[0027] See also Figure 1 as well as Figure 2 As shown, the present application proposes a lens 100. The lens 100 includes a lens body 10 and a lens interface 20; the lens body 10 is provided with a main control board 30 and a wireless communication module connected to the main control board 30 (the wireless communication module is installed on the main control board, not marked), and the wireless communication module is used to communicate with the electronic device; the lens interface 20 is located on the lens body 10, and the lens interface 20 is used to connect to the camera body.

[0028] In the technical solution of the present application, it is worth noting that the camera body has a built-in power supply. When the lens body 10 is connected to the camera body through the lens interface 20, electrical connection can be achieved through the contact between the lens body 10 and the camera body, so that power is supplied to the lens body 10 through the camera body; and the data stream can be wirelessly transmitted from other electronic devices to the lens body 10 through the wireless communication module, thereby realizing separate control of power supply and data transmission of the lens 100.

[0029] The lens mount 20 includes one of an E-mount, a DL-mount, a Z-mount, an RF-mount, a PL-mount, an L-mount, an EF-mount, an F-mount, an A-mount, a K-mount, and an X-mount. These mounts are common interfaces for the lens 100 to achieve a stable connection with the camera body, and the user can select one based on actual conditions.

[0030] The lens body 10 includes a lens barrel with a lens installed, a frame 11 for structural support, and an appearance part 12 arranged around the frame 11. In a specific configuration, the main control board 30 and the wireless communication module are installed on the outside of the frame 11 and covered by the appearance part 12 to form installation and protection.

[0031] The camera and the lens 100 are a conventional combination kit, and the camera has its own power supply. Generally, in outdoor travel scenes, the user will carry the camera and the lens 100 at the same time, so the lens 100 can be powered at any time after assembly.

[0032] After power is supplied, various electronic devices in the lens body 10 start to work. The wireless communication module can then establish a communication connection with an external electronic device, and the user can transmit data to the lens body 10 based on the external electronic device to upgrade or control the lens body 10. Exemplary includes:

[0033] 1) Implement OTA upgrades. Also known as Over-the-Air Technology, it is a wireless download upgrade method. It refers to upgrading device firmware or software through wireless communication. Users can remotely push new firmware versions to devices to fix vulnerabilities, add new features, or improve device performance. The advantages of OTA upgrades include the ability to upgrade software for devices distributed in various locations without having to have maintenance personnel travel around, as well as the ability to fix system vulnerabilities and implement system upgrades.

[0034] 2) Implement parameter control function. After the lens body 10 establishes a communication connection with the electronic device, the user can transmit control parameters from the electronic device to the lens body 10 through the wireless module. These parameters can be operating parameters of the device, control instructions, etc., such as adjustment instructions for the focal length and aperture size of the lens 100. After receiving the control instruction, the lens body 10 performs corresponding processing.

[0035] In some embodiments, the wireless communication module includes a Bluetooth transmission module, a StarFlash transmission module, an NFC transmission module, etc. The above examples all have good wireless transmission performance and can be selected according to needs in actual applications.

[0036] In some embodiments, the electronic device includes one of a smart phone, a tablet, a laptop computer, and a camera. These electronic devices are also equipped with a wireless communication module, which can establish a communication connection with the lens body 10. In a conventional selection, these electronic devices are provided with an APP software corresponding to the lens 100, the APP software matches the current lens 100, the current lens 100 and the electronic device communicate with each other, and the user can query the parameter information of the current lens 100 in the APP software and adjust the current parameter information, which is highly practical, convenient and fast.

[0037] For example, in one application, a camera with a lens 100 can be fixed by a tripod during shooting, wherein the tripod can avoid vibration, and the fixing effect of the camera and the lens 100 is better than handheld shooting. At this time, based on the wireless communication module, the user can adjust the lens parameters through an external electronic device without touching the lens 100, and the contactless adjustment can maintain the tripod fixing effect.

[0038] For example, in another application, during filming, the person holding the camera and the person following the focus can be separated, that is, the person holding the camera is responsible for aiming the camera at the shooting scene, while the person following the focus can wirelessly control the lens 100 to achieve remote following the focus. Division of labor and cooperation can improve filming efficiency.

