[First Embodiment]
First, a first embodiment of the present invention will be described. FIG. 1 is a schematic diagram showing a configuration of a display system 1 in the present embodiment. The display system 1 is for grasping the process of altitude change on the map, and includes an electronic timepiece 100 and an electronic device 200. The electronic timepiece 100 is an electronic timepiece with an altitude measuring function that measures altitude by atmospheric pressure. The electronic device 200 is an electronic device with a GPS function, such as a smartphone or a tablet terminal. The electronic timepiece 100 and the electronic device 200 communicate with each other by short-range wireless communication such as Bluetooth (registered trademark).

  The electronic timepiece 100 transmits altitude information regarding the measured altitude to the electronic device 200. The electronic device 200 shows a map of altitude change on a map based on altitude information received from the electronic timepiece 100, latitude / longitude information (position information) acquired by GPS, and map information stored in advance. The image G is displayed.

  FIG. 2 is a block diagram illustrating a configuration of the electronic timepiece 100 according to the present embodiment. In the illustrated example, the electronic timepiece 100 includes a CPU (Central Processing Unit) 101, an oscillation circuit 102, a frequency dividing circuit 103, a key input unit 104, a display unit 105, a battery 106, and an atmospheric pressure measurement unit 107. The altitude measuring unit 108, the wireless communication means 109, a RAM (Random Access Memory), and a ROM (Read Only Memory) 111 are provided.

  The CPU 101 controls each unit included in the electronic timepiece 100. Further, the CPU 101 generates altitude information from the altitude measured by the altitude measuring unit 108. Then, the CPU 101 transmits the generated altitude information to the electronic device 200 via the wireless communication unit 109. In addition, the CPU 101 has a clocking function that clocks the current time based on the measurement signal input from the frequency dividing circuit 103.

  The oscillation circuit 102 generates an oscillation signal having a predetermined frequency (for example, 32768 Hz) and outputs the oscillation signal to the frequency dividing circuit 103. The frequency dividing circuit 103 divides the frequency of the oscillation signal input from the oscillation circuit 102 to generate a measurement signal serving as a measurement reference, and outputs the generated measurement signal to the CPU 101. The key input unit 104 receives an operation input. The display unit 105 is a liquid crystal display or a segment display, for example, and displays information. The battery 106 supplies power for operation to each unit included in the electronic timepiece 100. For example, the battery 106 includes a solar cell that generates power using light received from the outside of the electronic timepiece 100 during a period in which the altitude measuring unit 108 measures altitude. Then, the battery 106 stores the power generated by the solar cell in a chargeable / dischargeable secondary battery, thereby supplying power as needed for the operation of each unit.

  The atmospheric pressure measurement unit 107 is, for example, an atmospheric pressure sensor, measures atmospheric pressure, and outputs the measured atmospheric pressure to the altitude measurement unit 108. The altitude measurement unit 108 measures the altitude based on the atmospheric pressure input from the atmospheric pressure measurement unit 107 and outputs the measured altitude to the CPU 101. The wireless communication unit 109 communicates with other devices by wireless communication.

  The RAM 110 stores data used by each unit of the electronic timepiece 100. The ROM 111 stores an operation program executed by the CPU 101 in advance. This operation program is read when the CPU 101 is activated.

  FIG. 3 is a schematic diagram illustrating an example of altitude information generated by the electronic timepiece 100 according to the present embodiment. The electronic timepiece 100 starts high-level log recording in response to an operation input accepted by the key input unit 104. The altitude log is data that associates the time measured with the altitude measured by the altitude measuring unit 108. Further, the electronic timepiece 100 ends the high-level log recording in response to the operation input accepted by the key input unit 104. Then, the electronic timepiece 100 generates altitude information indicating the recorded altitude log. As illustrated, the altitude information is an array in which time and altitude are associated with each other. In the example shown in the figure, the altitude corresponding to the time “12:00:01” is “80 m”, and the altitude corresponding to the time “12:00:31” is “77 m”.

  FIG. 4 is a block diagram illustrating a configuration of the electronic device 200 according to the present embodiment. In the example illustrated, the electronic device 200 includes a control unit 201, a display unit 202, a storage unit 203, a wireless communication unit 204, a position information acquisition unit 205, an input unit 206, and an attitude detection unit 207. .

