Summary of the Invention

Problems to be Solved by the Invention

[0005] With the diversification of functions of imaging devices, the number of display items has increased and the hierarchicalization of display items has advanced. Therefore, when setting parameters of a desired setting item, the user has to select the menu step by step a plurality of times according to a certain procedure in order to obtain this setting item. Especially if the menu hierarchy is deep, it will take more operation time and the operability will deteriorate. When adjusting parameters in an imaging device including a plurality of cameras, if an operation such as selecting the menu step by step a plurality of times for each camera is required, the parameters cannot be adjusted efficiently.

[0006] The technology disclosed in Patent Document 1 allows users to know the difference between parameter setting information and management setting information, but it does not enable efficient parameter adjustment in an imaging device equipped with multiple cameras.

[Effects of the Invention]

[0009] According to the present invention, parameters can be efficiently adjusted in an imaging device equipped with multiple cameras. [Brief explanation of the drawing]

[Figure 10] This figure shows an example of the hardware configuration of the main part of an imaging device to which the present invention is applied. [Modes for carrying out the invention]

[0011] Preferred embodiments of the present invention will be described below with reference to the attached drawings. (First Embodiment) Figure 1 is a schematic diagram showing the configuration of the imaging device 1 according to the first embodiment. The imaging device 1 is a multi-camera imaging device equipped with four cameras (imaging means) 10a to 10d. Cameras 10a to 10d are arranged on a circular rail 2, and their shooting positions can be changed by moving them along the rail 2 using pan control. In addition, the shooting angle of view of cameras 10a to 10d can be changed by zoom control, focus control, and rotation control, respectively. In the following description, cameras 10a to 10d may also be referred to as cameras A to D.

[0012] When installing the imaging device 1 equipped with a plurality of cameras 10a to 10d as described above, it is necessary to adjust the parameters with the cameras 10a to 10d. The adjustment of the parameters performed when installing the imaging device 1 is called installation adjustment. Adjusting the parameters means that the user sets the parameters according to the desired imaging conditions. As the setting items for setting the parameters, there are setting items for setting parameters related to brightness (for example, shutter speed, aperture value, strobe emission state, ISO sensitivity, luminance), setting items for setting parameters related to color (for example, white balance, color temperature), setting items for setting parameters related to resolution, setting items for setting parameters related to frame rate, setting items for setting parameters related to focus, setting items for setting parameters related to signal format, setting items for setting the (day / night) mode, and the like.

[0013] Figure 2 is a diagram showing the configuration of the imaging device 1. The imaging device 1 includes cameras 10a to 10d, a communication unit 17, an acquisition unit 18, an identification unit 19, a control unit 20, a storage unit 21, an input unit 22, a display unit 23, and a management unit 24.

[0014] Camera 10a includes an imaging unit 11a, a lens driving unit 12a, a pan driving unit 13a, a tilt driving unit 14a, a rotation driving unit 15a, and a light amount sensor 16a. The imaging unit 11a includes a lens including a focus lens and a zoom lens, and an imaging element, and performs imaging of a subject and photoelectric conversion into an electrical signal. The lens driving unit 12a includes a driving system of the lens and a motor as a driving source, and is controlled by the control unit 20.

[0015] The pan driving unit 13a includes a mechanical driving system that performs a pan operation and a motor as a driving source, and is controlled by the control unit 20. The tilt driving unit 14a includes a mechanical driving system that performs a tilt operation and a motor as a driving source, and is controlled by the control unit 20. The rotation driving unit 15a includes a mechanical driving system that performs a rotation operation and a motor as a driving source, and is controlled by the control unit 20. The light quantity sensor 16a is a sensor that detects the intensity of light and converts it into an electrical signal.

[0016] Note that the other cameras 10b to 10d also have the same configuration, and their descriptions are omitted. Each of them includes an imaging unit 11b to 11d, a lens driving unit 12b to 12d, a pan driving unit 13b to 13d, a tilt driving unit 14b to 14d, a rotation driving unit 15b to 15d, and light quantity sensors 16b to 16d.

