  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate. However, more detailed description than necessary may be omitted. For example, detailed descriptions of already well-known matters and repeated descriptions for substantially the same configuration may be omitted. This is to avoid the following description from becoming unnecessarily redundant and to facilitate understanding by those skilled in the art.

  The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

  FIG. 1 is a diagram illustrating a side view of a surveillance camera according to an embodiment of the present disclosure. The surveillance camera shown in FIG. 1 is installed, for example, inside or outside a signal pole or telephone pole installed at an intersection or a building such as a building. The surveillance camera is connected to an information processing apparatus such as a personal computer, for example, and transmits a captured image to the information processing apparatus. In the following, the three coordinate axes shown in FIG. 1 are set for the surveillance camera.

  As shown in FIG. 1, the surveillance camera has a housing 1 and a cover 2. The housing 1 has a fixed surface A1 at the bottom. The surveillance camera is fixed to a building such as a traffic light pole, a telephone pole, or a building, for example, via the fixed surface A1.

  The cover 2 is a dome-shaped cover and has a hemispherical shape. The cover 2 is made of a transparent material such as glass or plastic. A portion indicated by an arrow A <b> 2 in FIG. 1 indicates the zenith of the cover 2.

  The cover 2 is fixed to the housing 1 so as to cover a plurality of cameras (for example, see FIG. 2 or FIG. 3) attached to the housing 1. The cover 2 protects a plurality of cameras attached to the housing 1.

  FIG. 2 is a side view of the surveillance camera with the cover 2 removed. In FIG. 2, the same components as those in FIG.

  As shown in FIG. 2, the surveillance camera has a plurality of cameras 11a, 11b, and 11c. The surveillance camera according to the present embodiment has four cameras, but in FIG. 2, the other camera is hidden behind the camera 11b (−x axis direction).

  FIG. 3 is a front view of the surveillance camera with the cover 2 removed. 3, the same components as those in FIG. 2 have the same reference numerals. As shown in FIG. 3, the surveillance camera has four cameras 11a to 11d. The shooting directions of the cameras 11a to 11d (for example, the direction extending vertically from the lens surface) are adjusted (moved) by the user's hand.

  The housing 1 has a base 12. The base 12 is a plate-like member, and has a circular shape when viewed from the front of the apparatus (+ z-axis direction). Although described in detail below, the cameras 11 a to 11 d are movably fixed (connected) to the base 12.

  The center of the base 12 is located just below the zenith of the cover 2 (just below the zenith). For example, the center of the base 12 is located directly below the zenith of the cover 2 indicated by an arrow A2 in FIG.

  FIG. 4 is a side view of the surveillance camera with the cover 2 removed. 4, the same components as those in FIGS. 2 and 3 are denoted by the same reference numerals. In FIG. 4, the cameras 11a and 11c are shown for the sake of simplicity, and the cameras 11b and 11d are not shown. As shown in FIG. 4, the surveillance camera has connecting members 21aa, 21ab, and 21c.

  The connecting member 21aa extends from the center of the base 12 toward the top of the cover 2. In other words, the connecting member 21aa extends from the base 12 located immediately below the zenith of the cover 2 toward the zenith of the cover 2.

  The connecting member 21aa has an axis extending from the center of the base 12 toward the top of the cover 2 and rotates around this axis. For example, the axis A <b> 11 illustrated in FIG. 4 indicates the axis of the connecting member 21 aa extending from the center of the base 12 toward the top of the cover 2. The connecting member 21aa rotates in the left-right direction about the axis A11 of FIG.

  One end of the connecting member 21ab is connected at the end of the connecting member 21aa opposite to the base 12. Further, the other end of the connecting member 21ab is connected to the camera 11a.

  One end of the connecting member 21ab is connected to the connecting member 21aa so that the other end is movable in the elevation angle direction with respect to the base 12. That is, the other end of the connecting member 21ab is movable in the elevation angle direction with respect to the base 12. Hereinafter, the elevation angle direction with respect to the base 12 may be simply referred to as an elevation angle direction.

  As described above, the camera 11a is connected to the other end of the connecting member 21ab. The other end of the connecting member 21ab is movable in the elevation angle direction. Accordingly, the shooting direction of the camera 11a is movable in the elevation direction. For example, an arrow A <b> 12 illustrated in FIG. 4 indicates an elevation angle direction with respect to the base 12. The shooting direction of the camera 11a is movable in the direction of arrow A12 in FIG.

  The connecting member 21 c extends from the position off the center of the base 12 toward the top of the cover 2. For example, the connecting member 21c extends toward the zenith of the cover 2 from a position deviated from the point where the axis A11 of the connecting member 21aa and the base 12 intersect (the center of the base 12). As will be described below, the connecting member 21c is connected to the base 12 so as to move on a circumference centered on the center of the base 12 (see, for example, the rail 41 in FIG. 10 or FIG. 12).

  The camera 11c is connected to the end of the connecting member 21c opposite to the base 12. The camera 11c is connected to the connecting member 21c so that the photographing direction can move in the elevation angle direction. For example, an arrow A <b> 13 illustrated in FIG. 4 indicates an elevation angle direction with respect to the base 12. The shooting direction of the camera 11c is movable in the direction of arrow A13 in FIG.

  FIG. 5 is a side view of the surveillance camera with the cover 2 removed. In FIG. 5, the same components as those in FIG. 4 are denoted by the same reference numerals. In FIG. 5, the camera 11a is shown for ease of explanation, and the illustration of the camera 11c shown in FIG. 4 is omitted. As shown in FIG. 5, the surveillance camera has a shaft member 31a.

  The shaft member 31a connects the connecting member 21aa and the connecting member 21ab. The shaft member 31a connects the connecting member 21ab to the connecting member 21aa so that the other end (the side on which the camera 11a is attached) of the connecting member 21ab is movable in the elevation angle direction.

  FIG. 6 is a diagram illustrating a state in which the shooting direction of the camera 11 a is directed to the zenith direction of the cover 2. In FIG. 6, the same components as those in FIG.

  The connecting member 21ab rotates with respect to the connecting member 21aa with the central axis of the shaft member 31a as a rotation axis. Thereby, the photographing direction of the camera 11a can face the zenith direction (+ z-axis direction) of the cover 2, as shown in FIG.

  The connecting member 21ab may rotate with respect to the connecting member 21aa so that the other end straddles the zenith direction. That is, the shooting direction of the camera 11a may exceed the zenith direction of the cover 2 and move.

