The relative position information adding means restricts the position information of the captured moving image and adds the relative position information when it is determined that the position where no position information is added at the time of shooting is determined.

The outline of the moving image shooting apparatus of the present embodiment configured as described above will be described below.
The moving image shooting apparatus of the present embodiment includes a shooting mode for shooting a moving image, a playback mode for playing back the shot moving image, a map display mode for displaying the position information recorded at the time of shooting on the map, and a place for restricting the position information. There is a setting mode to set. Each of these modes can be switched with a button. The moving image shooting apparatus according to the present embodiment starts in the shooting mode when the power is turned on.

The structure of a moving image file created by the moving image shooting apparatus of this embodiment will be described with reference to FIG.
FIG. 12A shows a file structure of a moving image with position information. This is a moving image file in which position information and relative position information are recorded and position information is not limited. From the top of the file, the header, manufacturer-specific information, one or more video frame data, and one or more audio sample data are arranged. The manufacturer-specific information includes position information, one or more relative position information, one or more landmark information and its relative position information, and one or more private metadata. The relative position information is a difference between two pieces of position information. Note that the same configuration as that for calculating the difference is possible by using data on the movement distance obtained from an acceleration sensor, a gyro sensor, a magnetic sensor, or the like instead of the difference in position information.

  In the present embodiment, the following contents are recorded in the manufacturer-specific information. In the relative position information of the manufacturer specific information, a difference in position information from the top frame is recorded with respect to the top frame. As the landmark information and its relative position information, the relative position information corresponding to the name of the landmark is recorded as a set.

  As the relative position information of the landmark information, a difference in position information with respect to the first frame is recorded. Private metadata records relative position information corresponding to a home location as a set. In addition, if there exists a place decided as metadata of a moving image file, you may put position information there. Further, it may be placed in a user area prepared for each frame of video data.

  FIG. 12B shows a file structure of a moving image with relative position information. This is a moving image in which position information is deleted and only relative position information is obtained when position information is restricted. From the top of the file, the header, manufacturer-specific information, one or more video frame data, and one or more audio sample data are arranged. The manufacturer-specific information includes one or more relative position information, one or more landmark type information, and its relative position information.

  In the present embodiment, the following contents are recorded in the manufacturer-specific information. In the relative position information of the manufacturer specific information, a difference in position information from the top frame is recorded with respect to the top frame. As the landmark type information and its relative position information, the relative type information corresponding to the landmark type information is recorded as a set. As the relative position information of the landmark type information, a difference in position information with respect to the first frame is recorded.

  FIG. 12C shows the file structure of the position information restoration moving image used in the second embodiment to be described later. FIG. 12B has a structure in which position information is added. From the top of the file, the header, manufacturer-specific information, one or more video frame data, and one or more audio sample data are arranged. The manufacturer-specific information is arranged in the order of position information, one or more relative position information, one or more landmark type information, and its relative position information. The method of entering the manufacturer-specific information data is the same as in FIGS. 12 (a) and 12 (b).

The moving image shooting apparatus of the present embodiment acquires position information with the GPS receiver 107 when starting moving image shooting, and records the position information at the start of moving image shooting in the position information area of the manufacturer-specific information.
When shooting of a moving image is started, position information is acquired by the GPS receiver 107 every minute, and a difference from the position information at the start of moving image shooting is calculated. The calculated differences are recorded one after another in the relative position information area of the manufacturer specific information.

  When shooting a moving image, nearby landmark information and private metadata are automatically added from the position information acquired periodically. These pieces of information are also recorded in the landmark information of the manufacturer specific information, the relative position information area thereof, and the private metadata area of the manufacturer specific information. In this embodiment, the position information acquisition interval is 1 minute, but it can be acquired from a configuration in which the operator sets an arbitrary interval or a moving distance detected using an acceleration sensor, gyro sensor, magnetic sensor, or the like. A configuration may be used in which the acquisition interval is set based on the moving distance using data.

In the present embodiment, an example of setting a location where position information is restricted in the setting mode and shooting a moving image in the shooting mode, and a display screen when the shot moving image is displayed in the map display mode are shown. The moving image shooting program is activated in the setting mode and shooting mode of the moving image shooting device. The operator can switch to the setting mode and the shooting mode by operating the operation unit 105.
Here, an operation in which the operator operates the operation unit 105 to switch to the setting mode and sets a place where the position information is restricted will be described with reference to FIGS.

When the operator operates the operation unit 105 to switch to the setting mode, the control unit 101 in FIG. 1 displays a screen 210 in FIG. 2 for setting a place for restricting position information on the display unit 106.
On the screen 210 in FIG. 2, position information measured by the GPS receiver 107 is displayed. In this embodiment, the present location is acquired as 35 degrees 35 minutes north latitude and 139 degrees 40 minutes 00 seconds east longitude.

