As a result, it is possible to simultaneously see and grasp the detailed information around the current position and the surrounding wide area information.
JP-A-7-332991 JP 2002-5672 A

  However, in a conventional navigation device or an application that runs on a personal computer, it is possible to see only one detailed view near an arbitrary point at a time. In particular, in Patent Document 1, a wide-area map is displayed on one display screen. If there are multiple points that you want to enlarge when you are doing, you will have to press and release your finger many times to display the frame of the detailed map to find the desired point, which makes the operation complicated There was a problem. In particular, in Patent Document 2, the area to be enlarged and displayed is specialized only around the current location.

  Further, when maps of different scales are simultaneously displayed on one display screen, map display according to the scale of a detailed map different from the scale of the main map in a wide area cannot be performed by a simple operation. That is, when the enlarged map for displaying the detailed map is freely moved up, down, left and right on one display screen on which the wide area map is displayed, the enlarged map is moved in accordance with the scale of the wide area map. Since the detailed map moves greatly, there is a problem that it is difficult to move the detailed map in a minute region.

  The present invention has been made against this background. That is, according to the present invention, an information display device excellent in operability that can be enlarged and displayed by a simple operation even when there are a plurality of arbitrary points to be enlarged, and can move a detailed map in a minute region. The purpose is to provide.

  In order to achieve the above object, an information display device according to the present invention includes information storage means for storing information to be provided to a user, display means such as a liquid crystal display or an organic EL display, and physical contact such as a touch panel. Input means for inputting an instruction, an enlarged view display means for determining a predetermined area from the inputted arbitrary point, and displaying an enlarged view superimposed on the main view displayed on the display means, and for the inputted arbitrary point An enlarged view moving means for moving the display position of the enlarged view on the main view according to the movement and displaying the enlarged view at the position according to the movement of the arbitrary point is provided. The shape of the enlarged view may be any shape such as a circle, a quadrangle, or a polygon, and the operability and visibility may be improved, for example, the display center may be above the input arbitrary point. You may make it provide the setting means which sets these conditions.

  In addition, when the main map is configured to have a wide control area that performs control in consideration of the scale of a wide area and a detailed control area that performs control in consideration of the scale of detail, and instructing to move the enlarged map in the wide control area When the enlarged view is moved and displayed at the scale of the main view and an instruction to move the enlarged view is given in the detailed control area, the enlarged view is moved and displayed at the scale of the detailed view. For example, the outer frame of the enlarged view may be a wide area control area, and the inside of the enlarged view may be a detailed control area. When an arbitrary point is input in the enlarged view or in the detailed control area, the display position of the enlarged view on the main view is moved to an arbitrary point, and an enlarged view with the arbitrary point as the display center is displayed. Good.

  In addition, the display center of the enlarged view coincides with the coordinate value for displaying the enlarged view of the main view simultaneously with the movement of the enlarged view or after the movement is completed.

  Also, when pressed for a long time in the enlarged view or in the detailed control area, the scale of the main view is changed to the same scale as the enlarged view and displayed, or the scale of the enlarged view is changed. The scale is changed to a more detailed scale than the scale.

  As is apparent from the means for solving the above-described problems, the information display device of the present invention performs a plurality of points by performing a simple operation in response to a contact point movement instruction even if there are a plurality of arbitrary points to be enlarged. Can be continuously displayed, and the user can display an enlarged view of a desired size and scale. In particular, when an input instruction is made by physical contact with a display means such as a touch panel, the movement of the enlarged view on the display screen and the input operation move in conjunction with each other, and the operability can be improved. It becomes possible.

  In addition, since the information display device of the present invention is provided with the wide area control area and the detailed control area, it is possible to move the enlarged view corresponding to each scale with a simple operation, and to reduce and enlarge the main view. Even when the scales of the figures are greatly different, it is possible to provide a map display device excellent in operability capable of displaying an enlarged map corresponding to each scale.

  Hereinafter, the information display device according to the first and second embodiments of the present invention will be specifically described with reference to the drawings. As an example of the information display device of the present embodiment, a case where the present invention is applied to a navigation device installed in a moving body such as an automobile is taken as an example.

(Embodiment 1)
FIG. 1 is a configuration diagram showing the overall configuration of the navigation device of the present embodiment. The navigation device 1 includes a control unit 10, a map information storage unit 11, a positioning unit 12, an input unit 13, and a display unit 14. In each drawing, components not related to the present invention are omitted.