  The control unit 201 includes a CPU and controls each unit included in the electronic device 200. In addition, the control unit 201 receives and acquires altitude information from the electronic timepiece 100 via the short-range wireless communication by Bluetooth (registered trademark) in the wireless communication unit 204. Then, the control unit 201 displays on the display unit 202 a map image that is three-dimensionally represented by the acquired altitude information, the map information stored in the storage unit 203, and the latitude / longitude information acquired by the position information acquisition unit 205. Let The map information is a map database indicating a two-dimensional map (hereinafter referred to as a two-dimensional map). The map image includes a two-dimensional map, a two-dimensional trajectory displayed on the map (first trajectory), and a three-dimensional trajectory including the height (second trajectory). The two-dimensional trajectory is a user's trajectory expressed in a planar manner based on latitude and longitude information. The three-dimensional trajectory is a user's trajectory including a height that is three-dimensionally expressed based on latitude and longitude information and altitude information. The control unit 201 causes the display unit 202 to display the two-dimensional trajectory and the three-dimensional trajectory using lines, and allows the user to visually recognize the background (map) of the two-dimensional trajectory and the three-dimensional trajectory. In addition, the control unit 201 causes the display unit 202 to display the height display based on the latitude / longitude information and the altitude information and the display of the two-dimensional map based on the map information at different scales. Further, the control unit 201 changes the angle of the map image displayed on the display unit 202 according to the posture detected by the posture detection unit 207.

  The display unit 202 is a liquid crystal display, for example, and displays information. The storage unit 203 includes a ROM and a RAM, and stores various information used by each unit of the electronic device 200. For example, the storage unit 203 stores map information. The wireless communication unit 204 communicates with other devices by wireless communication.

  The position information acquisition unit 205 acquires latitude / longitude information including the latitude / longitude of the current position based on GPS information from the satellite. The input unit 206 receives an operation input. The posture detection unit 207 detects the posture (for example, tilt) of the electronic device 200 (self device) using, for example, a three-axis acceleration sensor.

  FIG. 5 is a schematic diagram illustrating an example of latitude / longitude information generated by the electronic device 200 according to the present embodiment. In response to the operation input accepted by the input unit 206, the electronic device 200 starts recording the latitude / longitude log. The latitude / longitude log is data that associates the time measured with the latitude acquired by the position information acquisition unit 205 and the longitude acquired by the position information acquisition unit 205. In addition, the electronic device 200 ends the high-level log recording in response to the operation input accepted by the input unit 206. And the electronic device 200 produces | generates the latitude longitude information which shows the log of the recorded latitude longitude. As illustrated, the latitude / longitude information is an array in which time, latitude, and longitude are associated with each other. In the example shown in the figure, the latitude corresponding to the time “12:00:01” is “30.51”, and the longitude is “140.51”. The latitude corresponding to the time “12:00:31” is “30.52”, and the longitude is “140.52”.

  Next, a method in which the electronic device 200 displays a map image indicating a two-dimensional locus and a three-dimensional locus on a map based on altitude information and latitude / longitude information will be described. The electronic device 200 generates a map image using an existing 3D (three-dimensional) graphic library that is software for enabling stereoscopic display. The 3D graphic library, for example, automatically calculates the XY coordinates and color information of the liquid crystal display when setting the coordinates of the map, the viewpoint on the viewing side, the illumination angle of the light, etc. An image having a sense of depth (three-dimensional effect) is generated and displayed by converting an object into information on a two-dimensional plane.

  The electronic device 200 generates data to be read into the 3D graphic library. First, the electronic device 200 generates three-dimensional position information based on altitude information and latitude / longitude information.

  FIG. 6 is a schematic diagram illustrating an example of three-dimensional position information generated by the electronic device 200 according to the present embodiment. The control unit 201 combines the altitude information received from the electronic timepiece 100 and the generated latitude / longitude information into an array for each time to generate three-dimensional position information. As shown in the figure, the three-dimensional information is an array in which time, latitude, longitude, and altitude are associated with each other. In the example shown in the figure, the latitude corresponding to the time “12:00:01” is “30.51”, the longitude is “140.51”, and the altitude is “80 m”. The latitude corresponding to the time “12:00:31” is “30.52”, the longitude is “140.52”, and the altitude is “77 m”.

  Subsequently, the electronic device 200 determines the scale of the two-dimensional map from the latitude / longitude information in the generated three-dimensional position information. For example, the electronic device 200 calculates the scale that matches the display scale by obtaining the distance between the highest and lowest (north-south) and the distance between the leftmost and rightmost (west-east) in the latitude and longitude information.

