FIG. 3 is a flowchart illustrating an example of the peripheral camera selection process of the video camera 100.
When the user operates the operation unit 202 of the video camera 100, the control unit 200 starts a peripheral camera selection process described below. The state of the video camera 100 before starting the peripheral camera selection process may not be stored in the storage medium 210 as long as the subject is captured from the imaging unit 207. Hereinafter, a state in which a subject is captured from the imaging unit 207 and is not stored in the storage medium 210 is assumed to be during imaging, and a state stored in the storage medium 210 is referred to as imaging.
In addition, it is necessary to set the maximum number of video cameras 101 to 109 in the vicinity of the video camera 100 (hereinafter, the maximum number of selected cameras) before the start of the peripheral camera selection process. The maximum camera selection number can be set by the user operating the operation unit 202. In the present embodiment, description will be made assuming that 4 is set as the maximum number of selected cameras.

In step S300, the control unit 200 transmits a wireless connection establishment request to the surrounding video cameras 101 to 109 via the communication unit 205, establishes the wireless connection, and proceeds to step S301. In the present embodiment, it is assumed that wireless parameters such as an IP address are preset in the video cameras 100 to 109 and held in the storage unit 206.
In step S301, the control unit 200 stores the orientation (orientation information) and position (position information) of the video camera 100 detected by the orientation detection unit 203 and the position detection unit 204 of the video camera 100 in the storage unit 206 as a data list. Yes (internal information acquisition). Then, the control unit 200 proceeds to step S302. The data list will be described later. The data list is an example of internal information.
In step S <b> 302, the control unit 200 transmits an acquisition request for position information and orientation information to the video cameras 101 to 109 that are wirelessly connected via the communication unit 205. The control unit 200 acquires position information and orientation information (external information acquisition) from each of the video cameras 101 to 109, stores the information in the storage unit 206 as a data list, and proceeds to step S303. The data list will be described later. The data list is an example of external information.

In step S303, the control unit 200 extracts from the video cameras 101 to 109 the video camera that is shooting the vicinity of the same subject as the video camera 100 in the subject determination unit, and proceeds to step S304. Details of the processing of the subject determination unit will be described with reference to FIG.

Proceed to step S305. Details of the processing of the selection unit will be described with reference to FIG.
In step S305, the control unit 200 transmits a representative image acquisition request to the video camera extracted in step S304 via the communication unit 205. The control unit 200 acquires the file name of the video data including the representative image and the video of the representative image from each video camera, holds the file name in the storage unit 206, and proceeds to step S306. The representative image is desirably an image when the acquisition of the representative image is inquired, but may be an image of a predetermined time before (for example, 5 seconds before). Note that the control unit 200 may acquire a moving image obtained from the imaging unit 207 instead of the representative image.

In step S306, the control unit 200 displays the representative image acquired in step S305 on the display unit 201, and proceeds to step S307.
FIG. 4 is a diagram illustrating an example of display on the display unit 201 of the video camera 100 in step S306. An image 900 is an image obtained from the imaging unit 207 of the video camera 100. Representative images 901, 902, 903, and 904 are extracted representative images of the video cameras among the surrounding video cameras 101 to 109. The video camera 100 can display a list of extracted representative images of the video camera on the display unit 201 on the display unit 201.
In step S307, it is determined whether or not the user operates the operation unit 202 to select the representative image displayed in step S307. If the representative image is selected by the user, the control unit 200 proceeds to step S308, otherwise proceeds to step S309. In step S307, since the user selects the representative image, the control unit 200 waits for a predetermined time until the process proceeds to the next step.