  FIG. 7 is a diagram illustrating a state in which the shooting direction of the camera 11 a is moved beyond the zenith direction of the cover 2. In FIG. 7, the same components as those in FIGS. 5 and 6 are denoted by the same reference numerals.

  The shooting direction of the camera 11a shown in FIG. 7 is movable across the zenith direction of the cover 2 with respect to the camera 11a shown in FIG. For example, an alternate long and short dash line A <b> 21 illustrated in FIG. 7 indicates the zenith direction of the cover 2. The shooting direction of the camera 11a is movable across the alternate long and short dash line A21 as indicated by an arrow A22 in FIG. The movable range of the photographing direction in the elevation direction of the camera 11 a is, for example, 10 to 110 degrees with respect to the base 12.

  Cameras 11 b to 11 d (see, for example, FIG. 3) other than the camera 11 a are not movable with the shooting direction straddling the zenith direction of the cover 2. That is, of the four cameras 11 a to 11 d, one camera 11 a moves across the zenith direction of the cover 2. The movable range in the photographing direction in the elevation direction of the cameras 11b to 11d is, for example, 10 degrees to 80 degrees with respect to the base 12.

  The shaft member 31 a may be provided so as to be positioned at the center point of the hemispherical cover 2. In this case, the camera 11 a (the lens of the camera 11 a) moves so that the locus in the elevation angle direction with respect to the base 12 follows the curved surface of the cover 2. Thereby, the camera 11a can move in the elevation angle direction with a constant distance from the cover 2, and can suppress a change in the refractive index of the cover 2 due to a change in the distance from the cover 2.

  As described with reference to FIG. 4, the connecting member 21aa rotates in the left-right direction with the axis A11 shown in FIG. 4 as the rotation axis. That is, the shooting direction of the camera 11a rotates in the azimuth direction in the base 12 with the axis extending from the base 12 extending in the zenith direction of the cover 2 as a rotation axis.

  FIG. 8 is a diagram for explaining the rotation of the camera 11a with the zenith direction of the cover 2 as the rotation axis. FIG. 8 is a perspective view of the surveillance camera viewed from the cover 2 side. In FIG. 8, the same components as those in FIG.

  As shown in FIG. 8, the connecting member 21aa extends from the center of the circular base 12 toward the zenith direction of the cover 2, and rotates in the left-right direction with the axis A31 of FIG. 8 as the rotation axis. Thereby, the photographing direction of the camera 11a connected to the connecting members 21aa and 21ab rotates in the left-right direction with the axis A31 as the rotation axis.

  FIG. 9 is a diagram illustrating a state in which the camera 11a rotates about the zenith direction of the cover 2 as a rotation axis. 9, the same components as those in FIG. 8 are denoted by the same reference numerals.

  The shooting direction of the camera 11a shown in FIG. 9 changes from the shooting direction of the camera 11a shown in FIG. As shown in FIGS. 8 and 9, the camera 11 a rotates around the connecting member 21 aa extending from the center of the circular base 12 toward the zenith direction of the cover 2 as a rotation axis.

  FIG. 10 is a diagram showing the housing 1 and the base 12 of the surveillance camera. 10, the same components as those in FIG. 9 are denoted by the same reference numerals. As shown in FIG. 10, the base 12 has a circular rail 41 having a certain width. The center of the circular rail 41 coincides with the center of the base 12.

  FIG. 11 is a view in which a connecting member 21aa is attached to the base 12 shown in FIG. In FIG. 11, the same components as those in FIG. 10 are denoted by the same reference numerals.

  As shown in FIG. 11, the connecting member 21aa has a gripping portion 22a. The grip portion 22a extends from the connecting member 21aa along the azimuth direction in parallel with the surface of the base 12.

  The connecting member 21aa rotates in the azimuth direction in the base 12 in accordance with the user's operation of the grip portion 22a. For example, the connecting member 21aa rotates in the direction of the arrow A41 in FIG. Thereby, the imaging direction of the camera 11a connected to the connecting member 21aa via the connecting member 21ab rotates in the azimuth direction (see the camera 11a in FIGS. 8 and 9). Hereinafter, the azimuth angle direction in the base 12 may be simply referred to as an azimuth angle direction.

  As shown in FIG. 11, the connecting member 21 aa that connects the camera 11 a whose shooting direction faces the zenith direction of the cover 2 is connected to the base 12 at the center of the base 12. On the other hand, the connecting member that connects the cameras 11b to 11d whose shooting direction is not directed to the zenith direction of the cover 2 deviates from the center of the base 12 and is connected to the base 12 (rail 41).

  FIG. 12 is a view for explaining the connection of the connecting members 21aa and 21b to 21d to the base 12. 12, the same components as those in FIG. 11 are denoted by the same reference numerals. FIG. 12 is a perspective view of the surveillance camera viewed from the cover 2 side.

  A hole 51 is formed in the center of the rail 41. A concentric hole 52 is formed outside the rail 41.

  The camera 11a is connected to the connecting member 21ab. The connecting member 21ab is connected to the connecting member 21aa via the shaft member 31a. The connecting member 21aa includes a gripping portion 22a, a fitting portion 23a, and a protruding portion 24a (partially hidden behind the camera 11b) extending in the upward direction in the figure.

  The protrusion 24 a is passed through a hole 51 formed in the center of the base 12. The fitting part 23 a has a hollow shape so as to sandwich the rail 41. The fitting portion 23 a is slidably fitted to the rail 41 of the base 12. That is, the fitting portion 23 a slides along the rail 41. Thereby, connection member 21ab can rotate to an azimuth direction according to operation of user's grasping part 22a.

  The camera 11b is connected to the connecting member 21b via a shaft member (not shown). The camera 11b rotates about the central axis of the shaft member as a rotation axis so that the photographing direction can move in the elevation angle direction.

  The connecting member 21b has a grip portion 22b and a fitting portion (not shown). The connecting member 21b slides along the rail 41 according to the user's operation of the grip portion 22b. That is, the shooting direction of the camera 11b can be rotated in the azimuth direction according to the user's operation.

  The camera 11c is connected to the connecting member 21c via the shaft member 31c. The camera 11c rotates about the shaft member 31c as a rotation axis so that the photographing direction can move in the elevation angle direction.

  The connecting member 21c has a gripping part 22c and a fitting part 23c. The fitting portion 23 c has a hollow shape so as to sandwich the rail 41. The fitting portion 23 c is slidably fitted to the rail 41 of the base 12. That is, the fitting portion 23 c slides along the rail 41. Thereby, the connection member 21c slides along the rail 41 according to the user's operation of the grip portion 22c, and the photographing direction of the camera 11c can be rotated in the azimuth direction.

