Description

[Technical field]

[0001] The present invention relates to an imaging device, and more particularly to an imaging device capable of indicating a subject on which each of a plurality of imaging devices focuses on in a live view (LV). [Background technology]

[0002] Conventionally, there is known a system in which multiple cameras work together to take pictures without missing the shutter chance of the target subject in stadium photography, studio photography, etc. Such a camera linkage system can control the shooting direction, focal length, focus position, shooting timing, etc. of multiple slave imaging devices with a single master imaging device or master control device, and is used in situations where it is required to take many images with a small number of photographers.

[0003] The system described in Patent Document 1 is a system for simultaneously capturing images of specific subjects, in which information on the specific subject detected by a single main imaging device is transferred to a sub imaging device and simultaneous capturing processing is performed. A user of this system can select a subject that the main imaging device and the sub imaging device pay attention to as a specific subject on the LV captured by the main imaging device, and can simultaneously capture images with the main imaging device and the sub imaging device.

[0004] The control device in Patent Document 2 is a control device for photographing a specific subject with a plurality of imaging devices. A user of this control device can select a desired coordinate to be photographed on a map displayed on the control device, select an optimal imaging device for photographing the subject at the desired coordinate, and control the attitude of the imaging device.

[0005] [Patent Document 1] JP 2015-15559 A [Patent Document 2] JP 2012-244511 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, the conventional technology described in Patent Document 1 assumes that the master imaging device and the slave imaging device will capture images of the same subject, and it is not possible to instruct the slave imaging device to capture a specific subject while capturing an image of a different subject with the master imaging device.

[0007] Furthermore, if the conventional technology of Patent Document 2 is used in an imaging device, when issuing an instruction to have the slave imaging device capture a subject other than the specific subject being captured by the main imaging device, the user will take their eyes off the LV image of the main imaging device, which may result in missing a capture opportunity with the main imaging device.

[0008] Therefore, no matter which technique is used, the photographer cannot instruct the slave imaging device to capture an image of another subject without taking his or her eye away from the specific subject being captured by the master imaging device. [Means for solving the problem]

[0009] The imaging device of the present invention is an imaging device capable of communicating with another imaging device, and is characterized in having an imaging element, a display unit that displays an image captured by the imaging element, a designation unit that designates a first subject to be focused on the imaging device and a second subject to be focused on the other imaging device, and a communication unit that transmits position information of the designated second subject to the other imaging device. Effect of the Invention

[0010] According to the imaging device of the present invention, a user can quickly instruct the main imaging device and the slave imaging device on the location of the image to be captured without interrupting image capture by the main imaging device. [Brief description of the drawings]

[0012] As an embodiment of the present invention, a situation is considered in which a first subject is photographed by a camera (handheld camera) held by a user as a main imaging device, and a second subject is photographed by a camera mounted on an unmanned imaging device (drone) as a slave imaging device (another imaging device). The handheld camera and the drone are capable of communicating with each other, and are both operated by a user who operates the handheld camera. The drone receives an instruction to select a subject of interest, and automatically photographs an image to be recorded. Note that, although a drone is taken as an example of the slave imaging device in each embodiment, it may be any imaging device that can freely change photographing parameters such as the photographing direction, angle of view, and aircraft position. Alternatively, it may be a group of slave imaging devices that can photograph an arbitrary position by switching between multiple slave imaging devices.

[0024] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0025] [First embodiment] As a first embodiment, a flow in which a user issues instructions to a handheld camera and a drone to take pictures will be described.

[0026] Fig. 5 is a flow diagram when photographing a first subject with handheld camera 1 and a second subject with drone 3. In this flow, the user operates while switching between handheld camera operation mode and drone operation mode, and can operate each device by using each mode. The initial mode is handheld camera operation mode, in which the user can photograph with the handheld camera and select the first subject, and after the mode switching operation, can select the second subject to focus on with drone 3.

