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 displays POI (Point of Interest) information (hereinafter also referred to as spot information), which is information about a specific location of interest to the user, on a display unit has become widespread. The display control device causes the display unit to display, for example, a map in which POI symbols (hereinafter also referred to as spot 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 spot symbols on a map, in order to reduce the number of spot symbols displayed within the screen, for example, the user designates the map area to be displayed and enlarges the display of the map. 【0003】 For example, as this type of technology, when displaying spot 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 the map area corresponding to the identification information input by voice from the user has been proposed (see, for example, Patent Document 1). 【0004】 Japanese Patent Application Laid-Open 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 a spot symbol existing at a position straddling the dividing line, the user may be confused about which map area to specify, which is an example of a problem. 【0006】 The present invention has been made in view of the problems exemplified 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 spot 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 that receives input from a user; a display unit that displays a selection image for selecting a spot symbol on a map, which includes a map with dividing lines superimposed on it; and a display control unit that updates the selection image when the reception unit receives input for selecting a selection area, which is one of a plurality of map areas divided by the dividing lines, wherein the display control unit updates the selection image by displaying a new selection image determined based on whether or not the spot symbol is displayed partially or entirely within an annular area of ​​a predetermined width adjacent to the outside of the dividing lines that divide the selection area, or a new selection image determined based on the spot symbol displayed partially or entirely within the selection area. 【0008】 To solve the above problems, the invention described in claim 8 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 receives input from a user; the display control unit displays a selection image on a display unit, which is an image for selecting a spot symbol on a map and includes a map with superimposed dividing lines, and updates the selection image when the reception unit receives input for selecting a selection area, which is one of a plurality of map areas divided by the dividing lines; and the display control unit, when updating the selection image, displays a new selection image determined based on whether or not the spot symbol is displayed partially or entirely within an annular area of ​​a predetermined width adjacent to the outside of the dividing lines that divide the selection area, or a new selection image determined based on the spot symbol displayed partially or entirely within the selection area. 【0009】To solve the above problems, the invention described in claim 9 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 perform the following steps: a first step of receiving input from a user; a second step of causing a selection image, which is an image for selecting a spot symbol on a map and includes a map with dividing lines superimposed on it, to be displayed on a display unit, and when the reception unit receives input for selecting a selection area, which is one of a plurality of map areas divided by the dividing lines, the selection image is updated; and a third step of causing the computer to perform the following steps when updating the selection image: a new selection image determined based on whether or not the spot symbol is displayed with part or whole included in an annular area of ​​a predetermined width adjacent to the outside of the dividing lines that divide the selection area, or a new selection image determined based on the spot symbol displayed with part or whole included in the selection area. 【0010】This figure shows the configuration of a display control device according to the first embodiment of the present invention.

This figure shows the processing flow of a display control device according to the second embodiment of the present invention. This figure shows an annular area and an expanded determination area set by a display control device according to an application example 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 with spot symbols 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 receives input to select one piece of identification information, the display control unit displays a new selection image on the display unit that includes a map corresponding to a target area, which is a selection area that corresponds 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 areas adjacent to the selected area. As a result, the display control device can easily display map information that includes a spot symbol desired by the user, even if the spot symbol desired by the user is located across a dividing line. When a user wants to display a map that includes a spot symbol located across a dividing line, they can specify one of the map areas that the spot symbol crosses to display the map information that includes the spot symbol. This allows users to specify the selection area without hesitation. 【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 spot symbol. When the display control unit detects an overlap between the dividing line that separates a selected area and a spot 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 spot 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 spot 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 spot symbol, it does not need to display the 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 spot 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 causes the display unit to display a selection image containing spot symbols with identification numbers (hereinafter referred to as identification codes) if the number of spot 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 spot symbols in the selection image to be displayed is five or less, the display control unit displays spot symbols with identification codes such as serial numbers. This allows the user to easily specify the spot symbols for which they want to obtain spot information, even while driving, for example, by speaking the identification code. 