[0007] Hereinafter, the embodiments will be described in detail with reference to the attached drawings. Note that the following embodiments do not limit the invention according to the claims. Although the embodiments describe a number of features, not all of these features are essential to the invention, and the features may be combined in any manner. Furthermore, in the attached drawings, the same reference numbers are used for the same or similar configurations, and duplicated descriptions are omitted.

[0008] [Embodiment 1] Hereinafter, a first embodiment will be described with reference to the drawings. First, a system configuration corresponding to the embodiment will be described with reference to Fig. 1(A). Fig. 1(A) is a diagram showing an example of the configuration of a system corresponding to the embodiment. A system 10 corresponding to the present embodiment is configured by connecting an imaging device 100 to a user terminal 300 via a network 200.

[0009] In this embodiment, anti-shake control is described in which anti-shake ON / OFF information set by the user on the user terminal 300 is stored in association with position information of the rotation mechanism of the image capture device 100, and anti-shake control is performed by controlling the rotation mechanism. The anti-shake processing of this embodiment is effective when the image capture device 100 is installed in an environment where it shakes (or can be said to "shake" or "vibrate", but hereinafter, "shake" will be used collectively) at low frequencies, such as a ship or a bridge.

[0010] The imaging device 100 is configured to include an imaging section 110 composed of a lens section 111 and an imaging element 112, an image processing section 120, an interface section 130, a vibration detection section 140, a control section 150, a storage section 160, and rotation mechanisms 170 and 171.

[0011] The imaging unit 110 is configured to include a lens unit 111 and an imaging element 112. The imaging direction of the imaging unit 110 is changed and fixed by rotation mechanisms 170 and 171, which will be described later. In this embodiment, the imaging unit 110 is described as including the lens unit 111 and the imaging element 112 therein, but it may also include an image processing unit 120 and an interface unit 130 therein.

[0012] A scene captured by the imaging device 100 is imaged on the imaging element 112 through the lens unit 111. The lens unit 111 can be configured to have an optical lens, an optical filter, an aperture mechanism, and a drive system for driving each of them. The optical filter may include, for example, a visible light cut filter, an infrared light cut filter, and an ND filter. The drive system acquires setting values ​​from the image processing unit 120 and the control unit 150, and switches the optical lens and the optical filter according to the acquired setting values.

[0013] The imaging element 112 is, for example, a CMOS or CCD image sensor, and outputs an analog signal corresponding to the light imaged by the lens unit 111. This analog signal is converted into a digital signal by an A / D conversion circuit (not shown) and output to the image processing unit 120 as an image signal.

[0014] The image processing unit 120 performs predetermined image processing, such as development processing, filter processing, sensor correction, noise removal, etc., on the image signal received from the image sensor 112. When performing exposure adjustment, a setting value is sent to the lens unit 111 and the image sensor 112, and adjustment is made so that an appropriately exposed image can be obtained. Details of exposure adjustment are omitted here, as it is performed using known techniques. The image generated by the image processing unit 120 is sent to the interface unit 130.

[0015] The interface unit 130 communicates with the user terminal 300 via a network 200, which will be described later. The image received from the image processing unit 120 is transmitted to the user terminal 300 via the network 200. In addition, information on the vibration reduction settings of the imaging device 100 received from the user terminal 300 (hereinafter referred to as "vibration reduction setting information") is provided to the control unit 150.

[0016] The vibration detection unit 140 acquires vibration information of the imaging device 100. The vibration detection unit 140 is composed of a sensor such as a gyro sensor or an acceleration sensor that detects the direction and amount of vibration of the imaging device 100, and selects a sensor according to the installation environment of the imaging device 100. In this embodiment, it is assumed that the imaging device 100 is installed in an environment where it vibrates at a low frequency, such as a ship or a bridge, and therefore a sensor suitable for acquiring this vibration is desirable. The vibration detection unit 140 sends the value acquired by the sensor to the control unit 150 as vibration information.

