Description

  The present invention relates to an information processing system, a camera, an information processing terminal, and a program.

  It is widely performed to record information relating to such photographing data together with still image or moving image photographing data photographed by a digital camera. For example, using a standardized format called Exif (Exchangeable image file format), information such as shooting time and shooting location is recorded together with shooting data.

  In addition, when a digital camera that cannot acquire its own position information is used, position information is acquired from an opposite device of the digital camera such as a smartphone and used as shooting location information of shooting data.

  However, when the digital camera acquires position information from the opposite device, it is necessary to frequently communicate with the opposite device in order to acquire such information. Such communication has a problem that the battery consumption of the digital camera increases.

  In order to solve this problem, it has been proposed that a digital camera obtains position information from an opposite device at the timing of shooting (for example, Patent Document 1).

  Even when the digital camera communicates with the opposite device at the timing of shooting, communication between the digital camera and the opposite device is required every time shooting is performed. For this reason, there is a possibility that the consumption of the battery becomes large. On the other hand, if the digital camera does not acquire the position information from the opposite device at the time of shooting, the shooting location information of the shooting data may be inaccurate.

  The present invention has been made in view of the above problems, and an object of the present invention is to store accurate position information together with captured still image or moving image data while suppressing power consumption of a camera or the like.

  The information processing system according to the present embodiment is an information processing system including an information processing terminal and a camera, and the information processing terminal includes a position acquisition unit that acquires information on a position of the information processing terminal, and the position When the position specified by the current position information acquired by the acquisition unit and the position specified by the position information notified to the camera have changed by a predetermined distance or more, the current position information is sent to the camera. A first communication unit that notifies the camera, and the camera receives a second communication unit that receives the position information from the information processing terminal, a storage unit that stores the received position information, and a stationary unit. An image capturing unit that captures an image or a moving image, and when the second communication unit detects a signal from the information processing terminal when the still image or the moving image is captured, the storage unit The stationary was filmed Or said video, in association with information of has been the position stored in the storage unit.

  According to the present embodiment, it is possible to provide an information processing system, a camera, an information processing terminal, and a program that store accurate position information together with captured still image or moving image data while suppressing power consumption of the camera or the like. It becomes possible.

[First Embodiment]
<Overall configuration and functional configuration>
The overall configuration and functional configuration of the information processing system 1 according to the present embodiment will be described with reference to FIGS. 1 and 2.

(1) Overall Configuration The information processing system 1 includes a terminal 10 and a camera 20. The terminal 10 and the camera 20 communicate via the wireless link 30.

  The wireless link 30 is, for example, WLAN (Wireless LAN), Bluetooth (registered trademark), or BLE (Bluetooth Low Energy).

  The terminal 10 has a function of acquiring information on its own position. The terminal 10 may acquire information on the latitude and longitude of its own position using, for example, GPS. In addition to the information acquired from the GPS, the terminal 10 may accurately specify its own position from the information of the connected WLAN AP (Access Point). Further, the terminal 10 may transmit information acquired from the GPS and information on the connected WLAN AP to a server on the network, and may receive information on a position calculated by the server from the information.

  The terminal 10 is, for example, a smartphone, a tablet terminal, a notebook PC, or the like. The terminal 10 only needs to be able to acquire information on its own position and to communicate with the camera 20 via the wireless link 30 by the method described above. It should be noted that the type of the terminal 10 is not particularly limited.

  The camera 20 communicates with the terminal 10 via the wireless link 30 and receives various settings for the camera 20 from the terminal 10.

  The camera 20 does not have a function of acquiring information about its own position. The camera 20 acquires information on the position of the terminal 10 from the terminal 10. The camera 20 stores information on the position in association with captured moving image or still image data (hereinafter referred to as imaging data). Information including shooting data and position information associated with the shooting data may be referred to as image information.

(2) Functional Configuration The information processing system 1 according to this embodiment includes a terminal 10 and a camera 20. The terminal 10 is an example of an information processing terminal.

  The terminal 10 includes a position acquisition unit 120 that acquires the position of the terminal 10 and a communication unit 130 that notifies the camera 20 of information on the position acquired by the position acquisition unit 120. When the position changes by a predetermined distance or more, the communication unit 130 notifies the camera 20 of information on the changed position.

  Specifically, when the position specified by the current position information acquired by the position acquisition unit 120 and the position specified by the position information notified to the camera 20 change by a predetermined distance or more, the communication unit 130 The camera 20 is notified of the current position information.

  The communication unit 130 is an example of a first communication unit.

  The position information is, for example, information on latitude and longitude. The location information may include a place name in addition to the latitude and longitude information.

  The terminal 10 includes an input / output unit 140 and a control unit 150. The input / output unit 140 receives various settings from the user for the terminal 10. The input / output unit 140 outputs content related to the terminal 10. The input / output unit 140 receives a setting related to “predetermined distance” from the user. In the “predetermined distance”, for example, a distance such as 10 m or 50 m is set. When the “predetermined distance” is short, the terminal 10 can notify the camera 20 of accurate position information. However, in this case, the frequency at which the terminal 10 notifies the camera 20 of the position information increases, and the consumption of the battery 274 of the camera 20 increases. For this reason, the “predetermined distance” is preferably set in consideration of both the accuracy of the position and the consumption amount of the battery 274.

