(Outline configuration of map presentation device)
FIG. 3 is a schematic diagram illustrating a schematic configuration of the map presentation device 100 according to the present embodiment. Hereinafter, a description will be given with reference to FIG.
The map presenting apparatus 100 includes a storage unit 110, a position detection unit 120, an operation reception unit 130, a display control unit 140, and a display unit 150.

The storage unit 110 stores map data in which a plurality of target positions (for example, store positions) are set.
For example, the storage unit 110 stores map data including store information 111 as shown in FIG. Note that the map data is created in a GIS (Geographic Information System) format as an example, and icons (various icons) indicating stores are superimposed on store locations on the map.
The store information 111 illustrated in FIG. 4 includes a store ID 111a, a store type 111b, an icon ID 111c, and a store position 111d (latitude, longitude).
The above-described flash memory 11, WRAM 10e, and the like can function as such a storage unit 110.

Returning to FIG. 3, the position detection unit 120 detects the current position of the map presentation device 100. For example, the position detection unit 120 detects the current position by generating position information including latitude and longitude indicating the current position.
The positioning unit 19 described above can function as such a position detection unit 120.

The operation reception unit 130 receives various operations from the user. For example, the operation reception unit 130 receives an operation from the user based on the information obtained from the touch screen 18 described above. For example, the operation reception unit 130 receives a scroll instruction for the map image in response to a flick operation by the user.
The CPU core 10a, the touch screen controller 10g, and the like described above can function as such an operation receiving unit 130.

The display control unit 140 sets the reference position and scale of the map image displayed on the screen so that at least one of the plurality of store positions is displayed in the screen (in the display area of the display unit 150).
For example, the display control unit 140 sets the current position detected by the position detection unit 120 as the reference position (for example, the center position of the map image to be displayed) on the initial screen (initial screen when displaying the map image). A predetermined initial value (initial scale) is set as the scale. Note that the display is performed when none of the store positions 111d shown in FIG. 4 is included in the map image determined by the reference position and scale set in this way (that is, the range of the map displayed on the display unit 150). The control unit 140 reduces the scale one step at a time (increases the range) so that at least one of the store positions 111d is included in the map image.
The reference position set on the initial screen is not limited to such a current position, and can be changed as appropriate. For example, the position of a landmark designated by the user (for example, a station or a facility) may be set as the reference position.
A map image determined from the reference position and scale set in this way is displayed on the display unit 150.

  In addition, when the display control unit 140 receives a scroll instruction from the user in the operation reception unit 130, if there are a plurality of store positions displayed on the screen, the map image is moved according to the scroll instruction. Update the reference position. On the other hand, if there is one store position displayed on the screen, the display control unit 140 updates the scale so that the map image is reduced according to the scroll instruction.

  As a specific example, as shown in FIG. 5 (a), in a state where two icons (icons i1, i2) are displayed on the display unit 150 on the map image (a state where there are a plurality of store positions in the screen), A case where the user performs a flick operation in the arrow direction (horizontal direction from right to left) will be described. It is assumed that the user repeatedly performs such a flick operation and sequentially issues a scroll instruction in the arrow direction.

  In this case, since there are a plurality of store positions in the screen, the display control unit 140 updates the reference position so that the map image moves to the left in accordance with the scroll instruction (updates sequentially). As a result, the map image displayed on the display unit 150 scrolls to the left as shown in FIG. Eventually, as shown in FIG. 6A, when the store position of the icon i1 is not included in the screen and only the icon i2 is present, the display control unit 140 scrolls because the store position in the screen is one. The scale is updated (updated sequentially) so that the map image is reduced according to the instruction. As a result, the map image displayed on the display unit 150 is sequentially reduced as shown in FIGS.

  Then, as shown in FIG. 6C, when the store positions of the icons i3 and i4 are added to the screen, there are a plurality of store positions (three icons i2 to i4) in the screen. Updates the reference position so that the map image moves to the left in response to the scroll instruction (updates sequentially).

  Note that the image processing unit 10b and the LCD controller 10f described above can function as such a display control unit 140.

Returning to FIG. 3, the display unit 150 displays a map image or the like. That is, the display unit 150 displays a map image determined by the reference position and scale set by the display control unit 140.
Note that the display device 17 described above can function as such a display unit 150.

(Outline of operation of map presentation device)
Hereinafter, the operation of the map presenting apparatus 100 having such a configuration will be described with reference to the drawings. As an example, the operation of the map presentation device 100 in a state where the map image of FIG. 5A described above is displayed on the display unit 150 will be described with reference to FIG.
FIG. 7 is a flowchart showing a flow of map presentation processing executed by the map presentation device 100.

