Description
[Technical field]
[0001] The disclosed technology relates to a camera device. [Background technology]
[0002] Wearable camera devices that can be worn on the user's head and can capture video are known. Among such camera devices, there is a type (wired type) in which a part that captures video and a part that processes the captured video are separated via wiring. For example, Patent Document 1 discloses a camera device connected to a signal processing device via a cable. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] JP 2018-060139 A Summary of the Invention [Problem to be solved by the invention]
[0004] In recent years, cameras have become increasingly high quality. The higher the quality, the more image signals are transmitted. This is particularly noticeable in the case of video.
[0005] In the case of wired camera devices, image signals are transmitted via a cable, so as image quality improves, the number of signals transmitted via the cable also increases. In response to this, it is common to adopt a so-called serial communication method in which the image signal is converted into a serial signal on the camera side and multiple image signals are transmitted over a single signal wire.
[0006] In that case, however, it is necessary to mount an information processing device such as an IC on the camera side and convert the image signal, which leads to problems such as increased power consumption on the camera side, suppression of temperature rise inside the camera due to heat generation from the information processing device, and rising material costs, making it difficult to provide a wearable camera device, which requires compactness, at a low cost.
[0007] Therefore, it is conceivable to adopt a so-called parallel communication method, in which image signals are transmitted through separate signal wiring. With a parallel communication method, there is no need for signal conversion on the camera side, and the problems with the serial communication method described above do not occur. Another advantage is that image signals can be transmitted simultaneously in parallel, enabling high-speed transmission regardless of the number of signals.
[0008] However, in the case of a parallel communication system, the number of signal wirings increases, which makes the cable thicker and less flexible. Since a certain length is required for the cable in a wearable camera device, if the cable is thick and inflexible, it becomes an obstacle and difficult to handle. There is also a risk that the commercial value of the wearable camera device will be lost.
[0009] To address this issue, simply making the signal wiring thinner in response to an increase in the number of lines would make the wiring more susceptible to breakage and could also make the wiring more susceptible to noise from other signal wirings.
[0010] An object of the disclosed technique is to provide a wired camera device that is easy to handle and has a thin cable while maintaining appropriate strength and flexibility, even when the image quality of the wired camera device is increased. [Means for solving the problem]
[0011] The disclosed technology relates to a camera device that includes a wearable camera body capable of capturing video, and a control unit that is connected to the camera body via a single relay cable and performs image processing of the video.
[0012] The relay cable includes a pair of power supply wires for supplying power to the camera body, at least 20 signal wires for transmitting and receiving electrical signals to and from the camera body, and a tubular sheath for covering the power supply wires and the signal wires, and each of the signal wires is made of a micro coaxial cable having an outer diameter of 0.5 mm or less.
[0013] That is, according to this camera device, the relay cable is formed by bundling at least 20 signal wires made of micro coaxial cables. Even if each signal wire is microscopic, 0.5 mm or less, bundling 20 or more wires provides a suitable strength. Furthermore, bundling the signal wires allows the individual signal wires to slide against each other, providing a suitable flexibility.
[0014] Therefore, even if a parallel communication system is adopted, the long and thin relay cable can be made strong and flexible, so that even if the image quality is increased, the high quality image can be ensured and the cable can be easily handled.
[0015] The core wire of the signal wire may be formed of a twisted wire.
[0016] This makes it possible to improve strength and flexibility compared to a single wire made of one metal conductor, and makes it possible to prevent breakage of the core wire.
[0017] It is preferable that the sheath of the signal wiring is made of a material having better slipperiness than the sheath of the relay cable.
[0018] In this way, even when many signal wires are bundled together, the closely spaced signal wires can slide smoothly against each other. This ensures flexibility even for the bundle of signal wires. Meanwhile, the sheath of the relay cable can be made suitably non-slip. This makes it easier to handle the long and slender relay cable.
[0019] For example, the sheath of the signal wiring may be made of fluororesin.
