Description

[Technical Field]

[0001] The present invention relates to an imaging device, and more particularly to an imaging device suitable for use in a surveillance camera, for general-purpose power supply connection and signal connection of a device having a video processing unit on a base. [Background technology]

[0002] Pan-tilt imaging devices used in surveillance cameras have a video processing unit that processes high-speed video signals received from the onboard imaging unit. This video processing unit converts the video signal into a signal that matches the transmission method for external output, and there are several transmission methods for external output of the signal, such as radio wave transmission and optical fiber transmission. To accommodate these multiple transmission methods, the video processing unit of the imaging device is unitized, with a configuration in which the video processing unit can be replaced to match each transmission method, and is mounted by being inserted into a base.

[0003] The image processing unit has a power connector in addition to a video connector for receiving high-speed image signals from the imaging unit. The power connector is used to supply power obtained by the imaging device from an external power source to the image processing unit via a power supply unit inside the imaging device.

[0004] Because the power connector and video connector are included in the video processing unit, the connection to the imaging device is interrupted when the unit is replaced, so the connectors must be reconnected after the unit is replaced.

[0005] Generally, power cables are connected using, for example, a D-sub (D-subminiature) connector, where one terminal is a male and the corresponding terminal is a female terminal that are mated together to supply power.

[0006] On the other hand, for example, the SDI (Serial Digital Interface) standard, which transmits high-speed video signals, transmits signals via coaxial cable and uses a BNC (Bayonet Neill Concelman) connector for connection.To connect a BNC connector, the conductive center contact is inserted, and the outer periphery is rotated and locked or screwed in.

[0007] A connection between a signal cable and a power cable for a surveillance camera is disclosed, for example, in Patent Document 1. Patent Document 1 discloses that the connector for connecting the power cable and the signal cable is integrally molded (Fig. 2: second connector), which makes installation easier.

[0008] The configuration of a recording medium unit of a video recording device is disclosed in Patent Document 2. The recording medium unit of Patent Document 2 includes a power terminal 111 for HDD and a signal terminal 112 for HDD.

[0009] Furthermore, in the technology described in Patent Document 3, an E / O converter is installed within the structure of the pan head device, and a connector (HD-SDI connector) for connecting a signal cable to the structure is provided. [Prior art documents] [Patent documents]

[0010] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-234925 [Patent Document 2] Japanese Patent Application Laid-Open No. 2010-157300 [Patent Document 3] Japanese Patent Application Laid-Open No. 2005-260304 Summary of the Invention [Problem to be solved by the invention]

[0011] In the signal cable and power cable of a surveillance camera of the prior art, the camera body is connected to the outside world using separate connectors (a signal connector and a power connector), as shown in Figure 8 of Patent Document 1. With this connection, power is supplied to the camera through the power cable connected to the power connector, and a video signal is transmitted to the outside world through the signal cable connected to the signal connector.

[0012] Here, when mounting a power connector and a signal connector on the imaging device, if the power connector and the signal connector are mounted on the insertion surface of the video processing unit as in Patent Document 2, it becomes difficult to use a rotary connector such as a BNC as the signal connector. Similarly, the configuration of the surveillance camera shown in Figures 1 and 2 of Patent Document 1 also makes it impossible to use a rotary connector such as a BNC as the signal connector. Therefore, it becomes difficult to connect a BNC connector, which transmits high-speed signals, using a coaxial cable.

[0013] An object of the present invention is to provide an imaging device that includes a video processing unit on a base, that allows general-purpose power supply connections and signal connections, and that is capable of high-speed signal transmission. [Means for solving the problem]

[0014] The configuration of the imaging device of the present invention is preferably an imaging device comprising an imaging section, a head section that holds the imaging section and has a power supply unit, and a base section that holds the head section, wherein the base section has an outer case section fixed therein, and comprises a signal cable extending from the imaging section to the outer case section, a power cable extending from the power supply unit to the outer case section, and a video processing unit that can be inserted into the outer case section and has a video processing circuit, the video processing unit having an insertion surface that is inserted into the outer case section in the insertion direction and an exposed surface that is exposed to the outside after insertion, the insertion surface of the video processing unit having a power connector that engages with a connector provided at the end of the power cable along the insertion direction, and the exposed surface of the video processing unit having a signal connector that engages with a connector provided at the end of the signal cable. [Effects of the Invention]

[0015] According to the present invention, an imaging device having a video processing unit on a base can be provided that allows general-purpose power supply connections and signal connections and is capable of high-speed signal transmission. [Brief explanation of the drawings]

[0017] Hereinafter, each embodiment of the present invention will be described with reference to FIGS. 1A to 8. FIG.

