Detailed Implementation

[0072] 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 numbers 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 invention. Rather, they are merely examples of methods consistent with some aspects of this invention as detailed in the appended claims. It should also be understood that the term "and / or" as used in this invention refers to and includes any or all possible combinations of one or more associated listed items.

[0073] The image capture system disclosed herein is a system in which an image capture device and an external device can be combined and separated, allowing users to take pictures in different ways; for example, a split-type camera is one such product form. When the image capture device and the external device are combined, the user can use the image capture device to take pictures by hand-holding the external device. In addition, the external device can also power the image capture device and communicate with it. When the image capture device and the external device are separated, the user can take pictures by fixing the image capture device in place. For example, the image capture device can be fixed to objects such as bicycles, backpacks, and tripods using various accessories.

[0074] In related technologies, an image capture system is provided, such as Figure 1 As shown, the image capture system 10 includes an image capture device 20 and an external device 30. The image capture device 20 and the external device 30 can be combined or separated. The external device 30 is equipped with a detection switch S that passes through its surface, and the detection switch S is used to detect the presence of the image capture device 20. When the image capture device 20 is separated from the external device 30, the detection switch S is not under force and is in the open state, and the detection signal of the external device 30 is the first signal. When the external device 30 detects that the image capture device 20 is not in place, it stops supplying power to the image capture device 20 and stops communicating with the image capture device 20. When the image capture device 20 is combined with the external device 30, the detection switch S is under force and is in the closed state, and the detection signal of the external device 30 is the second signal. When the external device 30 detects that the image capture device 20 is in place, it supplies power to the image capture device 20 and communicates with the image capture device 20. However, since an opening needs to be made on the surface of the external device 30 to install the detection switch S, water can easily enter through the opening, which reduces the waterproof performance of the external device 30. Furthermore, since the detection switch S passes through the surface of the external device 30 and is exposed when the image capture device 20 is separated from the external device 30, the aesthetics of the external device 30 are reduced.

[0075] Based on this, the present disclosure provides an image capture device that, by altering the characteristics of the external device as it approaches it, replaces the method of detecting whether a force is applied to the detection switch, thus achieving in-situ detection of the image capture device. This eliminates the need for the external device to have an opening for a detection switch, thereby improving the waterproof performance of the external device. Furthermore, since there is no need for a detection switch that penetrates the external device, the detection switch is not exposed when the image capture device is separated from the external device, improving the aesthetics of the external device.

[0076] This disclosure provides an exemplary embodiment of an image capture device, such as... Figure 2 As shown, the image capture device 20 includes a first housing 21 and a first trigger unit 22. The first trigger unit 22 is disposed in the first housing 21, and the distance between the first trigger unit 22 and an external device is a first distance. When the first distance is less than a first threshold, the detection signal of the external device changes.

[0077] In this embodiment, the image capture device includes a first housing and a first trigger portion disposed within the first housing. When the first trigger portion approaches an external device, it alters the characteristics of the external device, causing a change in the detection signal of the external device to detect the presence of the image capture device. Because the first trigger portion can change the detection signal for presence detection when it approaches the external device, there is no need to provide a detection device that penetrates the second housing of the external device, thereby improving the waterproof performance of the external device. Simultaneously, the elimination of a detection device that penetrates the second housing of the external device enhances its aesthetics.

[0078] For example, the image capture device 20 also includes physical structures such as a camera. The camera or other physical structures may be disposed on the first housing 21 and located on the first surface of the first housing 21, and the first trigger portion 22 may be located on the second surface of the first housing 21, with the first surface facing away from the second surface. Alternatively, the first trigger portion 22 may also be located inside the first housing 21.

[0079] For example, the first distance can be the distance between the image capturing device 20 and the detection device in the external device, or it can be the distance between the image capturing device 20 and the surface of the second housing in the external device.

[0080] For example, the value range of the first threshold can be 0.2cm to 3cm. The value of the first threshold can be 0.5cm, 1cm, 2cm, etc.

[0081] In one embodiment, the image capture device 20 further includes a first fixing structure 23. The first fixing structure 23 is disposed on the surface of the first housing 21, and the image capture device 20 is detachably connected to an external device through the first fixing structure 23.

