Description

[Technical Field]

[0001] The present invention relates to an imaging device, a control method and a program therefor, and more particularly to a technique for selecting a frequency band to be used for wireless communication based on an image captured by the imaging device. [Background technology]

[0002] In recent years, there has been an increase in situations where multiple client devices communicate with a single device equipped with wireless server functionality (hereafter referred to as a wireless server). These wireless servers are now equipped with a function called "band steering" that automatically switches the frequency band to one that is appropriate for the environment for the client devices, such as smartphones, that are connected to the server.

[0003] However, if band steering is performed while a slave terminal is connected to this wireless server, communication will be interrupted when the frequency band is switched, causing discomfort to the user of the slave terminal.

[0004] In order to provide optimal communications to users, it is necessary to provide communications in a frequency band suitable for the slave terminal based on information obtained from the wireless server.

[0005] Patent Document 1 describes switching frequency bands depending on the degree of band congestion.

[0006] However, Patent Document 1 does not describe any criteria for determining whether to switch when the band is not congested.

[0007] Furthermore, Patent Document 2 describes that communication is attempted once in a specific frequency band, and if the communication is not established, the frequency band is switched and communication is performed.

[0008] However, in Patent Document 2, communication is interrupted when the frequency band is switched, just like in band steering. [Prior art documents] [Patent documents]

[0014] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the scope of the claimed invention. Although the embodiments describe multiple features, not all of these multiple features are necessarily essential to the invention, and multiple features may be combined arbitrarily. Furthermore, in the accompanying drawings, the same or similar components are designated by the same reference numerals and redundant explanations will be omitted.

[0015] <Embodiment 1> Fig. 1 is a diagram showing the configuration of a system including an imaging device 100 according to the present invention. The system shown in Fig. 1 detects a specific subject (object) from an image captured by the imaging device 100, and determines a frequency band for wireless communication with a slave terminal 120 according to the detected subject. The imaging device 100 shown in Fig. 1 has a wireless server function and can directly communicate wirelessly with the slave terminal 120.

[0016] The imaging device 100 detects a subject from a captured image and changes the frequency band for wireless communication with the slave terminal 120 according to the detection result. The subject is not limited to a person or an object. For example, it may be a two-dimensional marker placed on the floor. The subject to be detected is not limited to subjects that the imaging device has previously saved or learned. For example, subject information of the detection target may be acquired one by one from a server or the like. Alternatively, it may detect, for example, a person or a moving object rather than a specific person.

[0017] The slave terminal 120 is an external device capable of wireless communication with the imaging device 100. The slave terminal 120 is, for example, a smartphone, a PC, a tablet, or the like, and is not particularly limited to these as long as it is capable of wireless communication with the imaging device 100. Furthermore, the number of imaging devices 100 and slave terminals 120 is not particularly limited. For example, multiple slave terminals 120 may be connected to one imaging device 100.

[0018] 2 is a block diagram showing an example of the functional configuration of the imaging device 100 according to this embodiment. The imaging device 100 according to this embodiment includes an imaging unit 101, a driving unit 102, an image processing unit 103, a system control unit 108, a user control unit 109, and a communication unit 110.

[0019] The imaging unit 101 captures an image of a subject and converts the captured image into an electrical signal. The imaging unit 101 is composed of imaging lenses including a focus lens and a zoom lens, an imaging element, a mechanical drive system for driving them, and circuits.

[0020] The drive unit 102 is a mechanism for driving the imaging unit 101 in a pan or tilt direction, and is controlled by a drive control unit 104. The drive unit 102 is composed of a mechanical drive system that controls the attitude of the imaging device (pan or tilt drive), a motor as a drive source, and a sensor for identifying the drive position (attitude).

[0021] The image processing unit 103 generates image data by performing image processing such as noise removal or gamma correction on the electrical signals converted by the imaging unit 101. The image processing unit 103 according to this embodiment can also process commands received from the system control unit 108. For example, when the image processing unit 103 receives a command instructing a change in the pan / tilt position or zoom position, it drives the focus lens or zoom lens of the imaging unit 101 based on the command. Also, for example, when the image processing unit 103 receives a command instructing an image quality adjustment, it adjusts the image quality. The generated image data is transmitted to the system control unit 108.

