Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the prior art disclosed in the above-mentioned Patent Document 1, since a plurality of illuminations are integrally held with each imaging unit, the illuminations cannot be adjusted by arranging each illumination at an arbitrary position. Since the illumination cannot be adjusted by adjusting the illumination position, for example, when light from another illumination such as an electric lamp hits a part of the imaging direction in a dark place and there is a brightness difference in the video, there is a concern that a too bright part may occur and a good video cannot be captured. Further, in the prior art, there is no additional means for illumination, and since the illumination cannot be added, for example, in a place where one illumination is not sufficient to illuminate, such as a dark place away from the imaging device, there is a concern that it is too dark to capture a good video.

[0006] In view of such circumstances, an object of the present invention is to provide an imaging device capable of arbitrarily adjusting the positions and numbers of a plurality of illuminations.

[0007] In order to achieve the above object, an imaging device according to an aspect of the present invention includes a plurality of imaging units movable along a circumferential direction, and a plurality of illumination units that can be fixed to a plurality of first fixing parts provided along the circumferential direction, and the plurality of illumination units are each detachably configured at an arbitrary position of the first fixing part.

Effects of the Invention

[0008] According to the present invention, it is possible to provide an imaging device capable of arbitrarily adjusting the positions and numbers of a plurality of illuminations.

Mode for Carrying Out the Invention

[0010] Hereinafter, with reference to the accompanying drawings, embodiments for carrying out the present invention will be described in detail. The embodiments described below are examples as means for realizing the present invention and should be appropriately modified or changed according to the configuration of the apparatus to which the present invention is applied and various conditions, and the present invention is not limited to the following embodiments.

[0011] <Embodiment 1> Hereinafter, with reference to FIGS. 1 to 6, the imaging device 100 according to Embodiment 1 will be described. Note that details of the lens barrel such as the lens configuration and the arrangement of the wiring of the imaging unit are well known, and thus the description thereof will be omitted.

[0012] FIG. 1 is a cross-sectional view of the imaging device 100 according to Embodiment 1. FIG. 2 is an exploded perspective view showing the configuration of the imaging device 100 according to Embodiment 1.

[0013] As shown in FIGS. 1 and 2, the imaging device 100 includes a base portion 11, a cover unit 12, a plurality of imaging units 13, a rail 14, a plurality of illumination units (illumination portions) 15, and an illumination fixing portion (first fixing portion) 16. The base portion 11 is formed of metal or resin. The rail 14 is formed in an annular shape.

[0014] The cover unit 12 includes a cover member 121, an illumination light transmitting member 122, and a cover frame 123, and is fixed to the base portion 11 by fixing means such as screws. The cover member 121 is fixed to the illumination light transmitting member 122 by fixing means such as screws or adhesion. The cover member 121 is formed of a transparent material, for example, a transparent resin material.

[0015] The illumination light transmitting member 122 is fixed to the cover frame 123 by fixing means such as screws or adhesion. Note that the material of the illumination light transmitting member 122 is formed of a material having a low transmittance in the visible light wavelength band in the present embodiment, but may be a transparent material. The imaging units 13 are arranged circumferentially around the central axis A at the center of the imaging device 100.

[0016] In this embodiment, four imaging units 13 are arranged in the imaging device 100, but there is no limitation on the number as long as it is plural. The illumination unit 15 is arranged circumferentially around the central axis A independently of the imaging unit 13. In this embodiment, it will be described that four illumination units 15 are arranged, but there is no limitation on the number as long as it is plural.

[0017] Next, the configuration of the imaging unit 13 will be described. FIG. 3 is an external view showing the configuration of the imaging unit 13 according to Embodiment 1. As shown in FIG. 3, the imaging unit 13 includes an imaging unit 131, a shift drive unit (second fixing unit) 132, and a tilt drive unit 133. The imaging unit 131 is composed of a lens unit and a sensor unit (not shown).

