Description

【Technical Field】 【0001】 The present invention relates to a control device, a control method, and a program. 【Background Art】 【0002】 In recent years, for example, in video production, video editing and distribution systems using an IP (Internet Protocol) network such as the Internet have been increasing. In a general system, a video editing device such as a switcher receives a video stream such as video and audio output from a camera connected to an IP network, edits it as broadcast video as needed, and then performs distribution / output. In addition, cameras used in such systems are not only of the type that is held and photographed by a person, but also of the type that performs pan-tilt-zoom control remotely via an application installed on a controller or a PC. Furthermore, some of these cameras have a preset function for registering conditions such as the position of the camera's pan-tilt-zoom and image quality settings before imaging (before shooting) as preset settings. In addition, some controllers for operating the camera have a function of collectively switching the preset settings used for each imaging (shooting) scene by treating a plurality of preset settings as one preset group. 【0003】 Patent Document 1 describes a technique for restricting the movable range of a camera (imaging unit) with respect to a range where reflection is to be avoided during preset imaging. 【Prior Art Documents】 【Patent Documents】 【0004】 【Patent Document 1】 Japanese Patent Application Laid-Open No. 2002-359770 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0005】 However, in the technology described in Patent Document 1, for example, if the range in which reflections should be avoided during preset imaging is changed, the movable range of the camera (imaging unit) does not switch in conjunction, resulting in insufficient correspondence between the preset range and the camera's movable range. Here, the camera's movable range is assumed to be a concept included in the control range related to imaging of the imaging unit. In other words, in the technology described in Patent Document 1, there is a problem in that the correspondence between the preset information regarding the field of view of the imaging unit and the information regarding the control range setting for imaging of the imaging unit is insufficient, so when the information of one is changed, the information of the other is not appropriate. 【0006】 This invention has been made in view of the above problems, and aims to enable the setting of appropriate information for the other when one of the preset information regarding the field of view of the imaging unit or the control range setting information regarding imaging of the imaging unit is changed. [Means for solving the problem] 【0007】 The control device of the present invention includes a first acquisition means for acquiring preset information which includes at least information relating to the field of view of the imaging unit; a second acquisition means for acquiring information relating to the control range setting for imaging by the imaging unit; and a recording control means for performing control to record the corresponding preset information and the control range setting information in a recording unit. [Effects of the Invention] 【0008】 According to the present invention, when one of the preset information regarding the field of view of the imaging unit or the information regarding the control range setting for imaging of the imaging unit is changed, appropriate information can be set for the other.

Note that the embodiments described below are merely examples and do not limit the scope of the claims. Also, not all combinations of the features described in the embodiments are essential as means for solving the problems in the present invention. Further, in the embodiments described below, "video" is not necessarily limited to moving images and may be still images. 【0011】 (First Embodiment) First, the first embodiment will be described. 【0012】 FIG. 1 is a diagram showing an example of the schematic configuration of an imaging control system 10 according to the first embodiment. As shown in FIG. 1, the imaging control system 10 includes an imaging device 100, a client device 200, and a network 300. 【0013】 The imaging device 100 is a device that captures images of a subject and is configured to be communicable with a client device 200 via a network 300. The imaging device 100 includes a system control unit 101, an imaging unit 102, an image processing unit 103, a lens driving unit 104, a zoom control unit 105, a focus control unit 106, a pan driving unit 107, a tilt driving unit 108, and a pan / tilt control unit 109. Further, the imaging device 100 includes a recording unit 111, a program memory 112, a video output unit 113, and a communication unit 114. Here, as an example, in the present embodiment, a control device 110 according to the present embodiment is configured from the system control unit 101, the recording unit 111, the program memory 112, the video output unit 113, and the communication unit 114. Note that in the present invention, the control device 110 is not limited to the form shown in FIG. 1. For example, the control device 110 may be configured from the components of the imaging device 100 excluding the imaging unit 102. Also, in the example shown in FIG. 1, the control device 110 is configured inside the imaging device 100, but the present invention is not limited to this form. For example, a form in which the control device 110 is configured outside the imaging device 100 as a separate body from the imaging device 100 is also included in the present invention. 【0014】 The client device 200 is, for example, a device operated by a user and is configured to be communicable with the imaging device 100 (control device 110) via the network 300. The client device 200 includes a system control unit 201, a display unit 202, an input unit 203, and a communication unit 204. 【0015】 The network 300 is a network that communicably connects the imaging device 100 and the client device 200. 【0016】 Here, the internal configuration of the imaging device 100 shown in FIG. 1 will be described below. 【0017】 The system control unit 101 controls the entire imaging device 100 and issues processing instructions to each component other than the system control unit 101 (102-109, 111-114). The system control unit 101 also analyzes camera control commands received from the client device 200 via the communication unit 114 and causes the aforementioned components to execute processing according to the camera control commands. Camera control commands include field of view control commands (including imaging direction control) that control pan, tilt, zoom, etc. of the imaging unit 102, image quality control commands that control imaging conditions such as gamma and color matrix, and request commands that request the acquisition of video data and set values. 