  The control unit 150 performs various controls on each function of the terminal 10.

  The camera 20 includes a communication unit 220 that receives position information from the terminal 10, a storage unit 230 that stores the received position information, and a shooting unit 240 that takes a still image or a moving image. When the communication unit 220 detects a signal from the terminal 10 when a still image or a moving image is shot, the storage unit 230 stores the shooting data and the position information stored in the storage unit 230 in association with each other. To do. Image information including shooting data and position information is stored in the storage unit 230. Here, the communication unit 220 is an example of a second communication unit.

  When the camera 20 can detect a signal from the terminal 10, the position information stored in the camera 20 is accurate. Specifically, the position of the terminal 10 is within the range of “predetermined distance” from the position specified by the position information.

  Here, “signal can be detected” means that the camera 20 can specify that the terminal 10 is the transmission source of the received signal such as WLAN or Bluetooth. For example, when WLAN is used, the camera 20 can detect a signal including the SSID of the WLAN.

  The camera 20 has an input / output unit 250. The input / output unit 250 receives various settings from the user for the camera 20. The input / output unit 250 outputs contents related to the camera 20. The input / output unit 250 outputs stored image information in response to a request from the user.

  When the communication unit 220 does not detect a signal from the terminal 10 when a still image or a moving image is shot, the storage unit 230 does not store the shooting data and the position information stored in the storage unit 230 in association with each other. . That is, the storage unit 230 stores image information that does not include position information.

  When the signal from the terminal 10 is not detected, even if the position of the terminal 10 changes by a predetermined distance or more, the camera 20 cannot receive the information on the changed position. In this case, the position information stored in the storage unit 230 may not be accurate.

  In response to the imaging unit 240 accepting an instruction for imaging, the communication unit 220 may determine whether or not a signal from the terminal 10 can be detected.

  When the communication unit 220 receives position information from the terminal 10 during moving image shooting, the storage unit 230 stores the shot moving image and the position information received during shooting in association with each other.

  Moreover, the control part 260 may estimate the movement locus | trajectory of the camera 20 during imaging | photography of a moving image from the information of one or more positions memorize | stored with the moving image.

  As a result, the stored image information includes information on the position at the start of shooting of the moving image, information on one or more positions during shooting of the moving image, and information on the position at the end of shooting of the moving image. Using the information on these positions, the camera 20 can estimate the trajectory of the movement of the camera 20 during moving image shooting. The estimation of the trajectory may be executed by an information processing apparatus such as a PC that has acquired image information.

  Here, the control unit 260 is an example of an estimation unit.

  Note that the terminal 10 may notify the position information to devices other than the camera 20 in the same procedure as in the case of the camera 20.

  The communication unit 130 of the terminal 10 transmits signals to the camera 20 and devices other than the camera 20 so that the camera 20 and devices other than the camera 20 detect signals from the terminal 10. Such a signal includes the identifier of the terminal 10. For example, when such a signal is transmitted using WLAN, the SSID of the terminal 10 is included.

(3) Image information stored in the storage unit The image information stored in the storage unit 230 will be described with reference to FIG. FIG. 2 is an example of image information stored in the storage unit 230.

  When the communication unit 220 can detect a signal from the terminal 10 at the time of shooting, the shooting data is stored together with position information. Further, the shooting data may be stored together with the shooting time.

  The image information with the identification number “1” includes shooting data “still image #A”, a shooting location (latitude: AAA.BBB, longitude: CCC.DDD) and shooting time (2015/07). / 02, 15:03:01). Here, the latest position information received by the camera 20 from the terminal 10 is set as the position information at the time of shooting.

  The image information with the identification number “2” includes shooting data “moving image #A”, information on a plurality of positions related to the shooting data, and shooting times corresponding to the information on the plurality of positions. Specifically, the image information with the identification number “2” includes, in addition to the shooting data, position information and shooting time at each of the start point, the intermediate point # 1, the intermediate point #n, and the end point at which the shooting is started. .

  Each time position information is notified from the terminal 10 when shooting a moving image, the storage unit 230 stores the position. Such a position may be referred to as a midpoint position. The image information with the identification number “2” indicates that position information has been notified n times (n is a natural number) during shooting.

  The storage unit 230 stores the information on the position of the intermediate point and the time when the notification is received. Note that the shooting start time is stored as the shooting start time. As the shooting time of the end point, the time when shooting is finished is stored.

  By recording the position of the intermediate point and the time at which the notification is received, the control unit 260 can estimate the moving path, moving speed, and the like of the camera 20 during moving image shooting.

  When the communication unit 220 cannot detect a signal from the terminal 10, the storage unit 230 does not store the position information together with the shooting data. This is because the position information stored in the storage unit 230 may be inaccurate.

