Summary of the Invention

Problems to be Solved by the Invention

[0004] Normally, for the evaluation of the geological condition of the tunnel face and the determination of the construction method and support pattern, on-site attendance by both the orderer and the contractor of the construction is required. However, it is difficult to adjust to the ever-changing construction situation according to the on-site attendance time. In addition, there has been a concern that the risk of labor accidents increases when people approach the face.

[0005]

[0006] Therefore, as shown in Patent Document 1, it is conceivable to image the face and remotely evaluate the geological condition of the face using the image obtained by the imaging. For example, it is conceivable to image the face and transmit the moving image obtained by the imaging in real time to remotely evaluate the geological condition of the face. However, in places where tunnel construction is carried out, such as mountainous areas, the communication environment is often poor. Therefore, it is difficult to directly transmit a high-resolution moving image that can evaluate the geological condition of the face to a remote location.The present invention has been made in view of the above, and an object thereof is to provide a terminal capable of appropriately sharing an image obtained by imaging with another terminal.

Means for Solving the Problems

[0007] In order to achieve the above object, a terminal according to the present invention includes: an acquisition unit that acquires a low-resolution moving image and a high-resolution still image obtained by imaging the same imaging target; a moving image processing unit that displays the moving image acquired by the acquisition unit on the own terminal and transmits it to another terminal for display; and a still image processing unit that displays the still image acquired by the acquisition unit on the own terminal simultaneously with the moving image, and inputs a trigger according to the display to transmit the still image to another terminal for simultaneous display with the moving image.

[0008] In the terminal according to the present invention, a low-resolution moving image is displayed and transmitted to another terminal for display. Also, a high-resolution still image is displayed simultaneously with the moving image. When a trigger corresponding to the display is input, the still image is transmitted to another terminal for display. By these, both the low-resolution moving image and the high-resolution still image are simultaneously shared between the terminal according to the present invention and another terminal. For example, in the evaluation of the geological state of the face of a tunnel, the overall geological state of the face can be grasped by the low-resolution moving image, and the details of the geological state of the face can be grasped by the high-resolution still image.

[0009] In addition, since the images transmitted from the terminal according to the present invention to another terminal are a low-resolution moving image and a high-resolution still image according to the input of the trigger, they can be appropriately transmitted even in a poor communication environment. Also, in the terminal according to the present invention, appropriate still images can be transmitted. Thus, according to the terminal of the present invention, images such as the face of a tunnel can be appropriately shared with another terminal.

[0010] The still image processing means may receive a designation of a range on the still image and enlarge and display a portion of the still image within the designated range. According to this configuration, a more appropriate trigger according to the display can be set, and a more appropriate still image can be transmitted.

[0011] The still image processing means may display the still image larger than the moving image on the own terminal. According to this configuration, the still image can be made easier to confirm by the display of the terminal according to the present invention.

[0012] The still image processing means may receive, as an input of a trigger according to the display, a user operation to transmit the still image to another terminal. According to this configuration, the user can view the displayed still image and transmit it to another terminal.

Advantages of the Invention

[0013] According to the present invention, an image obtained by imaging can be appropriately shared with another terminal.

Modes for Carrying Out the Invention

[0015] Hereinafter, embodiments of the terminal according to the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same reference numerals are assigned to the same elements, and redundant descriptions are omitted.

[0016] FIG. 1 shows an imaging terminal 10 which is a terminal according to the present embodiment. The imaging terminal 10 is a terminal that shares images with another terminal. Another terminal according to the present embodiment is a remote terminal 20. The imaging terminal 10 performs imaging (photographing) on an imaging target (subject) and shares the image obtained by the imaging with the remote terminal 20. The imaging terminal 10 is used by a user who is an imaging person at a position where imaging of the imaging target is possible. The remote terminal 20 is used by another user at a remote location away from the imaging target.

