I will let you. The operation unit 53 is operated by the user and adjusts the color tone of an image displayed on the display unit 51 and adjusts the volume of sound reproduced from the speaker 52.
[0038]
FIG. 5 shows an internal configuration example of the memory card 1 with the GPS reception function and the electronic device 41 shown in FIG.
[0039]
The GPS antenna 14 of the memory card 1 with a GPS reception function receives a GPS signal transmitted from a GPS satellite (not shown).
[0040]
The GPS signal processing unit 51 of the RF module 13 determines the GPS such as the latitude, longitude, altitude, time, speed, and heading direction of the current location where the electronic device 41 is used from the GPS signal received by the GPS antenna 14. Received data is calculated and recorded (stored) in the storage unit 61. The GPS signal processing unit 51 also adjusts the internal clock of the clock 52 to an accurate time based on the time data in the calculated GPS reception data. The GPS signal processing unit 51 further records the calculated GPS reception data (position data and time data) in the storage unit 61 as past trajectory data.
[0041]
This past trajectory data is data used when the GPS antenna 14 cannot receive a GPS signal due to an obstacle or the like.
[0042]
The clock 52 is driven by the power supply voltage supplied from the electronic device 41 via the interface (I / F) 62 and stores the internal clock adjusted by the GPS signal processing unit 51. The clock 52 is also driven by the power supply voltage supplied from the internal battery 53 when the GPS function memory card 1 is not attached to the electronic device 41 (that is, when there is no power supply). Maintain a calibrated internal clock.
[0043]
The storage unit 61 is composed of, for example, a nonvolatile memory, and is provided inside the memory card 11. The storage unit 61 stores communication data for the electronic device 41 and the memory card 1 with a GPS reception function to communicate with each other, such as driver software for driving the GPS reception function and interface protocol data. The storage unit 61 also records GPS reception data and past trajectory data supplied from the GPS signal processing unit 51.
[0044]
The GPS reception data, past trajectory data, and time data of the clock 52 stored in the storage unit 61 are sent to the electronic device 41 via the interface 62.
[0045]
A CPU (Central Processing Unit) 72 of the electronic device 41 acquires GPS reception data, past trajectory data, and time data from the memory card 1 with a GPS reception function via the interface (I / F) 71. The CPU 72 also adjusts the internal clock of the clock 74 to an accurate time based on the acquired time data. The CPU 72 further reads out and executes communication software necessary for communication such as driver software for driving the GPS reception function and interface protocol data from the memory card 1 with GPS reception function via the interface 71.
[0046]
The clock 74 stores an internal clock adjusted by the CPU 72.

The storage unit 73 stores use area data (information on the current area where the electronic device 41 is used), and the CPU 72 uses the GPS reception data acquired from the memory card 1 with a GPS reception function. The stored contents are updated. In addition, when GPS reception data cannot be acquired due to a shield or the like, the CPU 72 acquires past trajectory data stored in the storage unit 61 of the memory card 1 with GPS reception function, estimates the use area data, and stores it. The stored contents of the unit 73 are updated. The storage unit 73 also stores image data and audio data acquired from other devices.

