[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0010] First, the problem of a conventional imaging system composed of a control device such as a lens device and at least one display device capable of communicating with the control device will be described. Information transmitted and received between devices constituting the imaging system is image and video information, and it is assumed that a general video information transmission and communication protocol can be used, so menu information such as device status and settings may not be applicable. In addition, in an imaging system, multiple display devices (external UIs) having a display unit other than a lens, such as accessories for operating a camera VF or lens, and display-only devices such as monitors and tablets, may be connected. In recent years, with the diversification of shooting applications, the devices connected to lenses have also become more diverse, and there are many cases where simply displaying predetermined information on a display device connected for communication does not necessarily provide the information that is necessary for, for example, a photographer.

[0011] In an imaging system, operators such as a cameraman who operates the cameras and lenses, a video engineer (VE) who adjusts the cameras and various video equipment, and a switcher who switches screens during video production, all operate the system while checking display devices corresponding to the various devices.

[0012] In addition, in a shooting environment, various UIs may be configured in various places (devices), such as camera VFs and camera accessories, lenses and lens accessories, VE (Video Engineering) equipment, switcher equipment, etc. In particular, in recent years, the number of devices that can be connected to PCs and tablets has been increasing, and these devices may also be used as UIs for the imaging system.

[0013] The optimal display items for each of these various display devices are different. For example, a cameraman needs information about shooting operations, while VE and switchers need information that gives an overview of the entire system. Also, the display format and information that is best suited for each type of UI differs. For example, a large display is suitable for displaying a list, and since the VF displays images, displaying too much information on top of each other can have an adverse effect on shooting.

[0014] Also, depending on the camera and other interfaces, some information can be sent and received, while others cannot. Also, whether or not information can be sent and received may depend on the product generation and firmware version. In any case, it is necessary to make it possible to display the necessary information while avoiding duplication of information display between devices that are connected for communication.

[0015] To improve operability and make shooting more efficient, the display of the external UI must always provide necessary information to the person viewing the UI. These UIs should have a display format that matches the display capabilities of the UI, and information that matches the person viewing the UI and the type of the UI itself in the entire imaging system. For this reason, it is desirable for an information holding device that holds information to be able to identify the display unit of the device with which it is connected for communication, and to determine the content to be displayed on the external UI based on the identified information.

[0016] Each embodiment will be described in detail below. EXAMPLES

[0017] First, an imaging system 10 according to a first embodiment of the present invention will be described with reference to FIG. 1. FIG. 1 is a block diagram of the imaging system 10. The imaging system 10 is configured to include a lens device 100, a camera device (imaging device) 200, and an operation device 300. However, this embodiment is not limited to this, and other units such as a display-only device or a VE system (video engineer) may be connected to the lens device 100. In this embodiment, the lens device 100 is described as an information holding device (control device), and the camera device 200 and the operation device 300 are each external UIs (units including a display device (display unit)). In this embodiment, the operation device 300 is, for example, an accessory that operates the zoom lens of the lens device 100, but is not limited to this.

[0018] First, the lens device 100 will be described. The lens device 100 has an L communication unit 101, an L calculation unit (processing unit) 102, and an L display unit 107. The lens device 100 also has a lens group (zoom lens, focus lens), an aperture, and an operation unit (none of which are shown). The L communication unit 101 is a communication unit that communicates with other communication connection devices such as the camera device 200 or the operation device 300. The L communication unit 101 transmits data input from the L calculation unit 102 to other communication connection devices that are connected to the L communication unit, and also outputs received data from other communication connection devices to the L calculation unit 102. In this embodiment, the L communication unit 101 outputs at least identification information received from other communication connection devices to the L calculation unit 102. The L communication unit 101 also outputs C display data, which will be described later, to the camera device 200, and also outputs D display data to the operation device 300.

[0019] The L calculation unit 102 is a control unit such as a CPU, and has at least an L role specification unit 103, an L display specification unit 104, an L display content determination unit 105, and an L display information creation unit 106. The L calculation unit 102 also outputs L display data, which will be described later, to the L display unit 107, and outputs display data other than the L display data (C display data, D display data) to the L communication unit 101 (causing the L communication unit 101 to transmit the display data to the camera device or the operation device 300).

[0020] The L role identification unit 103 performs a role identification process to identify the role (type of user) of a user (operator or photographer) who operates each device in the imaging system 10 including the lens apparatus 100. More specifically, the L role identification unit 103 identifies the role (role information) of the operator based on the identification information of each device (each unit) input from the L communication unit 101. The identification information includes information regarding the operation by the operator. The identified role information is handled by the L display content determination unit 105. Note that a detailed processing flow of the role identification process will be described later with reference to FIG. 3. Also, the term "role" and role information will be described later with reference to FIGS. 8(a) to (c).

[0021] The L display specification unit 104 performs a display specification process for specifying display information such as the presence or absence of a display unit of each device and the display capacity of the display unit, based on the identification information of each device input from the L communication unit 101 in the imaging system 10 including the lens apparatus 100. The specified display information is handled by the L display content determination unit 105. Note that a detailed processing flow of the display specification process will be described later with reference to FIG.

[0022] The L display content determination unit 105 determines what to display on which display unit of the imaging system 10, based on either only the display unit identified by the L display identification unit 104, or combination information including the role information identified by the L role identification unit 103. Specifically, a display content determination process is performed to determine the content to be displayed on the target external UI and its own UI (L display unit 107). The determined display content information is handled by the L display information creation unit 106. A detailed processing flow of the display content determination process will be described later with reference to FIG. 4.