【0018】 Furthermore, the system control unit 101 outputs the video data generated by the image processing unit 103 from the video output unit 113. Also, when the system control unit 101 receives a request command from the client device 200 requesting video data, it transmits the video data generated by the image processing unit 103 to the client device 200 via the communication unit 114. 【0019】 Furthermore, the system control unit 101 receives a request command from the client device 200 requesting information indicating the settings of the imaging device 100, such as zoom, focus, and pan / tilt. Upon receiving this request command, the system control unit 101 reads the requested settings (pan value, tilt value, zoom value) from the image processing unit 103, zoom control unit 105, focus control unit 106, and pan / tilt control unit 109, and transmits them to the client device 200. The settings for zoom, focus, pan / tilt, etc., include not only the current values ​​but also related information such as the range of values ​​that can be set on the imaging device 100. 【0020】 Furthermore, the system control unit 101 receives field-of-view control commands from the client device 200 to set or change zoom, focus, pan, and tilt. Upon receiving these field-of-view control commands, the system control unit 101 controls the image processing unit 103, zoom control unit 105, focus control unit 106, and pan / tilt control unit 109 according to the setting values ​​indicated by the field-of-view control commands. In this way, the system control unit 101 functions as a zoom control means that performs zoom control to change the zoom value in the imaging device 100 (imaging unit 102). The system control unit 101 also functions as an imaging direction control means that performs pan control to change the imaging direction in the imaging device 100 (imaging unit 102) in the pan direction, and tilt control to change the imaging direction in the tilt direction. 【0021】 Furthermore, when the system control unit 101 receives a request command from the client device 200 to change the preset group, it switches the range of preset settings that can be executed. For example, the system control unit 101 switches the range so that preset group 1 includes preset settings 1 through 10, and preset group 2 includes preset settings 11 through 20. In addition, the system control unit 101 reflects the associated movable range settings when the preset group is switched, according to the correspondence information between the preset group and the movable range setting recorded in the recording unit 111. 【0022】 Furthermore, when the system control unit 101 receives a control command from the client device 200 to set the field of view control range, it sets the control range for the zoom control unit 105 and the pan / tilt control unit 109 according to the setting value indicated in the control command. In this embodiment, the control range is the control range related to imaging by the imaging unit 102. The image processing unit 103, zoom control unit 105, focus control unit 106, and pan / tilt control unit 109 control the operation of the imaging unit 102, lens drive unit 104, pan drive unit 107, and tilt drive unit 108, respectively, in response to the control from the system control unit 101. As a result, the setting values ​​related to zoom, focus, pan, and tilt set in the client device 200 are reflected in the imaging device 100. When a control range is set, the setting values ​​related to zoom, pan, and tilt set in the client device 200 are limited to the set control range. 【0023】 Furthermore, when the system control unit 101 receives an image quality control command from the client device 200 to set gamma or other parameters, it controls the operation of the image processing unit 103 according to the setting values ​​indicated in the image quality control command. In this case, the image processing unit 103 controls the operation of the imaging unit 102 according to the control from the system control unit 101. As a result, the image quality control settings set in the client device 200 are reflected in the imaging device 100. 【0024】 The system control unit 101 also functions as a first acquisition means 115 for acquiring preset information that includes at least information regarding the field of view of the imaging unit 102. The system control unit 101 also functions as a second acquisition means 116 for acquiring information regarding the control range setting for imaging by the imaging unit 102. The system control unit 101 also functions as a recording control means 117 for recording the corresponding preset information and control range setting information in association with the recording unit 111. Furthermore, the system control unit 101 also functions as a display control means 118 for highlighting control range settings that cannot be associated with presets or control range settings that can be associated with presets. The display control means 118 also performs control to highlight presets that cannot be associated with control range settings or presets that can be associated with control range settings. 【0025】 The imaging unit 102 includes a lens and an image sensor, and performs imaging of the subject and conversion of the image into an electrical signal. 【0026】 The image processing unit 103 performs predetermined image processing, resolution conversion processing, and compression encoding processing on the electrical signals captured and photoelectrically converted by the imaging unit 102 to generate video data. The video data generated by the image processing unit 103 is output to a display device by the video output unit 113 or transmitted to a client device 200 via the network 300 by the communication unit 114. 【0027】 The lens drive unit 104 includes the drive system for the focus lens and zoom lens of the imaging unit 102, as well as a motor that serves as its drive source, and is controlled by the zoom control unit 105 and the focus control unit 106. 【0028】 The zoom control unit 105 controls the position change of the zoom lens of the lens drive unit 104 based on the zoom setting value instructed by the system control unit 101. Here, the zoom control unit 105 manages the focal length as the zoom setting value. 【0029】 The focus control unit 106 controls the position change of the focus lens of the lens drive unit 104 based on the focus setting value instructed by the system control unit 101. The focus position is changed as the position of the focus lens is changed. 【0030】 The pan drive unit 107 is equipped with a mechanical drive system and a motor that perform the panning operation of the imaging unit 102, and performs the panning operation of the imaging unit 102 in accordance with the control from the pan / tilt control unit 109. Specifically, the pan drive unit 107 can change the pan direction among the imaging directions of the imaging unit 102. 