  In FIG. 1, a control unit 10 (10A will be described in detail in Embodiment 1 and 10B will be described in detail in Embodiment 2) is a CPU or MPU that controls the operation of the entire navigation device 1. The map information storage unit 11 is, for example, an HDD or a DVD in which map information such as road and intersection data is stored. However, the present invention is not limited to this, and a configuration in which information stored in the map information storage unit 11 is downloaded from the center facility each time by a communication unit (not shown) (for example, a mobile phone) is also possible. The map information storage unit 11 stores different scale maps. The positioning unit 12 is a means for positioning the current position, speed, and direction of the vehicle, such as a GNSS (Global Navigation Satellite System) receiver, a vehicle speed sensor, a gyro sensor, and the like. The GNSS receiver is, for example, a GPS receiver, which receives a radio wave from a satellite and demodulates it to calculate the position of the receiver. The input unit 13 is a means for a user to input an instruction to the navigation device 1 and is a touch panel, a remote controller, a voice input device, or the like. In the following, the input unit 13 is a touch panel that detects finger contact and slide, and is disposed on the display unit 14. Processing associated with the map enlargement operation by the input unit 13 will be described in detail later. The display unit 14 is a liquid crystal display, an organic EL display, or the like for displaying map information or the like stored in the map information storage unit 11.

  In the navigation apparatus 1 configured as described above, the control unit 10A can control basic functions as a navigation apparatus described below. A route search can be performed based on the current position acquired by the positioning unit 12 and the destination input from the input unit 13, and the result can be displayed on the display unit 14. In addition, the vehicle position mark can be superimposed and displayed on the map by a map matching process or the like based on data on the current position, speed, and direction of the vehicle obtained by the positioning unit 12. Further, when the vehicle position reaches a guidance guide point on the route, an enlarged view of the intersection can be displayed on the display unit 14, or a guide voice can be output from a voice output unit such as a speaker (not shown).

  Further, in the navigation device according to the first embodiment, the user can make various settings through the screen displayed on the display unit 14. FIG. 2 shows an example of a “touch panel setting” screen, in which a user can freely select and set a mode set by short-pressing the touch panel during map display.

  In the setting screen illustrated in FIG. 2, when “move to center” is selected and set, the controller 10 </ b> A is pressed when a short press of an arbitrary part of the touch panel is detected during map display. Scroll the map so that the point is centered on the screen. On the other hand, when “enlarged map display” is selected and set, various controls for displaying an enlarged map to be described later are performed. In addition, although demonstrated as a short press, if it does not overlap with the other function which concerns on the navigation apparatus 1 not only in this, it is also possible to implement | achieve by a long press and a multiple press. Of course, selection and setting may be made not only by touch panel input but also by voice input or remote controller input.

  Next, the display example shown in FIGS. 3A to 3C shows an enlarged display method of the map displayed on the display unit 14 when the “enlarged map display” shown in FIG. 2 is selected / set. This will be explained based on this.

  3A to 3C are schematic views showing display examples of the map enlargement display method of the first embodiment. FIG. 3A shows an example of a map displayed on the display unit 14, and 3 a is a map image displayed on the full display screen of the display unit 14, and is hereinafter referred to as a “main map”. Reference numeral 3b represents a finger touched by the user, and the contact point is indicated by an x mark indicated by 3c (the x mark is not actually displayed). For simplification, other displays such as character information and landmark information are omitted.

  When the user touches, a circular enlarged view 3d as shown in FIG. 3B is displayed. In addition, although the enlarged view 3d is circular, it is not limited to a circle but may be an ellipse or a polygon such as a quadrangle. Moreover, the detailed map displayed inside the enlarged view may be displayed transparently and displayed simultaneously with the main map.

  Next, when a slide movement of the finger from the contact point by the user (for example, an action as indicated by a broken line arrow in FIG. 3C) is detected, an enlarged view 3d (a broken line circle in FIG. 3C) Is slid in synchronization with the position of the finger, and an enlarged view 3f is displayed. During the movement from the enlarged view 3d to 3f, the detailed map in the enlarged view may be updated at a certain interval according to the position of the enlarged view on the main map, or the completion of the slide movement is detected. You may update only when. 3g is a finger after sliding movement. The broken line is not actually displayed.

  Next, the positional relationship between the position of the user's finger shown in FIG. 3B and the enlarged view will be described in detail with reference to FIG.