[0023] The L display information creation unit 106 performs a display information creation process for creating display data to be displayed on an external UI based on the display content information determined by the L display content determination unit 105. The L display information creation unit 106 creates, for example, C display data for display on the camera device 200 and D display data for display on the operation device 300, and outputs these to the L communication unit 101. A detailed processing flow of the display information creation process will be described later with reference to FIG. 5. The L display information creation unit 106 creates not only display data for the external UI, but also L display data to be displayed on the L display unit 107, which will be described later. The created L display data is output to the L display unit 107.

[0024] The L display unit 107 is a display device, and is at least a UI that is visible to the user. It displays the L display data input from the L calculation unit 102. The display device is, but is not limited to, an LCD or an organic EL. In this embodiment, the lens device 100 does not necessarily have to have the L display unit 107.

[0025] Next, the camera device 200 will be described. The camera device 200 is an imaging device equipped with an imaging unit, and is configured to include a C communication unit 201, a C calculation unit 202, and a C display unit 207. The C communication unit 201 is a communication unit that communicates with other communication connection devices such as the lens device 100. The C communication unit 201 transmits data input from the C calculation unit 202 to other communication connection devices that are connected to the C communication unit 202, and also outputs data received from other communication connection devices to the C calculation unit 202. In this embodiment, the C communication unit 201 outputs at least C display data received from the lens device 100 to the C calculation unit 202. In addition, the C communication unit 201 outputs identification information input from the C calculation unit 202 to the lens device 100.

[0026] The C calculation unit 202 is a control unit such as a CPU, and has at least a C display information creation unit 206. The C calculation unit 202 also outputs C display data input from the C communication unit 201 to the C display unit 207, and outputs its own identification information to the C communication unit 201. The C display information creation unit 206 converts the C display data input from the C communication unit 201 into display data that matches the display format of the C display unit 207, and outputs it to the C display unit 207. The C display unit 207 is a display device, and is at least a UI that is visible to the user, such as a camera VF. The C display unit 207 displays the display data converted by the C display information creation unit 206. The display device is, but is not limited to, an LCD or an organic EL.

[0027] Next, the operation device 300 will be described. The operation device 300 is a device for operating the lens device 100, and is used to operate, for example, a zoom lens and a focus lens (not shown) configured in the lens device 100. The operation device 300 is configured with a D communication unit 301, a D calculation unit 302, and a D display unit 307. Note that in this embodiment, the operation device 300 is an operation device capable of operating a focus lens in the lens device 100, but is not limited thereto, and may be an operation device capable of operating other members such as a zoom lens.

[0028] The D communication unit 301 is a communication unit that communicates with other communication-connected devices such as the lens apparatus 100. The D communication unit 301 transmits data input from the D calculation unit 302 to the other communication-connected devices with which it is communicatively connected, and also outputs data received from the other communication-connected devices to the D calculation unit 302. In this embodiment, the D communication unit 301 outputs at least D display data received from the lens apparatus 100 to the D calculation unit 302. The D communication unit 301 also outputs identification information input from the D calculation unit 302 to the lens apparatus 100.

[0029] The D calculation unit 302 is a control unit such as a CPU. The D calculation unit 302 outputs the D display data input from the D communication unit 301 to the D display unit 307, and outputs its own identification information to the D communication unit 301. The D calculation unit 302 also has a D display information creation unit 306, and converts the display data into display data suited to the D display unit 307 described later. The D display unit 307 is a display device, and is at least a UI that is visible to the user. The D display unit 307 displays the display data converted by the D display information creation unit 306. The display device is, but is not limited to, an LCD or an organic EL.

[0030] Next, the L-role identification unit 103 will be described with reference to Fig. 2. Fig. 2 is a block diagram of the L-role identification unit 103. The L-role identification unit 103 has a connection unit detection unit 1031, an operator identification unit 1032, and a role management unit 1033.

[0031] The connected unit detection unit 1031 detects a unit (a unit constituting the imaging system 10) connected to the lens device 100 based on the identification information acquired from the L communication unit 101. The connected unit detection unit 1031 transmits identification information of the unit (operation member) connected to the lens device 100 to the operator identification unit 1032. The identification information is information for identifying "what" operation member the lens device 100 is connected to. For example, if the identification information is information indicating the camera device 200, it is a camera device, and if the identification information is information indicating the operation device 300, it is an operation device. Details of the identification information will be described later with reference to FIG. 7. The L role identification unit 103 may hold identification information of various information holding devices, identify the type of the connected information holding device based on information on the terminal voltage between the devices and information on communication, and identify the identification information from the identified type of the information holding device.

[0032] The operator identification unit 1032 uses a role table described later to identify the positional relationship between the operation device 300 and the lens device 100 from the connected operation members (units). For example, it is determined that an operation member located close to the lens device 100 is operated by one operator, and an operation member located remotely is operated by an operator other than the operator located near the lens device 100. As described above, a group of operators and operation members is identified, and the operation members, locations, and operators are registered in role information. In addition, the role information is transmitted to the role management unit 1033. The role table is stored in a non-volatile memory (not shown), and can be referenced from anywhere in the role specification unit 103. Details will be described later with reference to Figs. 8(a) to (c), but the role table is a list of information holding devices to which the connected unit detection unit 1031 may be connected in advance. In addition, the role table indicates, for each information holding device, information on the positional relationship with respect to the lens device and information indicating the role of the person operating the information holding device in shooting.

[0033] The role management unit 1033 identifies the role of the operator from the function of the operating member by using a role table described later. For example, when a zoom demand or focus demand is connected, the role of the operator is set to be angle of view adjustment or focus adjustment. The identified role is registered in role information. The registered role information is also transmitted to the L display content determination unit 105.

