Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a functional configuration of an electronic timepiece 1 which is an embodiment of the electronic apparatus of the present invention.

  The electronic timepiece 1 is a digital electronic timepiece that displays a date and time using a liquid crystal display, although not limited thereto. The electronic timepiece 1 includes a CPU 10 (Central Processing Unit) (first area information acquisition means, second area information acquisition means, display control means), a ROM 11 (Read Only Memory) (area setting storage means), and a RAM 12 (Random Access). Memory) (corresponding setting storage means), the oscillation circuit 13, the frequency dividing circuit 14, the time measuring circuit 15 (time measuring means), the GPS reception processing section 16 (current position acquisition means) and its antenna 17, and the operation section 18 (Input means), a display driver 19, a display unit 20 (display means), a power supply unit 21, and the like.

  The CPU 10 performs various arithmetic processes and controls the overall operation of the electronic timepiece 1. The CPU 10 outputs a drive signal from the display driver 19 to the display unit 20 to display various information including date and time on the display unit 20. The CPU 10 operates the GPS reception processing unit 16 to acquire date / time information and current position information. Further, the CPU 10 corrects the date and time counted by the timing circuit 15 based on the obtained date and time information, or obtains the time zone according to the date and time counted by the timing circuit 15 and the current position, thereby obtaining the local time ( Area information).

  The ROM 11 stores various control programs 111 and setting data executed by the CPU 10. The program 111 includes, for example, a local time setting program for performing settings related to the local time based on information on the current position. The setting data includes local time setting data 112 (local time setting information) for calculating the local time according to the current position.

  The RAM 12 provides a working memory space to the CPU 10 and stores temporary data. The RAM 12 also includes data related to area setting, date and time correction results, positioning results, history of the set time zone and daylight saving time, a customization flag 121, and a customization data table 122 including customization data (setting information). It is remembered. The contents of the customization flag 121 and the customization data table 122 will be described later.

The oscillation circuit 13 generates and outputs a predetermined frequency signal. The oscillation circuit 13 includes a crystal oscillator, for example.
The frequency dividing circuit 14 divides the frequency signal output from the oscillation circuit 13 into a frequency signal used by the CPU 10 or the time measuring circuit 15 and outputs the frequency signal. The output frequency may be configured to be changeable by a control signal from the CPU 10.

  The timer circuit 15 counts the current date and time by counting and adding the frequency-divided signal input from the frequency divider circuit 14 to an initial value indicating a predetermined date and time. The date and time counted by the timer circuit 15 can be corrected by a control signal from the CPU 10.

  The GPS reception processing unit 16 receives radio waves in the L1 band (1.57542 GHz) using the antenna 17, demodulates and decodes transmission radio waves that are spectrum-spread from a positioning satellite, here, GPS satellites, and outputs signals (navigation). Message data). Further, the GPS reception processing unit 16 calculates the current date and current position based on the decoding result. The content of the decrypted signal is output to the CPU 10 in a predetermined format. Operation control related to reception, decoding, and output is performed by a control unit (microcomputer) provided in the GPS reception processing unit 16. A configuration for performing each operation related to demodulation, decoding, decoding, and control in the GPS reception processing unit 16 is formed as a module on a single chip and connected to the CPU 10. The operation of the GPS reception processing unit 16 is on / off controlled by the CPU 10 independently of the operations of the other units of the electronic timepiece 1. When the operation of the GPS reception processing unit 16 is turned off, power supply to the GPS reception processing unit 16 is interrupted to save power. Further, the GPS reception processing unit 16 is provided with a history storage unit, and date / time information, position information, and predicted trajectory data received and acquired so far are stored for a predetermined period and / or quantity.

  The operation unit 18 receives an input operation from the user. The operation unit 18 includes, for example, a push-button switch crown, and detects an operation such as a push-button switch being pressed, a crown being pulled out, and a rotation operation being performed. A corresponding electrical signal (operation signal) is output to the CPU 10.

  The display unit 20 has a display screen and displays various types of information including date and time information based on a drive signal from the display driver 19. The display screen is not particularly limited, but a segment type liquid crystal display (LCD) is used.

  The power supply unit 21 supplies power related to the operation of each unit at a predetermined voltage. The power supply unit 21 includes a battery, and includes, for example, a solar panel and a secondary battery as the battery. Alternatively, a replaceable button type dry battery may be used as the battery.

Next, setting of the time zone in the electronic timepiece 1 of the present embodiment will be described.
FIG. 2 is a diagram for explaining the setting data relating to the time zone setting.
3 and 4 are tables showing examples of the contents of each setting data.

  The local time setting data 112 in the ROM 11 includes a two-dimensional map 112a, an area setting value decoding table 112b, a time zone comparison table 112c, and a daylight saving time enforcement rule comparison table 112d. In the electronic timepiece 1 of the present embodiment, the local time setting data 112 is used to acquire the time zone to which the acquired current position belongs.