  The image information with the identification number “3” indicates a case where position information is not stored. In this case, shooting data “still image #B” and shooting time (2015/07/04, 12:15:20) are stored.

  The image information may include shooting data size, file format, and the like in addition to shooting data, position information, and shooting date and time.

  In step S501, the input / output unit 140 of the terminal 10 receives a request for starting an application that cooperates with the camera 20 from the user. In response to the input, the control unit 150 of the terminal 10 activates the application.

  In step S <b> 502, the position acquisition unit 120 of the terminal 10 acquires information on the position of the terminal 10. For example, the position acquisition unit 120 receives a signal from a GPS satellite and measures the position of the terminal 10 from the signal. As a result of the measurement, the position acquisition unit 120 acquires position information. The position acquisition unit 120 may specify the position of the terminal 10 using the information of the WLAN AP in addition to the signal from the GPS satellite.

  Further, the position acquisition unit 120 may transmit the signal received from the GPS satellite and the WLAN AP information to the server, and acquire the information on the position of the terminal 10 specified by the server from the server.

  In step S <b> 503, the communication unit 130 of the terminal 10 transmits a connection request to the camera 20.

  In step S <b> 504, the user turns on the power of the camera 20 so that the communication unit 220 of the camera 20 can receive a signal from the terminal 10.

  When a connection is established between the terminal 10 and the camera 20, the communication unit 130 of the terminal 10 transmits information on the position of the terminal 10 to the camera 20 in step S506. Note that the position acquisition unit 120 of the terminal 10 may acquire the position of the terminal 10 again before transmitting the position information to the camera 20 (step S505). By executing such processing, the terminal 10 can notify the camera 20 of the latest information on the position of the terminal 10.

  In step S510, the communication unit 220 of the camera 20 receives the current position information.

  In step S511, the storage unit 230 of the camera 20 stores information on the current position.

  With reference to FIG. 6, an operation procedure when the camera 20 performs shooting of a still image or a moving image will be described.

  In step S601, the input / output unit 250 of the camera 20 accepts a shooting instruction from the user.

  In step S <b> 602, the communication unit 220 of the camera 20 confirms the communication state with the terminal 10. Here, the confirmation of the communication state with the terminal 10 means that the camera 20 receives a wireless signal such as WLAN or Bluetooth and determines whether or not the signal transmission source can be confirmed with the terminal 10. “Checking the communication state with the terminal 10” may be expressed as “determining whether the signal of the terminal 10 can be detected”.

  In step S603, the communication unit 220 of the camera 20 determines whether the signal from the terminal 10 can be detected. If the signal from the terminal 10 can be detected (YES in step S603), the process proceeds to step S604. On the other hand, if the signal from the terminal 10 cannot be detected (NO in step S603), the process proceeds to step S606.

  In step S604, the photographing unit 240 of the camera 20 confirms the photographing mode.

  In step S605, the shooting unit 240 of the camera 20 determines whether to perform shooting with a moving image or shooting with a still image.

  When shooting with a still image (step S605: shooting a still image), the process proceeds to step S607. When shooting with moving images (step S605: shooting moving images), the process proceeds to step S608.

  When the process proceeds to step S606, the imaging unit 240 captures a still image or a moving image. Shooting data generated as a result of shooting is stored in the storage unit 230 of the camera 20, but position information is not stored in association with shooting data.

  In step S607, the imaging unit 240 of the camera 20 captures a still image. The storage unit 230 of the camera 20 stores still image shooting data together with the position information stored in the storage unit 230.

  In step S608, the imaging unit 240 of the camera 20 captures a moving image. When the video shooting is finished, the communication unit 220 of the camera 20 confirms the communication state with the terminal 10.

  If the communication unit 220 of the camera 20 can detect the signal from the terminal 10 in step S609 (YES in step S609), the process proceeds to step S610. On the other hand, when the communication unit 220 of the camera 20 cannot detect the signal of the terminal 10 (NO in step S609), the process proceeds to step S611.

  In step S610, the storage unit 230 of the camera 20 stores the moving image shooting data and the position information in the storage unit 230 in association with each other.

  When the position information at the start of shooting is different from the position information at the end of shooting, the storage unit 230 of the camera 20 stores the time at which shooting starts, the time at which shooting ends, and each time.

  When the communication unit 220 of the camera 20 receives the position information from the terminal 10 during the shooting of the moving image, the storage unit 230 of the camera 20 includes the position information in addition to the position information of the shooting start time and the end time. Is stored in association with the time of receiving the information.

  In step S611, the storage unit 230 of the camera 20 stores moving image shooting data that does not include position information.

  When the exact position of the camera 20 cannot be specified, it is possible to prevent the moving image shooting data from being stored together with the position information.

  It should be noted that the storage unit 230 of the camera 20 may store the position information other than the position information at the time when shooting is finished and moving image shooting data in association with each other. In this case, the storage unit 230 stores moving image shooting data, position information at the start of shooting, and position information received from the terminal 10 during shooting of the moving image. As in step S610, the position information is stored together with the time.
