Description

[Technical field]

[0001] The present invention relates to an imaging unit support device and an imaging device system. [Background technology]

[0002] In recent years, in studio shooting in video production, for example, pan-tilt camera devices are used as imaging device systems equipped with multiple video camera devices and imaging devices. Many video camera devices and pan-tilt camera devices are equipped with a tally indicator (also called a tally lamp) that lights up according to a signal (tally signal) from a switcher. The performers, camera operators, and camera assistants check the operating status of each device by visually checking the lighting status of this tally indicator. The tally indicator needs to be placed in a position where it can be seen from multiple directions around the device in order to inform various people involved in the shooting of the operating status.

[0003] Patent Document 1 describes a configuration that improves the visible range of a tally display device disposed on the rear of a video camera body. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6660261 Summary of the Invention [Problem to be solved by the invention]

[0005] However, when the configuration of Patent Document 1 is applied to a device that rotates in the pan and tilt directions, such as a pan-tilt camera device, the tally display will be in the blind spot of either the performer, camera operator, or camera assistant.

[0006] The present invention aims to improve visibility from the radially outward direction centered on the pan axis. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the imaging unit support device of the present invention comprises a pan member that supports an imaging unit, a support member that supports the pan member so that it can rotate around a pan axis, and a pair of tally display units arranged on the pan member at diagonal positions across the pan axis, and each of the pair of tally display units is characterized in that it comprises a single arc-shaped light-emitting unit centered on the pan axis, or a light-emitting unit divided into multiple parts along a circumferential direction centered on the pan axis. Effect of the Invention

[0008] According to the present invention, it is possible to improve visibility from the radially outer side centered on the pan axis. [Brief description of the drawings]

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0011] (First embodiment) 1(a) and (b) are perspective views of an imaging device system to which an imaging unit support device according to a first embodiment of the present invention is applied, the imaging device system being a pan-tilt camera device 100 as an example.

[0012] The pan-tilt camera device 100 is mainly composed of a lens unit 101, a camera unit 102, a tilt rotation member 103, a pan rotation member 104, and a base member 106. The lens unit 101 is attached to the camera unit 102 in an exchangeable manner. The lens unit 101 and the camera unit 102 constitute an "imaging unit." The pan rotation member 104 is a pan member that supports the imaging unit via the tilt rotation member 103. The base member 106 is a support member that supports the pan rotation member 104 rotatably around a pan rotation axis 107 (pan axis). The imaging unit support device of this embodiment includes the base member 106, the pan rotation member 104, and the tilt rotation member 103.

[0013] The lens unit 101 is configured in a substantially cylindrical shape centered on an optical axis 109. The camera unit 102 is held by a tilt rotation member 103 together with the lens unit 101. The tilt rotation member 103 is supported by the pan rotation member 104 at both ends. Therefore, the tilt rotation member 103 is supported so as to be rotatable in a tilt direction centered on a tilt rotation axis 105 (tilt axis) relative to the pan rotation member 104. The pan rotation member 104 incorporates a tilt drive unit (not shown). When this tilt drive unit operates, the tilt rotation member 103 rotates together with the imaging unit in the tilt direction relative to the pan rotation member 104. Therefore, the imaging unit is supported by the pan rotation member 104 so as to be tilt rotatable via the tilt rotation member 103.

[0014] The pan rotation member 104 is supported so as to be rotatable in the pan direction around a pan rotation shaft 107 relative to the base member 106. The base member 106 incorporates a pan drive unit (not shown). When this pan drive unit (not shown) operates, the pan rotation member 104 rotates in the pan direction relative to the base member 106. A screw hole (not shown) for mounting a tripod is provided on the bottom surface of the base member 106 (the surface opposite to the side on which the pan rotation member 104 is arranged in the axial direction of the pan rotation shaft 107). The camera unit 102 is detachably held by the tilt rotation member 103. A known drive mechanism may be used as a drive mechanism for rotating the lens unit 101 and the camera unit 102 in the pan direction and tilt direction relative to the base member 106, and therefore a detailed description thereof will be omitted.

[0015] Hereinafter, directions will be referred to based on the pedestal member 106. The thickness direction of the pedestal member 106 is defined as the Y direction. The Y direction is parallel to the axial direction of the pan rotation shaft 107. In particular, the side of the pedestal member 106 on which the pan rotation member 104 is arranged (the upper side in FIG. 1(a)) is defined as the +Y side. The directions perpendicular to the Y direction are defined as the X direction and the Z direction. In the Z direction, the side on which the convex curved surface of the pedestal member 106 is located is defined as the +Z side. In the X direction, the right side when the pedestal member 106 placed on a floor surface or the like is viewed from the +Z side is defined as the +X side.