[0034] Next, the role identification process performed by the L role identification unit 103 in this embodiment will be described with reference to Fig. 3. Fig. 3 is a flowchart showing the role identification process. First, after the lens device 100 is powered on, when the lens device 100 is connected to the camera device 200 or the operation device 300 for communication, the process proceeds to step S101. Hereinafter, the case where the lens device 100 is connected to the operation device 300 for communication will be described.

[0035] First, in step S101, the connection unit detection unit 1031 determines whether or not identification information has been received from the communication connection partner (operation device 300). If identification information has been received, the process proceeds to step S102. On the other hand, if identification information has not been received, that is, if the communication connection partner does not hold identification information, the process ends.

[0036] In step S102, the connected unit detection unit 1031 registers the operating member in role information based on the identification information, and transmits the role information to the operator identification unit 1032. The role management unit 1033 identifies the role of the operator based on the information registered in the role information by the connected unit detection unit 1031 or the operator identification unit 1032.

[0037] Next, in step S103, the operator identification unit 1032 judges whether or not the location of the communication connection partner (operation device 300) has been identified. If it is judged that the location of the communication connection partner has been identified, the process proceeds to step S104. On the other hand, if it is judged that the location of the communication connection partner cannot be identified, the process ends. The location is, for example, the distance between the lens device 100 and the communication connection partner, and the connection form such as wired or wireless. However, this embodiment is not limited to this, and it is sufficient that the information indicates the positional relationship with the lens device 100 in the imaging system 10. The location is specified using a role table that indicates the relationship between the operation member, the location, and the role. Details of this specification method will be described later with reference to Figs. 8(a) to (c). Note that if there is no connected operation member in the role table, the role cannot be specified, and the process ends.

[0038] In step S104, the operator identification unit 1032 registers the location in the role information, and transmits the role information in which the location is registered to the role management unit 1033. Next, in step S105, the role management unit 1033 identifies the role of the operator based on the operating member and the location (information regarding the operator's operation). Details of the identified role will be described later with reference to FIG. 7, but an example of the role is "angle of view adjustment." Next, in step S106, the role management unit 1033 registers the role identified in step S105 in the role information, and ends this process. Note that a similar process can also be performed on the camera device 200.

[0039] Next, the display specification process performed by the L display specification unit 104 in this embodiment will be described with reference to Fig. 4. Fig. 4 is a flowchart showing the display specification process. First, after the lens device 100 is powered on and connected for communication with the camera device 200 or the operation device 300, the process proceeds to step S201. Hereinafter, the case where the lens device 100 is connected for communication with the camera device 200 will be described.

[0040] First, in step S201, the L display specification unit 104 judges whether or not identification information has been input from the communication connection partner (camera device 200) (whether or not identification information has been received). If it is judged that identification information has been input, the process proceeds to step S202. On the other hand, if it is judged that identification information has not been input, step S201 is repeated. The identification information is information about the camera device if it is the camera device 200, and information about the operation device if it is the operation device 300, and includes information that can identify a display unit that can be used by the lens device 100 and information that can specify the display format or display range of the display unit. Specifically, as will be described later, for example, the "operation member", "presence or absence of a display unit", "display format", or "display range" shown in FIG. 7 is information that can identify the display capability of the display unit (information about the display capability of the display unit, for example, information about the display range of the display unit). However, in this embodiment, the identification information is not limited to these, and may be other information.

[0041] In step S202, the L display identification unit 104 determines whether or not the communication connection partner (camera device 200) has a display unit from the identification information, and registers the result in the identified display unit information. If it is possible to determine from the identification information that a display unit is present, the determination is made from the identification information, and if not, the determination may be made from pre-set conditions or settings. The identified display unit information includes information (parameters) on the type, display format, or display capabilities of the identified display unit. More specifically, as will be described later, there are, for example, "display unit," "display format," or "display range" shown in FIG. 10(b), which are information that can identify the location and display capabilities of the display unit, but are not limited to these.

[0042] Next, in step S203, the L display specification unit 104 specifies the display format and display capabilities of the display unit of the communication connection partner (camera device 200) from the identification information, and registers it in the specified display unit information (specifies the display unit from a correspondence table between parameters and display units).Then, the L display specification unit 104 outputs the specified display unit information to the L display content determination unit 105, and ends this process. Note that the same process can be performed for the operation device 300.

[0043] Next, the display content determination process (display target determination process) performed by the L display content determination unit 105 in this embodiment will be described with reference to Fig. 5. Fig. 5 is a flowchart showing the display content determination process (display target determination process). Hereinafter, a case where the contents of the C display data to be transmitted to the camera device 200 are determined will be described.

[0044] First, in step S301, the L display content determination unit 105 determines whether or not specific display unit information has been input. If specific display unit information has been input, the process proceeds to step S302. On the other hand, if specific display unit information has not been input, step S301 is repeated.

[0045] In step S302, the L display content determination unit 105 determines whether role information has been input. If it is determined that role information has been input, the process proceeds to step S303. On the other hand, if it is determined that role information has not been input, the process proceeds to step S304. In step S303, the L display content determination unit 105 determines display item candidates based on a correspondence table between role information and display items. Note that a method of determining display item candidates based on role information will be described later. In step S304, the L display content determination unit 105 determines display item candidates based on a correspondence table between specific display unit information and display items (for example, a table that associates information related to the display capacity of the display unit with the contents of display data). Note that a method of determining display item candidates based on specific display unit information will be described later.

[0046] In step S305, the L display content determination unit 105 determines and creates the display content SInfo_c based on the display item candidates and the specific display unit information. The method of determining the display content based on the display item candidates and the specific display unit information will be described later. The display content SInfo_c is information that represents the display content for the camera device 200 in this embodiment.