In step S308, the control unit 200 transmits a video data acquisition request to the video camera corresponding to the representative image selected in step S307 via the communication unit 205. At that time, the control unit 200 also transmits the file name of the video data including the video of the representative image acquired in step S304 to the video camera. The control unit 200 acquires the video data of the file name transmitted from the video camera 100 from the video camera corresponding to the representative image, stores it in the storage medium 210, and proceeds to step S309 when the processing is completed. Note that the control unit 200 may store the video camera corresponding to the representative image and the file name of the video data in the storage unit 206, and the video data may be acquired later.
In step S309, the control unit 200 displays on the display unit 201 an inquiry as to whether or not to continue the peripheral camera selection process. The user operates the operation unit 202 to select whether to end the peripheral camera selection process. If the control unit 200 determines that the user has selected to end, the control unit 200 proceeds to step S310, otherwise proceeds to step S301.
In step S310, the control unit 200 transmits a wireless connection disconnection request to the surrounding video cameras 101 to 109 via the communication unit 205, and confirms the disconnection of the wireless connection with the video cameras 101 to 109, as shown in FIG. The processing shown in FIG.

FIG. 5 is a flowchart illustrating an example of information processing of the video cameras 101 to 109 according to the first embodiment.
The state of the video cameras 101 to 109 before proceeding to step S400 may be any state during shooting, imaging, or playback as long as the power is on. In the following, in FIG. 5, description will be made assuming that the control unit 200 of the video cameras 101 to 109 performs processing based on a program.
In step S400, the control unit 200 determines whether a wireless connection establishment request has been received from another video camera (video camera 100). The control unit 200 proceeds to step S401 if a wireless connection establishment request is received, and proceeds to step S400 otherwise. The video cameras 101 to 109 receive the wireless connection establishment request when the video camera 100 in step S300 transmits the wireless connection establishment request.
In step S401, the control unit 200 establishes a wireless connection with the video camera 100, and proceeds to step S402. The process in step S401 is performed simultaneously with the establishment of the wireless connection in step S300.

In step S <b> 402, the control unit 200 determines whether a wireless connection disconnection request has been received from the video camera 100. If the control unit 200 has received a wireless connection disconnection request, the process proceeds to step S412; otherwise, the process proceeds to step S403. Receiving the wireless connection disconnection request is performed when the video camera 100 in step S310 transmits a wireless connection disconnection request.
In step S <b> 403, the control unit 200 determines whether a request for acquiring position information and orientation information has been received from the video camera 100. The control unit 200 proceeds to step S404 if a request for acquisition of position information and orientation information has been received, and proceeds to step S402 if not. The reception request for the position information and orientation information is received when the video camera 100 in step S302 transmits the acquisition request for position information and orientation information.
In step S404, the control unit 200 determines whether or not shooting is currently being performed. The control unit 200 proceeds to step S405 if shooting is in progress, otherwise proceeds to step S406. In the determination in step S404, the control unit 200 may determine whether or not the image was captured a certain time before (for example, 5 seconds before). It may be determined whether there is video data that can be transmitted to the camera 100.

In step S405, the control unit 200 stores the position information and direction information of the video camera detected by the direction detection unit 203 and the position detection unit 204 of each video camera in the storage unit 206 as a data list, and the process proceeds to step S407.
In step S406, the control unit 200 transmits invalid data (for example, 0 data) to the video camera 100, and the process proceeds to step S408.
In step S407, the control unit 200 transmits the position information and orientation information to the video camera 100, and the process proceeds to step S408.
In step S <b> 408, the control unit 200 determines whether a representative image acquisition request is received from the video camera 100. If the control unit 200 has received a representative image acquisition request, the process proceeds to step S409; otherwise, the process proceeds to step S410. The reception of the representative image acquisition request is performed when the video camera 100 in step S305 transmits the representative image acquisition request.
In step S409, the control unit 200 transmits one image data obtained from the imaging unit 207 as a representative image to the video camera 100, and proceeds to step S410. The representative image may be image data obtained from the imaging unit 207 when a representative image acquisition request is received or image data of a predetermined time before (for example, 5 seconds before).