[0017] The control unit 150 controls various operations of the imaging device 100. The control unit 150 also controls the rotational positions of the rotation mechanisms 170 and 171 in two control modes. The first control mode is a mode in which the rotational positions of the rotation mechanisms 170 and 171 are controlled based on information on an imaging range specified by a user and received via the interface unit 130, and is used when a range to be imaged by the imaging device 100 is specified or changed. The second control mode is a mode in which the rotational positions of the rotation mechanisms 170 and 171 are controlled based on shaking information of the imaging device 100 acquired from the shaking detection unit 140, to perform vibration reduction so as to cancel out shaking.

[0018] If the user has sent anti-shake setting information, the control unit 150 determines whether or not to perform anti-shake control based on that information, and if not, based on the anti-shake settings stored in the storage unit 160, which will be described later. Furthermore, if the control unit 150 receives anti-shake setting information set by the user, the control unit 150 sends it to the storage unit 160 together with the rotation positions of the rotation mechanisms 170 and 171.

[0019] The storage unit 160 stores the rotational position and the vibration isolation setting information received from the control unit 150 in association with each other. The vibration isolation setting information for each rotational position is uniquely determined, and when vibration isolation setting information is obtained again from the control unit 150, the new setting information is stored.

[0020] The rotation mechanisms 170 and 171 have a pan-tilt mechanism that holds the imaging unit 110 and faces it in the direction in which the user wants to capture an image. The rotation mechanisms 170 and 171 correspond to pan control and tilt control, respectively, and are composed of a driving motor such as an ultrasonic motor or a stepping motor, and drive the orientation of the imaging device 100 to the rotation position received from the control unit 150. The pan-tilt mechanism also operates to cancel out shaking of the imaging device 100 in the above-mentioned second mode.

[0021] The network 200 is composed of, for example, a plurality of routers, switches, cables, etc. that satisfy a communication standard such as Ethernet. In this embodiment, the communication standard, scale, and configuration are not important as long as the interface unit 130 and the user terminal 300 can communicate with each other. For example, the network 200 may be composed of the Internet, a wired LAN (Local Area Network), a wireless LAN (Wireless LAN), a WAN (Wide Area Network), etc. Similarly, the interface unit 130 and the user terminal 300 also have a transmission / reception function that satisfies the above contents.

[0022] The user terminal 300 is configured as a personal computer (hereinafter, PC), a smartphone, a tablet terminal, or the like. Taking a PC as an example, an image received via the network 200 is displayed to the user on a display. The user checks the image displayed on the display, and inputs an ON / OFF setting for image stabilization, a designation of an imaging range, and the like, from a user interface of the PC. The setting information input to the user terminal 300 is sent to the interface unit 130 via the network 200.

[0023] Next, FIG. 1B is a diagram showing an example of a hardware configuration of an imaging device 100 corresponding to an embodiment. The imaging device 100 has a CPU 101, a ROM 102, a RAM 103, a hard disk drive (HDD) 104, a network interface 105, an input device 106, and a display device 107. The imaging device 100 further has an imaging unit 110, a shake detection unit 140, and rotation mechanisms 170 and 171. The network interface 105 is connected to a network 200. The CPU 101 is a control device that controls the imaging device 100, and can function as an image processing unit 120 and a control unit 150. The ROM 102 stores a program for the CPU 101 to control the imaging device 100. Note that a secondary storage device may be provided instead of the ROM 102.

[0024] The RAM 103 is a memory for the CPU 101 to expand a program read from the ROM 102 and execute processing. The RAM 103 is also used as a temporary storage memory, a storage area for temporarily storing data to be subjected to various processes. The RAM 103 can operate as the storage unit 160 in FIG. 1A. The HDD 104 can store captured images. The network interface 105 is a circuit for communicating via the network 200, and can function as the interface unit 130. The CPU 101 acquires anti-shake settings and the like from the user terminal 300 via the network 200. The display device 107 is a device such as a display that displays an image and an area frame. The input device 106 has a pointing device, a touch panel, a button, a switch, and the like for indicating the display position of the display area of ​​the display device 107.