【0031】 The tilt drive unit 108 is equipped with a mechanical drive system and a motor that perform the tilt operation of the imaging unit 102, and performs the tilt operation of the imaging unit 102 in accordance with the control from the pan / tilt control unit 109. Specifically, the tilt drive unit 108 can change the pan direction of the imaging direction of the imaging unit 102. 【0032】 The pan-tilt control unit 109 controls the operation of the pan drive unit 107 and the tilt drive unit 108 based on the pan-tilt setting values ​​instructed by the system control unit 101, thereby controlling the change in the pan direction and tilt direction, which are the imaging directions of the imaging unit 102. 【0033】 The recording unit 111 records various information (including data) necessary for the system control unit 101 to perform various processes (including control), and also records various information (including data) obtained as a result of the system control unit 101 performing various processes. For example, the recording unit 111 records the settings of the imaging conditions. Also, for example, the recording unit 111 records corresponding preset information and control range setting information as association information under the control of the system control unit 101 (recording control means 117). At this time, the recording unit 111 records parameters indicating imaging conditions, such as image quality setting values, along with the field of view setting value (pan value, tilt value, or zoom value), as preset information to internal storage or external storage. In this embodiment, with respect to the preset information, the recording unit 111 records one or more preset settings as a preset group. Furthermore, in this embodiment, the recording unit 111 records information on the movable range setting, which is the range in which the pan and tilt operations of the imaging unit 102 are possible, as an example of information on setting the control range related to imaging of the imaging unit 102. 【0034】 The program memory 112 stores programs (control programs) necessary for the system control unit 101 to perform various processes (including control). 【0035】 The video output unit 113 outputs the video data generated by the image processing unit 103 to the display device. In this case, the video output unit 113 may be configured to output video data to multiple display devices. 【0036】 The communication unit 114 is a communication unit that communicates with the client device 200 via the network 300. 【0037】 Next, the internal configuration of the client device 200 shown in Figure 1 will be described below. 【0038】 The system control unit 201 generates various commands in response to user operations on the GUI (Graphical User Interface) and transmits these generated commands to the imaging device 100 (control device 110) via the communication unit 204. For example, the system control unit 201 transmits a setting command to the imaging device 100 that associates the preset groups with the movable range settings. The system control unit 201 also receives the responses of the imaging device 100 to the transmitted commands via the communication unit 204. Furthermore, the system control unit 201 controls the display unit 202 to display the video data received from the imaging device 100 via the communication unit 204. 【0039】 The display unit 202 can be configured as a display device such as an LCD projector or an LCD monitor. The display unit 202 displays images based on video data acquired from the imaging device 100, and a GUI for controlling the imaging device 100. 【0040】 The input unit 203 may include a keyboard and / or a pointing device such as a mouse or touch panel. Users of the client device 200 can operate the GUI displayed on the display unit 202 via the input unit 203. 【0041】 The communication unit 204 transmits various commands sent from the system control unit 201 to the imaging device 100 via the network 300. The communication unit 204 also receives video data transmitted from the imaging device 100, as well as the imaging device 100's responses to various commands sent from the client device 200. 【0042】 In this way, the client device 200 can perform various controls on the imaging device 100 via the network 300. 【0043】 Figure 2 is a flowchart showing an example of a processing procedure in a control method for the imaging device 100 (control device 110) according to the first embodiment, which involves recording information about preset groups and information about movable range settings in association. 【0044】 First, in step S201 in Figure 2, the system control unit 101 acquires information about the preset group currently selected by the client device 200, for example, as preset information that includes at least information about the field of view of the imaging unit 102. Specifically, the processing in step S201 is performed by the first acquisition means 115 of the system control unit 101. 【0045】 Next, in step S202 of Figure 2, the system control unit 101 acquires information on the currently selected movable range setting, for example, by the client device 200, as information on the control range setting related to imaging of the imaging unit 102. Specifically, the processing in step S202 is performed by the second acquisition means 116 of the system control unit 101. 【0046】 Next, in step S203 in Figure 2, the system control unit 101 performs control to associate the preset group information acquired in step S201 with the movable range setting information acquired in step S202 and record it as association information in the recording unit 111. Specifically, this process in step S203 is performed by the recording control means 117 of the system control unit 101. 【0047】 Once the process in step S203 in Figure 2 is completed, the process shown in the flowchart in Figure 2 is finished. 【0048】 Next, using Figures 3A to 3E, an example will be described in which the system control unit 101 records the corresponding preset group information and the movable range setting information in the recording unit 111. 【0049】 Figure 3A shows a first embodiment and is a diagram illustrating an example of a data configuration table 310 in the preset group information recorded in the recording unit 111. The data configuration table 310 shown in Figure 3A shows the preset group number (No.), the preset settings registered in each preset group, and the default preset position in each preset group. As shown in Figure 3A, each preset group has a default preset position set, and a setting is made to which preset position to move to when switching preset groups. 