Description

Technical Field

[0001] The present invention relates to an imaging device.

Background Art

[0002] Conventionally, a camera system is known in which an imaging device is mounted on a pan-tilt device and the imaging device can be pivoted in the pan and tilt directions. Generally, an image sensor provided in an imaging device has a rectangular shape in which the horizontal length of the imaging surface is longer than the vertical length. A state in which the horizontal direction of the imaging surface is made close to the horizontal direction and the vertical direction of the imaging surface is made close to the vertical direction is called a horizontal position, and shooting in the horizontal position is called horizontal shooting. On the other hand, a state in which the vertical direction of the imaging surface is made close to the horizontal direction and the horizontal direction of the imaging surface is made close to the vertical direction is called a vertical position, and shooting in the vertical position is called vertical shooting. In recent years, particularly at the site of video production, the demand for vertical shooting has increased, and in a camera system in which an imaging device is mounted on a pan-tilt device, it is also desired that not only horizontal shooting but also vertical shooting be possible. Further, from the viewpoint of usability, a camera system is desired in which the imaging device mounted on the pan-tilt device can be changed from the horizontal position to the vertical position instead of changing the entire camera system from the horizontal position to the vertical position.

[0003] In a camera system in which the imaging device mounted on the pan-tilt device can be changed from the horizontal position to the vertical position, routing of the cable coming out of the imaging device becomes a problem. In Patent Document 1, a routing method is adopted in which the cable coming out of the imaging device is connected to a nearby imaging device fixing portion and passed through the inside of the imaging device fixing portion to be connected to the tilt axis of the pan-tilt device. By doing so, complicated work related to routing of the cable is made unnecessary.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, Patent Document 1 does not consider the possibility of rotating the imaging device mounted on a pan-tilt device from a horizontal to a vertical position for vertical shooting. Here, we consider the problems that arise when the imaging device is rotated 90 degrees around an axis parallel to the optical axis. If the cable is restricted to exiting from only one side of the imaging device, after rotation the cable will exit from the top or bottom of the imaging device, resulting in an increase in the height of the camera system.

[0006] Therefore, in view of the above problems, the present invention aims to provide an imaging device that can be rotated 90 degrees around an axis parallel to the optical axis without increasing the overall size of the camera system. [Means for solving the problem]

[0007] To solve the above-mentioned problems and achieve the objective, the present invention provides an imaging device that can be fixed in a first position and a second position obtained by rotating the first position by 90 degrees around an axis parallel to the optical axis with respect to a pan-tilt device that can rotate in the pan and tilt directions, wherein the imaging device has an image sensor with a rectangular imaging surface, and the direction parallel to the long side of the imaging surface is defined as the first direction, the direction parallel to the short side of the imaging surface is defined as the second direction, the plane perpendicular to the first direction that passes through the position of the imaging device furthest from the center of the optical axis in the first direction when viewed from the direction parallel to the optical axis is defined as the first plane, and the plane perpendicular to the second direction that passes through the position of the imaging device furthest from the center of the optical axis in the second direction when viewed from the direction parallel to the optical axis is defined as the second plane, wherein when the imaging device is in the first position, the cable connected to the imaging device and the pan-tilt device passes through the first plane, and when the imaging device is in the second position, the cable passes through the second plane. [Effects of the Invention]

[0010] [First Embodiment] Referring to Figure 1, the configuration of the camera system according to the first embodiment of the present invention will be described. In the following description, the directions indicated by the arrows in Figure 1 are defined as the X-axis direction, Y-axis direction, and Z-axis direction, respectively. The X-axis direction corresponds to the left-right direction of the camera system, the Y-axis direction corresponds to the up-down direction of the camera system, and the Z-axis direction corresponds to the direction perpendicular to the X-axis and Y-axis directions. Furthermore, when the camera system is installed on a horizontal surface, the X-axis direction is approximately parallel to the horizontal direction, and the Y-axis direction is approximately parallel to the vertical direction. In addition, rotation around the X-axis direction is defined as rotation in the tilt direction, and rotation around the Y-axis direction is defined as rotation in the pan direction.

[0011] The camera system of this embodiment includes a pan-tilt device 101 and an imaging device 102. As shown in Figure 1, the imaging device 102 for taking pictures is connected to the pan-tilt device 101, and the imaging device 102 is rotated by the operation of the pan-tilt device 101, enabling shooting at various angles of view. In this embodiment, the pan-tilt device 101 includes an imaging device mounting base 103, a head 104, and a base 105, and the pan-tilt device 101 and the imaging device 102 are connected by a cable 106.