[0082] In this embodiment, when the image capture device needs to be used in combination with an external device, the first fixing structure can securely connect the image capture device to the external device, preventing the image capture device from slipping off and being damaged, thus improving the reliability of the image capture device. When the image capture device needs to be used separately from the external device, the first fixing structure can detach the image capture device from the external device, preventing the image capture device from being difficult to detach from the external device and improving the user experience.

[0083] For example, the number of first fixing structures 23 can be one or more. When there are multiple first fixing structures 23, the multiple first fixing structures 23 can be symmetrically arranged to improve the reliability of the connection between the image capture device 20 and the external device.

[0084] In one embodiment, the image capture device 20 further includes a first electrical connection structure 24. The first electrical connection structure 24 is disposed on the surface of the first housing 21 and is used for electrical connection with a second electrical connection structure of an external device.

[0085] In this embodiment, when the image capture device and the external device are used in combination, the electrical connection between the first electrical connection structure and the second electrical connection structure enables the transmission of signals between the image capture device and the external device, thereby improving the convenience of using the image capture device.

[0086] For example, the image capture device 20 and the external device can communicate, power supply and in-situ detection functions through the first electrical connection structure 24 and the second electrical connection structure.

[0087] In one embodiment, the first electrical connection structure 24 includes a plurality of first electrical connection terminals. The number of first electrical connection terminals is greater than two.

[0088] In this embodiment, since there are multiple first electrical connection terminals, different signals can be transmitted between the image capture device and the external device through the multiple first electrical connection terminals, enabling the image capture device and the external device to perform multiple functions when used together, thereby improving the user experience.

[0089] For example, the number of first electrical connection terminals can be 3, 4, 5, 6, 7, 8, etc.

[0090] For example, when the number of first electrical connection terminals is 6, 2 first electrical connection terminals are used for power supply, 3 first electrical connection terminals are used for communication, and 1 first electrical connection terminal is used for in-situ detection.

[0091] In one embodiment, the first trigger unit 22 is used to engage the image capture device 20 with an external device when it is in a preset orientation, and to repel the external device when it deviates from the preset orientation. In the preset orientation, each first electrical connection terminal corresponds to each second electrical connection terminal of the external device.

[0092] In this embodiment, due to the large number of first electrical connection terminals, when the image capture device is combined with an external device, there may be instances where the first electrical connection terminals are electrically connected to mismatched second electrical connection terminals, causing the image capture device and the external device to be unable to be used together or even to be damaged. By ensuring that the image capture device only engages with the external device in a preset orientation, each first electrical connection terminal can be electrically connected to a matching second electrical connection terminal, thereby improving the reliability of the image capture device.

[0093] In one embodiment, the first trigger part 22 is made of magnetic material. When the image capturing device 20 is in a preset orientation, there is an attractive force between the first trigger part 22 and the external device, and the image capturing device 20 engages with the external device through the attractive force.

[0094] In this embodiment, because there is an attractive force between the image capture device and the external device when the image capture device is in a preset orientation, the image capture device and the external device can attract each other and combine in the correct manner, thereby improving the reliability of the image capture device and reducing the difficulty of combining the image capture device and the external device. Furthermore, because the magnetic material is magnetic, when the first distance is less than a first threshold, it changes the magnetic field of the external device, triggering a change in the detection signal, thereby improving the reliability of in-situ detection. Moreover, by reusing the first trigger part, which is the magnetic material, for in-situ detection and combination, the number of devices is reduced, thereby reducing the complexity of the image capture device structure.

[0095] In one embodiment, the first trigger part 22 is made of magnetic material. When the image capture device 20 is not in a preset position, there is a repulsive force between the first trigger part 22 and the external device, and the image capture device 20 repels the external device through the repulsive force.

[0096] In this embodiment, since there is a repulsive force between the image capture device and the external device when the image capture device is not in the preset position, the image capture device and the external device repel each other and avoid being combined in the wrong way, thereby improving the reliability of the image capture device.

[0097] For example, if the magnetic pole of the first trigger part 22 is N in one area and S in another area, when the image capturing device 20 is in a preset orientation, the two areas of the external device corresponding to the first trigger part 22 are provided with second trigger parts with magnetic poles S and N respectively to generate an attractive force. When the image capturing device 20 is not in the preset orientation, the two areas of the external device corresponding to the first trigger part 22 are provided with second trigger parts with magnetic poles N and S respectively to generate a repulsive force.