【0050】 Figure 3B shows a first embodiment and is a diagram illustrating an example of a data configuration table 320 in the information of the movable range setting recorded in the recording unit 111. The data configuration table 320 shown in Figure 3B shows the movable range setting number (No.) and the setting details for each movable range setting. 【0051】 Figure 3C shows a first embodiment and is a diagram illustrating an example of a data configuration table 330 when recording corresponding preset group information and movable range setting information in the recording unit 111. The data configuration table 330 shown in Figure 3C shows the number (No.) related to the association and the preset group and movable range setting assigned to each number related to the association. The data configuration table 330 shown in Figure 3C is an example of associating the preset group number with the movable range setting number, but for example, the data configuration assigned to each number related to the association may be recorded as a single scene setting. 【0052】 Figure 3D shows an example of a data configuration table 340 when recording information of a corresponding preset group and information of the range of motion settings in the recording unit 111, in accordance with the first embodiment. The data configuration table 340 shown in Figure 3D is a data configuration table in which the range of motion setting numbers are associated with the data configuration table 310 for the preset group information shown in Figure 3A. In addition, in the data configuration table 340 shown in Figure 3D, instead of associating the range of motion setting numbers, setting contents such as the coordinate information of the range of motion settings shown in Figure 3B may be associated instead. 【0053】 Figure 3E shows an example of a data configuration table 350 when recording information on corresponding preset groups and information on movable range settings in the recording unit 111, illustrating the first embodiment. The data configuration table 350 shown in Figure 3E is a data configuration table in which the preset group number is associated with the data configuration table 320 for the movable range setting information shown in Figure 3B. In addition, in the data configuration table 350 shown in Figure 3E, instead of associating the preset group number, the preset setting shown in Figure 3A may be associated instead. 【0054】 Figure 4 is a flowchart showing an example of a processing procedure in a control method for the imaging device 100 (control device 110) according to the first embodiment, which reflects (overwrites as new settings) the correspondence settings recorded in the recording unit 111. 【0055】 First, in step S401 of Figure 4, when the system control unit 101 receives a request command from, for example, the client device 200 requesting a change in the preset group settings, it changes the preset group to be set. 【0056】 Next, in step S402 of Figure 4, the system control unit 101 refers to the aforementioned correspondence information recorded in the recording unit 111 and determines whether or not there is a movable range setting associated with the preset group that was changed in step S401. 【0057】 In step S402 of Figure 4, if the system control unit 101 determines that there is a movable range setting associated with the preset group changed in step S401 (S402 / Yes), the system proceeds to step S403. When the process proceeds to step S403 in Figure 4, the system control unit 101 determines whether the field of view (pan-tilt angle) currently set for the imaging device 100 falls within the range of motion of the range of motion setting that was affirmed in step S402. 【0058】 In step S403 of Figure 4, if the system control unit 101 determines that the pan-tilt angle currently set for the imaging device 100 is not within the range of motion of the range of motion setting that was affirmed in S402 (S403 / No), the system proceeds to step S404. When the process proceeds to step S404 in Figure 4, the system control unit 101 controls the pan-tilt angle of the imaging device 100 so that the pan-tilt angle of the imaging device 100 falls within the range of motion set which was affirmed in S402. 【0059】 When the process in step S404 in Figure 4 is completed, the process proceeds to step S405. Also, in step S403 in Figure 4, if the system control unit 101 determines that the pan-tilt angle currently set for the imaging device 100 is within the range of motion of the range of motion setting that was affirmed in S402 (S403 / Yes), the process proceeds to S405. When the system proceeds to step S405 in Figure 4, the system control unit 101 reflects the range of motion setting that was positively determined in step S402 (overwriting it as a new setting). 【0060】 When the process in step S405 in Figure 4 is completed, the process shown in the flowchart in Figure 4 is completed. Also, in step S402 in Figure 4, if the system control unit 101 determines that there is no movable range setting associated with the preset group changed in step S401 (S402 / No), the process shown in the flowchart in Figure 4 is completed. 【0061】 In the imaging device 100 (control device 110) according to the first embodiment described above, the system control unit 101 functions as the means described below. Specifically, the system control unit 101 functions as a first acquisition means 115 that acquires preset information which includes at least information regarding the field of view of the imaging unit 102. The system control unit 101 also functions as a second acquisition means 116 that acquires information regarding the control range setting for imaging by the imaging unit 102. Furthermore, the system control unit 101 functions as a recording control means 117 that performs control to record the corresponding preset information and the control range setting information in association with the recording unit 111. According to the imaging device 100 (control device 110) of the first embodiment, if one of the pieces of information—the preset information regarding the field of view of the imaging unit 102 and the control range setting information regarding imaging of the imaging unit 102—is changed, the other piece of information can be automatically set to appropriate information. For example, if the preset information is changed, the movable range setting information recorded in association with the changed preset information can be reflected (overwritten as a new setting). This eliminates the need for the user to manually switch the movable range setting later, for example, if the preset information is changed. 【0062】 In this embodiment, information from a preset group containing multiple presets is applied as the preset information associated with the control range setting information. However, the present invention is not limited to this form. For example, the present invention also includes a form in which information from a single preset (a standalone preset) is applied as the preset information associated with the control range setting information. 