Description

  The present invention relates to an imaging apparatus capable of handling position information, a control method thereof, and a program thereof.

  There is known an apparatus such as a GPS logger that periodically acquires position information and records a user's movement trajectory as log data. For example, Patent Document 1 describes a GPS logger that has a function of performing a logging process of periodically recording position information and generating log data representing a movement route. Log data generated by the GPS logger is recorded on a recording medium of the GPS logger.

  On the other hand, in recent years, an example in which a digital camera and GPS are linked is also known, and various application examples such as a digital camera having a function of adding position information to image data are conceivable.

Japanese Patent Laid-Open No. 2001-143040

  As one example of the digital camera as described above, it is conceivable that the function of the GPS logger described above is mounted on the digital camera. In such a digital camera, it is considered that position information acquired by a GPS function mounted on the device itself is recorded as log data on a recording medium connected to the digital camera.

  However, this recording medium also records image data acquired by photographing processing which is a main function of the digital camera. That is, there is a possibility that the process of recording the captured image data on the recording medium and the process of recording the position information on the recording medium as log data may be executed in parallel. For this reason, if the photographing process is performed while the recording medium is being accessed to record the position information, the process of recording the photographed image data on the recording medium may be delayed.

  The present invention has been made in view of the above points, and has an object to appropriately control access to a recording medium.

In order to solve the above problems, an imaging apparatus according to the present invention includes an image recording unit that performs an image recording process for recording an image obtained by imaging a subject as an image file on a recording medium, and a signal received from an external device. Acquisition means for acquiring position information based on the position information, and position recording means for performing position recording processing for recording the position information acquired by the acquisition means on the recording medium as a log file that is a file different from the image file. by pre-Symbol image recording means when the image recording process is executed, the acquisition unit acquires the position information in parallel to the image recording process, the position recording means to said recording medium position information as a log file It is characterized by not recording.

  It is possible to prevent the image data recording process by the imaging process from being hindered by the position information recording process by the logging process.

  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated in detail using attached drawing.

  The embodiment described below is an example as means for realizing the present invention, and may be appropriately modified or changed depending on the configuration of the apparatus to which the present invention is applied and various conditions. Each embodiment can also be combined as appropriate.

[First Embodiment]
First, a digital camera equipped with GPS, which is an example of an imaging apparatus equipped with a positioning device, according to the present embodiment will be described. The configuration of the digital camera is shown in FIG.

  In the digital camera 100, a central processing unit (CPU) 101 controls each part of the digital camera 100 according to an input signal and a program described later. For example, it takes control of shooting processing, playback processing, logging processing, and the like. Each process will be described later. Note that the control performed by the CPU 101 may be performed by a single piece of hardware, or the entire apparatus may be controlled by a plurality of pieces of hardware sharing the processing.

  The imaging unit 102 performs a shooting operation. The photographing operation is processing for converting subject light imaged by a lens included in the imaging unit 102 into an electrical signal, performing noise reduction processing, and the like, and outputting digital data as image data. The output image data is recorded on the recording medium 107.

  The nonvolatile memory 103 stores a program (firmware) for controlling each part of the digital camera 100 and various setting information. A program for the CPU 101 to control processing shown in each flowchart described later is also recorded in the nonvolatile memory 103.

  The work memory 104 is a memory for developing and executing a program stored in the nonvolatile memory 103. The work memory 104 is used as a work area for the CPU 101.

  The display unit 105 performs display of viewfinder image data at the time of photographing, display of photographed image data, character display for interactive operation, and the like. Note that the display unit 105 is not necessarily provided in the digital camera 100, and the digital camera 100 may be connected to the display unit 105 as long as it has at least a display control function for controlling the display of the display unit 105.

  The operation unit 106 is used by the user to instruct the operation of the digital camera. The operation unit 106 is configured to include, for example, operation members such as a power button for instructing power on / off of the digital camera, a release switch for performing photographing processing, and a playback button for viewing image data. Is done.

  The recording medium 107 can record image data output from the imaging unit 102, position information and date / time information acquired by the GPS 108 described later. The recording medium 107 may be configured to be detachable from the digital camera 100 or may be built in the digital camera 100. That is, the digital camera 100 only needs to have at least means for accessing the recording medium 107.