  The camera 11d is connected to the connecting member 21d via the shaft member 31d. The camera 11d rotates about the shaft member 31d as a rotation axis so that the photographing direction can be moved in the elevation angle direction.

  The connecting member 21d has a grip portion 22d and a fitting portion 23d. The fitting portion 23d has a hollow shape so as to sandwich the rail 41. The fitting portion 23d is slidably fitted to the rail 41 of the base 12. That is, the fitting portion 23 d slides along the rail 41. Thereby, the connecting member 21d slides along the rail 41 in response to the user's operation of the grip portion 22d, and the shooting direction of the camera 11d rotates in the azimuth direction.

  The connecting members 21b to 21d of the cameras 11b to 11d have the same shape or structure. The connecting members 21 b to 21 d of the cameras 11 b to 11 d are connected to the base 12, deviating from the center of the base 12. On the other hand, the connecting member 21aa of the camera 11a is connected to the base 12 at the center of the base 12. Thereby, camera 11a can face the zenith direction of cover 2 among a plurality of cameras 11a-11d.

  FIG. 13 is a diagram illustrating the connection of the connecting members 21aa and 21b to 21d to the base 12. In FIG. 13, the same components as those in FIG. FIG. 13 is a perspective view of the surveillance camera viewed from the housing 1 side. FIG. 13 also shows the fitting portion 23b of the connecting member 21b not shown in FIG.

  As shown in FIG. 13, a flange 25a is formed at the end of the fitting portion 23a of the connecting member 21aa. The flange portion 25 a is passed through a concentric hole 52 formed in the base 12 and comes into contact with the back surface of the base 12. The connecting member 21aa does not fall in the direction of the cover 2 because the flange portion 25a is supported on the back surface of the base 12.

  A flange portion 25b is formed at the end of the fitting portion 23b of the connecting member 21b. The flange portion 25 b is passed through a concentric hole 52 formed in the base 12 and comes into contact with the back surface of the base 12. The connecting member 21 b does not fall in the direction of the cover 2 because the flange portion 25 b is supported on the back surface of the base 12.

  A flange portion 25c is formed at the end of the fitting portion 23c of the connecting member 21c. The flange portion 25 c is passed through a concentric hole 52 formed in the base 12 and comes into contact with the back surface of the base 12. The connecting member 21 c does not fall in the direction of the cover 2 because the flange portion 25 c is supported on the back surface of the base 12.

  A flange portion 25d is formed at the end of the fitting portion 23d of the connecting member 21d. The flange portion 25 d is passed through a concentric hole 52 formed in the base 12 and comes into contact with the back surface of the base 12. The connecting member 21d does not fall in the direction of the cover 2 because the flange portion 25d is supported by the back surface of the base 12.

  The flange portion 25a of the connecting member 21aa has a protruding portion 26a. When the protrusion 26a moves to the position of the protrusion 12a provided on the back surface of the base 12 by the rotation of the connecting member 21aa in the azimuth direction, the protrusion 26a contacts the protrusion 12a. As a result, the connecting member 21aa does not rotate 360 degrees or more in the azimuth direction. In addition, when the connecting member 21aa does not rotate 360 degrees or more, the other connecting members 21b to 21d do not rotate 360 degrees or more.

  Wirings of the cameras 11 a to 11 d are guided to the inside of the housing 1 through the holes 51. Since the connecting members 21aa and 21b to 21d do not rotate 360 degrees or more in the azimuth direction, the wires of the cameras 11a to 11d are prevented from being twisted more than necessary. In addition, the protrusion part 26a may have any one of the flange parts 25b to 25d of the connecting members 21b to 21d.

  FIG. 14 is a perspective view seen from the front of the camera 11a. FIG. 14 shows a camera 11a and a connecting member 21ab to which the camera 11a is connected.

  As shown in FIG. 14, the camera 11a has a lens 61 in the front. The camera 11a rotates in the left-right direction with the shooting direction as the rotation axis. For example, as shown by an arrow A51 in FIG. 14, the camera 11a rotates in the left-right direction with the shooting direction indicated by the alternate long and short dash line as the rotation axis.

  The camera 11a rotates with respect to the connecting member 21ab in the left-right direction with the imaging direction as the rotation axis. The connecting member 21ab does not rotate in the left-right direction with the imaging direction as the rotation axis.

  FIG. 15 is a perspective view seen from the rear of the camera 11a. 15, the same components as those in FIG. 14 are denoted by the same reference numerals.

  The camera 11a has a gear tooth-like engagement portion 71 on the back. The engaging part 71 is formed along the circumference.

  The engaging portion 71 rotates as the camera 11a rotates about the shooting direction. For example, when the camera 11a rotates in the direction indicated by the arrow A52 in FIG. 15, the engaging portion 71 also rotates as the camera 11a rotates.

  The connecting member 21ab has a lever 72 (see also FIG. 16). The lever 72 has a claw 72 a that engages with the groove of the engaging portion 71 at its end. The lever 72 urges the claw 72 a in the groove direction of the engaging portion 71.

  The engaging portion 71 formed on the back portion of the camera 11 a rotates with respect to the lever 72. Since the claw 72a of the lever 72 is engaged with the engaging portion 71, the camera 11a is held (maintained) at a predetermined angle rotated by the user.

  The camera 11a rotates in a range in which the engaging portion 71 engages with the claw 72a of the lever 72. For example, when the portion indicated by the arrow A53 of the engaging portion 71 reaches the position of the claw 72a of the lever 72, the camera 11a does not rotate in the direction of the arrow A54.

  FIG. 16 is an exploded perspective view seen from the front of the camera 11a. In FIG. 16, the same components as those in FIGS. 14 and 15 are denoted by the same reference numerals.

  As illustrated in FIG. 16, the connecting member 21ab includes a circular plate portion 81 having a circular shape. The camera 11a includes an engaging member 82, covers 83 and 86, an image sensor 84, and a filter 85. The engaging member 71 is formed with the engaging portion 71 described with reference to FIG.

  The circular plate portion 81 of the connecting member 21ab has a diameter larger than the opening of the engaging member 82. The circular plate portion 81 of the coupling member 21ab is passed through the opening of the engagement member 82, and the engagement member 82 through which the circular plate portion 81 is passed is fixed to the cover 83. Thereby, the cover 83 can rotate with respect to the connection member 21ab.

