  Hereinafter, a data recording apparatus and an image recording apparatus according to a first embodiment of the present invention will be described with reference to the drawings, taking an electronic camera as an example. FIG. 1 is a block diagram showing a configuration of an electronic camera 2 according to the embodiment. The electronic camera 2 includes a CPU 4. The CPU 4 includes a display control unit 14 that performs display control of the LCD 6 that measures a self-position based on a signal received from a GPS satellite, a selection screen, and the like. The touch panel 15 that detects the position of contact with a finger or the like on the display unit 12, the image capturing unit 16 that has an image sensor for capturing an object, the image storage unit 17 that stores image data captured by the image capturing unit 16, and the position measured by the GPS 6. An information storage unit 18 that stores self-location information as log data, a program storage unit 22 that stores a program for performing control and the like for storing log data in the information storage unit 18, and a memory card 26 that records image data and log data Are installed in a memory card slot 27 in which the battery is mounted and a battery chamber (not shown) in which the battery 28 is stored. 8 connector 30 makes it possible to supply electric power to each unit from being connected to clock 32 to measure the time. Here, an SD card or the like is used as the memory card 26, for example.

  Next, processing of the electronic camera 2 according to the first embodiment will be described with reference to the flowchart shown in FIG. First, when a log mode for acquiring log data is set by operating the touch panel 15, the CPU 4 starts acquiring self-position information by measuring the self-position with the GPS 6 (step S <b> 1). Next, the CPU 4 determines whether or not log data is stored in the information storage unit 18 (step S2). When the log data is stored in the information storage unit 18 (step S2: Yes), the CPU 4 performs a display such as “Please save the log data to the SD card” on the LCD display unit 24 (step S2). S3) A selection screen such as “Save / Do not save” is displayed on the LCD display unit 24.

  Next, the CPU 4 determines whether or not an operation for recording log data in the memory card 26 has been performed (step S4). For example, when “save” is selected on the selection screen, the CPU 4 determines that an operation for recording log data in the memory card 26 has been performed (step S4: Yes). Next, the CPU 4 reads the log data from the information storage unit 18 and records it on the memory card 26 (step S5), and then proceeds to the process of step S7. On the other hand, if “do not save” is selected on the selection screen, the CPU 4 determines that the operation of recording the log data in the memory card 26 has not been performed (step S4: No), and proceeds to the process of step S7. .

  In step S2, when log data is not stored in the information storage unit 18 (step S2: No), the process proceeds to step S7. Then, the CPU 4 displays a message such as “Please select a log data recording time” on the LCD display unit 24, and then selects a selection candidate such as “6 hours, 12 hours, 24 hours, 72 hours”. A selection screen showing the recording time to be displayed is displayed, and the operator is instructed to select the recording time (step S7).

  Here, for example, if the operator goes out for about several hours, he selects 6 hours as the recording time (step S8a). If the user goes out for half a day, 12 hours is selected as the recording time (step S8b). Similarly, 24 hours is selected as the recording time if going out all day (step S8c), and 72 hours is selected as the recording time if going out for about 3 days and 2 nights (step S8d).

  When a desired recording time is selected by operating the touch panel 15, the CPU 4 stores the self-location information acquired by the GPS 6 together with the positioning date and time in the information storage unit 18 as log data (step S9). For example, when 6 hours is selected as the recording time, as shown in FIG. 3, the information storage unit 18 uses the self-position information as log data at intervals of 1 minute from the reference time when the recording time is selected as the reference time. (Step S10).

  When the battery 28 in the battery chamber is charged or when the self-position information cannot be acquired, the CPU 4 does not store log data. For example, as shown in FIG. 4, in a recording time of 72 hours, a period during which the battery 28 in the battery chamber is charged (hereinafter referred to as a charging period), and a GPS signal cannot be received and self-location information is acquired. Suppose there was a period that could not be done. In this case, the CPU 4 does not store the self-location information acquired during the charging period in the information storage unit 18 as log data. In addition, during the period when the self-position information cannot be acquired, there is no object to be stored as log data, so log data is not stored.