[0017] By sharing an image between the imaging terminal 10 and the remote terminal 20, the user of the remote terminal 20 can confirm the imaging target remotely without going to the location of the imaging target. The sharing of the image may be performed in real time. The imaging target is, for example, the face of a tunnel during tunnel construction. In this case, the user of the imaging terminal 10 is, for example, an order recipient who has received an order for tunnel construction. The user of the remote terminal 20 is, for example, an order placer and a consultant who have placed an order for tunnel construction.

[0018] The above sharing of the image is used for the evaluation of the geological condition of the face of the tunnel at a remote location and the determination of the construction method and the support pattern based on the evaluation. Thereby, when evaluating the geological condition of the face of the above tunnel, etc., the number of people approaching the face of the tunnel can be reduced, and the risk of occurrence of industrial accidents can be suppressed. In addition, since the person who performs confirmation, etc. at a remote location does not need to attend the site, it is easy to adjust the time.

[0019] The images shared between the imaging terminal 10 and the remote terminal 20 are a low-resolution moving image and a high-resolution still image. With the low-resolution moving image, the situation of the imaging target including movement can be confirmed. With the high-resolution still image, the details of the imaging target can be confirmed. Note that the above low resolution and high resolution may be relative. That is, it is only necessary that the resolution of the moving image is lower than the resolution of the still image. In this way, a moving image and a still image may be shared simultaneously between the imaging terminal 10 and the remote terminal 20.

[0020] In addition, the imaging terminal 10 and the remote terminal 20 may be able to communicate with each other by voice through a conventional method such as a voice call. Accordingly, the user of the imaging terminal 10 and the user of the remote terminal 20 can communicate by voice regarding the evaluation of the geological state of the face of the tunnel and the like.

[0021] Note that the imaging target may be other than the face of the tunnel, and the image sharing may be performed for purposes other than the above according to the imaging target. Further, the remote terminal 20 (another terminal) that shares an image with the imaging terminal 10 may be used outside a remote location.

[0022] The imaging terminal 10 is, for example, a terminal such as a tablet terminal (including a tablet PC (personal computer)), a smartphone, or a PC. Specifically, the imaging terminal 10 is a computer including hardware such as a CPU (Central Processing Unit) and a memory. The imaging terminal 10 is provided with an imaging device such as a camera. The imaging device included in the imaging terminal 10 can obtain (generate) both the above-mentioned moving image and still image by imaging. The imaging device may be externally attached to the imaging terminal 10. Note that the imaging for obtaining the moving image and the still image does not necessarily have to be performed simultaneously.

[0023] The imaging terminal 10 is provided with a display device such as a display. The imaging terminal 10 has a communication function and can transmit and receive information to and from the remote terminal 20 and other devices via the network N. The communication function of the imaging terminal 10 may be a wireless communication function such as a wireless LAN (local area network) communication function or a mobile communication function. Each function of the imaging terminal 10 described later is exhibited by these components operating according to a program or the like.

[0024] The remote terminal 20 is a terminal such as a tablet terminal, a smartphone, or a PC. Specifically, the remote terminal 20 is a computer including hardware such as a CPU and a memory. The remote terminal 20 is provided with a display device such as a display. The remote terminal 20 has a communication function and can transmit and receive information to and from the imaging terminal 10 and other devices via the network N. Note that, in the functions according to the present embodiment, since imaging by the remote terminal 20 is not necessary, the remote terminal 20 does not need to be provided with an imaging device.

[0025] The network N provides a communication function to the imaging terminal 10, the remote terminal 20, and the like. The network N is, for example, a wireless LAN, a wired LAN, a mobile communication network, or the Internet, or may be composed of a plurality of these. Usually, since communication is not possible inside the tunnel where imaging is performed by the imaging terminal 10, a communication device constituting the network N may be provided inside the tunnel in order to make the imaging terminal 10 communicable inside the tunnel. The communication device provided inside the tunnel is, for example, an access point of a wireless LAN and a device that relays communication wirelessly. The network N may be provided with a device (for example, a distribution server) that relays transmission and reception of an image or the like between the imaging terminal 10 and the remote terminal 20.