In FIG. 2, reference numeral 220 denotes an input field for inputting a range for limiting position information. In this embodiment, the operator operates the operation unit 105 and inputs 100.
Reference numeral 230 denotes an OK button that the operator operates and presses the operation unit 105 when the range is determined by a value input to 220. In the present embodiment, a radius of 100 m from the current location is set as a prohibited range for limiting position information.
Reference numeral 240 denotes a Cancel button that the operator operates and presses the operation unit 105 when canceling an operation for setting a range for limiting position information.

  The flowchart of FIG. 3 is a flowchart illustrating a processing flow for setting a range for limiting position information. This flowchart starts when the operator operates the operation unit 105 to switch to the setting mode. When the processing flow for setting the range for limiting the position information is completed, the shooting mode is automatically set.

In step S <b> 301, the control unit 101 acquires position information acquired from the GPS receiver 107.
In step S <b> 302, the control unit 101 displays the screen 210 on the display unit 106. The current location acquired in S301 is also displayed in a superimposed manner.
In step S <b> 303, the control unit 101 acquires a value input by the operator to 220.
In step S304, the control unit 101 determines whether the operator has pressed the 240 Cancel button. If it is determined that the Cancel button has been pressed, the setting mode is terminated and the photographing mode is entered. If it is determined that the Cancel button has not been pressed, the process proceeds to S305.

  In step S305, the control unit 101 determines whether the operator has pressed the 230 OK button. If it is determined that the OK button has been pressed, the process proceeds to S306. If it is determined that the OK button has not been pressed, the process proceeds to S301.

In step S306, the control unit 101 sets a position information recording prohibited range from the values acquired in steps S301 and S303. The value set here is recorded in the RAM 103.
The range for limiting the position information may be an arbitrary rectangular range or an arbitrary place name. The range for limiting the position information may be configured not only to set from the current location but also to specify an arbitrary location. Although the configuration is such that only one range for limiting the position information is set, a configuration in which a plurality of locations are stored in a table and a plurality of ranges can be limited may be used.

  Here, it is determined whether or not the position information is within the range for limiting the position information while shooting the moving image in the shooting mode of the moving image shooting apparatus of the present embodiment. The operation of converting to the above will be described with reference to the flowcharts of FIGS.

  In step S <b> 401, the control unit 101 acquires a position information recording prohibited range from the RAM 103. In the present embodiment, the position information recording prohibition range is set to a radius of 100 m centering on north latitude 35 degrees 35 minutes 00 seconds and east longitude 139 degrees 40 minutes 00 seconds.

In step S <b> 402, the control unit 101 initializes a restriction flag for position information used for determining whether or not a place where position information needs to be restricted is entered during moving image shooting.
In step S <b> 403, the control unit 101 acquires position information from the GPS receiver 107. Position information corresponding to the first frame of the moving image recording is acquired.

In step S404, the control unit 101 records position information corresponding to the first frame of the moving image recording acquired in step S403. The recording location is recorded in the position information area of the manufacturer specific information of the moving image file.
In step S405, the control unit 101 determines whether the position information acquired in steps S403 and S408 is within the recording prohibited range of the position information acquired in step S401. When it is determined that the position information is in the recording prohibited range, the process proceeds to S406. If it is determined that the position information is not within the recording prohibited range, the process proceeds to S407.

In step S406, the control unit 101 sets the position information restriction flag to On. By referring to this flag, it is determined whether or not to limit the position information.
In step S407, the control unit 101 records a moving image. The moving image is recorded in the video frame data area and the audio sample data area of the file.

In step S <b> 408, the control unit 101 acquires position information from the GPS receiver 107.
In step S409, the control unit 101 converts the position information acquired in step S408 into relative position information. The relative position information is calculated as a difference between the position information acquired in S408 and the position information acquired in S403.

In S410, the control unit 101 records the relative position information converted from the position information in S409. The relative position information is recorded in the relative position information area of the manufacturer specific information of the moving image file.
In step S411, the control unit 101 determines whether a moving image shooting end instruction has been received from the operator. If it is determined that there is an instruction to end moving image shooting, the process proceeds to S412. If it is determined that there is no instruction to end moving image shooting, the process proceeds to S405.

By repeating S405 to S411, recording of relative position information and recording of moving images are performed.
In step S412, the control unit 101 determines whether the position information restriction flag is On. When the restriction flag of the position information is On, the process proceeds to S413. If the position information restriction flag is not On, the processing flow ends.
In step S <b> 413, the control unit 101 performs processing for limiting the position information, landmark information, and private metadata recorded in the moving image. Details will be described with reference to the flowchart of FIG.