[0018] The shift drive unit 132 engages with a rail 14 fixed to the base unit 11 to arrange the imaging unit 13 circumferentially around the central axis A and fixedly supports (supports) it so that it can be moved (driven) electrically in the circumferential direction. That is, the imaging unit 13 is fixedly attached to the shift drive unit 132 so as to be movable in the circumferential direction. Further, the shift drive unit 132 can pan-rotate the imaging unit 13 around the central axis A by engaging with a rail portion formed in an annular shape.

[0019] Hereinafter, the driving of the imaging unit 13 in the circumferential direction around the central axis A is referred to as shift driving. That is, the imaging unit 13 is configured to be capable of panning rotation (rotation in the horizontal direction) around the central axis A.

[0020] The tilt drive unit 133 supports the imaging unit 131 so that it can be moved (driven) electrically around the tilt axis B. That is, the imaging unit 13 is configured to be capable of tilt rotation (rotation in the vertical direction) around the tilt axis B. In this embodiment, the shift drive unit 132 and the tilt drive unit 133 are driven electrically, but they may be configured to be rotatable (movable) manually instead of electrically.

[0021] The lighting unit 15 in this embodiment is detachable from the lighting fixing part 16. Further, it is characterized in that it can be attached to any position of the lighting fixing part 16. The lighting fixing part 16 is fixed (arranged) to the base part 11. Hereinafter, the lighting unit 15 and the lighting fixing part 16 will be described.

[0022] FIG. 4 is an external view showing the configuration of the lighting unit 15 and the lighting fixing part 16 according to Embodiment 1. As shown in FIG. 4, the lighting unit 15 is composed of a lighting 151 and a support frame 152.

[0023] The lighting 151 is provided on the support frame 152, for example, to illuminate the imaging direction of the imaging unit 13 during imaging in a dark place or the like and capture a good image. Specifically, it is fixed to the mounting surface 152c of the support frame 152. In this embodiment, the type of the lighting 151 is an LED, but it may be, for example, a fluorescent lamp or an incandescent bulb. Also, the illumination light may be infrared light or visible light.

[0024] The support frame 152 is formed of resin or metal. On the surface of the fixing surface 152a of the support frame 152 that contacts the lighting fixing part 16, two fixing shafts (fixing shaft parts) 152b are fixed by fixing means such as adhesion. Note that the fixing shaft 152b may be integrally formed with the support frame 152. The fixing shaft 152b detachably fixes the lighting unit 15 to the lighting fixing part 16 through a hole 161 described later.

[0025] In this embodiment, the fixing shaft 152b is composed of an elastic member. Specifically, the fixing shaft 152b is a rubber bush. However, it is not limited to this, and if it can be attached to and detached from the lighting fixing part 16, it may be configured as a fitting claw made of metal or resin. The mounting surface 152c is one surface of the support frame 152 that is continuously formed from the fixing surface 152a. The lighting 151 is fixed to the mounting surface 152c by screws or adhesion. A light shielding surface 152d is provided from the mounting surface 152c. The light shielding surface 152d prevents deterioration of the image quality such as ghosting and flare caused by the reflected light of the lighting 151 entering the imaging unit 131.

[0026] FIG. 5 is an external view showing the configuration of the illumination fixing portion 16 according to Embodiment 1. As shown in FIG. 5, the illumination fixing portion 16 is formed in an annular shape around the central axis A on the outer periphery of the imaging unit 13. In the present embodiment, the illumination fixing portion 16 is made of resin. However, it is not limited to this, and the illumination fixing portion 16 may be made of, for example, metal. Further, although the illumination fixing portion 16 is arranged on the base portion 11 as described above, it may be formed as an integral part with the base portion 11. Further, as shown in FIG. 5, the illumination fixing portion 16 is provided on the outer peripheral side of each imaging unit 13.

[0027] In the present embodiment, a plurality of circular holes 161 are provided in the illumination fixing portion 16 as fixing positions for the illumination unit 15. Note that the holes 161 hidden by the illumination unit 15 in the figure are shown by broken lines. The fixing shaft 152b is configured to be detachable from any of the plurality of holes 161.