【0014】 In this embodiment, the display control unit of the display control device displays a selection image containing spot information corresponding to a spot symbol on the display unit when there is only one spot symbol superimposed on the map displayed on the display unit. This allows the user to obtain spot information without having to perform operations such as inputting an identification code. 【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 spot symbols or map areas to display by touching the screen. Therefore, it is necessary to perform operations such as selecting display areas or spot symbols using the user's voice. In other words, the user can specify the spot symbol from which they want to obtain spot information by speaking an identification code. As a result, the user can easily obtain information about the desired POI even while riding a motorcycle. 【0016】 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 a display unit, which is an image for selecting a spot symbol on a map and includes a map with dividing lines superimposed on it, and updates the selection image when the reception unit receives input for selecting a selection area, which is one of a plurality of map areas divided by dividing lines. When updating the selection image, the display control unit displays a new selection image determined based on whether or not a spot symbol is displayed with part or all of it included within a predetermined width ring area adjacent to the outside of the dividing lines that divide the selection area. In other words, the display control unit switches the selection image displayed on the display unit depending on whether or not a spot symbol is displayed with part or all of it included within a ring area. As a result, the display control unit can display a new selection image that includes the spot symbol desired by the user. 【0017】The display control unit of the display control device according to this embodiment displays a new selection image that includes a map corresponding to a target area consisting of the selected area and a predetermined range from a plurality of map areas adjacent to the selected area, if there is a spot symbol displayed that is partially or entirely contained within the ring area when updating the selection image. If there is no spot symbol displayed that is partially or entirely contained within the ring area, the display control unit displays a new selection image that includes a map corresponding to the selected area. For example, when updating the selection image, if there is a spot symbol displayed that is partially or entirely contained within the ring area, the display control unit displays a new selection image that includes a map corresponding to a target area consisting of the selected area and a predetermined range from a plurality of map areas adjacent to the selected area. In other words, the display control unit displays a new selection image on the display unit that includes the spot symbol displayed within the selected area and the spot symbol displayed that is partially or entirely contained within the ring area. As a result, the display control unit can, for example, display a new selection image that includes the spot symbol desired by the user, even if, at the moment a user in a moving vehicle attempts to specify a selection area using voice input or touch panel input, a spot symbol that was overlapping with a lane line moves outside the lane line. 【0018】 In this embodiment, the display control unit of the display control device updates the selection image and, if the number of spot symbols displayed that are partially or entirely contained within the extended determination area consisting of the selection area and the annular area is less than or equal to a predetermined number, displays a new selection image to which an identification code has been assigned to the spot symbols. In other words, the display control unit displays a new selection image to which an identification code has been assigned to the spot symbols if the number of spot symbols displayed that are partially or entirely contained within the extended determination area, which is a combination of the selection area specified by the user and an annular area of ​​a predetermined width adjacent to the outside of the dividing line separating the selection area, is less than or equal to a predetermined number. As a result, even while driving, the user can easily specify the spot symbols for which they want to obtain spot information by, for example, uttering an identification code. 【0019】 In this embodiment, the display control unit of the display control device updates the selection image. If there is only one spot symbol displayed that is partially or entirely contained within the extended determination area, which consists of a selection area and a ring area, the display control unit displays a new selection image containing spot information corresponding to that spot symbol. This allows the user to obtain spot information without having to perform operations such as inputting an identification code. 