Description

Technical Field

[0001] The present invention relates to a photographing system, a computer program, and the like.

Background Art

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, in the configuration described in Patent Document 1, only one user can operate one autonomous vehicle. For example, if 10 autonomous vehicles are installed in a zoo, the opening hours are 5 hours, the operation time (experience time) for each time is 10 minutes, and the time required for replacement and preparation between each time is 10 minutes.

[0007] In this case, the maximum number of users per day would be 150 (10 users every 20 minutes during the 5-hour opening period, or 300 minutes), and the number of users per unit time (e.g., 1 hour) would be 30. This number of users per unit time could be increased by increasing the number of autonomous vehicles or shortening the preparation time, but this would increase equipment or personnel costs.

[0008] Therefore, the present invention aims to provide a shooting system, etc., that can increase the number of simultaneous users while suppressing cost increases. [Means for solving the problem]

[0009] To achieve the above objective, the imaging system according to the present invention is A camera unit having a first function and a second function, The system includes control means that controls the camera unit based on operation instructions from a first user and a second user, and that can control the camera unit so that the second user can operate the second function while the first user is operating the first function. It is characterized by the following: [Effects of the Invention]

Mode for Carrying Out the Invention

[0012] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to the following embodiments. In each figure, the same members or elements are denoted by the same reference numerals, and duplicate explanations are omitted or simplified.

[0013] <Embodiment 1> FIG. 1 is a diagram showing a configuration example of a photographing system IS according to Embodiment 1. Note that some of the functional blocks shown in FIG. 1 are realized by causing a CPU or the like as a computer (not shown) included in the imaging system to execute a computer program stored in a memory as a storage medium (not shown).

[0014] However, some or all of them may be realized by hardware. As the hardware, a dedicated circuit (ASIC), a processor (reconfigurable processor, DSP), or the like can be used.

[0015] Also, each of the functional blocks shown in FIG. 1 does not have to be built in the same housing, and may be configured by separate devices connected to each other via signal paths. Note that the above description regarding FIG. 1 also applies to FIG. 11 in the same manner.

[0016] The photographing system IS includes a camera unit (camera device) CU including a holder (holding device) HA and an imaging device IA, and a transparent pipe (tubular member) TM into which the camera unit CU is inserted, and the camera unit CU is movable within the transparent pipe. Note that the entire pipe does not have to be transparent, and it may be transparent at a restricted location as long as the position and direction where the camera unit can perform photographing are restricted in advance.

[0017] The photographing system IS further includes a driving device (moving device) DRA provided in the pipe TM, a server (server device, server means) SA, and a display (display device, display means) DIA capable of displaying an image captured by the camera unit CU. The photographing system IS further includes a sensor (detection device, detection means) DEA, a control device (control means) CA, operation devices OA1 and OA2.

[0018] The holder HA is configured to detachably hold the imaging device IA so that it can move within the pipe TM, and functions as a holding means.

[0019] The imaging device IA comprises an imaging optical system and an image sensor for photographing the outside of the pipe TM, and functions as an imaging means. The imaging device IA may consist of a camera body as the housing of the imaging device and a lens that can be attached to or detached from the camera body, or the camera body and lens may be integrated into a single unit.

[0020] The drive unit DRA is configured to move the camera unit CU within the pipe TM and to rotate the camera unit CU with the direction of movement within the pipe TM as the axis of rotation.

[0021] In other words, the camera unit CU moves inside the pipe TM along its shape (a predetermined path) by the drive unit DRA. Here, the drive unit DRA functions as a moving means for moving the imaging means, which moves the imaging means along the predetermined path, and the display means displays the predetermined path.

[0022] Figures 2(A) to 2(C) illustrate possible drive configurations for the imaging device. As shown in Figure 2(A), the imaging device IA has the camera body CB and lens LA integrated inside the pipe TM, and is capable of so-called tilt rotation with the direction of movement of the imaging device IA (left and right direction in Figure 2(A)) as the axis of rotation.

[0023] Furthermore, as shown in Figure 2(B), the imaging device IA can rotate around a rotation axis perpendicular to both the direction of movement and the optical axis direction, enabling so-called pan rotation. Furthermore, as shown in Figure 2(C), the imaging device IA can rotate around the optical axis direction, enabling so-called roll rotation.

[0024] Furthermore, the lens LA contains multiple lens units (lens groups, collections of multiple lenses), and zooming is possible by changing the distance between these lens units in the optical axis direction.

[0025] The specific configurations for enabling these imaging devices IA to tilt, pan, roll, and zoom are not shown in Figures 2(A) to (C), but they can be designed appropriately using well-known techniques.

[0026] Server SA can receive images captured by imaging device IA and signals from control devices OA1 and OA2, such as controllers, located near the display DIA of a smartphone or tablet. It can also transmit these signals to imaging device IA and drive device DRA.

[0027] Furthermore, operating device OA1 functions as a first operating device, a first operating means, or a first terminal device, and operating device OA2 functions as a second operating device, a second operating means, or a second terminal device.

[0028] With this configuration, for example, a user of the IS imaging system, whether at a zoo or at home, can operate the imaging device IA and the drive unit DRA via the control device OA1 or OA2. Furthermore, the user can photograph animals or other subjects under their desired conditions.