[0025] Next, the flow of processing for anti-shake control in this embodiment will be described with reference to Fig. 2. Anti-shake control may be started, for example, when imaging device 100 starts imaging. The processing corresponding to Fig. 2 can be realized, for example, by CPU 101 functioning as control unit 150 executing a corresponding program (stored in ROM 103 or the like).

[0026] First, in S200, the control unit 150 sets an initial value of the vibration isolation setting information at each rotational position of the rotation mechanisms 170 and 171 (information on whether or not to perform vibration isolation (ON / OFF) at each rotational position). The initial value may be stored in the memory unit 160 in advance, or may be set by the control unit 150. The memory unit 160 holds the setting value at the end of the previous vibration isolation control process, and this may be used as the initial value. The memory unit 160 obtains the initial rotational positions of the rotation mechanisms 170 and 171 from the control unit 150, and sends the vibration isolation setting information (initial value) linked to that rotational position to the control unit 150.

[0027] In the next step S201, the imaging unit 110 captures an image based on the setting information of the imaging range acquired from the control unit 150, and the control unit 150 controls the operation of the rotation mechanisms 170 and 171 based on the vibration reduction setting information. Here, the setting information of the imaging range is information set in the user terminal 300, and the control unit 150 acquires it from the interface unit 130 via the network 200. When vibration reduction is performed with the vibration reduction setting information ON, the control unit 150 controls the rotation mechanisms 170 and 171 based on the vibration information received from the vibration detection unit 140 while the imaging unit 110 is capturing an image so that image shaking is eliminated.

[0028] Here, referring to FIG. 3, an example of an operation for suppressing image shaking by controlling the rotation mechanism 170 will be described. FIG. 3(A) shows a state in which the imaging unit 110 is held by the rotation mechanism 170 with an axis in the direction into the paper. Image shaking can be canceled or suppressed by keeping the imaging direction a constant. For example, as shown in FIG. 3(B), when the imaging device 100 rotates counterclockwise due to shaking, the rotation mechanism 170 is controlled so that the imaging unit 110 faces downward. Also, as shown in FIG. 3(C), when the imaging device 100 rotates clockwise, the rotation mechanism 170 is controlled so that the imaging unit 110 faces upward. Similarly, the rotation mechanism 171 can perform a rotation operation in a direction that cancels or suppresses shaking of the imaging unit 110. Also, when the image stabilization setting information is set to OFF, the control unit 150 fixes the rotation positions of the rotation mechanisms 170 and 171, and the imaging unit 110 captures an image.

[0029] In the next S202, the control unit 150 determines whether or not the user has changed the settings. The change in settings here refers to at least one of the rotation position information and the vibration isolation setting information, and the control unit 150 acquires the changed information set by the user on the user terminal 300 via the network 200. If the settings have been changed, the process proceeds to S203, and if the settings have not been changed, the process returns to S201 and imaging continues without changing the settings.

[0030] In S203, the control unit 150 determines whether the setting changes acquired in S202 include a change in the imaging range. If there is a change in the imaging range, the process proceeds to S204, where the rotation positions of the rotation mechanisms 170 and 171 are changed in the first mode. If there is no change in the imaging range, the process proceeds to S205 without changing the rotation positions.

[0031] In S204, the control unit 150 changes the rotational positions of the rotation mechanisms 170 and 171. This rotational position information is generated by the control unit 150 converting the setting information of the imaging range received from the interface unit 130. As a conversion method, for example, the control unit 150 converts the setting information of the specified imaging range into rotational position information of the rotation mechanism 170 and the like based on a conversion table. The generated rotational position information is sent from the control unit 150 to the rotation mechanisms 170 and 171, and the rotation mechanisms 170 and 171 drive the motors to the rotational positions to change the rotational positions. After that, the process proceeds to S205.