[0026] Subsequently, the functions of the imaging terminal 10 according to the present embodiment will be described. As shown in FIG. 1, the imaging terminal 10 includes an acquisition unit 11, a moving image processing unit 12, and a still image processing unit 13.

[0027] The acquisition unit 11 is an acquisition means for acquiring a low-resolution moving image and a high-resolution still image obtained by imaging the same imaging target. The moving image and the still image acquired by the acquisition unit 11 are images shared between the imaging terminal 10 and the remote terminal 20.

[0028] The imaging device included in the imaging terminal 10 performs imaging to generate a low-resolution moving image and a high-resolution still image. For example, the resolution of the moving image generated by imaging can be used to check the situation of the imaging target including movement. Also, the resolution of the still image generated by imaging is higher than that of the moving image and can be used to check the details of the imaging target. Further, the imaging range of the moving image and the still image may cover the entire imaging target (for example, the entire face of the tunnel).

[0029] Imaging by the imaging device is performed according to the operation of the user of the imaging terminal 10 on the imaging device. For example, the user of the imaging terminal 10 aims the imaging device at the imaging target and performs imaging. Assuming imaging of the face of the tunnel, it is assumed to be performed from a point where the distance from the face (imaging distance) is about 10 to 20 m from the perspective of safety. The resolution of the still image may be such that even when such imaging is performed, the details of the imaging target can be checked. For example, in checking the state of the face, since it is necessary to check the crack interval of 50 mm or more, the opening of the crack, and the state of the rock surface, the resolution of the still image should be such that even when the above imaging is performed, identification of several millimeters on the face is possible.

[0030] The imaging device, for example, always performs imaging to obtain a moving image. When an operation by the user of the imaging terminal 10 is performed, the imaging for obtaining the moving image is stopped only at that moment, and imaging of a still image is performed. Thereby, the imaging device acquires two types of images, a moving image and a still image, by imaging the same imaging target.

[0031] As described above, the imaging terminal 10 communicates using a communication device provided inside the tunnel to enable communication of the imaging terminal 10. Therefore, compared to locations outside the tunnel, the network bandwidth may be narrow and the communication environment may be poor. The resolution of the moving image should be such that even in such a communication environment, the moving image can be transmitted as stream data from the imaging terminal 10 to the remote terminal 20 in real time. On the other hand, the resolution of the still image may be higher than that of the moving image. The still image can be transmitted as a data file. Therefore, even if the network bandwidth is narrow although the transmission time varies according to the network bandwidth, the high-resolution still image data can be reliably transmitted.

[0032] Note that the imaging by the imaging device does not necessarily have to be performed as described above, and any device that can generate a moving image and a still image of the same imaging target may be used. For example, two imaging devices, one for acquiring a moving image and the other for acquiring a still image, may be used. Also, the moving image and the still image may be other than those described above as long as they are a low-resolution moving image and a high-resolution still image obtained by imaging the same imaging target.

[0033] The imaging device outputs the generated moving image and still image to the acquisition unit 11 in real time. The acquisition unit 11 inputs and acquires the moving image and the still image from the imaging device. The acquisition unit 11 outputs the acquired moving image to the moving image processing unit 12 each time the moving image is acquired. The acquisition unit 11 outputs the acquired still image to the still image processing unit 13 each time the still image is acquired.

[0034] The moving image processing unit 12 is a moving image processing means for displaying the moving image acquired by the acquisition unit 11 on the own terminal 10 and transmitting it to the remote terminal 20, which is another terminal, for display.

[0035] The still image processing unit 13 is a still image processing means that displays the still image acquired by the acquisition unit 11 on the own terminal 10 simultaneously with the moving image, and inputs a trigger corresponding to the display to transmit the still image to a remote terminal 20, which is another terminal, for display simultaneously with the moving image. The still image processing unit 13 may accept the designation of a range on the still image and enlarge and display a portion of the still image within the designated range. The still image processing unit 13 may display the still image on the own terminal 10 larger than the moving image. That is, the still image processing unit 13 may make the display size of the still image on the own terminal 10 larger than the display size of the moving image. The still image processing unit 13 may accept a user operation to transmit the still image to a remote terminal 20, which is another terminal, as an input of a trigger corresponding to the display.

