[0041] The control unit 5 is further connected to a mobile battery 200 by a wire. A third cable 9 is used to connect the control unit 5 and the mobile battery 200. The third cable 9 is a USB Type-C cable. The mobile battery 200 is a power source for supplying power from the control unit 5 to the camera body 1. The mobile battery 200 can also be used as a power source for charging the built-in battery of the mobile terminal 100 via the control unit 5.

These components are housed inside a first housing 10. The first housing 10 is a portable device.

[0043] The first power supply circuit 13 receives power supplied to the camera body 1 via the first cable 7, and converts the power into a voltage suitable for each component built into the camera body 1 and supplies it to the components. The image sensor 11b, the temperature sensor 14, the acceleration sensor 15, the gyro sensor 16, and the microphone 18 function by receiving power supplied from the first power supply circuit 13.

[0044] The imaging unit 11 is provided in the first housing 10 and captures an image of the periphery of the first housing 10. The imaging unit 11 is connected to the control unit 60 via wired communication. The imaging unit 11 includes a lens 11a and an imaging element 11b. The imaging element 11b is provided on the rear side of the lens 11a. The imaging element 11b converts light collected by the lens 11a into an electrical signal by photoelectric conversion to generate an image signal. Examples of the imaging element 11b include a CMOS image sensor and a CCD image sensor. The image signal generated by the imaging element 11b is output to the first connector 19 and transmitted to the control unit 5 via the first cable 7.

[0045] 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 temperature of the internal space of the first housing 10 and the temperature of the image sensor 11b. The temperature sensor 14 is used to perform control to ensure the operation of the image sensor 11b. A detection signal indicating the temperature detected by the temperature sensor 14 is output to the first connector 19.

[0046] The acceleration sensor 15 is a sensor that detects acceleration on three axes. The acceleration sensor 15 detects the direction of gravitational acceleration acting on the camera body 1. The gyro sensor 16 is a sensor that detects angular velocity on three axes. The gyro sensor 16 detects angular velocity when the orientation of the camera body 1 changes. A detection signal indicating the acceleration detected by the acceleration sensor 15 and a detection signal indicating the angular velocity detected by the gyro sensor 16 are output to a first connector 19.

[0047] 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. A sound signal indicating the sound detected by the microphone 18 is output to a first connector 19.

[0048] The first connector 19 is a component to which the first cable 7 is connected. A coaxial thin-wire connector is used for the first connector 19. The first connector 19 transmits the image signal output from the imaging element 11b, the detection signals output from the temperature sensor 14, the acceleration sensor 15, and the gyro sensor 16, and the sound signal output from the microphone 18 to the control unit 5 via the first cable 7.

[0049] The reception unit 20 receives instructions for controlling the camera device CA. In this embodiment, the reception unit 20 is, for example, a capacitive or pressure-sensitive touch sensor, and detects a touch operation (operation by contact) on the surface of the first housing 10. When the reception unit 20, which is a touch sensor, detects a touch operation on the surface of the first housing 10, it outputs a signal corresponding to the detected touch operation to the control unit 60 described later.

[0050] The reception unit 20 receives, by a touch operation on the surface of the first housing 10, an instruction to cause the imaging unit 11 to start an imaging operation, an instruction to cause the imaging unit 11 to end an imaging operation, an instruction to switch the operation mode of the camera device CA between on and off, and the like. An example of the operation mode of the camera device CA is a privacy protection mode. When the privacy protection mode is on, the imaging operation of the imaging unit 11 can be started and ended by a touch operation by the reception unit 20. When the privacy protection mode is off, the reception unit 20 does not receive a touch operation, and the imaging operation of the imaging unit 11 cannot be started and ended by a touch operation by the reception unit 20.

[0051] The types of touch operations include, for example, a single tap operation, a double tap operation, a long press operation, etc. For example, the type of instruction accepted by the accepting unit 20 may be set according to the type of touch operation, such that a single tap operation is used to instruct the imaging unit 11 to end or start an imaging operation, and a double tap operation is used to instruct the camera device CA to switch the operation mode.

[0052] The notification unit 21 notifies the state of the camera device CA. The notification unit 21 includes a light source such as an LED. The LED is configured by an LED capable of emitting light of multiple colors such as a two-color LED or a three-color LED. The light source, which is the notification unit 21, is provided on the surface of the first housing 10. The notification unit 21 notifies the state of the camera device CA by changing the light emission color of the light source, changing the time interval for blinking the light source, changing the continuous lighting time of the light source, etc. according to the state of the camera device CA. The state of the camera device CA may be, for example, that the imaging unit 11 is performing an imaging operation, that the imaging unit 11 has stopped an imaging operation, or the current operation mode or state of the camera device CA (whether the privacy protection mode is on or off), etc.

[0053] In addition to the status lamp 51, the control unit 5 includes a first USB port 52, a first protection circuit 53, a second 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 second connector 59, and a control unit 60. These components are housed inside the second housing 50.

[0054] The first USB port 52 is a cable insertion port for connecting the mobile battery 200. The third cable 9 is inserted into the first USB port 52, and the mobile battery 200 is connected via the third cable 9. A USB Type-C port is used as the first USB port 52.