  FIG. 4 is a schematic diagram showing the positional relationship between the position of the user's finger and the enlarged view. 4, 4a is an enlarged view, 4b is a display center of the enlarged view, 4c is a user's finger, 4d is a finger pressing point, and 4e is a distance from the upper end of the enlarged view to the finger pressing point. 4f is the distance from the lower end of the enlarged view to the finger pressing point. As shown in FIG. 4, the enlarged view is displayed so that the display center 4b of the enlarged view comes above the finger pressing point 4d. For example, the ratio of 4e and 4f is set to 5: 1 (this ratio may be changed through a setting screen (not shown) displayed on the display unit 14). Thereby, the user can visually recognize the enlarged view without being obstructed by the hand or the finger as compared with the enlarged view display in which the display center 4b of the enlarged view and the finger pressing point 4d are matched.

  Next, operation | movement of 10 A of control parts in the navigation apparatus 1 which concerns on this Embodiment 1 is demonstrated with reference to FIGS.

  FIG. 5 is an operation flowchart showing an operation from pressing an arbitrary point on the main map to displaying an enlarged view. This processing operation is executed when the enlarged view display mode is set.

  First, the standby state is maintained until an arbitrary point on the main map is touched (S10 and S11: No). If an arbitrary point on the touch panel is pressed while displaying the main map (S11: Yes), the process proceeds to step S12. In step S12, the area of the enlarged view (the circular size shown in FIG. 3B) is acquired, the display center (4b in FIG. 4) is calculated, and the coordinate value of the display center is acquired. The coordinate value is a normalized coordinate value (vertical XH × horizontal YH) that is a coordinate value managed in a normal map. Since the normalized coordinates are described in detail in Patent Document 1, description thereof is omitted. Next, in step S13, the scale of the enlarged view is acquired. Then, the enlarged view is displayed superimposed on the main map (S14).

  In addition, regarding the acquisition of the area of the enlarged view and the acquisition of the scale described in steps S12 and S13 in the operation flow diagram of FIG. 5, the area and scale set and stored in a memory (not shown) or the like in advance through a setting screen described later. It is desirable to obtain by referring to.

  Next, an example of a screen for setting a region and scale of an enlarged view will be described with reference to FIGS. The user can freely select and set the area and scale of the enlarged view through the setting screens shown in FIGS.

  FIG. 7 is a schematic diagram showing an example of an enlarged view display setting screen that is displayed on the display unit 14 and allows the user to select whether to set an enlarged view area or a reduced scale. Here, when “enlarged area setting” is selected, the control unit 10A displays the enlarged area setting screen shown in FIG. 8, and when “enlarged scale setting” is selected, the enlarged area shown in FIG. The figure scale setting screen is displayed.

  FIG. 8 is a schematic diagram illustrating an example of an enlarged view area setting screen that allows an enlarged view area to be freely selected and set. As shown in FIG. 8, the area of the enlarged view can be selected and set in three stages, “large”, “medium”, and “small”. FIG. 8A shows a state where “large” is selected, FIG. 8B shows a state where “medium” is selected, and FIG. 8C shows a state where “small” is selected. . The user can set the area of the enlarged view shown in FIG. 3B and store it in the memory by pressing the setting button. In FIG. 8, the area has been described as having three levels of “large”, “medium”, and “small”. However, the present invention is not limited to this, and continuous area setting using a slide bar or the like is not limited to this. You may be able to do it. In FIG. 8, the area shape of the enlarged view is a circle, but may be a polygon such as an ellipse or a quadrangle, or an arbitrary shape.

  FIG. 9 is a schematic diagram illustrating an example of an enlarged view area setting screen that allows a user to freely select and set the scale of the enlarged view. In FIG. 9, to simplify the description, it is assumed that the map information storage unit 11 stores a map of five scales. Here, the scale of the enlarged map can be set according to each of the five scales of the main map. FIG. 9A is a schematic diagram showing that the scale of the enlarged map is switched in four stages when the scale of the main map is the widest area (currently, the scale of the second widest area is selected). Status). In addition, an enlarged view with the same scale as the current scale cannot be displayed (the hatched line represents tone down). FIG. 9B is a schematic diagram showing that the scale of the enlarged map is switched in two stages when the scale of the main map is the middle (third) (currently, the second most detailed scale is selected). State). In addition, an enlarged view with a scale that is the same as the current scale or a wide scale cannot be displayed (shaded lines indicate tone down). FIG. 9C is a schematic diagram showing that the scale of the enlarged map is switched at the 0 stage when the scale of the main map is the most detailed (state in which the enlarged map cannot be selected). Since the scale of the main map is the most detailed, no more detailed enlarged view can be displayed, so all the scale settings of the enlarged view are toned down. As described above, when the scale of the main map is the most detailed, it is desirable that the enlarged map display performed in step S14 in the operation flowchart of FIG. 5 is not displayed as an exception.

