  FIG. 1 is a diagram illustrating an example of an imaging apparatus according to an embodiment of the present invention.

  The imaging devices 11-1 to 11-4 are connected to each other via a network 12 such as a wired or wireless LAN (Local Area Network) and perform mutual authentication in advance. For example, when the imaging devices 11-1 to 11-4 are digital video cameras, digital still cameras, or the like, the network 12 is an ad hoc network in a wireless LAN. Further, for example, the network 12 may be a wireless LAN that operates in an infrastructure mode using an access point. Further, the network 12 may be the Internet.

The network I / F 37 of the imaging device 11-2 is transmitted to the imaging device 11-1 via the network 12, and the processing in the imaging device 11-2 ends.

  In step S303, the reception control unit 71 of the imaging apparatus 11-1 notifies the network of the imaging apparatus 11-1 that the recording of the moving image transmitted from the imaging apparatus 11-2 via the network 12 has been completed. I / F 37 is made to receive. The reception control unit 71 of the imaging device 11-1 supplies the received notification to the display control unit 52 of the imaging device 11-1.

  In step S304, based on the notification supplied from the reception control unit 71 of the imaging device 11-1, the display control unit 52 of the imaging device 11-1 displays the window of the user B on the display unit 34 of the imaging device 11-1. The displayed message “Recording a moving image!” Is deleted, and the processing in the imaging device 11-1 ends.

  In this way, the imaging device 11-2 can create and record moving image data from the stream received from the imaging device 11-1.

  Here, for example, when the received stream from the imaging device 11-1 is “thumbnail video”, the image quality and sound quality of the recorded moving image are equal to or less than “thumbnail video”. End up.

  Next, recording processing of moving image data of a higher quality moving image will be described.

  In step S341, the reception control unit 71 of the imaging apparatus 11-1 sends a request for starting recording of a moving image transmitted from the imaging apparatus 11-2 via the network 12 to the network I / O of the imaging apparatus 11-1. F37 is received. The reception control unit 71 of the imaging device 11-1 supplies a request to start recording of the received moving image to the recording control unit 55 of the imaging device 11-1.

  In step S342, the recording control unit 55 of the imaging device 11-1 determines whether or not the video imaged by the imaging device 11-1 is recorded.

  If it is determined in step S342 that the captured video is not recorded, the process proceeds to step S343.

  In step S343, the recording control unit 55 of the imaging device 11-1 acquires a request for starting recording of a moving image, and at the same time, the video imaged by the imaging unit 31 of the imaging device 11-1, that is, moving image data. That is, the recording unit 35 of the imaging device 11-1 starts recording the moving image data.

  In step S344, the display control unit 52 of the imaging device 11-1 starts user B of the display unit 34 of the imaging device 11-1 in response to the start of recording of moving image data in the recording control unit 71 of the imaging device 11-1. Display the message “Recording video!” In the window.

  The moving image recording process in the imaging device 11-1 is continued until a recording end request is received from the imaging device 11-2.

  In step S363, when the “moving image” recording button of the window 92 displayed on the display unit 34 of the imaging device 11-2 is pressed again, the operation input unit 33 of the imaging device 11-2 displays the moving image. Enter instructions to end recording. The input receiving unit 53 of the imaging device 11-2 receives an instruction to end recording of a moving image input by a user operation. More specifically, the input reception unit 53 of the imaging device 11-2 is based on a signal indicating an instruction to end recording of a moving image acquired from the operation input unit 33 of the imaging device 11-2. 1 is supplied to the communication control unit 51 of the imaging apparatus 11-2.

  In step S364, the transmission control unit 72 of the imaging device 11-2 sends a moving image recording end request to the imaging device 11-1 based on information indicating a moving image recording end request to the imaging device 11-1. -2 is transmitted to the imaging apparatus 11-1 via the network 12.

  In step S345, the reception control unit 71 of the imaging device 11-1 sends a request to end the recording of the moving image transmitted from the imaging device 11-2 via the network 12 to the network I / O of the imaging device 11-1. F37 is received. The reception control unit 71 of the imaging device 11-1 supplies a request to end recording of the received moving image to the recording control unit 55 of the imaging device 11-1.