[0022] The image processing unit 103 also includes a drive control unit 104 and an object detection unit 105. The drive control unit 104 processes commands related to drive control received from the system control unit 108 and the user control unit 109, and controls the drive amount or speed of the drive unit 102 or performs initialization based on the instructions of the commands. The object detection unit 105 detects an object to be detected in the image data and transmits the detected position to the system control unit 108. Since known detection processes can be used for the object detection process, detailed description thereof will be omitted.

[0023] The storage unit 106 is, for example, a ROM, and is an area for storing image data and subject information used by the imaging device 100, drive commands for the drive unit 102, wireless communication information, frequency band information, etc. The contents stored in this storage unit 106 are transmitted to and received from each operating unit via the system control unit 108.

[0024] The frequency band change unit 107 switches the frequency of wireless communication between a high frequency band and a low frequency band according to the detection result of the subject detection unit 105.

[0025] The system control unit 108 controls the entire imaging device 100. Here, the system control unit 108 performs wireless communication with the slave terminal 120 via the communication unit 110 using the frequency changed by the frequency band change unit 107. The system control unit 108 also analyzes control commands transmitted from the slave terminal 120 or the like via the user control unit 109, and transmits the control content to the drive control unit 104.

[0026] The user control unit 109 receives user input from the slave terminal 120. Note that the user input may be received from a hardware button attached to the imaging device body or an information processing terminal such as a wired PC. In this embodiment, the user's arbitrary frequency band setting is received from the user control unit, the setting is analyzed, and transmitted to the system control unit 108.

[0027] 3A and 3B are diagrams for explaining the control of the attitude of the imaging device 100 by the driving unit 102. Fig. 3A is a diagram of the imaging device 100 viewed from directly above the vertical axis, and Fig. 3B is a diagram of the imaging device 100 viewed from the side.

[0028] The imaging device 100 includes a bottom case 201, a turntable 202, a camera head support 203, and a camera head 204, and is configured with three pan heads 202 to 203. Sensors 205 to 208 for identifying the PTZ drive position and an angular velocity sensor 209 for measuring angular velocity are disposed in the driving unit 102. Note that since the sensors 205 to 208 and the angular velocity sensor 209 are disposed inside the imaging device 100, they are basically not visible from the outside, but for the sake of convenience in the example of Fig. 3 they are shown as being visible.

[0029] In this embodiment, the clockwise direction as viewed from the top in FIG. 3(a) is the positive direction of the pan angle, and the counterclockwise direction is the negative direction of the pan angle. Furthermore, the clockwise direction as viewed from the side in FIG. 3(b) is the positive direction of the tilt angle, and the counterclockwise direction is the negative direction of the tilt angle. The drive unit 102 drives the pan direction by rotating the turntable 202 about a vertical axis. The drive unit 102 drives the tilt direction by rotating the camera head 204 about an axis perpendicular to the vertical axis. In this embodiment, the camera can be driven from its initial position from −175 degrees to 175 degrees in the pan direction and from −25 degrees (diagonally downward) to 95 degrees (directly upward) in the tilt direction; however, this drive range is not particularly limited to these. For example, the camera may be rotatable 360 ​​degrees (endlessly) in the pan direction, or from −90 degrees to 90 degrees in the tilt direction.

[0030] Here, sensors 205 and 206 are disposed on a rotating portion on turntable 202 and detect driving in the pan direction of image capture device 100. In this example, sensor 205 is disposed at a position rotated more than 170 degrees (for example, 171 degrees) in the pan direction from the optical axis direction of the initial attitude, and sensor 206 is disposed at a position rotated more than −170 degrees (for example, −171 degrees) in the pan direction from the optical axis direction.