  The two-dimensional map 112a is world map data represented by a plurality of predetermined-sized areas L arranged in a two-dimensional matrix. A method for setting the area L will be described later. For each zone L, a zone setting value of 1 byte (8 bits) is set. This area set value is a set value related to area information of an area assigned to each area L and defined in association with each area L. Here, the area information is various information set for each area and used in the area, for example, the local time. The zone setting value of the present embodiment is a setting value associated with the time zone and daylight saving time enforcement rule for obtaining the local time of the region defined in association with the zone L. Therefore, in the electronic timepiece 1, the time zone and the daylight saving time enforcement rule of the area determined in association with the area are acquired by the area setting value. In each area L, an area setting value indicating a time zone and a daylight saving time enforcement rule of an area to which a point closest to a point whose latitude and longitude are both 0 degrees in the area L belongs is set.

  The zone setting value decoding table 112b holds table data for acquiring the time zone setting value and the daylight saving time enforcement rule setting value from the zone setting value.

FIG. 3 is a chart showing an example of the contents of the area set value decoding table 112b.
The area setting value indicated by 1 byte indicates a combination of the time zone setting value indicating the time zone of the area defined in association with the area L and the daylight saving time rule setting value indicating the daylight saving time enforcement rule. Each of these time zone setting values and daylight saving time enforcement rule setting values is indicated by a 1-byte value (in this case, hexadecimal display). As a result, information of 2 bytes is obtained.

FIG. 4 is a chart showing an example of the contents of the time zone comparison table 112c and the daylight saving time enforcement rule comparison table 112d.
In the time zone comparison table 112c, as shown in FIG. 4A, a time difference (TZ) from Coordinated Universal Time (UTC) is set for each time zone set value. Here, all the time differences can be acquired at intervals of 15 minutes from +12 hours to -11 hours 45 minutes, but time differences that are not currently used need not be set as time zone setting values, and are omitted as appropriate. You may do it.

In the daylight saving time execution rule comparison table 112d, as shown in FIG. 4B, daylight saving time execution information such as start time, end time and shift time (ST) of daylight saving time is set for each daylight saving time execution rule setting value. Alternatively, a daylight saving time period setting value indicating a combination of daylight saving time start timing and end timing is further determined and set for each daylight saving time implementation rule setting value. It is good also as acquiring in conversion to an actual daylight saving time period.
The shift time (ST) indicates the shift amount from the standard time during the daylight saving time implementation period. As this shift time, “0” is stored when daylight saving time is not implemented, and values other than “0” are stored with a sign when implemented.

  As described above, in the electronic timepiece 1, first, the area L to which the current position belongs is identified using the two-dimensional map 112a, and the area setting value corresponding to the area L is acquired. Next, using the zone setting value decoding table 112b, the time zone setting value and the daylight saving time enforcement rule setting value of the region determined in association with the zone L are acquired from the acquired zone setting value. Further, referring to the time zone comparison table 112c and the daylight saving time enforcement rule comparison table 112d, the time difference and the daylight saving time enforcement rule are acquired from each set value.

Here, the setting method of the area L is demonstrated.
FIG. 5 is a diagram for explaining a method of setting the section L.

In the electronic timepiece 1 of the present embodiment, the two-dimensional map 112a is divided into a plurality of map data files. These map data files are generated for each predetermined area (hereinafter referred to as zone Z) set in a predetermined latitude / longitude unit, and the current position's latitude / longitude value is obtained, thereby obtaining the current position. Can be discriminated in which map data file. For example, by setting the size of each zone Z to a range of 10 degrees in the latitude direction and 15 degrees in the longitude direction, the two-dimensional map 112a is divided into 432 map data files.
Each of these map data files is compressed in size, and only the map data file corresponding to the current position is expanded and read out in the RAM 12 to reduce the storage capacity and memory capacity.

  The zone Z corresponding to each map data file is further divided into a plurality of sub-regions (hereinafter referred to as mesh M). Each mesh M includes a predetermined number of sections L for each zone Z. The mesh M is a rectangular area including the predetermined number of sections arranged in a matrix in the latitude direction and the longitude direction. The map data file is compressed in units of the mesh M, and the compressed mesh data is arranged in a predetermined order with respect to those in the same zone Z and stored in the ROM 11. The size of the mesh M is set so that the compression efficiency is high for each map data file. Alternatively, the sizes of the meshes M may all be the same on the two-dimensional map 112a.

The area L is set based on the width of latitude and longitude. Therefore, the zone Z is divided into an equal number of sections L regardless of the latitude. In this case, the longer the area L, the shorter the length in the longitude direction. That is, the resolution is lower in the lower latitude area L. Therefore, in order to maintain the necessary spatial resolution even at low latitudes, the length of the low-latitude zone L can be set to about 500 m. The setting of the size of these areas L may be determined by the projection of the two-dimensional map 112a, for example. In such an array, the number of arrays is, for example, 43200 in the latitude direction and 86400 in the longitude direction.
In the case of such a setting based on latitude and longitude, the polar region such as Antarctica may be determined by a separate table.
In addition, when zone Z is divided by latitude and longitude, the distance per longitude interval becomes shorter as the latitude is higher. Therefore, by setting zone L according to the distance, the number of zones L per zone Z differs depending on the latitude. May be performed. By such division, the length of each zone L in the longitude direction can be kept substantially uniform, and the number of zones L can be made useless according to the length. As the length in the longitude direction, for example, about 500 m is preferably set.