  Thereafter, the electronic device 200 determines the scale in the height direction at the time of three-dimensional drawing from the height information in the generated three-dimensional position information. For example, the electronic device 200 obtains a difference between the maximum altitude and the minimum altitude in the altitude information and calculates a scale that matches the display scale. Hereinafter, the XYZ coordinate system is defined with the east direction of the two-dimensional map as the X-axis direction, the north direction as the Y-axis direction, and the height direction as the Z-axis direction.

  Next, the electronic device 200 generates a coordinate array for drawing a point for each time of the three-dimensional locus in the 3D graphics library. FIG. 7 is a schematic diagram illustrating an example of a coordinate array generated by the electronic device 200 according to the present embodiment. The coordinate array is an array of XYZ coordinate values of a three-dimensional locus. The X coordinate value indicates longitude, the Y coordinate value indicates latitude, and the Z coordinate value indicates height. For example, the first coordinate is [300, 400, 100], and the second coordinate is [301, 401, 95].

  Next, the electronic device 200 generates a map color coordinate array. The color coordinate array is obtained by adding colors to XYZ coordinate values. That is, the color coordinate array indicates the color of the XYZ coordinate value. For example, the electronic device 200 generates a color coordinate array of Z coordinate value (height) = 0 from map image data prepared at the determined scale of the two-dimensional map. FIG. 8 is a schematic diagram illustrating an example of a color coordinate array of a map generated by the electronic device 200 according to the present embodiment. In the illustrated example, the color of the XYZ coordinate values [0, 0, 0] is “RGB1”. The color of the XYZ coordinate value [0, 1, 0] is “RGB2”.

  Subsequently, the electronic device 200 generates a two-dimensional trajectory color coordinate array. The two-dimensional trajectory is obtained by setting the height of the three-dimensional trajectory to zero. For this reason, for example, the electronic device 200 generates a color coordinate array of a coordinate array in which the Z coordinate value (height) of the coordinate array of the three-dimensional locus is all zero. FIG. 9 is a schematic diagram illustrating an example of a color coordinate array of a two-dimensional locus generated by the electronic device 200 according to the present embodiment. In the example shown in the drawing, the color of the XYZ coordinate value [300, 400, 0] is “BLUE (blue)”, and the color of the XYZ coordinate value [301, 401, 0] is “BLUE”. That is, the color of the two-dimensional locus is set to blue.

  Subsequently, the electronic device 200 generates a color coordinate array of a three-dimensional trajectory. For example, the electronic device 200 generates a color coordinate array of the generated coordinate array. FIG. 10 is a schematic diagram illustrating an example of a color coordinate array of a three-dimensional locus generated by the electronic device 200 according to the present embodiment. In the example shown in the drawing, the color of the XYZ coordinate values [300, 400, 100] is “RED (red)”, and the color of the XYZ coordinate values [301, 401, 95] is “RED”. That is, the color of the three-dimensional locus is set to red.

  Then, the electronic device 200 reads the generated color coordinate array into the 3D graphic library. Subsequently, the electronic device 200 sets display parameters of the 3D graphic library. The display parameters include the coordinates of the view (viewpoint), whether or not to connect the two-dimensional trajectory and the three-dimensional trajectory with lines. Then, the electronic device 200 displays the map image generated by the 3D graphic library.

  11 to 14 are image diagrams showing examples of map images displayed by the electronic device 200 according to the present embodiment. As shown in the drawing, the map image displays a map M, a two-dimensional trajectory T2 on the map based on the latitude / longitude information, and a three-dimensional trajectory T3 having a height based on the latitude / longitude information and the altitude information. The two-dimensional trajectory T2 is displayed in blue, and the three-dimensional trajectory T3 is displayed in red.

  FIG. 11 shows a map image when the inclination of the map is 0 degree. As shown in the drawing, when the inclination of the map M is 0 degree, the three-dimensional trajectory T3 is not displayed on the map image. FIG. 12 shows a map image when the inclination of the map M is 30 degrees toward you. FIG. 13 shows a map image when the inclination of the map M is 50 degrees toward you. FIG. 14 shows a map image when the inclination of the map M is 70 degrees toward you. As shown in the figure, when the map M is tilted, a three-dimensional trajectory T3 corresponding to the tilt is three-dimensionally displayed on the map image. The control unit 201 changes the angle of the map image displayed on the display unit 202 (the inclination of the map M) according to the posture detected by the posture detection unit 207. For example, the control unit 201 substantially matches the inclination of the own device detected by the posture detection unit 207 with the inclination of the map M. Alternatively, the inclination of the map M can be changed according to an operation input received by the input unit 206.

