[0061] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0062] To address the problems existing in related technologies, this disclosure provides a gimbal camera and camera accessories. The gimbal camera includes a gimbal and a shooting device mounted on the gimbal. The shooting device includes a housing, a lens portion, a first connecting portion, and a second connecting portion disposed on the housing. The first connecting portion is used for mechanical coupling with a detachable camera accessory. When the detachable camera accessory is mechanically coupled to the first connecting portion, the gimbal camera forms an electrical connection with the camera accessory through the second connecting portion. In this disclosure, when the detachable camera accessory is mechanically coupled to the gimbal camera, the camera accessory can also form an electrical connection with the gimbal camera. The gimbal camera can determine the type of camera accessory based on the electrical connection and adaptively adjust the parameters of the lens portion according to the type of camera accessory, thereby improving image quality.

[0063] According to an exemplary embodiment of this disclosure, such as Figure 1 As shown, this embodiment provides a gimbal camera, which is a device assembly including a gimbal 300 and a shooting device 100 mounted on the gimbal 300. The gimbal 300 includes at least two connected axes, which can rotate around a rotation axis to provide stabilization and other functions for the shooting device 100. Gimbal cameras include, but are not limited to, handheld gimbal cameras (see...). Figure 1 ) and onboard gimbal cameras (drones, unmanned vehicles, etc.).

[0064] like Figure 1As shown, the shooting device 100 includes a housing 10 and a lens 20. The lens 20 is disposed within a mounting space defined inside the housing, and the exterior of the housing 10 is used for connection with a gimbal. In this embodiment, the shape of the housing 10 and the type of lens 20 are not excessively limited.

[0065] like Figure 1 and Figure 2 As shown, the shooting device 100 also includes a first connecting part (not shown in the figure). The first connecting part is disposed on the housing 10. The shooting device 100 is detachably connected to the camera accessory 200 through the first connecting part. When the camera accessory 200 is mounted on the shooting device 100, the first connecting part is used to achieve mechanical coupling between the shooting device 100 and the camera accessory 200, so that the camera accessory 200 and the shooting device 100 form a reliable mechanical connection. The detachable connection method includes magnetic connection, snap-fit ​​connection, fastener connection, etc.

[0066] like Figure 1 and Figure 2 As shown, the shooting device 100 also includes a second connecting part 30, which is disposed on the housing 10. When the camera accessory 200 forms a mechanical coupling with the shooting device 100 through the first connecting part, a specific structure on the camera accessory 200 (such as the fourth connecting part 50, which is described in the camera section below) can form an electrical connection with the second connecting part 30, so that an electrical connection is formed between the gimbal camera and the camera accessory 200.

[0067] It should be noted that by establishing an electrical connection, the gimbal camera can, for example, determine the type of camera accessory 200 it is equipped with. Furthermore, the gimbal camera can adaptively adjust the parameters of the lens section 20 according to the type of camera accessory 200, so that the lens section 20 and the camera accessory 200 can work together better, thereby improving the shooting quality. For example, if the camera accessory 200 is a fill light, after installing a fill light on the shooting device 100, the shooting device 100 can appropriately reduce the aperture to avoid overexposure due to excessive light intake.

[0068] When the camera accessory 200 is an adjustable electronic accessory, establishing an electrical connection also allows the gimbal camera to adjust the optical parameters of the camera accessory 200 to meet the shooting needs of various scenarios. For example, the camera accessory 200 is an electronic neutral density (ND) filter, and the user can adjust the transmittance of the ND filter through the gimbal camera's controller to filter out different ambient light in different scenarios. The camera accessory 200 also includes softboxes, wide-angle filters, etc., which will not be described in detail here.

[0069] In this embodiment, when the detachable camera accessory is mechanically coupled to the gimbal camera, the camera accessory can also form an electrical connection with the gimbal camera. The gimbal camera can determine the type of camera accessory based on the electrical connection and adaptively adjust the parameters of the lens according to the type of camera accessory, thereby improving the image quality.

[0070] In one exemplary embodiment, such as Figure 1 As shown, this embodiment provides a gimbal camera, which includes a gimbal and a shooting device 100 mounted on the gimbal. The shooting device 100 includes a housing 10, a lens portion 20, a first connecting portion (not shown in the figure), and a second connecting portion 30 disposed on the housing 10. The first connecting portion is used for mechanical coupling with a detachable camera accessory 200. When the detachable camera accessory 200 is mechanically coupled with the first connecting portion, the gimbal camera forms an electrical connection with the camera accessory 200 through the second connecting portion 30.