[0028] The fixing shaft 152b included in the illumination unit 15 is composed of a flange portion and an insertion shaft portion. As shown in FIG. 4 and the like, the flange portion of the fixing shaft 152b has a small diameter portion and a large diameter portion having a diameter larger than that of the small diameter portion, and the small diameter portion and the large diameter portion are continuously connected on a taper. The small diameter portion, the large diameter portion, and the insertion shaft portion of the flange portion are circular when viewed from a plane orthogonal to the axial direction of the flange portion. The illumination fixing portion 16 engages (fits) with the hole 161 by inserting the fixing shaft 152b into the hole 161. Specifically, by inserting it into the hole 161 in the order of the small diameter portion, the large diameter portion, and the shaft portion, it engages with the hole 161. Thereby, the illumination unit 15 can be detachably fixed to the illumination fixing portion 16.

[0029] The holes 161 are formed at intervals (predetermined intervals) at which two fixing shafts 152b can be engaged with each other over the entire circumference of the lighting fixing portion 16. That is, a plurality of holes 161 are formed at predetermined intervals in the circumferential direction of the lighting fixing portion 16. Incidentally, as the interval between adjacent holes 161, it is preferable to be equal to the interval between the two fixing shafts 152. In the present embodiment, the arrangement interval of the fixing shafts 152b is 12° around the central axis A, and the arrangement interval of the holes 161 is 6° around the central axis A. However, the present invention is not limited to this, and the arrangement interval of the fixing shafts 152b, the number and arrangement interval of the holes 161 can be arbitrarily set.

[0030] Next, with reference to FIG. 6, a method for changing the fixing position of the lighting unit 15 will be described. FIG. 6 is an external view showing a method for changing the fixing position of the lighting unit 15 according to the first embodiment.

[0031] To change the fixing position of the lighting unit 15, first, the user (operator) holds the light-shielding surface 152d of the lighting unit 15 fixed to the lighting fixing portion 16 and pulls it downward to remove the two fixing shafts 152b from the holes 161. Then, the fixing shafts 152b are inserted into the holes 161 at arbitrary positions among the plurality of holes 161 of the lighting fixing portion 16. Specifically, by inserting the two fixing shafts 152b into the two holes 161, the lighting unit 15 can be fixed to the lighting fixing portion 16. By this procedure, the user can easily fix the lighting unit 15 at an arbitrary position of the lighting fixing portion 16 formed in an annular shape.

[0032] As described above, in the first embodiment, the lighting unit 15 is detachable at an arbitrary position independently of the imaging unit 13. After the imaging unit 13 is driven to shift, the lighting direction of the lighting unit 15 can be adjusted in an arbitrary direction. Thereby, for example, when there is a brightness difference in the video, the lighting direction can be adjusted so that overly bright portions do not occur, and a good video can be captured. Also, since there are multiple fixing points due to the plurality of holes 161, the number of lighting units 15 can be increased to an arbitrary number with respect to one imaging unit 13. Thereby, for example, even in a dark area where the light of one lighting 151 is insufficient, a good video can be captured by increasing the number of lighting units 15.

[0033] <Second Embodiment> In the first embodiment, the shapes of the plurality of holes 161 of the lighting fixing portion 16 were circular. In the second embodiment, a configuration in which the holes are not circular holes 161 but arc-shaped holes will be described. FIG. 7 is an external view showing the configuration of the lighting fixing portion 16 according to the second embodiment. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. Also, the description of the same configuration as in the first embodiment (the arrangement position of each member, the fixing method of the lighting unit 15, etc.) is also omitted.