[0049]
Next, a reception process executed by the memory card 1 with a GPS reception function will be described with reference to a flowchart of FIG. In starting this processing, it is assumed that the memory card 1 with a GPS reception function is in a state of being mounted on the electronic device 41.
[0050]
In step S1, the GPS antenna 14 determines whether or not a GPS signal is received from a GPS satellite (not shown), and waits until a GPS signal is received. If it is determined in step S1 that a GPS signal has been received, the process proceeds to step S2, where the GPS signal processing unit 51 uses the current electronic device 41 based on the GPS signal received by the GPS antenna 14. Calculate GPS reception data such as latitude, longitude, altitude, time, speed, and heading direction of the place.
[0051]
In step S3, the GPS signal processing unit 51 causes the storage unit 61 to record GPS reception data such as the latitude, longitude, altitude, time, speed, and heading direction calculated in the process of step S2. In step S4, the GPS signal processing unit 51 adjusts the internal clock of the clock 52 to an accurate time based on the time data of the GPS reception data calculated in the process of step S2.
[0052]
In step S5, the GPS signal processing unit 51 records the GPS reception data such as latitude, longitude, and time calculated in the process of step S2 in the storage unit 61 as past trajectory data in order to leave a GPS reception history. Let
[0053]
In step S6, the GPS signal processing unit 51 determines whether or not the memory card 1 with a GPS reception function has been removed from the electronic device 41, and determines that the memory card 1 with a GPS reception function has not been removed from the electronic device 41. If so, the process returns to step S1 and the above-described processing is repeated. That is, until the memory card 1 with a GPS reception function is removed from the electronic device 41, reception of GPS signals, calculation of GPS reception data, and recording of GPS reception data including past locus data are repeatedly performed.
[0054]
If it is determined in step S6 that the memory card 1 with GPS reception function has been removed from the electronic device 41, the process proceeds to step S7, where the clock 52 is driven by the power supply voltage supplied from the internal battery 53, and the accurate time is set. Continue to maintain. In step S <b> 8, the GPS signal processing unit 51 determines whether or not the memory card 1 with a GPS reception function is attached to the electronic device 41 again, and if the memory card 1 with a GPS reception function is not attached to the electronic device 41. When it determines, it returns to step S7 and repeats the process mentioned above. That is, the clock 52 maintains the time of the internal clock using the internal battery 53 until the memory card 1 with the GPS reception function is attached to the electronic device 41 and the power supply voltage is supplied from the electronic device 41. Continue.
[0055]
If it is determined in step S8 that the memory card 1 with a GPS reception function is again attached to the electronic device 41, the process returns to step S1 and the above-described processing is repeated. That is, GPS signal reception, GPS reception data calculation, and GPS reception data recording are performed again.
[0056]
Thus, the memory card 1 with a GPS reception function can always maintain an accurate time even when it is removed from the electronic device 41 and the power supply voltage is not supplied.
[0057]
Next, reception processing executed by the electronic device 41 will be described with reference to the flowchart of FIG. In starting this processing, it is assumed that the memory card 1 with a GPS reception function is in a state of being mounted on the electronic device 41.
[0058]
In step S11, the CPU 72 sends driver software for driving the GPS reception function stored in the storage unit 61 of the memory card 1 with the GPS reception function and communication software necessary for communication such as interface protocol data via the interface 71. read out. The CPU 72 drives the driver software for driving the GPS reception function so that the GPS antenna 14 receives the GPS signal and the GPS signal processing unit 51 can calculate the GPS reception data, and the GPS signal processing unit 51 calculates the GPS reception function driving driver software. In order that the received GPS data can be acquired via the interface 71, the memory card 1 with the GPS reception function and the electronic device 41 are brought into a mutual communication state using the interface protocol data.
[0059]
In step S12, the CPU 72 determines whether the GPS signal processing unit 51 of the memory card 1 with a GPS reception function has calculated new GPS reception data, and waits until it is determined that new GPS reception data has been calculated. If it is determined in step S12 that the GPS signal processing unit 51 has calculated new GPS reception data, the process proceeds to step S13, and the CPU 72 calculates the latitude, longitude, altitude, time, speed, The GPS reception data such as the heading direction and the accurate time data from the clock 52 are acquired via the interface 71 and recorded in the storage unit 73.
[0060]
In step S14, the CPU 72 adjusts the internal clock of the clock 74 to an accurate time based on the time data acquired in the process of step S13. In step S15, the CPU 72 updates the use area data stored in the storage unit 73 based on the latitude information and the longitude information in the GPS reception data acquired in the process of step S13.
[0061]
In step S <b> 16, the CPU 72 determines whether or not the memory card 1 with a GPS reception function has been removed from the electronic device 41. If it is determined that the memory card 1 with a GPS reception function has not been removed from the electronic device 41, Returning to S12, the subsequent processing described above is repeated. That is, until the memory card 1 with the GPS reception function is removed from the electronic device 41, the acquisition and recording of the GPS reception data and the update of the use area data are repeatedly performed.
[0062]
If it is determined in step S16 that the memory card 1 with a GPS reception function has been removed from the electronic device 41, the process is terminated.
[0063]
Thus, the electronic device 41 can specify the current position where the electronic device 41 is used based on the GPS reception data acquired from the memory card 1 with the GPS reception function, and the GPS reception function. Based on the time data acquired from the attached memory card 1, an accurate time can be maintained.