[0017] The communication unit 17 receives the photographed image data of the cameras 10a to 10d. Also, the communication unit 17 transmits and receives camera control commands between the control unit 20 and the cameras 10a to 10d. The camera control commands are used, for example, when adjusting parameters in the cameras 10a to 10d.

[0018] The acquisition unit 18 acquires the parameter setting information of the installed and adjusted camera (the camera with adjusted parameters) from the storage unit 21. The parameter setting information of the installed and adjusted camera includes information on which setting items the user adjusted the parameters during the installation adjustment in the installed and adjusted camera.

[0019] The specifying unit 19 specifies the setting items for adjusting parameters in the un-installed and un-adjusted camera (the camera with un-adjusted parameters) based on the parameter setting information acquired by the acquisition unit 18. The setting items for which parameters were adjusted in the installed and adjusted camera are expected to be adjusted by the user in the un-installed and un-adjusted camera as well. The specifying unit 19, for example, compares the value of the parameter set in the installed and adjusted camera with the initial value of the parameter, extracts the setting items for which the user adjusted the parameters, and uses these as the setting items for adjusting parameters in the un-installed and un-adjusted camera.

[0020] The control unit 20 comprehensively controls each component of the imaging device 1 and sets various parameters. Specifically, the control unit 20 issues control instructions such as focus and zoom to the lens drive units 12a to 12d. The control unit 20 also issues control instructions such as pan, tilt, and rotation to the pan drive units 13d to 13d, tilt drive units 14a to 14d, and rotation drive units 15a to 15d. Furthermore, the control unit 20 displays information regarding the setting items identified by the identification unit 19 on the display unit 23. At this time, the control unit 20 displays the setting items identified by the identification unit 19 in a way that allows the user to adjust the parameters. The function of the control unit 20 is realized, for example, by executing a program loaded by the CPU from the memory unit 21.

[0021] The memory unit 21 stores drive information for cameras 10a to 10d, such as pan, tilt, zoom, focus, and rotation, as well as setting information for cameras 10a to 10d. The memory unit 21 also stores parameter setting information for cameras 10a to 10d, field of view information, image quality information, and information such as the patrol position for preset patrols. Furthermore, the memory unit 21 stores programs executed by the control unit 20.

[0022] The input unit 22 prompts the user to input parameters for the setting items displayed on the display unit 23.

[0023] The display unit 23 is composed of a liquid crystal display device or the like. The display unit 23 displays images acquired from cameras 10a to 10d and notifications of camera events transmitted from cameras 10a to 10d. The display unit 23 also displays a graphical user interface (hereinafter referred to as GUI) for adjusting and checking parameters.

[0024] The management unit 24 manages cameras that have been installed and adjusted, and cameras that have not yet been installed and adjusted. The management unit 24 manages cameras that have been installed and adjusted, and cameras that have not yet been installed and adjusted, using a status management table 400 stored in the storage unit 21, for example, as shown in Figure 4(b). The status management table 400 contains the camera name and the status information of each camera, and it is possible to manage the status of cameras 10a to 10d, each of which has been installed and adjusted. "Installed and adjusted" means that the parameters have been adjusted after the imaging device 1 has been installed at the installation site. The user sets whether the camera has been installed and adjusted. "Not installed and adjusted" means that the parameters have not yet been adjusted after the imaging device 1 has been installed at the installation site, and the camera is in its initial state.

[0025] Referring to Figure 3, an example of the processing performed by the imaging device 1 will be explained. Figure 3(a) is a flowchart illustrating an example of the process for setting up and adjusting a camera. The flowchart in Figure 3(a) can be implemented, for example, by having the CPU execute a predetermined program. Here, cameras 10a to 10d are all in an unadjusted state, and the explanation proceeds assuming that the parameters of camera 10a are adjusted first to bring it into an adjusted state.