[0047] Next, in step S306, the L display content determination unit 105 performs a display target determination process to determine and generate a display target St_c that displays the display content SInfo_c. In the display target determination process, the L display content determination unit 105 refers to the specific display unit information and determines the display target St_c according to the information holding device ID. The display target St_c is information indicating that the camera device 200 in this embodiment is to be the display target. Next, in step S307, the L display content determination unit 105 outputs the display content SInfo_c and the display target St_c, and ends this process.

[0048] For the operation device 300, the process is performed in the flow of steps S301 to S304 described above. However, in step S305, the display content SInfo_d is determined, and in step S306, the display target St_d is determined. For example, the display information SInfo_d created for the operation device 300 may be different from or the same as the display information SInfo_d created for the camera device 200.

[0049] Next, the display information creation process performed by the L display information creation unit 106 in this embodiment will be described with reference to Fig. 6. Fig. 6 is a flowchart showing the display information creation process. Hereinafter, a case where C display data to be transmitted to the camera device 200 is created will be described. When a display information creation request is made to the L display information creation unit 106 after the display content determination process in Fig. 5 is completed, this process starts and proceeds to step S401.

[0050] First, in step S401, the L display information creation unit 106 determines whether the display content SInfo_c determined in the display content determination process has been input. If it is determined that the display content SInfo_c has been input, the process proceeds to step S402. On the other hand, if it is determined that the display content SInfo_c has not been input, step S401 is repeated.

[0051] In step S402, the L display information creation unit 106 judges whether or not the display object St_c determined in the display content determination process has been input. If it is judged that the display object St_c has been input, the process proceeds to step S403. On the other hand, if it is judged that the display object St_c has not been input, the process repeats step S402.

[0052] In step S403, the L display information creation unit 106 creates C display data by converting data into a format that can be displayed on the display object St_c based on the display content SInfo_c acquired in step S401 and the display object St_c acquired in step S402. Specifically, it is possible to know what data the display unit of the destination requires using the information of the display object St_c from the information of the display device stored in the storage unit (not shown). It is possible to know from the display object St_C that it is the camera device 200, and it is possible to know from the camera device 200 that the display unit can display by inputting ASCII data. Note that, although ASCII data is used in this embodiment, it is not limited to this. For example, if it is the same display device as the lens device 100, it may be converted into output data that matches the display device. When information on the number of display pixels can be acquired, it may be configured to output information such as on / off for each display pixel. It is also possible to transmit and receive information that can identify the display data as identification information, include it in the display identification information in the display identification unit, and use it in the display information creation process to convert the display data.

[0053] Next, in step S404, the L display information creation unit 106 outputs the C display data created in step S403 to the L communication unit 101, and this process ends.

[0054] For the operation device 300, processing is performed in the flow of steps S401 to S404 described above. However, in step S403, D display data is created, and in step S404, the D display data is output to the L communication unit 101. In the camera device 200, the C display data received from the lens device 100 is displayed on the C display unit 207. Also, in the operation device 300, the D display data received from the lens device 100 is displayed on the D display unit 307. The actual display by this processing will be described later with reference to FIG.

[0055] Next, the identification information will be described in detail with reference to Fig. 7. Fig. 7 is an example of the identification information. Fig. 7 is an example of the identification information. In Fig. 7, information in columns (A) to (E) indicate examples of the identification information held by the information holding device.

[0056] Column (A) is an identifier for identifying a device as a unique information holding device. Column (B) indicates an operation member connected to the imaging system 10. Column (C) indicates the presence or absence of a display unit. "Yes" indicates that the information holding device has a display unit, and "No" indicates that the information holding device does not have a display unit. Column (D) indicates the display format when the user device uses the display unit. "Occupied" indicates that the entire display screen of the display unit can be occupied, and "Overlapped" indicates that a part of the display screen of the display unit can be used. Column (E) indicates the display range of the display unit that can be used. For example, "96 dots vertical / 384 dots horizontal" indicates that the vertical and horizontal sizes of the screen are in units of dots, and "16 characters / 2 lines" indicates that two lines of 16 characters can be displayed per line. For example, if identification information can be obtained by communication from an information holding device called zoom demand A, it can be known that the device has an operation member called a zoom operation device (wired), and this can be used for role identification in the role identification process described later. Furthermore, columns (C) to (E) indicate the presence or absence of a display unit and its display performance, which can be used to identify the display unit in the display identification process described below.

[0057] Next, an example of the role identification process in this embodiment will be described with reference to Fig. 8(a) to (c). Fig. 8(a) is an example of a role table, and Fig. 8(b) is an example of role information. The role identification process is a process performed by the L role identification unit 103 to identify the role of the operator who operates the operating member.

[0058] First, the role table shown in FIG. 8(a) will be described. The role table is a table for identifying the role of an operator from an operation member. Column (A) in FIG. 8(a) represents the operation members connected to the imaging system 10. Column (B) in FIG. 8(a) represents the location from the lens device 100. Those connected to the lens device 100 by wire are located close to the lens, and those connected wirelessly are located remotely. As for the VE remote control, it is assumed that the focus and brightness of the lens are adjusted from a position away from the lens device 100, and it is located remotely. In this embodiment, a method of determining the location in advance in association with the operation member will be described as an example, but a method of automatically identifying the location of the operation member using GPS or the like, or a method of the user setting using a setting means (not shown) may also be used. In this embodiment, there are two types of locations, close to the lens and far from the lens, but multiple types of locations may be defined for the purpose of identifying the number of operators and their respective locations.

[0059] Next, the roles in column (C) in Fig. 8(a) will be explained. Shooting is performed by various people with their own roles, such as the cameraman who drives the lens to adjust the angle of view and focus, and the VE who moves the focus to fine-tune the focus. Column (C) in Fig. 8(a) shows the roles of operators that can be considered from the functions of the operating members used in shooting. Roles are not limited to these and may differ depending on the shooting mode, so the user may be able to register them.