  The GPS 108 performs a positioning process. The positioning process is a process of receiving a signal from a GPS satellite and acquiring position information of the GPS 108 from the received signal. In the present embodiment, date / time information is also acquired. In the present embodiment, GPS is used. However, the present invention is not necessarily limited to GPS, and may be an apparatus that acquires position information from an external device such as a mobile phone base station or an acceleration sensor. The GPS 108 may be detachable from the digital camera 100 or may be built in. That is, the digital camera 100 only needs to have a function of acquiring at least position information. Using this GPS 108, the CPU 101 performs a logging process. In the logging process, the CPU 101 controls the GPS 108 to perform a positioning process periodically. Then, the CPU 101 generates log data by associating the acquired position information and date / time information, and stores the log data in the recording medium 107 as a log file. In the saved log file, the position information and date / time information acquired periodically are added until the date when the log file is created ends. At that time, the CPU 101 controls to access the recording medium 107 every time the position information and the date / time information are acquired, and to add the position information and the date / time information to the log file recorded in the recording medium 107. While the CPU 101 detects the date change, a new log file is generated, and the position information and date / time information acquired after the date change is added to the new log file. FIG. 11 shows an example of the log file. A movement trajectory of the digital camera 100 is obtained by connecting positions corresponding to a plurality of pieces of position information included in one log file in order of corresponding dates and times. The user can arbitrarily switch on / off the function of performing the logging process via the operation unit 106. Note that a flag is held in the non-volatile memory 103 as determination information for determining on / off. When the flag is on, 1 is recorded in the flag, and when it is off, 0 is recorded in the flag.

The timer 110 measures the interval for performing the positioning process in the above-described logging process. Note that the timer unit 110 includes a CPU different from the CPU 101 and is configured to be able to perform timing in a state where power supply to each unit of the digital camera 100 including the CPU 101 other than the timer unit 110 is stopped. The timer unit 110 also has a function of controlling power supply to each unit of the digital camera 100 including the CPU 101 and the GPS 108.
The above is the configuration of the digital camera in this embodiment.

  Next, an example of the appearance of a digital camera is shown in FIG. It comprises a digital camera main body 100, a display 201 for displaying a GUI or captured image data, a power button 202, a release switch 203, a playback button 204 for starting a playback mode, and an LED 205.

  Among these, the numbers of the digital camera main body are the same as those in FIG. The display 201 corresponds to the display unit 105 in FIG. Further, the power button 202, the release switch 203, and the playback button 204 are included in the operation unit 106 in FIG.

  Next, the operation of the digital camera 100 of this embodiment will be described.

  FIG. 3 is a flowchart showing the operation of the digital camera 100. The processing shown in each step of this flowchart is realized by the CPU 101 loading a program stored in the non-volatile memory 103, developing it in the work memory 104, and controlling each part of the digital camera 100 according to the program. . The same applies to each process shown in the following flowcharts.

  First, in step S <b> 301, the CPU 101 determines whether this process is started by pressing the power button 202 or whether this process is started by pressing the playback button 204.

  If the CPU 101 determines in step S301 that the process has started due to the power button 202 being pressed, the process proceeds to step S302.

  In step S302, the digital camera 100 enters a shooting mode and performs a shooting process. In the shooting mode, the digital camera 100 supplies power to devices required for shooting processing such as the imaging unit 102. The photographing process will be described with reference to the flowchart shown in FIG.

  If the CPU 101 determines in step S301 that the process has started due to the power button 202 being pressed, the process proceeds to step S303.

In the playback mode, the digital camera 100 supplies power to devices necessary for playback processing, such as the display unit 105. The reproduction process will be described with reference to the flowchart shown in FIG.

  When the photographing process or the reproduction process ends, the process proceeds to step S304. In step S <b> 304, the CPU 101 performs an end preparation process for turning off the power of the digital camera 100. The end preparation process will be described later. When the process of step S304 ends, this process ends, and the digital camera 100 is turned off.

  Next, the photographing process will be described with reference to FIG. FIG. 4 is a flowchart showing the operation of the digital camera 100 in the photographing process. This photographing process is an example of an image recording process.