[0018] [Embodiment 1]

[0019] A first embodiment of the present invention will be described below with reference to FIGS. 1A to 7. FIG. First, the overall appearance of the imaging device will be described with reference to FIGS. 1A and 1B. FIG. 1A is a perspective view (part 1) of an imaging device according to the first embodiment. FIG. 1B is a perspective view (part 2) of the imaging device according to the first embodiment.

[0020] As shown in Fig. 1A, the imaging device is composed of an imaging unit 1, a housing unit 2, a head unit 3, a base unit 4, and an image processing unit 5. The imaging unit 1 is a camera that supports high-speed video signal transmission and is housed inside the housing unit 2. The housing unit 2 is held by the head unit 3. The housing unit 2 can be rotated in a tilt direction (vertical direction) by a tilt drive unit (not shown) built into the head unit 3.

[0021] The head unit 3 is held by a base unit 4. The head unit 3 can be rotated in the pan direction (horizontal direction) by a built-in pan drive unit (not shown).

[0022] The head unit 3 also includes a power supply unit 6 (described later in FIG. 2) inside. This power supply unit 6 converts electricity from an external power supply from AC voltage to DC voltage, and serves to supply power to the electrical components housed in the housing unit 2, head unit 3, and base unit 4.

[0023] The base 4 houses the image processing unit 5, which can be replaced in the event of a malfunction or when upgrading functions. The image processing unit 5 is a unitized image processing circuit that converts high-speed video signals received from the imaging unit 1 into appropriate external output signals. There are multiple types of image processing units 5, each equipped with different types of external connectors 47 according to the external signal transmission method, as shown in FIG. 1B . The external connectors 47 are connected to external devices by engaging with corresponding connectors, and serve functions such as external power supply and video signal output. By using an image processing unit 5 equipped with the appropriate type of external connector 47 depending on the application, the imaging device can output processed signals to the outside via radio wave transmission or optical fiber transmission.

[0024] Next, a cross section of the imaging device will be described with reference to FIG. 2 is a cross-sectional view of the main part of the imaging device, in which part of the base part 4 is omitted.

[0025] As described above, the imaging unit 1 supports high-speed transmission of video signals, and as shown in FIG. 2, a high-speed video signal cable 7 is connected to it. The high-speed video signal cable 7 passes from the housing unit 2 to the head unit 3 via a housing through-hole 8 that penetrates the side of the housing unit 2 and a tilt axis through-hole 9 that penetrates the center of the tilt rotation axis on the side of the head unit 3. The high-speed video signal cable 7 that has passed through the head unit 3 passes through a pan axis through-hole 10 that penetrates the center of the pan rotation axis of the head unit 3 and a base top surface opening 11 provided on the head holding surface 21 of the base unit 4, and then passes inside the base unit 4. The high-speed video signal cable 7 that has passed through the base unit 4 is connected to the video processing unit 5 (the detailed structure of which will be described later: FIGS. 5, 6A, and 6B).

[0026] The head unit 3 also includes a power supply unit 6 that functions as an AC-DC converter that converts externally supplied electricity from AC voltage to DC voltage. The power supply unit 6 is provided on an inner wall surface 14 of the head unit 3. The electricity converted by the power supply unit 6 is sent to electronic boards (not shown) housed inside the housing unit 2 and the head unit 3, and to the image processing unit 5 inside the base unit 4. A power cable 15 connected to the power supply unit 6 is used to supply power to the image processing unit 5. The power cable 15 is passed through the pan axis through-hole 10 and the base top opening 11 and into the inside of the base unit 4. The power cable 15 that has passed through the base unit 4 is connected to the image processing unit 5.