[0016] The pan rotation member 104 has a first wall portion 104a and a second wall portion 104b extending in the +Y direction. The first wall portion 104a and the second wall portion 104b are disposed symmetrically and diagonally across the pan rotation shaft 107 in the axial direction of the tilt rotation shaft 105.

[0017] A pair of tally display units 108a, 108b are disposed on the pan rotation member 104. The tally display unit 108a is disposed on the outer periphery of the first wall portion 104a, and the tally display unit 108b is disposed on the outer periphery of the second wall portion 104b. The tally display units 108a, 108b are made of a milky white material to transmit and diffuse light from a light-emitting member (not shown) such as an LED provided inside the pan rotation member 104. The tally display units 108a, 108b may have a self-illuminating function.

[0018] 2 and 3 are views of the pan-tilt camera device 100 as viewed from the +Z side and the +Y side, respectively.

[0019] The arrangement of the tally display units 108a and 108b provided in the pan-tilt camera device 100 will be described in detail with reference to FIGS.

[0020] The pair of tally display units 108a, 108b are disposed at diagonal positions across the pan rotation axis 107. More specifically, the pair of tally display units 108a, 108b are disposed rotationally symmetrical with respect to each other with respect to the pan rotation axis 107. When viewed from the Y direction, the pair of tally display units 108a, 108b are also point symmetrical with respect to each other with respect to the pan rotation axis 107. Therefore, the pair of tally display units 108a, 108b are visually recognized equally on the left and right sides when viewed from the optical axis direction.

[0021] 3, the tally display units 108a and 108b are arc-shaped light-emitting units when viewed from the +Y side. The light-emitting surfaces (light-emitting surfaces) of the tally display units 108a and 108b face radially outward from the pan rotation axis 107.

[0022] The virtual line 301 is indicated by a two-dot chain line. The virtual line 301 indicates an area defined by offsetting the rotation trajectory of the outermost circumference of the pan rotation member 104 when the pan rotation member 104 is pan rotated radially outward until it comes into contact with the outermost circumference of the base member 106. In other words, the virtual line 301 corresponds to a virtual circle that passes through the outermost position of the imaging unit support device and is centered on the pan rotation axis 107, and corresponds to the outermost diameter of the imaging unit support device related to the pan operation.

[0023] When viewed from the Y direction, the tally display units 108a, 108b are located between the pan rotation axis 107 and the virtual line 301 in the radial direction centered on the pan rotation axis 107. In other words, the outermost peripheries of the tally display units 108a, 108b centered on the pan rotation axis 107 are located within the range of the virtual line 301. This prevents the imaging unit support device from expanding in the radial direction centered on the pan rotation axis 107.

[0024] Furthermore, in the radial direction centered on the pan rotation shaft 107, the light-emitting surfaces of the tally display units 108a, 108b protrude slightly radially outward from the outer surface of the pan rotation member 104. In other words, the outermost peripheries of the tally display units 108a, 108b centered on the pan rotation shaft 107 are positioned radially outward from the outer surface of the pan rotation member 104. This improves visibility from each direction.

[0025] The light emitting surfaces of the tally display units 108a, 108b may be flush with the outer surface of the pan rotation member 104 or may be recessed from the outer surface of the pan rotation member 104. The tally display units 108a, 108b may be disposed so as to be flush with the virtual line 301 or within the range of the virtual line 301.

[0026] 2, the ends on the +Y side of the first wall portion 104a and the second wall portion 104b are referred to as ends 104a1 and 104b1. In the Y direction, the tally display units 108a and 108b are disposed at a predetermined distance H on the -Y side from the ends 104a1 and 104b1, respectively. It is desirable to minimize the predetermined distance H within a range in which structures required for, for example, ribs for ensuring the strength of the pan rotation member 104 and fixing the tally display units 108a and 108b to the pan rotation member 104 can be disposed.

[0027] In this way, by arranging the tally display units 108a, 108b near the ends 104a1, 104b1 in the axial direction of the pan rotation axis 107, visibility is improved from a viewpoint 201 (Figure 2) that is on the -Y side of the base member 106.

[0028] The visible range of the tally display units 108a and 108b arranged in this manner will now be described.