[0026] In step S100, the control unit 20 displays the settings necessary for adjusting the parameters of the camera 10a on the display unit 23 using a GUI, in accordance with the user's instructions in the menu.

[0027] In step S101, the control unit 20 prompts the user to input parameters via the input unit 22 for the setting items displayed on the display unit 23 in step S100. The control unit 20 stores the parameter setting information based on the parameter adjustments made here in the storage unit 21, and also sets it on the camera 10a via the communication unit 17, thereby ending this flowchart. Here, referring to Figure 4(a), the information 401 of the installed and adjusted parameters, which is the parameter setting information stored in the memory unit 21, will be explained. The information 401 of the installed and adjusted parameters includes status information 402 indicating that the system has been installed and adjusted. The user sets whether the system has been installed and adjusted. In addition, the information 401 of the installed and adjusted parameters includes parameter information 403 for each setting item for each function.

[0028] Figure 3(b) is a flowchart illustrating an example of the parameter adjustment process for an unadjusted camera. The flowchart in Figure 3(b) is implemented, for example, by the CPU executing a predetermined program. Here, we will proceed with the explanation assuming camera 10b is an unadjusted camera.

[0029] In step S200, the control unit 20 checks whether the information 401 of the installed and adjusted parameters is stored in the memory unit 21. If the information 401 of the installed and adjusted parameters is stored, the process proceeds to step S201. If the information 401 of the installed and adjusted parameters is not stored, the flowchart is exited. At this point, a message may be displayed on the display unit 23 instructing the camera 10b to be set to the installed and adjusted state (i.e., to perform the process shown in Figure 3(a)).

[0030] In step S201, the identification unit 19 identifies the setting items to be adjusted on the unadjusted camera 10b based on the information 401 of the installed and adjusted parameters, and stores the identification result in the storage unit 21.

[0031] In step S202, the control unit 20 displays information regarding the setting items identified in step S201 on the display unit 23 using a GUI. Referring to Figure 5, an example of a GUI displayed on the display unit 23 will be explained. Figure 5 shows an example of displaying information 500 regarding setting items identified by the identification unit 19 on the display unit 23 using a GUI. The information 500 regarding setting items identified by the identification unit 19 includes setting items 501 that are expected to be adjusted by the user on the unadjusted camera 10b, and their parameter input fields 502. Parameter input fields 502 with thick borders indicate that they are input targets for the input unit 22. The parameter input fields 502 to be input targets can be arbitrarily selected. In this example, the parameters for exposure, resolution, FPS (frame rate), Focus, and (day / night) mode have been adjusted on the adjusted camera 10a. The identification unit 19 displays these setting items as setting items 501, assuming they are settings that are expected to be adjusted by the user on the unadjusted camera 10b. Furthermore, the initial display of the parameter input field 502 may be set to show the initial value of the parameter, or it may be set to show the parameter value adjusted by the installed and adjusted camera 10a. The information regarding the setting items 500 is a display that gathers the setting items for exposure, resolution, FPS, Focus, and (day / night) mode, which are normally located in different layers, into a single layer based on the identification result of the identification unit 19.

[0032] In step S203, the control unit 20 prompts the user to input parameters via the input unit 22 into the parameter input field 502 of the setting item 501 displayed on the display unit 23 in step S202. The control unit 20 stores the parameter setting information based on the parameter adjustments made here in the storage unit 21, and also sets it on the camera 10b via the communication unit 17, thereby ending this flowchart.

[0033] As described above, based on the parameter adjustments made with the installed and adjusted camera, the system identifies the settings that need to be adjusted on the uninstalled and adjusted camera, and displays this information on the display unit 23. This eliminates the need to select menus multiple times in a stepwise manner when adjusting parameters on the uninstalled and adjusted camera, reducing the time required to find the settings. Therefore, parameter adjustments can be performed efficiently.

[0034] (Second embodiment) Next, a second embodiment will be described. The imaging device 1 according to the second embodiment has the same configuration as the imaging device 1 according to the first embodiment, so its description will be omitted. Hereafter, the description of the similarities with the first embodiment will be omitted, and the differences with the first embodiment will be described in detail.