  In the above description, it has been shown that the user can freely select and set the area setting and scale setting of the enlarged view. However, the present invention is not limited to this, and the control unit 10A automates and arbitrarily sets the area and scale of the enlarged view. May be set. Regarding the setting of the area of the enlarged view, the size of the circle can be freely changed according to the place. For example, in an area where the density of buildings is high (for example, an urban area), the size of the circle in the enlarged view can be increased, and the size of the circle can be reduced as the density is reduced. In another embodiment, the size of the circle in the enlarged view can be freely changed according to the scale of the main map. For example, when the main map is displaying a wide area map, the size of the circle in the enlarged view can be increased, and the size of the circle can be reduced as the details become more detailed. On the other hand, regarding the setting of the scale of the enlarged view, for example, the scale to be displayed on the enlarged view can be fixedly set like a map that is one step more detailed than the scale to be displayed on the main map.

  Next, the description of the operation of the control unit 10A in the navigation device 1 according to the first embodiment will continue returning to FIG.

  FIG. 6 is an operation flowchart showing an operation when an instruction is given from the user while an enlarged view is displayed (a state where the finger is also pressed is continued). This processing operation is processing after (A) in FIG. FIG. 6A is an operation flowchart showing that the enlarged view is also moved in synchronization with the slide of the finger during the enlarged view display. First, it is determined whether there is a slide movement from the pressed point (S15). If there is no slide movement, the process returns to (A) again (S15: No). On the other hand, when slide movement is detected (S15: Yes), the process proceeds to step S16. In step S16, the enlarged view is moved in synchronization with the finger slide. Next, the processing after (C) in FIG. 5 is performed, and the enlarged view of the tip of the finger slide is displayed in the same manner. With this operation flow, the enlarged view shown in FIG. 3C can be displayed. Note that, after step S16, a determination process as to whether the finger slide has stopped may be inserted. By doing so, it is possible to refrain from updating the drawing while the finger is sliding, and the processing load on the control unit 10A can be suppressed.

  FIG. 6B is an operation flowchart showing the operation when the finger is released during the enlarged view display. First, it is determined whether or not the finger is released (S17). If the finger is not released (S17: No), the process returns to (A) again (S17: No). On the other hand, if it is detected that the finger has been released (S17: Yes), the process proceeds to step S18. In step S18, the enlarged view is deleted, that is, the enlarged view is not displayed on the main map.

  With the navigation device according to the first embodiment described above, even if there are a plurality of arbitrary points that are desired to be enlarged, after the finger is pressed to display an enlarged view, the enlarged view is also displayed as a finger by sliding the finger. Since they move synchronously, it is possible to realize a map display device that is convenient for the user and has a low operation load.

(Embodiment 2)
Next, the map display apparatus according to the second embodiment will be specifically described with reference to the drawings. As in the first embodiment, a case where the map display device of the present embodiment is applied to a navigation device will be described as an example. However, since the configuration of the navigation device is the same as the configuration of the navigation device shown in FIG. 1 except for the control unit 10, the control unit 10 is denoted by a different reference numeral (10B), and the other description will be given here. Omitted. The same applies to FIGS. 2 and 7 to 9 regarding various setting screens, and a description thereof will be omitted.

  First, the map enlarged display method displayed on the display unit 14 when the “enlarged map display” shown in FIG. 2 is selected and set is based on the display examples shown in FIGS. explain.

  FIGS. 10A and 10B are schematic views showing display examples of the enlarged view display method of the second embodiment. FIG. 10A shows an example of a map displayed on the display unit 14, and 10 a is a map image displayed on the full display screen of the display unit 14, and is hereinafter referred to as a “main map”. Reference numeral 10b represents a finger touched by the user, and the contact point is indicated by an x mark indicated by 10c (the x mark is not actually displayed). For simplification, other displays such as character information and landmark information are omitted.