【0020】 The display control device according to this embodiment includes a reception unit that receives input from the user, and a display control unit that displays a selection image on a display unit, which is an image for selecting a spot symbol on a map and includes a map with dividing lines superimposed on it, and updates the selection image when the reception unit receives input for selecting a selection area, which is one of a plurality of map areas divided by dividing lines. When updating the selection image, the display control unit displays a new selection image determined based on the spot symbol displayed, which is partly or entirely included within the selection area. As a result, the display control device can easily display map information including the spot symbol desired by the user, even if the spot symbol desired by the user is located across a dividing line. When a user wants to display a map that includes a spot symbol located across a dividing line, they can display the map information including the spot symbol by specifying one of the map areas that the spot symbol crosses. As a result, the user can specify a selection area without hesitation. 【0021】In this embodiment, the display control unit of the display control device updates the selection image. If there are spot symbols overlapping with the dividing lines that separate the selection area, it displays a new selection image that includes a map corresponding to the target area, which consists of the selected area and a predetermined range from among a plurality of map areas adjacent to the selected area. If there are no spot symbols overlapping with the dividing lines that separate the selection area, the display control unit displays a new selection image that includes a map corresponding to the selected area. When the display control device displays a map corresponding to a selection area selected by the user, it determines whether or not there is an overlap between the dividing lines that separate the selection area and the spot symbols. In other words, if the display control device determines that there is no overlap between the dividing lines that separate the selection area selected by the user and the spot symbols, it does not need to display the map areas adjacent to the selected area, and therefore displays a new selection image that includes a map corresponding to the selected area on the display unit. This allows the display control device to display map information including the spot symbols desired by the user in a larger size on the display unit. 【0022】 In this embodiment, the display control unit of the display control device updates the selection image and, if the number of spot symbols displayed that are partially or entirely included within the selection area is less than or equal to a predetermined number, displays a new selection image with identification codes assigned to the spot symbols. For example, if the number of spot symbols present in the selection image to be displayed is five or less, the display control unit displays spot symbols to which identification codes such as serial numbers have been assigned. This allows the user to easily specify the spot symbols for which they want to obtain spot information, even while driving, for example, by speaking an identification code. 【0023】 In this embodiment, the display control unit of the display control device updates the selection image. If there is only one spot symbol displayed within the selection area, either partially or entirely, it displays a new selection image containing the spot information corresponding to that spot symbol. This allows the user to acquire spot information without having to perform operations such as inputting an identification code. 【0024】 <Examples> Hereinafter, examples of the present invention will be described with reference to Figures 1 to 15. 【0025】 <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. 【0026】 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. 【0027】 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. 【0028】 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 spot symbols indicating the locations of POIs are superimposed. Details of the image that the display control device 10 displays on the display unit 200 will be described later. 【0029】 <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. 【0030】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 code from the user's speech content, for example, it outputs the detected identification code to the display control unit 13, which will be described later. The above-mentioned identification information and identification code will be described later. 【0031】 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, spot information (POI information). Examples of the spot information mentioned above include 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 restaurants, department stores, ATMs, convenience stores, gas stations, tourist spots, theme parks, etc. The map information and spot information stored in the storage unit 12 are updated as needed. 【0032】In this embodiment, the display control unit 13 controls the processing of the entire 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 locations 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 spot information (for example, ATMs) and map information related to POIs (for example, ATMs) within 5 km of the user's current location from the storage unit 12. 【0033】 The display control unit 13 displays a selection image on the display unit 200 that includes a map with spot 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 spot symbols 220 indicating the location of the ATM and dividing lines superimposed on it, based on spot 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 displays the user's current location mark 230 superimposed on the map on the display unit 200, 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 displays identification information that identifies each of the map areas divided by the dividing lines on the display unit 200 so as not to overlap with the map display described above. 【0034】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". 【0035】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". 【0036】 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). 