  In step S346, the recording control unit 55 of the imaging device 11-1 causes the recording unit 35 of the imaging device 11-1 to finish recording the moving image data based on a request to end recording of the moving image. The recording control unit 55 of the imaging device 11-1 supplies the created moving image data to the communication control unit 51 of the imaging device 11-1. After step S346, the process proceeds to step S352.

  On the other hand, when it is determined in step S342 that the captured video is recorded, the process proceeds to step S347.

  In step S347, the time recording unit 56 of the imaging device 11-1 records a recording start time that is a time when the network I / F 37 of the imaging device 11-1 receives a request to start recording a moving image.

  In step S348, the display control unit 52 of the imaging device 11-1 receives the request for starting the recording of the moving image of the network I / F 37 of the imaging device 11-1, and the display unit 34 of the imaging device 11-1. A message “Recording a moving image!” Is displayed in the window of user B.

  In step S349, the reception control unit 71 of the imaging device 11-1 issues a request to end the recording of the moving image transmitted via the network 12 from the imaging device 11-2 that executes step S364 described above. The data is received by the network I / F 37 of 11-1.

  In step S350, the time recording unit 56 of the imaging device 11-1 records a recording end time that is a time when the network I / F 37 of the imaging device 11-1 receives a request for the end of recording of a moving image.

  In step S351, the recording control unit 55 of the imaging device 11-1 records the recording unit of the imaging device 11-1 based on the recording start time and the recording end time recorded in the time recording unit 56 of the imaging device 11-1. The moving image data is created by extracting the moving image data from the recording start time to the recording end time from the video recorded in 35. The recording control unit 55 of the imaging device 11-1 supplies the created moving image data to the communication control unit 51 of the imaging device 11-1.

  In step S352, the transmission control unit 72 of the imaging device 11-1 acquires the moving image data created by recording in steps S343 to S346 or the moving image data created by extracting in step S351. The network I / F 37 of the imaging device 11-1 is transmitted to the imaging device 11-2 via the network 12.

  In step S365, the reception control unit 71 of the imaging device 11-2 causes the network I / F 37 to receive the moving image data transmitted from the imaging device 11-1 via the network 12. The reception control unit 71 of the imaging device 11-2 supplies the received moving image data to the recording control unit 55 of the imaging device 11-2.

  In step S366, the recording control unit 55 of the imaging device 11-2 causes the recording unit 35 to record the supplied moving image data.

  In step S367, the display control unit 52 of the imaging device 11-2 generates display data for displaying a representative image that is a still image representing the moving image data, based on the recorded moving image data, and performs imaging. It supplies to the display part 34 of the apparatus 11-2. The display unit 34 of the imaging device 11-2 displays a representative image of the moving image data based on the supplied display data, and the processing in the imaging device 11-2 ends. The representative image of the moving image data is displayed on, for example, the still image display unit 95 of the display unit 34 of the imaging device 11-2. The still image display unit 55 of the display unit 34 of the imaging device 11-2 may display not only the representative image of the moving image data but also the moving image itself.

  On the other hand, in step S352, after the imaging device 11-1 transmits the moving image data to the imaging device 11-2, the processing in the imaging device 11-1 proceeds to step S353.

  In step S353, the display control unit 52 of the imaging device 11-1 is displayed in the window of the user B of the display unit 34 of the imaging device 11-1 in response to transmission of moving image data to the imaging device 11-2. The message “Recording video!” Is deleted, and the process ends.

  In this manner, the imaging device 11-2 transmits a moving image recording request to the imaging device 11-1 that transmits the stream, thereby moving the moving image from the imaging device 11-1 in response to the recording request. Image data can be received and recorded.

  In addition, in the case of the processing example shown in the flowchart of FIG. 11, compared to the case of the processing example shown in the flowchart of FIG. Although some delay occurs until the start or end, moving image data with higher image quality and higher sound quality can be recorded.

  As described above, the imaging apparatus 11 can record moving image data obtained from a received stream.

  The example of the moving image recording process in FIG. 10 and the example of the moving image recording process in FIG. 11 are selected by an input indicating mode selection from the operation input unit 33, for example. May be. More specifically, for example, a button indicating each mode is provided for selection, or a single button is provided for long selection so that the mode is selected. In addition, each mode may be automatically selected according to a network bandwidth to which a plurality of imaging devices 11 are connected.