[0012] The imaging device 102 can be fixed to the imaging device mounting base 103, and as will be described later, the imaging device 102 can be fixed to the imaging device mounting base 103 in either a horizontal or vertical position. The head 104 is U-shaped and is connected to the imaging device mounting base 103 at a pair of arm regions and to the base 105 at a bottom region connecting the pair of arm regions. Motors (not shown) are provided near the parts of the head 104 connected to the imaging device mounting base 103 and the parts connected to the base 105. By controlling the motors near the part connected to the imaging device mounting base 103, the imaging device 102 can be rotated in the tilt direction, and by controlling the motor near the part connected to the base 105, the imaging device 102 can be rotated in the pan direction. Cable 106 connects the imaging device 102 and the image sensor mounting unit 103 and is used for communicating video signals acquired by the imaging device 102 and control signals to control the imaging device 102.

[0013] Next, a block diagram of the camera system according to this embodiment will be described using Figure 2. The camera system of this embodiment further includes an operating device 201 for operating the pan-tilt device 101 and the imaging device 102. The operating device 201 is an external device separate from the pan-tilt device 101 and the imaging device 102, such as a controller, PC, or portable information terminal. When an operator operates the operating device 201, an instruction signal corresponding to the operation is transmitted from the operating device 201 to the pan-tilt device 101 via the communication unit 208 of the operating device 201 and the communication unit 207 of the pan-tilt device 101. When an operator operates the pan-tilt drive instruction unit 211 of the operating device 201 to give a pan-tilt drive instruction, an instruction signal corresponding to the operation is output from the system control unit 210 to the communication unit 208, and the instruction signal is transmitted to the pan-tilt device 101 via the communication unit 208 and the communication unit 207. The pan-tilt device 101 processes the transmitted instruction signal in the system control unit 206, and a drive command is transmitted from the system control unit 206 to at least one of the pan drive unit 202 and the tilt drive unit 203. When an operator operates the lens drive instruction unit 212 of the operating device 201 to give a lens drive instruction, an instruction signal corresponding to the operation is output from the system control unit 210 to the communication unit 208, and the instruction signal is transmitted to the pan-tilt device 101 via the communication unit 208 and the communication unit 207. The pan-tilt device 101 processes the transmitted instruction signal in the system control unit 206, and a drive command is transmitted from the system control unit 206 to the lens control unit 204 of the imaging device 102 via cable 106. The video signal acquired by the imaging unit 205 having an image sensor of the imaging device 102 is transmitted to the operating device 201 via cable 106, the communication unit 207 and the communication unit 208, and the video corresponding to the video signal is displayed on the video display unit 209 of the operating device 201. Furthermore, the video signal acquired by the imaging unit 205 can also be distributed externally via the communication unit 207. The method by which the pan-tilt drive instruction unit 211 and lens drive instruction unit 212 of the operating device 201 receive operator input may be a known method using levers, dials, switches, buttons, touch panels, etc., provided on the operating device 201.Also, in the above description, an example in which the pan-tilt device 101 has the system control unit 206 and the communication unit 207 has been described. However, the imaging device 102 may have the system control unit 206 and the communication unit 207. In that case, an instruction for pan-tilt driving from the imaging device 102 to the pan-tilt device 101 may be transmitted via the cable 106.

[0014] Next, considering the problems that occur when the imaging device 102 is rotated 90 degrees around an axis parallel to the optical axis, there are roughly three problems. The first problem is that when the cable 106 is restricted so that it can only come out from one side of the imaging device 102, as a result of the rotation, the cable 106 comes out from the upper surface of the imaging device 102, increasing the size of the camera system in the height direction. The second problem is that when trying to rotate the imaging device 102, the cable 106 interferes with the imaging device fixing portion 103 and cannot be rotated. The third problem is that when the cable 106 is led out from the imaging device 102 in the back direction, the cable 106 is likely to hit the pedestal 105 when the imaging device 102 is pivoted upward.

[0015] The structure for fixing the imaging device 102 to the imaging device fixing portion 103 will be described using FIG. 3. The imaging device 102 is screwed and fixed from the bottom surface of the imaging device fixing base 103 by inserting the imaging device fixing screw 301 into the fixing screw insertion hole 302. The imaging device 102 is provided with fixing screw insertion holes 302 on the surface facing the imaging device fixing base 103 in the horizontal position state and on the surface facing the imaging device fixing base 103 in the vertical position state, respectively.

[0016] When switching from horizontal shooting to vertical shooting, first remove the imaging device fixing screw 301 from the state shown in FIG. 3, rotate the imaging device 102 90 degrees around an axis parallel to the optical axis, and place it on the imaging device fixing base 103. Then, insert the imaging device fixing screw 301 removed earlier into the fixing screw insertion hole 302 from the bottom surface of the imaging device fixing base 103 to fix the imaging device 102. Here, when viewed from the Z-axis direction, it is preferable that the distance from the optical axis of the imaging device 102 to the fixing screw insertion hole 302 for horizontal shooting is substantially equal to the distance from the optical axis of the imaging device 102 to the fixing screw insertion hole 302 for vertical shooting.

