Description

[Technical Field]

[0001] This relates to an imaging device. [Background technology]

[0002] In recent years, from the viewpoint of ensuring privacy, there has been a demand for an imaging device that clearly indicates that imaging is not possible when not imaging. In conventional imaging devices, the imaging direction of the imaging unit can be rotated in a pan direction / tilt direction, and the imaging direction when not imaging is rotated outside the imaging range when imaging (in the direction of gravity, for example). This clearly indicates to the user or the subject that imaging is not possible (at least within the imaging range when imaging).

[0003] Incidentally, Patent Document 1 discloses an imaging device that includes a first imaging unit that can rotate in the pan / tilt direction, and a second imaging unit that has a wider angle than the first imaging unit and does not rotate in the pan / tilt direction.

[0004] In the case of the imaging device described in Patent Document 1, even if the imaging direction during non-imaging is rotated outside the imaging range during imaging, the second imaging unit does not rotate, so it still appears to the user that imaging by the second imaging unit is possible.

[0010] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The embodiments described below are examples of means for realizing the present invention, and should be appropriately modified or changed depending on the configuration of the device to which the present invention is applied and various conditions. The present invention is not limited to the following embodiments. Furthermore, a configuration may be made by appropriately combining parts of each embodiment described below.

[0011] First Embodiment (Device configuration) 1 is a perspective view of an imaging device according to this embodiment. The imaging device according to this embodiment is composed of a first imaging unit 1, a support unit 2, a base unit 3, and a second imaging unit 4. The first imaging unit 1 is supported by the support unit 2, which has a built-in tilt drive unit (not shown). The first imaging unit 1 rotates in the tilt direction when driven by the tilt drive unit (not shown).

[0012] The support unit 2 is supported by a base unit 3, and the base unit 3 has a built-in pan drive unit (not shown). The support unit 2 rotates in the pan direction when driven by the pan drive unit (not shown). The tilt drive unit and pan drive unit are motors or the like that operate when power is supplied, and serve as a power source for rotating the first imaging unit 1 in the pan direction or in the pan direction.

[0013] The base 3 has a second imaging unit 4 on an arcuate surface 5. The second imaging unit 4 is a wide-angle camera unit having a wider angle of view than the first imaging unit 1. The second imaging unit 4 is fixed to the base 3 and is provided at a position where it cannot be rotated by the tilt driving unit and pan driving unit described above.

[0014] 2 and 3 are exploded views of the imaging device according to this embodiment. The first imaging unit 1 is composed of an imaging main body 6 and a shaft 7. The imaging main body 6 has a built-in imaging sensor for taking pictures and a lens unit 8. The shaft 7 is provided on a side surface 9 and a side surface 10 of the imaging main body 6. The shaft 7 extends in a substantially vertical direction from the side surface 9 and a side surface 10 and is supported by the support unit 2.

[0015] The support part 2 is composed of a bottom part 11 and a holding part 12, and the holding part 12 extends vertically from the bottom part 11 and supports the first imaging part 1 by holding the shaft part 7 of the first imaging part 1.

[0016] Of the holding part 12 and the bottom part 11, a tilt drive part is built into the holding part 12, and the tilt drive part rotates the shaft part 7, thereby rotating the first imaging part 1.

[0017] A shielding portion 14 is provided on the exterior portion 13 of the support portion 2. The shielding portion 14 extends from the bottom portion 11 toward the base portion 3 along the arc surface of the exterior portion 13. The shielding portion 14 is also provided so as to cover a portion of the arc surface 5 of the base portion 3. As the support portion 2 rotates in the pan direction, the exterior portion 13 of the support portion 2 and the extended shielding portion 14 also rotate in the pan direction, and the shielding portion 14 moves so as to slide along the arc surface 5 of the base portion 3.