[0027] When the user starts shooting and both the handheld camera 1 and the drone 3 enter shooting mode, it is a start 500. After starting, proceed to step 501 and transition to handheld camera operation mode as the initial state. When the user ends shooting in step 502, it is an end 599. When the user continues shooting in step 502, the handheld camera 1 performs LV image shooting processing 503. The LV image shooting processing includes optical system driving for focus and exposure adjustment, image shooting processing, development processing, etc., which are necessary for LV image shooting. In step 504, the LV image 600 shot in step 503 and various information 604 are displayed on the display 101, and the process proceeds to step 505. An example of the display displayed on the display of the handheld camera 1 in step 504 is shown in FIG. 6(a). In FIG. 6, 600 indicates an LV image, 601 indicates a first subject, 602 indicates a second subject, 604 indicates various information, 611 and 621 indicate a subject selection frame, and 612 and 622 indicate a subject attention frame. In this embodiment, the subject selection frame 611 and the subject attention frame 612 are used to select and focus on a first subject to be photographed by the handheld camera 1, and the subject selection frame 621 and the subject attention frame 622 are used to select and focus on a second subject to be photographed by the drone 3. The subject selection frames 611 and 621 are icons such as squares displayed to allow the user to specify the coordinates of the subject to be focused on, and may not be in the form of a frame. The subject selection frames 611 and 621 are initially displayed at any coordinates on the LV image. The subject attention frames 612 and 622 are icons such as squares displayed to present the subject to be focused on by the handheld camera or drone to the user, and may not be in the form of a frame, and may be of a different color or shape from the subject selection frame. The area surrounded by the subject attention frames 612 and 622 may be the entire area of ​​the specified subject, or may be an area of ​​an organ such as a face or eye of a living organism detected by a known method, or an area having other specific features. The subject attention frames 612 and 622 are displayed on the subjects designated in the handheld camera operation mode and the drone operation mode, respectively. Therefore, multiple subject attention frames may be displayed on the LV image.

[0028] The various information 604 includes shooting mode information, shooting parameters, exposure information such as histograms, information on the device status, communication information, etc. The shooting mode information includes exposure control, focus control, continuous shooting, still images, videos, etc. The information includes aperture, focus position, focal length, sensitivity, color, image size, etc. The information on the device status includes the device position, speed, acceleration, inclination, power supply, number of shots that can be taken, etc.

[0029] In step 505, it is determined whether or not there has been a movement operation of the subject selection frames 611 and 621. The movement operation of the subject selection frames 611 and 621 is performed by tilting the joystick 102 of the handheld camera 1, pressing the cross key 103, touching the touch panel 101, or the like. If there has been a movement operation of the subject selection frame 602, the process proceeds to step 506, and if there has been no movement operation of the subject selection frames 611 and 621, the process proceeds to step 508. If there has been a movement operation of the subject selection frames 611 and 621, the coordinates of the subject selection frame of the device being operated are updated in step 506, and in step 507, the subject attention frames 612 and 622 of the device being operated are erased, and the subject selection frames 611 and 621 of the device being operated are displayed. In the case of the handheld camera operation mode, the subject selection frame 611 is displayed, and in the case of the drone operation mode, the subject selection frame 621 is displayed.

[0030] Then, in step 508, it is determined whether or not the release button has been pressed halfway. If the release button has not been pressed halfway, the process returns to step 502, and if the release button has been pressed halfway, the process proceeds to step 509. In step 509, the subject detection unit 214 of the handheld camera 1 sets a subject at the same or nearby coordinates as the subject selection frame as a subject of interest. If the operating mode is the handheld camera operation mode, the subject is set as a subject of interest for the handheld camera, and if the operating mode is the drone operation mode, the subject is set as a subject of interest for the drone. At this time, the subject position calculation unit 218 calculates the position of the subject.