[0032] In the next S205, the control unit 150 determines whether the setting changes acquired in S202 include a change in the image stabilization setting information. If a change in the image stabilization setting information is included, the process proceeds to S206 to update the setting values ​​stored in the storage unit 160, and if not, the process proceeds to S206. In S206, the control unit 150 updates the setting values ​​stored in the storage unit 160. As described above, in this embodiment, the setting of whether or not to perform image stabilization is uniquely determined for each rotation position.

[0033] In the next S207, the image stabilization setting corresponding to the rotational positions of the rotation mechanisms 170 and 171 is updated so that the control unit 150 operates according to at least one of the rotational positions and the image stabilization setting changed as described above. By the above processes from S203 to S207, the imaging device 100 becomes able to capture an image based on the imaging range and the image stabilization setting set by the user.

[0034] In the next S208, the control unit 150 determines whether the imaging device 100 ends imaging. If imaging is to be continued, the process proceeds to S201, and if imaging is to be ended and the operation of the imaging device 100 is to be stopped, the sequence ends. If imaging is to be ended, the setting values ​​stored in the storage unit 160 during the sequence may be deleted or may be held until the next startup.

[0035] According to this embodiment, the ON / OFF information of the vibration isolation control is stored as a vibration isolation setting in association with the position information of the rotation mechanism, and vibration isolation control can be performed according to the position information of the rotation mechanism.

[0036] [Embodiment 2] Next, a second embodiment will be described with reference to the drawings. First, a system configuration corresponding to the embodiment will be described with reference to Fig. 4. Fig. 4 is a diagram showing an example of the configuration of a system corresponding to the embodiment. A system 40 corresponding to this embodiment is configured by connecting a display unit 500 and an input unit 510 to an imaging device 400.

[0037] In this embodiment, the imaging device 400 is equipped with two vibration detection units with different characteristics in order to realize two different vibration isolation functions. As a result, in this embodiment, in addition to the installation environment assumed in the first embodiment, it is also effective in an installation environment in which the dominant vibration frequency differs depending on the imaging range and the vibration isolation function used as a countermeasure differs. The imaging device 400 realizes vibration isolation (first vibration isolation) for the case of vibration with low frequency and large amplitude shown in the first embodiment, and vibration isolation (second vibration isolation) that corrects image vibration by correction of the optical system (or by image processing) for the case of vibration with high frequency and small amplitude.

[0038] The imaging device 400 corresponding to this embodiment has a configuration in which, compared to the structure of the imaging device 100 shown in embodiment 1, the lens section 411 in the imaging unit 110 is changed, a shake detection section 412 is added, and a calculation section 420 and an interface section 430 are added.

[0039] Lens unit 411 has an anti-shake mechanism corresponding to this embodiment in addition to the mechanism of lens unit 111 shown in embodiment 1. Lens unit 411 can perform anti-shake control by acquiring high-frequency shake information from shake detection unit 412, calculating a target position of a correction lens for correcting vibration based on the high-frequency shake information, and moving the correction lens from a current position to the target position. Since publicly known technology can be used for the anti-shake mechanism and its functions, further details will not be described in this embodiment.

[0040] The shake detection unit 412 acquires shake information related to the imaging unit 410. As with the shake detection unit 140 shown in the first embodiment, a gyro sensor and an acceleration sensor can be used for the configuration. However, in this embodiment, the shake detection unit 412 acquires shake information for performing vibration isolation for high-frequency shake. Therefore, it is desirable for the shake detection unit 412 to select a sensor suitable for detecting shakes of small amplitude at high frequencies. The shake detection unit 412 provides a value indicating the direction and amount of shake acquired by the sensor to the lens unit 411 as high-frequency shake information.