[0018] The support part 2 is attached to the top surface 24 of the upper part of the base part 3. The bottom back surface 15, which faces the top surface 24 of the upper part, has a shaft part 16. The shaft part 16 extends in a substantially vertical direction from the bottom back surface 15 and passes through a through-hole 20 of the base part 3. As mentioned above, the base part 3 has a built-in pan drive part (not shown), and when the pan drive part (not shown) rotates the shaft part 16, the support part 2 rotates in the pan direction.

[0019] 4 and 5 are exploded views of the base 3. The base 3 is composed of a base main body 17, an imaging unit 18, and a bottom cover 19. The base main body 17 is a block component having an internal space. The base main body 17 has an upper stage 22 having an arcuate surface 5 located inside an exterior surface 21. The upper stage 22 has an upper stage top surface 24 that is closer to the first imaging unit 1 than a middle stage top surface 23 of the base main body 17. The upper stage top surface 24 has a through hole 20 that connects to the internal space of the base main body 17. The aforementioned shaft 16 passes through the through hole 20.

[0020] The arc surface 5 of the upper section 22 is located inside the exterior section 13 of the support section 2 described above. The arc surface 5 also has an exposure hole 25 that exposes the second imaging section 4 (described later) to the outside. The imaging unit section 18 equipped with the second imaging section 4 is attached to the top surface 26 of the base section 3.

[0021] The imaging unit 18 is composed of the second imaging unit 4 and a sheet metal part 27. The sheet metal part 27 has a plurality of mounting holes 28 for mounting to the base main body 17. The sheet metal part 27 is fixed with screws into screw holes 29 in the base main body 17 via the mounting holes 28. The sheet metal part 27 also has a through hole 30 through which the shaft 16 of the support part 2 passes. The sheet metal part 27 also has a bent part 31 at its end. The second imaging unit 4 is fixed with screws to the bent part 31.

[0022] The second imaging unit 4 is equipped with an imaging sensor for wide-angle imaging and a lens unit 32. The second imaging unit 4 has a wider angle of view than the first imaging unit 1. Therefore, the image captured by the second imaging unit 4 captures position information of the subject over a wider range than the image captured by the first imaging unit 1. By utilizing the position information of the subject, the first imaging unit 1 can manually or automatically track the subject without losing sight of it. As described above, the lens unit 32 of the second imaging unit 4 is exposed to the outside through the exposure hole 25 provided in the arc surface 5 of the base unit 3.

[0023] The bottom surface 34 of the base 3 has an opening 33 that connects to the internal space. The bottom lid 19 is attached to the bottom surface 34. With the above configuration, after the imaging unit 18 is fixed by screws, the opening 33 can be closed with the bottom lid 19.

[0024] (Method for indicating that each imaging unit is in a non-imaging state) Below, we will explain that the imaging device of this embodiment has a mode in which the lens unit 8 of the first imaging unit 1 and the lens unit 32 of the second imaging unit 4 are hidden from the surroundings, thereby clearly indicating to the surroundings that imaging is not possible.

[0025] The imaging device according to this embodiment has a shooting mode (first mode) indicating a shooting possible state, and a security mode (second mode) indicating a shooting impossible state to those around. Fig. 6 is a perspective view showing the imaging device in the shooting mode, and Fig. 7 is a perspective view showing the imaging device in the security mode.

[0026] In the shooting mode, the first imaging unit 1 exposes the lens unit 8 to the outside for shooting. Similarly, the second imaging unit 4 exposes the lens unit 32 to the outside for shooting. At this time, at least a part of the range imaged by the first imaging unit 1 and the range imaged by the second imaging unit 4 overlap. Note that the range imaged by each imaging unit in the shooting mode can be set arbitrarily by the user. Depending on the design of the imaging device, there may be a physical limit to the angle at which it can be rotated. In such a case, the user's setting is reflected within a range that does not exceed the physical limit.