[0035] Referring to Figure 6, an example of the processing performed by the imaging device 1 will be explained. Figure 6 is a flowchart illustrating an example of the process for adjusting parameters in an unadjusted camera. The flowchart in Figure 6 is implemented, for example, by the CPU executing a predetermined program. Here, we will proceed with the explanation assuming camera 10a is an adjusted camera and cameras 10b to 10d are unadjusted cameras.

[0036] In step S300, the control unit 20 refers to the status management table 400 stored in the memory unit 21 to determine whether or not it has detected an unadjusted camera. If an unadjusted camera is detected, the process proceeds to step S301. If no unadjusted camera is detected, this flowchart is exited.

[0037] In step S301, the control unit 20 checks whether the information 401 of the installed and adjusted parameters is stored in the memory unit 21. If the information 401 of the installed and adjusted parameters is stored, the process proceeds to step S302. If the information 401 of the installed and adjusted parameters is not stored, the process exits this flowchart.

[0038] In step S302, the identification unit 19 identifies the setting items to be adjusted for the unadjusted cameras 10b to 10d based on the information 401 of the installed and adjusted parameters, and stores the identification result in the storage unit 21.

[0039] In step S303, the control unit 20 displays information regarding the setting items identified in step S302 on the display unit 23 using a GUI. Referring to Figure 7, an example of a GUI displayed on the display unit 23 will be explained. Figure 7 shows an example of displaying information 700 to 702 regarding setting items identified by the identification unit 19 on the display unit 23 using a GUI. As shown in Figure 7, information 700 to 702 regarding setting items is displayed for each of the unadjusted cameras B to D. The details of each of the information 700 to 702 regarding setting items are the same as the information 500 regarding setting items in the first embodiment, so their explanation will be omitted. Information 701 regarding the setting items of camera C, which has a thick border, indicates that it is an input target for the input unit 22.

[0040] In step S304, the control unit 20 prompts the user to input parameters via the input unit 22 into the parameter input field of the setting item displayed on the display unit 23 in step S303. The control unit 20 stores the parameter setting information based on the parameter adjustments made here in the storage unit 21, and also sets it to the corresponding camera (camera C (10c) in the example of Figure 7) via the communication unit 17, and terminates this flowchart. Before terminating the processing of this flowchart, the user can select a camera other than camera 10c and repeat the same process.

[0041] As described above, after detecting cameras that have not been properly positioned, the system identifies the settings that need to be adjusted on the unadjusted cameras based on the parameter adjustments made on the adjusted cameras, and displays this information on the display unit 23 for each unadjusted camera. This eliminates the need to select menus multiple times in a stepwise manner when adjusting parameters on unadjusted cameras, reducing the time required to find the settings. Furthermore, it becomes possible to adjust the parameters of multiple unadjusted cameras all at once. Therefore, parameter adjustment can be performed more efficiently.

[0042] (Third embodiment) Next, a third embodiment will be described. The imaging device 1 according to the third embodiment has the same configuration as the imaging device 1 according to the first embodiment, so its description will be omitted. Hereafter, the description of the similarities with the first embodiment will be omitted, and the differences with the first embodiment will be described in detail. In the first and second embodiments, installation and adjustment were described. Even after installation and adjustment, it may be necessary to adjust the parameters of cameras 10a to 10d due to events such as changes in ambient light intensity. In the third embodiment, parameter adjustment after installation and adjustment will be described.

[0043] Referring to Figure 8, an example of the processing performed by the imaging device 1 will be explained. Figure 8 is a flowchart illustrating an example of the parameter adjustment process for a pre-installed and adjusted camera. The flowchart in Figure 8 is implemented, for example, by the CPU executing a predetermined program. Here, cameras 10a to 10d are assumed to be pre-installed and adjusted cameras.