  Next, the zone setting value referred to in the local time calculation by the electronic timepiece 1 will be described.

In the electronic timepiece 1 of the present embodiment, the GPS reception processing unit acquires the current position based on the transmission radio wave from the positioning satellite, and determines the area L from the area setting value of the area L to which the acquired current position belongs. Get the time difference and daylight saving time enforcement rules for the given region. Then, the date and time counted by the clock circuit 15 is corrected according to the acquired time difference and daylight saving time implementation rule, and the local time of the area determined in association with the area L is calculated and displayed.
As described above, in each zone L in the two-dimensional map 112a, the zone setting value indicating the time zone and daylight saving time enforcement rule of the zone to which the point closest to the point where latitude and longitude are both 0 degrees belongs to the zone L. Is set. In other words, in the present embodiment, the area defined in association with the area L is an area to which the point closest to the point where the latitude and longitude are both 0 degrees belongs to the area L. For this reason, when the zone L (current zone) to which the current position belongs includes a time zone boundary or a boundary between regions having different daylight saving time enforcement rules, the time zone assigned to the zone L in the two-dimensional map 112a and The daylight saving time enforcement rule may be different from the time zone and / or daylight saving time enforcement rule of the region to which the acquired current location belongs. In such a case, the electronic timepiece 1 of the present embodiment can calculate and display the local time by changing the reference destination to the area setting value of the area L adjacent to the area L to which the current position belongs. ing. Hereinafter, the change of the area setting value to be referred to will be described by taking as an example a case where the area L to which the current position belongs includes three areas with different time zones.

  FIG. 6 is a diagram illustrating the area setting values in the area L including the boundary of the time zone and the area L adjacent to the area L. FIG. 6A is a diagram illustrating time zone boundaries in the area L5 corresponding to the current position P1 and the areas L1 to L4 and L6 to L9 adjacent to the area L5, and FIG. It is a figure which shows the area setting value in L1-L9. Here, the adjacent area L refers to an area L sharing sides or vertices in a rectangle (polygon) indicated by a certain area L when the meridian and the latitude line in the two-dimensional map 112a are indicated by straight lines. The position of the section L on the two-dimensional map 112a is represented by a set of numbers indicating the arrangement order of the section L in the latitude direction (X direction) and the meridian direction (Y direction) in the two-dimensional map 112a. The positions of the sections L1 to L9 on the two-dimensional map 112a are (X1-1, Y1 + 1), (X1, Y1 + 1), (X1 + 1, Y1 + 1), (X1-1, Y1), (X1, Y1), ( X1 + 1, Y1), (X1-1, Y1-1), (X1, Y1-1), and (X1 + 1, Y1-1). In addition, it is assumed that the point closest to the point where the latitude and longitude are both 0 degrees in each area L is the point at the lower left vertex in the figure of the rectangle indicated by each area L.

  As shown in FIG. 6A, the areas L1 to L9 include areas A1, A2, and A3 belonging to three different time zones. The time zones of the regions A1, A2, and A3 are time zones TZ1, TZ2, and TZ3, respectively. Also, the daylight saving time implementation rules for the regions A1 to A3 are the same. The area L5 includes a part of each of the areas A1 to A3. The current position P1 of the electronic timepiece 1 is included in the area A3 in the area L5, and the time zone of the current position P1 is the time zone TZ3.

  On the other hand, as shown in FIG. 6B, in each of the areas L1 to L9, an area set value indicating a time zone in the area to which the lower left apex point in FIG. 6A belongs is set. In the example of FIG. 6B, the area set value LD1, the area set value LD2 in the areas L4, L5, L7, and L8 are set in the areas L1 to L3 and L6, and the area set value LD3 is set in the area L9. Here, the zone setting values LD1, LD2, and LD3 are zone setting values at which the time zones indicated by the time zone comparison table 112c are the time zones TZ1, TZ2, and TZ3, respectively. Accordingly, the time zone indicated by the zone setting value LD2 of the zone L5 to which the current position P1 belongs is the time zone TZ2, which is different from the time zone (time zone TZ3) of the current location P1.