  Further, in the above description, when the imaging apparatus 11-2 records audio data or moving image data, when the recording apparatus 11-1 transmits a recording start request or a recording end request to the imaging apparatus 11-1, In step S262 and S264 of the flowchart of FIG. 9 and steps S362 and S364 of the flowchart of FIG. 11, time information may be included in the request to start recording and the request to end recording.

  The time information is information for designating the start time of recording based on the requested time, or designating the end time of recording based on the requested time. More specifically, for example, the time information is a recording start request or recording end time for how long before the time when the imaging apparatus 11-1 received the recording start request or the recording end request. Information indicating whether the request is made.

  FIG. 12 illustrates a process of transmitting a recording start request and a recording end request including time information in the imaging apparatus 11-2 when the content type for the stream requesting recording is a moving image or audio. It is a flowchart which shows the example of. For example, the time information is input to the time information adding unit 57 by being input from a button (not shown) as the operation input unit 33 which is a touch panel provided to overlap the display unit 34 of the imaging device 11-2. Supplied.

  In step S401, the time information adding unit 57 of the imaging device 11-2 requests to start recording of audio or moving images for the stream from the imaging device 11-1 supplied to the communication control unit 51 of the imaging device 11-2. Is added to the information indicating the time information, which is information indicating how long the recording apparatus 11-1 has received the recording start request from the time when the imaging apparatus 11-1 received the recording start request.

  In step S402, the transmission control unit 72 of the imaging device 11-2 records audio or moving images including time information based on information indicating a request to start recording of audio or moving images to the imaging device 11-1. A recording start request, which is a request for starting, is transmitted to the imaging apparatus 11-1 via the network 12 to the network I / F 37 of the imaging apparatus 11-2.

  In step S403, the time information adding unit 57 of the imaging device 11-2 requests to end recording of audio or moving images for the stream from the imaging device 11-1 supplied to the communication control unit 51 of the imaging device 11-2. Is added to the information indicating the time information, which is information indicating how long the recording apparatus 11-1 has received the recording end request from the time when the imaging apparatus 11-1 received the recording start request.

  In step S <b> 404, the transmission control unit 72 of the imaging device 11-2 records voice or moving image including time information based on information indicating a request to end recording of the voice or moving image to the imaging device 11-1. A recording end request, which is an end request, is transmitted to the image capturing apparatus 11-1 via the network 12 to the network I / F 37 of the image capturing apparatus 11-2, and the process ends.

  In this way, the imaging apparatus 11-2 represents time information indicating how long the recording apparatus 11-1 is a recording start or end request from the time when the imaging apparatus 11-1 receives the recording start or end request. A recording start request or a recording end request including can be transmitted.

  FIG. 13 shows a process of receiving a recording start request and a recording end request including time information in the imaging apparatus 11-1 when the content type for the stream requesting recording is a moving image or audio. It is a flowchart which shows the example of.

  In step S421, the reception control unit 71 of the imaging device 11-1 transmits a voice or moving image recording start request including time information transmitted from the imaging device 11-2 via the network 12 to the imaging device 11-. 1 network I / F 37 to receive. The reception control unit 71 of the imaging device 11-1 supplies the recording start request for the received voice or moving image to the recording control unit 55 of the imaging device 11-1.

  In step S422, the recording control unit 55 of the imaging device 11-1 records audio data or moving image data based on the time when the recording start request is received and the time information included in the recording start request. 1 recording unit 35 is started. More specifically, the recording control unit 55 of the imaging device 11-1 records audio data or moving image data from a time that is back by the time indicated by the time information of the recording start request from the time when the recording start request is received. The recording unit 35 of the imaging device 11-1 is started. Note that if audio data or moving image data is recorded by the user A at a retroactive time, no new recording is started.

  In step S423, the reception control unit 71 of the imaging device 11-1 transmits a voice or moving image recording end request including time information transmitted from the imaging device 11-2 via the network 12 to the imaging device 11-. 1 network I / F 37 to receive. The reception control unit 71 of the imaging device 11-1 supplies the received audio or moving image recording end request to the recording control unit 55 of the imaging device 11-1.