The flowchart in FIG. 5 is a processing flow for restricting position information, landmark information, and private metadata recorded in a moving image.
In this embodiment, by outputting the position information / landmark information recorded in the moving image and its relative position information / private metadata to the log file, the original information before the restriction is saved. The data structure of the log file is not particularly illustrated. The position information / landmark information and its relative position information / private metadata information are extracted as they are.

  The log file of this embodiment is a file in which the extension of the moving image is changed to .log. By making the log file a file in which another extension of the moving image file is changed, it is possible to associate the moving image file with the log file. In addition, you may make it the structure recorded on the database linked | related with the file instead of a log file.

In step S501, the control unit 101 records the position information recorded in the moving image in a log file associated with the moving image.
In step S502, the control unit 101 records the landmark information recorded in the moving image in a log file associated with the moving image.

In step S503, the control unit 101 records private metadata recorded in the moving image in a log file associated with the moving image.
In step S504, the control unit 101 restricts the position information recorded in the moving image. In this embodiment, the position information recorded on the moving image is deleted.

In step S505, the control unit 101 converts the landmark information recorded in the moving image into a landmark type. In this embodiment, information including detailed names such as XX parks and △ □ lakes is converted into types of parks and lakes.
In step S506, the control unit 101 deletes the private metadata recorded in the moving image. Private metadata in this embodiment is home and home location information.

Here, a display example of a captured moving image file will be described.
FIG. 6 illustrates a screen when a moving image is reproduced in the map display mode of the moving image capturing apparatus of the present embodiment. FIG. 6A shows a screen on which a moving image with position information that does not limit position information is displayed. FIG. 6B shows a moving image screen with relative position information in which position information is limited.

Description will be made regarding screens 601 to 605 of the moving image with position information in FIG.
In FIG. 6A, reference numeral 601 denotes a map screen on which position information, landmark information, and private metadata at the time of moving image shooting are displayed.
Reference numeral 602 denotes a moving route obtained from position information at the time of moving image shooting. S and E marks are displayed at the shooting start position and shooting end position of the moving image, respectively.

Reference numeral 603 denotes landmark information recorded in the moving image file from position information at the time of moving image shooting. In the present embodiment, landmark information called xx park is set.
Reference numeral 604 denotes landmark information recorded in the moving image file from position information at the time of moving image shooting. In the present embodiment, landmark information “Δ □ lake” is set.
Reference numeral 605 denotes private metadata recorded in a moving image file from position information at the time of moving image shooting. In this embodiment, home metadata is set.

  Since 601 to 605 in FIG. 6A do not restrict the position information, all the information is recorded and the information about the home and its surroundings can be understood well. Further, from the position information, it is possible to know the moving route, which place the user has stayed for a long time, and which place is the moving image that has just passed through. Further, by analyzing the position information and the time when the position information was recorded, the speed at the time of movement, the moving distance, etc. can be known.

A description will be given of 606 to 609 of the moving image screen with relative position information in FIG.
Reference numeral 606 denotes a map screen on which relative position information and landmark type information are displayed because position information at the time of moving image shooting has been deleted. Note that the map is not displayed even in the map display mode because the position information has been deleted.

Reference numeral 607 denotes relative position information at the time of moving image shooting. S and E marks are displayed at the shooting start position and shooting end position of the moving image, respectively.
Reference numeral 608 denotes landmark type information. Since the landmark information is limited, the landmark type information is displayed. In the present embodiment, it is possible to know that the vicinity of the park has been strolled from the relative position information.
Reference numeral 609 denotes landmark type information. Since the landmark information is limited, the landmark type information is displayed. In this embodiment, it can be known from the relative position information that the vehicle has passed by the lake.

  6B to 609 in FIG. 6B can know, from the relative position information, the moving route, which place it has stayed for a long time, and which place is a moving image that has just passed through. Further, by analyzing the relative position information and the time when the relative position information is recorded, it is possible to know the moving speed, the moving distance, and the like.

  In the present embodiment, the position information converted into the relative position information is periodically recorded. However, when the acquired position information is recorded as it is and the position information is limited, the position information may be converted into the relative position information. .

  Although the position information is deleted after the photographing is finished, the position information may be restricted by including place name (prefecture name) information or the like instead of the position information. In this embodiment, it is determined whether or not the recording prohibition range is entered after the photographing is completed and the position information is deleted. However, the position information recorded later by the PC application or the like falls within the range where the position information is restricted. The position information may be limited by determining whether the position information is present. Further, the position information may be restricted by reducing the accuracy of the position information.

  With the above processing, when entering a certain range where no position information is added during moving image shooting, the position information recorded in the moving image file during moving image shooting is deleted. The landmark information is converted into landmark type information. Private metadata is deleted. By these processes, information obtained from the moving image file is limited in consideration of privacy. Further, it is possible to leave information on the movement route, speed, and distance obtained from a plurality of relative position information while limiting the position information.
