI information even while driving the motorcycle. 【0072】 <Modification 3> When the display control devices 10 and 10A described above display POI information corresponding to the POI symbol 220 desired by the user on the display unit 200, they may, for example, output voice information that reads out the POI information to a speaker attached to the user's helmet. This allows the user to easily grasp the desired POI information even while driving. 【0073】While embodiments of this invention have been described in detail above with reference to the drawings, all display control devices that a person skilled in the art can implement by appropriately modifying the design based on the above-described embodiments of the present invention also fall within the scope of the present invention, insofar as they encompass the gist of the present invention.