[0036] The images shared between the imaging terminal 10 and the remote terminal 20 are displayed on the respective terminals 10 and 20. The display of the images on the respective terminals 10 and 20 is performed, for example, as follows. FIGS. 2 and 3 show examples of the display screens 100a and 100b on the imaging terminal 10 and the display screens 200a and 200b on the remote terminal 20. The examples shown in FIGS. 2 and 3 are the display screens on the respective terminals 10 and 20 at the same timing.

[0037] The display on the imaging terminal 10 and the processes by the moving image processing unit 12 and the still image processing unit 13 are performed, for example, by a dedicated application. The display on the remote terminal 20 is performed, for example, by a web browser. Also, the processes such as the display on the respective terminals 10 and 20 may be performed by any method other than the above.

[0038] On each of the terminals 10 and 20, the moving image and the still image are displayed simultaneously. The display on each of the terminals 10 and 20 is performed, for example, in any one of two modes: a video mode and a still image mode. In the video mode, the moving image is displayed larger than the still image. In the still image mode, the still image is displayed larger than the moving image. The example shown in FIG. 2 is a display in the video mode. The example shown in FIG. 3 is a display in the still image mode.

[0039] The switching between the video mode and the still image mode is performed, for example, by an operation of the user of the imaging terminal 10 on the imaging terminal 10. The operation is, for example, an operation on the mode switching button 110 of the display screens 100a, 100b in the imaging terminal 10 (for example, a tap on the touch panel). When the mode is switched in the imaging terminal 10, information to that effect is transmitted from the imaging terminal 10 to the remote terminal 20, and the mode is also switched in the remote terminal 20. Note that the switching of the display mode may be performed by a method other than the above.

[0040] The moving image processing unit 12 and the still image processing unit 13 perform processes related to image sharing and display as follows, for example. The moving image processing unit 12 inputs a moving image from the acquisition unit 11. The moving image processing unit 12 causes the input moving image to be displayed on the display device provided in the own terminal 10. In addition, the moving image processing unit 12 transmits the input moving image to the remote terminal 20 for display on the remote terminal 20. The remote terminal 20 receives and displays the moving image transmitted from the imaging terminal 10. As shown in FIG. 2, in the video mode, the moving images 101a, 201a are displayed as the main display and are larger than the sub-display still images. As shown in FIG. 3, in the still image mode, the moving images 101b, 201b are displayed as the sub-display and are smaller than the main-display still images.

[0041] The above image sharing may be performed after an operation to share an image of the user of the imaging terminal 10 on the imaging terminal 10 is performed. The operation is, for example, an operation on the share start / stop button 111 of the display screens 100a, 100b in the imaging terminal 10 (for example, a tap on the touch panel). When the imaging terminal 10 and the remote terminal 20 are sharing an image, the imaging terminal 10 and the remote terminal 20 may display an indication that they are sharing. By this display, it is possible to easily grasp that the moving image and the still image are being shared.

[0042] When still image capturing is performed in the imaging terminal 10, the still image processing unit 13 inputs the still image from the acquisition unit 11. As described above, the still image capturing may be performed in response to an operation by the user of the imaging terminal 10. The operation is, for example, an operation on the still image capture button 112 on the display screen 100a in the video mode of the imaging terminal 10 (e.g., a tap on the touch panel).

[0043] The still image processing unit 13 causes the input still image to be displayed on the display device provided in the own terminal 10 simultaneously with the moving image displayed by the moving image processing unit 12. As shown in FIG. 2, in the video mode, the still image 102a is displayed small as a sub-display. As shown in FIG. 3, in the still image mode, the entire still image 102b is displayed small as a sub-display, and a part 103b of the still image is enlarged as a main display and displayed larger than the above sub-display.