  The image sensor 84 and the filter 85 are housed in covers 83 and 86. The covers 83 and 86 have a circular shape, and a part thereof protrudes downward in the drawing. The substantially square imaging element 84 is accommodated in a circular portion of the cover 83. The substantially rectangular filter 85 is housed in a circular portion of the cover 83 and a portion protruding downward in the drawing.

  The camera 11a can be reduced in size by forming the covers 83 and 86 as shown in FIG. For example, if the shapes of the covers 83 and 86 are circular, the length in the longitudinal direction of the filter 85 must be the diameter, and the volume of the covers 83 and 86 increases. On the other hand, the covers 83 and 86 shown in FIG. 16 have a circular portion that accommodates the substantially square-shaped imaging element 84 and a protruding portion that accommodates the substantially rectangular filter 85 protruding from the circular portion. However, the size is reduced.

  FIG. 17 is an exploded perspective view seen from the rear of the camera 11a. In FIG. 17, the same components as those in FIG. 16 are denoted by the same reference numerals.

  As described in FIG. 16, the circular plate portion 81 of the connecting member 21ab is passed through the opening of the engaging member 82. The engaging member 82 is fixed to the back portion of the cover 83 in a state where the circular plate portion 81 of the connecting member 21ab is passed through the opening.

  Thereby, the cover 83 rotates with respect to the connection member 21ab, and the engaging member 82 fixed to the back part of the cover 83 also rotates with respect to the connection member 21ab. Then, the engaging portion 71 formed on the engaging member 82 rotates with respect to the claw 72a of the lever 72, and the claw 72a of the lever 72 engages with the groove of the engaging portion 71, whereby the camera 11a is The rotational position is maintained (maintained) at an angle of.

  The cover 83 has stopper portions 83a and 83b. The stopper portions 83a and 83b regulate the rotation of the camera 11a. For example, when the stoppers 83 a and 83 b reach the position of the claw 72 a of the lever 72 by the rotation of the cover 83, the stopper parts 83 a and 83 b come into contact with the claw 72 a of the lever 72. The stopper portions 83a and 83b stop the rotation of the cover 83 by contacting the claw 72a of the lever 72 so that the cover 83 does not further rotate.

  That is, the camera 11 a can rotate in a range where the engaging portion 71 engages with the claw 72 a of the lever 72. In other words, the camera 11a rotates up to a predetermined angle in the left-right direction with the shooting direction as a rotation axis, and cannot rotate beyond the predetermined angle.

  18A, 18B, and 18C are diagrams illustrating the rotation range of the camera 11a. Assume that the surveillance camera is in a state where the zenith portion of the cover 2 (not shown) faces vertically downward. In this state, it is assumed that the camera 11a is in a state where a portion protruding from the circular portion is directed vertically upward as shown in FIG. 18A. At this time, the vertical direction of the landscape or the like taken by the camera 11a matches the vertical direction of the image displayed on the display device.

  As shown in FIG. 18B, the camera 11a can rotate counterclockwise in the drawing to an angle θ. In other words, the maximum rotation angle of the camera 11a in the counterclockwise direction in the drawing is θ.

  As shown in FIG. 18C, the camera 11a can rotate clockwise to an angle θ in the drawing. In other words, the maximum rotation angle of the camera 11a in the clockwise direction in the figure is θ.

  The cameras 11c to 11d also have the same configuration as the camera 11a described with reference to FIGS. 14, 15, 16, 17, 17, 18A, 18B, and 18C. That is, the cameras 11c to 11d can also be rotated up to a predetermined angle in the left-right direction with the shooting direction as a rotation axis, like the camera 11a. However, the members of the cameras 11c to 11d corresponding to the connecting member 21ab of the camera 11a are shorter in length than the connecting member 21ab (for example, see the connecting portion between the camera 11c and the connecting member 21c in FIG. 4).

  Note that the information processing apparatus connected to the monitoring camera may invert the vertical direction of the image captured by the monitoring camera or may invert the horizontal direction, for example, with software.

  Hereinafter, an example in which a surveillance camera is installed at an intersection will be described.

  FIG. 19 is a diagram illustrating an example of an intersection where a surveillance camera is installed. The white part in FIG. 19 shows the road 101. The hatched portion in FIG. 19 indicates the sidewalk 102. A black circle portion in FIG. 19 shows a traffic light pillar 103 on which a surveillance camera is installed. For example, the surveillance camera is installed above the pillar 103 so that the cover 2 faces the ground. Note that a grid-like line A61 for representing the perspective of the image captured by the monitoring camera is superimposed on the road 101.

  FIG. 20 is a diagram illustrating an example of the camera arrangement of the surveillance cameras installed at the intersection. 20, the same components as those in FIG. 3 are denoted by the same reference numerals. In FIG. 20, the shape and the like of the monitoring camera are simplified.

  The cameras 11a to 11d are arranged as shown in FIG. For example, the camera 11 a is arranged so that the shooting direction faces the zenith direction of the cover 2. The cameras 11b and 11d are arranged such that the shooting directions are opposite to each other. The camera 11c is arranged so that the shooting direction is 90 degrees with respect to the shooting directions of the cameras 11b and 11d.

  The surveillance camera is installed on the pillar 103 of the traffic light so that the base 12 faces the ground. Therefore, the camera 11a images the ground directly below.

  The surveillance camera is installed on the pillar of the traffic light so that the shooting direction of the camera 11c is directed in the direction of arrow A62 in FIG. An area between thick solid lines A63a and A63b in FIG. 19 indicates a shooting range of the camera 11c. An area surrounded by a dotted line A64 in FIG. 19 indicates a shooting range of the camera 11a. From the one-dot chain line A65 in FIG. 19, the area on the right side in the drawing indicates the photographing range of the camera 11d. The lower region in the drawing from the one-dot chain line A66 in FIG. 19 indicates the photographing range of the camera 11b.

  FIG. 21 is a diagram showing an example of an image taken with the camera arrangement example of FIG. When the intersection shown in FIG. 19 is photographed with the camera arrangement shown in FIG. 20, for example, images A71 to A74 shown in FIG. 21 are displayed on the display device.

  An image A71 in FIG. 21 is an image taken by the camera 11a in FIG. The camera 11 a is photographing the ground directly below because the photographing direction is directed to the zenith direction of the cover 2.

  The image A72 is an image taken by the camera 11c in FIG. An image A73 is an image taken by the camera 11b of FIG. An image A74 is an image taken by the camera 11d in FIG.