  When the user touches, a circular enlarged view 10d as shown in FIG. 10B is displayed around the contact point. In addition, although the enlarged view 10d is circular, it is not limited to a circle but may be an ellipse or a polygon such as a quadrangle. Moreover, the detailed map displayed inside the enlarged view may be displayed transparently and displayed simultaneously with the main map.

  Next, operation | movement of the control part 10B in the navigation apparatus 1 which concerns on this Embodiment 2 is demonstrated with reference to FIGS.

  FIG. 11 is an operation flowchart showing an operation from pressing an arbitrary point on the main map to displaying an enlarged view. This processing operation is executed when the enlarged view display mode is set. The enlarged view display processing operation has a configuration in which step S20 is inserted instead of step S12 in FIG. 5, and only the differences will be described below.

  First, the standby state is maintained until an arbitrary point on the main map is touched (S10 and S11: No). If an arbitrary point on the touch panel is pressed while the main map is displayed (S11: Yes), the process proceeds to step S20. In step S20, the area of the enlarged view (the circular size shown in FIG. 10B) is acquired, the display center (10c in FIG. 10A) is calculated, and the coordinate value of the display center is acquired. In the first embodiment, the enlarged view is not displayed centering on the place where the user presses the finger, but in the second embodiment, the enlarged view is not erased even if the user's finger is released. Since the subsequent operation is continued, it is easy to obtain an enlarged view intended by the user, and therefore it is desirable to display the enlarged view with the pressed position as the display center.

  Next, an operation when the user's finger is released will be described with reference to FIG. This processing operation is processing after (D) in FIG. In addition, step S21 is inserted instead of step S18 in FIG. 6B.

  FIG. 12 is an operation flowchart showing an operation when the finger is released during the enlarged view display. First, it is determined whether or not the finger is released (S17). If the finger is not released (S17: No), the process returns to (D) again (S17: No). On the other hand, if it is detected that the finger has been released (S17: Yes), the process proceeds to step S21. In step S21, the display of the enlarged view is continued. That is, the difference from FIG. 6B is that the enlarged view is not erased even when the user's finger is released.

  Next, in the case where there is a finger contact after (F) in FIG. 12, the control unit 10 </ b> B is displayed in a wide scale and an enlarged view displayed on the main map according to a place where the enlarged view is touched. A display example (FIGS. 13, 15, and 18) indicating that different controls are performed based on the detailed scale and its operation flow (FIGS. 14, 16, 17, and 19) will be described in detail.

  First, a display example and its operation flow when a wide area control area (an area for the control unit 10B to perform control in consideration of a wide scale) in the enlarged view is touched will be described with reference to FIGS. .

  FIGS. 13A and 13B are schematic diagrams illustrating a display example when the wide area control area in the enlarged view is touched. FIG. 13 shows display examples after FIG. FIG. 13A shows an example of a case where the user has touched the wide area control area in the enlarged view, and here shows a state where the outer frame 13a of the enlarged view is touched as the wide area control area. (The x mark is not actually displayed.) Next, when a slide movement of a finger (for example, an action as indicated by a broken line arrow in FIG. 13B) is detected in a state where the wide control area is touched, a broken line in the enlarged view 13b (FIG. 13B). The circle) slides in synchronization with the position of the finger, and an enlarged view 13c is displayed. Reference numeral 13d denotes a finger after the slide movement. The broken line is not actually displayed.

  Next, the operation when the wide area control area in the enlarged view is touched will be described with reference to FIG.

  FIG. 14 is an operation flowchart showing an operation when the wide area control area in the enlarged view is touched. Note that the operation flow of FIG. 14 shows the operation after (F) in FIG.

  First, in step S22, it is determined whether the wide area control area (enlarged view outer frame) of the enlarged view has been pressed. If not pressed (S22: No), the process returns to (F) again. On the other hand, when the wide area control area is pressed (S22: Yes), the process proceeds to the next step S23. In step S23, it is detected whether a slide movement from the pressed point has occurred. If no slide movement has occurred (S23: No), the process returns to (F) again. On the other hand, if the occurrence of slide movement is detected (S23: Yes), the process proceeds to the next step S24. In step S24, the enlarged view is moved in synchronization with the finger slide. Next, the area of the enlarged view is acquired, the display center is calculated, and the coordinate value is acquired (S25). The display center position can be uniquely determined by the position of the finger touching the outer frame of the enlarged view and the size of the area. The coordinate value is a normalized coordinate. Next, in step S26, the scale of the enlarged view is acquired. Then, an enlarged view is displayed (S27). With this operation flow, the enlarged view shown in FIG. 13B can be displayed. In addition, after step S24, a determination process as to whether the finger slide has stopped may be inserted. In this way, it is possible to refrain from updating the drawing while the finger is sliding, and the processing load on the control unit 10B can be reduced.