[0044] In the still image mode, a part 103b of the still image that is enlarged and displayed as the main display is a range A specified in advance from the entire still image 102b. The range A may be specified by an operation of the user of the imaging terminal 10. That is, the still image processing unit 13 accepts the specification of a range on the still image and enlarges and displays the portion of the still image in the specified range. The position and size of the range A in the entire still image 102b may be variable. When the still image processing unit 13 inputs the still image from the acquisition unit 11 and the own terminal 10 is displaying in the video mode, it may switch to the display in the still image mode. At this time, when the remote terminal 20 is displaying in the video mode, it may continue to display in the video mode without switching to the still image mode. That is, information indicating a mode switch from the imaging terminal 10 to the remote terminal 20 may not be transmitted.

[0045] After displaying the still image, that is, in response to the display of the still image, the still image processing unit 13 inputs a trigger to transmit the still image to the remote terminal 20. For example, the still image processing unit 13 receives a user operation to transmit the still image to the remote terminal 20 as an input of a trigger in response to the display. The operation is, for example, an operation (e.g., a tap on a touch panel) on the still image transmission button 113 of the still image mode display screen 100b in the imaging terminal 10.

[0046] The user of the imaging terminal 10 can check the still image (before transmission to the remote terminal 20) displayed on the imaging terminal 10 to confirm whether the still image is suitable for sharing with the remote terminal 20. For example, it is possible to check whether there is defocus or blur in the still image, and as a result, it is possible to check whether the still image is suitable for confirming the front of the tunnel. If the user of the imaging terminal 10 determines that the still image is suitable for sharing with the remote terminal 20 based on the above confirmation, the user performs an operation to transmit the above still image to the remote terminal 20. If the user of the imaging terminal 10 determines that the still image is not suitable for sharing with the remote terminal 20 based on the above confirmation, the user may take another still image without performing an operation to transmit the still image to the remote terminal 20. In this case, the still image displayed on the imaging terminal 10 is not transmitted to the remote terminal 20. During the period when the user of the imaging terminal 10 checks whether the still image is suitable for sharing with the remote terminal 20, the remote terminal 20 may continue to display in the video mode. In this case, the user of the remote terminal 20 can check the state of the imaging target by the moving image without being interrupted by the still image confirmation work by the user of the imaging terminal 10. In this way, the still image processing unit 13 may input a trigger to transmit the still image to the remote terminal 20 and display it simultaneously with the moving image after the moving image is transmitted to and displayed on the remote terminal 20 by the moving image processing unit 12.

[0047] When the still image processing unit 13 receives an input of a trigger to transmit a still image to the remote terminal 20, it transmits the still image to the remote terminal 20 for simultaneous display with the moving image on the remote terminal 20. Further, the still image processing unit 13 also transmits, together with the still image, information indicating the range A of a part 103b of the still image that is largely displayed as the main display on the own terminal 10 to the remote terminal 20. When the still image processing unit 13 receives a still image from the acquisition unit 11, if only the own terminal 10 switches the display in the video mode to the display in the still image mode (when only the remote terminal 20 continues to display in the video mode), it may switch back to the display in the video mode at the timing of the above transmission. Thereby, the display modes between the imaging terminal 10 and the remote terminal 20 match.

[0048] The remote terminal 20 receives the still image transmitted from the imaging terminal 10 and the information indicating the range A, and displays them simultaneously with the moving image. The simultaneous display is, for example, the simultaneous display of the entire still image, an enlarged image of a part of the still image, and the moving image. As shown in FIGS. 2 and 3, the display of the still image on the remote terminal 20 is performed in the same manner as the display of the still image on the imaging terminal 10. That is, in the video mode, the still image 202a is displayed small as a sub-display. As shown in FIG. 3, in the still image mode, the entire still image 202b is displayed small as a sub-display, and a part 203b of the still image in the range A indicated by the received information is enlarged as the main display and displayed larger than the above sub-display.