[0029] Figures 4(a) and (b) are views of the pan-tilt camera device 100 viewed from the +Z side and the -Z side in a state where the pan rotation member 104 has been rotated 40° clockwise as viewed from the +Y side with reference to the pan rotation position shown in Figure 2. Figure 5 is a perspective view of the pan-tilt camera device 100 in the rotation position shown in Figure 2 viewed from the -Y side and the +X side.

[0030] First, the visible range of the tally display units 108a, 108b from the outside in the radial direction (hereinafter simply referred to as the radial direction) centered on the pan rotation axis 107 will be described. As described above, the light emission surfaces of the tally display units 108a, 108b are arc-shaped curved surfaces that are convex radially outward. Therefore, when a user views the pan-tilt camera device 100 from the outside in the radial direction, the user can see a part or the whole of at least one of the tally display units 108a, 108b.

[0031] For example, in Fig. 2, the tally display units 108a and 108b are visible on both sides of the pan rotation axis 107. In Fig. 4(a), the tally display unit 108b is not visible, but the tally display unit 108a is visible. In Fig. 4(b), the tally display unit 108a is not visible, but the tally display unit 108b is visible. In this way, at least one of the tally display units 108a and 108b is visible from the radially outer side at any rotation angle.

[0032] 2, a case will be described in which the pan-tilt camera device 100 is installed at a high place such as on a tripod, and the user looks up at the tally display units 108a, 108b from a viewpoint 201 (high-place installation state). The viewpoint 201 is located on the -Y side of the base member 106, at an angle θ with respect to the pan rotation axis 107. Strictly speaking, the angle θ is the angle formed by a straight line passing through the viewpoint 201 and the intersection point between the pan rotation axis 107 and the optical axis 109, with respect to the pan rotation axis 107, on the -Y side.

[0033] For example, when the pan-tilt camera device 100 is viewed from the viewpoint 201 at an angle θ, the pan-tilt camera device 100 is visually recognized as shown in FIG. 5. Note that FIG. 5 shows the pan-tilt camera device 100 viewed when the angle θ is 5°. The tally display unit 108a is in a position where it can be viewed. When the viewpoint 201 is on the -X side opposite to the position shown in FIG. 2, the tally display unit 108b can be viewed. Therefore, at least one of the tally display units 108a and 108b can be viewed when viewed from any direction around the pan rotation axis 107 on the -Y side of the base member 106.

[0034] In this way, the tally display units 108a and 108b are positioned as high as possible on the pan rotation member 104, so that they are visible even when the pan-tilt camera device 100 is installed in a position where the viewer looks up at it, such as when the pan-tilt camera device 100 is installed at a high place.

[0035] Next, the visibility of the tally display units 108a and 108b when the bottom side of the base member 106 of the pan-tilt camera device 100 is installed on a ceiling or a crane (suspended installation state) will be considered with reference to FIGS.

[0036] 6(a), (b), 7(a), and (b) are perspective views of the pan-tilt camera device 100 in a suspended state, as viewed obliquely from the +Y side (diagonally downward in Figs. 6 and 7). Fig. 8 is a view of the pan-tilt camera device 100 in a suspended state, as viewed from the +Y side (directly below). In addition, in a suspended state, for the convenience of defining the Y direction, the +Y side is the lower side and the -Y side is the upper side.

[0037] 6(a), (b), 7(a), (b), and 8, the pan-tilt camera device 100 is installed in a state rotated 180° around the tilt rotation axis 105 and 180° around the pan rotation axis 107 with reference to the pan rotation position shown in Fig. 1. A user mainly looks up from below at the pan-tilt camera device 100 installed in such a suspended state.

[0038] 6(a), (b), 7(a), and (b) show the appearances seen when the viewpoints are on the -X and +Z sides, +X and +Z sides, +X and -Z sides, and -X and -Z sides, respectively. Either of the tally display units 108a and 108b can be seen from any of the viewpoints. Also, as shown in FIG. 8, even when the pan-tilt camera device 100 is viewed from directly below, the tally display units 108a and 108b protruding from the pan rotation member 104 can be seen. In this way, from any position on the +Y side of the pan-tilt camera device 100, at least one of the tally display units 108a and 108b can be seen in part or in whole.

[0039] According to this embodiment, a pair of tally display units 108a, 108b arranged at diagonal positions across pan rotation axis 107 are made up of a single arc-shaped light emitting unit centered on pan rotation axis 107. This can improve the visibility of tally display units 108a, 108b from the radially outer side centered on pan rotation axis 107.