In this case, the electronic timepiece 1 first calculates and displays the local time based on the time zone TZ2 indicated by the area setting value LD2 assigned to the area L5 corresponding to the acquired current position P1. This local time is the local time of the area A2, and is not the correct local time for the user of the electronic timepiece 1 at the current position P1 belonging to the area A3. Therefore, when the user performs an input operation on the operation unit 18 that requires customization (local time correction) within a predetermined duration, the electronic timepiece 1 refers to the calculation in the local time according to the input operation. Area setting value is changed. That is, in the electronic timepiece 1, the local time is calculated and displayed again by referring to any one of the area set values of the area L5 and the area L adjacent to the area L5 (areas L1 to L4, L6 to L9). Specifically, in the electronic timepiece 1, the area having the largest number assigned to the adjacent area L among the area setting values LD1 and LD3 excluding the area setting value LD2 that has already been referred to since the current position was last acquired. Calculate and display the local time with reference to the set value. In FIG. 6B, the area setting value LD1 is assigned to four areas L (areas L1 to L3, L6), and the area setting value LD3 is assigned to one area L (area L9). The zone setting value LD1 is referred to, and the local time is calculated and displayed based on the time zone TZ1 indicated by the zone setting value LD1. However, this local time is the local time of the area A1, and is not the correct local time for the user of the electronic timepiece 1 at the current position P1 belonging to the area A3. For this reason, when the user performs an input operation on the operation unit 18 that requires customization within a predetermined duration, the electronic timepiece 1 has an area setting value to be referred to again in the calculation of the local time according to the input operation. Be changed. Here, the area setting value LD3 that has not been referred to among the area setting values of the adjacent area L is referred to, and the area A3 appropriate for the user at the current position P1 based on the time zone TZ3 indicated by the area setting value LD3 is referred to. The local time is calculated and displayed.
In this way, the electronic timepiece 1 changes the zone setting value used for calculation of the local time, and calculates the local time appropriate for the user. In the above, only the point of obtaining the time zone by referring to the zone setting value is described, but the daylight saving time enforcement rule is also obtained from the zone setting value, and the time zone and daylight saving time implementation are performed in the calculation of each local time. Both rules are used.

  When the area setting value referred in the local time calculation is changed by the above method, the area L5 to which the current position belongs and the area L9 (corresponding selection area) in which the area setting value is referred to in response to the customization request by the user Is stored in the customization data table 122 of the RAM 12.

FIG. 7 is a chart showing an example of the contents of the customization data table 122.
This customization data table 122 shows the position of the area L to which the current position belongs (current area) in the two-dimensional map 112a and the current area of the area L to which the area setting value is referenced as a result of the customization request by the user in the area L. Customization data in which the relative position data in the latitude direction (X direction) and the meridian direction (Y direction) with reference to is stored. For example, the position (X1, Y1) of the section L5 to which the current position belongs in the above example, and the values (+1, −1) indicating the relative position with respect to the section L5 of the section L9 to which the section setting value is referred. Corresponding customization data is retained.
When the area to which the current position belongs is identified as the area L5 at the next acquisition of the current position, the area setting value corresponding to the area L5 is referred to based on the customization data related to the area L5 in the customization data table 122. The previous area L9 is identified, and the local time is calculated and displayed with reference to the area setting value LD3 of the area L9.

  Here, when the local time calculated and displayed based on the customized data is no longer appropriate for the user of the electronic timepiece 1 (for example, the user of the electronic timepiece 1 is in the area A1 in the example of FIG. 6A). The electronic timepiece 1 changes the area setting value referred to in the calculation of the local time in accordance with an input operation to the operation unit 18 that requests customization from the user. In this example, among the area setting values of the area L5 and a plurality of areas L adjacent to the area L5, the area setting values LD1 and LD2 excluding the area setting value LD3 that has already been referred to since the current position was last acquired are Since it is assigned to the same number of zones L, the zone setting value LD1 of zone L1 is referred to according to the order of arrangement of zones L, and the local time is calculated and displayed. This local time is appropriate for the user at the current point P2. Again, when the area setting value to be referenced is changed, the customization data that associates the area L5 to which the current position belongs and the area L1 to which the area setting value is referenced in response to a customization request by the user is the customization data table 122 of the RAM 12. Stored (updated).

  When there is an input operation on the operation unit 18 indicating a customization request by the user, when all the area setting values of the adjacent area L have already been referred to, a predetermined manual correction process is executed, and the user operation unit The local time is corrected in accordance with the input operation to 18. When the manual correction process is performed, the customization data table 122 includes customized data in which the position of the area L on the two-dimensional map 112a is associated with the data indicating that the manual correction process has been performed. Retained. In the example of FIG. 7, customized data associated with data (+2, +2) indicating that manual correction processing has been performed is held for the area L related to the position (X6, Y6). Next, when the current position is acquired, the customization data table 122 is referred to, and customization data including data (+2, +2) indicating that manual correction processing has been performed for the area L to which the current position belongs is performed. If it is retained, the local time is not calculated based on the time zone corresponding to the zone setting value and the daylight saving time enforcement rule.

Next, the setting calculation operation in local time in the electronic timepiece 1 will be described.
FIG. 8 is a flowchart showing a control procedure by the CPU 10 of the local time setting process executed by the electronic timepiece 1 of the present embodiment.