  Next, the CPU 4 refers to the clock 32 and determines whether or not the recording time has elapsed from the reference time (step S11). For example, as shown in FIG. 3, when the recording time is 6 hours, the CPU 4 determines whether 6 hours have passed since the reference time. Further, as shown in FIG. 4, even when there is a period during which no log data is stored, the CPU 4 determines whether 72 hours, which is the recording time, has elapsed since the reference time. When the recording time has not elapsed since the reference time (step S11: No), the processing returns to step S10 and the log data is continuously stored.

  On the other hand, when the recording time has elapsed from the reference time (step S11: Yes), the CPU 4 finishes storing the log data in the information storage unit 18, and stores the log data stored in the information storage unit 18 as one log. The file is recorded on the memory card 26 (step S12). For example, when 6 hours as the recording time has elapsed from the reference time (see FIG. 3), the CPU 4 records the log data for 6 hours on the memory card 26 as one log file. Further, as shown in FIG. 5, in the recording time of 12 hours, when the battery 28 in the battery chamber is charged 3 hours after the reference time and the storage of log data is interrupted for 4 hours, the CPU 4 The log data stored in the information storage unit 18 for 3 hours before and 5 hours after the interruption period is recorded in the memory card 26 as one log file for 8 hours.

  As shown in FIG. 6, when 6 hours as the recording time have elapsed from the reference time during the charging period, the CPU 4 stores the log data in the information storage unit 18 when 6 hours have elapsed from the reference time. The log data is recorded in the memory card 26 as one log file.

  According to the electronic camera 2 according to the first embodiment, it is possible to select a recording time with good separation according to the action schedule of the operator, and therefore it is possible to acquire log data without waste. Further, since the log data acquired in one recording time is recorded in the memory card 26 as one log file, there is no need to re-edit the log data later. In addition, since the self-position information acquired during the charging period in which the electronic camera 2 is unlikely to move is not stored as log data, a log file that does not include useless information can be recorded in the memory card 26.

  In the above-described embodiment, when shooting is performed during the log data recording time, the image data of the shot image may be associated with the log data. For example, it is assumed that a release instruction is given by operating the touch panel 15 during a recording time, and a subject is photographed. In this case, the CPU 4 temporarily stores the image data of the photographed image in the image storage unit 17. When the recording time elapses from the reference time and the storage of the log data in the information storage unit 18 is finished, the CPU 4 records the log data as one log file in the memory card 26 and sets the shooting date and time as tag information. The image data added to the header portion is recorded in the memory card 26 in a predetermined file format such as Exif. As a result, the image data and the log data can be associated with each other based on the date / time information, and the operator can easily recognize the shooting position of the image.

  Further, in the above-described embodiment, the storage of log data may be terminated by an operator's operation. For example, when the recording time is 6 hours and the operation for terminating the storage of log data is performed when 3 hours have elapsed from the reference time, the storage of the log data is terminated when the operation is performed. Then, the log data for 3 hours may be recorded in the memory card 26 as one log file. Thereby, it is possible to accurately acquire log data for a period desired by the operator.

  Further, in the above-described embodiment, when the memory card 26 is not inserted in the memory card slot 27, the CPU 4 may end the series of processes while storing the log data in the information storage unit 18. When the log mode is set again, the operator may be instructed to record log data on the memory card 26.

  In the above-described embodiment, a map may be displayed on the LCD display unit 12 and a locus may be displayed on the map based on log data recorded in the memory card 26. For example, it is assumed that a log file A of log data acquired near Lake Motosu in Fujikawaguchiko and a log file B of log data acquired near Lake Kawaguchi are recorded in the memory card 26. In this case, as shown in FIG. 7, a trajectory (trajectory A) based on log data acquired near Lake Motosu and a trajectory (trajectory B) based on log data acquired near Lake Kawaguchi are displayed on the map. You may do it.