[0034] As shown in FIG. 7, in the second embodiment, arc-shaped holes (loose holes) 162 with which the fixing shaft 152b can be engaged are provided over the entire circumference of the lighting fixing portion 16. The arc-shaped holes 162 are formed in the lighting fixing portion 16 with a predetermined length along the circumference. In the second embodiment, four arc-shaped holes 162 are formed in the lighting fixing portion 16 as shown in FIG. 7, but the number is not limited to four, and any number may be used as long as they are formed over the entire circumference of the lighting fixing portion 16.

[0035] In the second embodiment, since the fixing portion is the arc-shaped holes 162, the lighting unit 15 can be moved along the circumferential direction of the arc-shaped holes. That is, the lighting unit 15 is configured to be able to pan-rotate around the central axis A, that is, to move in the pan direction.

[0036] As described above, in the second embodiment, the circumferential position where the lighting unit 15 is fixed to the lighting fixing portion 16 can be adjusted in finer detail than in the first embodiment. Note that the user (operator) may manually change the fixing position of the lighting unit 15. Further, for example, the lighting unit 15 may be driven by a driving unit (not shown) to move the lighting unit 15 along the circumferential direction of the arc-shaped hole.

[0037] <Embodiment 3> In the first and second embodiments, the lighting unit 15 is fixed to the lighting fixing portion 16 by two fixing shafts 152b, and to change the lighting direction, the lighting unit 15 is removed once and inserted again into an arbitrary hole 161 to adjust the lighting direction. In the third embodiment, the lighting unit 15 can be adjusted in lighting direction by rotating (moving) it in the pan direction with the fixing shaft 152b engaged with the hole 161. Note that the same components as those in the first embodiment in the third embodiment are denoted by the same reference numerals, and the description thereof is omitted. Also, the description of the same configuration as that in the first embodiment (the arrangement positions of the respective members, the fixing method of the lighting unit 15, etc.) is omitted.

[0038] FIG. 8 is an external view showing the configuration of the lighting unit 15 according to the third embodiment. FIG. 9 is an external view showing a state in which the lighting unit 15 according to the third embodiment is being panned. As shown in FIG. 8, in the present embodiment, one fixing shaft 152b is provided on the fixing surface 152a of the support frame 152.

[0039] As shown in FIG. 9(A), the fixing shaft 152b engages with the hole 161, whereby the lighting unit 15 is fixed to the lighting fixing portion 16. At this time, since the fixing shaft 152b is engaged with the hole 161, it is prevented from coming out of the hole 161. However, since there is only one fixing shaft 152b, the lighting unit 15 can move in the pan direction with the fixing shaft 152b as the rotation axis, that is, it can rotate in the pan direction.

[0040] As described above, in the third embodiment, the lighting direction of the illumination 151 can be adjusted by rotating the lighting unit 15 in the pan direction with the fixed shaft 154b engaged with the hole 161 without removing the lighting unit 15 once and reinstalling it at a new position.

[0041] <Embodiment 4> In Embodiment 4, another example of a configuration that enables the illumination 151 to move in the pan direction will be described. FIG. 10 is an external view showing the configuration of the lighting unit 15 according to Embodiment 4. FIG. 11 is an external view showing the flow of pan rotation of the lighting unit 15 according to Embodiment 4. In addition, in Embodiment 4, the same components as those in Embodiment 1 are denoted by the same reference numerals, and the description thereof is omitted. Also, the description of the same configuration as that in Embodiment 1 (such as the arrangement position of each member, the fixing method of the lighting unit 15, etc.) is omitted.

[0042] As shown in FIG. 10, a pan rotation shaft 153 is provided on the fixing surface 152a of the support frame (main body) 152 in Embodiment 4. And the pan rotation support portion 154 is connected to the support frame 152 via the pan rotation shaft 153. In addition, two fixing shafts 154a similar to those in Embodiment 1 are provided on the pan rotation support portion 154. In this way, the lighting unit 15 of Embodiment 4 is configured such that the support frame (main body) 152 and the pan rotation support portion 154 provided with the fixing shaft 154a are connected via the pan rotation shaft 153.