[0027] When switching from the photography mode to the security mode, the first imaging unit 1 is rotated in the tilt direction so that the rotation angle in the tilt direction is greater than or less than a predetermined angle. Here, we will explain what the predetermined angle is. The first is a rotation angle at which the field of view of the first imaging unit 1 and the field of view of the second imaging unit 4 do not overlap. Since there is no unique angle at which the field of view of the first imaging unit 1 and the field of view of the second imaging unit 4 do not overlap, the minimum rotation angle among the possible rotation angles is preferably set as the predetermined angle. For example, consider a case where the angle at which the optical axis is parallel to the installation surface of the imaging device is set to 0°, and the possible rotation angle in the tilt direction is set to [-90°, 90°]. For example, if the rotation angle range where the field of view of the first imaging unit 1 and the field of view of the second imaging unit 4 overlap is [-45°, 45°] and the resolution of the tilt drive unit is in 5° units, the possible rotation angles are [-90, -50°] and [50°, 90°]. In this case, the predetermined angle is set to either -50° or 50°, and the tilt drive unit is controlled so that the rotation angle in the tilt direction is -50° or less or 50° or more when switching to security mode.

[0028] The second is the approximate upper limit of the angle at which the first imaging unit can be rotated. Similarly to the above, if the rotatable angle in the tilt direction is set to [-90°, 90°], the predetermined angle is set to either -90° or 90°. When switching to security mode, the tilt drive unit is controlled so that the rotation angle in the tilt direction is approximately -90° or less or approximately 90° or more. Because the rotatable angle in the tilt direction is set to [-90°, 90°], the rotation angle in the tilt direction is inevitably -90° or 90°. Preferably, as shown in FIG. 7, the rotation angle is set to -90°, and the lens unit 8 of the first imaging unit 1 is completely shielded by the bottom 11 of the support unit 2.

[0029] Therefore, the predetermined angle is at least an angle at which the range (field of view) imaged by the first imaging unit 1 and the range (field of view) imaged by the second imaging unit 4 do not overlap.

[0030] As mentioned above, since the rotation angle set by the user may differ from the rotation angle due to physical constraints, the angle may be set to less than -90° or greater than 90° in security mode. For example, if the range of rotation angles set by the user is smaller than the range of rotation angles at which the field of view of the first imaging unit 1 and the field of view of the second imaging unit 4 overlap, the angle should be set to a larger / smaller angle than the set rotation angle. This is because it is impossible to rotate the first imaging unit 1 so that the field of view of the first imaging unit 1 and the field of view of the second imaging unit 4 do not overlap within the angle range set by the user.

[0031] As described above, when switching from the photography mode to the security mode, the first imaging unit 1 is rotated in the tilt direction so that the rotation angle in the tilt direction is equal to or greater than a predetermined angle. In other words, the first imaging unit 1 is rotated in the tilt direction so that the absolute value of the rotation angle in the tilt direction is equal to or greater than a predetermined angle. In the security mode, the first imaging unit 1 is rotated so as to fall outside the range that can be captured by the first imaging unit 1 in the photography mode, which indicates to the user or the subject that the first imaging unit 1 is in a non-imaging state.

[0032] Although the case where the first imaging unit 1 is rotated in the tilt direction in the security mode has been described, the same concept is used to control the case where the support unit 2 is rotated in the pan direction. That is, in the security mode, the support unit 2 is rotated in the pan direction so that the rotation angle in the pan direction is equal to or greater than a predetermined angle (the absolute value of the rotation angle is equal to or greater than a predetermined angle). The support unit 2 can be rotated in the pan direction so that it is outside the range that can be captured by the first imaging unit 1 in the shooting mode.

[0033] Therefore, when the support part 2 rotates in the pan direction to a position where the field of view of the first imaging part 1 does not overlap with the field of view of the second imaging part 4, the rotation angle of the support part 2 reaches outside the range of rotation possible in the pan direction in the shooting mode.

[0034] So far, we have explained an example of notifying a user or a subject that the first imaging unit 1 is in a non-imaging state in security mode. Next, we will explain an example of notifying a user or a subject that the second imaging unit 4 is in a non-imaging state.