[0017] The concept of cable arrangement according to this embodiment will be described with reference to FIGS. 4 and 5. FIGS. 4 and 5 are schematic cross-sectional views of the imaging device 102 viewed from the Z-axis direction, and the intersection O (origin) of the X-axis and the Y-axis corresponds to the center of the optical axis. In FIGS. 4 and 5, the outer shape of the imaging device 102 is shown as a circle, but the outer shape of the imaging device 102 is not limited to a specific shape such as a circle or a rectangle. As shown in FIGS. 4 and 5, an image sensor 401 is arranged at a position overlapping the optical axis when viewed from the Z-axis direction in the imaging device 102. The image sensor 401 made of CMOS or the like has a rectangular imaging surface. In the horizontal position state shown in FIG. 4, the short side 402 of the image sensor 401 is parallel to the Y-axis, and the long side 405 of the image sensor 401 is parallel to the X-axis.

[0018] Next, we define virtual planes. Here, the virtual planes may coincide with the actual planes. When viewed from a direction parallel to the optical axis, the plane perpendicular to the first direction passing through the position of the imaging device 102 furthest from the optical axis center in a first direction parallel to the long side of the imaging plane is defined as the virtual plane 404. Also, when viewed from a direction parallel to the optical axis, the plane perpendicular to the second direction passing through the position of the imaging device 102 furthest from the optical axis center in a second direction parallel to the short side of the imaging plane is defined as the virtual plane 407. However, the virtual planes do not exceed the size of the entire pan-tilt device 101. After exiting the outer cover of the imaging device 102, the cable 106 follows the following path. As shown in Figure 4, during horizontal shooting, the cable 106 exits from virtual plane 404, and as shown in Figure 5, during vertical shooting, the cable 106 exits from virtual plane 407. By having the cable 106 pass through the above path, the size of the camera system does not increase. The cable 106 ultimately enters an opening in a support portion 409, which is part of the imaging device mounting base 103 and is positioned to overlap with the head 104 in the X-axis direction. The support portion 409 is positioned to face the virtual plane 404 when the imaging device 102 is in the first orientation and to face the virtual plane 407 when the imaging device 102 is in the second orientation. It is also preferable that the support portion 409 is positioned substantially parallel to the optical axis center of the imaging device 102 in the X-axis direction. Alternatively, it is preferable that the support portion 409 is positioned on the rotation axis of tilt rotation.

[0019] Next, using Figures 6 and 7, we will explain a specific cable routing that takes into account the above cable arrangement concept. Figures 6 and 7 show the holding structure of cable 106. As shown in Figure 6, cable 106 exits from a notch provided at one of the corners of the imaging device 102. The corner where this notch is provided is the corner closest to the intersection of virtual plane 404 and virtual plane 407. An imaging device cable restrictor 601 is provided at the corner of the imaging device 102, restricting cable 106 from protruding beyond the imaging device mounting base 103 in the Y-axis and X-axis directions. Furthermore, the imaging device cable restrictor 601 restricts cable 106 to exit from the virtual plane explained in Figures 4 and 5, depending on the imaging state of the imaging device 102. The imaging device cable restricting section 601 is L-shaped and, when viewed from the Z-axis direction, does not protrude in the X-axis and Y-axis directions more than other parts of the imaging device 102. The cable 106 passes through the space enclosed by the L-shape, making it possible to restrict the cable 106.

[0020] The imaging device cable restrictor 601 may be integrated with the imaging device 102 or it may be removable by screws or the like. The imaging device mounting base 103 is also fitted with a support cable restrictor 602, which restricts the cable 106 from protruding from the imaging device mounting base 103 in the X-axis direction. Rotating the imaging device 102 90 degrees around an axis parallel to the optical axis from the horizontal imaging state in Figure 6 results in the vertical imaging state shown in Figure 7. Since the cable 106 exits from the corner of the imaging device 102, the required length of the cable 106 does not change significantly between the horizontal and vertical imaging states. The support cable restrictor 602 can be slid in the Y-axis direction. For example, the support cable restrictor 602 may be rectangular or U-shaped and be screwed to the support part 409 of the imaging device mounting base 103, so that the support cable restrictor 602 is positioned closer to the imaging device mounting base 103 in the vertical imaging state than in the horizontal imaging state to restrict the cable 106. Furthermore, the imaging device mounting base 103 may be provided with screw holes for vertical shooting and screw holes for horizontal shooting.