  First, in step S401, the CPU 101 determines whether or not the power button 202 has been pressed, or whether or not the operation unit 106 has not accepted an operation for a certain period of time. In step S401, if the CPU 101 determines that the power button 202 has been pressed or the operation unit 106 has not accepted an operation for a certain period of time, this process ends, and the process returns to the process of FIG. Otherwise, the process proceeds to step S402.

  In step S402, the CPU 101 determines whether or not the playback button 204 has been pressed. If the CPU 101 determines in step S402 that the playback button 204 has been pressed, the process proceeds to a playback process described later. On the other hand, if the CPU 101 determines in step S402 that the playback button 204 has not been pressed, the process proceeds to step S403.

  In step S403, the CPU 101 determines whether the release switch 203 has been pressed.

  Next, in step S405, the CPU 101 controls the display unit 105 to display the review display of the image data acquired in step S404.

  Next, in step S406, the CPU 101 determines whether or not the free capacity of the recording medium 107 is an amount that can store the image data acquired in step S404. If the CPU 101 determines in step S406 that the image data acquired in step S404 can be stored in the recording medium 107, the process proceeds to step S407.

  In step S407, the CPU 101 displays on the display unit 105 that the image data acquired in step S404 cannot be stored in the recording medium 107 (for example, displays a message such as “Not enough free space”). Thereafter, the process returns to step S401.

  On the other hand, if the CPU 101 determines in step S406 that the image data acquired in step S404 can be stored in the recording medium 107, the process proceeds to step S408.

  In step S408, the CPU 101 records the image data acquired in step S404 on the recording medium 107 as an image file. Thereafter, the process returns to step S401.

  The above is the description of the operation of the digital camera 100 in the shooting process.

  First, in step S <b> 501, the CPU 101 determines whether image data is recorded on the recording medium 107. If the CPU 101 determines in step S501 that image data has been recorded on the recording medium 107, the process proceeds to step S502.

  In step S <b> 502, the CPU 101 displays a list of thumbnails of the most recently recorded image data among the image data recorded on the recording medium 107 on the display unit 105. For example, the display is as shown in FIG. Thereafter, the process proceeds to step S504.

  On the other hand, if the CPU 101 determines in step S501 that no image data is recorded on the recording medium 107, the process proceeds to step S503.

  In step S <b> 503, the CPU 101 controls the display unit 105 to display that the image data is not recorded on the recording medium 107. Thereafter, the process proceeds to step S504.

  In step S504, the CPU 101 determines whether or not the power button 202 has been pressed, or whether or not the operation unit 106 has not accepted an operation for a certain period of time. In step S504, when the CPU 101 determines that the power button 202 has been pressed or the operation unit 106 has not accepted an operation for a certain period of time, this process ends, and the process returns to the process of FIG. Otherwise, the process proceeds to step S505.

  In step S505, the CPU 101 determines whether or not the release switch has been pressed. If the CPU 101 determines in step S505 that the release switch 203 has been pressed, the process proceeds to the above-described shooting process. On the other hand, if the CPU 101 determines in step S505 that the release switch 203 has not been pressed, the process proceeds to step S506.

  In step S <b> 506, the CPU 101 determines whether an instruction to display image data is received via the operation unit 106. If it is determined in step S506 that an instruction to display image data has not been received, the process proceeds to step S510. Step S510 will be described later. On the other hand, if it is determined in step S506 that the CPU 101 has received an instruction to display a list of photographed image data, the process proceeds to step S507.

  In step S507, the CPU 101 controls to display a list of thumbnails of the image data recorded on the recording medium 107 on the display unit 105. For example, the display is as shown in FIG. Thereafter, the process returns to step S504.

  If it is determined in step S506 that the CPU 101 has received an instruction to display one side of the captured image data, the process advances to step S508.

  In step S508, the CPU 101 accesses the recording medium 107 to read the image data specified by the instruction received in step S506.

  Next, in step S509, the CPU 101 controls to display the image data read in step S508 on the display unit 105. For example, the display is as shown in FIG.

  In step S <b> 510, the CPU 101 receives an instruction to delete the currently displayed image data via the operation unit 106.

  If CPU 101 determines in step S510 that it has not received an instruction to delete the displayed image data, the process returns to step S504. On the other hand, if it is determined in step S510 that the CPU 101 has received an instruction to delete the displayed image data, the process proceeds to step S511.

