[Main Processing in Map Information Display Device]
In step 402 (hereinafter, step is abbreviated as S),
The CPU 116 reads data from the storage device 104 and stores it in the temporary storage device 118.

At S500, map data preparation processing is executed. The map data preparation process is a process of converting the position data into coordinate data based on the information read into the temporary storage device 118. Details of the process of S500 will be described later. When the process of S500 ends, the coordinate data of all the icons and the number of icons displayed in the icon area 122 are calculated.

At S404, CPU 116 causes S500.
It is determined whether or not the number of icons included in the icon area 122 calculated in step 0 is zero. Icon area 12
If the number of icons included in 2 is 0 (YES in S404), the process proceeds to S406. Icon area 12
If the number of icons included in 2 is not 0 (NO in S404), the process proceeds to S408.

In S406, CPU 116 determines whether or not the setting for displaying icon area 122 in the display state is valid. When the setting for setting the icon area 122 to the display state is valid (YES in S406)
S), the process proceeds to S408. When the setting for displaying the icon area 122 is not valid (S406
NO), the process proceeds to S410.

At S408, CPU 116 instructs display device 102 to display map area 120 and icon area 122. In the map area 120, the map information and the icon whose position is specified based on the coordinate data are displayed. If there is no icon specified based on the coordinate data (YES in S406),
The icon area 122 is blank. If there is an icon specified based on the coordinate data (S404
No), the icon is displayed. Since the icons displayed in the icon area 122 include coordinate data unique to each icon, even when the number of icons included in the icon area 122 is plural, no icons are displayed in an overlapping manner. When all icons are displayed,
The process proceeds to S412.

At S410, CPU 116 instructs display device 102 to display map information and the icon whose position is specified based on the coordinate data in map area 120. The icon area 122 is not displayed. The process proceeds to S412.

At S412, CPU 116 determines whether or not there is an icon whose position data has been updated. If there is an icon with updated position data (YES in S412), the process proceeds to S500. In this case, S50
After 0 is completed, either of the map area 120 and the icon area 122 is displayed in either of S408 and S410. As a result, the icon area 122
Even if is not displayed, the icon area 122 is switched to the displayed state when the position data is updated. If there is no icon with updated position data (S
(NO in 412), and the process proceeds to S414.

At S414, CPU 116 determines whether or not a predetermined time has elapsed since the position data was last updated. When the predetermined time has elapsed (S4
(YES in 14), and the process proceeds to S416. If the predetermined time has not elapsed (NO in S414), the process proceeds to S412.

At S416, CPU 116 determines whether or not icon area 122 is in a display state. When icon area 122 is in the display state (YES in S416), the process proceeds to S418. Icon area 122
When is not in the display state (NO in S416), the process proceeds to S412.

At S418, CPU 116 determines whether or not the icon area 122 has been set by the user so as to be switched to non-display after a predetermined time has elapsed. When it is set as such (S418
And YES), the process proceeds to S420. If not so set (NO in S418), the process proceeds to S42.
Move to 2.

At S420, CPU 116 instructs display device 102 to switch icon region 122 in the display state to the non-display state. As a result, the icon area 122 is switched to the non-display state when a predetermined time has elapsed since the position data was last updated.

In S422, CPU 116 determines whether or not there is a user's end instruction. When there is an instruction to end (YES in S422), all the processes related to map information display device 100 are ended. If there is no end instruction (NO in S422), the process proceeds to S412.

[Map data preparation process] Referring to FIG.
The map data preparation process in S500 of FIG. 4 will be described based on the flowchart.

At S502, CPU 116 calculates the number of icons to be processed. This number is calculated from the number of records of data stored in the temporary storage device 118.

At S504, CPU 116 displays the map information area displayed in map area 120 (for example, XY).
The position data is associated with coordinates (0,0) to (800,600). At this time, the display device 1 used to associate the position data with the map area 120
Image display area in 02 (dotted coordinates)
Is shown in FIG.