[0029] In the block diagram shown in Figure 1, both operating devices OA1 and OA2 are treated as components of the shooting system IS. However, operating device OA1 could be a controller installed together with the display DIA in an experience booth within a facility such as a zoo, and operating device OA2 could be a terminal device such as a smartphone owned by a user at home or elsewhere outside the facility.

[0030] Thus, although the operating device OA2 is a component of the shooting system IS, it is located separately from the camera unit CU and other components. Similarly, the operating device OA1 may also be a terminal device such as a smartphone.

[0031] Furthermore, both operating devices OA1 and OA2 may be controllers installed in separate experience booths within the facility. In that case, the display DIA may consist of display 1 installed in experience booth 1 together with operating device OA1, and display 2 installed in experience booth 2 together with operating device OA2.

[0032] The imaging device IA and drive unit DRA may be connected to the server SA by wire or by wireless connection. If the imaging device IA and server SA are connected wirelessly, the imaging device IA may be equipped with a communication control component (communication chip) for communicating with the server SA. Alternatively, the communication control component may be provided inside the holder HA, and this communication control component and the imaging device IA may be connected by wire inside the holder HA.

[0033] Battery BA is a power supply device for supplying power to the drive unit DRA. In this embodiment, the imaging device IA is driven by an internal power supply, but the imaging device IA may also be configured to receive power from battery BA.

[0034] Sensor DEA is connected to the imaging device IA and the drive unit DRA, and is configured to detect the position, shooting direction, and field of view of the imaging device IA within the pipe TM. Here, sensor DEA functions as a position detection means to detect the position of the imaging device which changes with the movement means, a direction detection means to detect the shooting direction of the imaging device, and a field of view detection means to detect the field of view of the imaging device.

[0035] In this embodiment, the sensor DEA combines the functions of position detection, direction detection, and field of view detection, but it is sufficient for the shooting system IS to have these position detection, direction detection, and field of view detection functions.

[0036] Therefore, for example, the imaging device IA may have a field of view detection function, and the sensor DEA may have a position detection function and a direction detection function based on the drive information of the drive device DRA. Furthermore, the sensor DEA may include a GPS sensor.

[0037] Furthermore, the control unit CA has a built-in CPU and other components, functioning as a control means to control the operation of each part of the imaging system IS based on computer programs stored in the memory, which serves as the storage medium.

[0038] Furthermore, the control unit CA may be integrated with the server SA, or they may be separate units. In addition, the control unit CA and server SA may be installed in a physically close range to the other components of the imaging system IS (for example, within a facility such as a zoo), or in a more distant range (domestic or international).

[0039] Next, we will describe the display screen and control when multiple users (a total of two users, the first and second users) attempt to operate the imaging device IA simultaneously. The control means in this embodiment can control the camera unit based on operation instructions from the first and second users. Furthermore, while the first user is operating the first function, the camera unit can be controlled to allow the second user to operate the second function.

[0040] Figure 3 shows an example of the display screen of the display device according to Embodiment 1, and shows the screen DS of display DIA when only one user is accessing the imaging device IA. In order to count the number of users accessing the imaging device IA, for example, the control device CA can detect whether the operating devices OA1 and OA2 are being operated, and the control device CA can count the number of users based on the detection results.

[0041] In other words, if the control device CA detects that only control device OA1 or only control device OA2 is being operated, it counts the number of users as 1. Alternatively, if it detects that both control devices are being operated, the control device CA counts the number of users as 2. However, the number of control devices and the number of users that the control device CA can count are not limited to 1 or 2.

[0042] The screen DS displays the image being captured by the imaging device IA, showing the main subject MS, a cheetah, and the background image BG, which is grass. The image here is a live view image (video). The screen DS also displays the header HP, zoom range ZR, operation button OB, reference information TI, and map MI.

[0043] The header of the website displays the name of the zoo as the shooting location and the name of the main subject as the cheetah view. In addition to this information, the header may also display information such as the shooting date and the remaining time available for shooting (operating and experiencing this system).

[0044] The zoom range ZR is an image that visually indicates the zoomable range and current zoom position of the imaging device IA. More specifically, the zoom range ZR has a mark ZR1 that signifies the telephoto end, a mark ZR2 that signifies the wide-angle end, a bar ZR3 that indicates the zoomable range, and a bar ZR4 that is superimposed on bar ZR3 and indicates the current zoom position.

[0045] In other words, the display means of this embodiment can display an image showing the zoom range and current zoom position of the shooting means.

[0046] The operation button OB has multiple buttons for sending operation instructions to the imaging device IA. More specifically, the operation button OB has a shooting operation button OB1, a zoom-in button OB2 for zooming in to the telephoto side, a zoom-out button OB3 for zooming out to the wide-angle side, and a move / rotate operation button OB4. In other words, the display means can display various operation buttons for operating the shooting means.

[0047] If the display DIA is a touch-enabled display, touching each of the operation buttons OB1 to OB4 may send the corresponding instruction to the imaging device IA.

