Description

[Technical field]

[0001] The present invention relates to an imaging apparatus, a control method, a program, and the like. [Background technology]

[0002] In recent years, it has become common to watch videos on vertically long electronic displays such as smartphones and tablet devices. Conventional cameras for video production and PTZ cameras suitable for video distribution over the Internet are products suited to shooting horizontally long videos. Therefore, when using such cameras to shoot vertically long videos (vertical shooting) and distribute them, the video shot with the camera tilted 90 degrees is distributed.

[0003] Non-Patent Document 1 proposes a PTZ camera that shoots by rotating only the camera unit by 90 degrees. It is preferable that when the PTZ camera is rotated by 90 degrees, it can be switched to a vertical shooting mode in which the image is rotated by 90 degrees and distributed.

[0005] However, with conventional technology, there was a problem in that when the imaging device was tilted 90 degrees, users such as the person being photographed and the photographer (including the photography assistant) were unable to recognize whether the shooting mode had been correctly switched to vertical shooting mode.

[0006] The present invention has been made in consideration of the above-mentioned problems, and has an object to enable a user to easily recognize that a shooting mode is in accordance with the attitude of an imaging device. [Means for solving the problem]

[0007] The present invention is characterized in that it is an imaging device having a plurality of tallies, comprising: a detection means for detecting the attitude of the imaging device; and a control means for, when the detection means detects an attitude in which an image to be captured will have a first composition, notifying that the first imaging mode is set using a first tally corresponding to the first imaging mode, and for, when the detection means detects an attitude in which an image to be captured will have a second composition, notifying that the second imaging mode is set using a second tally corresponding to the second imaging mode. Effect of the Invention

[0008] According to the present invention, the user can easily recognize that the shooting mode is appropriate for the attitude of the imaging device. [Brief description of the drawings]

[0010] A preferred embodiment of the present invention will be described below with reference to the drawings. In this embodiment, the imaging device will be described as a PTZ (pan-tilt-zoom) camera 10. The PTZ camera 10 of this embodiment is a network camera, and can take pictures and perform pan and tilt rotations, etc., in response to remote control. The PTZ camera 10 can also distribute the captured video to the outside via a network.

[0011] (First embodiment) Fig. 1 is a perspective view showing an example of the overall configuration of a PTZ camera 10. Fig. 2 is a diagram showing an example of the configuration of the PTZ camera 10 viewed from the front. The PTZ camera 10 includes a fixed base 20, a swivel head 30, and an imaging unit 40.

[0012] The fixed base 20 is a base for installing the PTZ camera 10 at an installation position such as a monitoring location. The PTZ camera 10 can be installed, for example, on a floor, a wall, a ceiling, or a desk. The fixed base 20 of this embodiment has installation sections 21a and 21b (see FIG. 2). The installation section 21a is a section for installing the PTZ camera 10 at an installation position when taking normal photographs (horizontal photographs). The installation section 21a is located on the bottom surface of the fixed base 20. On the other hand, the installation section 21b is a section for installing the PTZ camera 10 at an installation position when taking vertical photographs. The installation section 21b is located on one side surface of the fixed base 20. The installation section 21b has, for example, a 1 / 4 inch screw hole formed therein. Also, the installation surface of the installation section 21b and the installation surface of the installation section 21a are approximately perpendicular to each other.

[0013] The fixed base 20 supports the swivel head 30 by a pan axis rotation holding mechanism including a bearing so that the swivel head 30 can rotate about the pan axis P. The fixed base 20 has various circuit boards for controlling the PTZ camera 10 arranged therein.

[0014] The swivel head 30 supports the imaging unit 40 rotatably around the tilt axis T by a tilt axis rotation and holding mechanism including a bearing. The swivel head 30 also pans (rotates) around a pan axis P relative to the fixed base 20 by a pan motor. When the swivel head 30 pans around the pan axis P, the imaging unit 40 supported by the swivel head 30 also rotates. When the swivel head 30 rotates, the imaging direction of the imaging unit 40 can be set to any azimuth angle.