【0063】 Furthermore, in this embodiment, as control range setting information associated with preset information, information on the movable range is defined as the range in which the imaging unit 102 can perform panning and tilting operations. However, the present invention is not limited to this form. For example, the present invention also includes a form in which information on the visible range setting of the imaging unit 102, taking into account the field of view of the imaging unit 102, is applied as control range setting information associated with preset information. Also, for example, the present invention also includes a form in which information on the cropping range setting, which defines the range from which to be cropped out of the video (image) being captured by the imaging unit 102, is applied as control range setting information associated with preset information. Also, for example, the present invention also includes a form in which information on the drive prohibition range setting, which defines the range in which the imaging unit 102 is not driven, is applied as control range setting information associated with preset information. 【0064】 Furthermore, in this embodiment, as shown in Figure 4 for example, when the preset information is changed, the information corresponding to the changed preset information is set. However, the present invention is not limited to this form. For example, a form in which the preset information corresponding to the changed range of motion setting information is set when the range of motion setting information is changed is also applicable to the present invention. 【0065】 Furthermore, for example, when one imaging device 100 is shared between different shooting studios, or when the imaging position of the imaging device 100 changes within a shooting studio, the preset group and movable range settings may differ depending on the imaging position of the imaging device 100. In this embodiment, in such cases, for example, the preset group and movable range settings are associated with each imaging position of the imaging device 100 and recorded in the recording unit 111, so that appropriate information can be automatically set even when the imaging position of the imaging device 100 is switched. This improves user convenience. 【0066】 Furthermore, for example, when imaging a sports match using an imaging device 100 installed in a gymnasium, the shape of the court, areas of interest, prohibited areas for photography, etc., may differ depending on the sport being imaged. In this embodiment, in such cases, for example, a preset group and movable range setting are associated with each sport being imaged by the imaging device 100 and recorded in the recording unit 111, so that appropriate information can be automatically set even when the sport being imaged changes. This improves user convenience. 【0067】 (Second embodiment) Next, a second embodiment will be described. In the description of the second embodiment below, matters common to the first embodiment described above will be omitted, and matters that differ from the first embodiment described above will be explained. 【0068】 The schematic configuration of the imaging control system according to the second embodiment is the same as the schematic configuration of the imaging control system 10 according to the first embodiment shown in Figure 1. That is, the schematic configurations of the imaging device, control device, and client device according to the second embodiment are the same as the schematic configurations of the imaging device 100, control device 110, and client device 200 according to the first embodiment shown in Figure 1. 【0069】 The second embodiment is a configuration in which, when recording preset group information and movable range setting information in the recording unit 111 in association with each other, control is performed to expand or reduce the movable range in the movable range setting based on the preset group information and record the movable range setting information. This storage control is performed by the recording control means 117 of the system control unit 101. 【0070】 Figure 5 is a flowchart showing an example of a processing procedure in a method for associating information on movable range settings, which is a control method for the imaging device 100 (control device 110) according to the second embodiment. 【0071】 First, in step S501 of Figure 5, the system control unit 101 acquires information about the preset group currently selected by the client device 200, for example, as preset information that includes at least information about the field of view of the imaging unit 102. Specifically, the processing in step S501 is performed by the first acquisition means 115 of the system control unit 101. 【0072】 Next, in step S502 of Figure 5, the system control unit 101 acquires information on the currently selected movable range setting, for example, by the client device 200, as information on the control range setting related to imaging of the imaging unit 102. Specifically, the processing in step S502 is performed by the second acquisition means 116 of the system control unit 101. 【0073】 Next, in step S503 of Figure 5, the system control unit 101 determines whether or not the movable range setting acquired in S502 can be associated with the preset settings (pan position, tilt position, etc.) registered in the preset group information acquired in S501. 【0074】 In step S503 of Figure 5, if the system control unit 101 determines that the range of motion setting acquired in S502 cannot be associated with the preset setting registered in the preset group information acquired in S501 (S503 / Yes), the system proceeds to S504. When the process proceeds to step S504 in Figure 5, the system control unit 101 performs an expansion process for the movable range setting acquired in S502. 【0075】 If the processing in step S504 in Figure 5 is completed, the process proceeds to step S505. Also, in step S503 in Figure 5, if the system control unit 101 determines that the range of motion setting acquired in S502 corresponds to a preset setting registered in the preset group information acquired in S501 (S503 / No), the process proceeds to S505. When the process proceeds to step S505 in Figure 5, the system control unit 101 performs control to associate the preset group information acquired in S501 with the movable range setting information acquired in S502 or S504 and record it as association information in the recording unit 111. Specifically, the processing in step S505 is performed by the recording control means 117 of the system control unit 101. 【0076】 Once the process in step S505 of Figure 5 is completed, the process shown in the flowchart of Figure 5 is finished. 