  Note that when log data is acquired using a normal logger, log data continues to be recorded until there is no more free space in the memory card. Therefore, for example, when positioning is performed near Lake Motosu and then the power is turned off and positioning is performed again near Lake Kawaguchi, the position information is stored as a single log data, which is shown in FIG. Thus, two trajectories (trajectory A and trajectory B) are displayed without separation. However, in the present invention, by selecting the recording time, the position information acquired at each location (near Lake Motosu and near Kawaguchiko) can be stored as separate log data. Two tracks (track A and track B) are displayed separately (see FIG. 7). Thereby, the locus based on the log data can be easily displayed on the map.

  In the above-described embodiment, the case where log data is not stored when the battery 28 in the battery chamber is charged is described as an example. However, the battery 28 is removed from the electronic camera 2. In this case, the log data may not be stored.

  Next, an electronic camera according to a second embodiment of the present invention will be described with reference to the drawings. Since the configuration of the electronic camera 2 according to the second embodiment is the same as that of the electronic camera 2 according to the first embodiment, the description thereof is omitted. Moreover, in the electronic camera which concerns on 2nd Embodiment, it demonstrates using the code | symbol of the structure of the electronic camera 2 which concerns on 1st Embodiment.

  In the second embodiment, the electronic camera 2 receives a log data recording start instruction and a log data recording end instruction using an operation member such as the touch panel 15 of the operator.

  FIG. 9 is a flowchart showing processing of the electronic camera 2 according to the second embodiment. The processes shown in steps S21 to S25 are the same as the processes shown in steps S1 to S5 of FIG. Next, the CPU 4 controls the display control unit 14 to display an icon for instructing to start recording log data on the LCD display unit 24 (step S26). When the icon for instructing the start of log data recording is operated via the touch panel 15, the CPU 4 starts storing the log data in the information storage unit 18 (step S27). Here, the log data includes the self-location information acquired by the GPS 6 and the positioning date and time when the self-location information is acquired. Further, the CPU 4 controls the display control unit 14 to display an icon for instructing the end of log data recording on the LCD display unit 24 (step S28). When the storage of log data in the information storage unit 18 is started, the CPU 4 stores the self-location information in the information storage unit 18 as log data at intervals of 1 minute, for example (step S29).

  Next, the CPU 4 determines whether or not an icon for instructing the end of log data recording has been operated via the touch panel 15 (step S30). When the icon for instructing the end of log data recording is not operated, the process returns to the process shown in step S29, and the CPU 4 continues to store the log data in the information storage unit 18.

  When the icon for instructing the end of log data recording is operated, the CPU 4 finishes storing the log data in the information storage unit 18 and records the log data in the memory card 26 as one log file (step). S31).

  According to the electronic camera of the second embodiment, log data recording is started by an operator's log data recording start instruction, and log data recording is ended by an operator's log data recording end instruction. The log data desired by the operator can be acquired. In addition, since log data acquired in one recording time is recorded in the memory card 26 as one log file, it is not necessary to re-edit the log data later.

  Next, an electronic camera according to a third embodiment of the present invention will be described with reference to the drawings. Since the configuration of the electronic camera 2 according to the third embodiment is the same as the configuration of the electronic camera 2 according to the first embodiment, the description thereof is omitted. Moreover, in the electronic camera which concerns on 3rd Embodiment, it demonstrates using the code | symbol of the structure of the electronic camera 2 which concerns on 1st Embodiment.

  In the electronic camera 2 according to the third embodiment, recording of log data is started and ended using an alarm function. Here, the alarm function uses the preset log data recording start time and log data recording end time to start recording the log data when the log data recording start time is reached, and to record the log data. This is a function for ending log data recording when the end time is reached. The log data recording start time and log data recording end time may be set by the operator via the touch panel 15, or may be set in advance by a preset or the like. As the log data recording start time and recording end time, for example, “every day from 8:00 to 10:00” or “every Sunday from 8:00 to 10:00” may be set.

  FIG. 10 is a flowchart showing processing of the electronic camera 2 according to the third embodiment. The processes shown in steps S41 to S45 are the same as the processes shown in steps S1 to S5 of FIG. Next, the CPU 4 determines whether or not the log data recording start time set with reference to the clock 32 has come (step S46). If the log data recording start time is not reached, the processing shown in step S46 is repeated.