[0049] In the still image mode, the range A of a part 103b of the still image that is enlarged and displayed as the main display may be specified (changed) even after the sharing of the still image. In this case, the still image processing unit 13 accepts the specification of the range A and displays it in the same manner as above according to the accepted range A. Further, each time the still image processing unit 13 accepts the range A, it transmits the information indicating the range A to the remote terminal 20. The remote terminal 20 receives the information indicating the range A and displays it in the same manner as above according to the received information. Thereby, a part 103 of the still image that is enlarged and displayed as the main display on the imaging terminal 10 and the remote terminal 20 is interlocked.

[0050] In the imaging terminal 10 and the remote terminal 20, in conjunction with the display of the image, the pointer position, which is the position specified by the user in the image, may be displayed. For example, when the display is in the video mode, the video image processing unit 12 receives the operation of the user of the imaging terminal 10 that designates the pointer position with respect to the main display video image 101a as shown in FIG. 2. The operation is, for example, an operation on the displayed main display video image 101a (for example, tapping the position with the user's finger F on the touch panel).

[0051] The video image processing unit 12 superimposes a display P1 indicating the designated pointer position on the main display video image 101a. Further, the video image processing unit 12 transmits information indicating the designated pointer position to the remote terminal 20. The remote terminal 20 receives the information and superimposes a display P1 indicating the pointer position indicated by the received information on the main display video image 201a.

[0052] On the other hand, the remote terminal 20 receives the operation of the user of the remote terminal 20 that designates the pointer position with respect to the main display video image 201a as shown in FIG. 2. The operation is, for example, an operation on the displayed main display video image 201a (for example, tapping the position with the cursor C).

[0053] The remote terminal 20 superimposes a display P2 indicating the designated pointer position on the main display video image 201a. Further, the remote terminal 20 transmits information indicating the designated pointer position to the imaging terminal 10. In the imaging terminal 10, the video image processing unit 12 receives the information and superimposes a display P2 indicating the pointer position indicated by the received information on the main display video image 101a.

[0054] Also, as shown in FIG. 3, even when the display in the still image mode is being performed, displays P1 and P2 indicating the pointer position may be made on a part 103b of the still image displayed as the main display. In this case, the still image processing unit 13 and the remote terminal 20 may perform the same processing as the moving image processing unit 12 and the remote terminal 20 in the case of the above-described moving image mode. Note that the designation and sharing of the pointer position or the range of the image may be performed in the sub-display in addition to or instead of the main display. For example, when it is desired to specify a range other than the part being enlarged, the location may be specified on the entire still image of the sub-display, and that location may be enlarged and displayed.

[0055] Note that if the displays of the still image and the moving image in the imaging terminal 10 and the remote terminal 20 are performed simultaneously, it is not necessarily required to be performed as described above. For example, the still image and the moving image may be displayed in the same size. Also, the enlarged display of a part of the still image may not be performed. Further, the trigger for the still image processing unit 13 to transmit the still image to the remote terminal 20 may be other than the above as long as it is based on the display of the still image in the imaging terminal 10. The above are the functions of the imaging terminal 10 according to the present embodiment.

[0056] Subsequently, the processing executed by the imaging terminal 10 according to the present embodiment will be described using the flowchart of FIG. 4. In this processing, a low-resolution moving image and a high-resolution still image obtained by imaging the same imaging target by the imaging device included in the imaging terminal 10 are acquired by the acquisition unit 11 (S01). Note that the imaging for obtaining the moving image and the still image and the acquisition of the moving image and the still image by the acquisition unit 11 may be performed continuously at appropriate timings. For example, the imaging of the still image may be performed after the imaging and display of the moving image are performed.

[0057] Subsequently, the acquired moving image is displayed on the own terminal 10 by the moving image processing unit 12. Also, the acquired still image is displayed on the own terminal 10 simultaneously with the moving image by the still image processing unit 13 (S02). Further, the acquired moving image is transmitted to the remote terminal 20 by the moving image processing unit 12 (S03). The transmitted moving image is received by the remote terminal 20 and displayed on the remote terminal 20.