[0098] For example, when the image capturing device 20 is fully placed on the external device along a preset orientation, the magnetic field of the external device changes.

[0099] An exemplary embodiment of this disclosure provides an external device, such as Figure 3 As shown, the external device 30 includes a second housing 31 and a detection device 32. The detection device 32 is disposed in the second housing 31, and the distance between the detection device 32 and the first trigger part 22 of the image capture device 20 is a second distance. When the second distance is less than a second threshold, the detection signal of the detection device 32 changes.

[0100] In this embodiment, the external device includes a second housing and a detection device disposed within the second housing. When the image capture device approaches the detection device, it alters the characteristics of the external device, triggering a change in the detection signal of the detection device to detect the presence of the image capture device. Because the image capture device can change its detection signal for presence detection when it approaches the external device, there is no need to install a detection device that penetrates the second housing, thereby improving the waterproof performance of the external device. Simultaneously, the elimination of a detection device penetrating the second housing of the external device enhances its aesthetics.

[0101] For example, the value range of the second threshold can be 0.2cm to 3cm. The value of the second threshold can be 0.5cm, 1cm, 2cm, etc. The first threshold can be the same as the second threshold or different from the second threshold.

[0102] Exemplarily, the second housing 31 may also include physical structures such as a charging interface, for example, a Type-C interface. The second housing 31 may be provided with a recess for accommodating the image capture device 20, so that the image capture device 20 and the external device 30 can be used together. The detection device 32 may be located inside the recess or on the surface of the recess.

[0103] In one embodiment, the external device 30 further includes a second fixing structure 33. The second fixing structure 33 is disposed on the surface of the second housing 31, and the external device 30 is detachably connected to the image capture device 20 through the second fixing structure 33.

[0104] In this embodiment, when the image capture device needs to be used in combination with an external device, the second fixing structure can securely connect the image capture device and the external device, preventing the image capture device from slipping off and being damaged, thus improving the reliability of the external device. When the image capture device needs to be used separately from the external device, the second fixing structure can detach the image capture device from the external device, preventing the image capture device from being difficult to detach from the external device and improving the user experience.

[0105] For example, the number of second fixing structures 33 can be one or more. When there are multiple second fixing structures 33, the multiple second fixing structures 33 can be symmetrically arranged to improve the reliability of the connection between the external device 30 and the image capture device 20.

[0106] In one embodiment, the external device 30 further includes a second electrical connection structure 34. The second electrical connection structure 34 is disposed on the surface of the second housing 31 and is used for electrical connection with the first electrical connection structure 24 of the image capture device 20.

[0107] In this embodiment, when the image capture device and the external device are used in combination, the electrical connection between the first electrical connection structure and the second electrical connection structure enables the transmission of signals between the image capture device and the external device, thereby improving the convenience of using the external device.

[0108] For example, the image capture device 20 and the external device 30 can achieve functions such as communication, power supply and presence detection through the first electrical connection structure 24 and the second electrical connection structure 34.

[0109] In one embodiment, the second electrical connection structure 34 includes a plurality of second electrical connection terminals. The number of second electrical connection terminals is greater than two.

[0110] In this embodiment, since there are multiple second electrical connection terminals, different signals can be transmitted between the external device and the image capture device through the multiple second electrical connection terminals, enabling the image capture device to perform multiple functions when used in combination with the external device, thereby improving the user experience.

[0111] For example, the number of second electrical connection terminals can be 3, 4, 5, 6, 7, 8, etc.

[0112] For example, when the number of second electrical connection terminals is 6, 2 second electrical connection terminals are used for power supply, 3 second electrical connection terminals are used for communication, and 1 second electrical connection terminal is used for in-situ detection.

[0113] In one embodiment, the external device 30 further includes a second trigger. The second trigger is disposed in the second housing 31 and is used to engage the external device 30 with the image capture device 20 in a preset orientation and to repel the image capture device 20 when deviating from the preset orientation. In the preset orientation, each second electrical connection terminal corresponds to each first electrical connection terminal of the image capture device 20.