First, the map presentation device 100 determines whether or not a flick operation on the touch screen 18 has been detected (step S201).
That is, the operation accepting unit 130 determines whether or not a flick operation with a finger or the like has been accepted and a scroll instruction has been given from the user.
If it is determined that the flick operation on the touch screen 18 is not detected (step S201; No), the map presenting apparatus 100 waits for detection of the flick operation as it is.

On the other hand, if it is determined that a flick operation on the touch screen 18 has been detected (step S201; Yes), the map presentation device 100 determines whether there are a plurality of store positions in the screen (step S202).
That is, the display control unit 140 determines whether or not a plurality of store icons are displayed in the map image of FIG.

When it is determined that there are a plurality of store positions on the screen (step S202; Yes), the map presentation device 100 switches to the reference position update mode (step S203).
That is, the display control unit 140 switches to the reference position update mode in which the reference position of the map image is updated according to the scroll instruction. If already in the reference position update mode, the reference position update mode is continued as it is.

The map presentation device 100 updates the reference position so that the map image moves (step S204).
For example, as shown in FIG. 5A described above, when a flick operation is performed in the arrow direction (horizontal direction from right to left), the display control unit 140 moves the map image to the left according to the scroll instruction. Update the reference position to move. As a result, the map image displayed on the display unit 150 scrolls to the left as shown in FIG.

On the other hand, when it is determined in step S202 that there are not a plurality of store positions in the screen (only one) (step S202; No), the map presentation device 100 switches to the scale update mode (step S205).
That is, the display control unit 140 switches to a scale update mode in which the scale of the map image is updated according to the scroll instruction. If already in the scale update mode, the scale update mode is continued as it is.

The map presentation apparatus 100 updates the scale so that the map image is reduced (step S206).
For example, as illustrated in FIG. 6A described above, when the flick operation (flick operation from right to left) is continuously performed in a state where only the store position of the icon i2 is displayed, the display control unit 140 updates the scale so that the map image is reduced according to the scroll instruction. As a result, the map image displayed on the display unit 150 is sequentially reduced as shown in FIGS. 6B and 6C described above.

  Then, as shown in FIG. 6C, when the store positions of the icons i3 and i4 are added to the screen, the store positions in the screen become a plurality (three icons i2 to i4). To switch to the reference position update mode, and the reference position is updated in step S204 described above, and the map image is scrolled.

By such map presentation processing, at least one store icon as a target position is continuously displayed even when scrolling. For this reason, the user can search for nearby stores without losing sight of the target position.
As a result, a map image including the target position can be appropriately presented.

(Other embodiments)
In the above embodiment, as shown in FIG. 6A described above, the map image is reduced (switched to the scale update mode) when the store position on the screen becomes one (only the icon i2). However, it may be switched to the scale update mode in response to the movement of the single store position to the peripheral area of the screen.

That is, as shown in FIG. 6A described above, the display control unit 140 continues to update the reference position in response to the scroll instruction even when the number of store positions in the screen becomes one (only the icon i2). Eventually, as shown in FIG. 8A, when the store position of the icon i2 moves to the peripheral area in the screen, the display control unit 140 switches to the scale update mode as a trigger. That is, the display control unit 140 updates the scale so that the map image is reduced according to the scroll instruction. As a result, the map image displayed on the display unit 150 is sequentially reduced as shown in FIGS.
Then, as shown in FIG. 8C, when the store positions of the icons i3 and i4 are added to the screen, the store positions in the screen are plural (three icons i2 to i4). Switches to the reference position update mode in the same manner as described above.

  In the above embodiment, the case where the map image is moved (switched to the reference position update mode) when the store position in the screen is increased from one to plural has been described. (For example, 2, 3, 5, etc.) When the threshold value is exceeded from the following, it may be switched to the reference position update mode.

  In the above embodiment, the case where the current screen is used as a reference and the mode is switched to the reference position update mode or the scale update mode according to the change in the number of store positions has been described. You may switch to the reference position update mode or the scale update mode according to a change in the number of store positions, with the inside of the screen after being moved as a reference.

  In the above embodiment, the case where the store position is set in the map data as the target position has been described, but the target position is not limited to such a store position and is arbitrary. For example, even when the position of the user's home where the product is to be delivered is set as the target position in the map data, a map image including the target position can be appropriately presented as described above.

  In the above embodiment, the case where the scroll instruction is performed by the flick operation using the smartphone 1 has been described, but the scroll instruction may be performed by another method. For example, even when the user gives a scroll instruction by rotating the trackball in an arbitrary direction using a trackball of a personal computer, a map image including the target position can be appropriately presented as described above. .