[0020] This not only provides excellent slip properties, but also improves insulation properties and durability.
[0021] It is also preferable that the sheath of the relay cable is made of polyvinyl chloride.
[0022] This makes it possible to improve the flexibility of the relay cable while making the outer surface of the cable appropriately non-slip, making the relay cable easy to handle even if it is long and thin.
[0023] The camera body may have an acceleration sensor and a gyro sensor, and the signal wiring may include sensor signal wiring for receiving electrical signals from these sensors.
[0024] This allows the condition of the camera body to be properly detected and reflected in image processing, resulting in higher quality videos.
[0025] The ends of the sheaths of the signal wiring may be divided into different colors and patterns.
[0026] When soldering the extremely thin ends of many signal wires manually, the work load is extremely heavy because extremely delicate work is required. On the other hand, if the ends of the sheaths are color-coded, the number of signal wires to be processed is reduced when identifying them. This makes it easier to identify the signal wires, reduces the work load, and prevents incorrect connections. Effect of the Invention
[0027] According to a camera device to which the disclosed technology is applied, the cable can be made strong and flexible even when it is long and thin, so that even when the image quality is increased, the cable can be made easy to handle while still maintaining high image quality.

[0029] Hereinafter, exemplary embodiments will be described with reference to the drawings.

[0032] The camera body 1 is a component specialized for photography. The camera body 1 has a lens 11 for photography. The lens 11 is an ultra-wide-angle lens.

[0033] The control unit 5 is a component that executes image processing and the like for the camera device CA. The control unit 5 has a body case 50 that houses major components such as an interface, memory, and a processor. A status lamp 51 that indicates the operating state of the camera device CA is provided on the front side of the body case 50.
[0034] The control unit 5 is connected to the camera body 1 using a relay cable 7. The control unit 5 supplies power to the camera body 1 via the relay cable 7 and is connected to be able to communicate with the camera body 1. Details of the relay cable 7 will be described later.
[0035] The control unit 5 is configured to be connectable to the information terminal 100 using a connection cable 8. A USB Type-C cable is used as the connection cable 8 here. An application dedicated to the camera device CA (hereinafter referred to as a dedicated app) is installed in the information terminal 100, and the operation of the camera device CA can be controlled using the information terminal 100 by the dedicated app.
[0036] Moreover, the information terminal 100 preferably has a wireless LAN function such as Wi-Fi, or a communication function based on a mobile communication standard such as LTE, which enables the information terminal 100 to access the Internet.
[0037] An example of the information terminal 100 is a multi-function mobile phone called a smartphone. The information terminal 100 may be another mobile device such as a tablet terminal, or may be a notebook or desktop personal computer.
[0038] The control unit 5 is further configured to be connectable to a mobile battery 200 using a connection cable 8. The mobile battery 200 is used as a power source for the camera device CA. The mobile battery 200 is also used as a power source for charging the built-in battery of the information terminal 100 via the control unit 5.
[0039] 2 is a block diagram showing the electrical relationships of the main components of the camera device CA. The camera body 1 includes a camera-side power supply circuit 13, an image sensor 12, a temperature sensor 14, an acceleration sensor 15, a gyro sensor 16, a microphone 18, and a connector 20. These components are housed inside a camera case 10.
[0040] The camera-side power supply circuit 13 receives power supplied to the camera body 1 via the relay cable 7, and distributes and supplies the power. That is, the image sensor 12, the temperature sensor 14, the acceleration sensor 15, the gyro sensor 16, and the microphone 18 operate using the power supplied from the camera-side power supply circuit 13.
[0041] The imaging element 12 is provided on the rear side of the lens 11. The imaging element 12 converts the light collected by the lens 11 into an electric signal by photoelectric conversion in accordance with a control signal transmitted from the control unit 5 via the connector 20 and the relay cable 7, and generates an image signal. Examples of the imaging element 12 include a CMOS image sensor and a CCD image sensor. The image signal generated by the imaging element 12 is transmitted to the control unit 5 via the connector 20 and the relay cable 7.