[0114] In this embodiment, due to the large number of second electrical connection terminals, when the image capture device is combined with an external device, there may be instances where the second electrical connection terminals are electrically connected to mismatched first electrical connection terminals, causing the image capture device and the external device to be unable to be used together or even to be damaged. By ensuring that the external device only engages with the image capture device in a preset orientation, each second electrical connection terminal can be electrically connected to a matching first electrical connection terminal, thereby improving the reliability of the external device.

[0115] For example, the second trigger portion may be located inside the groove or on the surface of the groove.

[0116] In one embodiment, the second trigger is made of a magnetic material. When the external device 30 is in a preset orientation, there is an attractive force between the second trigger and the image capture device 20, and the external device 30 engages with the image capture device 20 through this attractive force.

[0117] In this embodiment, because there is an attractive force between the external device and the image capture device when they are in a preset orientation, the image capture device and the external device can attract each other and combine in the correct manner, thereby improving the reliability of the image capture device and reducing the difficulty of combining the image capture device and the external device. Moreover, because the magnetic material is magnetic, when the second distance is less than the second threshold, it will change the magnetic field of the external device and trigger a change in the detection signal, thereby improving the reliability of in-situ detection.

[0118] In one embodiment, the second trigger part is made of magnetic material. When the external device 30 is not in a preset position, there is a repulsive force between the second trigger part and the image capture device 20, and the external device 30 repels the image capture device 20 through the repulsive force.

[0119] In this embodiment, since there is a repulsive force between the external device and the image capture device when the external device is not in the preset position, the external device and the image capture device repel each other and avoid being combined in the wrong way, thereby improving the reliability of the image capture device.

[0120] For example, if the magnetic pole of the second trigger unit is S in one area and N in another area, when the external device 30 is in a preset orientation, the image capture device 20 corresponding to the second trigger unit has a first trigger unit 22 with magnetic poles N and S in two areas to generate an attractive force. When the external device 30 is not in the preset orientation, the image capture device 20 corresponding to the second trigger unit has a first trigger unit 22 with magnetic poles S and N in two areas to generate a repulsive force.

[0121] In one embodiment, such as Figure 4 As shown, the detection device 32 includes a Hall effect detection module 321 and a terminal detection module 322. The first input terminal of the terminal detection module 322 is electrically connected to the output terminal of the Hall effect detection module 321.

[0122] In this embodiment, the voltage signal output by the Hall effect detection module differs depending on whether the characteristics of the external device change or remain unchanged. By using the terminal detection module to perform presence detection based on the voltage signal, the presence of the image capture device can be identified, thereby improving the reliability of presence detection.

[0123] In one embodiment, the second input terminal of the terminal detection module 322 is electrically connected to the second electrical connection terminal in the second electrical connection structure 34, and the output terminal of the terminal detection module 322 is used to be electrically connected to the microcontroller MCU.

[0124] In this embodiment, by electrically connecting the second input terminal of the terminal detection module to the second electrical connection terminal in the second electrical connection structure, the detection signal can change when the second electrical connection terminal is electrically connected to the first electrical connection terminal, thereby avoiding the image capture device from being out of place and causing the detection signal to change erroneously, thus improving the reliability of in-place detection.

[0125] In one embodiment, the detection device 32 includes a Hall effect detection module 321 and a terminal detection module 322. A first input terminal of the terminal detection module 322 is electrically connected to the output terminal of the Hall effect detection module 321. A second input terminal of the terminal detection module 322 is electrically connected to a second electrical connection terminal in the second electrical connection structure 34, and the output terminal of the terminal detection module 322 is used for electrical connection with a microcontroller (MCU).

[0126] In this embodiment, the voltage signal output by the Hall effect detection module differs depending on whether the characteristics of the external device change or remain unchanged. By using the terminal detection module to perform presence detection based on the voltage signal, the presence or absence of the image capture device can be identified, thereby improving the reliability of presence detection. By electrically connecting the second input terminal of the terminal detection module to the second electrical connection terminal in the second electrical connection structure, the detection signal can change even when the second electrical connection terminal is electrically connected to the first electrical connection terminal. This avoids erroneous changes in the detection signal due to the image capture device not being in place, further improving the reliability of presence detection.