[0015] The imaging unit 40 is a digital video camera for capturing images. The imaging unit 40 accommodates a lens unit 42, an image sensor board, and the like in a housing 41. Here, the lens unit 42 side in the direction along the optical axis Op (optical axis of the lens unit 42) of the imaging unit 40 is referred to as the front side, and the opposite side is referred to as the back side. The imaging unit 40 of this embodiment has a rectangular shape that is long along the optical axis Op. In addition, the imaging unit 40 tilts and rotates around a tilt axis T relative to the swivel head 30 by a tilt motor. By tilting and rotating the imaging unit 40, the imaging direction of the imaging unit 40 can be set to any elevation angle.

[0016] In the PTZ camera 10, the imaging unit 40, the pan motor, and the tilt motor are driven by power being supplied to the fixed base 20 from an internal battery or from an external source. Furthermore, the PTZ camera 10 receives a control signal in response to remote control from an external controller, thereby controlling the pan motor and tilt motor to change the azimuth angle and the angle of attack of the imaging unit 40. The imaging direction of the imaging unit 40 shown in Figs. 1 and 2 is a reference position (or initial position). Furthermore, the PTZ camera 10 receives a control signal in response to remote control from an external controller, thereby starting imaging by the imaging unit 40, and distributing the captured video via a network.

[0017] The housing 41 of the imaging unit 40 in this embodiment has tallies 50a, 50b for horizontal shooting (normal shooting) and tallies 51a, 51b for vertical shooting. In general, a tally is used to allow users such as the subject and the photographer (including the assistant photographer) to recognize the camera that is used to capture the captured image when multiple cameras are used for shooting. In this embodiment, when multiple cameras are used for streaming, only the tally of the camera used for streaming is lit in a color different from the tallies of the other cameras, allowing the user to recognize the camera that is streaming.

[0018] The horizontal shooting tallies 50a, 50b are provided on a surface that is the upper side of the housing 41 in the reference position when the installation section 21a of the fixed base 20 is installed on a horizontal surface. At least a part of the horizontal shooting tallies 50a, 50b protrudes in a convex shape from the outer shape of the housing 41 (the upper surface of the housing 41), making it easy to view the illuminated light from various angles. The horizontal shooting tally 50a and the horizontal shooting tally 50b are positioned apart in the direction of the optical axis Op. Specifically, the horizontal shooting tally 50a is positioned at an end on the front side of the upper surface of the housing 41, and the horizontal shooting tally 50b is positioned at an end on the rear side of the upper surface of the housing 41. When the imaging unit 40 is viewed from the front, the horizontal shooting tally 50a is disposed on the upper side of the rectangular housing 41 (see FIG. 2). When the imaging unit 40 is viewed from the rear, the horizontal shooting tally 50b is disposed on the upper side of the rectangular housing 41.

[0019] On the other hand, the vertical shooting tallies 51a and 51b are provided on a side surface perpendicular to the upper surface of the housing 41 in the reference position. At least a part of the vertical shooting tallies 51a and 51b protrudes in a convex shape from the outer shape of the housing 41 (the side surface of the housing 41), making it easy to view the illuminated light from various angles. The vertical shooting tally 51a and the vertical shooting tally 51b are positioned apart in the direction of the optical axis Op. Specifically, the vertical shooting tally 51a is positioned at an end of the side of the housing 41 that is on the front side, and the vertical shooting tally 51b is positioned at an end of the side of the housing 41 that is on the rear side. When the imaging unit 40 is viewed from the front, the vertical shooting tally 51a is disposed on a vertical side that is perpendicular to the top side of the rectangular housing 41 (see FIG. 2). When the imaging unit 40 is viewed from the rear, the vertical shooting tally 51b is disposed on a vertical side that is perpendicular to the top side of the rectangular housing 41.