  This local time setting process is executed in accordance with, for example, a positioning operation command input operation to the operation unit 18 by the user.

  When the local time setting process is started, the CPU 10 operates the GPS reception processing unit 16 to cause the control unit (microcomputer) of the GPS reception processing unit 16 to start receiving radio waves from positioning satellites such as GPS satellites. Current position information and date / time information (Coordinated Universal Time (UTC)) calculated by the reception processing unit 16 is acquired (step S101). The position information is acquired from the GPS reception processing unit 16 when the GPS reception processing unit 16 calculates the positioning information by the positioning operation of the GPS reception processing unit 16, and the positioning operation is not performed by the GPS reception processing unit 16. When the positioning operation fails and the position information is not acquired, the current position is set in the electronic timepiece 1 at this time, and the position information corresponding to the city stored in the RAM 12 is acquired.

  The CPU 10 identifies the zone L to which the current position belongs in accordance with the latitude and longitude of the current position indicated by the position information acquired in step S101 (step S102).

  The CPU 10 determines whether or not the customization data including the position on the two-dimensional map 112a of the area L to which the current position identified in step S102 belongs is stored in the customization data table 122 of the RAM 12 (step S103).

  When it is determined that the customization data related to the area L to which the current position belongs is not stored in the RAM 12 (“No” in step S103), the CPU 10 sets the area setting for the area L to which the current position belongs. A value is acquired (step S104). Specifically, the CPU 10 specifies a map data file (zone Z) including the current position according to the latitude and longitude of the current position indicated by the acquired position information, and then in the specified map data file The mesh M including the current position is specified. And CPU10 specifies the arrangement | sequence order of each area | region L in the said mesh M from the header of the coding data of the specified mesh M, and acquires the area setting value set to the area L to which the present position belongs.

  When it is determined that the customization data related to the area L to which the current position belongs is stored in the RAM 12 (“Yes” in step S103), the CPU 10 confirms that the customization data has been subjected to the manual correction process. It is determined whether or not the data is indicated (step S105). When it is determined that the customization data is data indicating that the manual correction process has been performed (“Yes” in step S105), the CPU 10 ends the local time setting process.

  If it is determined that the customization data related to the area L to which the current position belongs is not data indicating that manual correction processing has been performed (“No” in step S105), the CPU 10 is indicated by the customization data. In addition, the area setting value of the area L corresponding to the area L to which the current position belongs is acquired (step S106).

  When step S104 or step S106 is completed, the CPU 10 calls a local time display process to be described later, calculates the local time based on the area setting value acquired in step S104 or step S106, and displays the calculated local time. The information is displayed on the unit 20 (step S107). Further, the CPU 10 causes the RAM 12 to store the zone setting value referred to in step S107.

  The CPU 10 displays an operation signal when there is an input operation indicating a customization request from the user to the operation unit 18 for a predetermined duration (for example, 15 seconds) after displaying the calculated local time on the display unit 20. By outputting the operation unit 18 to the CPU 10, it is determined whether or not there is a customization request from the user (step S108). In addition, the display mode at the local time on the display unit 20 after a predetermined duration time has elapsed may remain the same as that before the duration time has elapsed, or may differ after the duration time has elapsed. The display mode may be changed.

  When the input operation is performed on the operation unit 18 and the operation signal is output from the operation unit 18 before the predetermined period of time elapses, it is determined that there is a customization request from the user (“Yes” in step S108). ), The CPU 10 sets the customization flag 121 to ON (step S109). Here, the customization flag 121 is binary data indicated by 1 bit stored in the RAM 12, and finally the GPS reception processing unit 16 is set when the flag is set to ON (for example, set to “1”). This indicates that an input operation related to a customization request at the local time by the user has been performed on the operation unit 18 between the acquisition of the position information by the current time and the current time.

  The CPU 10 is referred to in the local time display process in step S107 after the current position is acquired in step S101 to the area setting value set in the area L to which the current position belongs and the plurality of areas L adjacent to the area L. It is determined whether or not there is an area setting value that does not exist (step S110). Specifically, the CPU 10 stores the area setting value stored in the RAM 12 in step S107, the area set value referred to in step S107, the area L to which the current position belongs, and the areas L adjacent to the area L. The above determination is made by comparing the set value.

  When it is determined that there is an unreferenced area setting value in the local time display process in step S107 (“Yes” in step S110), the CPU 10 selects any one of the unreferenced area setting values. Obtain (step S111). Specifically, the CPU 10 acquires the zone setting value having the largest number assigned to the zone L to which the current position belongs and the plurality of zones L adjacent to the zone L among the zone setting values not referenced. When step S111 ends, the CPU 10 shifts the process to step S107, calculates the local time based on the area setting value acquired in step S111, and displays the local time.

  When it is determined that there is no area setting value that is not referred to in the local time display process in step S107 (“No” in step S110), the CPU 10 calls a predetermined manual correction process to perform the user operation unit 18. The local time is corrected according to the input operation (step S112). The CPU 10 stores the corrected local time in the RAM 12 and displays the local time on the display unit 20.