[0040] Furthermore, since the tally display sections 108a and 108b are disposed near the ends 104a1 and 104b1, the visibility from the diagonal -Y side of the base member 106 can also be improved.

[0041] In addition, since the light-emitting surfaces of the tally display units 108a, 108b protrude further than the outer surface of the pan rotation member 104, visibility from the radial outside around the pan rotation axis 107, as well as visibility from the diagonal -Y side and diagonal +Y side of the pan-tilt camera device 100, can be improved.

[0042] Furthermore, since the outermost portions of the tally display units 108a and 108b centered on the pan rotation axis 107 are located within the range of the imaginary line 301, it is possible to suppress expansion of the imaging unit support device in the radial direction.

[0043] Second embodiment 9(a) and (b) are perspective views of an imaging device system to which an imaging unit support device according to a second embodiment of the present invention is applied, and correspond to FIG. 1(a) and FIG. 1(b).

[0044] The pan-tilt camera device 600 in this embodiment differs from the pan-tilt camera device 100 in the first embodiment mainly in the configuration of the tally display unit. That is, the pan-tilt camera device 600 has a pan rotation member 605 instead of the pan rotation member 104, and has tally display units 601a and 601b instead of the tally display units 108a and 108b. The other configurations are the same as those in the first embodiment. The pan rotation member 605 has a first wall portion 605a and a second wall portion 605b instead of the first wall portion 104a and the second wall portion 104b.

[0045] The tally display unit 601a includes an outer circumferential light-emitting surface 602a and an end surface light-emitting surface 603a. The tally display unit 601b includes an outer circumferential light-emitting surface 602b and an end surface light-emitting surface 603b. The outer circumferential light-emitting surfaces 602a and 602b are disposed on the outer surface of the pan rotation member 605 and face radially outward around the pan rotation shaft 107, similar to the tally display units 108a and 108b. The end surface light-emitting surfaces 603a and 603b are connected to the outer circumferential light-emitting surfaces 602a and 602b, respectively. The end surface light-emitting surfaces 603a and 603b are disposed on the end surface of the pan rotation member 605 on the +Y side in the axial direction of the pan rotation shaft 107, and face the +Y direction.

[0046] Furthermore, flat portions 604a and 604b are formed at the ends of the first wall portion 605a and the second wall portion 605b on the +Y side. The flat portions 604a and 604b are provided on the same plane as the end surface light emission surfaces 603a and 603b.

[0047] FIG. 10 is a diagram of the pan-tilt camera device 600 as viewed from the +Z side, and corresponds to FIG.

[0048] The visible range of the tally display units 601a and 601b arranged in this manner will be described. Since the pan-tilt camera device 600 has outer peripheral light-emitting surfaces 602a and 602b corresponding to the tally display units 108a and 108b, the same visibility as in the first embodiment can be ensured with respect to visibility from all directions around the pan rotation axis 107.

[0049] 9 and 10, the outer peripheral light emitting surfaces 602a, 602b are formed up to the end position on the +Y side of the pan rotation member 605. This is equivalent to the case where the predetermined distance H in FIG. 2 is set to H=0. Therefore, for example, with regard to the visible range of the tally display units 601a, 601b when installed at a high place, it is possible to ensure visibility equal to or greater than that of the tally display units 108a, 108b.

[0050] Fig. 11 is a perspective view of the pan-tilt camera device 600 in a suspended state as viewed obliquely from the +Y side (diagonally downward), and corresponds to Fig. 6(a). Fig. 12 is a view of the pan-tilt camera device 600 in a suspended state as viewed from the +Y side (directly below), and corresponds to Fig. 8. The tilt rotation and pan rotation states shown in Fig. 11 and Fig. 12 are the same as those in Fig. 6(a) and Fig. 8.

[0051] Let us consider the visible range of the tally display units 601a and 601b when the unit is installed suspended from a ceiling. Since the tally display units 601a and 601b have outer peripheral light emitting surfaces 602a and 602b, the visible range from the radial outside around the pan rotation axis 107 can be secured to be the same as that when the pan-tilt camera device 100 is installed suspended from a ceiling (FIG. 6(a)).

[0052] In addition, since the tally display units 601a and 601b have end light emitting surfaces 603a and 603b, a large light emitting area is ensured when viewed from the +Y side. Therefore, the visibility is higher than that of the pan-tilt camera device 100 (FIG. 1).

