Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the configurations described in the following embodiments are merely examples, and the scope of the present invention is not limited by the configurations described in the embodiments.

FIG. 1 is a configuration diagram of an imaging system 1 according to an embodiment of the present invention. The imaging system 1 of FIG. 1 includes a digital camera 100 and a wearable camera 200. In FIG. 1, the wearable camera 200 is mounted on the digital camera 100. The digital camera 100 can capture a still image or a moving image of a subject based on a user's operation by itself. In this case, the wearable camera 200 can capture a still image or a moving image of a subject based on the user's operation by itself. The digital camera 100 and the wearable camera 200 are image pickup devices. The plurality of imaging devices combined in the imaging system 1 may be other combinations, or three or more imaging devices may be combined. Each image pickup device to be combined is selected from, for example, a mobile phone, a surveillance camera, an in-vehicle camera, and a game machine having an image pickup function, a tablet terminal, a personal computer, and a glasses-type or clock-type information terminal. It's fine.

Then, in the imaging system 1 of FIG. 1, the user operates, for example, the digital camera 100, the digital camera 100 captures a still image, and the wearable camera 200 captures a moving image based on an instruction request of the digital camera 100. Can be considered. Further, the moving image data is transmitted from the wearable camera 200 to the digital camera 100, and the moving image data received by the digital camera 100 and the still image data are combined and recorded. By recording the still image and the moving image in association with each other in this way, it is possible to record the change in the facial expression of the subject and the sound at the imaging site, which cannot be obtained by the still image of the subject, together with the still image. When reproducing the imaging, the atmosphere and the sense of presence of the place can be reproduced, and the memory at the time of imaging can be recalled more clearly. However, in such an imaging system 1, the processing load of the digital camera 100 used as the first imaging device for still images becomes high. The digital camera 100 captures a still image at least based on a user operation, instructs the wearable camera 200 as a second imaging device for moving images to start capturing moving images, and receives and records moving image data from the wearable camera 200. There is a need to. Further, since the moving image data is transmitted from the wearable camera 200 to the digital camera 100, the processing load of the data communication becomes large and the data communication time becomes long. As a result, it takes time from the start of imaging to the completion of recording the combined data of one moving image and the still image. The digital camera 100 has a high possibility of missing a shutter chance for capturing a still image. As described above, the imaging system 1 is required to suppress the occurrence of these situations so that the still image and the moving image can be recorded in association with each other. In the imaging system 1, the digital camera 100 used as the first imaging device for still images is a digital single-lens reflex camera, a mirrorless camera, or the like having a still image photographing function having higher performance than the wearable camera 200, and is the first for moving images. (Ii) The wearable camera 200 used as the imaging device may be a mobile terminal, a smartphone, a small camera, or the like having a photographing function. In this implementation failure, since the wearable camera 200 automatically shoots a moving image in response to an instruction from the digital camera 100, the digital camera 100 is not aware of moving image shooting and has a high-performance still image shooting function. It is possible to shoot a moving image with the wearable camera 200 while shooting a still image without lowering it.

The first coding unit 104 encodes the imaged data processed by the first image processing unit 103 by a still image data coding method or a moving image data coding method. As a result, still image data about the still image captured by the digital camera 100 or moving image data about the moving image is generated. The first communication unit 106 is the first communication means, and has, for example, a dedicated circuit or a functional block that executes a process related to wireless communication. The first communication unit 106 executes data communication with an external device such as a wearable camera 200. The first communication unit 106 executes the connection process according to the communication standard used for communication with the wearable camera 200, for example, and establishes the communication with the wearable camera 200.

The first operation unit 110 has, for example, an operation button, a dial, and a touch panel. The first operation unit 110 detects a user operation on the digital camera 100. The first RAM 107 is, for example, a semiconductor memory. In the first RAM 107, for example, the current imaging setting data and the expanded program are recorded. The first memory 108 is, for example, a non-volatile semiconductor memory or a magnetic memory. Still image data and moving image data captured by the digital camera 100 and a program executed by the first CPU 105 are recorded in the first memory 108. The first CPU 105 is, for example, a CPU or an MPU. The first CPU 105 reads the program stored in the first memory 108, expands it into the first RAM 107, and executes the program. As a result, the digital camera 100 is realized with a first control unit as a first control means for controlling the entire digital camera 100.

FIG. 3 is a functional configuration diagram of the wearable camera 200 of FIG. The wearable camera 200 of FIG. 3 includes a second lens 201, a second imaging unit 202, a second image processing unit 203, a second coding unit 204, a second CPU 205, and a second system bus 211 to which these are connected.

