DETAILED DESCRIPTION

[0041] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the utility model. On the contrary, they are only examples of devices and methods consistent with some aspects of the utility model as detailed in the attached claims. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0042] At present, when an electronic device is shooting a picture, the camera module detects the jitter data of the electronic device based on the inertial measurement unit and performs displacement compensation to avoid blurring of the shooting picture caused by the jitter of the electronic device. For example, the camera module detects the jitter data generated by the jitter of the electronic device through the inertial measurement unit and transmits the jitter data to the smart sensor hub (Sensor Hub) or the camera. The smart sensor hub or the camera calculates the displacement that needs to be compensated and controls the camera lens to move the corresponding displacement to eliminate the impact of the jitter of the electronic device. Figure 1As shown, the camera module includes an inertial measurement unit 10, a first camera 20, a second camera 30 and an intelligent sensor hub 40. The first end of the inertial measurement unit 10 is used to be electrically connected to the first power supply VDD1, the second end of the inertial measurement unit 10 is electrically connected to the first end of the first camera 20 and the first end of the intelligent sensor hub 40, and the third end of the inertial measurement unit 10 is electrically connected to the third end of the intelligent sensor hub 40. The second end of the intelligent sensor hub 40 is electrically connected to the first end of the second camera 30. The second end of the first camera 20 is used to be electrically connected to the third power supply VDD3. The second end of the second camera 30 is used to be electrically connected to the third power supply VDD3. Since the second end of the inertial measurement unit 10 is electrically connected to the first end of the first camera 20 and the first end of the intelligent sensor hub 40, only one of the first camera 20 and the intelligent sensor hub 40 can be used as a master device, and the other can be used as a slave device. After the electronic device is turned on, the first power supply VDD1 supplies power to the inertial measurement unit 10, and the third power supply VDD3 does not supply power to the first camera 20. When the first camera 20 acts as a slave device, the electronic device may not be able to recognize or stably recognize the jitter data detected by the inertial measurement unit 10, resulting in low stability of the camera module.

[0043] In the related art, a camera module is provided, which includes the inertial measurement unit 10, the first camera 20, the second camera 30 and the smart sensor hub 40 as described above. After the electronic device is turned on, the third power supply VDD3 supplies power to the first camera 20 so that the electronic device can recognize the jitter data detected by the inertial measurement unit 10. However, since the third power supply VDD3 supplies power to the first camera 20 and the second camera 30 at the same time, the second camera 30 generates unnecessary power consumption, which increases the power consumption of the camera module and may cause leakage of the second camera 30. In addition, in the process of shooting pictures by the electronic device, according to different shooting modes, one or more of the first camera 20 and the second camera 30 are required to capture images. Since the third power supply VDD3 supplies power to the first camera 20 and the second camera 30 at the same time, there is a situation where power is supplied to the camera that does not need to capture images, resulting in an increase in the power consumption of the camera module.

[0044] Based on this, the present disclosure provides a camera module, in which the first camera and the second camera are powered by different power supplies. Since in the process of shooting pictures by the electronic device, the power supply can selectively supply power to the first camera and / or the second camera according to different shooting modes, the extra power consumption caused by supplying power to the first camera and the second camera at the same time is avoided, thereby reducing the power consumption of the camera module and the possibility of leakage. At the same time, after the electronic device is turned on, it is necessary to identify the jitter data detected by the inertial measurement unit in order to perform anti-shake according to the jitter data. By supplying power to the first camera alone through the second power supply, the electronic device can reliably identify the jitter data detected by the inertial measurement unit after it is turned on, thereby improving the stability of the camera module.

[0045] An exemplary embodiment of the present disclosure provides a camera module, such as Figure 2 As shown, the camera module includes an inertial measurement unit 10, a first camera 20 and a second camera 30. The first end of the inertial measurement unit 10 is used to be electrically connected to the first power supply VDD1. The first end of the first camera 20 is electrically connected to the second end of the inertial measurement unit 10, and the second end of the first camera 20 is used to be electrically connected to the second power supply VDD2. The second camera 30 is used to be electrically connected to the third power supply VDD3.

[0046] In the present embodiment, the camera module includes an inertial measurement unit, a first camera and a second camera. The inertial measurement unit is electrically connected to the first power supply and the first camera, the first camera is used to be electrically connected to the second power supply, and the second camera is used to be electrically connected to the third power supply. By splitting and reorganizing the power supply, the first camera and the second camera can be powered respectively. Then, during the shooting process, the first camera and / or the second camera can be selectively powered according to the shooting mode, avoiding powering the first camera and the second camera at the same time, thereby reducing the power consumption of the camera module. At the same time, after the electronic device is turned on, it is necessary to identify the jitter data detected by the inertial measurement unit so as to perform anti-shake according to the jitter data. By supplying power to the first camera alone through the second power supply, the electronic device can reliably identify the jitter data detected by the inertial measurement unit after it is turned on, thereby improving the stability of the camera module.