【0037】In this embodiment, the display control unit 13, for example, displays a new selection image on the display unit 200, including a map corresponding to the target area, if it detects an overlap between a dividing line separating the selected area and a spot symbol 220, and displays a new selection image on the display unit 200, including a map corresponding to the selected area, if it does not detect an overlap between a dividing line separating the selected area and a spot symbol 220. In this embodiment, for example, when the reception unit 11 receives input to select one piece of identification information and the selected area is determined, the display control unit 13 obtains a detection result from the detection unit 14 (described later) indicating that there is an overlap between a dividing line separating the user-selected selected area (for example, "B-2" in Figure 5) and a spot symbol 220, and then 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 spot 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 spot 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 spot symbol 220, the dividing line, and the identification information. In this way, if the number of spot symbols 220 present on the map shown in the selection image is large and it is difficult for the user to select the desired spot symbol 220, the user can repeatedly input voice information for the identification information of the map area where the desired spot symbol 220 exists in the selection image, thereby enlarging the map and reducing the number of spot symbols 220 present on the map. 【0038】If the number of spot 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 spot symbols 220 to which an identification code has been assigned. In this embodiment, for example, if the number of spot 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 on which spot symbols 220 to which an identification code has been assigned, as shown in Figure 7, have been superimposed. 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 spot information corresponding to the spot symbol 220 to which the identification code "number 2" has been assigned from the storage unit 12 and displays it on the display unit 200. 【0039】If there is only one spot symbol 220 superimposed on the map displayed on the display unit 200, the display control unit 13 displays a selection image containing spot information corresponding to that spot symbol 220 on the display unit 200. In this embodiment, for example, if there is only one spot symbol 220 in the selection image to be displayed on the display unit 200, the display control unit 13 displays spot 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 "Go here" has been detected, the display control unit 13 calculates the route from the user's current location to the location of the spot symbol 220 displaying the spot 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 displays the selection image that was previously displayed on the display unit 200 again on the display unit 200. Furthermore, even if there are multiple spot symbols 220 superimposed on the map displayed on the display unit 200, if there is only one spot 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 spot 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 spot information as shown in Figure 8 on the display unit 200 without enlarging the selection area. 【0040】When the reception unit 11 receives input indicating that it has selected a single piece of identification information, the detection unit 14 detects the overlap between the dividing line that separates the selected area and the spot symbol 220. In this embodiment, for example, the detection unit 14 can determine whether there are any spot symbols 220 that overlap with the dividing line that separates the selected area selected by the user in the selection image, based on the map location information of the dividing line that separates the selected area, the location information of POIs (Points of Interest) located 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 about the selected area from the display control unit 13, and perform a geometric analysis on the dividing line that separates the selected area to determine whether there are any spot symbols 220 that overlap with the dividing line that separates the selected area selected by the user. In this embodiment, for example, the detection unit 14 outputs the detection result to the display control unit 13. 【0041】 <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 targeted for detailed information display from a spot symbol on the map, and is repeatedly executed until a predetermined termination condition is met, such as when the detailed information of the POI specified as the target is displayed or when the operation is canceled midway. 【0042】 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 spot symbols 220 (step S110). 【0043】The display control unit 13 determines whether the reception unit 11 has received an input of identification information (step S120). When the display control unit 13 determines that the reception unit 11 has not received an input of identification information ( "NO" in step S120), it returns the process and shifts to the standby state. When the display control unit 13 determines that the reception unit 11 has received an input of identification information ( "YES" in step S120), it shifts the process to step S130. 【0044】 When the display control unit 13 determines that the reception unit 11 has received an input of identification information ( "YES" in step S120), it acquires a detection result regarding the presence or absence of an overlap between a dividing line that divides the selection area selected by the user from the detection unit 14 and the spot symbol 220 (step S130), and shifts the process to step S140. 【0045】 The display control unit 13 determines whether it has acquired a detection result indicating that there is an overlap between a dividing line that divides the selection area selected by the user and the spot symbol 220 from the detection unit 14 (step S140). When the display control unit 13 determines that it has acquired a detection result indicating that there is an overlap between a dividing line that divides the selection area selected by the user and the spot symbol 220 from the detection unit 14 ( "YES" in step S140), it shifts the process to step S150. When the display control unit 13 determines that it has acquired a detection result indicating that there is no overlap between a dividing line that divides the selection area selected by the user and the spot symbol 220 from the detection unit 14 ( "NO" in step S140), it shifts the process to step S160. 