[0041] In this embodiment, a technique for correcting image shake by cropping a captured image can also be used to prevent vibration from high-frequency shaking. In this case, the shake detection unit 412 sends high-frequency shaking information to the image processing unit 120 instead of the lens unit 411 to perform vibration prevention processing. For example, when the image processing unit 120 receives high-frequency shaking information, it can calculate the amount of movement of the image to offset the shaking information, and correct the image shake by moving the cropped image in a direction and amount that offsets the amount of movement. Alternatively, it can correct the image shake by shifting the crop position in a direction and amount that offsets the amount of movement and then cropping the image. Since this processing can use a known technique, further details will not be described in this embodiment.

[0042] In this embodiment, the first and second vibration reductions are switched depending on the frequency of the vibration, but the vibration frequency may be different between the optical vibration reduction and the vibration reduction by image processing. Specifically, the vibration frequency of the object of the optical vibration reduction is lower than the vibration frequency in the vibration reduction by image processing. In this case, the vibration detection unit 412 instructs the lens unit 411 to perform the second vibration reduction by optical vibration reduction depending on the detected vibration frequency, and instructs the image processing unit 120 to perform the third vibration reduction by image processing when a higher frequency is detected.

[0043] The calculation unit 420 judges whether or not the first vibration reduction is necessary based on the image generated by the image processing unit 120 and the vibration reduction setting information set by the control unit 150. Whether or not the first vibration reduction is necessary is judged based on whether or not the subject is shaking as the same as the environment in which the imaging device 400 is installed. For example, if the imaging device 400 is installed on a ship, it is judged based on whether the subject is the ship (inside the ship) or outside the ship (e.g., the sea, another ship, etc.). For example, if the subject to be imaged is inside the ship, the first vibration reduction is not necessary, whereas if the subject to be imaged is outside the ship, the first vibration reduction is necessary.

[0044] A specific example of the determination will be described with reference to Fig. 5. Fig. 5(A) shows an example of an image acquired when the first vibration isolation is ON, and Fig. 5(B) is an image acquired when the first vibration isolation is OFF. In Fig. 5(A), the first vibration isolation is ON, so the first vibration isolation works to cancel out the rocking of the ship, so that a still image of the subject outside the ship is captured, while a rocked image is recorded of the subject inside the ship. In Fig. 5(B), the first vibration isolation is OFF, so the ship rocks along with the ship, so a still image of the ship is captured, while a rocked image of the outside of the ship is captured.

[0045] As shown here, when the first vibration reduction is turned ON / OFF, the shaking occurs in the opposite direction inside and outside the ship, so it is possible to detect the boundary between inside and outside the ship and determine whether the imaging range is inside or outside the ship. When imaging inside the ship, the first vibration reduction is not necessary, but the second vibration reduction is performed to reduce vibration caused by high frequency shaking. On the other hand, when imaging outside the ship, the first vibration reduction is performed. Whether inside or outside the ship Toto By storing the image stabilization setting information in the storage unit 160 in association with the image stabilization setting information, the image stabilization function ON / OFF Make the switch.

[0046] The interface unit 430 transmits an image to the display unit 500 and receives user input from the input unit 510. The configuration needs to be adapted to the interface of the display unit 500 and the input unit 510. For example, the configuration may be HDMI or SDI, or an interface corresponding to a uniquely designed remote control. The display unit 500 displays an image acquired by the imaging device 400 to the user, and is configured, for example, by a monitor. The input unit 510 is used for the user to set the image stabilization for the imaging device 400. In FIG. 4, both the display unit 500 and the input unit 510 are connected to the imaging device 400 from the outside, but may be included as a configuration of the imaging device 400. In that case, for example, the display unit 500 may be configured as an LCD, and the input unit 510 may be configured as a push button.

[0047] The hardware configuration of the imaging device 400 in this embodiment is almost the same as that described in Fig. 1(B). However, in this embodiment, a shake detection unit 412 is further provided in addition to the configuration in Fig. 1(B), and the CPU 101 can also function as a calculation unit 420. Furthermore, the display device 107 can function as a display unit 500, and the input device 106 can function as an input unit 510.