[0058] Subsequently, in response to the display of the still image, a trigger for transmitting the still image to the remote terminal 20 is input by the still image processing unit 13 (S04). When the trigger is input, the still image is transmitted to the remote terminal 20 by the still image processing unit 13 (S05). The transmitted still image is received by the remote terminal 20 and displayed on the remote terminal 20 simultaneously with the moving image. The above is the processing executed by the imaging terminal 10 according to the present embodiment.

[0059] In the imaging terminal 10 according to the present embodiment, a low-resolution moving image is displayed and also transmitted to and displayed on the remote terminal 20. Also, a high-resolution still image is displayed simultaneously with the moving image. The still image is transmitted to and displayed on the remote terminal 20 when a trigger corresponding to the display is input. By these means, both the low-resolution moving image and the high-resolution still image are shared simultaneously between the imaging terminal 10 and the remote terminal 20. For example, in the evaluation of the geological state of the face of a tunnel, the overall geological state of the face can be grasped by the low-resolution moving image, and the details of the geological state of the face can be grasped by the high-resolution still image.

[0060] Also, since the images transmitted from the imaging terminal 10 according to the present embodiment to the remote terminal 20 are a low-resolution moving image and a high-resolution still image corresponding to the input of the trigger, they can be appropriately transmitted even in a poor communication environment. Also, in the imaging terminal 10 according to the present embodiment, appropriate transmission of the still image can be performed. Thus, according to the present embodiment, images such as the face of a tunnel can be appropriately shared with another terminal. Note that the images shared between the terminals as described above do not have to be images of the face of a tunnel, and may be images of any imaging target.

[0061] As in this embodiment, the still image processing unit 13 may receive a designation of a range on a still image and display an enlarged portion of the still image within the designated range. According to this configuration, it is possible to make a more appropriate trigger according to the display and perform more appropriate transmission of a still image. However, it is not necessary to perform an enlarged display of a portion of the still image.

[0062] As in this embodiment, the still image processing unit 13 may perform a display such that a still image is displayed larger than a moving image on the own terminal 10. For example, in the above-described example, the display may be a display in the still image mode. According to this configuration, it is possible to make it easier to confirm a still image by the display of the imaging terminal 10. However, the size of the display of the still image does not necessarily have to be as described above.

[0063] As in this embodiment, the still image processing unit 13 may receive a user operation to transmit a still image to the remote terminal 20 as an input of a trigger according to the display. According to this configuration, the user can confirm a still image on the imaging terminal 10 and transmit it to the remote terminal 20. However, the trigger for transmitting the still image to the remote terminal 20 may be other than the above.

[0064] The above-described imaging terminal 10 which is a terminal according to this embodiment includes an imaging device that acquires moving images and still images to be shared by imaging. However, a terminal that performs image sharing only needs to be able to acquire moving images and still images to be shared, and does not necessarily have to include an imaging device. For example, a terminal that performs image sharing may be configured to receive and acquire moving images and still images to be shared transmitted from an imaging device having a configuration different from that of the terminal.

[0065] The terminal of the present disclosure has the following configuration. [1] Acquisition means for acquiring a low-resolution moving image and a high-resolution still image obtained by imaging the same imaging target; Video processing means for displaying the moving image acquired by the acquisition means on the own terminal and transmitting it to another terminal for display; Still image processing means for displaying the still image acquired by the acquisition means on the own terminal simultaneously with the moving image, inputting a trigger corresponding to the display, and transmitting the still image to another terminal for display simultaneously with the moving image; A terminal comprising: [2] The terminal according to [1], wherein the still image processing means receives a designation of a range on the still image and enlarges and displays a portion of the still image within the designated range. [3] The terminal according to [1] or [2], wherein the still image processing means displays the still image larger than the moving image on the own terminal. [4] The terminal according to any one of [1] to [3], wherein the still image processing means receives, as an input of a trigger corresponding to the display, an operation of the user to transmit the still image to another terminal.