【0077】 Figure 6 shows a second embodiment and is a flowchart illustrating an example of a detailed processing procedure for the extension process of the movable range setting in step S504 of Figure 5. Figure 7 also shows a second embodiment and is a diagram illustrating the extension process of the movable range setting in step S504 of Figure 5. 【0078】 First, in step S601 in Figure 6, the system control unit 101 acquires the pan range and tilt range controlled from the pan position and tilt position of presets 1 (711) to 3 (713) registered in the preset group 710 in Figure 7. 【0079】 Next, in step S602 of Figure 6, the system control unit 101 obtains the pan range and tilt range from the movable range setting 720 of Figure 7, which is associated with the preset group. 【0080】 Next, in step S603 of Figure 6, the system control unit 101 determines whether the pan range of the preset group acquired in step S601 is greater than the pan range of the movable range setting acquired in step S602. 【0081】 In step S603 of Figure 6, if the system control unit 101 determines that the pan range of the preset group acquired in S601 is greater than the pan range of the movable range setting acquired in S602 (S603 / Yes), the system proceeds to step S604. When the process proceeds to step S604 in Figure 6, the system control unit 101 overwrites and retains the pan range of the movable range setting acquired in step S602 with the pan range of the preset group. 【0082】 If the process in step S604 in Figure 6 is completed, the process proceeds to step S605 in Figure 6. Also, in step S603 in Figure 6, if the system control unit 101 determines that the pan range of the preset group acquired in S601 is not greater than the pan range of the movable range setting acquired in S602 (S603 / No), the process proceeds to step S605. When the process proceeds to step S605 in Figure 6, the system control unit 101 determines whether the tilt range of the preset group acquired in step S601 is greater than the tilt range of the movable range setting acquired in step S602. 【0083】 In step S605 of Figure 6, if the system control unit 101 determines that the tilt range of the preset group acquired in S601 is greater than the tilt range of the movable range setting acquired in S602 (S605 / No), the system proceeds to step S606. When the system proceeds to step S606 in Figure 6, the system control unit 101 overwrites and retains the tilt range of the movable range setting acquired in step S602 with the tilt range of the preset group. 【0084】 If the process in step S606 in Figure 6 is completed, the process proceeds to step S607 in Figure 6. Also, in step S605 in Figure 6, if the system control unit 101 determines that the tilt range of the preset group acquired in S601 is not greater than the tilt range of the movable range setting acquired in S602 (S605 / No), the process proceeds to step S607. When the process proceeds to step S607 in Figure 6, the system control unit 101 records the movable range setting 730 shown in Figure 7, which was expanded in step S604 and / or step S606, in the recording unit 111. 【0085】 Once the process in step S607 in Figure 6 is completed, the process shown in the flowchart in Figure 6 is finished. 【0086】 In the second embodiment described above, when the recording control means 117 of the system control unit 101 records the preset group information and the movable range setting information in the recording unit 111, it performs the following processing. Specifically, the recording control means 117 of the system control unit 101 automatically expands the movable range in the movable range setting based on the preset group information (to match the drive range (pan-tilt range) of the preset position registered in the preset group). As a result, even if the movable range setting that was to be associated with a preset group cannot be associated with that preset group, it is not necessary to later expand the movable range setting to match the drive range of the preset group. Therefore, user convenience can be improved. 【0087】 In the second embodiment described above, the range of motion in the range of motion setting is expanded when associating the preset group with the range of motion setting, but the present invention is not limited to this form. For example, the recording control means 117 of the system control unit 101 can also be applied to the present invention in which it automatically reduces the range of motion in the range of motion setting based on the information of the preset group (to match the drive range of the preset position registered in the preset group). Alternatively, for example, the recording control means 117 of the system control unit 101 may change the preset position registered in the preset group so that it fits within the range of motion (pan-tilt range) in the range of motion setting. 【0088】 (Third embodiment) Next, a third embodiment will be described. In the description of the third embodiment below, matters common to the first and second embodiments described above will be omitted, and matters that differ from the first and second embodiments described above will be explained. 【0089】 The schematic configuration of the imaging control system according to the third embodiment is the same as the schematic configuration of the imaging control system 10 according to the first embodiment shown in Figure 1. That is, the schematic configurations of the imaging device, control device, and client device according to the third embodiment are the same as the schematic configurations of the imaging device 100, control device 110, and client device 200 according to the first embodiment shown in Figure 1, respectively. 【0090】 The second embodiment is a configuration in which, when adding or deleting a preset setting to a preset group and registering it, the system expands or shrinks the range of motion in the range of motion setting associated with the preset group and records the range of motion setting information. That is, the second embodiment is a configuration in which, when there is information about a preset to be changed, the system expands or shrinks the control range in the control range setting based on the information about the preset to be changed and records the control range setting information. This storage control is performed by the recording control means 117 of the system control unit 101. 【0091】 Figure 8 is a flowchart showing an example of a processing procedure in a control method for an imaging device 100 (control device 110) according to a third embodiment, which involves adding a preset setting. 【0092】 First, in step S801 of Figure 8, the system control unit 101 refers to the correspondence information recorded in the recording unit 111 and determines whether or not the movable range setting is associated with the preset group to which the preset setting is to be added. 