[0053] 13 is a perspective view of the pan-tilt camera device 600 during the work of attaching a ceiling-suspended installation member. When the work of attaching the ceiling-suspended installation member (not shown) to the bottom surface of the pan-tilt camera device 600 is performed, the pan-tilt camera device 600 is placed in an upside-down position on a workbench 901. At that time, the pan rotation member 605 is placed so that the flat parts 604a and 604b come into contact with the workbench 901.

[0054] Here, as shown in FIG. 10 and FIG. 13, a tilt rotation position of the imaging unit where the optical axis 109 is parallel to the Z direction and the subject side is on the +Z side is taken as an example of a "specific tilt rotation position". As shown in FIG. 10, when the imaging unit is at a specific tilt rotation position, the flat parts 604a and 604b of the pan rotation member 605 protrude from the imaging unit to the +Y side by a distance L. Therefore, the camera unit 102 does not protrude from the flat parts 604a and 604b of the pan rotation member 605 to the +Y side. Therefore, the pan-tilt camera device 600 can be placed on the workbench 901 without the camera unit 102 coming into contact with the workbench 901. This prevents an excessive load from being applied to the camera unit 102. Therefore, the operator can stably perform the work of attaching other members to the bottom surface of the pan-tilt camera device 600.

[0055] From the viewpoint of preventing the imaging unit from contacting the workbench 901, it is sufficient that at least when the imaging unit is in a specific tilt rotation position, a part of the imaging unit does not protrude further toward the +Y side than the flat portions 604a, 604b. Therefore, it is sufficient that there is a tilt rotation position at which the flat portions 604a, 604b of the pan rotation member 605 protrude further toward the +Y side than the imaging unit, and the specific tilt rotation position is not limited to the example.

[0056] According to this embodiment, the tally display units 601a and 601b include outer circumferential light emitting surfaces 602a and 602b, which can provide the same effect as the first embodiment in terms of improving visibility from the radial outside around the pan rotation axis 107 and from the diagonal Y direction.

[0057] Furthermore, since the tally display units 601a and 601b include end light emitting surfaces 603a and 603b, the visibility can be improved especially from the +Y side.

[0058] In addition, since there is a tilt rotation position where the flat parts 604a, 604b of the pan rotation member 605 protrude by the distance L toward the +Y side from the imaging unit, the inverted posture on the work table 901 is stable, and the workability of attaching other members can be improved. In particular, since the flat parts 604a, 604b are provided on the same plane as the end surface light emitting surfaces 603a, 603b, the inverted posture is further stabilized.

[0059] In the first embodiment, the end portions 104a1 and 104b1 of the first wall portion 104a and the second wall portion 104b may be configured to protrude from the imaging portion in the same manner as the flat portions 604a and 604b. The end portions 104a1 and 104b1 may be flat portions corresponding to the flat portions 604a and 604b.

[0060] In each of the above embodiments, the pair of tally display units 108a, 108b (601a, 601b) each consists of a light emitting unit having a circular arc shape centered on the pan rotation axis 107. However, the present invention is not limited to this, and a modified example shown in Fig. 14 may be adopted. In Fig. 14, a modified example of the tally display unit 108b is shown as a representative example, but the same can be applied to the tally display units 108a, 601a, and 601b.

[0061] The tally display unit 108b of the modified example shown in Fig. 14 is made up of a light emitting section divided into a plurality of sections along the circumferential direction centered on the pan rotation axis 107. The more the number of divided light emitting sections, the more preferable it is, but the number may be two or more.

[0062] In each of the above-described embodiments, the imaging unit is not limited to a lens-exchangeable configuration, and may be an imaging device with an integrated lens.

[0063] In the above-described embodiments, the imaging unit is detachable from the imaging unit support device, but this is not limiting. That is, an integrated imaging unit and imaging unit support device (for example, the pan-tilt camera device 100, 600) may be called the imaging unit support device of the present invention, or may be called the imaging device.

[0064] In each of the above embodiments, accessories other than the imaging unit may be detachably attached to the imaging unit support device of the present invention. In addition, in each of the above embodiments, the tally display unit may fulfill the role of a tally indicator by displaying characters or images rather than emitting light (radiating light). Alternatively, the tally display unit may be provided with a plurality of members of different colors, and the members exposed to the outside from the tally display unit may be interchanged to fulfill the role of a tally indicator.