  When the log data recording start time is reached, the CPU 4 starts storing the log data in the information storage unit 18 (step S47). Here, the log data includes the self-location information acquired by the GPS 6 and the positioning date and time when the self-location information is acquired. When the storage of the log data in the information storage unit 18 is started, the CPU 4 stores the self-position information in the information storage unit 18 as log data at intervals of 1 minute, for example (step S48).

  Next, the CPU 4 refers to the clock 32 and determines whether or not the log data recording end time has come (step S49). If the log data recording end time has not been reached, the process returns to step S48, and the CPU 4 continues to store the log data in the information storage unit 18.

  When the log data recording end time is reached, the CPU 4 finishes storing the log data in the information storage unit 18 and records the log data in the memory card 26 as one log file (step S50).

  According to the electronic camera according to the third embodiment, log data is recorded based on the set recording start time and recording end time, and therefore log data without waste can be acquired. Further, when the operator sets the log data recording start time and recording end time, it is possible to set a recording start time and a recording end time that are convenient for the operator. Further, since the log data acquired in one recording time is recorded on the memory card as one log file, there is no need to re-edit the log data later.

  Next, an electronic camera according to a fourth embodiment of the present invention will be described with reference to the drawings. Since the configuration of the electronic camera 2 according to the fourth embodiment is the same as that of the electronic camera 2 according to the first embodiment, the description thereof is omitted. Moreover, in the electronic camera which concerns on 4th Embodiment, it demonstrates using the code | symbol of the structure of the electronic camera 2 which concerns on 1st Embodiment.

  In the fourth embodiment, recording of log data is started when the self-position measured by the GPS 6 becomes the preset first location, and the self-position measured by the GPS 6 is preset. When the second place is reached, the log data recording is terminated. The first place and the second place may be set by the operator via the touch panel 15, or may be set in advance by a preset or the like.

FIG. 11 is a flowchart showing processing of the electronic camera according to the fourth embodiment.
The processes shown in steps S61 to S65 are the same as the processes shown in steps S1 to S5 of FIG. Next, the CPU 4 determines whether or not the self position has become the first place based on the self position measured by the GPS 6 (step S66). If the self position is not the first location, the process shown in step S66 is repeated.

  When the self position is the first location, the CPU 4 starts storing log data in the information storage unit 18 (step S67). Here, the log data includes the self-location information acquired by the GPS 6 and the positioning date and time when the self-location information is acquired. When the storage of log data in the information storage unit 18 is started, the CPU 4 stores the self-location information in the information storage unit 18 as log data at intervals of 1 minute, for example (step S68).

  Next, the CPU 4 determines whether or not the self position has become the second place based on the self position measured by the GPS 6 (step S69). If the self position is not the second location, the process returns to the process shown in step S68, and the CPU 4 continues to store the log data in the information storage unit 18.

  When the self location is the second location, the CPU 4 finishes storing the log data in the information storage unit 18 and records the log data as one log file on the memory card 26 (step S70).

  According to the electronic camera according to the fourth embodiment, it is possible to set a well-separated place as a place where log data recording starts and a place where log data recording ends according to the action schedule of the operator. Therefore, log data without waste can be acquired. Further, since the log data acquired in one recording time is recorded on the memory card as one log file, there is no need to re-edit the log data later.

  In the above-described fourth embodiment, the first location and the second location may be the same location. In this case, recording of log data is started at the first place, and after the self-position is separated from the first place by a predetermined distance or more, the second place which is the same place as the first place is used. Log data recording ends when the process returns. For example, when “Narita Airport” is set as the first place and the second place, recording of log data is started when the self-location is Narita Airport, and after going to another airport, etc. Log data recording ends when the location is Narita Airport.

  Next, an electronic camera according to a fifth embodiment of the invention will be described with reference to the drawings. Since the configuration of the electronic camera 2 according to the fifth embodiment is the same as the configuration of the electronic camera 2 according to the first embodiment, the description thereof is omitted. Moreover, in the electronic camera which concerns on 5th Embodiment, it demonstrates using the code | symbol of the structure of the electronic camera 2 which concerns on 1st Embodiment.