  When step S112 ends, the CPU 10 stores the customization data in the RAM 12 (step S113). Specifically, the CPU 10 displays the customization data in which the position of the area L to which the current position belongs in the two-dimensional map 112a and the data indicating that the manual correction process has been performed are associated with the customization data table 122 in the RAM 12. Remember me.

  In step S108, when it is determined that a predetermined duration has passed without any input operation to the operation unit 18 and there is no customization request from the user ("No" in step S108), the CPU 10 It is determined whether or not the customization flag is set to ON (step S114).

If it is determined that the customization flag is set to ON (“Yes” in step S114), the CPU 10 stores the customization data in the RAM 12 (step S115). Specifically, the CPU 10 determines the area L to which the current position belongs in the area L to which the current position belongs in the two-dimensional map 112a and the area L in which the area setting value is acquired in step S111 executed last. Customized data composed of a value indicating a relative position as a reference is stored in the customized data table 122 of the RAM 12.
The customization data may be stored (updated) in the RAM 12 every time the area setting value is acquired in step S111, in addition to the case where the customization data is stored in step S115.
If it is determined that the customization flag is set to OFF (“No” in step S114), the CPU 10 ends the local time setting process.

  When step S113 or step S115 ends, the CPU 10 sets the customization flag to OFF (step S116). When step S116 ends, the CPU 10 ends the local time setting process.

Next, the local time display process in the electronic timepiece 1 will be described.
FIG. 9 is a flowchart showing a control procedure by the CPU 10 of the local time display process executed by the electronic timepiece 1 of the present embodiment.

  When the local time display process is started, the CPU 10 acquires time difference and daylight saving time information based on the area setting value acquired in any of steps S104, S106, and S111 of the local time setting process (step S201). Specifically, first, the CPU 10 refers to the zone setting value decoding table 112b and acquires the time zone setting value and the daylight saving time enforcement rule setting value corresponding to the acquired zone setting value. Subsequently, the CPU 10 refers to the time zone comparison table 112c to obtain a time difference corresponding to the obtained time zone setting value, and refers to the daylight saving time enforcement rule comparison table 112d to obtain the obtained summer time enforcement rule setting value. To obtain the daylight saving time period and shift time corresponding to. The CPU 10 stores the acquired time difference, daylight saving time period, and shift time in the RAM 12.

  Subsequently, based on the daylight saving time period acquired in step S201, the CPU 10 determines whether daylight saving time has been implemented and whether it is in the daylight saving time implementation period (step S202). If it is determined that the daylight saving time is in effect ("Yes" in step S202), the CPU 10 sets the time difference (TZ), daylight saving time period and shift time (ST) acquired in step S201, and local time setting. The local time is calculated based on the coordinated universal time (UTC) acquired in step S101 of the process (step S203). That is, the local time (LT) in the area to which the current position belongs is calculated by LT = UTC + TZ + ST in consideration of the shift time due to the implementation of daylight saving time.

  If it is determined in step S202 that the daylight saving time is not in effect (“No” in step S202), the CPU 10 proceeds to step S101 of the time difference (TZ) acquired in the process of step S201 and the local time setting process. The local time is calculated based on the coordinated universal time (UTC) acquired in step S204. That is, since the daylight saving time is not implemented, the shift time is not considered, and the local time (LT) in the area to which the current position belongs is calculated by LT = UTC + TZ.

  When the local time is calculated in the process of step S203 or step S204, the CPU 10 corrects the date and time measured by the clock circuit 15 using the acquired local time, operates the display driver 19, and operates the calculated local time. The time is displayed on the display unit 20 (step S205). Here, in addition to the local time, a display indicating the time zone used for the calculation of the local time, a display indicating whether or not daylight saving time is implemented, and a start date and time and end date and time of daylight saving time are displayed. From these displays, the user can determine whether the time zone and daylight saving time implementation status appropriately reflect the current position. When the local time is displayed, the CPU 10 ends the local time setting operation.

  As described above, the electronic timepiece 1 of the present embodiment includes the GPS reception processing unit 16 that acquires the current position, and the area information of each area that is defined in association with each of the world areas L that are divided in advance. It includes a ROM 11 that stores such area setting values, an operation unit 18 that outputs an operation signal in response to an input operation from the outside, and a CPU 10. The CPU 10 refers to the area setting value of the area L (current area) to which the current position belongs, acquired by the GPS reception processing unit 16, and acquires area information of the area determined in association with the current area (first area) Information acquisition means), the area setting value is referred to by referring to any one of the area setting values of the current area and a plurality of areas adjacent to the current area based on a predetermined operation signal output from the operation unit 18 The area information of the area determined in association with the area is acquired (second area information acquisition means). As a result, even when the local time is acquired near the boundary of each region of the world, the appropriate local time of the region to which the current position belongs is displayed, which is convenient for the user who acquires the local time near the boundary of the region. Can be improved.