  In step S424, the recording control unit 55 of the imaging device 11-1 records audio data or moving image data based on the time when the recording end request is received and the time information included in the recording end request. 1 to the recording unit 35. More specifically, the recording control unit 55 of the imaging device 11-1 records audio data or moving image data at a time that is back by the time indicated by the time information of the recording end request from the time when the recording end request is received. The recording unit 35 of the imaging device 11-1 is terminated. Note that if audio data or moving image data is recorded by the user A at a retroactive time, the recording is not terminated.

  In this way, the imaging apparatus 11-1 receives the time information of the recording end request from the time when the recording end request is received from the time that is earlier than the time indicated by the time information of the recording start request from the time when the recording start request is received. Audio data or moving image data can be recorded up to a time that is back by the time indicated.

  Here, hereinafter, time information is appropriately expressed as VAL. However, the time information VAL is an integer of 0 or more.

  That is, the recording start request or the recording end request including the time information VAL which is 0 is a recording start request or a recording end request at the time when the request is transmitted. If the current time is time 50 and the request is transmitted at time 50, the recording start request or the recording end request including time information VAL of 10 is the start of recording from time 40, or Request to end recording.

  FIG. 14 is a diagram illustrating an example of a recording process in the imaging apparatus 11-1 when time information is included in the recording start request and the recording end request from the imaging apparatus 11-2.

  FIG. 14 shows the timing of the processing of the imaging apparatus 11-1 and the recording start request and recording end request of the imaging apparatus 11-2 at times 0 to 60. The unit of time is, for example, seconds, and may be 1 / 10th of a second or milliseconds. In addition, streaming transmission from the imaging device 11-1 to the imaging device 11-2 is started at time 0, and the user of the imaging device 11-1 is between time 0 to 30 and time 40 to 60. A certain user A records the imaged image on the imaging device 11-1.

  At time 5, a recording start request is transmitted from the imaging device 11-2, and at time 25, a recording end request is transmitted from the imaging device 11-2.

  For example, if the recording start request includes the time information VAL of 0 and the recording end request includes the time information VAL of 0, the recording from the time 5 that goes back 0 seconds indicated by the time information VAL from the time 5 Is requested, and the end of recording is requested at time 25 which is back from the time 25 by 0 seconds indicated by the time information VAL.

  At time 5, the image capturing apparatus 11-1 is continuously recording video by the user A. Therefore, even when the start of recording from time 5 is requested, recording is not newly started.

  In addition, at time 25, the image capturing apparatus 11-1 is continuously recording video by the user A. Therefore, even if the end of recording at time 25 is requested, video recording does not end.

  In this case, audio from time 5 to time 25 or audio data or moving image data of a moving image is transmitted from the imaging device 11-1 to the imaging device 11-2.

  When the time information VAL of 50 is included in the recording start request and the time information VAL of 5 is included in the recording end request, the start of recording from the time −45 that is back by 50 seconds indicated by the time information VAL from the time 50 is started. The recording is requested to end at the time 20 that is requested and goes back by 5 seconds indicated by the time information VAL from the time 25.

  However, since streaming is not started at time −45, a request to start recording from time −45 is regarded as a request to start recording from time 0. At time 0, the image capturing apparatus 11-1 is started to record video by the user A. Therefore, even if the start of recording from time 0 is requested, recording according to the request is not started.

  In addition, at time 20, the image capturing apparatus 11-1 is continuously recording video by the user A, and thus does not end recording even when the end of recording at time 20 is requested.

  In this case, sound from time 0 to time 20 or sound data or moving image data of moving images is transmitted from the imaging device 11-1 to the imaging device 11-2.

  When the recording start request includes the time information VAL of 0 and the recording end request includes the time information VAL of 20, the recording starts from the time 5 that is back from the time 5 by 0 seconds indicated by the time information VAL. And the end of recording is requested at time 5 which is 20 seconds later than time 25 indicated by time information VAL.

  At time 5, the image capturing apparatus 11-1 is continuously recording video by the user A. Therefore, even when the start of recording from time 5 is requested, recording is not newly started.

  In addition, at time 5, the image capturing apparatus 11-1 is continuously recording video by the user A. Therefore, even when the end of recording at time 5 is requested, recording is not newly completed.