[0048] If the display DIA is a display without touch functionality, a plurality of physical buttons corresponding to the operation buttons OB1 to OB4 may be provided as the operating device OA1 (or operating device OA). When the user presses one of these physical buttons, the button corresponding to the pressed physical button among the operation buttons OB1 to OB4 may be highlighted.

[0049] If the display DIA is a touch-enabled display, the imaging device IA will continue to move to the left (right) in the plane of Figure 3 as long as the user touches the operation button OB4 and slides their finger to the left (right) while maintaining that position.

[0050] Similarly, as long as the user keeps their finger touching the operation button OB4 and slides it upwards (downwards), the imaging device IA continues to tilt upwards (downwards) in the plane of Figure 3.

[0051] If the display DIA is a non-touch display, the operation buttons OB4 on the operating devices OA1 and OA2 correspond to a directional pad or similar. By operating this directional pad, the user can move the imaging device IA left or right or tilt it.

[0052] Furthermore, if the display DIA is a touch-enabled display, the control device CA and imaging device IA may be able to accept both touch operations on the display DIA and operations by the operating devices OA1 and OA2.

[0053] Reference Information TI displays information that assists in photography. Specifically, the display means displays information that assists in photography by the photography means and information about the main subject. In this embodiment, the word "Hint" is displayed to indicate that it is information that assists in photography, an exclamation mark is displayed to attract attention, and the words "When the animal starts moving, it's a photo opportunity!!" which are specific assistive information, are displayed. In other words, the information that assists in photography by the photography means includes information that indicates the timing of the shot.

[0054] Reference Information TI may not only contain information that assists in photography, but may also display information about the main subject, such as the name and ecology of the organism, if the main subject MS is a living organism. In other words, information about the main subject includes information about the organism's ecology.

[0055] Furthermore, both information that assists in photography and information about the main subject may be displayed. Information about the main subject may be displayed not only as a simple statement, but also in a quiz format (question format).

[0056] Map MI displays information such as the movement path and current position of the imaging device IA, the shooting direction, and the field of view. More specifically, Map MI includes MI1, which is an image showing the movement path (predetermined path) of the imaging device IA; Mark MI2, which indicates the start position of the movement path MI1; and Mark MI3, which indicates the end position.

[0057] Map MI further includes a mark MI4 indicating the current position of the imaging device IA, a mark MI5 indicating the imaging direction and field of view of the imaging device IA, and an image MI7 indicating other areas. The movement path MI1 of the imaging device IA is the same as the installation path of the pipe TM.

[0058] When a user experiences a shooting tour using the IS shooting system, Mark MI2 corresponds to the initial position of the camera unit CU in that tour. The user sends instructions to the drive unit DRA using the control device OA1 or control device OA2.

[0059] Based on this instruction, the control unit CA controls the drive unit DRA to move the camera unit CU within the pipe TM. Then, the control unit CA controls the display DIA so that marks MI4 and MI5 also move on the map MI in accordance with the movement of the camera unit CU.

[0060] The camera unit CU's position detection may be performed by the sensor DEA, or it may be performed by the drive unit DRA itself or the control device CA calculating the camera unit CU's position from information such as the drive amount of the drive unit DRA.

[0061] When the user stops moving the camera unit CU and prepares to take a picture, the user sends an instruction to the imaging device IA using the operating device OA1 or operating device OA2 to adjust the field of view of the imaging device IA. Based on this instruction, the control device CA controls the imaging device IA to adjust the field of view, and the control device CA controls the display DIA so that the mark MI5 also changes in accordance with the adjustment of the field of view.

[0062] Figures 4(A) and 4(B) show examples of changes in the field of view on the display screen of the display device according to Embodiment 1. As shown in Figures 4(A) and 4(B), the control device CA controls the display DIA so that the length of one side (base) of the isosceles triangle mark MI5 changes in accordance with the adjustment of the field of view.

[0063] Figure 4(A) shows the mark MI5 in the telephoto end state, and Figure 4(B) shows the mark MI5 in the wide-angle end state. Thus, in this embodiment, the display means displays marks indicating the direction detection result and the field of view detection result. Furthermore, the display means displays the marks so that their orientation changes according to the direction detection result.

[0064] The shape of Mark MI5 may change while maintaining its area, or both its height and base may change, or only the base may change while the height remains fixed. Furthermore, Mark MI5 is not limited to a triangle; it may also be a sector or other shape. If Mark MI5 is a sector, the bisector of the sector indicates the shooting direction, and the arc length corresponds to the size of the field of view.

[0065] Thus, the marks used to indicate the direction detection result and the field of view detection result have a triangular or sector shape. Furthermore, the display means displays the mark such that the length of some sides or arcs changes according to the field of view detection result. Alternatively, as mentioned above, the display means may display the mark while maintaining its area, so that the length of some sides or arcs changes according to the field of view detection result.

[0066] The detection of the shooting direction of the camera unit CU (imaging device IA) may be performed by the sensor DEA, or it may be performed by the control device CA calculating the shooting direction of the camera unit CU from information such as the drive amount of the drive device DRA and the shape of the pipe TM.