【0046】 When the display control unit 13 determines that it has acquired a detection result indicating that there is an overlap between a dividing line that divides the selection area selected by the user and the spot symbol 220 from the detection unit 14 ( "YES" in step S140), it acquires map information corresponding to a target area including 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 shifts the process to step S170 in FIG. 10. 【0047】When the display control unit 13 determines that it has acquired a detection result from the detection unit 14 indicating that there is no overlap between the dividing line that divides the selected area selected by the user and the spot symbol 220 ( "NO" in step S140), it acquires map information corresponding to the selected area from the storage unit 12 (step S160) and shifts the process to step S170 in FIG. 10. 【0048】 As shown in FIG. 10, the display control unit 13 determines whether the number of spot symbols 220 superimposed on the map to be displayed is less than or equal to a predetermined number (step S170). When the display control unit 13 determines that the number of spot symbols 220 superimposed on the map to be displayed is not less than or equal to the predetermined number ( "NO" in step S170), it causes the display unit 200 to display a new selection image (step S180) and ends the process. When the display control unit 13 determines that the number of spot symbols 220 superimposed on the map to be displayed is less than or equal to the predetermined number ( "YES" in step S170), it shifts the process to step S190. 【0049】 The display control unit 13 determines whether the number of spot symbols 220 superimposed on the map to be displayed is one (step S190). When the display control unit 13 determines that the number of spot symbols 220 superimposed on the map to be displayed is not one ( "NO" in step S190), it causes the display unit 200 to display an image including the spot symbol 220 to which an identification code is assigned (step S200) and ends the process. When the display control unit 13 determines that the number of spot symbols 220 superimposed on the map to be displayed is one ( "YES" in step S190), it causes the display unit 200 to display an image including spot information (step S210) and ends the process. 【0050】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 spot 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 ​​the 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 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 area adjacent to the selected area. As a result, the display control device 10 can easily display map information including the spot symbol 220 desired by the user, even if the spot symbol 220 desired by the user is located across a dividing line. When a user wants to display a map that includes a spot symbol 220 located across a dividing line, they can specify one of the map areas that the spot symbol 220 crosses to display the map information including the spot symbol 220. 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 spot symbol 220 of the desired POI crosses to obtain a new selection image with an enlarged map area including the spot symbol 220. 【0051】The display control device 10 according to this embodiment includes a detection unit 14 that detects the overlap between a dividing line that separates a selected area and a spot symbol 220. When the display control unit 13 detects an overlap between the dividing line that separates a selected area and a spot symbol 220, it displays a new selection image on the display unit 200 that includes a map corresponding to the target area. When the display control device 10 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 spot symbol 220. In other words, when the display control device 10 determines that there is no overlap between the dividing line that separates the selected area selected by the user and the spot symbol 220, 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 200 that includes a map corresponding to the selected area. This allows the display control device 10 to enlarge the map information, including the spot symbols 220 desired by the user, and display it on the display unit 200. 【0052】 In this embodiment, the display control unit 13 of the display control device 10 displays a selection image on the display unit 200 that includes spot symbols 220 with identification codes assigned to them, if the number of spot 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 spot symbols 220 present in the selection image to be displayed is five or less, the display control unit 13 displays spot symbols 220 with identification codes such as serial numbers assigned to them. This allows the user to easily specify the spot symbols 220 for which they want to obtain spot information, even while driving, for example, by speaking an identification code. 【0053】In this embodiment, the display control unit 13 of the display control device 10 displays a selection image containing spot information corresponding to a spot symbol 220 on the display unit 200 when there is only one spot symbol 220 superimposed on the map displayed on the display unit 200. This allows the user to acquire spot information without having to perform operations such as inputting an identification code. 【0054】 The display unit 200 displayed by the display control device 10 according to this embodiment is installed on a motorcycle. The reception unit 11 of the display control device 10 according to this embodiment receives voice input from the user. Generally, when a user is driving a motorcycle, they cannot perform detailed operations such as selecting a spot symbol 220 or selecting a map area to display by touching the screen. Therefore, for example, the user needs to select a spot symbol 220 by speaking. In other words, the user can specify the spot symbol 220 from which they want to obtain spot information by speaking an identification code. As a result, the user can easily obtain information about the desired POI even while driving a motorcycle. 