[0035] The imaging device according to this embodiment is configured so that when the rotation angle in the pan direction is equal to or greater than a predetermined angle (the absolute value of the rotation angle is equal to or greater than the predetermined angle), the second imaging unit 4 is shielded by the shielding unit 14. As shown in FIG. 7 , the second imaging unit 4 fixed to the base unit 3 is shielded by the shielding unit 14.

[0036] Since the shielding portion 14 is formed by extending a portion of the support portion 2 onto the base portion 3, when the support portion 2 rotates in the pan direction, the shielding portion 14 also moves. Therefore, the size of the shielding portion 14 is adjusted so that when the support portion 2 rotates in the pan direction to an angle equal to or greater than a predetermined angle, the shielding portion 14 moves to a position where it shields the second imaging unit 4. In other words, the range that the shielding portion 14 covers on the circumferential surface of the base portion 3 to which the second imaging unit 4 is fixed is adjusted.

[0037] By adjusting the range that the shielding part 14 covers on the circumferential surface of the base part 3, it is possible to determine the angle at which the second imaging part 4 is shielded by the rotation angle of the support part 2 in the pan direction.

[0038] Therefore, the size of the shielding part 14 is designed so that when the rotation angle of the support part 2 in the pan direction becomes equal to or less than a predetermined angle, the shielding part 14 shields the second imaging part 4. The predetermined angle is an angle at which the fields of view of the first imaging part 1 and the second imaging part 4 do not overlap, so when the security mode is switched to and the support part 2 rotates equal to or less than the predetermined angle, the shielding part 14 shields the second imaging part 4.

[0039] In this way, in the security mode, the second imaging unit 4 is shielded by the shielding unit 14, and therefore it is indicated to the user or the subject that the second imaging unit 4 is in a non-imaging state. Furthermore, it is indicated that the first imaging unit 1 is in a non-imaging state, and at the same time, it is indicated that the second imaging unit 4 is in a non-imaging state.

[0040] As described above, the imaging device according to this embodiment can indicate that both the first imaging unit 1 and the second imaging unit 4 are in a non-imaging state when not capturing images.

[0041] <Second embodiment> An imaging device according to this embodiment will be described. FIG. 8 is a perspective view of the imaging device according to this embodiment. The imaging device according to this embodiment is composed of a first imaging unit 51, a support unit 52, a base unit 53, and a second imaging unit 54. The first imaging unit 51 is supported at both ends by the support unit 52. The support unit 52 has a built-in tilt drive unit (not shown). Operation of the tilt drive unit (not shown) causes the first imaging unit 51 to rotate in a tilt direction relative to the support unit 52. The support unit 52 is supported by the base unit 53. The base unit 53 has a built-in pan drive unit (not shown). Operation of the pan drive unit (not shown) causes the support unit 52 to rotate in a pan direction relative to the base unit 53. The base unit 53 has a second imaging unit 54 on an exterior surface 72, which will be described later. The second imaging unit 54 is a wide-angle camera unit with a wider angle of view than the first imaging unit 51.

[0042] 9 and 10 are exploded views of the imaging device according to this embodiment. The first imaging unit 51 is composed of an imaging main body 56, a shaft 57, and a lens hood 58. The imaging main body 56 houses an imaging sensor and a lens for photographing, and has a lens unit 59. The lens hood 58 is attached to the lens unit 59. The lens hood 58 has a protrusion 60 that protrudes forward at its upper part, and serves to block unnecessary external light and reduce its effect on the captured image when light from lighting or the sun shines mainly from above.

[0043] Furthermore, a shaft portion 57 is provided on a side surface 61 and a side surface 62 of the imaging main body portion 56. The shaft portion 57 extends vertically from the side surface 61 and the side surface 62, and is supported by the support portion 52 at both ends.