Will be done. Each of these parts may have the same function as the component of the same name of the digital camera 100 of FIG. 2, and the description thereof will be omitted. However, in the wearable camera 200, the second operation unit 210 has an operation button or the like, and the second display unit 209 is small. Therefore, when operating the imaging system 1 of FIG. 1, the user should use the first operation unit 110 of the digital camera 100, which has better operability than the second operation unit 210 of the wearable camera 200. desirable.

The same applies to each functional block shown in the wearable camera 200 of FIG.

FIG. 4 is a sequence chart showing an example of the moving image association processing in the imaging system 1 of FIG. FIG. 4 illustrates a user, a digital camera 100, and a wearable camera 200. In FIG. 4, the process or time flows from top to bottom. In FIG. 4, it is assumed that the wearable camera 200 constantly records a moving image, and the captured moving image data is recorded in the second memory 208. FIG. 5 is an explanatory diagram of an example of the moving image generation request message 500 of FIG. FIG. 6 is an explanatory diagram of an example of the moving image deletion request message 600 of FIG. FIG. 7 is an explanatory diagram of an example of the moving image reproduction request message 700 of FIG. These messages are transmitted by wireless communication from the first communication unit 106 of the digital camera 100 to the second communication unit 206 of the wearable camera 200.

Based on the user operation in step S401 of FIG. 4, the first CPU 105 of the digital camera 100 activates the digital camera 100. For example, when a button operation by the user is detected in the first operation unit 110, the first CPU 105 initializes and activates each block of the digital camera 100. Based on the user operation in step S402, the first CPU 105 sets the operation mode of the digital camera 100 to the moving image additional recording mode. Here, the moving image additional recording mode is a mode in which moving images are captured together in the still image capturing of the digital camera 100, and these still images and the moving image are recorded in association with each other. The first CPU 105 of the digital camera 100 executes a setting process for capturing a moving image together with a still image for the moving image additional recording mode. In step S403, which is the setting process of the moving image additional recording mode, the first CPU 105 activates the access point by the first communication unit 106 in order to establish wireless communication with the second communication unit 206 of the wearable camera 200. In step S404, the second CPU 205 of the wearable camera 200 wirelessly communicates the SSID and password establishment request message held by the pre-establishment from the second communication unit 206 to the first communication unit 106 of the digital camera 100. In step S405, the first CPU 105 compares the SSID and password received by the first communication unit 106 with the information of the access point activated in step S403. Then, when these match, the first CPU 105 wirelessly communicates the permission message of the establishment request from the first communication unit 106 to the second communication unit 206 of the wearable camera 200. As a result, a wireless communication connection between the digital camera 100 and the wearable camera 200 is established. In step S406, the first CPU 105 wirelessly communicates the acquisition request message of the moving image resolution from the first communication unit 106 to the second communication unit 206 of the wearable camera 200. In step S407, the second CPU 205 wirelessly communicates the resolution of the moving image being captured from the second communication unit 206 to the first communication unit 106 of the digital camera 100. As a result, the setting process of the moving image additional recording mode is completed, and the digital camera 100 is in a state where imaging in the moving image additional recording mode is possible.

Based on the user operation in step S408, the first CPU 105 sets the imaging conditions for the still image by the digital camera 100. The first CPU 105 sets camera parameters such as shutter speed, exposure, ISO sensitivity, and flash ON / OFF for capturing a still image. When the user's camera operation is detected by the first operation unit 110, the first CPU 105 changes the setting of each functional block to reflect the setting by the camera parameter (imaging condition) in the operation setting of each functional block. Based on, for example, the shutter button imaging operation by the user in step S409, the first CPU 105 executes the still image imaging process for the moving image additional recording mode based on the current settings. The first imaging unit 102 generates imaging data based on the settings of the camera parameters. The captured data is recorded in the first RAM 107. In step S410, the first CPU 105 wirelessly communicates, for example, the moving image generation request message 500 of FIG. 5 from the first communication unit 106 to the second communication unit 206 of the wearable camera 200. When the digital camera 100 and the wearable camera 200 are capturing the same subject or capturing a common direction, the first CPU 105 sends the moving image generation request message 500 of FIG. 5 from the first communication unit 106. Wireless communication may be performed. The second communication unit 206 of the wearable camera 200 receives the moving image generation request message 500. Step S410 is a request receiving step.

The moving image generation request message 500 in FIG. 5 is XML format data for an imaging request. The moving image generation request message 500 has a moving image generation request tag 501, an imaging time tag 502, a pre-imaging period tag 503, and a post-imaging period tag 504. The video generation request tag 501 indicates that the message requests video generation. The imaging time tag 502 indicates the imaging time, which is the imaging timing of the still image. The imaging time of the still image may be in a format according to, for example, ISO8601. The pre-imaging period tag 503 indicates the imaging period of the moving image before that, with reference to the imaging time of the still image. The post-imaging period tag 504 indicates the subsequent imaging period of the moving image with reference to the imaging time of the still image. The pre-imaging period tag 503 and the post-imaging period tag 504 have values indicating, for example, a period in seconds. In the example of FIG. 5, it is requested to generate a moving image for a total period of 6 seconds, which is a period of 4 seconds before that and a period of 2 seconds after that, based on the imaging time of the still image.