[0044] In step S400, the control unit 20 determines whether or not an event has been detected in any of the cameras 10a to 10d. In this embodiment, the determination of whether or not a change in ambient light intensity has been detected is made based on the change in the sensor values ​​of the light intensity sensors 16a to 16d. In this example, we will proceed with the explanation assuming that a change in ambient light intensity has been detected by camera C (10c).

[0045] In step S401, the control unit 20 checks whether the information 401 of the installed and adjusted parameters is stored in the memory unit 21. If the information 401 of the installed and adjusted parameters is stored, the process proceeds to step S402. If the information 401 of the installed and adjusted parameters is not stored, the process exits this flowchart.

[0046] In step S402, the identification unit 19 identifies the setting items to be adjusted on the installed and adjusted cameras 10b to 10d based on the event detected in step S400, in other words, the setting items that should be adjusted in relation to the event, and stores the identification result in the storage unit 21. If the event is a change in ambient light, the user is expected to adjust the parameter, for example, using the setting item "exposure".

[0047] In step S403, the control unit 20 displays information about the setting items on the display unit 23 in a GUI based on the information 401 of the installed and adjusted parameters. Referring to Figure 9, an example of a GUI displayed on the display unit 23 will be explained. Figure 9 shows an example of displaying information 900 to 903 regarding the installed and adjusted settings on the display unit 23 using a GUI. As shown in Figure 9, information 900 to 903 regarding the settings is displayed for each installed and adjusted camera A to D. The details of each of the information 900 to 903 regarding the settings are the same as the information 500 regarding the settings in the first embodiment, and therefore their explanation will be omitted.

[0048] In step S404, the control unit 20 displays information regarding the camera setting item (in this example, information regarding the camera setting item 902) where the event detected in step S400 occurred, highlighting it (for example, by making it a thick border). Furthermore, the control unit 20 displays the parameter input field 904 of the setting item (in this example, the setting item "exposure") identified in step S402, highlighting it (for example, by making it a thick border).

[0049] In step S405, the control unit 20 prompts the user to input parameters via the input unit 22 into the parameter input field 904 of the setting item that was displayed in conjunction on the display unit 23 in step S403. The control unit 20 stores the parameter setting information based on the parameter adjustments made here in the storage unit 21, and also sets it to the corresponding camera (camera C(10c) in the example of Figure 9) via the communication unit 17, and terminates this flowchart. Before terminating the processing of this flowchart, the user may select a camera other than camera C(10c) through user operation and prompt the user to input parameters for the setting item "exposure" via the input unit 22.

[0050] As described above, based on events detected by the installed and adjusted camera, the system identifies the settings that require parameter adjustment on the camera and displays that information on the display unit 23. This eliminates the need to select menus multiple times in a stepwise manner when adjusting parameters in response to events, reducing the time required to find the settings. Therefore, parameter adjustment can be performed efficiently.

[0051] In this embodiment, we have used the detection of changes in ambient light intensity as an example of an event, but we are not limited to this. For example, we could analyze the image captured by the camera and detect changes in the frequency components (sharpness) of the captured image. If the event is a change in the frequency components of the captured image, the user is expected to adjust the parameter, for example, in the setting item "Focus".

[0052] Figure 10 shows an example of the hardware configuration of the main parts of an imaging device to which the present invention is applied. The imaging device comprises a CPU 101, a memory 102, a storage device 103, an input device 104, and an output device 105, each of which is interconnected by a bus 106. The CPU 101 executes the program stored in the storage device 103. This realizes the functions of the identification means, display control means, and management means of the present invention. The memory 102 temporarily stores the program and data read by the CPU 101 from the storage device 103. The memory 102 is also used as an area for the CPU 101 to execute various programs. The storage device 103 stores the operating system (OS), various programs, and various data. The input device 104 is a functional unit that receives input from the user, such as a keyboard or mouse. The output device 105 outputs the information input by the input device 104 and the execution results of the program executed by the CPU 101.

In other words, the present invention can be implemented in various forms without departing from its technical concept or its main features.