[0027] Next, the structure of the base will be described with reference to FIGS. 3A and 3B. FIG. 3A is an exploded perspective view of the base part (part 1). FIG. 3B is an exploded perspective view of the base portion (part 2).

[0028] As shown in Fig. 3A, the base 4 is composed of a base main body 18, an outer case 19, and a bottom plate 20. The base main body 18 is a convex-shaped cast part with an internal space. The base main body 18 has a head holding surface 21 that holds the head unit 3, and a base top surface opening 11 that connects to the internal space. The base main body 18 also has a base bottom surface opening 23 that connects to the internal space, and a bottom surface 22 that faces the head holding surface 21. The base main body 18 also has an insertion surface opening 25 that connects to the internal space, and a receiving surface 24 into which the video processing unit 5 is inserted.

[0029] As shown in FIG. 3B, base main body 18 has a plurality of screw holes 27 for fixing outer case 19 to a top surface 26 of the internal space. Outer case 19 is fixed to fixing screw holes 27 with screws via fixing holes 32 (described below in FIG. 4) in outer case 19. A bottom plate 20 is attached to a bottom surface 22 of base main body 18. With this configuration, after outer case 19 is fixed by screws, base bottom opening 23 can be closed by bottom plate 20.

[0030] Next, the structure of the outer case to which the power cable is connected will be described with reference to FIG. FIG. 4 is a perspective view of the outer case to which the power cable is connected.

[0031] The outer case 19 is a box-shaped sheet metal unit that is open only at an opening 28. A top surface 29 of the outer case 19 has a top surface through-hole 31 through which a high-speed video signal cable 7 (described later in FIG. 7) passes.

[0032] Additionally, the top surface 29 of the outer case portion 19 has a plurality of fixing holes 32 corresponding to the above-mentioned fixing screw holes 27. Fixing screws (not shown) are fastened to the fixing screw holes 27 via the fixing holes 32, whereby the outer case portion 19 is fixed to the base main body portion 18 shown in FIGS. 3A and 3B.

[0033] Furthermore, a female power connector 16 is provided at the tip of the power cable 15, and is adapted to engage with a male power connector 17 (described later in FIG. 7) of the video processing unit 5 on the back surface 33 of the outer case 19. The power connector is, for example, a D-sub DB-25 connector. The power cable 15 is passed through the inside of the base 4 along the path described with reference to FIG. 1B and routed along the top surface 29 and side surface 30 of the outer case 19. With this routing, when the outer case 19 is fixed to the base main body 18, the power cable 15 is housed between the side surface 30 of the outer case 19 and the inner wall surface inside the base main body 18. After this routing, the female power connector 16 at the tip of the power cable 15 is fixed to the back surface 33 with a screw. The power supply female connector 16 engages with the power supply male connector 17 (described later: Figure 7) of the video processing unit 5 described later when it is inserted linearly from the open portion 28 side, and is electrically connected to the video processing unit 5 equipped with the power supply male connector 17.

[0034] Furthermore, a fixing surface 34 extending to the outside of the outer case part 19 is provided in the open part 28 facing the rear surface 33. The fixing surface 34 has a plurality of fixing screw holes 35 used for fixing to the video processing unit 5 described later.

[0035] Next, the relationship between the base and the image processing unit will be described with reference to FIG. FIG. 5 is an exploded perspective view showing the state before the video processing unit is inserted into the base portion.

[0036] As shown in Fig. 5, the image processing unit 5 can be inserted into the outer case 19 through the insertion surface opening 25 of the base 4 shown in Fig. 3B. After being inserted in this manner, the image processing unit 5 is fixed by screws into the fixing screw holes 35 via the exposed surface through-holes 46 of the image processing unit 5.

[0037] Next, the structure of the video processing unit will be described in detail with reference to FIGS. 6A and 6B. FIG. 6A is a side view of the video processing unit. FIG. 6B is a perspective view of the video processing unit.