[0043] In Embodiment 4, as shown in Fig. 11(A), by engaging the two fixed shafts 154a with the holes 161, the lighting unit 15 can be fixed to the lighting fixing portion 16 in the same manner as in Embodiment 1. Here, in Embodiment 4, as shown in Fig. 11(B), with the lighting unit 15 fixed to the lighting fixing portion 16, the support frame 152 of the lighting unit 15 can rotate in the pan direction (rotate around the axis of the pan rotation shaft 153) with the pan rotation shaft 153 as the rotation axis. That is, when the lighting unit 15 rotates in the pan direction with the pan rotation shaft 153 as the rotation axis, the two fixed shafts 154a and the pan rotation support portion 154 do not rotate in the pan direction, and only the support frame 152 rotates around the pan rotation shaft 153 in the pan direction. Thereby, even in a state where the two fixed shafts 154a are engaged with the holes 161 to fix the lighting unit 15 to the lighting fixing portion 16, the support frame 152 on which the lighting 151 is disposed can be rotated in the pan direction.

[0044] As described above, in Embodiment 4, the lighting direction of the lighting 151 can be adjusted by rotating only the support frame 152 in the pan direction with the pan rotation shaft 153 as the rotation axis.

[0045] <Embodiment 5> In Embodiments 1 to 4, the fixing position of the lighting unit 15 and the method of adjusting the lighting direction have been described. However, when the lighting 151 is infrared light, it is not visible to the naked eye, so it is assumed that it may be difficult to adjust the lighting direction with respect to the imaging angle of view. Therefore, in Embodiment 5, a configuration in which display means for assisting the adjustment of the lighting direction is provided in the lighting unit 15 and the imaging unit 13 will be described. In addition, in Embodiment 5, the same components as those in Embodiment 1 are denoted by the same reference numerals, and their descriptions are omitted. Also, descriptions of the same configurations as in Embodiment 1 (such as the arrangement positions of the respective members and the fixing method of the lighting unit 15) are also omitted.

[0046] FIG. 12 is an external view of the imaging unit 13 and the illumination unit 15 according to Embodiment 5. FIG. 13 is an external view showing the relationship between the imaging angle of view and the illumination angle when the imaging unit 13 and the illumination unit 15 according to Embodiment 5 are adjacent to each other. FIG. 14 is an external view showing the relationship between the imaging angle of view and the illumination angle after adjusting the illumination direction when the imaging unit 13 and the illumination unit 15 according to Embodiment 5 are adjacent to each other.

[0047] In Embodiment 5, as shown in FIG. 12, an imaging angle-of-view display unit 134 as imaging angle-of-view display means is provided on the imaging unit 13. Specifically, the imaging angle-of-view display unit 134 is provided on the shift drive unit 132. The imaging angle-of-view display unit 134 is arranged in a V shape having substantially the same angle as the imaging angle of view 131a of the imaging unit 131 in order to inform the user of the imaging angle of view 131a of the imaging unit 131. That is, by checking the imaging angle-of-view display unit 134, the user can visually recognize (visually confirm) the imaging angle of view of the target imaging unit 131.

[0048] Furthermore, an illumination angle display unit 155 as illumination angle display means is provided on the illumination unit 15. The illumination angle display unit 155 is arranged in a V shape having substantially the same angle as the illumination angle 151a of the illumination 151 in order to inform the user of the illumination angle 151a of the illumination 151. That is, by checking the illumination angle display unit 155, the user can visually recognize (visually confirm) the illumination angle of the target illumination unit 15.

[0049] The imaging angle-of-view display unit 134 and the illumination angle display unit 155 are formed, for example, in a convex shape or a concave shape. Alternatively, the imaging angle-of-view display unit 134 and the illumination angle display unit 155 may be provided on the shift drive unit 132 and the illumination unit 15 by methods such as printing, engraving, and sticking a label. For example, the imaging angle-of-view display unit 134 may be convex and the illumination angle display unit 155 may be concave, and they may be combined in various ways. Hereinafter, a method for adjusting the illumination direction using the illumination angle display unit 155 and the imaging angle-of-view display unit 134 will be described.