[0093]
Thus, the map data of the area where the PDA 80 is used is recorded in advance in the memory card 1 with the GPS reception function.
[0094]
Next, a map display process when the memory card 1 with the GPS reception function in which the map data is recorded as described above is attached to the PDA 80 will be described with reference to the flowchart of FIG.
[0095]
In step S21, the CPU 91 determines whether or not the memory card 1 with a GPS reception function is attached to the memory card interface 95, and waits until the memory card 1 with a GPS reception function is attached.
[0096]
If it is determined in step S21 that the memory card 1 with a GPS reception function is attached to the memory card interface 95, the process proceeds to step S22, and the CPU 91 determines whether or not map data is recorded in the memory card 1 with a GPS reception function. Determine.
[0097]
If it is determined in step S22 that map data is recorded, the CPU 91 reads the map data recorded in the memory card 1 with a GPS reception function and stores it in the Flash ROM 93.
[0098]
On the other hand, when it is determined in step S22 that map data is not recorded, the process proceeds to step S23, and map data is acquired (recorded) by the method described above.

The map image 131 shown in FIG. 11 displays roads, intersection names, facility names, bus stop names, and the like.
[0102]
In step S25, the CPU 91 determines whether or not GPS data has been received, that is, whether or not the GPS signal processing unit 51 of the memory card 1 with the GPS reception function has calculated new GPS reception data, and the GPS signal processing unit. It waits until it determines with 51 having calculated new GPS reception data.
[0103]
If it is determined in step S25 that the GPS signal processing unit 51 has calculated new GPS reception data, the process proceeds to step S26, and the CPU 91 receives GPS reception data such as latitude information and longitude information calculated by the GPS signal processing unit 51. Is stored in the Flash ROM 93. At this time, since the current position where the PDA 80 is used is specified based on the calculated latitude information and longitude information, the map image 131 displayed on the display unit 81 uses the PDA 80. The image 131 is updated so that the surrounding area of the current position is displayed.

In step S41, the main control unit 171 determines whether or not the memory card 1 with a GPS reception function is installed in the memory card slot 156, and waits until the memory card 1 with a GPS reception function is installed.
[0146]
If it is determined in step S41 that the memory card 1 with a GPS reception function is attached, the process proceeds to step S42, and the main control unit 171 determines whether POI data is recorded in the memory card 1 with a GPS reception function. To do.
[0147]
If it is determined in step S42 that the POI data is recorded, the main control unit 171 reads the POI data recorded in the memory card 1 with the GPS reception function, records it inside, and then proceeds to step S45. .
[0148]
On the other hand, when it is determined in step S42 that POI data is not recorded, the process proceeds to step S43, and the main control unit 171 further determines whether or not POI data is necessary. Specifically, the POI data is specified by designating whether or not the user wants to record the image data captured by the CCD camera 153 of the mobile phone 140 in association with the place name or facility name of the shooting location. Whether or not is necessary is determined.
[0149]
If it is determined in step S43 that POI data is necessary, the process proceeds to step S44, and the main control unit 171 acquires (records) POI data by the method described above.
[0150]
The POI data may be once recorded in the memory card 1 with GPS reception function, and then read out from the POI data and recorded in the main controller 171. Alternatively, the POI data may be downloaded from the Internet or a server. May be recorded directly in the main control unit 171.
[0151]
In step S <b> 45, the main control unit 171 determines whether the CCD camera 153 of the camera unit 152 has captured a desired imaging target by operating the operation key 161 or the jog dial 164 by the user, and the CCD camera 153. Waits until the desired object is imaged.
[0152]
If it is determined in step S45 that the CCD camera 153 has captured a desired subject, the process proceeds to step S46, and the main control unit 171 determines that the GPS signal processing unit 51 of the memory card 1 with the GPS reception function is new GPS reception data. It is determined whether or not it is calculated, and waits until it is determined that new GPS reception data is calculated.
[0153]
If it is determined in step S46 that the GPS signal processing unit 51 has calculated new GPS reception data, the process proceeds to step S47, where the main control unit 171 has the latitude information and longitude information calculated by the GPS signal processing unit 51.