[0021] [Second Embodiment] Next, the configuration of the camera system according to the second embodiment of the present invention will be described. In this embodiment, the structure of the imaging device 102 related to holding the cable 106 differs from that of the first embodiment, but the other configurations are the same as those of the first embodiment, so the description of the common parts will be omitted.

[0022] Figures 8 and 9 show the cable holding structure for the cable 106 in this embodiment. In this embodiment, the cable 106 originates from the optical axis center (origin) of the imaging device 102. A cable path groove 802 is provided on the back of the imaging device 102 to allow the cable 106 to pass through. In other words, a notch is provided in the area on the back side that includes the corner closest to the intersection of the virtual plane 404 and the virtual plane 407. In addition, an imaging device cable restrictor 801 is attached to the back of the imaging device 102 to restrict the cable 106 from protruding from the imaging device mounting base 103 in the X-axis and Y-axis directions. The height of the cable path groove 802 is higher than the height of the imaging device cable restrictor 801. When viewed from the Z-axis direction, the optical axis center of the imaging device 102 and the cable path groove 802 overlap. The imaging device cable restrictor 801 restricts the cable 106 according to the concept shown in Figures 4 and 5, depending on the imaging state of the imaging device 102. The imaging device cable restrictor 801 is also removable from the imaging device 102 by screws or the like. The imaging device 102 is provided with screw holes for fixing the imaging device cable restrictor 801, and it is possible to fix the imaging device cable restrictor 801 using the appropriate hole for vertical and horizontal imaging, respectively. In other words, the imaging device 102 has multiple mounting parts for attaching the imaging device cable restrictor 801, and the position of the imaging device cable restrictor 801 can be changed. The cable 106 is restricted by passing through the U-shaped interior of the imaging device cable restrictor 801. The shape of the imaging device cable restrictor 801 may be U-shaped or the like. Otherwise, it is the same as the first embodiment.

[0023] [Third Embodiment] Next, the configuration of the camera system according to the third embodiment of the present invention will be described. In this embodiment, the structure of the imaging device 102 related to holding the cable 106 differs from that of the first and second embodiments, but the other configurations are the same as those of the first embodiment, so the description of the common parts will be omitted.

[0024] Figures 10 and 11 show the cable holding structure for the cable 106 in this embodiment. In this embodiment, the cable 106 emerges from a cable projection groove 1002, which is a groove provided at one of the corners of the imaging device 102. The cable projection groove 1002 is formed by cutting out two adjacent sides of the imaging device 102. In other words, the cutout is provided in the area on the back side that includes the corner closest to the point where the virtual plane 404 and the virtual plane 407 intersect. The cable projection groove 1002 has a cable projection groove side surface 1003 and a cable projection groove bottom surface 1004. The length of the cable projection groove side surface 1003 and the cable projection groove bottom surface 1004 in the Z-axis direction is smaller than the length of the imaging device 102 in the Z-axis direction. An imaging device restricting unit 1001 is installed on the side of the imaging device, and the cable 106 is restricted according to the concept shown in Figures 4 and 5. The imaging device restricting section 1001 is provided on two adjacent sides of the imaging device 102, corresponding to the horizontal and vertical shooting states. The imaging device restricting section 1001 is U-shaped and does not protrude in the Y-axis or Z-axis directions of the imaging device 102. The imaging device restricting section 1001 is removable from the imaging device 102 by screws or the like, and screw holes for fixing the imaging device restricting section 1001 are provided on two adjacent sides of the imaging device 102. The cable 106 is restricted as it passes through the U-shaped interior of the imaging device restricting section 1001. The shape of the imaging device cable restricting section 1001 may be U-shaped or the like. Otherwise, it is the same as in the first embodiment.

[0025] As described above, by holding the cable connected to the imaging device, it becomes possible to rotate the imaging device 90 degrees around an axis parallel to the optical axis without increasing the overall size of the camera system.

[0026] Furthermore, the cable 106 connected to the imaging device 102 may be detachable from an interface such as a connector that is exposed to the outside of the imaging device 102. Similarly, the cable 106 connected to the imaging device mounting base 103 may be detachable from an interface such as a connector that is exposed to the outside of the imaging device mounting base 103.

[0027] Alternatively, the imaging device 102 may be integrally held on the imaging device mounting base 103 so that it can be rotated 90 degrees around an axis parallel to the optical axis.

[0028] Furthermore, although a camera system has been described in which the imaging device 102 can be rotated in both the pan and tilt directions by a pan-tilt device 101, a camera system that can only rotate in either the pan or tilt direction may also be described.

[0029] Furthermore, the imaging device 102 may be of the interchangeable lens type or the integrated lens type.