In step S410, the control unit 200 determines whether a video data acquisition request and a video data file name have been received from the video camera 100. If the video data acquisition request and the video data file name have been received, the control unit 200 proceeds to step S411, otherwise proceeds to step S402. The video data acquisition request and the video data file name are received when the video camera 100 in step S308 transmits the video data acquisition request and the video data file name.
In step S411, the control unit 200 searches the storage medium 210 for the file name of the video data received in step S410, transmits the video data having the same file name in the storage medium 210 to the video camera 100, and proceeds to step S402. .
In step S412, the control unit 200 disconnects the wireless connection with the video camera 100, transmits to the video camera 100 that the disconnection is completed, and ends the process illustrated in FIG.

  FIG. 6 is a diagram in which information such as the position and orientation of the video camera and the position of the subject are added to the system configuration diagram of FIG. A position 500 is the position of the video camera 100. The arrow from the position 500 is the direction of the video camera 100. Positions 501 to 509 are positions of the video cameras 101 to 109, respectively. The arrows from the positions 501 to 509 are the directions of the video cameras 101 to 109, respectively. Assume that each video camera is shooting in the direction of the arrow. A position 510 is the position of the subject 110. The locations 511 to 515 are approximate locations. A place 511 is a place where the video camera 100 is located. A place 512 is a place where the video cameras 101 to 103 are located. A place 513 is a place where the video camera 104 is located. A place 514 is a place where the video cameras 105 to 107 are located. A place 515 is where the video cameras 108 and 109 are located. In FIG. 6, it is assumed that a video camera other than the video camera 107 is shooting the subject 110.

FIG. 7 is a diagram showing an example of a data list in which position information and orientation information of the video cameras 100 to 109 are collected using FIG. 6 as an example. Orientation information is expressed in directions such as east-southeast and northeast. This data list is generated in step S301 and step S302 and held in the storage unit 206.
The subject determination unit extracts a video camera shooting the same subject as the video camera 100 based on the data list.

FIG. 8 is a flowchart illustrating an example of information processing of the subject determination unit. Here, the position and orientation of each video camera are taken as two-dimensional coordinates (X, Y).
In step S700, the subject determination unit determines the position 500 of the video camera 100 as coordinates (0, 0), determines a half line (a half line having an end at the position 500) in the direction from there, and proceeds to step S701. The direction of the video camera 100 is east-southeast from the data list, and a half line having an end at the position 500 is Y = tan (337.5 °) × X (X> = 0). In this embodiment, the direction is considered as 16 directions. The azimuth interval is 22.5 °.
In step S <b> 701, the subject determination unit starts from the relative positions of the video cameras 101 to 109 when the position of the video camera 100 is the coordinates (0, 0) in the direction of the respective straight lines (ends at positions 501 to 509). And the process proceeds to step S702. For example, it is assumed that the position 501 of the video camera 101 is −1 m away from the position 500 of the video camera 100 and −3 m away from the Y direction. Then, since the direction is northeast (45 °), the half line having an end at the position 501 becomes Y = tan (45 °) × X−3 + tan (45 °) (X> = − 1).

In step S702, the subject determination unit extracts a half line intersecting with the half line having an end at the position 500, extracts a video camera corresponding to the extracted half line, and proceeds to step S703. In the example of FIG. 6, the half lines related to the video cameras 101 to 106, 108, and 109 intersect with the half line having an end at the position 500.
In step S <b> 703, the subject determination unit searches for a half line that intersects within a certain range among points where the half line having an end at the position 500 intersects, and extracts a video camera corresponding to the half line. . Then, the subject determination unit determines that the extracted video camera is a video camera shooting the subject, and ends the processing shown in FIG. In the example of FIG. 6, a half line having ends at positions 501 to 505, 508, and 509 intersects a half line having an end at position 500 around position 510, and only a half line having an end at position 506 is at position 500. It intersects in a different range from the half line with the end. As a result, the subject determination unit determines that the video cameras 101 to 105, 108, and 109 corresponding to the half lines having ends at the positions 501 to 505, 508, and 509 are video cameras that are shooting the same subject as the video camera 100. To do.
If the face detection unit for detecting the face information of the main subject is added to the configuration of the video camera in FIG. 2 and the face information of the main subject is added to the data list, it is possible to identify the subject captured by each video camera. The feature is understood, and the accuracy of the subject determination unit is improved. Note that the face detection unit may be implemented as hardware in the video camera, or software may be installed in the video camera, and the control unit 200 may read and execute the software.