[0031] Then, in step 510, it is determined whether or not the mode is a handheld camera operation mode. If the mode is a handheld camera operation mode, the coordinates of the subject calculated by the subject position calculation unit 218 are used to perform a subject attention operation on the subject of interest in step 511. The subject attention operation includes automatic control of focus and exposure (AF, AE). If the mode is not a handheld camera operation mode in step 510, the coordinates of the subject calculated by the subject position calculation unit 218 are transferred to the drone 3 in step 12. In response to this, in step 513, the drone 3 performs a subject attention operation on the subject of interest. The drone 3 detects the subject of interest with the subject detection unit 414 while focusing on the subject, and transfers the coordinates of the subject calculated by the subject position calculation unit 418 to the handheld camera 1. The subject attention operation of the drone 3 includes AF, AE, automatic shooting, control of the gimbal 203, and aircraft control. Then, in step 514, the subject coordinates on the image are calculated by a known method from the subject position calculated by the subject position calculation unit 218 or the subject position transferred by the drone 3, and the coordinates of the information subject attention frame are updated. Then, in step 515, the subject selection frames 611 and 621 are erased, and subject focus frames 612 and 622 are displayed so as to surround the focus subject. An example of the display in step 515 is shown in FIG. 6(b). FIG. 6(b) shows a screen display in which the first subject is being focused on by the hand-held camera 1, and the processing of step 515 is performed in the state of FIG. 6(a). Then, in step 516, it is determined whether or not a mode switching operation has been performed. A mode switching operation is the pressing of any button on the hand-held camera 1 or the switching of a switch. If a mode switching operation has not been performed, the process proceeds to step 517, and if a mode switching operation has been performed, the process proceeds to step 519. If a mode switching operation has not been performed in step 516, it is determined in step 517 whether or not the release button has been fully pressed. If the release button has been fully pressed, a recording image shooting process is performed in step 518, and if the release button has not been fully pressed, the process returns to step 502. The recording image capture process in step 518 includes optical system drive for focus and exposure adjustment, imaging process, development process, encoding process, recording process, etc., which are necessary for recording image capture. When step 518 is completed, the process returns to step 502.If a mode switching operation is performed in step 516, it is determined whether or not the operating mode is a handheld camera operation mode in step 519. If the operating mode is the handheld camera operation mode, the mode transitions to the drone operation mode in step 520. If the operating mode is not the handheld camera operation mode, the mode transitions to the handheld camera operation mode in step 521. Then, the process returns to step 502.

[0032] After the mode switching operation is performed while the handheld camera 1 is focusing on the first subject and the mode is switched to the drone operation mode, when the focus subject is set in step 509, each of the handheld camera 1 and the drone 3 has a focus subject. At this time, a plurality of subject selection frames or subject focus frames are displayed on the display 101 of the handheld camera 1. FIG. 6(c) shows a screen display when the mode is switched to the drone operation mode while the handheld camera 1 is focusing on the first subject, and a subject to be focused on by the drone 3 is selected in the subject selection frame 621. As shown in FIG. 6(c), the user can specify a second subject to be focused on by the drone on the LV screen while focusing on the first subject with the handheld camera. FIG. 6(d) shows a screen display when the handheld camera 1 is focusing on the first subject and the drone 3 is focusing on the second subject, and the processing of step 515 is performed in the state of FIG. 6(c).

[0033] As described above, by using the imaging device of this embodiment, a user can select a second subject to be focused on and photographed by a drone while photographing a first subject with a handheld camera. Since the user can select the second subject without taking his / her eyes off the first subject in the LV image, the possibility of missing an opportunity to photograph the first subject can be reduced, and any second subject can be photographed by the drone. This concludes the description of the first embodiment.

[0034] [Second embodiment] The second embodiment is substantially similar to the first embodiment, and the configurations of the handheld camera and drone are also similar, and correspond directly to Figures 1, 2, 3, and 4. In this specification, only the parts that differ from the first embodiment will be described.

[0035] This embodiment differs from the first embodiment in the types of instructions and the method of issuing instructions to the drone when in drone operation mode. In addition to selecting the subject that the drone will photograph, the user can also instruct the drone from which direction to photograph the subject.