【0093】 In step S801 of Figure 8, if the system control unit 101 determines that the range of motion setting is associated with the preset group to which the preset setting is to be added (S801 / Yes), the system proceeds to step S802. When the system proceeds to step S802 in Figure 8, the system control unit 101 determines whether the pan angle and tilt angle of the preset settings to be added can be associated with the range of motion settings that were affirmed in step S801. 【0094】 In step S802 of Figure 8, if the system control unit 101 determines that the pan angle and tilt angle of the preset setting to be added cannot be associated with the range of motion setting that was affirmed in step S801 (S802 / Yes), the system proceeds to S803. When the process proceeds to step S803 in Figure 8, the system control unit 101 performs the expansion process for the movable range setting that was determined to be positive in step S801. 【0095】 If the processing in step S803 in Figure 8 is completed, the process proceeds to step S804. Also, in step S802 in Figure 8, if the system control unit 101 determines that the pan angle and tilt angle of the preset setting to be added are associated with the range of motion setting that was affirmed in step S801 (S802 / No), the process proceeds to S804. Furthermore, in step S801 in Figure 8, if the system control unit 101 determines that the range of motion setting is not associated with the preset group to which the preset setting to be added is registered (S801 / No), the process proceeds to step S804. When the process proceeds to step S804 in Figure 8, the system control unit 101 adds the preset settings to be registered to the target preset group and records them in the recording unit 111. 【0096】 Once the process in step S804 in Figure 8 is completed, the process shown in the flowchart in Figure 8 is finished. 【0097】 Figure 9 shows a third embodiment and is a flowchart illustrating an example of a detailed processing procedure for the extension process of the movable range setting in step S803 of Figure 8. 【0098】 First, in step S901 of Figure 9, the system control unit 101 obtains the pan angle and tilt angle of the preset settings to be added. 【0099】 Next, in step S902 of Figure 9, the system control unit 101 obtains the pan range and tilt range from the movable range settings associated with the preset group to which the preset settings are to be added and registered. 【0100】 Next, in step S903 of Figure 9, the system control unit 101 determines whether the pan angle of the preset setting acquired in step S901 is greater than the pan range of the movable range setting acquired in step S902. 【0101】 In step S903 of Figure 9, if the system control unit 101 determines that the pan angle of the preset setting acquired in S901 is greater than the pan range of the movable range setting acquired in S902 (S903 / Yes), the system proceeds to step S904. When the process proceeds to step S904 in Figure 9, the system control unit 101 expands the pan range of the movable range setting acquired in step S902, taking into account the pan position of the preset setting acquired in step S901. 【0102】 If the process in step S904 in Figure 9 is completed, the process proceeds to step S905 in Figure 9. Also, in step S903 in Figure 9, if the system control unit 101 determines that the pan angle of the preset setting acquired in S901 is not greater than the pan range of the movable range setting acquired in S902 (S903 / No), the process proceeds to step S905. When the system proceeds to step S905 in Figure 9, the system control unit 101 determines whether the tilt angle of the preset setting acquired in step S901 is greater than the tilt range of the movable range setting acquired in step S902. 【0103】 In step S905 of Figure 9, if the system control unit 101 determines that the tilt angle of the preset setting acquired in S901 is greater than the tilt range of the movable range setting acquired in S902 (S905 / Yes), the system proceeds to step S906. When the process proceeds to step S906 in Figure 9, the system control unit 101 expands the tilt range of the movable range setting acquired in step S902, taking into account the tilt position of the preset setting acquired in step S901. 【0104】 If the process in step S906 in Figure 9 is completed, the process proceeds to step S907 in Figure 9. Also, in step S905 in Figure 9, if the system control unit 101 determines that the tilt angle of the preset setting acquired in S901 is not greater than the tilt range of the movable range setting acquired in S902 (S905 / No), the process proceeds to step S907. When the process proceeds to step S907 in Figure 9, the system control unit 101 records the expanded range of motion settings from step S904 and / or step S906 in the recording unit 111. 【0105】 Once the process in step S907 in Figure 9 is completed, the process shown in the flowchart in Figure 9 is finished. 【0106】 In the third embodiment described above, when the recording control means 117 of the system control unit 101 records information about preset groups and information about movable range settings in the recording unit 111, it performs the following processing. Specifically, when adding a preset setting to a preset group, the recording control means 117 of the system control unit 101 automatically expands the movable range setting associated with the preset group according to the pan angle and tilt angle of the preset setting. In the third embodiment described above, when adding a preset setting to a preset group, the movable range in the movable range setting is expanded, but the form of changing the movable range in the movable range setting is not limited to adding a preset setting. For example, when deleting a preset setting registered in a preset group, a form in which the movable range in the movable range setting is reduced according to the remaining preset settings registered in the preset group is also applicable to the present invention. 【0107】 (Fourth embodiment) Next, a fourth embodiment will be described. In the description of the fourth embodiment below, matters common to the first to third embodiments described above will be omitted, and matters that differ from the first to third embodiments described above will be explained. 【0108】 The schematic configuration of the imaging control system according to the fourth embodiment is the same as the schematic configuration of the imaging control system 10 according to the first embodiment shown in Figure 1. That is, the schematic configurations of the imaging device, control device, and client device according to the fourth embodiment are the same as the schematic configurations of the imaging device 100, control device 110, and client device 200 according to the first embodiment shown in Figure 1, respectively. 