In step S411 of FIG. 4, the second CPU 205 of the wearable camera 200 generates imaging data of a moving image for a period specified by the moving image generation request message 500 based on receiving the moving image generation request message 500. The second CPU 205 generates imaging data of the moving image captured by the second imaging unit 202 as an imaging means for capturing the moving image. Step S411 is a generation step. The second CPU 205 reads out the moving image of the period for which the moving image acquisition is requested from the moving image data of the wearable camera 200 recorded at any time in the second memory 208, and captures the moving image of the period before and after the still image taking timing. To generate. The second CPU 205 generates moving image imaging data for a period including a timing before and after the still image imaging timing according to the still image imaging timing. The second CPU 205 generates moving image data from a predetermined time before the still image imaging timing. The second CPU 205 generates imaging data of a moving image in a period before and after the imaging timing including the imaging timing of a still image. The second CPU 205 records the captured image data of the generated moving image in the second memory 208 separately from the moving image data recorded at any time. In step S412, the first CPU 105 records the imaging data generated in step S409. The first image processing unit 103 executes image processing such as brightness correction on the image of the captured data recorded in the first RAM 107. The first coding unit 104 encodes the imaged data processed by the first image processing unit 103 by a still image data coding method. The first memory 108 records the encoded imaging data in the first memory 108. As a result, the captured still image is recorded in the first memory 108 of the digital camera 100.

In step S413, the first CPU 105 resizes (reduces) the captured data of the still image so that the resolution of the still image captured by the digital camera 100 becomes the resolution of the moving image of the wearable camera 200 acquired in step S407. In step S414, the first CPU 105 wirelessly communicates the imaged data of the still image resized as necessary from the first communication unit 106 to the second communication unit 206 of the wearable camera 200. Step S414 The second communication unit receives the captured image data of the still image. Step S414 is a still image receiving step. By resizing to reduce the size, the amount of data communication for the captured data of the still image is reduced. If the digital camera 100 detects the next still image imaging operation during the processes from step S412 to step S414, the first CPU 105 interrupts those processes before the end of the process, and the next still image is displayed. The image data generation process is executed. As described above, the first CPU 105 gives priority to the imaging process of the next still image based on the user operation over the processing of the captured still image in steps S412 to S414. As a result, the digital camera 100 does not become busy due to processing for transmission to the wearable camera 200 or the like. The operability of the digital camera 100 becomes comfortable without delay due to the process for transmitting to the wearable camera 200. In this case, after the next imaging process, the first CPU 105 restarts the processing for the captured still image in steps S412 to S414. In this case, the first CPU 105 will transmit a plurality of captured still image data after the completion of their imaging. In step S415, the second CPU 205 of the wearable camera 200 connects the still image imaging data received in step S414 to the imaging data of the moving image for a predetermined period generated in step S411 and records it in the second memory 208. .. Step S415 is a recording step. As a result, the second CPU 205 associates the captured data of the still image with the captured data of the moving image. The second CPU 205 may associate a still image with a moving image by generating a file for storing these data in a predetermined area of the second memory 208. The file of the associated imaging data includes information on the imaging time of the still image included in the moving image generation request message 500. The second CPU 205 may insert a still image at a predetermined time between the portion of the moving image before the start of still image imaging and the portion after the start of still image imaging. Further, in the digital camera 100, the first CPU 105 may capture a still image by the first imaging unit 102 as well as a moving image having an imaging timing before the still image, and transmit these in step S414. In this case, the second CPU 205 of the wearable camera 200 connects the still image and moving image imaging data received by the second communication unit 206 with the moving image imaging data of the predetermined period generated in step S411 to the second memory. It may be recorded at 208. The second CPU 205 transcodes the format of the moving image captured by the digital camera 100 into a moving image format that can be played by the wearable camera 200, and transfers the still image together with the combined moving image to the second memory 208. You may record it. By the above processing, in the second memory 208 of the wearable camera 200, the still image captured and transmitted by the digital camera 100 and the moving image of the period including before and after the imaging timing of the still image are recorded in association with each other. .. The second memory 208 is a recording means capable of recording data related to imaging.