[0042] The temperature sensor 14 is a sensor that detects the internal temperature of the camera body 1. Examples of the internal temperature of the camera body 1 include the internal temperature of the camera case 10 and the temperature of the image sensor 12. The temperature sensor 14 is used to perform control to ensure the operation of the image sensor 12. A temperature signal detected by the temperature sensor 14 is also transmitted to the control unit 5 via the connector 20 and the relay cable 7.
[0043] The acceleration sensor 15 is a sensor that detects three-axis acceleration. The gyro sensor 16 is a sensor that detects three-axis angular velocity. The acceleration sensor 15 and the gyro sensor 16 are used to detect the moving direction, moving distance, displacement amount, tilt, etc. of the camera body 1. Status signals detected by the acceleration sensor 15 and the gyro sensor 16 are also transmitted to the control unit 5 via the connector 20 and the relay cable 7.
[0044] The microphone 18 is a component that detects and collects sounds around the camera body 1. The microphone 18 converts sound vibrations into an electrical signal to generate a sound signal. A MEMS microphone or an electret condenser microphone (ECM) is used as the microphone 18. The sound signal detected by the microphone 18 is also transmitted to the control unit 5 via the connector 20 and the relay cable 7.
[0045] The connector 20 is a component for connecting each component of the camera body 1 to the relay cable 7. The connector 20 is composed of a receiving connector 20 (female connector 20a) installed on the camera body 1 and a plug-in connector 20 (male connector 20b) that is pre-assembled to the relay cable 7 and plugged into the male connector 20b.
[0046] In addition to the status lamp 51, the control unit 5 includes a first USB port 52, a first protection circuit 53, a body-side power supply circuit 54, a second USB port 55, a second protection circuit 56, a PD controller 63, a first memory 57, a second memory 58, a connector 20, and a control unit 60 including a processor etc. These components are housed inside the body case 50.
[0047] The first USB port 52 is a cable insertion port for connecting the mobile battery 200. As shown in Fig. 1, the mobile battery 200 is connected to the first USB port 52 via a connection cable 8. A USB Type-C port is used as the first USB port 52.
[0048] The first USB port 52 is connected to a power line via a first protection circuit 53 and a diode 61. The power line is connected to the camera-side power supply circuit 13. The first protection circuit 53 is a circuit that performs overvoltage protection also called OVP. The camera-side power supply circuit 13 converts the power supplied via the power line into a voltage suitable for each component built into the control unit 5 and supplies it, and also converts it into a voltage suitable for operating the camera body 1 and outputs it to the relay cable 7.
[0049] The second USB port 55 is a cable insertion port for connecting the information terminal 100. The information terminal 100 is connected to the second USB port 55 via a connection cable 8. The second USB port 55 is a USB Type-C port.
[0050] The second USB port 55 is connected to a power line connected to the body side power circuit 54 via a second protection circuit 56 and a switch 62. The second protection circuit 56 is a circuit that performs overvoltage protection also called OVP. The second USB port 55 is also connected to the control unit 60. The transfer modes of the second USB port 55 support USB 2.0 HS (Hi Speed) and USB 3.0 SS (Super Speed).
[0051] A signal line for charging called a CC line is mounted on the second USB port 55. The CC line of the second USB port 55 is connected to the control unit 60 via a PD controller. The PD controller controls the supply of power conforming to the USB PD standard from the control unit 60 to the information terminal 100 connected to the second USB port 55.
[0052] The status lamp 51 is composed of an LED capable of emitting light of multiple colors, such as a two-color LED or a three-color LED. The status lamp 51 is connected to the control unit 60. The lighting pattern of the status lamp 51 is switched by the control unit 60 according to the operating state of the camera device CA, such as during shooting, a sleep state (standby state), an abnormal state, etc.
[0053] The first memory 57 is a volatile memory that temporarily stores moving image data with audio. For example, a DRAM is used for the first memory 57. The second memory 58 is a non-volatile memory that records moving image data with audio. For example, a NAND type flash memory is used for the second memory 58.