[0155]
In step S49, the main control unit 171 determines whether or not the user has operated the operation key 161 or the jog dial 164 to input a command indicating the end of imaging. If it is determined that the imaging has not ended, the process returns to step S45. The above process is repeated. That is, until the imaging process is completed, imaging of a desired imaging target, acquisition of GPS reception data, and recording of image data to which GPS reception data is added are performed.
[0156]
If it is determined in step S43 that POI data is not necessary, the process proceeds to step S50, where the main control unit 171 operates the operation key 161 or the jog dial 164 to cause the CCD camera 153 of the camera unit 152 to operate. It is determined whether or not a desired imaging target has been imaged, and the process waits until the CCD camera 153 images the desired imaging target.
[0157]
If it is determined in step S50 that the CCD camera 153 has captured a desired subject, the process proceeds to step S51, where the main control unit 171 controls the storage / playback unit 183 to store the image data captured by the CCD camera 153. It records on the memory card 1 with a GPS reception function.
[0158]
In step S52, the main control unit 171 determines whether or not the operation key 161 or the jog dial 164 is operated by the user and a command indicating the end of imaging is input. If it is determined that the imaging is not ended, the process returns to step S50. The above process is repeated. That is, until the imaging process is completed, imaging of a desired imaging target and recording of image data are performed.
[0159]
If it is determined in step S49 or step S52 that the imaging has been completed, the process is terminated.

[0162]
In step S61, when the operation key 161 or the jog dial 164 is operated by the user's operation and a command indicating the display of the captured image is input, the main control unit 171 controls the storage / reproducing unit 183 to perform the GPS reception function. The image data recorded in the attached memory card 1 is read out.
[0163]
In step S62, the main control unit 171 determines whether or not latitude information and longitude information are added to the read image data, and the latitude information and longitude information are added to the read image data. If YES, the process proceeds to step S63, and the corresponding POI data is read from the inside based on the latitude information and longitude information added to the read image data.
[0164]
In step S64, the main control unit 171 adds POI data corresponding to the read image data, and outputs it to the LCD control unit 176 via the main bus 181. The LCD control unit 176 displays the POI data on the liquid crystal display 155 together with the supplied image data. Thereby, for example, as shown in FIG. 18A, an image 201 to which a place name 211 is added is displayed.
[0165]
In the image 201 shown in FIG. 18A, “Lake Tahoe” is displayed as the place name 211.
[0166]
In step S66, the main control unit 171 determines whether or not all image data has been read from the memory card 1 with the GPS reception function. If it is determined that all image data has not yet been read, the process returns to step S61. The above processing is repeated.
[0167]
That is, when the user inputs a command indicating the display of the next image data, if there is image data that has not yet been read in the memory card 1 with the GPS reception function, it is read and the liquid crystal display 155. Thereby, for example, as shown in FIG. 18B, the image 202 with the place name 212 added is displayed.