[0055] The first USB port 52 is connected to a power line (VBUS) via a first protection circuit 53 and a diode 61. The power line is connected to a second power circuit 54. The first protection circuit 53 is a circuit that performs overvoltage protection also known as OVP. The second power circuit 54 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 first cable 7.

[0056] The second USB port 55 is a cable insertion port for connecting the mobile terminal 100. A second cable 8 is inserted into the second USB port 55, and the mobile terminal 100 is connected via the second cable 8. A USB Type-C port is used as the second USB port 55.

[0057] The second USB port 55 is connected to a power line connected to the second 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).

[0058] 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 63. The PD controller 63 controls the supply of power conforming to the USB PD standard from the control unit 60 to the mobile terminal 100 connected to the second USB port 55.

[0059] 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.

[0060] 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.

[0061] The second connector 59 is a component to which the first cable 7 is connected. A coaxial thin-wire connector is used for the second connector 59. The second connector 59 receives the image signal, each detection signal, and sound signal transmitted from the camera body 1 via the first cable 7, and outputs them to the control unit 60.

[0062] The control unit 60 controls the camera device CA. Controlling the camera device CA means controlling the devices (imaging unit 11, notification unit 21, etc.) included in the camera device CA. The control unit 60 controls the mobile terminal 100 by transmitting a control signal to the mobile terminal 100 via the second cable 8.

[0063] The control unit 60 functions as a signal processing unit that processes image signals and sound signals. The control unit 60 temporarily stores image data indicated by the image signal and sound data indicated by the sound signal input via the second connector 59 in the first memory 57. The control unit 60 then adds the sound data to the image data stored in the first memory 57 to generate audio-accompanied video data, which is continuously recorded in the second memory 58 and sequentially transmitted to the mobile terminal 100 via the second USB port 55.

[0064] Before storing image data in first memory 57, or when generating audio-accompanying video data, control unit 60 performs distortion correction on the image data based on internal parameters of camera body 1 to convert the image into an image free of distortion caused by lens aberration, etc. Control unit 60 further performs a cut-out process to cut out a predetermined range from the distortion-corrected image data.

[0065] In this cropping process, the inclination of the cropped range of the image data and the cropping position are corrected based on the rotational movement and translational movement around the optical axis of the lens 11a of the camera body 1. This correction is also called electronic gimbaling, and cancels the displacement of the captured image caused by dynamic changes in the attitude and shaking of the camera body 1. The rotational movement and translational movement of the camera body 1 are obtained from the detection signals from the acceleration sensor 15 and the gyro sensor 16.

[0066] The control unit 60 also switches the image output mode between a first mode and a second mode. The first mode is a mode in which the control unit 60 outputs image data having a narrower angle of view than the second mode. The image data output in the first mode corresponds to shooting data having an angle of view of, for example, about 60° to 90°. The second mode is a mode in which the control unit 60 outputs image data of the entire shooting range of the camera body 1. The image data output in the second mode corresponds to shooting data having an angle of view of, for example, about 120° to 180°.

[0067] The above-mentioned cropping process does not have to be performed when the image output mode is the second mode. In the second mode, tilt correction and shake correction by the electronic gimbal are not performed. In addition, when the camera device CA is used as a wearable camera by attaching the camera body 1 to the temple TE of the glasses GL, it is assumed that the image output mode is basically set to the first mode in order to enable tilt correction and shake correction by the electronic gimbal.

[0068] The control unit 60 may have a function of recognizing sound data. In this case, the control unit 60 may be configured to recognize a voice uttered by the user DU, and switch the image output mode when the recognized voice is a predetermined word. In addition, the user DU may be able to switch the image output mode by setting the output mode using a dedicated application.

[0069] The control unit 60 also controls thermal shutdown. The imaging element 11b has a predetermined guaranteed operating temperature. Therefore, the control unit 60 performs processing to interrupt image capture when the temperature indicated by the detection signal from the temperature sensor 14 exceeds a predetermined temperature, so that the imaging element 11b does not exceed the guaranteed operating temperature. The control unit 60 is realized using an ASIC or the like.

[0070] In the camera device CA, when the mobile battery 200 is connected to the control unit 5, the camera body 1 and the control unit 5 are started up. Then, shooting is automatically performed by the imaging section 11 of the camera body 1, and audio-accompanied video data according to the image output mode of the control section 60 is transmitted to the mobile terminal 100. The audio-accompanied video data received by the mobile terminal 100 is transferred to a remote external device 300 via the Internet by a function of a dedicated app. The external device 300 is connected to the mobile terminal 100 so as to be able to communicate wirelessly. The external device 300 is a PC (Personal Computer) that communicates bidirectionally with the mobile terminal 100 wirelessly.

[0071] The person in charge at a remote location can view the situation at the work site in real time by accessing the external device 300 to which the audio-accompanied video data has been transferred. Also, if the audio-accompanied video data is uploaded to a cloud server when it is transferred from the mobile terminal 100, the person in charge at the remote location and the user DU can check the audio-accompanied video data after the fact.