For example, for coordinates (0,0) in the map area 120, (E135.11.10, N4
2.11.10) is set, and (E135.11.15, N42.11.15) is set to (800,600). As a result, the first point at 135 degrees 11 minutes 10 seconds east longitude and 42 degrees 11 minutes 10 seconds north latitude, 135 degrees 11 east longitude
Second 10 minutes 42 degrees 11 minutes 15 seconds north latitude, 135 degrees 11 minutes 15 seconds east longitude third point 42 degrees 11 minutes 10 seconds north latitude
Point, 135 ° E11'15'E, 42N
The area surrounded by the fourth point at 11 minutes and 15 seconds is defined as the initial value of the map area 120. In this case, east longitude and north latitude are used, but the same applies to west longitude and south latitude.

The CPU 116 calculates a conversion value (for example, α in the x coordinate direction and β in the y coordinate direction) between the distance on the map information and the distance on the display screen. For example,
There is such a relation that the length of 1 second in longitude is 2 dots on the display screen (α = 2). This is also the case for a length of 1 second in latitude.

At S506, CPU 116 initializes the counter. The first counter calculates the number of icons for which conversion data calculation processing, which will be described later, has been completed. The second counter counts the number of icons included in the icon area 122.

At S508, CPU 116 reads the data stored in temporary storage device 118. After that, the process proceeds to the conversion data calculation process (S700).

In step S700, coordinate data is calculated based on the position data. The icon of which the position on the map information is specified includes the coordinates indicating the specified position in the coordinate data. The icon whose position is not specified includes a value calculated based on a pseudo data calculation logic described later. Details of the processing in S700 will be described later.

At S510, CPU 116 writes the calculated coordinate data in temporary storage device 118.

At S512, CPU 116 increments the value of the first counter by 1 in response to the completion of the conversion process for one icon.

At S514, CPU 116 determines whether or not the conversion data calculation processing for all icons has been completed. When the conversion data calculation process for all the icons is completed (YES in S514), the process ends and the process returns to S500. If the conversion data calculation process for all the icons is not completed (NO in S514), the process proceeds to S700 and the conversion data calculation process is continued.

[Conversion data calculation process] Referring to FIG.
The conversion data calculation process in S700 of FIG. 5 will be described based on the flowchart.

In S702, CPU 116 determines whether or not the position data of the icon stored in position data storage area 206 is Null. If the position data of the icon is Null (YES in S702), the process proceeds to S706. When the position data of the icon is not Null (NO in S702), the process proceeds to S704.

At S704, CPU 116 converts the icon position data into coordinate data on the map information. The conversion logic at this time is as follows, for example.

The CPU 116 calculates the difference ΔX in the x coordinate and the difference ΔY in the y coordinate on the basis of the coordinates of the first point on the map information and the coordinates of the icon defined in S504. For example, the first point (origin)
Position data of E135.11.10 and position data of the nth icon is E135.11.13, ΔX
Is (13-10 =) 3 (seconds). The value αΔX obtained by multiplying α representing the number of dots per second by ΔX is the map area 1
It becomes the value of the x coordinate of the icon in 20. Similarly, the value βΔY obtained by multiplying β by ΔY becomes the value of the y coordinate of the icon in the map area 120. The CPU 116 stores the calculated coordinate data in the temporary storage device 118.

In S706, the CPU 116 gives the pseudo data to the coordinate data of the icon whose position data is Null based on the pseudo data calculation logic. At this time, the CPU 116 gives 0 to the x coordinate of the coordinate data and gives the value of the second counter to the y coordinate. The value of this counter is a unique value for each icon whose position data is Null. Therefore, the y-coordinate value of the coordinate data of the icon displayed in the icon area 122 is also a unique value.

In S708, CPU 116 increments the value of the second counter by 1 in response to the completion of the conversion process of the icons contained in icon area 122, and then the process proceeds to S700.

The operation of the map information display device 100 according to the present embodiment based on the above structure and flowchart will be described.

When the user activates the map information display device 100, the control device 106 reads the data necessary for the map information display processing from the storage device 104 (S402),
The data is written to the temporary storage device 118.