Next, the selection unit preferentially selects a video camera having an angle different from that of the video camera 100 from the video cameras extracted by the subject determination unit.
FIG. 9 is a flowchart illustrating an example of information processing by the selection unit.
In step S800, the selection unit is a relatively close place (eg, a place where the distance between the video cameras is within a predetermined range (for example, within 1 m)) based on the position information of the video camera extracted by the subject determination unit. Are grouped together (grouped). Then, the selection unit groups all the video cameras and proceeds to step S801. In the example of FIG. 6, the selection unit groups the positions 501 to 503 with the location 512, the position 504 with the location 513, the location 505 with the location 514, and the locations 508 and 509 with the location 515. Note that the selection unit may determine a group in the range when a range to be set as one group is set in advance.
In step S801, the selection unit determines whether the number of selected video cameras has reached the set maximum camera selection number. If the maximum number of selected cameras has been reached, the process shown in FIG. 9 is terminated, otherwise the process proceeds to step S802.
In step S802, the selection unit determines whether there is a group of unselected video cameras. If there is an unselected video camera group, the selection unit proceeds to step S803; otherwise, the selection unit ends the process illustrated in FIG.

In step S803, the selection unit extracts a group of unselected video cameras, and proceeds to step S804. The selection unit extracts from a group having an angle (orientation) different from that of the video camera 100. Note that the selection unit may extract from a group within the range based on a preset angle range to be extracted. For example, when the angle range to be extracted is set to 0 ° to 180 ° with respect to the shooting direction of the video camera 100, the selection unit is within the set angle range, that is, based on the shooting direction of the video camera 100. Extract from the group that belongs to the clockwise semicircle region. According to this, when the subject being photographed by the video camera 100 is landscape, the video camera photographing the front of the subject can be preferentially extracted with the intention of the user. The selection unit sequentially extracts from the group having the closest angle to the video camera 100 based on the preset priority of the group to be extracted, or sequentially extracts from the group having the most different angle, or is closest to the subject. It is good also as extracting sequentially from a group. In addition, although the said priority demonstrated using the priority with respect to a group, the priority with respect to a video camera may be sufficient.
In step S804, the selection unit extracts only one video camera from the group extracted in step S803, and proceeds to step S801. As a method for extracting only one video camera, the one closest to the subject in the group may be used, or the video camera having the highest resolution may be used as long as information such as the resolution of each video camera can be acquired.
By the processing from step S801 to step S804, the selection unit sequentially selects video cameras. In this embodiment, an example is described in which one set is set as the set number, that is, only one video camera is extracted. However, this does not limit the present embodiment.

<Embodiment 2>
FIG. 10 is a diagram illustrating an example of a system configuration of the video camera system according to the second embodiment. Video cameras 100 to 109 having a wireless communication function are connected to the server 1000 via a network, and each video camera captures the subject 110. The server 1000 may be a centralized type constituted by one computer or a distributed type constituted by a plurality of computers. For the sake of simplification of description, unless otherwise specified in the present embodiment, the server 1000 is described as being a centralized type configured from one computer.
The server 1000 has a CPU, HDD, and the like as a hardware configuration, and the functions of the server 1000 are realized by the CPU executing processing based on a program stored in the HDD or the like.
The server 1000 is wirelessly connected to the video cameras 100 to 109 via a network. If the wireless connection is established, the server 1000 can store (upload) data transmitted from the video cameras 100 to 109 and transmit (download) data to the video cameras 100 to 109. Data of the video cameras 100 to 109 is collectively managed by the server 1000 so that data can be browsed from each video camera.