[0127] In one embodiment, such as Figure 5 As shown, the Hall detection module 321 includes a Hall sensor H and a comparator circuit 3211. The first input terminal of the comparator circuit 3211 is electrically connected to the output terminal of the Hall sensor H, and the output terminal of the comparator circuit 3211 is electrically connected to the first input terminal of the terminal detection module 322.

[0128] In this embodiment, by electrically connecting the Hall sensor to the comparison circuit, the comparison circuit outputs a high-level signal or a low-level signal based on the voltage signal output by the Hall sensor. The terminal detection module realizes in-situ detection based on the high-level signal and low-level signal output by the comparison circuit, thereby reducing the complexity of in-situ detection.

[0129] For example, the second input terminal of the comparator circuit 3211 is electrically connected to the input power supply after voltage division by the voltage divider circuit. When the voltage at the first input terminal is greater than the voltage at the second input terminal, the comparator circuit 3211 outputs a high-level signal. When the voltage at the first input terminal is less than the voltage at the second input terminal, the comparator circuit 3211 outputs a low-level signal.

[0130] For example, the comparator circuit 3211 may include a comparator and its peripheral circuitry.

[0131] In one embodiment, such as Figure 6 and Figure 7 As shown, there are multiple Hall effect detection modules 321. The detection device 32 also includes logic gate circuits 323. Each input terminal of the logic gate circuit 323 is electrically connected to the output terminal of one Hall effect detection module 321, and the output terminal of the logic gate circuit 323 is electrically connected to the first input terminal of the terminal detection module 322.

[0132] In this embodiment, since each Hall detection module can detect whether a region of the image capture device is in place, by setting multiple Hall detection modules and logic gate circuits, it is possible to detect whether multiple regions of the image capture device are in place simultaneously, thereby improving the accuracy of in-place detection.

[0133] For example, logic gate 323 may include AND gates, OR gates, or combinations thereof.

[0134] For example, the first terminal of logic gate 323 is electrically connected to the input power supply Vin, and the second terminal is electrically connected to the ground terminal GND.

[0135] For example, such as Figure 8 As shown, the detection device 32 includes a Hall effect detection module 321 and a terminal detection module 322. The Hall effect detection module 321 includes a Hall sensor H, a comparator CO, a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a fifth resistor R5, a first capacitor C1, a second capacitor C2, a third capacitor C3, and a fourth capacitor C4. The terminal detection module 322 includes a first transistor T1, a second transistor T2, a first diode D1, a second diode D2, a sixth resistor R6, a seventh resistor R7, and an eighth resistor R8. The first terminal of the first resistor R1 is electrically connected to the input power supply Vin, and the second terminal of the first resistor R1 is electrically connected to the first terminal of the first capacitor C1 and the first terminal of the Hall sensor H. The output terminal of the Hall sensor H is electrically connected to the first terminals of the second capacitor C2, the third capacitor C3, the second resistor R2, and the first terminal of the comparator CO. The second terminal of comparator CO is electrically connected to the first terminals of the third resistor R3 and the fourth resistor R4. The third terminal of comparator CO is electrically connected to the input power supply Vin, the second terminals of the second resistor R2 and the third resistor R3, the first terminal of the fourth capacitor C4, and the first terminal of the fifth resistor R5. The output terminal of comparator CO is electrically connected to the second terminal of the fifth resistor R5 and the gate of the first transistor T1. The second terminals of the first capacitor C1, the Hall sensor H, the second capacitor C2, the third capacitor C3, the fourth resistor R4, the fourth capacitor C4, and the fourth terminal of comparator CO are all electrically connected to the ground terminal GND. The source of the first transistor T1 is electrically connected to the second electrical connection terminal P and the anode of the first diode D1. The drain of the first transistor T1 is electrically connected to the gate of the second transistor T2, the cathode of the first diode D1, and the first terminal of the sixth resistor R6. The second terminal of the sixth resistor R6 is electrically connected to the input power supply Vin and the first terminal of the seventh resistor R7. The source of the second transistor T2 is electrically connected to the second terminal of the seventh resistor R7 and the cathode of the second diode D2. The drain of the second transistor T2 is electrically connected to the first terminal of the eighth resistor R8, the anode of the second diode D2, and the microcontroller MCU. The second terminal of the eighth resistor R8 is used to connect to the ground terminal GND. The first electrical connection terminal, which is electrically connected to the second electrical connection terminal P, is used to connect to the ground terminal in the image capture device 20.