[0050] As shown in FIG. 13, there are cases where two imaging units 13 are adjacent due to shift driving. At this time, the ends of the respective imaging angles of view 131a are joined together. This is to enable stitching together the images of each imaging unit 131 to capture a panoramic image. Also, the illumination angle 151a is set larger than the imaging angle of view 131a. This is to illuminate the entire imaging angle of view 131a to capture a good image. However, since the illumination angle 151a is larger than the imaging angle of view 131a, and when two imaging units 13 are adjacent, an illumination overlapping range 151b where two illumination lights overlap occurs around the ends of the adjacent imaging angles of view 131a. Since this illumination overlapping range 151b is brighter than the range illuminated by one illumination light, there is concern that the image will become overexposed.

[0051] In Embodiment 5, in order to avoid such a state, the illumination direction can be adjusted using the illumination angle display unit 155 and the imaging angle of view display unit 134. In adjusting the illumination direction in Embodiment 5, as shown in FIG. 14, each of the two illumination units 15 is rotated (moved) in the pan direction so that the illumination angle display unit 155 on the illumination overlapping range 151b side is aligned on the extension line of the imaging angle of view display unit 134. Thereby, the ends of the adjacent illumination angles 151a are joined together, and the occurrence of the illumination overlapping range 151b can be avoided. Thereby, overexposure of the image can be prevented and a good image can be captured.

[0052] Note that the arrangement of the imaging unit 13 in Embodiment 5 is an example, and also in other arrangements of the imaging unit 13, the illumination angle display unit 155 and the imaging angle of view display unit 134 are effective when adjusting the illumination direction.

[0053] <Embodiment 6> FIG. 15 is an external view showing the configuration of the lighting unit 15 according to Embodiment 6. FIG. 16 is an external view showing the flow of tilt rotation of the lighting unit 15 according to Embodiment 6. The illumination 151 of the lighting unit 15 in Embodiment 6 is configured to be movable in the tilt direction. In addition, in Embodiment 6, the same components as those in Embodiment 1 are denoted by the same reference numerals, and the description thereof is omitted. Also, the description of the same configuration as that in Embodiment 1 (such as the arrangement position of each member, the fixing method of the lighting unit 15, etc.) is omitted.

[0054] In Embodiment 6, in addition to the configuration of Embodiment 1, the lighting unit 15 has a hinge 152f. Specifically, as shown in FIG. 15, a hinge 152f is provided between the fixed surface 152a and the mounting surface 152c of the support frame 152. And the mounting surface 152c to which the illumination 151 is attached is rotatable (movable) in the tilt direction with the hinge 152f as the rotation axis. In addition, in the state where the fixed shaft 152b is engaged with the hole 161, the fixed surface 152a side does not rotate in the tilt direction. That is, the mounting surface 152c and the light shielding surface 152d, which are part of the lighting unit 15 and on which the illumination 151 is arranged, rotate in the tilt direction with the hinge 152f as the rotation axis.

[0055] As described above, in Embodiment 6, by being rotatable in the tilt direction with the hinge 152f as the rotation axis, the illumination direction of the illumination 151 can be adjusted.

[0056] <Embodiment 7> FIG. 17 is an external view showing the configuration of the lighting unit 15 according to Embodiment 7 and the flow of movement in the left - right direction. In Embodiment 7, the illumination 151 in the lighting unit 15 is configured to be movable in the left - right direction. In addition, in Embodiment 7, the same components as those in Embodiment 1 are denoted by the same reference numerals, and the description thereof is omitted. Also, the description of the same configuration as that in Embodiment 1 (such as the arrangement position of each member, the fixing method of the lighting unit 15, etc.) is omitted.

[0057] In Embodiment 6, in addition to the configuration of Embodiment 1, the lighting unit 15 has a slide hole 152g, a slide shaft 156b, and a slide support portion 156.
