Description

  The present invention relates to control of adding position information to an image file in which a plurality of scenes are recorded in one file, and management of the image file.

  It is possible to record a plurality of scenes (each scene may be a short moving image or a still image) in one file and create a new moving image file, for example. Consider adding position information to each scene in this video file.

  In recent years, a method of controlling the addition of image position information in consideration of privacy has been known. It is determined whether or not the content is related to privacy, and when there is content related to privacy, recording of location information on an image is not performed or use of location information is restricted (see Patent Document 1). .

JP 2010-081428 A

  In Patent Document 1, it is assumed that only one piece of position information is recorded for one piece of image data. Therefore, in the case of a moving image file including position information in each of a plurality of scenes, there is a problem that only position information can be left or deleted. That is, when controlling the addition of position information to a moving image file in which a plurality of scenes are recorded in one file, there is a problem that it is not possible to flexibly control the addition of position information.

  In order to eliminate the above problems, the imaging apparatus of the present application includes a recording control unit that controls to record a plurality of scene images obtained by the imaging unit as a single image file on a recording medium, and a scene image. It has an acquisition means for acquiring position information at the time of shooting and a determination means for determining whether or not position information can be recorded for each scene, and the recording control means determines that the determination means records position information. The plurality of position information acquired by the acquisition means are collectively recorded in association with the image file.

  Even when the addition of position information to an image file in which a plurality of scenes are recorded in one file is controlled, the addition of position information can be controlled flexibly.

When the imaging apparatus is in the moving image shooting mode and enters the range where position information is not added, a message indicating that position information associated with the scene image is not added is displayed in the screen 601 of FIG. By viewing this message, the user can know that position information is not added to the captured image. As a method for indicating to the user that the position information is not added to the image of the scene after shooting, a lamp such as an LED is mounted on the imaging device and the lamp is turned on to notify the user. You may take a method.

  In the following, a process for controlling the addition of position information by the imaging apparatus 100 at the time of capturing an image of a scene will be described with reference to FIG.

  In step S701, it is determined whether it is the first scene image. If it is the first scene image, the process proceeds to step S702. If it is determined that it is not the first scene image, the process proceeds to step S703.

  In step S702, the moving image file is initialized.

  In step S703, the current position is acquired. Here, the current position is acquired from the position information acquisition device 111 of the imaging device 100.

  In step S704, a distance D from the position of the table of FIG. 5 recorded in advance in the imaging apparatus 100 to the current position is calculated. The method for obtaining the distance between two points whose latitude and longitude are known will be described below.

For example, the table position (point A) recorded in advance is assumed to be 50 ° 45 ′ north latitude and 130 ° 12 ′ east longitude, and the current position (point B) is 50 ° 34 ′ north latitude and 129 ° 58 ′ east longitude. If the difference in the latitude direction is Δny and the difference in the distance in the longitude direction is Δnx,
Δny = 11 ′ → 0.183 °
Δnx = 14 ′ → 0.233 °
It is.

Assuming that the earth is a perfect sphere, let the radius of the earth be R (= 6378 km). The distance difference in the longitude direction is Δy, and the distance difference in the longitude direction is Δx. Δy and Δx are obtained by the following equations.
Δy = 0.183 ° / 360 ° × 2πR = 20.37 km
Δx = 0.233 ° / 360 ° × 2πR = 25.94 km

  If the distance between the two points AB is Δd, Δd can be obtained by the following equation.

  In step S705, it is compared whether the distance D obtained in step S704 is smaller than the radius registered in the table.

  If it is determined in step S705 that the radius is larger than the radius registered in the table of FIG. 5, the process proceeds to step S706. If it is determined in step S705 that the radius is equal to or smaller than the radius registered in the table, the process proceeds to step S707.

  In step S706, it is determined whether the end of the table of FIG. If it is determined in step S706 that the check has been completed, the process proceeds to step S708. If it is not determined in step S706 that the end of the table has been checked, the process returns to step S704 to check the next table. Repeat for the number of positions registered in the table.

  In step S707, empty data is recorded in the moving image file as position information. Specifically, it is filled with all zeros. After the process of step S707, the process proceeds to step S709.

  In step S708, the position information is recorded in the moving image file.

  In step S709, the number of scene images is recorded in a moving image file. It is 1 when shooting first. If it is not the first shooting, 1 is added to the number already recorded and updated.

  In step S710, the video data is recorded in a moving image file.

  In step S711, the header is updated. Update information such as the size of the video file recorded in the header.

  In this embodiment, a moving image is assumed to be captured by the imaging apparatus, but a still image may be used. It is also conceivable to shoot by switching between moving images and still images. A range where position information is not added in still image shooting is set in the imaging device, and during movie shooting, the range where position information associated with a scene image is not added is wider than the setting during still image shooting. May be. During moving image shooting, there is a possibility that the photographer moves from outside the prohibited area to the prohibited area. In such a case, it is possible to reduce the recording of position information.

  In addition, two tables are provided for setting the range of position information that should not be added during shooting for movie shooting and still image shooting, and the table used for movie shooting and still image shooting can be switched. May be. Further, the range in which position information associated with the scene image is not added may be widened according to the length of the image of the scene to be photographed. This also means that the longer the shooting time, the higher the possibility that the photographer moves from the prohibited area to the prohibited area during shooting, and it is possible to reduce the occurrence of location information being recorded in such a case. Become.

  As described above, addition of position information can be controlled for each scene at the time of shooting.

The second embodiment is an example of processing when distributing a moving image file to the outside, such as uploading a moving image file from an information processing device to a moving image management device. When the moving image file is distributed from the information processing apparatus, the position information is deleted from the moving image file as necessary.

  The moving image file does not need to be created by the information processing device used in this embodiment, and the moving image file is assumed to have position information associated with each scene image in advance by a device different from the information processing device. . The format of the moving image file is the same as that of the first embodiment, but it is assumed that position information corresponding to all scene images is recorded in the moving image file.