[0036] Fig. 7 is a flow diagram of the processing of this embodiment. In Fig. 7, start 700 to step 706, step 708 to step 711, step 713 to step 721, and end 799 are the same as Fig. 5 of the first embodiment. In this embodiment, during LV display operation, steps 731 to 735 for instructing the shooting direction of the subject are inserted after step 706. Also, the data transferred from the handheld camera to the drone in step 712 is different.

[0037] After step 706, or if there is no movement operation of the subject selection frame in step 705, proceed to step 731. In step 731, it is determined whether or not the operating mode is a handheld camera operation mode. If the operating mode is not a handheld camera operation mode, proceed to step 732. In step 732, it is determined whether or not there is a subject shooting direction selection operation. The subject shooting direction selection operation is performed by rotating the dial 104 or by operating the touch panel 101, but may be performed by other operations. If there is no subject shooting direction selection operation in step 732, proceed to step 708. If there is a subject shooting direction selection operation, proceed to step 733. In step 733, the subject shooting direction is updated according to the subject shooting direction selection operation in step 732. Thereafter, in step 734, the subject attention frame for the drone is erased, and the subject selection frame for the drone and the subject shooting direction are displayed. When the processing of step 734 is completed, proceed to step 708.

[0038] FIG. 8 shows an example of the display displayed on the display of the handheld camera 1 in step 734. In FIG. 8, 821 indicates a subject selection frame, 812 and 822 indicate subject attention frames, and 831 and 832 indicate the subject shooting direction. In this embodiment, the subject attention frame 812 is used to focus on the first subject to be photographed by the handheld camera 1, and the subject selection frame 821 and the subject attention frame 822 are used to select and focus on the second subject to be photographed by the drone 3. The subject selection frame 821 is an icon such as a circle displayed to allow the user to specify the coordinates of the subject to be focused on, and may not be in the form of a frame. The subject selection frame 821 is initially displayed at any coordinates on the LV image. The subject attention frames 812 and 822 are icons such as a circle displayed to present the subject to be focused on by the handheld camera or drone to the user, and may not be in the form of a frame, and may be in a color or form different from the subject selection frame. The subject shooting direction display 831 is an icon such as a sector, and is displayed by rotating around the center of the subject selection frame in accordance with the subject shooting direction selection operation in step 732. For example, the subject shooting direction display 831 in FIG. 8(a) indicates that the drone will shoot the subject from the front (the side of the photographer using the handheld camera), and in FIG. 8(b) indicates that the drone will shoot the subject from the right side (the right side of the photographer using the handheld camera). The subject shooting direction display 832 is an icon such as a sector, and may be a different color or shape from the subject shooting direction display 831.

[0039] In step 731, if the operating mode is the hand-held camera operation mode, the process proceeds to step 735. In step 735, the subject attention frame for the hand-held camera is erased, and a subject selection frame for the hand-held camera is displayed. When step 735 is completed, the process proceeds to step 708.

[0040] In step 712, unlike the first embodiment, the handheld camera transfers the coordinates and shooting direction of the subject of interest to the drone.

[0041] As described above, by using the imaging device of this embodiment, the user can select a second subject in the LV image without taking his / her eyes off the first subject, and can have the drone capture the second subject from any direction. Therefore, in addition to the effects of the first embodiment, the captured image of the second subject can be more closely matched to the user's request. This concludes the description of the second embodiment.

[0042] [Third embodiment] The third embodiment is substantially similar to the first embodiment, and the configurations of the handheld camera and drone are also similar, and correspond directly to Figures 1, 2, 3, and 4. In this specification, only the parts that differ from the first embodiment will be described.

[0043] The difference between the present embodiment and the first embodiment is that the image captured by the drone is used for the LV of the handheld camera. In the drone operation mode, the user can select a subject outside the shooting angle of the handheld camera as the second subject for the drone to focus on.