[0054] The connector 20 is a component for connecting each component of the control unit 5 to the relay cable 7. Like the previous connector 20, the connector 20 is composed of a female connector 20a installed in the control unit 5 and a male connector 20b attached to the relay cable 7.
[0055] A large number of electrical signals, including image signals, temperature signals, status signals, and sound signals, transmitted from the camera body 1 are input to the control unit 60 via the relay cable 7 and a pair of connectors 20,20.
[0056] The control unit 60 functions as a signal processing unit that mainly processes image signals and sound signals. The control unit 60 temporarily stores image data of a moving image obtained from a large number of image signals and sound data obtained from one sound signal in the first memory 57. The control unit 60 then adds sound data to the image data stored in the first memory 57 to generate audio-accompanied video data. The generated audio-accompanied video data is continuously recorded in the second memory 58. The audio-accompanied video data is also sequentially transmitted to the information terminal 100 via the second USB port 55.
[0057] The audio-accompanied video data received by the information terminal 100 can be transmitted to a remote information device via the Internet using a dedicated application function. This allows a person in charge at a remote location to see and hear the situation at the work site in real time by operating the information device. In addition, if the audio-accompanied video data is uploaded to a cloud server, the situation at the work site can be checked after the fact.
[0058] <Relay cable> Fig. 3 shows the overall structure of the relay cable 7. Fig. 4 shows a schematic cross-sectional view of the relay cable 7 shown by the arrow Y-Y in Fig. 3.
[0059] The relay cable 7 is configured to be long, thin, flexible, and non-slip so as to be easy to handle. Its length L1 is, for example, in the range of 1 m to 2 m, with approximately 1.5 m being particularly preferred. Its outer diameter D1 is in the range of 2 mm to 4 mm, with approximately 2.5 mm being particularly preferred.
[0060] This camera device CA is equipped with an image sensor 12 capable of capturing images of relatively high quality, and is capable of capturing moving images. Therefore, many image signals are output from the image sensor 12, and in the case of this image sensor 12, about 20 image signals are output simultaneously in parallel.
[0061] In contrast, it is common to adopt a so-called serial communication method in which the image signal is converted to a serial signal on the camera body 1 side and multiple image signals are transmitted over a single signal wire. In that case, however, the image signal needs to be converted on the camera body 1 side, and therefore a separate information processing device must be installed on the camera body 1.
[0062] As a result, power consumption increases on the camera body 1 side due to the information processing. Accordingly, the power supplied from the control unit 5 to the camera body 1 also increases. In addition, the information processing device generates heat, causing a rise in temperature inside the camera body 1, which must be suppressed. In addition, problems such as rising material costs due to the addition of information processing devices and related components arise. For this reason, it is difficult to provide a wearable camera device, which requires compactness, at a low cost using the serial communication method.
[0063] One possible solution is to use a so-called parallel communication method, in which image signals are transmitted through separate signal wiring. With a parallel communication method, there is no need to convert signals on the camera body 1 side. Therefore, the problems with the serial communication method described above do not occur. Furthermore, it has the advantage that image signals can be transmitted simultaneously in parallel, enabling high-speed transmission regardless of the number of signals.
[0064] However, in the case of a parallel communication system, the number of signal wires increases, which makes the relay cable thicker and less flexible. If the relay cable becomes thicker and less flexible, it becomes cumbersome and difficult to handle, which may reduce the commercial value of the wearable camera device.
[0065] One possible solution to this problem is to make the signal wiring thinner so that the relay cable does not become thicker. However, simply making the signal wiring thinner makes it more susceptible to breakage and also makes it more susceptible to noise from other signal wiring.
[0066] Therefore, in this camera device CA, the signal wiring etc. are designed to eliminate such problems.