[0020] 1 and 2 show the PTZ camera 10 installed for horizontal shooting, in which the images captured by the camera are landscape format. When the camera is installed for horizontal shooting, the shooting mode becomes horizontal shooting mode (normal shooting mode). While shooting is being performed in horizontal shooting mode, the horizontal shooting tallies 50a and 50b are lit, and the vertical shooting tallies 51a and 51b are turned off. In the horizontal shooting mode, the captured landscape image is distributed in its original orientation. Furthermore, when multiple PTZ cameras are shooting and the PTZ camera 10 is in shooting mode but the video being shot by the PTZ camera 10 is not being distributed, the horizontal shooting tallies 50a, 50b light up green. On the other hand, when the video being shot by the PTZ camera 10 is being distributed, the horizontal shooting tallies 50a, 50b light up red. This allows the user to recognize the PTZ camera being used for distribution. In this way, the horizontal shooting tallies 50a, 50b are tallies that correspond to the horizontal shooting mode.

[0021] Fig. 3 is a diagram showing an example of a state where the PTZ camera 10 is installed for vertical shooting, in which the image captured by the PTZ camera 10 has a vertical composition. Fig. 4 is a perspective view showing an example of a state where the PTZ camera 10 is installed for vertical shooting. Here, as shown in Figs. 3 and 4, the PTZ camera 10 is rotated 90° around the optical axis Op and supported by a support base 80 and installed for vertical shooting. Therefore, the vertical shooting tallies 51a and 51b are located on the surface that becomes the upper side of the housing 41.

[0022] The support base 80 includes a support column 81 , a ball joint 82 , and a support portion 83 . The support pole 81 has a flat and wide contact surface formed at its lower end, and can stably support the PTZ camera 10 even when the PTZ camera 10 is installed. Ball joint 82 connects support column 81 and support section 83 so that support section 83 can be at any inclination angle with respect to support column 81. Therefore, support base 80 functions as a free-angle head by changing the inclination angle of support section 83 with ball joint 82. However, in Figures 3 and 4, ball joint 82 is fixed in a state in which PTZ camera 10 can be installed for vertical shooting.

[0023] The fixed base 20 of the PTZ camera 10 is installed on the support section 83. For example, a ¼ inch screw is provided on the support section 83. In the example shown in Fig. 3, the screw of the support section 83 is screwed into a screw hole of the installation section 21b of the fixed base 20 of the PTZ camera 10 to fix the PTZ camera 10 for vertical shooting. The screw hole of the installation section 21b of the fixed base 20 is located almost directly below the center of gravity of the PTZ camera 10 installed for vertical shooting, so that the support base 80 can stably support the PTZ camera 10 without biasing the weight.

[0024] When the camera is set for vertical shooting, the shooting mode becomes vertical shooting mode. While shooting is being performed in vertical shooting mode, the vertical shooting tallies 51a and 51b are lit, and the horizontal shooting tallies 50a and 50b are turned off. In addition, in vertical shooting mode, the image being shot is rotated 90 degrees and distributed as a vertically long image. Therefore, the viewer of the distributed image can view the image by displaying it on the entire vertical electronic display. Furthermore, when multiple PTZ cameras are shooting and the PTZ camera 10 is in shooting mode but the video shot by the PTZ camera 10 is not being distributed, the vertical shooting tallies 51a and 51b light up in green. On the other hand, when the video shot by the PTZ camera 10 is being distributed, the vertical shooting tallies 51a and 51b light up in red. Therefore, the user can recognize the PTZ camera being used for distribution. In this way, the vertical shooting tallies 51a and 51b are tallies that correspond to the vertical shooting mode.

[0025] 5 is a block diagram showing an example of the configuration of the PTZ camera 10. Note that components already described are given the same reference numerals and description thereof will be omitted. The PTZ camera 10 has a lens drive unit 60, an image sensor 61, horizontal shooting tallies 50a and 50b, vertical shooting tallies 51a and 51b, a pan motor 62, a tilt motor 64, a pan motor driver 63, and a tilt motor driver 65. The PTZ camera 10 also has a posture sensor 66, an antenna 67, a pan / tilt control microcomputer 68, and an imaging control ASIC 69.

[0026] The lens driving unit 60 adjusts the focus by displacing the position of the lens unit 42 based on an instruction from the imaging control ASIC 69. The image sensor 61 converts the formed optical image into an electrical signal. The image sensor 61 can be, for example, an imaging element configured with a CCD or CMOS element. The lens driving unit 60 and the image sensor 61 are housed in the housing 41 of the imaging section 40.