The processing of the video camera 100 is almost the same as that in FIG. 3, and only steps S300, S302, S305, S308, and S310 having differences will be described. It is assumed that the time setting of the video camera 100 is performed in advance by the user operating the operation unit 202.
In step S300, the control unit 200 establishes a wireless connection with the server 1000 via the communication unit 205, and proceeds to step S301.
In step S302, the control unit 200 acquires (downloads) the position information and orientation information of the video cameras 101 to 109 and the shooting end time from the server 1000 via the communication unit 205, and stores them in the storage unit 206 as a data list. The process proceeds to step S303. If the acquired shooting end time is before the current time, the control unit 200 sets the position information and orientation information of the data list of the corresponding video camera as invalid data.

In step S305, the control unit 200 acquires (downloads) the file name of the video data including the representative image of the video camera and the video of the representative image extracted from the server 1000 in step S304 via the communication unit 205, and the storage unit 206. Then, the control unit 200 proceeds to step S306. The representative image is desirably an image when the acquisition of the representative image is inquired, but may be an image of a predetermined time before (for example, 5 seconds before). Note that the control unit 200 may acquire a moving image instead of the representative image.
In step S308, the control unit 200 acquires (downloads) video data of the video camera corresponding to the representative image selected in step S307 from the server 1000 via the communication unit 205, stores the video data in the storage medium 210, and when finished. The process proceeds to step S309. Note that the control unit 200 may store the video camera corresponding to the representative image and the file name of the video data in the storage unit 206, and the video data may be acquired later.
In step S310, the control unit 200 disconnects the wireless connection with the server 1000 via the communication unit 205, and ends the process illustrated in FIG.

FIG. 11 is a flowchart illustrating an example of information processing of the video cameras 101 to 109 according to the second embodiment. It is assumed that the time settings of the video cameras 101 to 109 are performed in advance by the user operating the operation unit 202. Hereinafter, in FIG. 11, description will be made assuming that the control unit 200 of the video cameras 101 to 109 performs processing based on a program.
In step S1100, the control unit 200 establishes a wireless connection with the server 1000 via the communication unit 205, and proceeds to step S1101. Note that the processing in step S1100 needs to be performed before shooting, and the control unit 200 performs this processing when the power is turned on or the shooting mode is set.
In step S1101, the control unit 200 determines whether to disconnect the wireless connection with the server 1000. If it is determined that the wireless connection is to be disconnected, the control unit 200 proceeds to step S1110, otherwise proceeds to step S1102. Note that the control unit 200 performs a wireless connection when the user operates the operation unit 202 to request disconnection of the wireless connection, when the power is turned off, or when a mode other than the shooting mode (for example, a playback mode) is entered. It is determined whether or not to disconnect. That is, when the user operates the operation unit 202 to request disconnection of the wireless connection, when the power is turned off, or when the mode is changed to a mode other than the shooting mode (for example, the playback mode), the control unit 200 performs the wireless connection. Judge to disconnect.

In step S1102, the control unit 200 determines whether the user has operated the operation unit 202 to give an instruction to start shooting. If the control unit 200 determines that an instruction to start shooting has been given, the process proceeds to step S1103; otherwise, the process proceeds to step S1101.
In step S1103, the control unit 200 starts shooting, transmits (uploads) an invalid shooting end time to the server 1000 via the communication unit 205, and proceeds to step S1104.
In step S1104, the control unit 200 determines whether or not the user has operated the operation unit 202 to give an instruction to end shooting. If the control unit 200 determines that an instruction to end shooting has been given, the process proceeds to step S1109; otherwise, the process proceeds to step S1105.
In step S1105, the control unit 200 holds the position information and direction information of each video camera detected by the direction detection unit 203 and the position detection unit 204 of each video camera in the storage unit 206, and the process proceeds to step S1106.