  The electronic timepiece 1 also includes a display unit 20. The CPU 10 causes the display unit 20 to display the area information acquired from the CPU 10 as the first area information acquisition unit and the second area information acquisition unit in a predetermined manner over a predetermined duration (display control unit). The predetermined operation signal is output in response to a predetermined input operation received by the operation unit 18 during the duration time. As a result, the local time is determined when a predetermined duration has elapsed. Therefore, the local time can be determined without causing the user to perform an additional operation.

  Further, the CPU 10 as the second area information setting means, among the area information of areas determined in association with the current area and a plurality of areas L adjacent to the current area, every time a predetermined operation signal is input. Thus, the area setting values related to the area information determined in association with more areas L are selected and referred to in order. Thereby, when acquiring local time according to input operation to the operation part 18, the probability of displaying appropriate local time in an early order can be made high.

  The CPU 10 serving as the second area information acquisition unit includes a RAM 12 that stores setting information in which the current area and a corresponding selection area selected from any of the areas L adjacent to the current area are associated. When the area setting value is referred to by the CPU 10 as the second area information acquisition means based on the operation signal, and the area information of the area determined in association with the area L to which the area setting value is referred is acquired. The area associated with the area setting value referred to is stored in the RAM 12 as a corresponding selection area, and the CPU 10 as the first area information acquisition unit stores the RAM 12 when the current position is acquired by the GPS reception processing unit 16. If the setting information related to the current area is stored in the RAM 12, the corresponding selection area associated with the current area is set by the setting information. To get the local information with reference to the frequency setting value. As a result, when an appropriate local time at a position corresponding to a specific area in the area L is acquired based on an input operation to the operation unit 18, the current position at the position corresponding to the specific area from the next time onward. The correct local time can be displayed when the is acquired.

  The time setting circuit 15 that counts the current date and time is provided, the area setting value includes local time setting data, and the CPU 10 as the first area information acquisition means and the second area information acquisition means is included in the area setting value. The local time zone is obtained by referring to the local time setting data, acquiring the time zone of the area determined in association with the zone L to which the zone setting value is referred, and the time zone acquired at the date and time counted by the timing circuit 15 The local time that applies the time difference from is acquired as regional information. Thereby, the local time of the area defined in association with the current position can be easily obtained.

  The local time setting data includes daylight saving time implementation information, and the CPU 10 as the first regional information acquisition unit and the second regional information acquisition unit calculates the time difference from the coordinated universal time in the time zone and the deviation related to the implementation of daylight saving time. Get the local time included as local information. Thereby, the user can easily acquire the local time in which the daylight saving time used in the area is appropriately reflected regardless of whether the daylight saving time is in the area.

  Further, various programs can be installed by installing a program for causing a computer to execute the process according to the present invention in an electronic device including a configuration for acquiring a current position and an input unit for performing an input operation from the outside. The acquisition of the regional information related to the usage can be made more convenient for the user.

The present invention is not limited to the above-described embodiment, and various modifications can be made.
For example, in the above-described embodiment, an example has been described in which the electronic timepiece 1 acquires and displays the local time as regional information, but the present invention is not limited to this. For example, the electronic timepiece 1 acquires administrative unit information indicating an administrative unit such as a country or a state as an area to which the current position belongs from the area setting value, and acquires a holiday set for each administrative unit as the regional information. A calendar reflecting the holidays may be displayed. In addition, when the present invention is applied to an electronic device having a display unit capable of displaying a large amount of information, for example, various information such as laws, currencies, official languages, and international telephone numbers established for each administrative unit. May be acquired as regional information and displayed on the display unit.
In these cases, the administrative unit setting value is included in the area setting value decoding table 112b, and the administrative unit comparison table is stored in the RAM 12. Then, the CPU 10 obtains administrative unit information indicating the administrative unit to which the area L belongs by referring to the administrative unit comparison table by the administrative unit setting value indicated by the area setting value, and stores it in the ROM 11 or the RAM 12 based on the administrative unit information. The displayed area information may be displayed on the display unit.

  Further, when the area L to which the acquired current position belongs is an area L corresponding to a specific city, or the user is allowed to select a city where the user is staying and the area L corresponding to the latitude and longitude of the city is When the area L is identified, the area setting value to be referred for calculation in the local time may not be changed (that is, the customization request from the user is not accepted). By doing so, it is possible to prevent a problem that the local time displayed by the electronic timepiece 1 located in a specific city is different from the local time of the city.

  In the above-described embodiment, an example has been described in which one local time is calculated and displayed with reference to a different area setting value when there is a customization request from the user. When there is a capacity, a plurality of local times are displayed on the display unit 20 with reference to a plurality of zone setting values, and an appropriate one local time is selected by an input operation to the operation unit 18. Also good.