[0038] As shown in FIG. 6A , the video processing unit 5 is composed of an inner case 36, a video processing section 37, and an optical conversion processing section 38. The inner case 36 is a box-shaped sheet metal unit. The inner case 36 holds the video processing section 37 on its inner surface 39. The video processing section 37 is implemented as an electronic board having electrical elements and connectors, and converts video signals into appropriate signals for external output. The inner case 36 also has a standing wall 40 provided parallel to the inner surface 39. The standing wall 40 is a sheet metal part extending vertically from a top surface 41 and a bottom surface 42 of the inner case 36, and holds the optical conversion processing section 38. The optical conversion processing section 38 is an electronic board having electrical elements and connectors, and converts video signals into optical signals for optical fiber transmission.

[0039] The inner case 36 also has an insertion surface 43 that is inserted into the base 4. A male power connector 17 that engages with the female power connector 16 at the end of the power cable 15 attached to the outer case 19 is fixed by screws to the insertion surface 43. The male power connector 17 is electrically connected to the video processing unit 37 and the light conversion processing unit 38.

[0040] Furthermore, the inner case portion 36 has an exposed surface 44 that faces the insertion surface 43 and is exposed to the outside when inserted into the base portion 4. The exposed surface 44 has an opening 45 through which the high-speed video signal cable 7 (described later: FIG. 7) passes. The opening 45 is located on a side surface that is outward from the top surface 41.

[0041] 6B, the exposed surface 44 has exposed surface through-holes 46 used to fix the image processing unit 5 inside the base 4. The image processing unit 5 is fixed to the fixing screw holes 35 of the outer case 19 by screws via the exposed surface through-holes 46.

[0042] The exposed surface 44 also holds an external connector 47 and a high-speed signal male connector 13 .

[0043] The external connection connector 47 and the high-speed signal male connector 13 have their engaging portions with the corresponding connectors exposed to the outside. Although not specifically shown in the present embodiment, the external connection connector 47 is connected to an external device by engaging with a corresponding connector, and serves to supply external power and output video signals. On the other hand, the high-speed signal male connector 13 is connected to the imaging unit 1 by engaging with a corresponding connector, and serves to receive high-speed video signals. The external connection connector 47 and the high-speed signal male connector 13 are both electrically connected to the video processing unit 37 and the optical conversion processing unit 38.

[0044] Next, referring to FIG. 7, the manner in which the video processing unit is housed in the base and the power cable and high-speed signal cable are connected will be described. FIG. 7 is a cross-sectional view of the image processing unit housed in the base and connected to a power cable and a high-speed signal cable.

[0045] As shown in Fig. 4, power cable 15 for supplying power is routed along a route that runs along top surface 29 and side surface 30 of outer case 19, and female power connector 16 at the end of power cable 15 is fixed to rear surface 33 with screws. As described above, female power connector 16 has a mechanism that allows it to engage with a corresponding connector when inserted from one direction. Then, as shown in Fig. 7, video processing unit 5 having male power connector 17 is inserted linearly into base 4 from insertion surface 24 side into female power connector 16 at the end of power cable 15, allowing these connectors to engage with each other.

[0046] By engaging the female power connector 16 and the male power connector 17 in this manner, power is supplied to the video processing unit 37 and the optical conversion processing unit 38, which are electrically connected to the male power connector 17. The video processing unit 37, to which power is supplied, converts the high-speed video signal received via a path described below into a signal that can be output externally via radio waves. As mentioned above, video transmission methods include optical fiber transmission in addition to radio wave transmission. When optical fiber transmission is used, the optical conversion processing unit 38, to which power is supplied, receives the high-speed video signal from the video processing unit 37 and converts it into an optical signal. The high-speed video signal processed in this manner is output to an external device from the external connection connector 47, which is electrically connected to the video processing unit 37 or the optical conversion processing unit 38.

[0047] Next, the flow up to when the video processing unit 37 and the optical conversion processing unit 38 receive the high-speed video signal will be described together with the method of routing the high-speed video signal cable 7.