  As described above, the electronic device 200 displays the three-dimensional locus including the height three-dimensionally with lines, so that the visibility is improved and the user can easily move the locus including the altitude change on the map. I can grasp it. Moreover, since the electronic device 200 displays the two-dimensional trajectory on the two-dimensional map, the user can easily grasp where the user has moved on the map.

  As described above, in the present embodiment, the display system 1 includes the electronic timepiece 100 and the electronic device 200. The electronic timepiece 100 includes an altitude measuring unit 108 that measures altitude by atmospheric pressure. The electronic device 200 includes a display unit 202, a storage unit 203 that stores map information, and a control unit 201. The control unit 201 acquires altitude information from the electronic timepiece 100 and causes the display unit 202 to display a map image that is three-dimensionally represented by the map information and the acquired altitude information.

  As a result, a highly accurate three-dimensional movement trajectory can be displayed even in the electronic device 200 without the atmospheric pressure sensor. Therefore, the user can easily grasp the background of the altitude change on the map. In addition, since the altitude measured by the atmospheric pressure is used, three-dimensional map information including the altitude is unnecessary. That is, since the altitude change can be expressed only by the two-dimensional map, the data capacity of the map information can be reduced, and the application development cost can be suppressed. In addition, when a trajectory is mapped on a three-dimensional map, the trajectory may be hidden by a high mountain in the foreground, and it is difficult to express the vertical movement of a building or subway. Since the display system 1 uses a two-dimensional map, the three-dimensional trajectory can be prevented from being hidden by the map. In addition to outdoor activities such as mountain climbing, it is possible to display a trajectory of a real movement of a building or subway. Therefore, visibility can be improved and the convenience of the user who grasps the process of the altitude change on the map can be improved.

The electronic device 200 further includes a position information acquisition unit that acquires latitude / longitude information, and the control unit 201 is based on a two-dimensional trajectory expressed in a plane based on the latitude / longitude information, and the latitude / longitude information and altitude information. A map image including a three-dimensional trajectory expressed in three dimensions is displayed on the display unit 202.
Thereby, since a two-dimensional trajectory which is a planar movement trajectory is shown on the map, it is possible to more easily grasp where the user has moved on the map.

  In addition, the control unit 201 causes the display unit 202 to display a three-dimensional trajectory using lines, and allows the user to visually recognize a map that is the background of the three-dimensional trajectory. This prevents the movement trajectory from hiding the map and improves visibility. In addition, absolute altitude is not necessary, and it can be expressed only by the difference between the maximum altitude and the minimum altitude.

  The control unit 201 can also cause the display unit 202 to display the display (height) based on the altitude information and the display (map) based on the map information on different scales. Thereby, the height can be emphasized and displayed, and the visibility is improved.

  The electronic device 200 further includes a posture detection unit 207 that detects the posture of the device itself, and the control unit 201 determines the angle of the map image displayed on the display unit 202 according to the posture detected by the posture detection unit 207. To change. That is, the inclination of the map image can be changed. Thereby, the user can see the map image with his / her own inclination.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. Since the configuration of the display system 1 in the present embodiment is the same as that in the first embodiment, the description thereof is omitted. The present embodiment is different from the first embodiment in that the electronic device 200 stores data at the time of operation in accordance with an operation input in the electronic timepiece 100 and displays based on the stored data.

  FIG. 17 is a diagram for explaining the operation of the display system 1 in the present embodiment. For example, the user performs a log point registration operation (for example, an operation of pressing a predetermined button on the key input unit 104) for registering log points on the electronic timepiece 100 at the points A, B, and C. The log points are points that store log point data, and in this example, are point A, point B, and point C. Log point data is data at log points, such as time, latitude, longitude, altitude, weather information, and photos. The weather information is, for example, weather, atmospheric pressure, temperature, humidity, wind direction, or wind speed.

  When the key input unit 104 receives an input of a log point registration operation, the CPU 101 of the electronic timepiece 100 writes the log point registration operation time, altitude, and pressure in the RAM 110 as log point registration data in association with each other. Then, the CPU 101 transmits log point registration data to the electronic device 200 via the wireless communication unit 109.