[0060] Next, the role identification process will be described using the role information shown in FIG. 8(b). Here, the role identification process will be described for the case where a camera L1, a lens, a zoom operation device (wired) D1, and a VE remote control D2 are connected to the imaging system 10 as shown in FIG. 8(c), and operators P1 and P2 are present. The role information is information about the role of the operator identified from the connection unit. First, the camera, lens, zoom operation device (wired), and VE remote control connected to the operation members of the role information are registered. In this case, referring to column (B) in FIG. 8(a), it is identified that the camera, lens, and zoom operation device (wired) are located near the lens, and the VE remote control is located far from the lens. The lens near and lens far are registered in the location of the role information.

[0061] Next, column (C) in FIG. 8(a) is referenced, and the role corresponding to the operating member is registered in the role information. Next, the location of the registered role information in FIG. 8(b) is referenced, and it can be specified that one operator (operator A) is located close to the lens, and another operator (operator B) is located far from the lens. Operator A and operator B are registered as operators in the role information. Therefore, by performing the role identification process described above, the roles of the operators can be identified.

[0062] Next, the determination of display item candidates using a correspondence table between role information and corresponding items will be described with reference to Fig. 9. Fig. 9 shows an example of roles and display item candidates, and shows a correspondence table for determining optimal display item candidates for an operator who plays a role based on the role in the role information. This is intended to determine optimal display item candidates for the role of the operator included in the role information.

[0063] Column (A) shows the role that the operator plays, and column (B) shows candidate display items that correspond to column (A). For example, if the role is angle of view adjustment, the candidate display items can be determined to be zoom position and zoom command value from the correspondence table. For example, if the role is focus adjustment, the candidate display items will be information related to the focus adjustment of the system, such as focus position and focus command value, and depth of field. If the role is brightness adjustment, the candidate display items will be information related to the brightness of the system, such as iris position and iris command value, camera gain, exposure time, and filter setting.

[0064] The correspondence table between the role information and the corresponding items may be stored in advance in a storage unit (not shown), or may be changeable by providing a changing means (not shown). For example, a display unit and an operation unit (not shown) may be provided so that the user can directly edit the correspondence table.

[0065] Next, an example of the display specification process in this embodiment will be described with reference to Figs. 10(a) and (b). The display specification process is intended to specify the display unit of the information holding device from the information related to the display unit among the identification information acquired from the information holding device, and to create the specified display unit information used in the display content determination process. Fig. 10(a) is a correspondence table for specifying the display unit from a part of the identification information described with reference to Fig. 7. Columns (A) to (D) in Fig. 10(a) are the same as columns (B) to (E) in Fig. 7, respectively. Column (E) shows the type of the display unit specified from the information in columns (A) to (D). Fig. 10(b) is an example of the specified display unit information specified by the display specification process. Column (A) in Fig. 10(b) shows the type of the display unit specified by the display specification process. Columns (B) and (C) in Fig. 10(b) are the same as columns (D) and (E) in Fig. 7, respectively. Column (D) in Fig. 10(b) is the same as column (A) in Fig. 7. These are acquired as information related to display performance from the identification information in the display specification process.

[0066] Next, an example of the display specification process of the L display specification unit 104 when a camera, a lens, a zoom operation device (wired), and a VE remote control are connected to the imaging system 10 will be described. First, identification information is acquired, and a matching combination of operation members, presence or absence of a display unit, display format, and display range included therein is specified by referring to columns (A) to (D) in FIG. 10(a). Next, the display unit is specified by referring to column (E) of the specified combination. For example, if the acquired identification information is a combination of lens, presence of display unit, occupied, and 96 dots vertical / 384 dots horizontal, it is found that the matching columns (A) to (D) are the (1st) row in FIG. 10(a). Therefore, the display unit can be specified from column (E) of the correspondence table, "external lens display". Next, the specified display unit information shown in FIG. 10(b) is created from the specified display unit and information related to the display performance included in the identification information.

[0067] As described above, the correspondence table can be used to identify a display unit from the identification information of a connected device, and specific display unit information can be created by adding information related to the display performance of the identification information. By creating the specific display unit information in this manner, the lens device 100 of this embodiment can determine display item candidates and display content using the specific display unit information described later.

[0068] Next, a process of determining display item candidates using the specified display unit information and the correspondence table of corresponding items will be described with reference to Fig. 11. The purpose of the process of determining display item candidates is to determine suitable (preferably optimal) display item candidates for each specified display unit included in the specified display unit information. Fig. 11 is a correspondence table for determining optimal display item candidates for a display unit from the display unit items included in the specified display unit information.

[0069] In Fig. 11, column (A) indicates the identified display unit, and column (B) indicates the display item candidates corresponding to column (A). For example, if the display unit is an "external lens display", a matching row is searched for among rows (1) to (5) of the display unit in column A of the correspondence table, and it is found to match row (1). By referring to the corresponding display item candidates (B), the display item candidates can be determined to be "error message", "zoom position", "focus position", "iris position", and "zoom speed".

[0070] The correspondence table between the specific display unit information and the corresponding items may be stored in advance in a storage unit (not shown), or may be changeable by providing a changing means (not shown). For example, a display unit and an operation unit (not shown) may be provided so that the user can directly edit the correspondence table.

[0071] Next, a process of determining display contents based on display item candidates and specific display unit information will be described with reference to Fig. 12. The process of determining display contents includes a display item determination process that selects items to be actually displayed from display item candidates based on the specific display unit information in accordance with the display format or display capacity of the display unit. Also, a display configuration determination process that determines where on the screen of the display unit the display items are to be displayed in accordance with the display format or display capacity of the display unit.