[0044] Fig. 9 is a flow diagram of the process of this embodiment. In Fig. 9, start 900 to step 904, step 905 to step 921, and end 999 are the same as Fig. 5 of the first embodiment. In this embodiment, steps 951 to 953 for displaying an LV image of the drone are inserted after step 904 during the LV display operation.

[0045] When step 904 is completed, the process proceeds to step 951. In step 904, examples of display on the display of the handheld camera 1 are shown in FIG. 10(a)(b). In step 951, it is determined whether or not there is a subject selection frame or a subject attention frame whose coordinates are outside the screen. If there is a subject selection frame or a subject attention frame whose coordinates are outside the screen, the process proceeds to step 952. In step 952, an LV image captured by the drone is received from the drone, and in step 953, the LV image of the drone is displayed. It is assumed that the LV image of the drone to be displayed is a part of the subject selection frame of the captured image that is cut out and displayed, but the entire captured image may be displayed. In addition, the image to be displayed may be cut out according to the characteristics of the subject, such as the face or body area of ​​a living thing. In addition, the position of the LV image of the drone to be displayed may be changed depending on the coordinates of the subject selection frame or the subject attention frame. In step 953, examples of display on the display of the handheld camera 1 are shown in FIG. 10(c), (d), and (e). FIG. 10(c), (d), and (e) are diagrams showing a scene in which a second subject outside the LV screen of a handheld camera is selected using a drone subject selection frame. In FIG. 10, 1000 is an LV image taken by a drone, 1002 is a second subject on the LV of the drone, and 1003 is an LV image taken by the drone in which the face part of the second subject is cut out. 1021 is a drone subject selection frame superimposed on the LV of the drone, and 1022 is a drone subject attention frame superimposed on the LV of the drone. The subject selection frame 1021 is an icon such as a square displayed to allow the user to specify the coordinates of the subject of interest, and may not be in the form of a frame. The subject selection frame 1021 is initially displayed at any coordinates on the LV image. The subject attention frame 1022 is an icon such as a square displayed to present the subject of interest to the user, and may not be in the form of a frame, and may be in a color or form different from that of the subject selection frame. 10(c) shows the LV of the drone superimposed on the upper right area of ​​the LV of the handheld camera, and displays a subject selection frame 1021 within the LV of the drone. If a subject selection frame movement operation is performed in step 905, the LV area of ​​the drone that is displayed is changed by adjusting the shooting direction of the drone and the cropping area accordingly.FIG. 10(d) is an example in which the LV of the drone to be displayed in a superimposed manner is cut out to match the face of the second subject and displayed. If there is a subject selection frame movement operation in step 905, the faces of multiple subjects may be displayed in sequence as the second subject. FIG. 10(e) is an example in which the display position of the LV of the drone to be displayed in a superimposed manner is changed according to the coordinates of the drone subject selection frame. If there is a subject selection frame movement operation in step 905, the display position of the LV of the drone is also changed according to this. When step 953 is completed, proceed to step 905. If there is no subject selection frame or subject attention frame whose coordinates are outside the screen in step 951, proceed directly to step 905.

[0046] FIG. 10(f) shows an example of the display on the display of the handheld camera 1 in step 915. FIG. 10(f) shows a scene in which a second subject outside the LV screen of the handheld camera is displayed in a drone subject attention frame. In this case, the LV of the drone to be superimposed on the LV of the handheld camera may be cut out according to the characteristics of the subject, such as the face or body area of ​​a living creature, as shown in FIG. 10(d). Also, as shown in FIG. 10(e), the position at which the LV of the drone is superimposed may be changed. When changing the position at which the LV of the drone is superimposed while focusing on the second subject, the position at which the LV is superimposed may be changed according to the position of the second subject.

[0047] As described above, by using the imaging device of this embodiment, the user can select a second subject outside the shooting angle of the handheld camera without taking his / her eyes off the first subject in the LV image, and have the drone shoot the second subject. Therefore, in addition to the effect of the first embodiment, it is possible to instruct the drone to shoot a wider range of subjects. This concludes the description of the third embodiment.