【0055】 <Second Embodiment> The display control device 10A according to this embodiment will be described with reference to Figures 11 to 15. Components that are denoted by the same reference numerals as in the first embodiment have the same function, so their detailed explanation will be omitted. In this embodiment, the display control device 10A controls the image to be displayed on a display unit 200 installed in a vehicle such as a bicycle, motorcycle, or four-wheeled vehicle. The following will explain the case in which the display control device 10A controls the image to be displayed on a display unit 200 installed in a motorcycle. 【0056】 <Configuration of the display control device 10A> As shown in Figure 11, the display control device 10A is configured to include a reception unit 11, a storage unit 12, a display control unit 13A, and an extraction unit 15. 【0057】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 locations 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 spot information (for example, ATMs) and map information related to POIs (for example, ATMs) within 5 km of the user's current location from the storage unit 12. 【0058】 The display control unit 13A causes the display unit 200 to display a selection image that includes a map with spot 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. 【0059】In this embodiment, the display control unit 13A determines a target area consisting of a selection area, which is a map area corresponding to the selection information, and a predetermined range from among a plurality of map areas adjacent to the selection area, when the reception unit 11 receives an input to select a single piece of identification information. In this embodiment, the display control unit 13A determines the map area indicated by "B no 2" as the selection area when the reception unit 11 receives a detection result indicating that, for example, "B no 2" has been detected from the user's utterance. In this embodiment, the display control unit 13A determines a target area consisting of the selection area "B no 2" and a predetermined range from among the map areas adjacent to the selection area "B no 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 the explanation is omitted. In this embodiment, the display control unit 13A outputs information regarding the determined target area and spot information desired by the user (for example, information regarding ATMs, etc.) to the extraction unit 15. 【0060】The extraction unit 15 will now be described. When the reception unit 11 receives input to select a single piece of identification information, the extraction unit 15 extracts spot symbols 220 within a target area, which consists of a selection area that corresponds 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 spot information desired by the user (for example, information about an ATM), the extraction unit 15 refers to the map information and spot 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. 【0061】 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 location information of the spot 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 spot 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 location 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. 【0062】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 spot 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 with 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. 【0063】 If the number of spot 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 spot symbols 220 to which an identification code has been assigned. In this embodiment, for example, if the number of spot 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 symbols 220 to which an identification code has been assigned to display on the display unit 200. 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 spot information corresponding to the spot symbol 220 to which the identification code "number 2" has been assigned from the storage unit 12 and displays it on the display unit 200. 【0064】If there is one spot 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 spot information corresponding to the spot symbol 220. In this embodiment, for example, if there is one spot 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 spot information (for example, name, location information, business hours, etc.) as shown in Figure 8. In this embodiment, for example, if the display control unit 13A receives a detection result from the reception unit 11 indicating that the utterance "I want to go here" has been detected, it calculates the route from the user's current location to the location of the spot symbol 220 displaying the spot information, and displays the guidance route, etc., on the display unit 200. In this embodiment, for example, if the reception unit 11 has detected the utterance "return to map", the display control unit 13A will display 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 spot symbols 220 superimposed on the map displayed on the display unit 200, if there is only one spot 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 spot symbols 220 (for example, if the user selects "A3" in the selection image shown in Figure 5), the display control unit 13A may display spot information as shown in Figure 8 on the display unit 200 without enlarging the selection area. 【0065】<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 a spot symbol on the map, and is repeatedly executed until a predetermined termination condition is met, such as when the detailed information of the POI specified as the target is displayed or when the operation is canceled midway. 【0066】 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 spot symbols 220 (step S310). 【0067】 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. 【0068】 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. 