[0067] The shooting direction refers to the direction in which the imaging device IA (more specifically, the lens) is facing, i.e., the optical axis direction. However, it is also possible to detect directions other than the optical axis direction. For example, it is possible to detect the amount of tilt (the direction of movement of the camera unit CU, i.e., rotation with the extension direction of the pipe TM as the axis of rotation) and to detect the tilt direction in which the camera unit CU is facing within the tilt drive range.

[0068] Furthermore, the pan drive amount may be detected, allowing the camera unit CU to detect the direction it is facing within the pan drive range. Similarly, the roll drive amount may also be detected, allowing the camera unit CU to detect the direction it is facing within the roll drive range.

[0069] The angle of view of the camera unit CU (imaging device IA) may be detected by the sensor DEA, or the imaging device IA may transmit information about its current angle of view to the control device CA, and the control device CA may detect the angle of view based on that information. In addition, the user may be notified by voice or text that the experience tour will end when the mark MI4, which indicates the position of the imaging device IA, overlaps with the mark MI3.

[0070] Thus, in this embodiment, when only the first user has access to the camera unit, the camera unit is controlled so that the first user can operate the first and second functions. Furthermore, if a second user accesses the camera unit while the first user is accessing it, the image being captured by the camera unit is displayed to the second user.

[0071] Figure 5 is a flowchart showing the control when the number of users changes to multiple people according to Embodiment 1, and shows the processing steps for controlling a camera unit having a first function and a second function.

[0072] Furthermore, the CPU and other components within the control unit CA execute computer programs stored in memory, sequentially performing the actions shown in the flowchart of Figure 5.

[0073] As shown in Figure 5, in step S1, the control device CA monitors whether there are multiple users accessing the imaging device IA, which is the imaging system IS, using the methods described above. Specifically, for example, it determines whether a second user other than the first user is attempting to access the system. In this step, step S1 functions as a reception step that receives operation instructions from both the first and second users.

[0074] If there is only one user accessing the imaging device IA, that user can operate all of the operation buttons OB1 to OB4 on the display DIA shown in Figure 4, as well as the operation buttons on the corresponding control devices OA1 or OA2.

[0075] Let's consider the case where, in step S1, it is detected that there are multiple users, that is, while the first user is accessing the imaging device IA and experiencing imaging, the second user later attempts to access the imaging device IA.

[0076] In this case, as step S2, the control device CA first checks whether the second user has made a request other than screen viewing. Here, we consider the case where the second user is outside the facility, such as at home, and the operating device OA2 is a terminal device such as a smartphone owned by the second user.

[0077] Figure 6 shows an example of the display screen of the terminal device according to Embodiment 1 before access, and shows an example of the screen TDS of a smartphone TA (operating device OA2, terminal device) owned by a second user who is trying to access the imaging device IA.

[0078] The TDS screen displays the Live View Window (LVW), which shows the live view image from the imaging device (IA), and the Operation List (OL), which allows the user to select the desired operation. The Operation List (OL) displays text information indicating the desired operation (for example, "Zoom Operation").

[0079] The second user selects the operation they want to perform by touching the text information displayed in the operation list OL. For example, if they only want to view the screen, they touch the cell labeled "View Screen Only". On the other hand, if they want to view the screen while also performing the shooting operation themselves, they touch the cell labeled "Shooting Operation".

[0080] In step S2, the control device CA checks whether the second user has made a request other than screen viewing. More specifically, information indicating the result of the second user touching the operation list OL on the smartphone TA is sent from the smartphone TA to the control device CA via the server SA.

[0081] If the second user only requests to view the screen, that is, if the result in step S2 is determined to be No, the process proceeds to step S3, where the control device CA causes the second user to display, for example, the screen shown in Figure 7 on the screen TDS of their smartphone TA via the server SA.

[0082] Figure 7 shows an example of the display screen after accessing the terminal device according to Embodiment 1. Unlike the screen DS shown in Figure 3, the operation buttons OB1 to OB4 are not displayed in the screen TDS shown in Figure 7, and the second user can only view the screen.

[0083] Next, in step S4, the control device CA causes the first user's display DIA screen DS to display the screen shown in Figure 8 via the server SA. After step S4, the process returns to step S1.

[0084] Figure 8 shows an example of the display screen of the display device according to Embodiment 1 when another user is accessing it. In the screen DS shown in Figure 8, access information AI indicating that another user is accessing the screen DS is additionally displayed on the screen DS shown in Figure 4.

[0085] In other words, the display means can display information to the first user indicating that the second user is accessing the camera unit. By displaying additional access information AI, the first user can understand that the second user is accessing the imaging device IA, that is, they are viewing the same screen.

[0086] On the other hand, if the control device CA confirms in step S2 that the second user has made a request other than screen viewing, it determines "Yes" and proceeds to step S5. In step S5, the control device CA confirms the operation requested by the second user.

[0087] More specifically, the control device CA, via the server SA, confirms which operation the second user performed from each operation in the operation list OL in Figure 6 (the cells representing each operation other than "screen viewing only").

[0088] For example, let's consider the case where the second user selected only the shooting operation (i.e., the second user only touched the "Shooting Operation" cell in the operation list OL in Figure 6). In that case, in step S6, the control device CA displays the screen shown in Figure 9 on the screen TDS of the second user's smartphone TA via the server SA.