  FIG. 22 is a diagram illustrating another camera arrangement example. In FIG. 22, the same components as those in FIG. 20 are denoted by the same reference numerals. In FIG. 22, the shape and the like of the monitoring camera are simplified.

  In FIG. 22, the cameras 11 a to 11 d are arranged on the base 12 so as to be equally spaced on a semicircular circumference. The cameras 11a and 11d are disposed at both ends of the semicircle.

  For example, a dotted line A81 shown in FIG. 22 indicates a semicircle. The cameras 11a to 11d are arranged at substantially equal intervals on the semicircular circumference indicated by the dotted line A81. The cameras 11a and 11d are disposed at both ends of a semicircular circumference indicated by a dotted line A81.

  When the cameras 11a to 11d are arranged as shown in FIG. 22, panoramic images of 180 degrees using the four cameras 11a to 11d are obtained. When the cameras 11a to 11d are arranged as shown in FIG. 3, a panoramic image of 360 degrees is obtained.

  The surveillance camera is installed on the pillar of the traffic light so that the x-axis direction in FIG. 22 faces the direction of the arrow A62 in FIG.

  FIG. 23 is a diagram showing an example of an image taken with the camera arrangement example of FIG. 22. When the intersection of FIG. 19 is taken with the camera arrangement shown in FIG. 22, the display device shows, for example, FIG. 23. Images A91 to A94 are displayed.

  An image A91 in FIG. 23 is an image taken by the camera 11a in FIG. An image A92 is an image taken by the camera 11b of FIG. An image A93 is an image taken by the camera 11c in FIG. An image A94 is an image taken by the camera 11d in FIG.

  The panoramic image shown in FIG. 23 is not continuous in the horizontal direction. For example, the road extending to the left of the image A92 is not connected to the road of the image A91. Further, the road extending to the right of the image A93 is not connected to the road of the image A94.

  As described above, the cameras 11a to 11d can rotate in the left-right direction with the shooting direction as a rotation axis (see, for example, FIGS. 18A to 18C). By rotating the cameras 11a to 11d arranged in a panorama on the semicircle, panoramic images can be continued in the horizontal direction.

  FIG. 24 is a diagram illustrating an example of a panoramic image in which the horizontal direction is continuous. An image A101 in FIG. 24 is an image taken by the camera 11a in FIG. An image A102 is an image taken by the camera 11b in FIG. An image A103 is an image taken by the camera 11c in FIG. An image A104 is an image taken by the camera 11d in FIG.

  When the cameras 11a to 11d are rotated in the left-right direction with the shooting direction as the rotation axis, panoramic images can be continued in the horizontal direction. For example, when the camera 11a is rotated counterclockwise when viewed from the front, the image A91 illustrated in FIG. 23 rotates as illustrated in an image A101 in FIG. When the camera 11d is rotated clockwise as viewed from the front, the image A94 shown in FIG. 23 is rotated as shown by an image A104 in FIG. The cameras 11b and 11c are also rotated so that the panoramic images are continuous in the horizontal direction.

  The maximum rotation angle of the cameras 11a to 11d is an angle in which the images of the two cameras that capture both ends of the panoramic image are continuous with the images captured by the other cameras in the horizontal direction. For example, the maximum rotation angle of the cameras 11a to 11d is such that the images of the two cameras 11a and 11d that capture both ends of the panoramic image shown in FIG. 22 are continuous with the images captured by the other cameras 11b and 11c in the horizontal direction. It is an angle. In other words, if the two cameras that capture both ends of the panoramic image are rotated to one of the left and right directions to the maximum rotation angle, the images of the remaining two cameras and the horizontal direction can be made continuous.

  The cameras 11a to 11d are not rotated beyond the maximum rotation angle by the stopper mechanism (for example, the lever 72 and the stopper portions 83a and 83b described in FIG. 17). Therefore, in the two cameras that capture both ends of the panoramic image, the horizontal direction of the panoramic image can be made continuous by rotating it to the maximum rotation angle. For example, the two cameras 11a and 11d that capture both ends of the panoramic image shown in FIG. 22 may be rotated in either the left or right direction until the rotation is stopped by the stopper mechanism. That is, the user can easily adjust the panoramic image to be continuous in the horizontal direction.

  Note that, for two cameras sandwiched between two cameras that capture both ends of the panoramic image, for example, a mark indicating a rotation angle for the panoramic image to be horizontal may be attached to the back of the cover 83. For example, the user rotates the camera until the mark on the back of the cover 83 comes to the position of the claw 72a of the lever 72, so that images sandwiched between the images at both ends of the panoramic image are continuously displayed in the horizontal direction. can do.

  In the above description, the panoramic images by the four cameras 11a to 11d have been described, but the present invention can also be applied to the panoramic images by the three cameras. For example, as shown in FIG. 20, the present invention can also be applied to a case where one camera 11a is directed toward the zenith of the cover 2 and panoramic images are taken with the remaining cameras 11b to 11d. The maximum rotation angle in this case is different from the maximum rotation angle of the panoramic image by the four cameras.

  The surveillance camera may be impacted from the outside. The surveillance camera of the present case has a mechanism for mitigating external impacts.

  FIG. 25 is a diagram for explaining a mechanism for reducing the impact from the outside of the surveillance camera. In FIG. 25, the same components as those in FIG. In FIG. 25, the cameras 11a to 11d are not shown.

  The surveillance camera indicated by arrow A112 in FIG. 25 is a cross-sectional view taken along the line CC of the surveillance camera indicated by arrow A111. The surveillance camera indicated by arrow A113 in FIG. 25 is a cross-sectional view taken along the arrow D-D of the surveillance camera indicated by arrow A111. As shown in FIG. 25, the surveillance camera has a guide 111 that regulates the movement of the base 12.

  The base 12 is biased in the direction of the cover 2 (+ z-axis direction) by a biasing member (not shown) such as a spring, for example. The base 12 is regulated by the guide 111 so as not to come out of the housing 1.

  The guide 111 has a groove whose width increases as it goes toward the bottom of the housing 1, as shown in the CC cross-sectional view.

  A part (protrusion) of the base 12 is received in the groove of the guide 111. The protrusion 112 shown in the CC cross-sectional view shows the protrusion of the base 12 that fits in the groove of the guide 111 in the CC cross-sectional view.

  The groove of the guide 111 becomes narrower as it goes in the direction of the cover 2. The width of the narrowest groove is narrower than the width of the protrusion 112 of the base 12. As a result, the base 12 does not come out of the housing 1.