[0031] In this embodiment, the sensors 205 to 208 are configured with PIs as described above. Here, the process of detecting the drive position of the image capture device 100 in the pan direction will be described using the sensors 205 and 206 as an example. In the example of FIG. 3( a), a light-shielding wall (not shown) is installed at a fixed portion of the bottom case 201. When the sensors 205 and 206 are not shielded from light by the light-shielding wall, the light-receiving elements receive light from the light-emitting elements, and the AD value assumes a value close to a specified value (e.g., 1023). When the sensors 205 and 206 rotate to the position of the light-shielding wall by panning, the light-receiving elements are shielded from light, and the AD value of the PI assumes a value close to 0. In this embodiment, a threshold value is set to determine whether or not light is being shielded by the light-shielding wall. If the AD value is equal to or greater than the threshold value (1023 or less), it is determined that light is not being shielded, and if not, it is determined that light is being shielded. While this threshold value is not particularly limited, it is assumed here to be 512. By detecting this light shielding, it is detected that the image capture device 100 has reached a specific drive position. In this example, the PI is configured so that the light-emitting element and the light-receiving element are arranged in the rotating part and the light-shielding wall is installed in the fixed part, but the light-shielding wall may also be arranged in the rotating part and each element may be installed in the fixed part.

[0032] Furthermore, sensors 207 and 208 are disposed on a fixed portion on camera head support 203, and detect movement of imaging device 100 in the tilt direction. In this example, sensor 207 is disposed so as to detect rotation of more than 90 degrees (for example, 91 degrees) in the tilt direction from the optical axis direction of the initial position, and sensor 208 is disposed so as to detect rotation of more than −20 degrees (for example, −21 degrees) in the tilt direction from the optical axis direction of the initial position. In this example, light-shielding walls corresponding to sensors 207 and 208 (light-emitting elements and light-receiving elements disposed on the fixed portion) are disposed on the rotating portion of camera head 204, but the sensors may also be disposed on the rotating portion.

[0033] The angular velocity sensor 209 is disposed on the camera head 204 and detects the angular velocity in the yaw and pitch directions of the camera head 204. The X, Y, and Z axes shown in Figures 3(a) and 3(b) are examples of output axes of the angular velocity sensor 209. For example, when the pan angle is 0 degrees (initial attitude) in Figure 3(a), the angular velocity in the tilt direction can be detected by the X axis of the angular velocity sensor 209, and when the tilt angle is 0 degrees (initial attitude) in Figure 3(b), the angular velocity in the pan direction can be detected by the Y axis of the angular velocity sensor.

[0034] In this way, the imaging device 100 of this embodiment can capture an image of a subject by changing the imaging direction by rotating the camera head horizontally and vertically. In this embodiment, the imaging device 100 is driven in the pan and tilt directions, but this is not limiting. For example, the imaging device 100 may be configured so that it cannot be driven in the pan and tilt directions. Furthermore, a driving mechanism may not be present.

[0035] Hereinafter, each process performed by the image capturing apparatus 100 will be described with reference to Fig. 4 and Fig. 5. Fig. 4 is a flowchart showing an example of a process for changing the frequency band of wireless communication performed by the image capturing apparatus 100 according to this embodiment.

[0036] FIG. 4 is a flowchart illustrating an example of processing for performing wireless communication after the imaging device 100 is started up.

[0037] In S300, the imaging device 100 starts an initialization operation after power-on. The initialization operation at this time is, for example, an operation for setting initial positions in the pan direction and tilt direction. The imaging device 100 initializes the pan and tilt positions using sensor values ​​by operating the driver 102 to the drive positions of sensors 205, 206, 207, and 208. Note that the initialization operation does not have to be an initialization operation of the pan and tilt positions, and is not limited to these operations. For example, it may be an initialization process of the imaging engine.

[0038] In S310, the frequency band changing unit 107 changes the radio frequency band for communication with the slave terminal 120, and stores the changed frequency band in the storage unit 106. Details of this operation will be described later with reference to S311 to S314 in Fig. 5. In this way, the control unit selects one of the multiple frequency bands during the initialization operation of the imaging device.

[0039] In S301, the frequency band setting stored in the storage unit 106 in S310 is read out, and the communication unit 110 is initialized.

[0040] In S302, the reception of communication from the slave terminal via the communication unit 110 is started.