The control device 106 starts the map data preparation process based on the data written in the temporary storage device 118 (S500). The control device 106 calculates the number of icons to be processed (S502). Control device 106
Associates an initial value (for example, longitude, latitude) of preset position data with the map area 120 (S50
4).

The control device 106 reads the data from the temporary storage device 118 and executes the conversion data calculation process (S700). The control device 106 controls the number of icons,
When the conversion data calculation process is executed and the processes of all the icons are completed (YES in S514), the map data preparation process is ended and the process returns to the main process.

When the coordinate data of all the icons are calculated, the control device 106 determines whether the number of icons included in the icon area 122 is 0 (S40).
4).

When the number of icons included in icon area 122 is 0 (YES in S404), the setting for putting icon area 122 in the display state is valid by the user (in S406). Control unit 106 controls the map area 120 and the icon area 12
The display device 102 is instructed to display 2 (S408). FIG. 8 shows a state in which the map area 120 and the blank icon area 122 are displayed.

On the other hand, when the number of icons included in icon area 122 is 0 (YES in S404), the setting for putting icon area 122 in the display state is not valid by the user (( N in S406
O), the control device 106 instructs the display device 102 to display only the map area 120 (S41).
0). FIG. 9 shows a state in which only the map area 120 is displayed. In this case, the icon area 122 is in a non-display state.

When the number of icons included in icon area 122 is not 0 (NO in S404), control device 10
6 instructs the display device 102 to display the map area 120 and the icon area 122 (S40).
8). FIG. 10 shows a map area 120 and an icon area 1.
22 shows the displayed state. The icon whose position on the map information is specified is displayed so as to be superimposed on the map information based on the coordinate data calculated from the position data. The icon whose position on the map information is not specified is displayed in the icon area 122 based on the coordinate data provided with the pseudo data.

Map area 120 and icon area 122
When the display of one of the areas is completed, the control device 106
Determines whether there is an icon whose position data has been updated (S412).

When there is an icon whose position data has been updated (YES in S412), control device 106 calculates coordinate data based on the updated position data (S).
500). When there is no icon whose position data has been updated (NO in S412), control device 106 compares the time elapsed after the display of the icon is completed with a predetermined display time (S414).

When the elapsed time is shorter than the display time (NO in S414), control device 106 continues to determine whether or not there is an icon whose position data has been updated (S412). When the elapsed time exceeds the display time (YES in S414), control device 106
Confirms the display state of the icon area 122 (S4).
16).

If the setting that the icon area 122 is automatically switched to the non-display state when the icon area 122 is in the display state (YES in S416) is valid by the user (YES in S418). ), The control device 106 switches the icon area 122 to the non-display state (S420). If the setting is not valid (NO in S418), control device 106 determines whether or not there is an instruction to end the map information display device from the user (S422). When there is no end instruction (NO in S422), control device 106 continues to determine whether the position data has been updated (S412).

When there is an end instruction (YE at S422)
S), the control device 106 ends the execution of the program by the map information display device 100.

As described above, the map information display device
Based on the stored position data, the icon whose position on the map information cannot be specified can be displayed without duplication. When the position data of the icon is updated, the display position of the icon can be changed between the region displaying the icon and the map information and the region displaying only the icon based on the updated position data. If the user has enabled the setting for switching the area displaying only the icon to the non-display state when the predetermined time has passed the preset display time, the area becomes the non-display state. Can be switched. As a result, it is possible to provide a map information display device that can centrally manage information about icons and improve the utilization of the information by the user even if the information for controlling the icons is missing.

When the number of icons included in the icon area 122 is 0, the setting of the icon area 122 may be fixed in advance so that the icon area 122 is hidden. As a result, the icon area 122
When the number of icons included in the icon is 0, the process of displaying the icon area 122 can be omitted. As a result, the processing time in the main processing can be shortened.

The embodiments disclosed this time must be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above description but by the claims, and is intended to include meanings equivalent to the claims and all modifications within the scope.