[0071] Among them, such as Figure 2 As shown, the second connection portion 30 of the shooting device 100 includes a first power supply terminal 32, a first ground terminal 33, and a first signal terminal 31. When the camera accessory 200 is mechanically coupled to the shooting device 100, the first power supply terminal 32 and the first ground terminal 33 enable the gimbal camera and the camera accessory 200 to form a power-on circuit. The first signal terminal 31 is connected to the power-on circuit, and the gimbal camera can determine the type of camera accessory 200 through the electrical parameters at the first signal terminal 31.

[0072] In one example, the type of camera accessory 200 can be determined based on the detected voltage level. For example, see [link to relevant documentation]. Figures 2 to 4 ,or Figures 5 to 7 The first signal terminal 31 is connected to the first connection point 63 of the power-on circuit. A first resistor 61 and a second resistor 62 are provided on the power-on circuit. The first resistor 61 is located between the first power supply terminal 32 and the first connection point 63, and the second resistor 62 is located between the first connection point 63 and the first ground terminal 33. Based on the fact that the voltage across a resistor in a series circuit is proportional to its resistance value, the resistance ratio of the first resistor 61 and the second resistor 62 in different types of camera accessories 200 can be set to be different, thus resulting in different voltage values ​​for the first resistor 61 and the second resistor 62. For example, a gimbal camera can detect the voltage across the first power supply terminal 32 and the first signal terminal 31 (i.e., the first resistor 61), or it can detect the voltage across the first ground terminal 33 and the first signal terminal 31 (i.e., the second resistor 62), thereby determining the type of camera accessory 200. In an optional embodiment, the value of the first resistor 61 in each type of camera accessory 200 can be set to be the same, and the resistance value of the second resistor 62 can be adaptively set.

[0073] In another example (not shown in the attached diagram), the type of camera accessory can be determined based on the magnitude of the current detected at the first signal terminal. For example, the camera accessory includes a third resistor, a fourth resistor, and a fifth resistor. The fourth and fifth resistors are connected in parallel, and the parallel fourth and fifth resistors are connected in series with the third resistor. The fourth resistor is positioned between the third resistor and the first ground terminal, and the fifth resistor is positioned between the third resistor and the first signal terminal. Since a larger resistance value results in a smaller current when the voltage is the same (the voltage across the fourth and fifth resistors is the same), the resistance values ​​of the fourth and fifth resistors in different types of camera accessories can be set differently. The gimbal camera can determine the type of camera accessory by detecting the magnitude of the current at the first signal terminal.

[0074] In some embodiments, such as Figures 2 to 4 The second connection part 30 also includes a second signal terminal 34, through which the gimbal camera can output control signals to adjust the optical parameters of the camera accessory 200.

[0075] In other embodiments, such as Figures 5 to 7 As shown, the second connection portion 30 does not have a second signal terminal 34. Instead, the first signal terminal 31 is configured to output control signals or detection signals in different cycles. For example, during cycle T1, the gimbal camera can acquire voltage signals to characterize the type of camera accessory 200 through the first signal terminal 31. Cycle T1 may be within a preset duration during which a power-on circuit is formed between the first power supply terminal 32 and the first ground terminal 33. During cycle T2, the gimbal camera can output control signals to the camera accessory 200 through the first signal terminal to adjust the optical parameters of the camera accessory 200. Cycle T2 may be within a time range after the power-on circuit between the first power supply terminal 32 and the first ground terminal 33 has exceeded the preset duration. In this embodiment, by using time-division multiplexing for the first signal terminal 31, the number of pins can be reduced, the structure simplified, and resource utilization improved.

[0076] In one exemplary embodiment, such as Figure 1 As shown, this embodiment provides a gimbal camera, which includes a gimbal and a shooting device 100 mounted on the gimbal. The shooting device 100 includes a housing 10, a lens portion 20, a first connecting portion, and a second connecting portion 30 disposed on the housing 10. The first connecting portion is used for mechanical coupling with a detachable camera accessory 200. When the detachable camera accessory 200 is mechanically coupled with the first connecting portion, the gimbal camera forms an electrical connection with the camera accessory 200 through the second connecting portion 30.

[0077] The gimbal camera provided in this embodiment may include various structures and components of the gimbal camera provided in any of the above embodiments.

[0078] The second connection portion 30 includes one of a spring probe and a probe connector, the other of which is disposed on the camera accessory 200. The pins on the spring probe or the pins on the probe connector constitute the first power supply terminal 32, the first ground terminal 33, and the first signal terminal 31 of the second connection portion 30.

