That is, the display scale information generation unit 202g may perform comparison between the display range and the additional information area based on the distance, the coordinate amount, and the like. Further, the display scale information may be not only information indicating whether or not all guide routes and the like can be displayed at each scale, but also information indicating how much the guide routes and the like can be displayed (ratio and the like). For example, the display scale information generation unit 202g compares the route display range (additional information region) and the scale-specific display range, and if the entire route display range can be displayed on the screen (display unit 114), the entire route is displayed. Display scale information indicating that it is possible may be generated.

  Here, an example of the display scale information generation process in the present embodiment will be described with reference to FIGS. 6 and 7 are diagrams illustrating an example of display scale information generation processing in the present embodiment.

  As illustrated in FIG. 6, the display scale information generation unit 202g has each scale centered on the center position of the map based on the map information displayed on the display unit 114 of the terminal device 100 calculated by the display range calculation unit 202f. The display unit of the terminal device 100 performs comparison of the range of the additional information area based on the scale-specific display range of the display unit 114 of the map information of the map and the additional area information acquired by the area information acquisition unit 202d. In 114, display scale information relating to a scale at which additional information can be superimposed and displayed on the map information is generated. That is, the display scale information generation unit 202g compares the display area classified by scale with the additional information area using the center coordinates of the screen (display unit 114) as the center of the display area classified by scale, and adds them to the display area classified by scale. When the information area fits, display scale information indicating that the scale is such that all the guidance routes can be displayed is generated. That is, the display scale information generation unit 202g generates display scale information indicating that the scale is capable of displaying all of the additional information area when the scale is 1 / n3 or less.

  As shown in FIG. 7, the display scale information generation unit 202g adds the map size based on the scale-specific display range calculated by the display range calculation unit 202f and the addition area information acquired by the area information acquisition unit 202d. Based on the comparison with the size of the information area, display scale information relating to a scale at which the additional information can be superimposed and displayed on the map information on the display unit 114 of the terminal device 100 is generated.

  In addition, the map information display unit 102f is different in position information from the previous reception in the position acquisition unit 112 when the display range is set to change according to the change in the current position of the user of the terminal device 100. When a signal is received, a display range change instruction is acquired based on the position information signal, and the map information included in the output information stored in the output information file 106a in which the display range is changed based on the display range change instruction The additional information included in the output information stored in the output information file 106a, the current location information of the user of the terminal device 100 acquired by the current location information acquisition unit 102a, and the output stored in the output information file 106a Based on the display scale information included in the information, a scale change area that allows a map scale change via the input unit 118 is superimposed on the display unit 114. It may be shown. The map information display unit 102f superimposes the additional information included in the output information stored in the output information file 106a and the current location information of the user of the terminal device 100 acquired by the current location information acquisition unit 102a. The map scale can be changed via the input unit 118 based on the map information included in the output information stored in the output information file 106a and the display scale information included in the output information stored in the output information file 106a. The scale change areas to be displayed may be displayed side by side on the display unit 114.

  Further, the map information display unit 102f displays the output information file on the map information included in the output information stored in the output information file 106a, such as when a route guidance start request is input by the user via the input unit 118. The route information included in the additional information included in the output information stored in 106a, the current position information of the user of the terminal device 100 acquired by the current position information acquisition unit 102a, and / or the scale change area are superimposed. The route guidance may be executed by displaying on the display unit 114. Further, the map information display unit 102f may cause the display unit 114 to display display guide information such as TBT included in the guide information included in the output information. Further, the map information display unit 102f displays voice information corresponding to the display (voice guidance information associated with a traveling direction at a branch point or the like on the guidance route included in the output information) via the voice output unit 116. It may be output. Note that the route guidance (for example, display navigation and voice navigation) execution processing by the map information display unit 102f is performed when the processing from step SA-8 to step SA-16 is repeatedly performed after the start of route guidance (for example, (Until the terminal device 100 reaches the destination, waypoint, guidance point, etc.), it may be performed continuously (for example, display guidance on the guidance route is continuously given by the display unit 114, and the voice output unit 116 Voice guidance may be provided).

  In addition, when the display range of the map information is changed, the map information display unit 102f changes the display mode of the scale change area in conjunction with the change (for example, a change in form such as a scale scale that can display the entire guide route). Etc.). In addition, when the user is traveling on the guide route, the map information display unit 102f may change the display mode of the scale change area in conjunction with the remaining guide route. In addition, when the user reroutes, the map information display unit 102f may change the display mode of the scale change area in conjunction with the new guidance route. In addition, when there is a waypoint or a guide point in the guide route, the map information display unit 102f may change the form such as a scale that can display the entire guide route to the route point or the guide point. In this way, when there is a transit point or the like in the guide route, the user may select whether to reflect the guide route to the transit point or the like or the guide route to the destination in the display form of the scale change area. In addition, as a display form of the scale bar, a scale that can be displayed may be colored, or the scale bar may be displayed thickly. Further, the display form of the scale bar in the case of expressing the ratio may be that the color is shaded according to the ratio and / or the thickness is increased or decreased. For example, the map information display unit 102f may have a scale bar display form that allows the user to easily recognize the color and / or thickness of the scale that can display the entire guide route based on the display scale information.