  The protrusion 112 of the base 12 can move freely within the range of the groove of the guide 111. As described above, the width of the groove of the guide 111 becomes wider toward the bottom of the housing 1. Accordingly, the degree of freedom of movement of the base 12 increases toward the bottom of the housing 1.

  The surveillance camera has screws 113a to 113d. The screws 113 a to 113 d pass through a hole formed in the base 12 and are fixed to the housing 1. The diameters of the heads of the screws 113 a to 113 d are larger than the diameters of the holes formed in the base 12. Further, the diameter of the cylindrical portion of the screws 113 a to 113 d is smaller than the diameter of the hole formed in the base 12. Accordingly, the base 12 is prevented from coming out of the housing 1 by the heads of the screws 113a to 113d. Moreover, since the diameter of the hole formed in the base 12 is larger than the diameter of the cylindrical portion of the screws 113a to 113d, the hole can sink into the housing 1 in an inclined state (see FIG. 27B).

  FIG. 26 is a diagram illustrating a state in which the base 12 is sunk toward the bottom of the housing 1. 26 is a cross-sectional view taken along the line CC of the monitoring camera shown in FIG. In FIG. 26, the same components as those in FIG. 25 are denoted by the same reference numerals.

  For example, when an impact is applied from the outside of the cover 2, the base 12 sinks toward the bottom of the housing 1. For example, the protrusion 112 of the base 12 moves toward the bottom of the housing 1 as shown in FIG. Thereby, the surveillance camera can disperse the force applied to the cameras 11a to 11d. The base 12 is returned to the original position by the biasing member.

  As described with reference to FIG. 25, the degree of freedom of movement of the base 12 increases toward the bottom of the housing 1. Therefore, the base 12 can disperse the force even if the force is applied from various directions.

  27A and 27B are views showing a state in which the base 12 sinks toward the bottom of the housing 1. 27A and 27B are DD cross-sectional views of the surveillance camera shown in FIG. 27A and 27B, the same components as those in FIG. 25 are denoted by the same reference numerals.

  FIG. 27A shows the state of the base 12 when a force is evenly applied to the entire base 12. When force is evenly applied to the entire base 12, the entire base 12 sinks toward the bottom of the housing 1 as shown in FIG. 27A.

  FIG. 27B shows the state of the base 12 when a force is applied to a part of the base 12. When a force is applied to a part of the base 12, as shown in FIG. 27B, the portion where the force is applied sinks toward the bottom of the housing 1. As described with reference to FIG. 25, the groove of the guide 111 is formed so that the width becomes wider toward the bottom of the housing 1. Therefore, as illustrated in FIG. 27B, the base 12 is inclined. It can sink toward the bottom of the housing 1. That is, the base 12 can disperse forces applied from various directions.

  The overhanging portion (庇) provided around the lens 61 shown in FIGS. 14 and 16 will be described. The cameras 11a to 11d are movable and are arranged at various positions. For example, the cameras 11a to 11d are arranged as shown in FIG. The cameras 11a to 11d are downsized so as to be arranged at various positions.

  When the cameras 11a to 11d are downsized, the light passing through the cover 2 increases. Then, the light traveling from the rear of the lens 61 of the cameras 11 a to 11 d to the front of the lens 61 may be reflected by the inner surface of the cover 2 in front of the lens 61 and may enter the lens 61. When the reflected light is incident on the cameras 11a to 11d, an image including a subject that should not be projected may be output from the surveillance camera.

  Therefore, the surveillance camera includes an overhanging portion that blocks the reflected light reflected by the inner surface of the cover 2 from entering the cameras 11a to 11d.

  FIG. 28 is a perspective view of a surveillance camera provided with an overhanging portion. In FIG. 28, the same components as those in FIGS. 2 and 3 are denoted by the same reference numerals.

  As shown in FIG. 28, each of the cameras 11a to 11d has overhang portions 121a to 121d. The overhang portions 121a to 121d are, for example, plate-shaped and have a circular shape.

  The overhang portions 121a to 121d are formed of, for example, a flexible resin. Even if the surveillance camera receives an impact from the outside, and the overhanging portions 121a to 121d collide with the cover 2 due to the impact, the overhanging portions 121a to 121d have flexibility so that the overhanging portions 121a to 121d and the cover 2 damage can be suppressed.

  The color of the overhang portions 121a to 121d is, for example, black. By making the overhang portions 121a to 121d black, the overhang portions 121a to 121d are reflected (reflected) on the cover 2, and the overhang portions 121a to 121d themselves can be prevented from being reflected on the cameras 11a to 11d. .

  FIG. 29A is an exploded perspective view of the camera 11a and the overhang portion 121a. As illustrated in FIG. 29A, the camera 11 a includes a main body portion 131 and a lens portion 132.

  The lens part 132 has a cylindrical shape and protrudes from the main body part 131. The overhanging portion 121 a has a circular opening 122. A cylindrical lens portion 132 is inserted into the opening 122 of the overhang portion 121a. The overhanging part 121 a is fixed to the lens part 132 by inserting the lens part 132 into the opening part 122.

  FIG. 29B is a perspective view when the overhanging part 121a is attached to the camera 11a. In FIG. 29B, the same components as those in FIG. 29A are denoted by the same reference numerals.

  As described with reference to FIG. 29A, the protruding portion 121 a is fixed to the lens portion 132 by inserting the lens portion 132 into the opening 122. The overhang portion 121 a is disposed around the cylindrical lens portion 132 and extends in the radial direction of the lens portion 132. For example, the overhanging part 121a extends in the direction indicated by the dotted arrow A121 in FIG. 29B (the radial direction of the lens part 132).

  Note that the overhang portions 121b to 121d provided in the cameras 11b to 11d shown in FIG. 28 have the same shape as the overhang portion 121a described with reference to FIGS. 29A and 29B, and the description thereof is omitted. .

  FIG. 30A is a perspective view of the protruding portion 121a as viewed from the front (the cover 2 side). In FIG. 30A, the same components as those in FIGS. 29A and 29B are denoted by the same reference numerals. As shown in FIG. 30A, the surface S1 facing the cover 2 of the overhang portion 121a is substantially flat (as described in FIG. 30D, the surface S1 is slightly curved).

  FIG. 30B is a perspective view of the overhang portion 121a as seen from the rear. In FIG. 30B, the same components as those in FIG. 30A are denoted by the same reference numerals. A cylindrical portion 123 is formed on the rear side of the overhang portion 121a. The overhanging portion 121a is formed with a circular flange portion 124. The collar portion 124 extends in the direction toward the center of the opening 122 and is formed on the surface S1 side of the opening 122.