[0067] In other words, each of the signal wires 70 is made of an ultra-fine coaxial cable with an outer diameter of 0.5 mm or less, and at least 20 or more signal wires 70 are bundled together, so that the relay cable 7 is configured to have appropriate strength and flexibility even though it is long and thin.
[0068] Even if each of the signal wires 70 is extremely thin, 0.5 mm or less, bundling 20 or more wires can provide adequate strength. Bundling 25 or more wires is particularly preferable. Furthermore, bundling the signal wires 70 allows the individual signal wires 70 to slide against each other, providing adequate flexibility.
[0069] Specifically, the relay cable 7 has a number of signal wirings 70 (26 in the example shown) that transmit and receive electrical signals to and from the camera body 1, a pair of power supply wirings 71, 72 that supply power to the camera body 1, and a tubular sheath 73 that covers the power supply wirings 71 and the signal wirings 70.
[0070] The power supply wiring 71 is composed of a first power supply wiring 71 covered with an outer sheath 71a and a second power supply wiring 72 made of only a metal conductor. The second power supply wiring 72 is a drain wire that constitutes a so-called earth. As shown in Fig. 4, the core wire (metal conductor) of the first power supply wiring 71 is the same as that of the second power supply wiring 72, and is composed of a twisted wire made of seven soft copper wires W1 having an outer diameter of about 0.1 mm twisted together, and is configured so that the outer diameter D2 is about 0.25 mm.
[0071] By configuring the core wire as a twisted wire, it is possible to improve the strength and flexibility compared to a single wire consisting of one metal conductor. This makes it possible to prevent the core wire from breaking, and improves the strength and flexibility of the power supply wires 71, 72. The outer cover 71a of the first power supply wire 71 is made of a fluororesin such as PFA or ETFE, and has an outer diameter of approximately 0.4 mm.
[0072] Each of the signal wires 70 is made of the same micro-coaxial cable. Specifically, each of the signal wires 70 has a core wire 70a, an inner sheath 70b, a spiral winding 70c, and an outer sheath 70d. The core wire 70a is made of a stranded wire made of seven soft copper wires W2 having an outer diameter of about 0.02 mm, and is configured so that the outer diameter D3 is about 0.06 mm.
[0073] The inner sheath 70b is made of fluororesin like the outer cover 71a of the first power supply wiring 71, and has a thickness of about 0.4 mm and an outer diameter of about 0.15 mm. The cross winding 70c is made of a cylindrical metal conductor made of a mesh material and has an outer diameter of about 0.2 mm.
[0074] The transverse winding 70c is a so-called shield, which can prevent each signal wiring 70 from being electrically affected by other signal wirings 70. Since noise in the transmitted image signal can be prevented, high quality images can be ensured. The outer sheath 70d is made of fluororesin like the inner sheath 70b, and has an outer diameter D4 of about 0.25 mm.
[0075] Since the outer sheath 70d is made of fluororesin with excellent sliding properties, even when many signal wires 70 are bundled, the signal wires 70 that are in close contact with each other can slide smoothly. Therefore, flexibility can be ensured. By bundling many signal wires 70, even if each signal wire 70 is extremely thin, the overall strength can be ensured and breakage can be suppressed.
[0076] The sheath 73 is made of polyvinyl chloride (PVC) and has a thickness of about 0.35 mm and an outer diameter D1 of about 2.5 mm. By making the sheath 73 out of polyvinyl chloride, the relay cable 7 can be made flexible and appropriately non-slip. Therefore, the long and thin relay cable 7 can be easily handled.
[0077] Although the sliding property is somewhat poor between the signal wires 70 that are in direct contact with the inside of the sheath 73, inside the sheath 73, the signal wires 70 are in contact with each other, so that smooth sliding property is obtained.
[0078] Specifically, the outer diameters and the numbers of the signal wirings 70 and the sheath 73 are set so that the signal wirings 70 can be arranged in a circular pattern along the inner circumferential surface of the sheath 73. In particular, the signal wirings 70 and the sheath 73 are set so that the diameter of the signal wirings 70 multiplied by the number of the signal wirings 70 is at least equal to or greater than the circumferential length of a circle having a diameter obtained by subtracting the diameter of the signal wirings 70 from the inner diameter of the sheath 73 (corresponding to a circle passing through the center of the signal wirings 70 arranged along the inner circumferential surface of the sheath 73).