[0027] The pan motor 62 rotates the swivel head 30 about a pan axis P. The pan motor driver 63 drives the pan motor 62 based on an instruction from a microcomputer 68 for pan / tilt control. The tilt motor 64 rotates the imaging unit 40 around a tilt axis T. The tilt motor driver 65 drives the tilt motor 64 based on an instruction from a microcomputer 68 for pan / tilt control.

[0028] The attitude sensor 66 detects the attitude of the PTZ camera 10, and outputs information about the detected attitude to a pan / tilt control microcomputer 68. The attitude sensor 66 may be, for example, an acceleration sensor or a gyro sensor. The antenna 67 transmits and receives data to and from external devices. In this embodiment, the antenna 67 transmits and distributes the video captured by the PTZ camera 10 to an external device via a network.

[0029] The pan-tilt control microcomputer 68 controls the horizontal shooting tallies 50a, 50b, the vertical shooting tallies 51a, 51b, the pan motor driver 63, the tilt motor driver 65, etc. The pan-tilt control microcomputer 68 drives the pan motor 62 and the tilt motor 64 by controlling the pan motor driver 63 and the tilt motor driver 65 based on a control signal from the external controller 70. The pan-tilt control microcomputer 68 also determines the attitude of the PTZ camera 10 based on information detected by the attitude sensor 66. When the pan-tilt control microcomputer 68 determines that the PTZ camera 10 is in an attitude installed for horizontal shooting, it transitions the shooting mode to the horizontal shooting mode and sets it. On the other hand, when it determines that the PTZ camera 10 is in an attitude installed for vertical shooting, it transitions the shooting mode to the vertical shooting mode and sets it. The pan-tilt control microcomputer 68 notifies the imaging control ASIC 69 of information on the set shooting mode.

[0030] When the pan / tilt control microcomputer 68 sets the shooting mode to the vertical shooting mode, it switches the control signals for pan rotation and tilt rotation from the external controller 70. Specifically, when the pan / tilt control microcomputer 68 receives a control signal for changing the azimuth angle from the external controller 70, it controls the tilt motor driver 65 to drive the tilt motor 64, thereby changing the azimuth angle of the imaging unit 40. On the other hand, when the pan / tilt control microcomputer 68 receives a control signal for changing the elevation angle from the external controller 70, it controls the pan motor driver 63 to drive the pan motor 62, thereby changing the elevation angle of the imaging unit 40. Therefore, the operator who operates the external controller 70 can operate the pan rotation and tilt rotation of the PTZ camera 10 with the same feeling as in the horizontal shooting mode.

[0031] The imaging control ASIC 69 controls the lens drive unit 60, the image sensor 61, the antenna 67, etc. The imaging control ASIC 69 performs various image processing on the image output from the image sensor 61. At this time, the imaging control ASIC 69 performs image processing according to the set shooting mode. Specifically, when the shooting mode is a horizontal shooting mode, the imaging control ASIC 69 outputs the image without rotating it. On the other hand, when the shooting mode is a vertical shooting mode, the imaging control ASIC 69 rotates the image by 90 degrees and outputs it. The imaging control ASIC 69 distributes the output image by transmitting it from the antenna 67 via the network.

[0032] Next, the process of the PTZ camera 10 for making the user recognize the shooting mode will be described with reference to the flowchart of Fig. 6. The flowchart of Fig. 6 is started by receiving a control signal for starting shooting from the external controller 70. The flowchart of Fig. 6 is realized by the imaging control ASIC 69 or the pan / tilt control microcomputer 68 executing a program stored in a recording medium. In S 11 , the pan / tilt control microcomputer 68 receives information on the attitude of the PTZ camera 10 detected by the attitude sensor 66 .

[0033] In S12, the pan / tilt control microcomputer 68 judges whether the PTZ camera 10 is in a posture installed for vertical shooting based on the posture information from the posture sensor 66. If the state in which the pan axis P of the PTZ camera 10 is vertical is defined as a tilt angle of 0°, for example, the pan / tilt control microcomputer 68 judges that the PTZ camera 10 is in a posture installed for vertical shooting when the pan axis P of the PTZ camera 10 is at a predetermined angle (e.g., 45°) or more. If it is determined that the PTZ camera 10 is in a posture installed for vertical shooting, the process proceeds to S13. On the other hand, if it is determined that the PTZ camera 10 is not in a posture installed for vertical shooting (if it is determined that the PTZ camera 10 is in a posture installed for horizontal shooting), the process proceeds to S15.