[0072] FIG. 12 is an example of display content determined from display item candidates and display performance. Column (A) shows display item candidates determined by display content determination unit 105. Columns (B) and (C) are similar to columns (D) and (E) in FIG. 7, respectively. Column (D) shows display items determined by the display content determination process from the display item candidates. Column (E) shows the display configuration determined according to the display format and display capabilities of the display unit. Column (F) is similar to column (A) in FIG. 7.

[0073] 12, (1) to (3) indicate cases where the display contents are determined from different display unit information. For example, line (1) is information when the display contents are determined from the display unit information of L display unit 107 provided in lens device 100. Line (2) corresponds to C display unit 207 provided in camera device 200, and line (3) corresponds to D display unit 307 provided in operation device 300 serving as a demand device.

[0074] Here, we will provide additional information about the notation in columns (A) and (D) of line (1). The notation in the table is actually expressed as the item name to be displayed as written in lines (2) and (3), but to make the explanation easier to understand, we have deliberately used the character string that is actually displayed on the display unit. For example, in lines (2) and (3), "Err00" is displayed where "Error message" should be displayed. The following explanation will be given using the contents of line (1) as an example.

[0075] The display item candidate "Err00" in column (A) in FIG. 12 corresponds to the "error message" in the other rows, and indicates whether or not there is an error in the information storage device. "Err00" indicates that there is no error in the imaging system 10 of this embodiment. Next, "IrisFol:2.8" corresponds to the "iris position" and indicates how wide the iris of the imaging system 10 is open. "ZoomFol:150" corresponds to the "zoom position" and indicates how many mm the angle of view of the imaging system 10 is. "FocusFol:300" corresponds to the "focus position" and indicates how many meters the subject distance of the imaging system 10 is. "ZoomSp:80" corresponds to the "zoom speed" and indicates how many percent of maximum the zoom change speed of the imaging system 10 is.

[0076] First, the determination of display items will be explained. The display item candidates in column (A) in FIG. 12 are determined by the method described with reference to FIG. 11. When a display device has a display range, there is a limit to the display items that can be displayed. Therefore, the number of characters required to display the display item candidates and the displayable display items are determined from the displayable range. Generally, a display device expresses the horizontal and vertical display range in dots (also called pixels), and an image is expressed by turning on / off one dot. The following explains the example of row (1). For example, the display item candidate "Error message" is actually displayed as five characters, "Err00". One character is 20x20 [dots], and if spaces are provided between each character, it can be displayed as 21x21 [dots]. Therefore, it is understood that 5 characters x 21x21dots = 105x105dots are required. Next, if the display range is 96dots vertically and 384dots horizontally, the vertical is 96÷21≒4, and it can be determined that 4 characters can be displayed vertically. The width is 384÷21≒18, so it can be determined that 18 characters can be displayed horizontally.

[0077] As a result of these, if one item is simply displayed per line on a display area that can display 4 characters vertically and 18 characters horizontally, it is clear that only 4 of the 5 candidate display items can be displayed. In this way, the display range information can be used to adjust the items from the candidate display items to the number of items that can be displayed, and the display items can be determined.

[0078] Next, the determination of the display configuration will be described. The display configuration may be any way in which the determined display items are displayed within the display range, but in this embodiment, it is determined so that one item is listed per line from the top of the display item candidates, as in the first line of FIG. 13(b). Also, if there are items and values ​​corresponding to the items, they may be displayed in separate columns, as in the fourth line of FIG. 13(b). In this way, the determined contents of how the determined display items are displayed on the display unit are shown in the display configuration in column (E) in FIG. 12. However, as for the type of display configuration, the determined display items may be enlarged to fill the screen, or the items may simply be displayed consecutively from the top of the screen. The contents described in this section are merely examples and are not limited.

[0079] With the above configuration, it is possible to determine display items from the display range based on the specific display unit information and from the corresponding item candidates, and to determine how the display items are to be displayed in the display range.

[0080] Next, an example of a UI displayed on the external UI of this embodiment will be described with reference to Figs. 13(a) and 13(b). Fig. 13(a) shows an example of the C display unit 207, and Fig. 13(b) shows an example of the D display unit 307. The dotted lines in Fig. 13(a) show C display data, and the dotted lines in Fig. 13(b) show D display data, which are added for the purpose of illustrating the figure and are not actually displayed. In this embodiment, the information within the dotted lines is added as shown. The C display data displays information necessary for "focus adjustment", "angle of view adjustment", and "brightness adjustment", and as an example, zoom speed information and subject distance are used. In addition, the display data is limited to two lines so as not to interfere with the confirmation of the image display. The D display data displays information necessary for the "focus operator", and as an example, focus position information and focus operation right information are used.

[0081] With the above configuration, the role and display unit of the device connected for communication can be identified, and the content to be displayed on the external UI can be determined based on the identified information, so that the display of the external UI always becomes information necessary for the person viewing the UI. Even if the display capability of the display unit of the operation device 300 is changed, if the information of the display unit can be identified, the display of the external UI can be changed according to the display capability. By performing the above processing, it becomes possible to display information according to the role and display unit of the device connected for communication on the external UI.

[0082] In this embodiment, the role information is shown in Fig. 8, but it is merely an example and is not limited thereto. In addition, the display information is identification information such as the presence or absence of a display unit and display capabilities, but is not limited thereto. For example, it may be information such as whether or not transmission and reception of C display data is supported, or it may be setting information for the display unit of each device. By being able to acquire setting information for the display unit, display may be possible depending on the settings, but it is possible to change the display information output from the lens device 100 depending on whether or not it is actually displayed.