  Next, with reference to FIG. 15 and FIG. 16, a display example and its operation flow when a detailed control area in the enlarged view (an area for the control unit 10B to perform control in consideration of the detailed scale) is touched will be described. To do.

  FIGS. 15A to 15C are schematic diagrams illustrating display examples when the detailed control area in the enlarged view is touched. FIG. 15 shows display examples after FIG. FIG. 15A shows an example when the user touches the detailed control area in the enlarged view, and here shows a state where the inside 15a of the enlarged view is touched as the detailed control area. (The x mark is not actually displayed.) Next, when a slide movement of a finger (for example, an action as indicated by a broken line arrow in FIG. 15B) is detected while the detailed control area is touched, an enlarged view 15c (a solid line in FIG. 15B). Circle) The internal display slides in synchronism with the sliding movement of the finger and changes to an enlarged view 15c. Reference numeral 15d denotes a finger after the slide movement. The broken line arrow is not actually displayed. Next, in the state of FIG. 15B, the coordinate value at the display center of the enlarged view does not match the coordinate value displaying the enlarged view with respect to the main map, so as shown in FIG. Move the enlarged view by the amount and direction indicated by the dashed arrows. In FIG.15 (c), 15e is an enlarged view after a movement, a broken-line circle is an enlarged view before a movement, and the position corresponds with 15c in FIG.15 (b). The dashed line is not actually displayed. The enlarged view may be moved in synchronization with the finger slide movement, or the enlarged view may be moved after detecting that the finger is released.

  Next, returning to FIG. 15 (a), another example when the user touches the detailed control area in the enlarged view will be described.

  As in the previous case, FIG. 15A shows a state in which the inside 15a of the enlarged view is touched as the detailed control area (the x mark is not actually displayed). Next, when the detailed control area is touched and the finger is held without sliding (finger indicated by a broken line 15f in FIG. 15B), as shown in FIG. 15B. The detailed map inside the enlarged view scrolls so that the touched position in the detailed control area is at the center. The broken line arrows indicate the scroll amount and direction, and are not actually displayed. Reference numeral 15d denotes a finger after the slide movement, which is not relevant in this example. Next, as before, the position of the enlarged view with respect to the main map is fixed at this point. In the state of FIG. 15B, since the coordinate value at the display center of the enlarged view and the coordinate value displaying the enlarged view with respect to the main map do not match, the enlarged view is displayed as shown in FIG. Move by the amount and direction indicated by the dashed arrows. In FIG.15 (c), 15e is an enlarged view after a movement, a broken-line circle is an enlarged view before a movement, and the position corresponds with 15c in FIG.15 (b). The enlarged view may be moved in synchronization with the scrolling of the detailed map inside the enlarged view, or the enlarged view may be moved after detecting that the finger is released. In the former case, the state of FIG. 15B does not exist, and the screen transitions from FIG. 15A to FIG. 15C. The broken line is not actually displayed.

  Next, the operation when the detailed control area in the enlarged view is touched will be described with reference to FIG.

  FIG. 16 is an operation flowchart showing an operation when the detailed control area in the enlarged view is touched. Note that the operation flow of FIG. 16 shows the operation after (F) in FIG.

  First, in step S28, it is determined whether or not the detailed control area (detailed map inside the enlarged view) of the enlarged view has been pressed. If not pressed (S28: No), the process returns to (F) again. On the other hand, when the detailed control area is pressed (S28: Yes), the process proceeds to the next step S29. In step S29, the detailed map synchronized with the slide movement of the finger (movement from the finger 15f before sliding to the finger 15d after sliding in FIG. 15) or the center of the pressed point (the fingers 15a and 15f in FIG. 15). The position is the same and is held down.) Display the detailed map. At this time, the position of the enlarged view with respect to the main map may be fixed, or may be moved in synchronization with the scroll. Next, when the position of the enlarged map with respect to the main map is fixed in step S29, the process proceeds to step S30, and the enlarged map is moved so that the display centers of the main map and the detailed map inside the enlarged map are matched. After the enlarged view is displayed, the process returns to (D) of FIG. With this operation flow, the enlarged view shown in FIG. 15C can be displayed.