[0034] In S13, the pan / tilt control microcomputer 68 transitions the shooting mode to the vertical shooting mode. In S14, the pan / tilt control microcomputer 68 notifies the user that the shooting mode is the vertical shooting mode by using the tally corresponding to the vertical shooting mode. Specifically, the pan / tilt control microcomputer 68 notifies the user that the shooting mode is the vertical shooting mode by turning on the vertical shooting tallies 51a and 51b and turning off the horizontal shooting tallies 50a and 50b.

[0035] In S15, the pan / tilt control microcomputer 68 transitions the shooting mode to the horizontal shooting mode. In S16, the pan / tilt control microcomputer 68 notifies the user that the shooting mode is the horizontal shooting mode by using the tally corresponding to the horizontal shooting mode. Specifically, the pan / tilt control microcomputer 68 notifies the user that the shooting mode is the horizontal shooting mode by turning on the horizontal shooting tallies 50a and 50b and turning off the vertical shooting tallies 51a and 51b.

[0036] In S17, the pan / tilt control microcomputer 68 judges whether or not a control signal to end shooting has been received from the external controller 70. If a control signal to end shooting has been received, the process of the flowchart in FIG.

[0037] On the other hand, if a control signal to end shooting is not received, the process returns to S11 and the above-mentioned processing is repeated. Therefore, when the PTZ camera 10 is changed from the horizontal shooting setting to the vertical shooting setting, the shooting mode is changed from the horizontal shooting mode to the vertical shooting mode by proceeding from S12 to S13. In this case, the horizontal shooting tallies 50a and 50b are turned off, and the vertical shooting tallies 51a and 51b are turned on instead. Therefore, the user can intuitively recognize that the shooting mode has been changed to the vertical shooting mode, and mistakes in shooting can be prevented.

[0038] Furthermore, when the video captured by the PTZ camera 10 in the vertical shooting mode is not being distributed, the pan / tilt control microcomputer 68 lights up the vertical shooting tallies 51a and 51b in green (first color). On the other hand, when the video captured by the PTZ camera 10 is being distributed, the pan / tilt control microcomputer 68 changes the color of the vertical shooting tallies 51a and 51b to red (second color) and lights them up. In addition, the pan / tilt control microcomputer 68 turns off the horizontal shooting tallies 50a, 50b in the vertical shooting mode. At this time, when some error occurs in the PTZ camera 10, etc., the pan / tilt control microcomputer 68 may notify the error by turning on the horizontal shooting tallies 50a, 50b by flashing them in red or another color (third color).

[0039] Conversely, when the PTZ camera 10 is changed from the vertical shooting setting to the horizontal shooting setting, the shooting mode is changed from the vertical shooting mode to the horizontal shooting mode by proceeding from S12 to S15. In this case, the vertical shooting tallies 51a and 51b are turned off, and the horizontal shooting tallies 50a and 50b are turned on instead. Therefore, the user can intuitively recognize that the shooting mode has been changed to the horizontal shooting mode, and mistakes in shooting can be prevented.

[0040] Furthermore, when the video captured by the PTZ camera 10 in the horizontal shooting mode is not being distributed, the pan / tilt control microcomputer 68 lights the horizontal shooting tallies 50a, 50b in green (first color). On the other hand, when the video captured by the PTZ camera 10 is being distributed, the pan / tilt control microcomputer 68 changes the color of the horizontal shooting tallies 50a, 50b to red (second color) and lights them up. In the horizontal shooting mode, the pan / tilt control microcomputer 68 turns off the vertical shooting tallies 51a and 51b. At this time, when an error occurs in the PTZ camera 10 or the like, the pan / tilt control microcomputer 68 may light up the vertical shooting tallies 51a and 51b by flashing them in red or another color (third color) to notify of the error.