[0072] - Camera equipment processing - As shown in FIG. 5, in step S1, the mobile battery 200 is connected to the control unit 5 of the camera device CA, and the camera device CA is started up.

[0073] In step S2, the control unit 60 causes the imaging unit 11 to start an imaging operation.

[0074] In step S3, control unit 60 determines whether or not the input unit of mobile terminal 100 has received an end instruction to end the imaging operation of imaging unit 11. If the input unit of mobile terminal 100 has received an end instruction (Yes in step S3), the process proceeds to step S4. If the input unit of mobile terminal 100 has not received an end instruction (No in step S3), the process proceeds to step S5.

[0075] In step S4, the control unit 60 causes the imaging unit 11 to end the imaging operation.

[0076] In step S5, the control unit 60 determines whether the privacy protection mode of the camera device CA is on. If the privacy protection mode is on (Yes in step S5), the process proceeds to step S6. If the privacy protection mode is off (No in step S5), the process proceeds to step S7.

[0077] In step S6, the control unit 60 determines whether the reception unit 20 of the camera device CA has received an end instruction to end the imaging operation of the imaging unit 11. If the reception unit 20 has received the end instruction (Yes in step S6), the process proceeds to step S4. If the reception unit 20 has not received the end instruction (No in step S6), the process proceeds to step S7.

[0078] In step S7, if the mobile battery 200 is removed from the control unit 5 of the camera device CA and the camera device CA is shut down (Yes in step S7), the processing ends, and if the mobile battery 200 remains connected to the control unit 5 (No in step S7), the processing proceeds to step S3.

[0079] -Variations- In this embodiment, the first housing 10 of the camera device CA is attached to glasses GL. However, the present invention is not limited to this. The first housing 10 may be attached to a person's head or an object attached to a person's head. For example, the first housing 10 may be attached to a helmet, a hat, or the like. The first housing 10 may also be attached to a strap attached to a person's head, such as a head strap. Thus, the first housing 10 is attached to a person's head or an object attached to a person's head, and the second housing 50 and the mobile terminal 100 are carried by the person.

[0080] The reception unit 20 in this embodiment is a touch sensor. However, the present invention is not limited to this.

The notification unit 21 may also be a display device such as a liquid crystal display. In this case, the notification unit 21 notifies the state of the camera device CA by an image displayed on the display device. In addition, a device other than the camera device CA such as the mobile terminal 100 may function as the notification unit 21. In this case, for example, the control unit 60 controls a device other than the camera device CA such as the mobile terminal 100 so that the device notifies the state of the camera device CA.

[0083] The reception unit 20 may be configured not to receive any touch operation other than a predetermined touch operation when the imaging operation of the imaging unit 11 is stopped. In this case, when the reception unit 20 receives the predetermined touch operation, the control unit 60 controls the imaging unit 11 so that the imaging operation of the imaging unit 11 is resumed. The predetermined touch operation is, for example, a double tap operation.

[0084] When the control unit 60 of the camera device CA executes the instruction accepted by the accepting unit 20, the control unit 60 may control the mobile terminal 100 so that the mobile terminal 100 notifies the user that the instruction has been executed. The mobile terminal 100 notifies the user that the instruction has been executed by, for example, a sound, a vibration, a screen display, an indicator, or the like.

[0085] The first housing 10 may be provided with a light sensor that detects the brightness (illuminance or luminance) of the surroundings of the first housing 10. When the imaging unit 11 is performing an imaging operation, if the detection result of the light sensor is darker than a predetermined brightness (lower than a predetermined illuminance or a predetermined luminance), the control unit 60 may control the imaging unit 11 so that the imaging unit 11 stops the imaging operation, and if the detection result of the light sensor is brighter than the predetermined brightness (not less than a predetermined illuminance or not less than a predetermined luminance), the imaging unit 11 continues the imaging operation.

[0086] In addition, when the imaging operation by the imaging unit 11 is being performed, if the detection result of the light / dark sensor becomes darker than a predetermined brightness and the period when it remains darker than the predetermined brightness continues for a predetermined period of time (if the detection result of the light / dark sensor that is lower than the predetermined illuminance or predetermined luminance continues for a predetermined period of time), the imaging unit 11 may stop the imaging operation, and in other cases (if the detection result of the light / dark sensor that is lower than the predetermined illuminance or predetermined luminance does not occur, or if such detection result occurs but does not continue for the predetermined period of time), the control unit 60 may control the imaging unit 11 so that the imaging unit 11 continues the imaging operation.

[0087] When the imaging unit 11 is performing an imaging operation and the image captured by the imaging unit 11 becomes a predetermined image (e.g., an image of a toilet bowl), the control unit 60 may control the imaging unit 11 so that the imaging unit 11 stops the imaging operation.

[0088] The instructions for controlling the camera device CA received by the receiving unit 20 may include not only an instruction to stop the imaging operation by the imaging unit 11, but also an instruction to convert the image captured by the imaging unit 11 into a mosaic image, an instruction to stop the imaging operation by the imaging unit 11 but to continue the operation of generating an audio signal of the sound around the camera body 1 by the microphone 18, etc.