[0048] The high-speed video signal cable 7, which transmits high-speed video signals from the imaging unit 1, passes through the base top opening 11 of the base unit 4 and is passed through the top through-hole 31 provided in the top surface 29 of the outer case unit 19. After passing through the top through-hole 31, the high-speed video signal cable 7 is routed between the top surface 29 of the outer case unit 19 and the top surface 41 of the inner case unit 36, and is exposed to the outside through the opening 45 of the exposed surface 44. In other words, the high-speed signal cable 7 is routed along a path that passes through the space between the outer case unit 19 and the video processing unit 5 and is exposed to the outside.

[0049] Here, the exposed surface 44 has a high-speed signal male connector 13 with an engaging portion exposed to the outside. The high-speed signal male connector 13 has a mechanism in which, after insertion into a corresponding connector, the person installing the device rotates the plug in the direction of a rotation axis extending in the insertion direction, thereby engaging the connectors. The high-speed signal male connector 13 is, for example, a BNC connector plug. The high-speed signal female connector 12 at the tip of the high-speed video signal cable 7, which is also exposed to the outside, can be engaged with the high-speed signal male connector 13 having such a mechanism by rotating it. The high-speed signal female connector 12 is, for example, a BNC connector jack. By engaging the connectors in this way, the high-speed video signal cable 7 is electrically connected to the video processing unit 5, enabling transmission of high-speed video signals from the imaging unit 1 to the video processing unit 5.

[0050] As described above, according to this embodiment, in an imaging device capable of directly transmitting high-speed video signals from an imaging unit to an external device, cable connection to two types of connectors with different insertion methods that an exchangeable video processing unit has becomes possible. That is, a power connector can be inserted into the insertion surface of the video processing unit that is inserted into the base, and high-speed signals can be transmitted to one exposed surface using a high-speed signal connector in a coaxial cable.

[0051] [Embodiment 2]

[0052] Hereinafter, a second embodiment of the present invention will be described with reference to FIG. FIG. 8 is a bird's-eye view of the high-speed video signal cable connected to the video processing equipment.

[0053] Depending on the environment in which the imaging device is used, it may be necessary to perform image processing such as image sharpening or haze removal. To perform such processing, it is necessary to transmit high-speed video signals to external image processing equipment and then input the processed video signals output from the image processing equipment into the imaging device. In this embodiment, an example in which the image capturing apparatus of the first embodiment is connected to a video processing device will be described.

[0054] In Patent Document 3, an E / O converter (corresponding to the image processing unit 5 in embodiment 1) is installed within the structure of the pan head device (corresponding to the base portion 4 in embodiment 1), and a connector (HD-SDI connector) is provided to connect a signal cable to the structure.

[0055] In the configuration of Patent Document 3, when the E / O converter is inserted into a structure, the signal connector is not exposed to the outside, making it difficult to directly transmit video signals to external video processing equipment. This embodiment solves this problem and makes it possible to connect video processing equipment to the video processing unit of an imaging device.

[0056] The image processing equipment 48 is equipment for performing image processing such as image sharpening and haze removal, as described above. As shown in FIG. 8 , the image processing equipment 48 has an input unit 50 to which an external video signal is input and an output unit 51 to which a video signal is output. In the first embodiment, the high-speed video signal cable 7 was connected to the high-speed signal male connector 13, but in this embodiment, the high-speed video signal cable 7 is connected to the input unit 50 of the image processing equipment 48. This connection allows the high-speed video signal from the imaging unit 1 to be directly transmitted to the image processing equipment 48. In addition, a high-speed video signal cable 49 is connected to the output unit 51 of the image processing equipment 48. The high-speed video signal cable 49 extending from the output unit 51 has a high-speed signal female connector 12 at its tip, which is connected by engaging with the high-speed signal male connector 13 of the image processing unit 5. This connection allows the high-speed video signal processed by the image processing equipment 48 to be input to the imaging device.

[0057] With the configuration of this embodiment, the high-speed video signal output from the imaging unit 1 can be transmitted to the video processing equipment 48, and the processed video signal output from the video processing equipment can be input into the imaging device. This allows the imaging device to perform video processing such as image sharpening and haze removal through the video processing equipment 48.