Next, the process of deleting the imaging data associated with the still image and the moving image, which is recorded in the second memory 208 of the wearable camera 200, will be described. In step S416 of FIG. 4, the first CPU 105 displays the review image of the still image captured by the digital camera 100 on the first display unit 109. Based on the deletion operation by the user during image display in step S417, the first CPU 105 deletes the captured image data of the displayed still image from the first memory 108. In step S418, the first CPU 105 wirelessly communicates, for example, the moving image deletion request message 600 of FIG. 6 from the first communication unit 106 to the second communication unit 206 of the wearable camera 200. The first CPU 105 transmits a message including the imaging time of the deleted still image, not the imaging data of the deleted still image. The second communication unit 206 of the wearable camera 200 receives the moving image deletion request message 600. The second CPU 205 compares the imaging time included in the moving image deletion request message 600 with the imaging time included in the associated imaging data recorded in the second memory 208, and selects the associated imaging data including the same imaging time. To do. Then, the second CPU 205 deletes the selected associated imaging data from the second memory 208. As a result, the second CPU 205 can delete the imaging data of the moving image generated according to the imaging timing of the deleted still image.

The moving image deletion request message 600 of FIG. 6 is XML format data for the deletion request. The moving image deletion request message 600 has a moving image deletion request tag 601 and a still image imaging time tag 602. The video deletion request tag 601 indicates that the message requests the video deletion. The imaging time tag 602 indicates an imaging time which is an imaging timing of a still image.

Next, the reproduction process of the image pickup data associated with the still image and the moving image recorded in the second memory 208 of the wearable camera 200 will be described. Based on the playback operation by the user in step S419 of FIG. 4, the first CPU 105 starts the playback process of the moving image recorded in the second memory 208 of the wearable camera 200. In step S420, the first CPU 105 wirelessly communicates, for example, the moving image reproduction request message 700 of FIG. 7 from the first communication unit 106 to the second communication unit 206 of the wearable camera 200. In step S421, the second CPU 205 compares the imaging time included in the moving image reproduction request message 700 with the imaging time included in the associated imaging data recorded in the second memory 208, and associates the imaging time including the same imaging time. Select the imaging data. Then, the second CPU 205 reads the selected associated imaging data from the second memory 208, and streams and transmits the selected association imaging data from the second communication unit 206 to the first communication unit 106 of the digital camera 100. The first communication unit 106 receives the video data transmitted by streaming. The first CPU 105 displays the streamed moving image on the first display unit 109.

The moving image reproduction request message 700 of FIG. 7 is XML format data for the reproduction request. The moving image reproduction request message 700 has a moving image reproduction request tag 701 and a still image imaging time tag 702. The video playback request tag 701 indicates that the message requests video playback. The imaging time tag 702 indicates an imaging time which is an imaging timing of a still image.

As described above, in the present embodiment, the digital camera 100 of the imaging system 1 transmits the captured data of the captured still image to the wearable camera 200. As a result, the digital camera 100 that manages the joint imaging timing by the digital camera 100 and the wearable camera 200 only needs to capture and transmit a still image based on the user operation, and a processing load other than capturing the still image is applied. It will be reduced. As a result, the digital camera 100 operated by the user for imaging can execute the processing for capturing a still image due to its original performance. Moreover, since the still image is transmitted from the digital camera 100 to the wearable camera 200, the amount of communication data to be transmitted is reduced as compared with the case of transmitting a moving image. As a result, in the present embodiment, it is possible to shorten the time from the start of imaging to the end of recording the combined data of one moving image and the still image. On the other hand, if, for example, a digital camera 100 operated by a user for imaging captures and transmits a moving image, the processing load is concentrated on the digital camera 100 as compared with the wearable camera 200. The digital camera 100 at least captures a moving image based on a user operation, instructs the wearable camera 200 that captures a still image to start capturing a moving image, and transmits the captured moving image data. There is a need to. Moreover, in this case, since the moving image data having a large amount of data is transmitted from the digital camera 100 to the wearable camera 200, the processing load of the data communication becomes large and the processing time becomes long. As a result, it takes time from the start of imaging to the completion of recording the combined data of one moving image and the still image.

For example, in the above embodiment, the first communication unit 106 of the digital camera 100 and the second communication unit 206 of the wearable camera 200 send and receive messages and imaging data by wireless communication. In addition to this, for example, the first communication unit 106 and the second communication unit 206 may send and receive messages and imaged data by wire communication.

In the above embodiment, the data associated with the still image and the moving image is recorded in the second memory 208 and then deleted. In addition to this, for example, when the captured image data of the still image before transmission is deleted based on the user operation, the first CPU 105 of the digital camera 100 may not transmit the captured image data of the still image to the wearable camera 200. Good. In this case, the second CPU 205 of the wearable camera 200 may delete the imaging data of the moving image associated with the still image from the second memory 208, or may interrupt the generation of the imaging data of the moving image. As a result, the digital camera 100 does not have to perform unnecessary processing. The digital camera 100 is less likely to be in a busy state with a high processing load. In addition, the video data on the wearable camera side that was planned to be associated may also be deleted.