[0044] The support unit 52 is a block component made up of a bottom portion 63 and a holding portion 64. The holding portion 64 extends vertically from the bottom portion 63 and supports the shaft portion 57 of the first imaging unit 51 at both ends, as described above. The holding portion 64 also incorporates a tilt drive unit (not shown), as described above. The tilt drive unit (not shown) rotates the shaft portion 57, causing the first imaging unit 51 to rotate in the tilt direction relative to the support unit 52.

[0045] The support part 52 is attached to a top surface 65 of the base part 53, which will be described later. A bottom back surface 66 facing the top surface 65 has a shaft part 67. The shaft part 67 extends vertically from the bottom back surface 66 and passes through a through-hole 68 of the base part 53, which will be described later. The base part 53 has a built-in pan drive part (not shown), as described above. When the pan drive part (not shown) rotates the shaft part 67, the support part 52 rotates in the pan direction relative to the base part 53.

[0046] 11 and 12 are exploded views of the base 53. The base 53 is composed of a base main body 69, an imaging unit 70, and a bottom cover 71. The base main body 69 is a block component with an internal space. The top surface 65 of the base main body 69 has a through-hole 68 that communicates with the internal space of the base main body 69. The aforementioned shaft 67 passes through the through-hole 68.

[0047] Additionally, the exterior surface 72 of the base main body 69 is provided with an exposure hole 73 that exposes the second imaging unit 54 (described later) to the outside.

[0048] The imaging unit 70 equipped with the second imaging unit 54 is attached to the top surface 74 of the base main body 69. The imaging unit 70 is composed of the second imaging unit 54 and a sheet metal part 75. The sheet metal part 75 has a plurality of mounting holes 76 for mounting to the base main body 69. The sheet metal part 75 is fixed to the base main body 69 with screws via the mounting holes 76 into screw holes 77 in the base main body 69.

[0049] The sheet metal part 75 also has a through hole 78 through which the shaft part 67 of the support part 52 passes. The sheet metal part 75 also has a bent part 79 at its end. The second imaging part 54 is fixed to the bent part 79 with a screw.

[0050] The second imaging unit 54 is equipped with an imaging sensor and a lens for wide-angle imaging. Furthermore, the second imaging unit 54 has a wider angle of view than the first imaging unit 51. Therefore, the image captured by the second imaging unit 54 captures position information of the subject over a wider range than the image captured by the first imaging unit 51. By utilizing the position information of the subject, the first imaging unit 51 can manually or automatically track the subject without losing sight of it. Furthermore, the lens unit 80 of the second imaging unit 54 is exposed to the outside through the exposure hole 73 provided in the exterior surface 72 of the base unit 53, as described above.

[0051] The bottom surface 81 of the base 53 has an opening 82 that connects to the internal space. The bottom lid 71 is attached to the bottom surface 81. With the above configuration, the opening 82 can be closed with the bottom lid 71 after the imaging unit 70 is fixed by screws.

[0052] Below, we will explain that the imaging device of this embodiment has a mode in which the lens unit 59 of the first imaging unit 51 and the lens unit 80 of the second imaging unit 54 are hidden from the surroundings, thereby clearly indicating to the surroundings that the device is in a non-imaging state.

[0053] The imaging device according to this embodiment has a shooting mode that indicates a state in which imaging is possible when powered on, and a security mode that indicates a non-imaging state to those around it. Fig. 13 is a perspective view showing the imaging device in the shooting mode, and Fig. 14 is a perspective view showing the imaging device in the security mode.

[0054] In the photographing mode, the lens section 59 of the first image pickup section 51 is exposed to the outside for photographing, and the lens section 80 of the second image pickup section 54 is also exposed to the outside for photographing.

[0055] When switching from the photography mode to the security mode, the first imaging unit 51 rotates in the tilt direction to a position where its angle of view does not overlap with the angle of view of the second imaging unit 54. The rotation in the tilt direction causes the rotation angle of the first imaging unit 51 to fall outside the range of angles that can be rotated in the tilt direction during photography. The rotation in the tilt direction causes the lens unit 59 of the first imaging unit 51 to be shielded by the bottom part 63 of the support part 52.