[0047] In one embodiment, if Figure 3 As shown, the first camera 20 includes a first control unit 21, a first drive circuit 22, a first motor 23 and a first lens 24. The first end of the first control unit 21 is electrically connected to the second end of the inertial measurement unit 10. The first end of the first drive circuit 22 is electrically connected to the second end of the first control unit 21. The first end of the first motor 23 is electrically connected to the second end of the first drive circuit 22. The first lens 24 is connected to the second end of the first motor 23.

[0048] In this embodiment, since the inertial measurement unit can detect the jitter data generated by the electronic device due to jitter, the first control unit can calculate the displacement that needs to be compensated for the first lens according to the jitter data. The first control unit transmits the signal corresponding to the displacement to the first drive circuit, and the first drive circuit can control the first motor to drive the first lens to move according to the signal corresponding to the displacement, which can not only achieve fast focusing of the first camera, but also improve the anti-shake effect of the first camera.

[0049] In one embodiment, if Figure 4 As shown, there are multiple second cameras 30. Some of the second cameras 30 are first sub-cameras 31, and some of the second cameras 30 are second sub-cameras 32. The camera module also includes a second control unit 50. A first end of the second control unit 50 is electrically connected to a second end of the inertial measurement unit 10, and a second end of the second control unit 50 is electrically connected to a first end of the first sub-camera 31.

[0050] In this embodiment, by electrically connecting the first sub-camera to the second control unit, the second control unit can control the first sub-camera to perform displacement compensation based on the jitter data detected by the inertial measurement unit, thereby improving the anti-shake effect of the first sub-camera. Relative to the first camera, the second control unit located outside the first sub-camera can avoid the interference of the first sub-camera on the second control unit when calculating the displacement compensation, thereby improving the accuracy of the displacement compensation of the first sub-camera. Moreover, in the case where both the first camera and the first sub-camera need to be anti-shake, the second control unit and the first camera are electrically connected to the second end of the inertial measurement unit, so that the second control unit is used as the master device and the first camera is used as the slave device, then when the first camera and the first sub-camera are turned on at the same time, they can each realize the anti-shake function to improve the anti-shake effect of the camera module.

[0051] It is understandable that, unlike the first camera 20 , the first sub-camera 31 does not include a control unit, so the first sub-camera 31 needs to rely on the second control unit 50 to calculate the displacement based on the jitter data to achieve the anti-shake function.

[0052] In one embodiment, the number of the first camera 20 and / or the first sub-camera 31 is multiple. The first end of each first camera 20 is electrically connected to the second end of the inertial measurement unit 10, and the second end of each first camera 20 is used to be electrically connected to the second power supply VDD2. The first end of each first sub-camera 31 is electrically connected to different ends of the second control unit 50, and the second end of each first sub-camera 31 is used to be electrically connected to the third power supply VDD3. The second sub-camera 32 is used to be electrically connected to the third power supply VDD3.

[0053] In this embodiment, since there are multiple first cameras and each of them includes a first control unit, by electrically connecting each first camera to the inertial measurement unit and the second power supply, each first camera can not only achieve an anti-shake function, but also reduce the complexity of powering the first camera. Since there are multiple first sub-cameras, by electrically connecting each first sub-camera to the third power supply and to different ends of the second control unit, each first sub-camera can not only achieve an anti-shake function, but also reduce the complexity of powering the first sub-camera. Moreover, in some scenes where the camera module does not need to output images, by supplying power to the first sub-camera, the anti-shake function of the first sub-camera can be used to stabilize its lens, so that when the user actually needs to take a picture, the camera module can respond quickly and take a clear and stable picture.

[0054] Exemplarily, there are a plurality of second sub-cameras 32. Each second sub-camera 32 is used to be electrically connected to the third power supply VDD3.

[0055] In one embodiment, if Figure 5 As shown, the first sub-camera 31 includes a second driving circuit 311, a second motor 312, and a second lens 313. The first end of the second driving circuit 311 is electrically connected to the second end of the second control unit 50. The first end of the second motor 312 is electrically connected to the second end of the second driving circuit 311. The second lens 313 is connected to the second end of the second motor 312.

[0056] In this embodiment, since the inertial measurement unit can detect the jitter data generated by the electronic device due to jitter, and the second control unit can calculate the displacement that needs to be compensated for the second lens according to the jitter data, the second control unit transmits the signal corresponding to the displacement to the second drive circuit, and the second drive circuit can control the second motor to drive the second lens to move according to the signal corresponding to the displacement, which can not only achieve fast focusing of the first sub-camera, but also improve the anti-shake effect of the first sub-camera.

[0057] Exemplarily, the first driving circuit 22 and the second driving circuit 311 may include a driving chip.

[0058] In one embodiment, a third terminal of the second control unit 50 is electrically connected to a third terminal of the inertial measurement unit 10 .

[0059] In this embodiment, by electrically connecting the third end of the second control unit to the third end of the inertial measurement unit, the inertial measurement unit can detect posture data such as the direction and tilt angle of the electronic device and transmit the posture data to the second control unit, so that the screen of the electronic device can automatically adjust as the electronic device rotates, thereby improving the user experience.