【0069】 The display control unit 13A causes the extraction unit 15 to extract positional information of the spot symbols 220 present within the target area (step S340), and then proceeds to step S350. 【0070】 The display control unit 13A determines the enlarged display area based on the position information of the spot symbols 220 that exist within the target area extracted by the extraction unit 15 (step S350), and proceeds to step S360 shown in Figure 15. 【0071】As shown in Figure 15, the display control unit 13A determines whether the number of spot 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 spot 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 spot 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. 【0072】 The display control unit 13A determines whether or not there is one spot symbol 220 in the enlarged display area (step S380). If the display control unit 13A determines that there is more than one spot symbol 220 in the enlarged display area ("NO" in step S380), it displays an image including the spot symbol 220 to which the identification code has been assigned on the display unit 200 (step S390) and terminates the process. If the display control unit 13A determines that there is one spot symbol 220 in the enlarged display area ("YES" in step S380), it displays an image including spot information on the display unit 200 (step S400) and terminates the process. 【0073】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 spot 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 spot symbols 220 within a target area consisting 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 spot 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 spot symbols 220 that exist within 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 spot symbol 220 desired by the user, even if the spot symbol 220 desired by the user is located across a dividing line. When a user wants to display a map that includes a spot symbol 220 located across a dividing line, they can specify any of the map areas that the spot symbol 220 crosses, and the map information including the spot 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 spot symbol 220 of the desired POI crosses, and obtain a new selection image with an enlarged map area including the spot symbol 220.Furthermore, since the display control device 10A determines the enlarged display area based on the positional information of the spot symbols 220 extracted by the extraction unit 15, it can display a more enlarged map containing the spot symbols 220 that are within the target area on the display unit 200. 【0074】 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 spot 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 spot symbols 220 extracted by the extraction unit 15, so that the map including all the spot symbols 220 present in the target area can be displayed on the display unit 200 at a greater magnification. 【0075】 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 spot symbols 220 with identification codes assigned to them, if the number of spot 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 spot symbols 220 present in the selection image to be displayed is five or less, the display control unit 13A displays spot symbols 220 with identification codes such as serial numbers assigned to them. This allows the user to easily specify the spot symbols 220 for which they want to obtain spot information, even while driving, for example, by speaking an identification code. 【0076】 In this embodiment, the display control unit 13A of the display control device 10A displays a selection image containing spot information corresponding to the spot symbol 220 on the display unit 200 when there is only one spot symbol 220 superimposed on the map displayed on the display unit 200. This allows the user to obtain spot information without having to input an identification code. 【0077】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 a spot symbol 220 or selecting a map area to display by touching the screen. Therefore, it is necessary for the user to perform operations such as selecting the display area or selecting a spot symbol 220 by speaking. In other words, the user can specify the spot symbol from which they want to obtain spot information by speaking an identification code. As a result, the user can easily obtain information about the desired POI even while driving a motorcycle. 【0078】 <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. 【0079】 <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. 【0080】 <Modification 3> When the display control devices 10 and 10A described above display spot information corresponding to a spot symbol 220 desired by the user on the display unit 200, they may, for example, output audio information such as reading out the spot information to a speaker attached to the user's helmet. This allows the user to easily grasp the desired spot information even while driving. 【0081】<Modification 4> The reception unit 11 described above may, instead of voice input, accept user input based on sensor output from a touch panel installed on the display unit 200. In this case, the user can directly specify the desired area on the touch panel from among the map areas divided by dividing lines, so it is not necessary to display identification information. Alternatively, the reception unit 11 may accept the selection of an area by the user's speech and touch operation. 【0082】 <Modification 5> The display control units 13 and 13A described above, for example, when updating the selection image, enlarge the map of the selection area specified by the user and display it on the display unit 200. However, if the number of spot symbols 220 in the selection area is less than or equal to a predetermined number, the display control units 13 and 13A may not enlarge the map of the selection area. If the number of spot symbols 220 in the selection area is less than or equal to a predetermined number, the display control units 13 and 13A do not update the displayed map, but instead assign identification codes to the spot symbols 220 in the selection area and display them. This allows the user to easily specify the spot symbol 220 for which they want to obtain spot information by, for example, uttering an identification code. Furthermore, if there is only one spot symbol 220 in the selection area, the display control units 13 and 13A may display the spot information corresponding to that spot symbol 220 on the display unit 200 without updating the displayed map. This allows the user to obtain spot information without having to input an identification code. 