[0083] In addition, in the display content determination process, communication information with the communication connection partner is monitored, and information that is not actually communicated is set as the display content, but this is not limited to this. For example, information on an abnormal state or the like is information that the user should be aware of even if it is duplicated, and the display content may be determined taking into account the above-mentioned display settings.

[0084] In addition, the role and the display unit are automatically determined based on information acquired from each device, but are not limited thereto. For example, the operator may directly set the role. Also, the role may be specified in relation to the lens setting contents of the operator (based on information on the unit setting by the operator). For example, when the focus driving range is limited, the role may be focus adjustment. In addition, the role and the display unit itself may be settable, and the priority order for determining the display contents may be settable. In this embodiment, the role is specified from the functions of all the connected operating members, but the role may be specified as one from the operating state of the operating members. For example, when a state in which the zoom demand is operated is detected as the operating state, the role is angle of view adjustment.

[0085] In addition, in this embodiment, the start trigger of the role specification process, the display specification process, the display content determination process, and the display information creation process is a communication connection with another communication connection device, but this is not limited to this. For example, the trigger may be a switch operation in the imaging system 10, and all of these processes do not have to be performed in conjunction with each other. In addition, the display of the C display data is always displayed, but this is not limited to this. For example, it may be displayed only when a switch to which an additional information display function is assigned is operated.

[0086] Furthermore, the display information created in the display information creation process is primarily output to an external UI, but may also be output to the L display unit 107 included in the device itself. In this embodiment, the role specification process, the display specification process, the display content determination process, and the display information creation process are executed by the lens device 100, but are not limited to this. At least a part of each process may be executed by the camera device 200 or the operation device 300, for example.

[0087] According to this embodiment, it is possible to display necessary information in an optimal location for the photographer, depending on the role of the photographer and the specified display unit. EXAMPLES

[0088] Next, a second embodiment of the present invention will be described. In the first embodiment, the display contents are determined only by the type of the display unit specified in the display specification process. However, it may not be appropriate for the operator to display the same information in a limited display range in an overlapping manner. In addition, when displaying by superimposing on an image, if the existing display configuration is ignored, data of different natures may be displayed side by side, making the display difficult to see. Therefore, in this embodiment, an example in which the display contents of a display unit are created based on the display contents of another display unit that have already been created, so that the display contents do not overlap, will be described. In addition, the display contents to be superimposed are determined by using the existing display configuration and taking the existing display into consideration.

[0089] The basic configuration of the imaging system in this embodiment is similar to that of the imaging system 10 in the embodiment 1 described with reference to Fig. 1, and therefore a description of the configuration and operation common to the embodiment 1 will be omitted. In this embodiment, the L display specification unit 104 creates the specified display unit information shown in Fig. 15 by using the identification information to which the configuration information of the existing display is added, as shown in Fig. 14. In addition, the L display content determination unit 105 first determines the display content (contents of the display data) to be displayed on the operation device 300, and then determines the display content to be displayed on the camera device 200 so as not to overlap with the display content of the operation device 300.

[0090] The L display specification unit 104 performs a display specification process for specifying display information by adding an existing display configuration to the identification information of each device input from the L communication unit 101 in the configuration of the first embodiment. Note that detailed processing of the display specification process using the existing display configuration will be described later. The L display content determination unit 105 performs a display content determination process for determining the display content of another device (e.g., the camera device 200) by referring to the display content of a certain device (e.g., the operation device (demand device) 300) that has already been determined in the first embodiment. Note that detailed processing flow of the display content determination process of another device based on the display content of a certain device that has already been determined will be described later.

[0091] Next, the identification information will be described in detail with reference to Fig. 14 and Fig. 15. Fig. 14 is an example of the identification information possessed by the information holding device. Columns (A) to (E) in Fig. 14 are similar to columns (A) to (E) in Fig. 7, respectively. Column (F) in Fig. 14 shows the display content (existing display configuration) originally displayed on the display unit of the information holding device.

[0092] FIG. 15 is a diagram showing the display contents of a display unit in a certain information holding device (one example of an existing display configuration). A central rectangle 1600 indicates the display screen of the display unit, and outer lines 1601 and 1602 indicate the size of the display screen. This indicates in coordinates that the entire display range is 0 to 4000 horizontally and 0 to 3000 vertically. A rectangle 1603 indicates a zoom relative position, indicating that the start coordinates of the display position are (0,0) and the end coordinates are (21,80). A rectangle 1604 indicates a focus relative position, indicating that the start coordinates of the display position are (0,3920) and the end coordinates are (21,4000). A rectangle 1605 indicates an aperture position, indicating that the start coordinates of the display position are (2979,3920) and the end coordinates are (3000,4000).

[0093] Here, each item of the existing display configuration (F) in the third row of FIG. 14 will be described in detail. "Display range when occupied: 4000 horizontal, 3000 vertical" indicates the entire display range of the display unit of the information holding device (A), and corresponds to the rectangle 1600 in FIG. 15. "Zoom relative position: {(0,0),(21,80)}" corresponds to the rectangle 1603. "Focus relative position: {21,3920),(21,3000)}" and "Aperture position: {(3994,2984),(4000,3000)}" also correspond to the rectangle 1604 and the rectangle 1605, respectively. In other words, each item of the existing display configuration (F) represents the contents displayed on the display unit of a certain information holding device. In this way, if the existing display configuration (F) is known, the original display contents displayed on the display unit of the information holding device (A) can be known.

[0094] Next, an example of the display specification process in this embodiment will be described with reference to Figures 16(a) and 16(b). In this embodiment, by using identification information including the existing display configuration, specific display unit information is created for specifying which information is displayed at which position on the display screen as the existing display configuration in each display device detected by the lens device.