[0089] Figure 9 shows an example of obtaining operational privileges on the display screen after accessing the terminal device according to Embodiment 1. Unlike the screen DS shown in Figure 4, the screen TDS shown in Figure 9 only displays the shooting operation button OB1.

[0090] In other words, when the first user has the authority to operate both the first and second functions, the display means displays the first and second operation buttons. However, when the authority to operate both the first and second functions is transferred from the first user to the second user, the display means changes the display format of the second operation button.

[0091] Furthermore, changing the display format here includes, for example, turning off the display, or changing it to, for example, graying it out or changing it to a predetermined color, to indicate that it is effectively unusable.

[0092] At this time, the second user can send a shooting command to the imaging device IA via the server SA by touching the shooting operation button OB1 on the screen TDS, which is the touch screen shown in Figure 6, and thus be able to photograph the main subject, such as an animal.

[0093] Furthermore, step S6 functions as a control step that controls the camera unit so that the second user can operate the second function while the first user is operating the first function. Also, in step S6, if the second user accesses the camera unit while the first user is accessing it and requests permission to operate the second function, the camera unit is controlled so that the second user can operate the second function.

[0094] Next, in step S7, the control device CA causes the first user's display DIA screen DS to display a screen as shown in Figure 10 via the server SA.

[0095] Figure 10 shows an example where the operation authority on the display screen of the display device according to Embodiment 1 has been transferred. In the screen DS shown in Figure 10, the display of the shooting operation button OB1 has been removed from the screen DS shown in Figure 4.

[0096] In other words, it can be seen that the authority to perform the shooting operation has been transferred from the first user to the second user. However, the authority to perform other operations remains with the first user. Thus, in this embodiment, the display means can display information to the first user indicating that the second user is requesting permission to perform the operation of the second function.

[0097] In this scenario, the first user can capture the main subject, such as an animal, in their desired composition by, for example, moving the camera, and then view it on the on-screen display (DS). Simultaneously, the second user can monitor the changes in composition made by the first user and take a picture at their desired timing.

[0098] In other words, even with only one imaging device IA, multiple users, such as a first user and a second user, can operate it simultaneously at the same time, and each can carry out their own imaging experience tour.

[0099] Furthermore, the display modes of screen TDS shown in step S6 and screen DS shown in step S7 are not limited to the above pattern (the pattern in which only the permission for shooting operations is transferred). For example, if the second user requests operations other than shooting, such as movement operations, in step S5, the operation buttons corresponding to those movement operations may be displayed on screen TDS, and only the operation buttons corresponding to shooting operations may be displayed on screen DS.

[0100] In step S8, the control device CA determines whether the above-mentioned photo shooting experience tour has been conducted for the predetermined time. If the determination in step S8 is No, the process returns to step S1. If the determination is Yes, the process proceeds to step S9. In step S9, the screen DS and screen TDS are notified, respectively, by text or image information, that the predetermined time has elapsed and the photo shooting experience has ended. This notification may also be given by audio information.

[0101] Furthermore, the operation authority may be transferred from the first user to the second user as requested by the second user, or it may not be. For example, if it is confirmed in step S5 that the second user has requested a shooting operation, in step S6 the TDS screen of the second user's smartphone TA will be in the display format shown in Figure 7 until a predetermined time (e.g., 3 minutes) has elapsed. After the predetermined time has elapsed, it may be changed to the display format shown in Figure 9.

[0102] In other words, if a second user accesses the camera unit while a first user is accessing it and requests permission to operate a second function, the camera unit may be controlled so that the second user can operate the second function after a predetermined period of time has elapsed.

[0103] At that time, the display format on the screen TDS may be changed, meaning that a predetermined time has elapsed and shooting operations are now possible, or that shooting operations are not possible until a predetermined time has elapsed.

[0104] Furthermore, the screen DS for the first user shall be displayed in the format shown in Figure 8. Additionally, the access information AI may display text or image information indicating that the second user is requesting a photo shoot, and that after the predetermined time has elapsed, the authority to perform the photo shoot will be transferred from the first user to the second user.

[0105] After the predetermined time has elapsed, the display mode may be changed from the one shown in Figure 8 to the one shown in Figure 10. By having the control device CA perform this control, it is possible to prevent the first user from being surprised when some of the operating privileges they initially had are suddenly transferred to other users.

[0106] In this case, the specified time, i.e., the grace period until the transfer of control rights, may be changed depending on the payment amount. That is, for example, if the second user pays the specified amount, or if the first user permits the transfer of control rights before the grace period expires, the grace period (specified time) may be shortened or eliminated. That is, if the second user pays the specified amount, the specified time may be shortened.

[0107] Furthermore, if the first user authorizes the transfer of control before the above grace period expires, the first user may be refunded a portion of the usage fee required for the series of shooting experiences using the IS shooting system. Alternatively, in that case, the shooting experience time that can be experienced in exchange for paying the usage fee may be extended beyond the prescribed time.

[0108] Furthermore, if a second user requests one operation from the operation list OL, a predetermined amount may be requested; if two operations are requested, for example, double that amount may be requested; and if more operations are requested, an even larger amount may be requested.