【0083】<Modification 6> The display control devices 10 and 10A described above determined the display mode of the selection image based on whether or not there was an overlap between the dividing line that separates the selection area and the spot symbol 220. However, for example, the display mode of the selection image may be determined based on whether or not there is a spot symbol 220 displayed in an annular area of ​​a predetermined width adjacent to the outside of the dividing line that separates the selection area. In other words, when updating the selection image, the display control units 13 and 13A display a new selection image determined based on whether or not there is a spot symbol displayed that is partially or entirely included in an annular area of ​​a predetermined width adjacent to the outside of the dividing line that separates the selection area. Here, the annular area will be explained using Figure 16 as an example, when the user selects "B-2" as the selection area. 【0084】 As shown in Figure 16, the ring area is an area of ​​a predetermined width (hatched with diagonal lines) adjacent to the outside of the dividing line that separates the selected area "B-2". The predetermined width is set to, for example, 100m so that spot symbols outside the selected area selected by the user and in the vicinity of that selected area can be detected. Note that the predetermined width may be varied according to the scale of the map displayed on the display unit 200. When updating the selection image, for example, if there are no spot symbols 220 displayed that are partially or entirely included within the ring area, the display control units 13 and 13A will display a new selection image that includes the map corresponding to the selected area. In other words, the display control units 13 and 13A will display a new selection image on the display unit 200 that includes a spot symbol 220 that is displayed entirely within the selected area. This allows the display control units 13 and 13A to display a new selection image that includes the spot symbol desired by the user. 【0085】The display control units 13 and 13A, for example, when updating the selection image, if there is a spot symbol 220 displayed that is partially or entirely included within the annular area, will display a new selection image on the display unit 200 that includes both the spot symbol 220 displayed within the selection area and the spot symbol 220 that is partially or entirely included within the annular area. Here, the spot symbol 220 that is partially included within the annular area includes the spot symbol 220 that was overlapping the lane line. As the vehicle (user) moves, the positional relationship between the position of the spot symbol and the lane line changes, so the display control units 13 and 13A control the display mode of the selection image to be displayed depending on whether or not there is a spot symbol 220 that is partially or entirely included within the annular area. As a result, the display control units 13 and 13A can display a new selection image that includes the spot symbol desired by the user, even if, for example, at the moment a user moving in a vehicle attempts to specify a selection area using a touch operation, a spot symbol that was overlapping the lane line has moved to a position outside the lane line where it no longer overlaps the lane line. 【0086】 In other words, in the display control device according to this embodiment, the display control units 13 and 13A may, for example, display a selection image determined based on the presence or absence of a spot symbol 220 that is partially or entirely included in the selection area, according to instruction information regarding the display mode obtained from the user via the reception unit 11, or they may display a selection image determined based on the presence or absence of a spot symbol 220 that is partially or entirely included in the annular area. 【0087】When updating the selection image, the display control units 13 and 13A display a new selection image with an identification code assigned to the spot symbol if the number of spot symbols displayed that are partially or entirely included within the extended determination area, which consists of the selection area and the annular area, is less than or equal to a predetermined number. In other words, as shown in Figure 16, the display control units 13 and 13A display a new selection image with an identification code assigned to the spot symbol if the number of spot symbols 220 displayed that are partially or entirely included within the extended determination area, which is a combination of the selection area specified by the user (for example, "B-2") and an annular area of ​​a predetermined width adjacent to the outside of the dividing line separating the selection area (the area hatched with diagonal lines), is less than or equal to a predetermined number. This allows the user to easily specify the spot symbol for which they want to obtain spot information, for example, by speaking an identification code, even while driving. 【0088】 When updating the selection image, the display control units 13 and 13A display a new selection image containing spot information corresponding to a spot symbol if there is only one spot symbol 220 displayed that is partially or entirely included within the extended determination area consisting of a selection area and an annular area. This allows the user to obtain spot information without having to perform operations such as inputting an identification code. 【0089】 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.