[0095] FIG. 16(a) is a correspondence table (display unit identification table) for identifying a display unit from a part of the identification information described with reference to FIG. 14. The existing display configuration described with reference to FIG. 14 is added to FIG. 10(a). Columns (A) to (E) of FIG. 16(a) are similar to columns (B) to (F) of FIG. 14, respectively. Column (F) of FIG. 16(a) indicates the type of display unit identified from the information of columns (A) to (E). FIG. 16(b) is an example of identified display unit information identified by a display identification process. Column (A) of FIG. 16(b) indicates the type of display unit identified by the display identification process. Columns (B) and (C) of FIG. 16(b) are similar to columns (D) and (E) of FIG. 14, respectively, and are obtained as information related to display performance from the identification information in the display identification process.

[0096] Next, an example of the display specification process of the L display specification unit 104 when a camera, a lens, a zoom operation device (wired), and a VE remote control are connected to the imaging system 10 will be described. First, the L display specification unit 104 acquires the identification information, and identifies a matching combination of the operation member (A), the presence or absence of a display unit (B), the display format (C), the display range (D), and the existing display configuration (E) contained therein by referring to columns (A) to (E) in FIG. 16(a). Next, the L display specification unit 104 identifies the display unit by referring to column (F) of the identified combination. For example, if the acquired identification information is a combination of a tele-wide switch, the presence of a display unit, superimposition, and 50 dots vertically / 1000 dots horizontally, it is found that the matching columns (A) to (E) are the (3)th row in FIG. 16(a). Therefore, the display unit can be identified from "camera VF" in column F of the correspondence table. In this way, by collecting some of the information specified from the identification information, it is possible to create specific display unit information relating to a certain display unit and its performance, as shown in FIG. 16(b).

[0097] As described above, by using the correspondence table to identify the display unit from the identification information of the connected device and compiling information related to the display performance, it is possible to identify specific display unit information including the existing display configuration.

[0098] Next, with reference to Fig. 17, a description will be given of how to determine display content items from display item candidates, specific display unit information, and previously determined display content of another display device. In this embodiment, when determining display items to be actually displayed from display item candidates, display content already determined for another device is taken into consideration. For example, if the display content of the operation device (demand device) 300 has already been determined, when determining the display items of the camera device 200, the display items are determined from the display content of the operation device 300 so as not to overlap the display contents of both.

[0099] FIG. 17 shows an example of display content items determined from the display content of another device, and shows information necessary for determining the display items. Column (A) in FIG. 17 shows display item candidates determined by the L display content determination unit 105. Columns (B) and (C) in FIG. 17 are similar to columns (D) and (E) in FIG. 14, respectively. Column (D) in FIG. 17 is a display item of another display unit that has already been determined. Column (E) in FIG. 17 shows a display item determined by the display content determination process from the display item candidates by determining that among the items in column (A), they are not included in column (D). Column (F) in FIG. 17 is similar to column (A) in FIG. 14.

[0100] The following description will be given by taking the contents of line (1) in FIG. 17 as an example. First, the determination of the display item will be described. The display item candidate (A) is determined by the method described with reference to FIGS. 16(a) and 16(b). In this embodiment, the display range (C) is "16 characters / 1 line". This indicates that there is a display range of 16 characters for one line. Therefore, for the three items of the determined display item candidate (A), if the display range is limited to 16 characters and one line, and only one item can be displayed per line, all of the display item candidates cannot be displayed. Next, by comparing the display item candidate (A) with the four items of the display items (D) of the other device, it is found that the display item that has not yet been displayed is "zoom speed". Based on this information, the display item that exists in column (A) but does not exist in column (D) can be determined to be "zoom speed" shown in column (E).

[0101] Next, the determination of the display configuration using the determined display items and the existing display configuration will be described with reference to Fig. 18. In this embodiment, when determining the configuration of the display contents, the display configuration is determined so as to bring the existing display and related information closer together by newly taking into account the existing display configuration. For example, when determining the display configuration for superimposing and displaying information on the camera device 200, the display configuration is determined so as to superimpose the display in a nearby location based on the existing display already displayed on the camera device 200.

[0102] Fig. 18 is an example of a display content configuration determined from an existing display configuration, and shows a screen when the determined display item zoom speed is configured near an existing zoom-related display for the existing display configuration of the camera VF, which is the display unit in Fig. 16(b). By referring to the "zoom relative position {(0,0),(21,80)}" included in the existing display configuration, it is found that zoom-related information is located at the position of rectangle 1901 shown in Fig. 18. Based on this information, the display item "zoom speed", which is the same zoom-related information, can be located at the position of rectangle 1902. With this configuration, it is possible to determine a display content configuration that displays related display items using the existing display configuration.

[0103] Next, an example of a UI displayed on the external UI of this embodiment will be described with reference to Figs. 19(a) and 19(b). Fig. 19(a) shows an example of the C display unit 207, and Fig. 19(b) shows an example of the D display unit 307. The dotted lines in Fig. 19(a) show the C display data, and the dotted lines in Fig. 19(b) show the D display data, which are added for the purpose of illustrating the figures and are not actually displayed. In this embodiment, the information within the dotted lines is added as shown. The C display data determines the display items based on the D display data so that there is no overlap, and further uses the existing display configuration of the identification information to display the display contents so that the configuration of related data is brought closer. As a result, the display is good for the operator checking the display.

[0104] In this embodiment, an example has been described in which the role identification unit, display identification unit, display content determination unit, and display information creation unit are provided in the lens device 100, but this is not limited to the above, and at least one of each unit may be provided in the camera device 200 or the operation device 300.