  In this case, since the recording start time and the recording end time are the same time and there is no audio or moving image from the recording start time to the recording end time, the imaging device 11-1 transmits audio data to the imaging device 11-2. Or, moving image data is not transmitted.

  FIG. 15 is a diagram for explaining another example of the recording process in the imaging device 11-1 when time information is included in the recording start request and the recording end request from the imaging device 11-2.

  In FIG. 15, similarly to FIG. 14, the timing of the processing of the imaging device 11-1 and the recording start request and the recording end request of the imaging device 11-2 from time 0 to 60 are shown. In FIG. 15, the unit of time is seconds. In addition, streaming transmission from the imaging device 11-1 to the imaging device 11-2 is started at time 0, and the user of the imaging device 11-1 is between time 0 to 30 and time 40 to 60. A certain user A records the imaged image on the imaging device 11-1.

  Further, at time 35, a recording start request is transmitted from the imaging device 11-2, and at time 65, a recording end request is transmitted from the imaging device 11-2.

  For example, when the time information VAL of 0 is included in the recording start request and the time information VAL of 0 is included in the recording end request, recording from the time 35 that is back from the time 35 by 0 seconds indicated by the time information VAL Is requested, and the end of recording is requested at time 65, which is back from the time 65 by 0 seconds indicated by the time information VAL.

  Between times 35 and 40, the imaging apparatus 11-1 does not execute video recording by the user A. Therefore, the imaging apparatus 11-1 newly starts recording at time 35 and continues recording until time 40.

  In addition, since the image capturing apparatus 11-1 has not been recorded by the user A during time 60 to 65, in response to a request to end recording at time 65, the image capturing apparatus 11-1 can perform from time 60 to time 65. During this time, the video is continuously recorded, and the recording ends at time 65.

  In this case, the audio from time 35 to time 65 or the audio data or moving image data of the moving image is transmitted from the imaging device 11-1 to the imaging device 11-2.

  When 50 time information VAL is included in the recording start request and 5 time information VAL is included in the recording end request, recording starts from time -15 which is back by 50 seconds indicated by time information VAL from time 35. Is requested, and the end of recording is requested at time 60, which is five seconds after time 65 indicated by time information VAL.

  However, since streaming is not started at time -15, a request to start recording from time -15 is regarded as a request to start recording from time 0. At time 0, since the image pickup apparatus 11-1 is started to record video by the user A, even if the start of recording from time 0 is requested, recording according to the request is not started.

  In addition, at time 60, the imaging apparatus 11-1 is finished recording video by the user A, and the recording ends at time 60, so the recording ends.

  In this case, audio or moving image audio data or moving image data at time 0 to 30 and time 35 to 60 is transmitted from the imaging device 11-1 to the imaging device 11-2. That is, at time 30 to 35, no video is recorded and there is no video data, so audio data or moving image data in a section obtained by excluding the section from time 30 to 35 from the section from time 0 to 60 is transmitted. Will be.

  In this way, the imaging apparatus 11-2 can transmit a request for recording retroactively or a request for recording after the end of streaming reception. For example, when the user B of the image capturing apparatus 11-2 wants to start recording 10 seconds before the video streamed from the image capturing apparatus 11-1, the recording start request time information VAL = 10. The request is fulfilled. Also, for example, when all the videos recorded by the imaging device 11-1 are desired after the end of streaming reception, the recording start request time information VAL is set to a sufficiently large value, and the recording end request time information VAL = 0. The request is fulfilled.

  FIG. 16 is another example of display on the display unit 34 of the imaging device 11-2. Above the “Still Image”, “Audio”, and “Movie” buttons in the window 91 are “Like”, “What?”, “Yeah”, and “Wai” for inputting messages. There are provided a message input button and a handwritten panel in which, for example, “Look here” is written.

  When the user B presses the input button of the message “Like”, “What?”, “Yata” or “Wai” with a finger or a pen, the touch panel provided on the display unit 34 is overlaid. A signal corresponding to the input button of the pressed message is supplied to the control unit 36 from a certain operation input unit 33. The control unit 36 transmits a message corresponding to the pressed input button to any one or all of the imaging device 11-1, the imaging device 11-3, and the imaging device 11-4 via the network 12.