[0041] In S303, the system control unit 108 determines whether the number of communication frequency bands currently set is equal to or greater than a predetermined number. If it is determined that the number is equal to or greater than the predetermined number, the process proceeds to S304, and if it is equal to or less than the predetermined number, the process proceeds to S305.

[0042] In S304, the frequency band change unit 107 changes the frequency band from the current frequency band to a different frequency band, and changes the frequency band so that wireless communication with a new slave terminal that is subsequently connected is performed in the changed frequency band. When the change is complete, the process proceeds to S305.

[0043] In S305, the communication unit 110 determines whether communication with a connected terminal has become unstable. If the communication state is unstable or if there is a terminal where communication has been unintentionally interrupted, the process proceeds to step S306.

[0044] In S306, the imaging device 100 compares the information about the terminal with which communication has been interrupted with the information stored in the storage unit 107, and switches to communication using a different frequency band in the frequency band change unit 107. Thereafter, the processes from S303 to S306 are repeated and are executed continuously as long as the imaging device 100 is operating.

[0045] In this way, when the communication unit is performing wireless communication with the terminal in any one of the frequency bands selected from multiple frequency bands and the wireless communication becomes unstable (S305: YES), the control unit switches to a frequency band different from the selected frequency (S306), and the communication unit performs wireless communication with the slave terminal 120.

[0046] 5 is a flowchart showing an example of detailed processing of S310. In S311 to S314, the image capturing device 100 detects a specific object and determines a frequency band for communication.

[0047] In S311 , the imaging device 100 transmits the video captured by the imaging unit 101 to the image processing unit 103 .

[0048] In S312, the image processing unit 103 detects (detects) whether a specific object (specific object) is present in the video (image) transmitted from the imaging unit 101 using the subject detection unit 105 (detection unit). This specific object may be, for example, a specific person, a specific terminal, a marker with a specific image or code embedded therein, or the like, but is not limited to these. For example, it may be the detection of a human being. If a specific object is detected, the process proceeds to S313. If no specific object is detected, the process proceeds to S314. In this way, the detection unit performs the detection process for the specific object before communication is established by the communication unit.

[0049] In S313, the frequency band change unit 107 (also simply referred to as the control unit in this embodiment) switches to wireless communication using a high frequency band (for example, 5.0 GHz).

[0050] In S314, the frequency band change unit 107 (control unit) switches to wireless communication using a low frequency band (for example, 2.4 GHz).

[0051] In this way, the control unit selects a frequency band for wireless communication by the communication unit according to the detection result of the specific object by the detection unit. Specifically, when the detection unit detects a specific object, the control unit selects a frequency band (e.g., 5.0 GHz) higher than one of the frequency bands (e.g., 2.4 GHz) from among the multiple frequency bands.

[0052] According to this process, before communication with the slave terminal is established, the connection status between the imaging device and the slave terminal can be predicted and an optimal communication state can be established.

[0053] According to the present invention, a frequency band to be used for wireless communication can be selected based on an image captured by an imaging device, thereby reducing the possibility that, for example, a 5 GHz band communication will be allocated to wireless communication with a slave terminal carried by a user when the user is hidden by a surrounding obstruction or the like.

[0054] In this embodiment, an example in which the number of the image capturing device 100 and the slave terminal 200 is one has been described, but two or more of them may be used. Furthermore, while the image capturing is performed during the initialization process of the pan and tilt positions, this is not limiting. An image may be captured when no driving operation is being performed, and an object may be detected from the fixed-point image.

[0055] <Embodiment 2> In the first embodiment, a process for changing the frequency band of wireless communication by detecting a specific object from an image captured during initialization processing of the imaging device has been described. However, for example, when the imaging device is in a standby state, which does not turn off the power but cannot fully function as an imaging device, the communication environment changes significantly during that state, and it may be necessary to re-optimize communication with the slave terminal. From this perspective, the imaging device 100 according to this embodiment performs a process for determining the frequency band again when returning from the standby state to the normal state, in addition to the process according to the first embodiment. The imaging device 100 according to this embodiment has basically the same configuration as that according to the first embodiment and can perform the same process, so a redundant description will be omitted.