【0109】 The fourth embodiment is a configuration that takes into account the case where the user selects a movable range setting to associate with a preset group. Specifically, the fourth embodiment is a configuration in which the GUI screen displayed on the display unit 202 of the client device 200 is controlled to highlight control range settings that cannot be associated with a preset group or control range settings that can be associated with a preset group. This display control is performed by the display control means 118 of the system control unit 101. 【0110】 Figure 10 shows a fourth embodiment, illustrating an example of a GUI screen 1000 used by the user when selecting a range of motion setting to associate with a preset group. This GUI screen 1000 is displayed on the display unit 202 of the client device 200. 【0111】 The GUI screen 1000 shown in Figure 10 displays the number (No.) related to the mapping, and the preset group and range of motion setting assigned to each number related to the mapping. Selection item 1010 is an item for selecting the range of motion setting to associate with the preset group. The list of options 1020 is a dropdown display that appears when the user clicks on selection item 1010. 【0112】 Option 1021 is a movable range setting that cannot be associated with the pan range and tilt range of the preset settings registered in preset group 1. To prevent the user from selecting a movable range setting that cannot be associated with preset group 1, the display control means 118 of the system control unit 101 performs display control to highlight option 1021 by graying it out. 【0113】 Option 1022 is a movable range setting that corresponds to the pan range and tilt range of the preset settings registered in preset group 1. To allow the user to select a movable range setting that corresponds to preset group 1, the display control means 118 of the system control unit 101 performs display control by highlighting option 1022 in black. 【0114】 By displaying options 1021 and 1022 on the GUI screen 1000 shown in Figure 10, it becomes easier for the user to select the range of motion setting to associate with the preset group. 【0115】 In the fourth embodiment described above, control is performed to highlight control range settings that cannot be associated with a preset group or control range settings that can be associated with a preset group, but the present invention is not limited to this form. For example, conversely, when selecting a preset group to associate with a movable range setting, a form in which control is performed to highlight preset groups that cannot be associated with a control range setting or preset groups that can be associated with a control range setting is also applicable to the present invention. 【0116】 (Fifth embodiment) Next, a fifth embodiment will be described. In the description of the fifth embodiment below, matters common to the first to fourth embodiments described above will be omitted, and matters that differ from the first to fourth embodiments described above will be explained. 【0117】 The schematic configuration of the imaging control system according to the fifth embodiment is the same as the schematic configuration of the imaging control system 10 according to the first embodiment shown in Figure 1. That is, the schematic configurations of the imaging device, control device, and client device according to the fifth embodiment are the same as the schematic configurations of the imaging device 100, control device 110, and client device 200 according to the first embodiment shown in Figure 1, respectively. 【0118】 The fifth embodiment is one in which the imaging device 100 has set a movable range setting, and when the user switches to a preset group that does not correspond to the currently set movable range setting, the information of the currently set movable range setting is invalidated. This invalidation process is performed, for example, by the recording control means 117 of the system control unit 101. 【0119】 Figure 11 is a flowchart showing an example of a processing procedure in a control method for the imaging device 100 (control device 110) according to the fifth embodiment, which reflects (overwrites as new settings) the correspondence settings recorded in the recording unit 111. 【0120】 The processes in steps S1101 to S1105 in Figure 11 are the same as the processes in steps S401 to S405 in Figure 4, so their explanation will be omitted. 【0121】 In step S1102 of Figure 11, if the system control unit 101 determines that there is no movable range setting associated with the preset group changed in step S1101 (S1102 / No), the system proceeds to step S1106. When the process proceeds to step S1106 in Figure 11, the system control unit 101 invalidates the information of the movable range setting currently set in the imaging device 100. 【0122】 Once the process in step S1106 of Figure 11 is completed, the process shown in the flowchart of Figure 11 is finished. 【0123】 In the fifth embodiment described above, the system control unit 101 sets the range of motion settings, and when the user switches to a preset group that does not correspond to the currently set range of motion settings, the information of the currently set range of motion settings is invalidated. This improves user convenience because the preset settings registered in the preset group can be executed without considering the correspondence between the switched preset group and the invalidated range of motion settings. 【0124】 In the fifth embodiment described above, when a preset group is switched, the currently set range of motion settings that do not correspond to the preset group are disabled. However, the processing when a preset group is switched is not limited to this form. For example, the recording control means 117 of the system control unit 101 can also be applied to the present invention in which, when a preset group is switched, the recording control means 117 resets the range of motion settings to correspond to the preset group using the initial setting (default value) information. 【0125】 (Other embodiments) The present invention can also be realized by supplying a program that implements one or more of the functions of the above-described embodiments to a system or device via a network or storage medium, and by having one or more processors in the computer of that system or device read and execute the program. It can also be realized by a circuit (e.g., an ASIC) that implements one or more functions. This program and a computer-readable storage medium storing said program are included in the present invention. 【0126】 The embodiments of the present invention described above are merely examples of how the invention can be implemented, and the technical scope of the invention should not be interpreted as being limited by them. In other words, the present invention can be implemented in various forms without departing from its technical concept or its main features. 【0127】 This embodiment includes the following configurations, methods, and programs.