[0039] See also Figure 3 As shown, in some embodiments, a power supply interface 121 is provided on the lens body 10, and the power supply interface 121 is used to connect to an external power supply through a data line, and the lens body 10 is powered by the external power supply.

[0040] In this embodiment, another power supply method for the lens body 10 is proposed, that is, a power supply interface 121 is provided on the lens body 10, and the lens body 10 is directly connected to an external power source through the power supply interface 121. The external power source can be a portable charging power source or a household power source. Furthermore, the lens 100 can be powered through other paths without being connected to the camera body. After power supply, wireless communication connection with electronic equipment can be further performed to realize data stream transmission of the lens 100, so that the lens 100 can be applied in a wider range of scenarios.

[0041] The power supply interface 121 may be one of a USB interface, a Type-C interface and a Lightning interface.

[0042] In some embodiments, the power supply interface 121 also has a data import function. The power supply interface 121 is used to connect to an external smart device via a data cable and provide data import when power is supplied.

[0043] In this embodiment, the power supply and data import of the lens body 10 are centralized on one interface, and data import can be provided while power is supplied, so as to realize another control method of the lens body 10. Exemplarily, the power supply interface 121 is connected to a smart phone via a data cable, and at this time, the smart phone can supply power to the lens body 10, and at the same time, the user can operate on the smart phone to send the data stream to the lens body 10 via the data cable.

[0044] Generally speaking, data transmission via data line connection is more stable than wireless transmission.

[0045] See also Figure 3 As shown, in some embodiments, a data interface 122 is further provided on the lens body 10, and the data interface 122 is used to connect to an electronic device via a data cable to provide data import via the data cable.

[0046] In this embodiment, the control mode is based on the power supply of the camera body and the data transmission is performed through the data line. Among them, the data interface 122 is only used to transmit the data stream sent by the electronic device.

[0047] In some special cases, such as when the lens body 10 is connected to the camera body and connected to an external electronic device via a data cable, the system defaults to the external electronic device powering the lens body 10 to take precedence over the camera body powering the lens body 10 to ensure that the camera body has sufficient power. In order to ensure the power supply to the lens body 10, the power supply can be manually switched to the camera body when the power of the external electronic device is insufficient.

[0048] In some embodiments, a power indicator light 123 is disposed on the lens body 10 , and the power indicator light 123 is configured to light up when the lens body 10 is powered on.

[0049] In this embodiment, the power indicator light 123 is provided to determine whether the lens body 10 is currently powered, thereby determining whether a communication connection with the electronic device can be established based on the wireless communication module, so as to facilitate the user to eliminate the power supply problem of the lens body 10 when the communication connection cannot be established.

[0050] See also Figure 2 In some embodiments, the lens 100 is further provided with a display unit 40, the display unit 40 is electrically connected to the main control board 30, and the display unit 40 is used to receive and display the lens parameters sent by the main control board 30.

[0051] In this embodiment, the display unit 40 may be a display screen provided on the exterior member 12, and may be used to display lens parameters after the lens 100 is powered, and these lens parameters include data such as focal length parameters, aperture size, and front and rear depth of field of the lens 100. After the display unit 40 is provided, it is convenient for the user to understand the current performance indicators of the lens 100, and help the user to achieve a better shooting effect.

[0052] In summary, the lens 100 provided in this application can realize wireless connection with electronic devices through the wireless communication module after the camera body is powered, so that the user can control the lens 100 through the electronic device, which is practical and convenient and has a wide range of application scenarios. Other power supply methods and data transmission methods are proposed in this application to further improve the applicability of the lens 100.

[0053] The present application also provides an image pickup device, which includes a camera body and the lens 100 as described above, and the camera body and the lens 100 are detachably connected.

[0054] In this embodiment, the image pickup device adopts all technical solutions of all embodiments of the lens 100, and therefore has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0055] The above description is only a partial or preferred embodiment of the present application. Neither the text nor the drawings can limit the scope of protection of the present application.