[0048] Next, the flow of processing of anti-shake control in this embodiment will be described with reference to Fig. 6. Anti-shake control may be started, for example, when imaging device 400 starts imaging. The processing corresponding to Fig. 2 can be realized, for example, by CPU 101 functioning as control unit 150 executing a corresponding program (stored in ROM 103 or the like).

[0049] First, in S600, the mode is switched to a scan mode for anti-shake setting information at each rotational position of the rotation mechanisms 170, 171 in the environment in which the imaging device 400 is installed. The scan mode is a process for determining anti-shake setting information at each position of the imaging range of the imaging device 400. At this time, it is desirable that the display unit 500 is in a state in which it notifies the user that it has been switched to the scan mode. Thereafter, S601 to S606 are repeated until anti-shake setting information is obtained for all imaging ranges that can be imaged by all combinations of rotational positions.

[0050] In S601, the control unit 150 controls the rotation mechanisms 170 and 171 to move to any rotation position within the entire imaging range. The control unit 150 sets the rotation positions in sequence so as to acquire images of the entire imaging range in the scan mode.

[0051] In the next step S602, the imaging unit 410 captures an image at the current rotation position set by the control unit 150. The captured image undergoes predetermined processing in the image processing unit 120 and is sent to the calculation unit 420, and the process proceeds to S603. In S603, the control unit 150 transmits image stabilization setting information (ON / OFF information) of the first image stabilization to the calculation unit 420, and the process proceeds to S604. At this time, the image stabilization setting information of the first image stabilization can be fixed to either the first image stabilization ON or the first image stabilization OFF during scanning.

[0052] In S604, the calculation unit 420 determines whether to perform the first or second stabilization based on the image and stabilization setting information acquired in S602 and S603, and the process proceeds to S605. In this determination, when an image is captured with the first stabilization ON, the second stabilization is performed for the blurred area, and the first stabilization is performed for the unblurred area. In addition, when an image is captured with the first stabilization OFF, the second stabilization is performed for the unblurred area, and the first stabilization is performed for the blurred area. In S605, the selection result of the first or second stabilization determined in S604 is stored in the storage unit 150 as stabilization setting information in association with the current rotation position, and the process proceeds to S606.

[0053] In the next S606, it is determined whether the anti-shake setting values ​​have been stored for all imaging ranges that can be imaged by all combinations of rotation positions. If the anti-shake setting values ​​have been stored for all imaging ranges, the process exits the scan mode and proceeds to S607. If the anti-shake setting values ​​have not been stored for all imaging ranges, the process returns to S601. In S601, in order to continue the scan mode, the control unit 150 sets the rotation mechanisms 170 and 171 to the next rotation position.

[0054] On the other hand, in S607, the processes from S201 to S207 shown in the first embodiment are performed. The processes are as described above with reference to FIG. 2, and therefore will not be described. In this embodiment, as in the first embodiment, the image stabilization setting information stored in the storage unit 160 is overwritten with new information. In this embodiment, when the first image stabilization is selected, the second image stabilization is not performed, so at least one of the detection of image stabilization by the image stabilization detection unit 412 and the processing related to the second image stabilization by the lens unit 411 may be stopped. In addition, when the second image stabilization is selected, the first image stabilization is not performed, so at least one of the detection of image stabilization by the image stabilization detection unit 140 and the control processing of the rotation mechanisms 170 and 171 related to the first image stabilization by the control unit 150 may be stopped.

[0055] In S608, it is determined whether or not a rescan command has been sent from the user. If rescanning is to be performed, the process proceeds to S600 to switch to scan mode, and if rescanning is not to be performed, the process proceeds to S609, where it is determined whether or not imaging is to be ended, as in the first embodiment. If imaging is not to be ended in S609, the process returns to S607, and the processes from S201 to S208 are repeated.

[0056] According to the above, even in an installation environment in which the dominant vibration frequency differs depending on the imaging range and the vibration isolation function used as a countermeasure differs, it is possible to perform vibration isolation processing effectively.