[0136] For example, when the second distance is greater than or equal to the second threshold, the magnetic field of the external device 30 remains unchanged, and the voltage output by the Hall sensor H is the first voltage U1. That is, the voltage at the first terminal of the comparator CO is the first voltage U1, and the voltage at the second terminal of the comparator CO is the second voltage U2. Since U1 is less than U2, the output terminal of the comparator CO outputs a low-level signal, the first transistor T1 cannot be turned on, the drain of the first transistor T1 is at a high level, the second transistor T2 cannot be turned on, and the level signal output to the microcontroller MCU is a low-level signal. Therefore, the external device 30 detects that the image capture device 20 is not in place. When the second distance is less than the second threshold, the magnetic field of the external device 30 changes, and the voltage output by the Hall sensor H is the third voltage U3. That is, the voltage at the first terminal of the comparator CO is the third voltage U3, and the voltage at the second terminal of the comparator CO is the second voltage U2. Since U2 is less than U3, the output terminal of the comparator CO outputs a high-level signal, causing the first transistor T1 to turn on. When the second electrical connection terminal P is electrically connected to the corresponding first electrical connection terminal, the drain of the first transistor T1 is at a low level, causing the second transistor T2 to conduct, and the level signal output to the microcontroller MCU is a high level signal. Therefore, the external device 30 detects that the image capture device 20 is in place.

[0137] In one embodiment, the external device 30 further includes a self-test module. The self-test module is electrically connected to the second electrical connection structure 34 and is used to perform an in-situ detection of the image capture device 20 via the second electrical connection structure 34.

[0138] In this embodiment, since the self-test module can also perform in-situ detection through the second electrical connection structure, the reliability of in-situ detection is improved by performing various in-situ detections on the image capture device through the self-test module and the detection device.

[0139] In one embodiment, the self-test module includes a polling detection circuit. The polling detection circuit is electrically connected to the second electrical connection structure 34, and is used to poll and detect each of the second electrical connection terminals in the second electrical connection structure 34.

[0140] In this embodiment, when the image capture device is in place, each second electrical connection terminal is electrically connected to its corresponding first electrical connection terminal. When the image capture device is not in place, at least some of the second electrical connection terminals are in a floating state. By detecting the level signal of the second electrical connection terminals through a polling detection circuit, it is possible to determine whether the image capture device is in place, thereby improving the reliability of the presence detection.

[0141] In one embodiment, the self-test module includes an impedance detection circuit, which is electrically connected to the second electrical connection structure 34. The impedance detection circuit is used to perform impedance detection on each of the second electrical connection terminals in the second electrical connection structure 34.

[0142] In this embodiment, when the image capture device is in place, each second electrical connection terminal is electrically connected to its corresponding first electrical connection terminal. When the image capture device is not in place, at least some of the second electrical connection terminals are in a floating state. By detecting the impedance value of each second electrical connection terminal through an impedance detection circuit, it is possible to determine whether the image capture device is in place, thereby improving the reliability of the presence detection.

[0143] In one embodiment, the self-test module includes a polling detection circuit and an impedance detection circuit. The polling detection circuit is electrically connected to the second electrical connection structure 34 and is used to poll and detect each of the second electrical connection terminals in the second electrical connection structure 34. The impedance detection circuit is also electrically connected to the second electrical connection structure 34 and is used to detect the impedance of each of the second electrical connection terminals in the second electrical connection structure 34.

[0144] In this embodiment, since the polling detection circuit and the impedance detection circuit can determine whether the image capture device is in place, the polling detection circuit and the impedance detection circuit work together with the detection device to perform in-place detection of the image capture device, thereby improving the reliability of in-place detection.