[0079] In some embodiments, the shooting device 100 is connected to the camera accessory 200 by a first connecting part. For example, the first connecting part is a slot on the housing 10 of the shooting device 100, and the camera accessory 200 is provided with an elastic buckle. The elastic buckle can be engaged in the slot based on the deformation recovery force to realize the snap connection between the shooting device 100 and the camera accessory 200.

[0080] In other embodiments, the shooting device 100 is magnetically connected to the camera accessory 200 via a first connecting portion. For example, the first connecting portion of the shooting device 100 is made of a ferromagnetic material, and a magnet is provided on the camera accessory 200. A magnetic attraction force is formed between the magnet and the first connecting portion to achieve a magnetic connection between the shooting device 100 and the camera accessory 200.

[0081] In some other embodiments, the shooting device 100 and the camera accessory 200 are connected by both a snap-fit ​​connection and a magnetic connection through the first connecting part, so as to enhance the connection reliability between the shooting device 100 and the camera accessory 200.

[0082] According to an exemplary embodiment of this disclosure, such as Figure 1 As shown, this embodiment provides a camera accessory 200, which can be detached from the gimbal camera to improve shooting quality when the gimbal camera cannot meet the shooting requirements through its own structural components. After shooting, the camera accessory 200 can be removed and stored.

[0083] like Figures 2 to 4 As shown, the camera accessory 200 includes an accessory body 40, a third connecting part (not shown in the figure), and a fourth connecting part 50. The third connecting part and the fourth connecting part 50 are disposed on the accessory body 40. The third connecting part is used for mechanical coupling with the first connecting part of the shooting device 100 of the gimbal camera. When the camera accessory 200 is mechanically coupled to the shooting device 100, the camera accessory 200 can form an electrical connection with the gimbal camera through the fourth connecting part 50. The gimbal camera can identify the type of camera accessory 200 that is electrically connected to it, or adjust the optical parameters of the camera accessory 200 to improve the user experience when using the camera accessory 200.

[0084] In this embodiment of the disclosure, when the detachable camera accessory is mechanically coupled to the gimbal camera, the camera accessory can also form an electrical connection with the gimbal camera. The gimbal camera can determine the type of camera accessory based on the electrical connection and adaptively adjust the parameters of the lens according to the type of camera accessory, thereby improving the image quality.

[0085] In one exemplary embodiment, such as Figure 1 As shown, this embodiment provides a camera accessory 200, which is detachably disposed on the outer surface of the housing 10 of the shooting device 100 of the gimbal camera. The camera accessory 200 includes an accessory body 40, a third connecting part and a fourth connecting part 50. The third connecting part is used for mechanical coupling with the first connecting part of the shooting device 100 of the gimbal camera. When the camera accessory 200 is mechanically coupled with the shooting device 100, the camera accessory 200 forms an electrical connection with the gimbal camera through the fourth connecting part 50.

[0086] Among them, such as Figure 3 and Figure 4 As shown, the camera accessory 200 has a detection module 60 inside its accessory body 40, and the fourth connection part 50 includes a second power supply terminal 52, a second ground terminal 53, and a third signal terminal 51. When the camera accessory 200 is mechanically coupled to the shooting device 100, the second power supply terminal 52 can be electrically connected to the first power supply terminal 32 on the shooting device 100, and the second ground terminal 53 can be electrically connected to the first ground terminal 33 on the shooting device 100 to form a power circuit.

[0087] See Figure 3 The detection module 60 contains multiple resistors, and the resistance ratios of these resistors differ for different types of camera accessories 200. The third signal terminal 51 can be electrically connected to the first signal terminal 31 on the shooting device 100. The gimbal camera can be electrically connected to the detection module 60 via the first signal terminal 31 and the second signal terminal 34, and the type of camera accessory 200 can be determined by the detected voltage or current. In some embodiments, such as Figure 3 As shown, the detection module 60 of the camera accessory 200 includes a first resistor 61 and a second resistor 62. The first resistor 61 and the second resistor 62 are connected in series in the power supply circuit between the second power supply terminal 52 and the second ground terminal 53. The first resistor 61 and the second resistor 62 have a first connection point 63. The second signal terminal 34 is connected to the power supply circuit through the first connection point 63. The principle of determining the type of camera accessory 200 has been explained in the aforementioned embodiments of the gimbal camera side of this disclosure, and will not be repeated here.