  The control unit 201 of the electronic device 200 receives log point registration data from the electronic timepiece 100 via the wireless communication unit 204. The control unit 201 acquires latitude and longitude corresponding to the time included in the log point registration data, weather information at the log point, and a photograph at the log point. Then, the control unit 201 includes the time included in the log point registration data, the altitude included in the log point registration data, the atmospheric pressure included in the log point registration data, the acquired latitude and longitude, the acquired weather information, The acquired photograph is associated and written into the storage unit 203 as log point data and stored. The control unit 201 registers log points by writing log point data to the storage unit 203.

  For example, the control unit 201 acquires the latitude and longitude corresponding to the time from the generated latitude / longitude information. Alternatively, the control unit 201 may acquire the current latitude and longitude from the position information acquisition unit 205. Further, the control unit 201 presents time, latitude, and longitude to a predetermined web service via the wireless communication unit 204, and acquires weather information at the log point. In addition, the control unit 201 causes a camera (not illustrated) to capture an image, and acquires the captured image data as a photograph at the log point. Alternatively, the control unit 201 may acquire a photograph by presenting latitude and longitude to a predetermined web service.

  In this way, the electronic device 200 stores log point data at each log point (A point, B point, and C point).

  Thereafter, the user performs a log point data display operation for instructing display of data relating to log points on the electronic device 200 at an arbitrary time (for example, at a point P). When the input unit 206 receives an input of a log point data display operation, the control unit 201 of the electronic device 200 reads the log point data of each log point stored in the storage unit 203. Based on the read log point data, the control unit 201 sets the data D1 to D6 between the latest log points (between points BC in this example) and the previous log point (in this example, points). (Between AB) and data D1 to D6 are generated, and the generated data D1 to D6 are displayed on the display unit 202.

  The data D1 is a distance between log points (for example, a distance between points AB, a distance between points BC, etc.). The control unit 201 calculates the distance between log points based on the latitude and longitude of each log point.

  The data D2 is a required time between log points (for example, an elapsed time taken for movement between points AB, an elapsed time taken for movement between points BC, etc.). The control unit 201 calculates the required time between log points based on the time of each log point.

  The data D3 is an average speed between log points (for example, an average speed between points AB, an average speed between points BC, etc.). The control unit 201 calculates an average speed between the log points based on the data D1 and the data D2.

  The data D4 includes elevation differences between log points (for example, an altitude difference between the points A and B, a difference between the maximum altitude and the minimum altitude between the points AB, an altitude difference between the points B and C, and between the points BC. The difference between the maximum altitude and the minimum altitude). The control unit 201 calculates the height difference between the log points based on the altitude of each log point.

  The data D5 is the point information “longitude, latitude, address” of the log point (for example, the latitude / longitude address of the point A, the latitude / longitude address of the point B, the latitude / longitude address of the point C, etc.). The control unit 201 acquires an address based on the latitude and longitude of each log point and the map information. Alternatively, the control unit 201 may acquire the address by presenting the latitude and longitude to a predetermined web service via the wireless communication unit 204.

  The data D6 is log point weather information (for example, weather, atmospheric pressure, temperature, humidity, wind direction, wind speed) and a log point photograph. Note that the atmospheric pressure may be acquired from a web service or measured by the electronic timepiece 100.

  In this embodiment, the control unit 201 displays the data between the latest log points and the data between the previous log points. However, the present invention is not limited to this. You may make it display all the data between each log point from the point which started) to the point immediately before the point P, or arbitrary parts.

In the present embodiment, when the electronic timepiece 100 receives an input of a log point registration operation, the electronic timepiece 100 transmits log point registration data to the electronic device 200. The log point registration data may be transmitted at other timings for communicating with the electronic device 200, such as the timing at which the electronic device 200 displays data D1 to D6.
Further, the data D1 to D6 can be simultaneously displayed on a single display screen, and at least two or more of the data D1 to D6 can be simultaneously displayed.

  In this embodiment, the electronic timepiece 100 accepts an input of a log point registration operation. However, the present invention is not limited to this, and the electronic device 200 may accept an input of a log point registration operation.

  Further, the electronic device 200 may share log point data and data D1 to D6 with other electronic devices.

  As described above, in the present embodiment, the electronic timepiece 100 includes a key input unit 104 for inputting registration of a point (log point), and a log indicating registration of a log point when the key input unit 104 receives registration of the log point. A CPU 101 for transmitting point registration data from the wireless communication means 109 to the electronic device 200. When the wireless communication unit 204 receives the log point registration data from the electronic timepiece 100, the electronic device 200 writes the log point data at the log point to the storage unit 203 to register the log point, and data D1 to D6 based on the log point data Is displayed on the display unit 202. Thereby, the data D1 to D6 related to the log points registered in the electronic timepiece 100 can be displayed on the electronic device 200.