  The tip of the lens part 132 shown in FIG. 29A is passed through the tube part 123. The tip of the lens part 132 is passed to the collar part 124. Thereby, the overhang part 121a is fixed to the lens part 132 of the camera 11a.

  FIG. 30C is a front view of the overhang portion 121a. In FIG. 30C, the same components as those in FIG. 30A are denoted by the same reference numerals. As illustrated in FIG. 30C, the overhang portion 121a has a circular outer shape. The opening 122 also has a circular shape.

  30D is a cross-sectional view taken along line AA in FIG. 30C. In FIG. 30D, the same components as those in FIGS. 30A, 30B, and 30C are denoted by the same reference numerals. FIG. 30D also shows the lens portion 132 shown in FIG. 29A.

  The overhanging part 121a is pushed in until the tip of the lens part 132 comes to the position of the collar part 124 (see also the collar part 124 in FIG. 30B). Thereby, the surface S1 of the overhanging portion 121a is substantially flush with the surface of the lens portion 132 facing the cover 2.

  The surface S1 of the overhang portion 121a is curved along the curved surface of the cover 2 (see, for example, the cover 2 and the overhang portion 121a in FIG. 31). The surface S1 of the overhang portion 121a is curved so as to go downward in the figure as it goes toward the end.

  FIG. 31 is a diagram illustrating reflected light incident on the camera 11a. In FIG. 31, the same components as those in FIGS. 29A and 29B are denoted by the same reference numerals. FIG. 31 shows the cover 2.

  The overhanging portion 121a has such a size that the reflected light reflected from the inner surface of the cover 2 of the light traveling from the rear to the front of the lens portion 132 does not enter the angle of view of the camera 11a.

  For example, a line A131 shown in FIG. 31 indicates the angle of view of the camera 11a. A dotted line A132 shown in FIG. 31 indicates incident light that matches the angle of view. The overhanging portion 121a has such a size that the reflected light of the light indicated by the dotted line A132 does not enter the angle of view of the camera 11a (lens portion 132). The incident light indicated by the dotted line A133 is not reflected on the camera 11a because it is outside the angle of view of the camera 11a. Incident light indicated by a dotted line A134 is within the angle of view of the camera 11a, but is blocked by the overhanging portion 121a.

  In this way, the camera 11a is prevented from entering unnecessary reflected light by the protruding portion 121a. Thereby, the surveillance camera can output an appropriate image.

  In addition, as described with reference to FIG. 30D, the surface S1 of the overhang portion 121a is substantially flush with the surface of the lens portion 132 that faces the cover 2. Thereby, the overhang part 121a and the lens part 132 can be brought close to the cover 2. For example, the distance of the double arrow A135 shown in FIG. 31 can be shortened. By bringing the overhanging part 121a and the lens part 132 close to the cover 2, the camera 11a blocks the incidence of unnecessary reflected light without enlarging the overhanging part 121a. In addition, since the overhang portion 121a can be reduced, interference with the overhang portions 121b and 121d provided in the adjacent cameras 11b and 11d can be suppressed, and the movable range of the cameras 11a to 11d can be increased.

  In addition, as described with reference to FIG. 30D, the surface S <b> 1 of the overhang portion 121 a is curved along the curved surface of the cover 2. Thereby, the overhang part 121a and the lens part 132 can be brought close to the cover 2. For example, the distance of the double arrow A135 shown in FIG. 31 can be shortened. By bringing the overhanging part 121a and the lens part 132 close to the cover 2, the camera 11a blocks the incidence of unnecessary reflected light without enlarging the overhanging part 121a. In addition, since the overhang portion 121a can be reduced, interference with the overhang portions 121b and 121d provided in the adjacent cameras 11b and 11d can be suppressed, and the movable range of the cameras 11a to 11d can be increased.

  FIG. 32A is a perspective view of a protruding portion having another shape as viewed from the front. FIG. 32B is a perspective view of the overhang portion of FIG. 32A as viewed from the rear. As shown in FIGS. 32A and 32B, the overhang 141 has an opening 141a. The lens portion 132 of the camera 11a is inserted into the opening 141a. Thereby, the overhang | projection part 141 is fixed to the lens part 132 of the camera 11a.

  A surface S11 of the overhanging portion 141 facing the cover 2 is curved along the curved surface of the cover 2. Even if the overhanging portion 141 has the shape shown in FIGS. 32A and 32A, it can block the incidence of unnecessary reflected light on the camera 11a.

  FIG. 33A is a perspective view of a protruding portion having another shape as viewed from the front. FIG. 33B is a perspective view of the overhang portion of FIG. 33A viewed from the rear. As shown in FIGS. 33A and 33B, the overhang 142 has an opening 142a. The lens portion 132 of the camera 11a is inserted into the opening 142a. Thereby, the overhang | projection part 142 is fixed to the lens part 132 of the camera 11a.

  The edge of the overhanging portion 142 has a shape protruding from the lens portion 132 toward the cover 2 side. Even if the overhanging portion 142 has the shape shown in FIGS. 33A and 33B, it can block the incidence of unnecessary reflected light on the camera 11a.

  FIG. 34A is a perspective view of a protruding portion having another shape as viewed from the front. FIG. 34B is a perspective view of the overhang portion of FIG. 34A viewed from the rear. As shown in FIGS. 34A and 34B, the overhang portion 143 has an opening 143a. The lens portion 132 of the camera 11a is inserted into the opening 143a. Thereby, the overhang | projection part 143 is fixed to the lens part 132 of the camera 11a.

  The overhang portion 143 has a plate shape. Even if the overhanging portion 143 has the shape shown in FIGS. 34A and 34B, it can block incidence of unnecessary reflected light to the camera 11a.

  FIG. 35 is a diagram showing another example of the attachment position of the overhang portion. 35, the same components as those in FIG. 31 are denoted by the same reference numerals. In FIG. 35, a circular plate-like overhang 151 is attached to the camera 11a.

  Unlike the surface S1 of the overhanging part 121a shown in FIG. 31, the surface S21 of the overhanging part 151 facing the cover 2 is not flush with the surface of the lens part 132 facing the cover 2. The overhang portion 151 is provided at the base of the lens portion 132 with the main body portion 131 and is separated from the cover 2.