[0088] In some embodiments, such as Figures 2 to 4As shown, the fourth connection portion 50 of some types of camera accessories 200 also includes a fourth signal terminal 54. When the camera accessory 200 is mechanically coupled to the shooting device 100, the fourth signal terminal 54 can be electrically connected to the second signal terminal 34 on the shooting device 100. The gimbal camera can send control signals to the camera accessory 200 through the second and fourth signal terminals 54 to adjust the optical parameters of the camera accessory 200. The implementation principle has been explained in the aforementioned embodiments on the gimbal camera side of this disclosure, and will not be repeated here. The camera accessory 200 involved in this embodiment is a first type accessory 200a, which includes, but is not limited to, a fill light module and an electronic neutral density filter.

[0089] In other embodiments, such as Figures 5 to 7 As shown, the fourth connection portion 50 of the camera accessory 200 does not have a fourth signal terminal 54, and the second connection portion 30 of the shooting device 100 does not have a second signal terminal 34. Instead, the first signal terminal 31 and the third signal terminal 51 are time-division multiplexed. The principle of time-division multiplexing has been explained in the aforementioned gimbal camera section of this disclosure, and will not be repeated here.

[0090] In one exemplary embodiment, such as Figure 1 As shown, this embodiment provides a camera accessory 200, which is detachably disposed on the outer surface of the housing 10 of the shooting device 100 of the gimbal camera. The camera accessory 200 includes an accessory body 40, a third connecting part and a fourth connecting part 50. The third connecting part is used for mechanical coupling with the first connecting part of the shooting device 100 of the gimbal camera. When the camera accessory 200 is mechanically coupled with the shooting device 100, the camera accessory 200 forms an electrical connection with the gimbal camera through the fourth connecting part 50.

[0091] The camera accessory 200 provided in this embodiment may include various structures of the camera accessory 200 provided in any of the foregoing embodiments of this disclosure.

[0092] The camera accessory 200 includes a first type accessory 200a and a second type accessory 200b. The first type accessory 200a is an electronic accessory with adjustable optical parameters, while the second type accessory 200b has non-adjustable optical parameters. In one example, the first type accessory 200a includes, but is not limited to, a fill light module and an electronic neutral density filter, while the second type accessory 200b includes, but is not limited to, a soft-focus filter and a wide-angle filter.

[0093] Among them, such as Figure 3 and Figure 6As shown, the first type accessory 200a includes a drive module 70, which is electrically connected to either a third signal terminal 51 or a fourth signal terminal 54. It should be noted that when the third signal terminal 51 is time-division multiplexed and the fourth signal terminal 54 is not provided, the drive module 70 can be electrically connected to the third signal terminal 51; when the camera accessory 200 is provided with a fourth signal terminal 54, the drive module 70 can be electrically connected to the fourth signal terminal 54. For example, the first type accessory 200a is an electronic neutral density (ND) filter. Its transmittance can be adjusted by regulating the electric field strength of the ND filter. Users can adjust the transmittance of the ND filter according to the ambient light intensity to change the ambient light entering the lens section 20. In this embodiment, the drive module 70 is configured to adjust the optical parameters of the first type accessory 200a to enable the same camera accessory 200 to meet the needs of various scenarios.

[0094] In some embodiments, the first type of accessory is a fill light module, which includes a light-emitting element, a dimming element, and a light-transmitting element. The light-emitting element serves as a light source to provide fill light. The dimming element and the light-transmitting element are both disposed on the light path of the light-emitting element to adjust the light emitted by the light-emitting element so that the light ultimately emitted outside the fill light module meets the requirements.

[0095] The light-transmitting element is located on the side of the dimming element that faces away from the light-emitting element. As the structure of the supplementary lighting module that comes into contact with the external environment, the light-transmitting element serves to transmit light and protect the dimming element. In one example, the light-transmitting element can be a transparent glass plate or an acrylic plate.

[0096] A dimming element can adjust the emission angle of light, thereby adjusting the illumination range and distance. For example, a dimming element can focus light to illuminate a farther distance, or it can disperse light to illuminate a closer distance. In some embodiments, the dimming element includes a polymer-dispersed liquid crystal (PDLC). By adjusting the electric field applied to the PDLC, the haze of the PDLC can be adjusted. When the haze of the PDLC is large, the emitted light can have a larger angle to easily cover nearby objects; when the haze of the PDLC is small, the emitted light can have a smaller angle to illuminate distant objects.

[0097] In some embodiments, the supplementary lighting module further includes a light guide element disposed between the light-emitting element and the dimming element, along the light-emitting direction of the light-emitting element. The light guide element can guide and focus the light emitted by the light-emitting element to the dimming element, thereby improving the utilization rate of the diffused light emitted by the light guide element. The light guide element can be made of, for example, transparent colloid or acrylic material.

[0098] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the embodiments disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