[Third Embodiment]
Next, a third embodiment of the present invention will be described. Since the configuration of the display system 1 in the present embodiment is the same as that in the first embodiment, the description thereof is omitted.

  When measuring the altitude at the same point twice, for example, when starting from the start point (log recording start point) and returning to the same start point at the end point (log recording end point) ( That is, when the start point and the end point are the same point), the measured altitude value at the start point (the altitude value measured by the electronic timepiece 100) at the start point may differ from the measured altitude value at the end point. This is because, even at the same altitude at the same point, the atmospheric pressure value for measuring the altitude fluctuates due to changes in the weather between the start time and the end time. In such a case, when the three-dimensional trajectory T3 is displayed on the map image on the display unit 202 of the electronic device 200, different altitudes are displayed even at the same point, and the altitude display of the three-dimensional trajectory T3 at the start time and the end time is displayed. The lines will not be connected with a single stroke (does not match or does not intersect).

  Therefore, in the present embodiment, the electronic device 200 uses the measured altitude value at the start point and the measured altitude value at the end point when the start point and the end point are the same point (the same latitude and longitude). Thus, the point of correcting altitude information is different from the first embodiment.

  FIG. 18 is a graph illustrating altitude information before correction and altitude information after correction in the present embodiment. In this figure, the horizontal axis indicates time and the vertical axis indicates altitude value. The point at the start time t0 and the point at the end time t1 are the same point.

  FIG. 18A shows altitude information before correction. A solid line P shown in the figure is altitude information based on the measured atmospheric pressure sent from the electronic timepiece 100. The measured altitude value at the start time t0 is Pt0, and the measured altitude value at the end time t1 is Pt1. The solid line M is the amount of change in the measured altitude value based on the pressure value fluctuation due to the weather or the like between the start time t0 and the end time t1, and is represented by the following equation (1).

  FIG. 18B shows altitude information after correction. The control unit 201 of the electronic device 200 corrects the altitude information based on the change amount M between the measured altitude value Pt0 at the start point t0 and the measured altitude value Pt1 at the end point t1. Specifically, the control unit 201 corrects altitude information by subtracting M from P. That is, the control unit 201 calculates the corrected altitude value N1 (t) at the time point t by the following equation (2). Here, P (t) is a measured altitude value before correction at time t.

  Thereby, the altitude value of the start point which is the same point and the altitude value of the end point can be corrected to the same value.

  FIG. 19 is a flowchart illustrating a processing procedure of the first correction processing executed by the electronic device 200 according to the present embodiment. The electronic device 200 executes the processing shown in this figure before the above-described map image generation processing, for example, when receiving and storing altitude information from the electronic device 200.

  (Step S <b> 501) The control unit 201 receives altitude information P before correction based on the measured atmospheric pressure from the electronic timepiece 100 via the wireless communication unit 204. Thereafter, the process proceeds to step S502.

  (Step S <b> 502) The control unit 201 determines whether it is the end time of measurement (log recording). When the control unit 201 determines that it is the end point, the process proceeds to step S503. If the control unit 201 determines that it is not the end point, the process returns to step S501.

  (Step S503) The control unit 201 determines whether or not the start point and the end point are the same. For example, when the latitude and longitude at the start time and the latitude and longitude at the end time are substantially the same, the control unit 201 determines that the start point and the end point are the same. If the control unit 201 determines that they are the same, the process proceeds to step S505. If the control unit 201 determines that they are not the same, the process proceeds to step S504.

  (Step S504) The control unit 201 writes the altitude information P received from the electronic timepiece 100 into the storage unit 203 and stores it. Thereafter, the process ends.

(Step S505) The control unit 201 calculates an altitude difference and a time difference between the start time point and the end time point, and executes altitude correction according to the passage of time according to the above-described equation (2). Thereafter, the process proceeds to step S506.
(Step S506) The control unit 201 writes and stores the corrected altitude information N1 in the storage unit 203. Thereafter, the process ends.

  In the present embodiment, the control unit 201 corrects altitude information by comparing the end point and the start point. However, the present invention is not limited to this, and any two points (latitude and longitude are determined to be the same). The first correction process described above may be executed by comparing substantially the same point or a point having the same address.