[0056] Furthermore, due to the rotation in the tilt direction, the protrusion 60 of the lens hood portion 58 of the first imaging unit 51 moves to a position covering the lens portion 80 of the second imaging unit 54. Therefore, the lens portion 80 of the second imaging unit 4 is shielded by the lens hood portion 58. In the imaging device according to the first embodiment, the shielding portion 14 moves in accordance with the rotation of the support portion 2 in the pan direction. On the other hand, in the imaging device according to the present embodiment, the lens hood portion 58, which is the shielding portion, moves in accordance with the rotation of the first imaging unit 1 in the tilt direction. As a result, when the rotation angle in the tilt direction becomes equal to or less than a predetermined angle (for example, −90°), the second imaging unit 4 is shielded by the lens hood portion 58, indicating that the second imaging unit 4 is in a non-imaging state.

[0057] A shutter member may be used to shield the lens portion of the imaging unit. Fig. 15 shows the imaging device according to this embodiment having a shutter member 83 in security mode. The shutter member 83 is a shielding unit that is slidably provided relative to the base 53.

[0058] When the imaging device of this embodiment switches from shooting mode to security mode, the first imaging unit 51 rotates outside the range of angles in the tilt direction during shooting, and the support unit 52 rotates outside the range of angles in the pan direction during shooting.

[0059] The imaging device according to this embodiment also has a control unit that realizes its functions using a processor and memory (not shown). The functions of the control unit are realized by a processor such as a CPU executing a program stored in a non-volatile storage medium such as a ROM (Read Only Memory).

[0060] The control unit controls the tilt drive unit or the pan drive unit in response to a user instruction so that at least one of the rotation angle in the pan direction and the rotation angle in the tilt direction is equal to or greater than a predetermined angle. More precisely, the control unit has a function of switching between a shooting mode and a security mode in response to a user instruction. The user instruction is sent to the imaging device via a network, and when the imaging device receives an instruction from the user to switch to the security mode, for example, the control unit controls at least one of the tilt drive unit and the pan drive unit as described above.

[0061] The control unit controls the position of the shutter member 83 based on at least one of the rotation angle in the tilt direction of the first imaging unit 51 and the rotation angle in the pan direction of the support unit 52. The shutter member 83 is controlled to either a first position where it shields the second imaging unit 54, or a second position where it does not shield the second imaging unit 54.

[0062] More specifically, when at least one of the rotation angle in the tilt direction of the first imaging unit 51 and the rotation angle in the tilt direction of the support unit 52 is equal to or greater than a predetermined angle, the control unit controls the shutter member 83 to the first position. On the other hand, when both rotation angles are less than the predetermined angle, the control unit controls the shutter member 83 to the second position. FIG. 15 shows the imaging device in a state in which the shutter member 83 is controlled to the first position. The predetermined angle is the same as that in the first and second embodiments. The rotation angle in each direction can be obtained from the control values ​​of the tilt drive unit and pan drive unit, which are power sources. The control unit obtains the rotation angle in each direction by obtaining the current control values ​​from the tilt drive unit and pan drive unit. Then, the control unit determines whether at least one of the obtained rotation angles in each direction is equal to or greater than a predetermined angle or less than a predetermined angle, and controls the position of the shutter member 83 according to the determination result.

[0063] In this way, the shutter member 83 of the base unit 53 operates in conjunction with at least one of the rotation angle in the tilt direction and the rotation angle in the pan direction. As a result, the shutter member 83 blocks the lens unit 80 of the second imaging unit 54, as shown in FIG.

[0064] With the above configuration, when in security mode, the first imaging unit 51 goes into a non-imaging state, and the second imaging unit 54 is blocked by the shutter member 83, making it possible to clearly indicate that imaging using the imaging device of this embodiment is not possible.

Parts of the above-described embodiments may be combined as appropriate. [Explanation of symbols]