[0109] In other words, the control means may have a function to calculate the usage fee required to operate the camera unit for a predetermined period of time, and may calculate the usage fee based on the number of functions of the camera unit for which operation rights are requested.

[0110] If the control device CA detects that the amount has been paid via the server SA, the control device CA may grant operational privileges in accordance with the request of the second user.

[0111] In other words, if a first user is accessing the camera unit and a second user accesses the camera unit and requests permission to operate a second function, the camera unit may be controlled so that the second user can operate the second function after paying a predetermined amount.

[0112] As described above, the imaging system IS of this embodiment has a display DIA that displays the image being captured by the imaging device IA, a predetermined path, and the position detection result, direction detection result, and field of view detection result of the camera unit CU (imaging device IA). Therefore, the shooting position and shooting direction can be visually grasped more easily than in conventional systems.

[0113] Furthermore, the differences in the display formats of screen DS and screen TDS explained in Figures 7 to 10 were the presence or absence of access information AI and the type (presence or absence, number) of operation buttons displayed among the operation buttons OB, but the display format may be changed to show other differences as well.

[0114] For example, the screen viewed by a user with imaging privileges for the imaging device IA (display DIA or terminal device screen) may display information related to the imaging device IA, such as the f-number, which may differ from the screen viewed by other users. In that case, operation buttons for adjusting the screen's color tone may also be displayed.

[0115] Furthermore, while the access information AI in Figure 8 only displays textual information indicating that another user is viewing the screen (the text "Another user is accessing" in Figure 8), the access information AI is not limited to this.

[0116] For example, the access information AI could display the number of users currently accessing or waiting to access the service. Alternatively, it could display text information about functions or operations that other users are requesting permission to transfer (e.g., "Another user is requesting permission to take a photo"). Furthermore, it could display a button for the user who sees this text information to choose whether to agree to transfer the function as requested.

[0117] In other words, if a first user is accessing the camera unit and a second user accesses the camera unit and requests permission to operate a second function, the first user is notified that permission has been requested. Then, if the first user accepts the request for permission, the camera unit may be controlled so that the second user can operate the second function.

[0118] [Embodiment 2] Figure 11 shows an example configuration of the imaging system IS according to Embodiment 2. The difference between Embodiment 1 and this embodiment is that it includes multiple camera units CU1 and CU2. Multiple holders HA1 and HA2 each have the same configuration, and multiple imaging devices IA1 and IA2 each have the same configuration. However, these configurations do not have to be the same as each other.

[0119] Furthermore, in the explanation of Figure 12 described later, we will describe an example in which, in addition to the camera units CU1 and CU2 shown in Figure 11, there are camera units CU3, CU4, and CU5, which are not shown in Figure 11. In other words, we will describe an example in which a total of five camera units are installed inside the pipe TM.

[0120] Furthermore, all five of these camera units may be movably mounted within the same pipe TM, or some may be movably mounted within different pipes. Also, some or all of the camera units may move along roads or rails instead of moving within pipes.

[0121] Furthermore, Embodiment 2 differs from Embodiment 1 in that it has an imaging device IA3 that is capable of capturing images with a wider field of view than the imaging devices provided by each camera unit, and is installed to capture an overhead view of a predetermined location (such as an animal enclosure where the pipes TM are installed).

[0122] Figure 12 shows an example of the display screen of the display device according to Embodiment 2, and assumes a scenario in which a first user is viewing an image captured by the imaging device IA1 on the display DIA. The screen DS1 of the display DIA in this case is shown in Figure 12.

[0123] The first user's screen DS1 displays the image captured by camera unit CU1 (imaging device IA1), and in addition, images captured by other camera units (imaging devices) are displayed on screens DS2, DS3, DS4, and DS5.

[0124] Figure 12 shows a giraffe as the main subject MS, and the giraffe's habitat (exhibition area, habitat) as the background image BG. The display DIA has a touch panel function, and the first user can perform operations corresponding to each operation button by touching the operation buttons OB.

[0125] Furthermore, the first user-facing operating device OA1 may also be provided with physical operating buttons corresponding to each of the operating buttons on the operating button OB shown in Figure 12.

[0126] The control buttons OB include a shooting button OB1, a zoom-in button OB2, and a zoom-out button OB3. The control buttons OB further include a rightward movement button OB5 and a leftward movement button OB6, up-down movement (tilt) buttons OB7 and OB8, a rightward rotation (pan) button OB9 and a leftward rotation (pan) button OB10, and roll buttons OB11 and OB12.

[0127] The control button OB further includes a camera jump control button OB13, a directional pad button OB14, and a select button OB15. Each control button transmits instructions corresponding to its name to the camera, drive unit, server, etc. The camera jump control button OB13, directional pad button OB14, and select button OB15 will be described later.

[0128] Furthermore, these operation buttons OB1 to OB15 are buttons for controlling various functions of the camera unit, and one of these functions can be called the first function, and the other function can be called the second function.