[0041] FIG. 7 is a top view of the PTZ camera 10 when it is installed for vertical shooting using a support stand 80 and the imaging unit 40 is tilted (the azimuth angle is changed). Fig. 7(a) is a diagram showing a state in which the optical axis Op is perpendicular to the pan axis P, and the tilt rotation angle at this time is set to 0°. Fig. 7(b) is a diagram showing a state in which the tilt rotation angle is set to 30° clockwise. Fig. 7(c) is a diagram showing a state in which the tilt rotation angle is set to 50° counterclockwise. Note that the shaded areas shown in Figs. 7(a) to (c) indicate the angle range in which vertical shooting tallies 51a and 51b are visible, and the arrows indicate the front direction.

[0042] As shown in Fig. 7(a) to (c), by installing the PTZ camera 10 for vertical shooting, the vertical shooting tally 51a, 51b is located on the upper side, so that the person U to be photographed can easily see the vertical shooting tally 51a, 51b. In addition, the vertical shooting tally 51a and the vertical shooting tally 51b are located apart in the optical axis Op direction, so that they are not in the shadow of the swivel head 30, and the vertical shooting tally 51a, 51b can be seen from a wide range. Therefore, the person U to be photographed, etc., can easily recognize that the shooting mode has correctly transitioned to the vertical shooting mode by seeing the lighting of the vertical shooting tally 51a, 51b. The state of the PTZ camera 10 shown in Fig. 7(b) shows the same state as the oblique view of Fig. 4, and the user can easily see the vertical shooting tally 51a.

[0043] (Other embodiments) The present invention can also be realized by supplying a program for implementing one or more of the functions of the above-described embodiments to a system or device via a network or a recording medium, and having one or more processors in the computer of the system or device read and execute the program. It can also be realized by a circuit (e.g., ASIC) that implements one or more of the functions.

[0044] The present invention has been described above in detail based on a preferred embodiment thereof, but the present invention is not limited to the specific embodiment, and various forms that do not deviate from the gist of the present invention are also included in the present invention.

[0045] In the above-described embodiment, the imaging device is described as a PTZ camera 10, but the present invention is not limited to this example. The imaging device may be any device that is not capable of pan or tilt rotation as long as it is equipped with an imaging unit. In the above embodiment, the pan / tilt control microcomputer 68 or the imaging control ASIC 69 performs various controls, but this is not limited to the above. The above-mentioned various controls may be performed by one piece of hardware, or the entire device may be controlled by multiple pieces of hardware (e.g., multiple processors or circuits) sharing the processing.

[0046] In the above-described embodiment, the PTZ camera 10 has been described as having two horizontal shooting tallies 50a, 50b, but this is not limited to this case, and the PTZ camera 10 may have one horizontal shooting tally, or three or more horizontal shooting tallies. In the above-described embodiment, the PTZ camera 10 has been described as having two vertical shooting tallies 51a, 51b, but this is not limited to this case, and the PTZ camera 10 may have one vertical shooting tally, or three or more vertical shooting tallies.

[0047] In the above-described embodiment, the horizontal shooting tallies 50a, 50b are turned off in the vertical shooting mode. However, this is not limited to the above case, and the horizontal shooting tallies 50a, 50b may be turned on so as to be less noticeable than the vertical shooting tallies 51a, 51b. In the above-described embodiment, the vertical shooting tallies 51a, 51b are turned off in the horizontal shooting mode. However, this is not limited to the above case, and the vertical shooting tallies 51a, 51b may be turned on so as to be less noticeable than the horizontal shooting tallies 50a, 50b.

[0048] In the above embodiment, the PTZ camera 10 is installed at an angle of 90° for vertical shooting, but vertical shooting can be achieved by a method called cropping. In horizontal shooting mode, the PTZ camera 10 outputs a horizontally long image with an aspect ratio of 16:9. Here, cropping refers to a method of excluding the left and right parts of a 16:9 image and cutting out and outputting a vertically long image with an aspect ratio of 9:16. When the captured image is cropped and distributed, the horizontal shooting tallies 50a and 50b are lit in a color previously assigned for cropping to notify the user. Note that when cropping is used for vertical shooting and distribution, the operation of the external controller 70 is not changed from the horizontal shooting mode.