  In the present embodiment, the electronic device 200 executes the first correction process at the end of the measurement (or at the same point measurement), but the timing for executing the first correction process is the same. Not limited to. For example, the position information and altitude information of all the measured points may be stored in the storage unit 203 of the electronic device 200, and the first correction process may be executed when the map image is displayed on the display unit 202. .

  As described above, in the present embodiment, the control unit 201 of the electronic device 200 obtains altitude information based on the amount of change in altitude value at a point (start point and end point) determined to be the same based on the latitude and longitude information. to correct. Accordingly, when the three-dimensional trajectory T3 is displayed on the map image on the display unit 202 of the electronic device 200 with the altitude information before correction, different altitudes are displayed even at the same point, and the altitude of the three-dimensional trajectory T3 at the same point. Although the display lines are not connected with a single stroke, by using the corrected altitude information, such a situation can be avoided, and reliability, convenience, and visibility are improved.

[Fourth Embodiment]
Next, a fourth embodiment of the present invention will be described. Since the configuration of the display system 1 in the present embodiment is the same as that in the first embodiment, the description thereof is omitted.

  While the user stays at one point, the atmospheric pressure value may fluctuate due to changes in the weather, etc., and the measured altitude value may fluctuate despite being continuously present at the same point. In such a case, when the map image is displayed on the display unit 202 of the electronic device 200, the altitude value of the point in the three-dimensional trajectory T3 changes with time even though the user is not moving. It will be.

  Therefore, in the present embodiment, when the electronic device 200 continues to exist within the predetermined distance d1 during the period from the time point t1 to the time point t2, the measured altitude value varies within the set range W or less. When this is the case, the fluctuation is regarded as fluctuation due to atmospheric pressure change (factors other than the user's movement) due to weather, etc., and the measurement altitude value at time t1 is corrected to the altitude value during the period from time t1 to time t2. Different from the first embodiment.

  The setting range W is a range that allows normal weather fluctuations. As an example of the allowable range, an altitude fluctuation range within ± 100 m / h corresponding to an atmospheric pressure fluctuation range per hour ± 10 hPa / h is taken as an example. Therefore, the setting range W is a value when 1h is converted into a communication sampling interval that is appropriately set. For example, when the communication sampling interval is 1 min, the set range W is about ± 1.7 m of 100 m × (1 min / 1 h). Note that the communication sampling interval is, for example, a time interval at which data can be transmitted / received to / from each other in a state where the electronic timepiece 100 and the electronic device 200 are communicatively connected by Bluetooth (registered trademark) communication. Information including data D1 to D6 is exchanged according to the timing of this communication sampling.

  FIG. 20 is a graph illustrating the altitude information before correction and the altitude information after correction in the present embodiment. In this figure, the horizontal axis indicates time, and the vertical axis indicates altitude. A solid line P is altitude information based on the measured atmospheric pressure sent from the electronic timepiece 100. Further, the period from the time point t1 to the time point t2 and the period from the time point t3 to the time point t4 continuously exist within the predetermined distance d1. d1 is a range that can be regarded as substantially the same point. Based on the latitude and longitude at each time point, the control unit 201 of the electronic device 200 determines whether or not the change amount is continuously within a predetermined distance d1 (is the same point). Further, W shown in the drawing indicates a set range of the vertical width around the measured altitude value P (t1) at the time point t1 or the measured altitude value P (t3) at the time point t3.

  As shown in FIG. 20A, the control unit 201 changes the altitude change during the period from time t1 to time t2 (measured altitude value P (t1) at time t1 and measured altitude value P (t2) at time t2. ) Is less than or equal to the set range W (ie, | P (t2) −P (t1) | <W), the change in altitude value is a change due to the weather or the like (a factor other than the user's movement). Therefore, the measured altitude value P (t1) at time t1 is corrected to be the altitude value during the period from time t1 to time t2. The solid line N2 shown in the figure is altitude information after correction. Further, when the correction is made, the control unit 201 calculates a correction value D = P (t1) −P (t2), writes it in the storage unit 203, and stores it.

  Thereby, the altitude value at the point where the user is continuously staying can be corrected to the same value.

  On the other hand, as shown in FIG. 20B, the control unit 201 changes the altitude between the time point t3 and the time point t4 (the measured height value P (t3) at the time point t3 and the measured height value P (t4) at the time point t4. )) Is larger than the set range W (that is, | P (t4) −P (t3) |> W), the change in the altitude value is not a change due to the weather or the like (for example, elevator, staircase). Further, the correction is made by adding the correction value D to the measured altitude value. Note that the control unit 201 does not correct the measured altitude value when the correction value D is not stored in the storage unit 203.