In step S511, the CPU 101 deletes the displayed image data. Thereafter, the process returns to step S501.
The above is the description of the operation of the digital camera 100 in the reproduction process.

  Next, the end preparation process will be described with reference to FIG. FIG. 7 is a flowchart showing the operation of the digital camera 100 in the end preparation process.

  First, in step S701, the CPU 101 determines whether or not the logging function is set to ON. Specifically, the CPU 101 makes a determination with reference to the on / off information of the logging function recorded in the nonvolatile memory 103. If the CPU 101 determines in step S701 that the logging function is not set to ON, the process proceeds to step S702. On the other hand, if the CPU 101 determines in step S701 that the logging function is set to ON, the process proceeds to step S703.

  In step S <b> 702, the CPU 101 stops power supply to each unit of the digital camera 100. Thereafter, this process ends, the process returns to the process of FIG. 3, and the digital camera 100 is turned off.

  On the other hand, when the logging function is on, the logging process is performed in response to the power of the digital camera 100 being switched from the on state to the off state by pressing the power button in the shooting mode or the playback mode. Is started.

  In step S703, the CPU 101 notifies the user that logging processing is to be performed after the power is turned off. For example, the display unit 105 is controlled to display a message such as the display 206 in FIG. By this display, the user can know that the logging process is performed even after the power button is pressed, and an unexpected situation such as the battery being exhausted without the user's knowledge can be prevented. Thereafter, the process proceeds to step S704.

In step S <b> 704, the CPU 101 stops supplying power to each unit of the digital camera 100 except the time measuring unit 110, and the digital camera 100 is turned off from the power on state. Note that the power-on state in the present embodiment refers to a state in which power is supplied to the CPU 101. On the other hand, the state in which the power is off in the present embodiment refers to a state in which no power is supplied to the CPU 101. Thereafter, the process proceeds to the logging process shown in the flowchart of FIG.
In the foregoing, the operation of the digital camera 100 in the shooting mode and the playback mode has been mainly described.

  Next, the logging process will be described. FIG. 6 is a flowchart showing the operation of the digital camera 100 in the logging process. The processing shown in this flowchart is realized by the CPU 101 and the time measuring unit 110 working together to control each unit of the digital camera 100.

  When the logging function is set to ON, the processing shown in this flowchart is started in response to the power of the digital camera 100 being turned off by pressing the power button 202 in the shooting mode or the playback mode. The

  First, in step S601, the time measuring unit 110 counts a certain time. Meanwhile, the digital camera 100 stands by with the power off. When the count for a certain time is completed, the process proceeds to step S602.

  In step S602, the time measuring unit 110 controls to supply power to devices necessary for the positioning process including the CPU 101 and the GPS 108.

  Next, in step S603, the CPU 101 determines whether or not the remaining amount of the battery has become a certain amount or less. If the CPU 101 determines in step S603 that the remaining battery level has fallen below a certain level, the process ends. If the CPU 101 determines in step S603 that the remaining battery level is not below a certain level, the process advances to step S605.

  In step S605, the CPU 101 performs a positioning process using the GPS 108 and controls to acquire position information.

  In step S606, the CPU 101 determines whether or not position information has been acquired in step S605. If the CPU 101 determines that position information has not been acquired, the process proceeds to step S609. If the CPU 101 determines that the position information has been acquired, the process proceeds to step S607.

  In step S607, the CPU 101 determines whether or not the free capacity of the recording medium 107 is greater than or equal to the capacity necessary for recording the position information acquired in step S605. That is, it is determined whether or not position information can be recorded on the recording medium 107. If the CPU 101 determines in step S607 that the position information can be recorded on the recording medium 107, the process proceeds to step S608. If the CPU 101 determines in step S607 that the position information cannot be recorded on the recording medium 107, the process is terminated.

  In step S608, the CPU 101 performs position recording processing for recording the position information acquired in step S605 on the recording medium 107 as a log file. At this time, if the CPU 101 determines that the log file for recording the position information is not recorded in the recording medium 107, a new log file is generated and the position information is recorded in the log file. Thereafter, the process proceeds to step S609.

  In step S609, the CPU 101 stops power supply to each unit of the digital camera 100, and the process returns to step S601.