  In the fifth embodiment, the log data recording is started when the self-position measured by the GPS 6 is more than the first predetermined distance from the place where the self-position was recorded last, and the log data recording is started. The log data recording is terminated when the second predetermined distance or more away from the location.

  Here, the last location where the self-position was recorded may be the log data recording end position in the previously recorded log data, or may be the final positioning position which is the self-position last measured by the GPS 6. . When the final positioning position is used as the location where the self-position is last recorded, the CPU 4 stores the self-position measured last by the GPS 6 in the information storage unit 18. For example, the CPU 4 stores, in the information storage unit 18, the last position measured by the GPS 6 when the GPS signal cannot be received. In addition, the first predetermined distance and the second predetermined distance may be set by the operator via the touch panel 15 or may be set in advance by a preset or the like.

  FIG. 12 is a flowchart showing processing of the electronic camera according to the fifth embodiment. The processes shown in steps S81 to S85 are the same as the processes shown in steps S1 to S5 in FIG. Next, the CPU 4 reads the location where the self position was last recorded (step S86). That is, the CPU 4 reads the recording end position in the previously recorded log data from the log data recorded in the memory card 26. Alternatively, the final positioning position stored in the information storage unit 18 is read out.

  Then, based on the self-position measured by the GPS 6, it is determined whether or not it is away from the place where the self-position was last recorded by a first predetermined distance or more (step S87). If not more than the first predetermined distance, the process shown in step S87 is repeated.

  If the distance is greater than or equal to the first predetermined distance, the CPU 4 starts storing log data in the information storage unit 18 (step S88). Here, the log data includes the self-location information acquired by the GPS 6 and the positioning date and time when the self-location information is acquired. When the storage of log data in the information storage unit 18 is started, the CPU 4 stores the self-location information in the information storage unit 18 as log data at intervals of 1 minute, for example (step S89).

  Next, the CPU 4 determines based on the self-position measured by the GPS 6 whether or not the self-position is more than a second predetermined distance from the position where the log data recording was started in step S88 (step S90). If the distance is not more than the second predetermined distance, the process returns to step S89, and the CPU 4 continues to store the log data in the information storage unit 18.

  When the self position is more than the second predetermined distance from the position where the log data recording is started, the CPU 4 finishes storing the log data in the information storage unit 18 and stores the log data as one log file in the memory card. 26 (step S91).

  According to the electronic camera of the fifth embodiment, recording of log data is started when a predetermined distance or more is left from a location where the self-position was recorded last, and a predetermined distance or more is started from the position where recording of the log data is started. Since log data recording is terminated when the user leaves, log data without waste can be acquired. Further, since the log data acquired in one recording time is recorded on the memory card as one log file, there is no need to re-edit the log data later.

  In each of the above-described embodiments, the log data is stored in the information storage unit 18, and when the log data recording is completed, the log data is recorded in the memory card 26 as one log file. The log data may be directly recorded on the memory card 26 from the start of data recording. That is, the CPU 4 may start recording the log data on the memory card 26 when starting the recording of the log data, and record the log data on the memory card 26 as one log file when the recording of the log data is finished.

  Further, in each of the above-described embodiments, the operation is performed by the touch panel function, but may be performed by a button operation.

  Further, in each of the above-described embodiments, the electronic camera has been described as an example of the data recording device and the image recording device. However, if the operator has a function of selecting the recording time of log data, a normal data logger may be used. The present invention can also be applied to other electronic devices.

  In each of the above-described embodiments, when storage of log data in the information storage unit 18 is started, the CPU 4 stores the self-location information in the information storage unit 18 as log data at intervals of 1 minute, for example. It is not limited to the structure memorize | stored by a 1 minute space | interval, What is necessary is just the structure memorize | stored for every predetermined interval.

  In the second to fifth embodiments described above, as in the first embodiment, the self-position information acquired during the charging period where the electronic camera 2 is not likely to move is stored as log data. It is good also as a structure which does not. Further, the log data may not be stored in the period when the self-position information cannot be acquired, as in the first embodiment.