  FIG. 21 is a flowchart showing the processing procedure of the second correction processing executed by the electronic device 200 in the present embodiment. The electronic device 200 executes the processing shown in this figure before the above-described map image generation processing, for example, when altitude information is received from the electronic timepiece 100 and stored.

  (Step S <b> 601) The control unit 201 receives altitude information Ptk before correction based on the measured atmospheric pressure from the electronic timepiece 100 via the wireless communication unit 204. Ptk is altitude information at the kth reception sampling timing (sampling timing for receiving altitude information) tk. Thereafter, the process proceeds to step S602.

  (Step S602) The control unit 201 determines whether or not the latitude / longitude XYtk at the current reception sampling timing tk has changed little compared to the latitude / longitude XYtk-1 at the previous reception sampling timing tk-1. Specifically, the control unit 201 determines whether or not | XYtk−XYtk−1 | <d1. If the control unit 201 determines that there is no change (d1 or less), the process proceeds to step S603. On the other hand, if the control unit 201 determines that it has changed (d1 or more), it is considered to have moved at the reception sampling timing tk, and the process proceeds to step S606.

  (Step S603) The control unit 201 determines whether or not the difference between the measured altitude value Ptk at the current reception sampling timing tk and the measured altitude value Ptk-1 at the previous reception sampling timing tk-1 is within the set range W. judge. Specifically, the control unit 201 determines whether or not | Ptk−Ptk−1 | <W. If the control unit 201 determines that it is within the setting range W, the process proceeds to step S604. On the other hand, if the control unit 201 determines that it is larger than the set range W, the process proceeds to step S606.

(Step S604) The control unit 201 overwrites and stores the correction value D = Ptk−1−Ptk in the storage unit 203. Thereafter, the process proceeds to step S605.
(Step S605) The control unit 201 corrects the altitude value Ntk at the reception sampling timing tk to the measured altitude value Pkt-1 at the reception sampling timing tk-1, and writes Ntk = Pkt-1 in the storage unit 203 for storage. To do. Thereafter, the process returns to step S601.

(Step S606) The control unit 201 determines whether or not the correction value D is stored in the storage unit 203. If the control unit 201 determines that it is stored, the process proceeds to step S607. If the control unit 201 determines that it is not stored, the process proceeds to step S608.
(Step S607) The control unit 201 corrects the altitude value Ntk of the reception sampling timing tk to the measured altitude value Pkt + D using the correction value D, and writes Ntk = Pkt + D in the storage unit 203 for storage. Thereafter, the process returns to step S601.

  (Step S608) The control unit 201 considers that the measurement has not been stopped from the start of measurement, and does not correct the measured altitude value Ptk at the reception sampling timing tk as it is, and writes Ntk = Pkt in the storage unit 203 for storage. Thereafter, the process returns to step S601.

  In the present embodiment, the electronic device 200 executes the second correction process during measurement, but the timing for executing the second correction process is not limited to this. For example, the position information and altitude information of all the measured points may be stored in the storage unit 203 of the electronic device 200, and the second correction process may be executed when the map image is displayed on the display unit 202. .

  The electronic device 200 may execute the first correction process and the second correction process described above together. For example, the electronic device 200 may execute the second correction process during the measurement, and may execute the first correction process at an arbitrary timing (for example, after the end of the measurement). In this case, by combining the effects of both the correction processes, at least one characteristic among reliability, convenience, and visibility in altitude confirmation when the three-dimensional trajectory T3 is displayed on the map image is further enhanced. .

  As described above, in the present embodiment, the control unit 201 of the electronic device 200 determines that the altitude value changes within a predetermined range when the change amount of the latitude / longitude information is continuously within a predetermined distance. The altitude information is corrected based on the amount of change. Thereby, even if the atmospheric pressure changes due to the weather or the like while the user stays at the same point, the altitude value during that time can be corrected to the same value and displayed on the three-dimensional trajectory T3. , Reliability, convenience and visibility are improved.

  Note that all or some of the functions of each unit included in the electronic timepiece 100 or the electronic device 200 in the embodiment described above are recorded on a computer-readable recording medium, and this recording medium It may be realized by reading the program recorded in the above into a computer system and executing it.