[0145] This disclosure provides an exemplary embodiment of an image capture system, such as... Figure 9 As shown, the image capture system 10 includes an image capture device 20 and an external device 30. The image capture device 20 includes a first housing 21 and a first trigger 22. The first trigger 22 is disposed in the first housing 21. The external device 30 includes a second housing 31 and a detection device 32. The detection device 32 is disposed in the second housing 31. The distance between the first trigger 22 and the detection device 32 is a second distance. When the second distance is less than a second threshold, the detection signal of the detection device 32 changes. This detection signal is used for the presence detection of the image capture device 20.

[0146] In this embodiment, the image capture system includes an image capture device and an external device. The image capture device includes a first housing and a first trigger portion disposed within the first housing. The external device includes a second housing and a detection device disposed within the second housing. When the first trigger portion approaches the detection device, it alters the characteristics of the external device, triggering a change in the detection signal of the detection device to detect the presence of the image capture device. Because the first trigger portion can change the detection signal for presence detection when it approaches the external device, there is no need to provide a detection device that penetrates the second housing of the external device, thereby improving the waterproof performance of the external device and the image capture system package. Simultaneously, the elimination of the need for a detection device penetrating the second housing of the external device enhances the aesthetics of the external device and the image capture system package.

[0147] For example, the first trigger 22 may be located on the second surface of the first housing 21 or inside the first housing 21. The detection device 32 may be located inside the second housing 31 or on the surface of the second housing 31.

[0148] For example, the value range of the second threshold can be 0.2cm to 3cm. The value of the second threshold can be 0.5cm, 1cm, 2cm, etc.

[0149] In one embodiment, the image capture device 20 further includes a first fixing structure 23. The first fixing structure 23 is disposed on the surface of the first housing 21. The external device 30 further includes a second fixing structure 33. The second fixing structure 33 is disposed on the surface of the second housing 31. The first fixing structure 23 and the second fixing structure 33 are detachably connected.

[0150] In this embodiment, when the image capture device needs to be used in combination with an external device, the first and second fixing structures can securely connect the image capture device to the external device, preventing the image capture device from slipping off and being damaged, thus improving the reliability of the image capture system. When the image capture device needs to be used separately from the external device, the first and second fixing structures can detach the image capture device from the external device, preventing the image capture device from being difficult to remove from the external device and improving the user experience.

[0151] For example, the number of first fixing structures 23 can be one or more. When there are multiple first fixing structures 23, the multiple first fixing structures 23 can be symmetrically arranged to improve the reliability of the connection between the image capture device 20 and the external device.

[0152] For example, the number of second fixing structures 33 can be one or more. When there are multiple second fixing structures 33, the multiple second fixing structures 33 can be symmetrically arranged to improve the reliability of the connection between the external device 30 and the image capture device 20.

[0153] In one embodiment, the image capture device 20 includes a first electrical connection structure 24. The first electrical connection structure 24 is disposed on the surface of the first housing 21. The external device 30 includes a second electrical connection structure 34. The second electrical connection structure 34 is disposed on the surface of the second housing 31, and the first electrical connection structure 24 is used for electrical connection with the second electrical connection structure 34.

[0154] In this embodiment, when the image capture device and the external device are used in combination, the electrical connection between the first electrical connection structure and the second electrical connection structure enables the transmission of signals between the image capture device and the external device, thereby improving the convenience of using the image capture system.

[0155] For example, the image capture device 20 and the external device 30 can achieve functions such as communication, power supply and presence detection through the first electrical connection structure 24 and the second electrical connection structure 34.

[0156] In one embodiment, the first electrical connection structure 24 includes a plurality of first electrical connection terminals, and the second electrical connection structure 34 includes a plurality of second electrical connection terminals, wherein the number of both the first electrical connection terminals and the second electrical connection terminals is greater than two.

[0157] In this embodiment, since there are multiple first electrical connection terminals and multiple second electrical connection terminals, the image capture device and the external device can transmit and receive different signals through multiple first electrical connection terminals and multiple second electrical connection terminals respectively, so that the image capture device and the external device can achieve multiple functions when used together, thereby improving the user experience.

[0158] For example, the number of the first electrical connection terminal and the second electrical connection terminal can be 3, 4, 5, 6, 7, 8, etc.

[0159] For example, when the number of first electrical connection terminals and second electrical connection terminals is 6, 2 first electrical connection terminals and 2 second electrical connection terminals are used for power supply, 3 first electrical connection terminals and 3 second electrical connection terminals are used for communication, and 1 first electrical connection terminal and 1 second electrical connection terminal are used for in-situ detection.