[0056] The imaging device 100 according to this embodiment has a function of receiving, via the communication unit 110, a request transmitted from the small terminal 120 to enter a standby state or to return from the standby state.

[0057] FIG. 6 is a flowchart showing an example of an operation performed by the imaging device 100 according to this embodiment to set a new communication frequency band when recovery control from a standby state is performed.

[0058] In S401, the communication unit 100 receives a command to return from standby mode, which is sent from one of the slave terminals 120. The received command is sent to the user control unit 109 and analyzed, and the analyzed content is sent to the drive control unit 104.

[0059] In S402, the drive control unit 104 starts a standby recovery operation based on the content transmitted in S401. The standby control operation at this time may be, for example, an initialization operation for the pan / tilt position similar to S300, but is not limited to this. For example, it may be a sensor initialization operation for starting video distribution.

[0060] Then, during the standby recovery operation, the communication frequency band is switched in S310.

[0061] In this way, when the control unit returns from a standby state in which some of the functions of the imaging unit are restricted to a state in which the restrictions are lifted (S401: YES, S402), the control unit again performs a detection process to detect a specific object using the detection unit, and selects a frequency band for wireless communication using the communication unit according to the detection result (S310).

[0062] According to this process, when the imaging device is restored from a state in which it is not powered off but is unable to fully function as an imaging device, it is possible to set the communication frequency band again based on the surrounding environment.

[0063] In this embodiment, the request to enter the standby state or return from the standby state is received only from the slave terminal 120, but this is not limiting. For example, the request may be transmitted from an external terminal for a specific purpose, such as an infrared remote control, or a PC connected to the imaging device 100 via IP.

[0064] <Embodiment 3> In the first and second embodiments, a process for determining a frequency band for wireless communication by detecting a specific object from an image captured before the imaging device fully functions has been described. However, as a result of actual communication, it is conceivable that stable communication cannot be achieved using the determined frequency band. From this perspective, the imaging device 100 according to this example performs a process for determining a frequency band for communication again based on the radio wave intensity when communication is established, in addition to the process according to the first embodiment. The imaging device 100 according to this embodiment basically has the same configuration as that according to the first embodiment and can perform the same process, so a duplicated description will be omitted.

[0065] FIG. 7 is a flowchart showing an example of an operation performed by the imaging device 100 according to this embodiment to determine that communication may become unstable if the communication strength is equal to or less than a threshold value, and change the frequency band.

[0066] In S501, the communication unit 110 checks the communication strength of communication with the slave terminal 120. If it is confirmed that the communication strength is equal to or less than a predetermined threshold, the process proceeds to S502. Note that the communication strength referred to here may be, for example, RSSI strength, but is not limited to this.

[0067] In S502, the frequency band changing unit 107 (control unit) changes the frequency band for communication with the slave terminal 120. Then, the changed frequency band is linked to the information of the slave terminal 120, and the storage unit 106 stores the information.

[0068] In this way, when the communication unit performs wireless communication in one of the frequency bands selected in S310 from among the multiple frequency bands and the communication strength of the wireless communication is equal to or less than a predetermined threshold (S501: YES), the control unit again selects a frequency band different from the selected frequency band (S502), for example, from 5.0 GHz to 2.4 GHz.

[0069] According to this type of processing, the frequency band for communication is determined based on the surrounding conditions, but even if communication is difficult in that frequency band, stable communication can be achieved by changing to a new frequency band.

[0070] Furthermore, some or all of the functional configuration of the above-described system may be implemented as hardware in the imaging device 1000 and the slave terminal 120.

[0071] Furthermore, the configurations and processes of the above-described embodiments may be applied to the imaging device 1000, the slave terminal 120, and the like.

[0072] Furthermore, the number of child terminals 120 constituting the system of the above-described embodiment is not limited as long as it is one or two or more.

[0073] The present invention can also be realized by executing the following process: a program that realizes the functions of the above-described embodiments is supplied to a system or device via a network or various recording media, and a computer (CPU, MPU, etc.) of the system or device reads and executes the program code. In this case, the program and the recording media storing the program constitute the present invention. [Explanation of symbols]