In the above embodiment, the local time display process is performed in step S107 of the local time setting process, and then a predetermined period is set in step S108 to receive a customization request from the user. It is not intended to be limited to. For example, the local time setting process may be started when a predetermined input operation indicating a customization request is performed on the operation unit 18 after the local time setting process is completed.
In the local time setting process started in this way, when it is determined in step S103 that the customization data related to the area L to which the current position belongs is stored in the RAM 12, the steps S105 and S106 are omitted. S107 may be executed. According to this, the manual correction process in step S112 is performed on the area L to which the current area belongs, and the customization data indicating that the manual correction process has been performed in step S113 is stored in the RAM 12. Even if it exists, the acquisition and display of the local time based on the area setting value can be performed again.

  In the above embodiment, when there is a customization request from the user, the area information having the largest number of the areas L to which the current position belongs and the areas L allocated in the plurality of areas L adjacent to the area L. Although the example which refers to is demonstrated, it is not the meaning limited to this. For example, the area setting value may be selected according to the arrangement order of the areas L.

  In the above embodiment, an example has been described in which the GPS reception processing unit 16 obtains the current date and time, and the date and time counted by the timer circuit 15 is corrected based on the current date and time. There may be provided other means capable of obtaining the above. For example, the electronic timepiece 1 includes a standard radio wave receiving unit that demodulates and outputs a time signal output (TCO) of a standard radio wave from radio waves in a long wavelength band, and uses both radio wave reception from GPS satellites and reception of standard radio waves. The date information may be corrected. In this case, the local time setting data 112 includes a standard radio wave reception area comparison table for acquiring information (standard radio wave information) related to the type of standard radio waves including the area L to which the current position belongs in the reception area (reception range). The standard radio wave information may be acquired from the standard radio wave reception area setting value indicated by the zone setting value.

  In the above embodiment, the time zone and daylight saving time enforcement rule are acquired based on the current position acquired by the GPS reception processing unit 16, and the date and time counted by the timing circuit 15 based on the time zone and daylight saving time enforcement rule are obtained. Although the example which corrects was demonstrated, it is not the meaning limited to this. For example, the time zone and daylight saving time enforcement rules are acquired based on the current position acquired by the GPS reception processing unit 16, and the time zone and daylight saving time enforcement rules are applied to the current date and time acquired by the GPS reception processing unit 16. The time may be calculated and displayed. Even in such an aspect, when the local time is acquired near the boundary of each region in the world, the appropriate local time of the region to which the current position belongs can be displayed, and the user convenience can be improved.

  Moreover, although the said embodiment demonstrated the example which performs a local time setting process and a local time display process under control by CPU10 of the electronic timepiece 1 main body, it is not the meaning limited to this. For example, the local time setting process and the local time display process may be executed under the control of a control unit (CPU, RAM, etc.) included in the GPS reception processing unit 16. However, in this case, the input / output process of the operation signal from the operation unit 18 in step S108 of the local time setting process is performed via the CPU 10 of the main body of the electronic timepiece 1. In step S205 of the local time display process, the local time is displayed on the display unit 20 under the control of the CPU 10 of the main body of the electronic timepiece 1 based on the local time input from the control unit of the GPS reception processing unit 16.

  In the above embodiment, the current position is calculated by receiving radio waves from a positioning satellite. However, even if the current position information is acquired from another method, for example, a mobile phone or a smartphone using proximity wireless communication. good.

  Further, it may be possible to count and display only the standard time of the time zone to which the area including the current position belongs without displaying the daylight saving time according to the user operation setting.

  Various methods can be used as a data setting method in the local time setting data 112. For example, 1-byte data is defined for each of the time zone and daylight saving time enforcement rules, and these combinations are combined into 1 byte data. However, from the beginning, the time zone and daylight saving time enforcement rules corresponding to the area setting value of 1 byte are set. May be made. The data lengths (number of bytes / number of bits) may be different from each other, and other parameters may be stored together.

  In the above embodiment, the digital electronic timepiece using the display unit 20 has been described as an example. However, the electronic timepiece to which the present invention can be applied is not limited thereto, and an analog electronic timepiece using a pointer, An electronic timepiece using both digital display and analog display may be used.

  In the above embodiment, the electronic timepiece 1 as an electronic device has been described as an example. However, the present invention can also be applied to other electronic devices capable of counting the date and time and acquiring current position information. is there. For example, in an electronic device such as a digital camera or a digital video camera, the local time according to the present invention can be used for setting the shooting date and time.

In the above description, an example in which the ROM 11 is used as a computer-readable medium of the program 111 according to the present invention is disclosed, but the present invention is not limited to this. As other computer-readable media, portable recording media such as flash memory, SSD (Solid State Drive), other nonvolatile memory, and CD-ROM can be applied. A carrier wave is also applied to the present invention as a medium for providing program data according to the present invention via a communication line.
In addition, details such as the specific configuration, processing contents, and procedures shown in the description of the above embodiments can be changed as appropriate without departing from the spirit of the present invention.

Although several embodiments of the present invention have been described, the scope of the present invention is not limited to the above-described embodiments, and includes the scope of the invention described in the claims and equivalents thereof. .