[0160] In one embodiment, the external device 30 further includes a second triggering unit. The second triggering unit is disposed in the second housing 31. The first triggering unit 22 and the second triggering unit are used to engage the image capture device 20 with the external device 30 in a preset orientation and to repel the external device 30 when deviating from the preset orientation. In the preset orientation, each first electrical connection terminal corresponds to each second electrical connection terminal.

[0161] In this embodiment, due to the large number of first and second electrical connection terminals, when the image capture device is combined with an external device, there may be instances where the second electrical connection terminals are electrically connected to mismatched first electrical connection terminals, causing the image capture device and the external device to be unusable together or even damaged. By ensuring that the image capture device only engages with the external device in a preset orientation, each second electrical connection terminal can be electrically connected to a matching first electrical connection terminal, thereby improving the reliability of the image capture system.

[0162] In one embodiment, both the first trigger part 22 and the second trigger part are made of magnetic materials. When both the image capture device 20 and the external device 30 are in a preset position, there is an attraction between the first trigger part 22 and the second trigger part, and the image capture device 20 engages with the external device 30 through the attraction.

[0163] In this embodiment, since there is an attractive force between the image capture device and the external device when they are both in a preset orientation, they can attract each other and combine in the correct manner, thereby improving the reliability of the image capture system and reducing the difficulty of combining the image capture device and the external device. Furthermore, because the magnetic material is magnetic, when the second distance is less than the second threshold, it changes the magnetic field of the external device, triggering a change in the detection signal, thereby improving the reliability of in-situ detection. Moreover, by reusing the first trigger part, which is the magnetic material, for in-situ detection and combination, the number of devices is reduced, thereby reducing the complexity of the image capture device structure.

[0164] In one embodiment, both the first trigger part 22 and the second trigger part are made of magnetic materials. When the image capture device 20 and / or the external device 30 are not in a preset position, there is a repulsive force between the first trigger part 22 and the second trigger part, and the image capture device 20 repels the external device 30 through the repulsive force.

[0165] In this embodiment, since there is a repulsive force between the image capture device and the external device when the image capture device and / or the external device are not in the preset position, the image capture device and the external device repel each other and avoid being combined in the wrong way, thereby improving the reliability of the image capture system.

[0166] For example, if the magnetic pole of the second trigger part is S in one area and N in another area, when both the external device 30 and the image capture device 20 are in a preset orientation, a first trigger part 22 with magnetic poles N and S in two areas of the image capture device 20 corresponding to the second trigger part is provided to generate an attractive force. When the external device 30 and / or the image capture device 20 are not in the preset orientation, a first trigger part 22 with magnetic poles S and N in two areas of the image capture device 20 corresponding to the second trigger part is provided to generate a repulsive force.

[0167] For example, such as Figures 8 to 12 As shown, when the image capture device 20 and the external device 30 in the image capture system 10 are Figure 9 In the separated state shown, the detection signal received by the microcontroller MCU is a low-level signal, indicating that the image capture device 20 is not in place. When the image capture device 20 and the external device 30 in the image capture system 10 are... Figure 10 In the combined state shown, the detection signal received by the microcontroller MCU is a high-level signal, indicating that the image capture device 20 is in place. For example... Figure 11 and Figure 12As shown, during the combination of image capture device 20 and external device 30, the microcontroller MCU detects a low-level signal, indicating that image capture device 20 is not in place. Only when image capture device 20 and external device 30 are correctly combined... Figure 10 The microcontroller MCU receives a high-level detection signal, indicating that the image capture device 20 is in place.

[0168] For example, the preset orientation includes, for instance, the preset orientation. Figure 10 The orientations of the image capture device 20 and the external device 30 are shown. When the image capture device 20 or the external device 30 is adjusted at angles such as 45 degrees, 90 degrees, 80 degrees, and 270 degrees, the image capture device 20 or the external device 30 is no longer in the preset orientation. If... Figure 10 If the image capture device 20 or the external device 30 is adjusted to the same angle, both the image capture device 20 and the external device 30 will be in the preset orientation.