[0079] Furthermore, as shown in FIG. 4, it is more preferable that a plurality of signal wires 70 are provided inside the signal wires 70 arranged in a circle along the inner circumferential surface of the sheath 73 .
[0080] As a result, even if the relay cable 7 itself is long and thin, it can be easily handled while ensuring strength and flexibility.
[0081] 2, the pair of power supply wires 71, 72 are connected to the camera side power supply circuit 13 and the body side power supply circuit 54. On the other hand, each of the signal wires 70 is connected to the connector 20 (male connector 20b) as shown in FIGS.
[0082] The signal wiring 70 consists of 26 wirings including 17 signal wirings for transmitting control signals from the control unit 60 to the imaging element 12 and transmitting image signals from the imaging element 12 to the control unit 60, one signal wiring (sensor signal wiring) for transmitting a temperature signal from the temperature sensor 14 to the control unit 60, six signal wirings (sensor signal wiring) for transmitting status signals from the acceleration sensor 15 and the gyro sensor 16 to the control unit 60, and two signal wirings for transmitting sound signals from the microphone 18 to the control unit 60. Note that the number of signal wirings is one example. The type of electrical signal to be transmitted may be either digital or analog, and can be selected according to the application and specifications.
[0083] The male connector 20b has 26 tiny connection terminal portions 21 arranged in a horizontal row. The first to twenty-sixth signal wires 70 are connected by soldering to predetermined positions of these connection terminal portions 21. That is, when connecting the relay cable 7 to each male connector 20b, the end of the core wire 70a of each signal wire 70 must be soldered to the corresponding connection terminal portion 21.
[0084] Although it is possible to solder automatically using a dedicated machine, the equipment costs are high. On the other hand, manual soldering requires very delicate work, which is an extremely heavy workload. Therefore, in this camera device CA, the outer sheath 70d of the signal wiring 70 is divided into different colors and patterns to reduce the workload.
[0085] For example, the 26 connection terminal portions 21 are divided into four regions from one end to the other end: a first region 21a consisting of the first to sixth connection terminal portions 21, a second region 21b consisting of the seventh to twelfth connection terminal portions 21, a third region 21c consisting of the thirteenth to nineteenth connection terminal portions 21, and a fourth region 21d consisting of the twentieth to twenty-sixth connection terminal portions 21.
[0086] Then, the outer sheaths 70d of the signal wirings 70 corresponding to the first to fourth regions 21a to 21d are color-coded, respectively. For example, the outer sheaths 70d of the signal wirings 70 corresponding to the first region 21a are colored black, the outer sheaths 70d of the signal wirings 70 corresponding to the second region 21b are colored white, the outer sheaths 70d of the signal wirings 70 corresponding to the third region 21c are colored red, and the outer sheaths 70d of the signal wirings 70 corresponding to the fourth region 21d are colored green.
[0087] By doing so, when identifying the signal wirings 70 to be processed, the number of wirings is reduced by color coding, so that the worker performing the soldering work can easily identify the signal wirings 70 and prevent incorrect connection. When color coding is used, the number can be selected according to the total number of signal wirings 70, but five or less is preferable. If there are five or more, the individual colors become similar and identification becomes difficult.
[0088] They may be distinguished by a pattern such as stripes. For example, one or two lines may be added to the outer circumference of the outer sheath 70d. Combining this with color coding allows for even more distinctions. This further improves the ease of soldering work.
[0089] (Example) 5 shows a specific embodiment of the relay cable 7. This figure is a photograph of the end of the relay cable 7 connected to the male connector 20b. Although it cannot be seen in the figure, the bundle of signal wires 70 is color-coded into four colors. [Explanation of symbols]