[0129] Furthermore, for example, the first and second functions include either a zoom function or a shooting function of the imaging device. In addition, as in this embodiment, a rotation means having at least one of the following functions may be provided: a tilt function for tilting the imaging device, a pan function for panning the imaging device, and a roll function for rolling the imaging device. In that case, the first and second functions may include at least one of the following functions: a zoom function, a shooting function, a tilt function, a pan function, and a roll function.

[0130] Furthermore, if, as in this embodiment, the system further includes a means for moving the camera unit, the first and second functions include at least one of a zoom function, a shooting function, and a movement function.

[0131] Furthermore, operation buttons OB1 to OB15 function as first operation buttons for operating the first function and second operation buttons for operating the second function. Additionally, if the display DIA has a touch panel function, the display means can display the first and second operation buttons. The display means is also positioned so that the first user can operate the first and second operation buttons.

[0132] The first user can view screen DS1 and operate the various control buttons to achieve the desired composition, then touch the shooting operation button OB1 (or press the shooting operation button located on the control device OA1) to photograph the main subject MS.

[0133] The DS1 screen also displays the Operation Permission List (OPL) and Autopilot Information (AP). The Operation Permission List (OPL) displays a list of operations that the user is currently able to perform, i.e., operations for which they have permission. For example, the Operation Permission List (OPL) shown in Figure 12 indicates that the first user has been granted permission to perform zoom, movement, shooting, and tilt / pan / roll operations.

[0134] The following describes the case where a user other than the first user accesses the imaging device IA in the state shown in Figure 12. Note that the processing in Embodiment 2 is basically the same as the processing shown in the flowchart in Figure 5, and the screen displayed to the other user is the same as the screen TDS shown in Figure 6.

[0135] Suppose a user other than the first user selects the "shooting operation" request on the TDS screen shown in Figure 6. This information is transmitted wirelessly from the smartphone TA (terminal device) to the control device CA via the server SA.

[0136] Figure 13A is a diagram showing an example of a state where another user is accessing the display screen of the display device according to Embodiment 2. When the above information is received, the control device CA displays access information AI, indicating that another user is accessing the screen DS1 of the first user, and operation permission information OPI, which asks whether to delegate the shooting operation permission, on the first user's screen DS1 as shown in Figure 13A.

[0137] In other words, the Operation Permission Information (OPI) is textual information that indicates which operation permission another user is requesting (for example, "Do you want to delegate the shooting operation permission?" in Figure 13A).

[0138] If the first user agrees to the delegation of operation rights displayed in the operation rights information OPI, the first user touches the OK button OB15 or presses a physical button on the operation device OA1 that corresponds to the OK button OB15. When the control device CA detects this touch or press, the control device CA grants the shooting operation rights to another user and changes the display on the screen DS1 to the form shown in Figure 13B.

[0139] Figure 13B shows an example of a display that follows Figure 13A. In the display format shown in Figure 13B, the operation authority information OPI is removed from the display format shown in Figure 13A, and the color of the cell containing the text of the delegated operation (in Figure 13B, "shooting operation") in the operation authority list OPL is changed. Furthermore, the color of the operation button corresponding to the delegated operation (in Figure 13B, the shooting operation button OB1) may also be changed.

[0140] Such changes allow the first user to visually understand that some of their operational authority has been transferred. In Figure 13A, if the control device CA determines that the first user did not consent to the transfer of operational authority if the confirmation button OB15 is not touched or the corresponding physical button is not pressed after a predetermined period of time has elapsed with the operational authority information OPI displayed. The control device CA may then notify the smartphone TA, which is the terminal device of the other user, of this fact.

[0141] Figure 14 is a diagram illustrating the camera jump function in the display screen of the display device according to Embodiment 2, and the function of the camera jump operation button OB13 will be explained using Figure 14.

[0142] Screen DS2 displays the image captured by camera unit CU2, and screen DS3 displays the image captured by camera unit CU3. Additionally, screen DS4 displays the image captured by camera unit CU4, and screen DS5 displays the image captured by camera unit CU5.

[0143] As shown in Figure 14, screens DS4 and DS5 display nearly identical images because camera units CU4 and CU5 were stopped and taking pictures in approximately the same position. Each screen displays not only the image taken by the corresponding camera unit, but also information indicating whether each camera unit is being operated.

[0144] In other words, in Figure 14, for example, screen DS2 displays "Player A is piloting," screen DS3 displays "Player B is piloting," and screens DS4 and DS5 display "Available" and "Available." Here, "Available" means that the player is not being piloted.

[0145] Thus, in this embodiment, the camera unit comprises a first camera unit and a second camera unit that can be driven simultaneously, and the display means comprises a first display means capable of displaying a first image captured by the first camera unit.

[0146] Furthermore, when the first user has operational authority over the first camera unit and the second user has operational authority over the second camera unit, the first display means can display the first image (screen DS1) being captured by the first camera unit.

[0147] Furthermore, at this time, the second image (screens DS2, DS3, DS4, DS5, etc.) captured by the second camera unit can also be displayed. In addition, the first display means can display the second image smaller than the first image.

[0148] Furthermore, the indication of whether each camera unit is being operated may be conveyed not only through text information, but also through image information, audio information, or a combination thereof.