In this flow, pressing of the power button 202 or the play button 204 is accepted as an interrupt process. When the CPU 101 accepts the pressing of the power button 202 or the playback button 204, this process ends, and the process moves to FIG.
The above is the description of the operation of the digital camera 100 in the logging process.

  As described above, the imaging apparatus that does not record the position information on the recording medium as the log file when the imaging process is executed has been described.

  The logging process in the digital camera 100 described above is not executed in parallel with the shooting process. Thus, during execution of the photographing process, control is performed so that the process of accessing the recording medium 107 in order to record the position information as a log file is not executed. Thereby, it is possible to prevent the recording of the image data by the photographing process from being hindered by the recording of the position information by the logging process.

[Second Embodiment]
In the first embodiment, the imaging apparatus that does not execute the imaging process and the logging process in parallel has been described. In the first embodiment, the positioning process is not performed during the execution of the imaging process. That is, the position information obtained at the shooting timing cannot be added to the shot image data.

  On the other hand, in the second embodiment, a shooting position acquisition process that is a process different from the logging process is executed in parallel with the shooting process. In the shooting position acquisition process, the position information acquired periodically is recorded in the work memory 104, and the position information is read from the work memory 104 and added to the shot image data when the shooting operation is performed. It was decided to.

  Since this embodiment has many parts in common with the first embodiment, the description will focus on parts specific to this embodiment.

First, the imaging position acquisition process will be described with reference to FIG.
FIG. 8 is a flowchart showing the operation of the digital camera 100 regarding the photographing position acquisition process. The process shown in this flowchart is started in parallel when the process of FIG. 3 is started.

  Note that the processing shown in the flowchart of FIG. 8 is executed in parallel with the processing shown in FIG. 3, FIG. 4, FIG. 5, and FIG.

  First, in step S801, the CPU 101 determines whether or not the digital camera 100 is in a power-off state. If the CPU 101 determines in step S801 that the power is on, the process ends. On the other hand, if the CPU 101 determines in step S801 that the power is off, the process proceeds to step S802.

  In step S802, the time measuring unit 110 measures a certain time. During this time, the GPS 108 does not perform positioning processing.

  Next, in step S <b> 803, the CPU 101 performs a positioning process using the GPS 108 and controls to acquire position information.

  In step S804, the CPU 101 determines whether position information has been acquired in step S803. If the CPU 101 determines that position information has not been acquired, the process returns to step S801. If the CPU 101 determines that the position information has been acquired, the process proceeds to step S805.

In step S805, the CPU 101 records the position information acquired in step S803 in the work memory 104. In the present embodiment, the position information to be recorded in the work memory 104 is one, and if the position information has already been recorded in the work memory 104, the position information acquired in step S803 is overwritten. This process is performed in order to associate the position information recorded in the work memory 104 by this process with the image data in the imaging process in the present embodiment described later.
The above is description of operation | movement of the digital camera 100 in the process regarding the positioning process of this embodiment.

  Next, photographing processing in the present embodiment will be described with reference to FIG. FIG. 9 is a flowchart showing the operation of the digital camera 100 in the photographing process in the present embodiment. In this embodiment, in step S302 of FIG. 3, the process shown in FIG. 9 is performed instead of the process shown in FIG.

  The processing from step S901 to step S907 is the same as the processing from step S401 to step S407 in FIG.

  In step S908, the CPU 101 reads position information recorded in the work memory 104. This position information is the position information recorded in step S803 in FIG.

Next, in step S909, the CPU 101 stores the position information read in step S908 in the recording medium 107 in association with the image data acquired in step S904. Thereafter, the process returns to step S901.
The above is the description of the operation of the digital camera 100 in the photographing process in the present embodiment.

  As described above, the example in which the position information is recorded in the work memory 104 and is not recorded as a log file on the recording medium 107 during the execution of the photographing process has been described.

  With this configuration, the digital camera 100 according to the present embodiment performs the positioning process during the shooting process, but does not record the positioning result in the work memory 104 without recording the log file in the recording medium 107. Record. Thereby, it is possible to prevent contention with the process of recording the image data on the recording medium 107. On the other hand, when shooting is performed, the position information recorded in the work memory 104 is used to associate the position information with the image data. With this process, it is possible to associate the position information with the captured image data while suppressing the occurrence of unexpected competition.