  Thus, even if the overhanging portion 151 is provided at a position close to the main body portion 131, it is possible to block unnecessary reflected light from entering the camera 11a. However, since the overhanging portion 151 is separated from the cover 2, the overhanging portion 151 is larger than the overhanging portion 121a shown in FIG. 31 in order to block the incidence of unnecessary reflected light.

  FIG. 36 is an exploded perspective view of the camera 11a and the overhanging portion 121a capable of zoom adjustment and focus adjustment. 36, the same components as those in FIG. 29A are denoted by the same reference numerals.

  The camera 11a may be capable of zoom adjustment and focus adjustment. As shown in FIG. 36, the lens unit 132 of the camera 11a includes an adjustment unit 161 that adjusts the zoom and an adjustment unit 162 that adjusts the focus. The adjustment units 161 and 162 are, for example, knobs, and adjust the zoom and focus of the camera 11a by being rotated.

  The cylinder part 123 (for example, see FIG. 30B) of the overhang part 121a has a hole through which the adjustment parts 161 and 162 pass. Thereby, the adjustment parts 161 and 162 protrude from the cylinder part 123 and can be rotated. For example, as shown by arrows A141a and 141b in FIG. 28, the adjusting portions 161 and 162 can protrude from the cylindrical portion 123 and can be rotated.

  As described above, the adjusting units 161 and 162 for adjusting the zoom and focus of the camera 11a are arranged between the overhanging portion 121a and the main body 131 of the camera 11a. Thereby, the user can easily adjust the zoom and focus of the camera 11a. For example, the user can easily adjust the zoom and focus of the camera 11a by inserting a jig or a finger that rotates the adjusting units 161 and 162 between the overhanging part 121a and the main body part 131 of the camera 11a.

  In the camera 11a, at least one of zoom and focus may be adjusted. That is, the camera 11a may include at least one of the adjustment units 161 and 162.

  Although the shape of the overhang | projection parts 121a-121d, 141-143, 151 is circular shape, it is not restricted to this. The overhang portions 121a to 121d, 141 to 143, and 151 may be, for example, quadrangular or elliptical as long as the reflected light does not enter the cameras 11a to 11d.

  Since the surveillance camera blocks the incident of the reflected light to the cameras 11a to 11d by the overhang portions 121a to 121d, 141 to 143, 151, parts other than the overhang portions 121a to 121d, 141 to 143, 151 are other than black Can be any color. For example, the color of the camera 11a movable in the zenith direction of the cover 2 is set to a color other than black, and the color of other components is set to black. Thereby, it becomes easy to distinguish between the camera 11a that is movable in the zenith direction of the cover 2 and the cameras 11b to 11d that are not movable in the zenith direction of the cover 2.

  As described above, the dome-type surveillance camera has the base 12, the connecting members 21 aa, 21 ab, 21 b, 21 c, and 21 d connected to the base 12, and the photographing direction is movable in the elevation angle direction with respect to the base 12. The plurality of cameras 11a to 11d connected to the connecting members 21aa, 21ab, 21b, 21c, and 21d, and fixed to the base 12 so as to cover the connecting members 21aa, 21ab, 21b, 21c, and 21d and the plurality of cameras 11a to 11d. A dome-shaped cover 2. One camera 11 a among the plurality of cameras 11 a to 11 d is movable so that the shooting direction faces the zenith of the cover 2.

  As a result, the surveillance camera can direct the photographing direction in various directions. For example, the surveillance camera can point the photographing direction vertically below the ground. Further, since the surveillance camera can direct the photographing direction in various directions, for example, it is possible to clearly photograph a vertically lower part of the ground or the like. Moreover, the monitoring camera can display the vertically lower side of the ground or the like at the center of the display device, for example.

  In addition, the dome-type surveillance camera is connected to the base 12, the connecting members 21aa, 21ab, 21b to 21d connected to the base 12, and the cameras 11a to 11d connected to the connecting members 21aa, 21ab, 21b to 21d. A dome-shaped cover 2 fixed to the base 12 so as to cover the members 21aa, 21ab, 21b to 21d and the cameras 11a to 11d. The base 12 includes a circular rail 41 centered at a position directly below the zenith of the cover 2, the connecting members 21 b to 21 d slide along the rail 41, and the connecting members 21 aa and 21 ab are connected to the cover 2. It is connected to the base 12 directly under the zenith.

  As a result, the surveillance camera can direct the photographing direction in various directions. For example, the surveillance camera can direct the photographing direction in various azimuth directions by the cameras 11b to 11d sliding on the rail 41. In addition, the surveillance camera can point the camera 11a toward the top of the cover 2, and can direct the shooting direction vertically below the ground, for example.

  The dome-type surveillance camera includes a base 12, a connecting member 21aa, 21ab, 21b, 21c, 21d connected to the base 12, and a plurality of cameras connected to the connecting members 21aa, 21ab, 21b, 21c, 21d. 11a to 11d and a dome-shaped cover 2 fixed to the base 12 so as to cover the connecting members 21aa, 21ab, 21b, 21c and 21d and the plurality of cameras 11a to 11d. Each of the plurality of cameras 11a to 11d is connected to the connecting members 21aa, 21ab, 21b, 21c, so as to be rotatable to a predetermined rotation angle in both the left and right directions with the shooting direction as an axis so that the panoramic images to be shot are continuous in the horizontal direction. The predetermined rotation angle is an angle at which two of the cameras 11a to 11d, which capture both ends of the panoramic image, are continuous with the images captured by the other cameras in the horizontal direction. .

  Thereby, the surveillance camera can easily adjust the cameras 11a to 11d so that the panoramic images are continuous in the horizontal direction. For example, the user may rotate the cameras 11a to 11d that capture both ends of the panoramic image to a predetermined rotation angle.

  The dome-type surveillance camera includes a base 12, a plurality of cameras 11a to 11d connected to the base 12, and a dome-type cover 2 fixed to the base 12 so as to cover the plurality of cameras 11a to 11d. , Provided around each lens 61 of the plurality of cameras 11a to 11d, and extending portions 121a to 121d extending in the radial direction of the lens. The reflected light reflected by the inner surface of the cover 2 of the light traveling forward has such a size that it does not enter the angle of view of the cameras 11a to 11d.

  Thereby, the surveillance camera can block the incidence of the light reflected by the inner surface of the cover 2 on the lens 61 and output an appropriate image.

  Although the shooting directions of the cameras 11a to 11d are adjusted by the user's hand, the present invention is not limited to this. For example, the surveillance camera may have a drive device that can remotely control the shooting directions of the cameras 11a to 11d.

  The present disclosure is useful as a dome-type surveillance camera.