[0149] It is conceivable that the first user viewing screens DS2, DS3, DS4, and DS5 might find that the main subject MS displayed on the other screens is closer to their desired composition than the main subject MS displayed on screen DS1, i.e., the main subject MS they are photographing themselves.

[0150] In that case, if the first user wants to display another screen on their main screen DS1, the first user first touches the camera jump operation button OB13 or presses the corresponding physical button provided on the control device OA1.

[0151] The control device CA, upon detecting the operation, displays the camera selection frame CSF on screen DS1. The first user selects the screen they wish to enlarge from screens DS2, DS3, DS4, and DS5 using the camera selection frame CSF by pressing the directional key button OB14 or the corresponding physical button on the control device OA1.

[0152] The selection is then confirmed by pressing the confirmation button OB15 or the corresponding physical button on the operating device OA1.

[0153] When the control device CA detects that a screen to be enlarged has been selected on the main screen DS1, the control device CA enlarges and displays the selected other screen on screen DS1. For example, in Figure 14, if the first user selects to enlarge screen DS2 using the camera selection frame CSF, the image in screen DS2 will be enlarged and displayed on screen DS1.

[0154] In other words, when a first user requests access to the second camera unit, the first display means displays the second image in place of the first image in the area where the first image was previously displayed.

[0155] At this time, the user operating the camera unit CU2 corresponding to screen DS2 (referred to as "Person A" in Figure 14) will see the message "Another user is accessing" displayed on the screen of their terminal as access information AI.

[0156] In this state, the first user can only view the enlarged image of screen DS2 displayed on the main screen DS1, but it may be possible to allow the first user to request permission to operate the camera unit CU2.

[0157] In this way, if a user prefers an image captured by a camera unit (imaging device) other than the one they have control over, they can switch to displaying that image on the main screen for viewing.

[0158] In this embodiment, an example was described in which the user operates the camera jump operation button OB13, that is, in order to enlarge and display another image based on the user's will or wishes. However, it is not limited to this, and for example, all of the user's operational rights (including screen viewing) may be forcibly transferred to another camera unit after a predetermined time has elapsed, so that it appears as if the user is jumping to another camera unit after a predetermined time has elapsed.

[0159] Furthermore, the autopilot information AP shown in Figures 12 to 14 is text information indicating whether the camera unit is in autopilot mode, and it also functions as a button to switch that mode ON or OFF.

[0160] For example, when the first user touches the autopilot information AP or presses the corresponding physical button on the control device OA1, the control device CA switches the camera unit alternately between autopilot mode and manual control mode.

[0161] The autopilot information AP shown in Figures 12 to 14 indicates that the autopilot mode is OFF. When the autopilot mode is ON, the camera unit automatically moves within the pipe TM and performs tilt operations on its own. This allows the user to quickly concentrate on operating the shooting operation button OB1, i.e., pressing the shutter, when the desired composition is achieved.

[0162] [Embodiment 3] Figure 15 shows an example of the configuration of the camera unit CU in Embodiment 3. As shown in Figure 15, the camera unit CU in this embodiment includes a plurality of imaging devices (IA1, IA2, IA3, IA4, IA5) and a holder HA that holds the plurality of imaging devices.

[0163] Each imaging device is equipped with a lens (LA1, LA2, LA3, LA4, LA5) and a camera body (CB1, CB2, CB3, CB4, CB5). When the camera unit CU moves along the pipe TM, the multiple imaging devices move as a single unit, that is, while the distance between them remains constant.

[0164] Each imaging device can be accessed and operated by a different user. In the example shown in Figure 15, imaging devices IA1 and IA5 are oriented in the direction of movement of the camera unit CU (left-right direction in Figure 15), and their imaging direction is fixed in that direction of movement. Imaging devices IA2, IA3, and IA4 are oriented in the direction of the side of the pipe TM (direction in Figure 15), and their imaging direction can be tilted.

[0165] Regarding the allocation of operational privileges for each user, the first user can be assigned the authority to perform shooting and zoom operations on imaging devices IA1 and IA5, and to move the camera unit CU. The second user can be assigned the authority to perform shooting, zoom operations, and tilt operations on imaging device IA2.

[0166] Similarly, user 3 can be assigned the authority to operate the imaging device IA3, including shooting, zooming, and tilting. Similarly, user 4 can be assigned the authority to operate the imaging device IA4, including shooting, zooming, and tilting. By assigning these operational permissions, the second users, 3 and 4, will entrust the movement of the camera unit CU to the first user.

[0167] Then, each user can concentrate on taking images using the imaging devices IA2, IA3, and IA4, for which they have control. Conversely, the first user can only take images in the direction the camera unit CU is moving, but they can move the camera unit CU freely, allowing each user to experience taking images at the same time.

[0168] Thus, in this embodiment, the camera unit has a first imaging device and a second imaging device, as well as a holding device for holding the first and second imaging devices. Furthermore, the control means can control the camera unit so that a second user can operate the second imaging device while a first user is operating the first imaging device.

[0169] In the above embodiment, the camera unit was made to move along a predetermined path by moving through a closed space such as a transparent pipe. However, it is not limited to movement within a pipe, and may also be made to move through an open space. That is, the camera unit may be made to move along a predetermined path such as a road or rail.