[0060] In one embodiment, the second end of the inertial measurement unit 10 is electrically connected to the first end of the first camera 20 and the first end of the second control unit 50 through the first communication bus, and the third end of the inertial measurement unit 10 is electrically connected to the third end of the second control unit 50 through the second communication bus. The second end of the second control unit 50 is electrically connected to the first sub-camera 31 through the third communication bus. The communication protocols corresponding to the first communication bus and the second communication bus are the same, and the communication protocols corresponding to the first communication bus and the third communication bus are different.

[0061] In this embodiment, since the communication protocols corresponding to the first communication bus and the second communication bus are the same, the second control unit and the first sub-camera can obtain the jitter data of the electronic device detected by the inertial measurement unit, and the second control unit can obtain the posture data of the electronic device. Since the jitter data and posture data need to be transmitted at high speed, the first communication bus and the second communication bus correspond to the same communication protocol. Since the second control unit is not only electrically connected to the first sub-camera, but also electrically connected to other devices in the electronic device, the first communication bus and the third communication bus correspond to different communication protocols. By using communication buses with different communication protocols to transmit data in different situations, the first camera and the first sub-camera can reliably perform anti-shake, thereby improving the reliability of the camera module.

[0062] Exemplarily, the first communication bus and the second communication bus may be a serial peripheral interface (SPI) bus, and the third communication bus may be an integrated circuit (IIC) bus.

[0063] Exemplarily, after the initialization of the inertial measurement unit 10 is completed, when both the first camera 20 and the first sub-camera 31 need to be anti-shake, the second control unit 50 is configured as the master device and the first camera 20 is configured as the slave device. When only the first camera 20 needs to be anti-shake, the first camera 20 is configured as the master device. When only the first sub-camera 31 needs to be anti-shake, the first sub-camera 31 is configured as the master device.

[0064] In one embodiment, the second control unit 50 includes an intelligent sensor hub.

[0065] In this embodiment, since the smart sensor hub can connect and process data from various sensors, it can quickly process the jitter data detected by the inertial measurement unit to control the first sub-camera to perform anti-shake. By controlling the first sub-camera to perform anti-shake through the smart sensor hub, the second lens can move in a timely and accurate manner to perform displacement compensation, thereby improving the anti-shake effect of the camera module. At the same time, since the smart sensor hub can be a device in an electronic device, there is no need to add additional devices, thereby reducing the complexity of the electronic device structure.

[0066] Exemplarily, the third terminal of the smart sensor hub is electrically connected to the third terminal of the inertial measurement unit 10 .

[0067] For example, the first camera 20 may be a camera that performs anti-shake through an optical image stabilization (OIS) function. The first sub-camera 31 may be a camera that performs anti-shake through an optical image stabilization function of an application to sensor hub (AP).

[0068] In one embodiment, the first camera 20 includes a telephoto camera.

[0069] In this embodiment, since the focal length of the telephoto camera is relatively long, a large displacement will occur in the collected image under a slight shake of the electronic device. By performing anti-shake on the telephoto camera, the difficulty of picture shooting can be reduced, thereby improving the shooting effect.

[0070] In one embodiment, the first camera 20 includes a main camera.

[0071] In this embodiment, due to the slight shaking of the electronic device, the image captured by the main camera will have a large displacement. By performing anti-shake on the main camera, the difficulty of picture shooting can be reduced, thereby improving the shooting effect.

[0072] In one embodiment, the first sub-camera 31 includes a telephoto camera.

[0073] In this embodiment, since the focal length of the telephoto camera is relatively long, a large displacement will occur in the collected image under a slight shake of the electronic device. By performing anti-shake on the telephoto camera, the difficulty of picture shooting can be reduced, thereby improving the shooting effect.

[0074] In one embodiment, the first sub-camera 31 includes a main camera.

[0075] In this embodiment, due to the slight shaking of the electronic device, the image captured by the main camera will have a large displacement. By performing anti-shake on the main camera, the difficulty of picture shooting can be reduced, thereby improving the shooting effect.

[0076] In one embodiment, the second sub-camera 32 includes an ultra-wide-angle camera.

[0077] In this embodiment, due to the wide viewing angle of the ultra-wide-angle camera, the captured image will not undergo a large displacement under slight shaking of the electronic device. By not performing anti-shake on the ultra-wide-angle camera, the complexity of the second sub-camera structure can be reduced, and the cost of the camera module can be reduced.

[0078] In one embodiment, the second sub-camera 32 includes a short-focus camera.

[0079] In this embodiment, since the focal length of the short-focus camera is short, the captured image will not have a large displacement under slight shaking of the electronic device. By not performing anti-shake on the short-focus camera, the complexity of the second sub-camera structure can be reduced, and the cost of the camera module can be reduced.

[0080] In one embodiment, the inertial measurement unit 10 includes a gyroscope and an accelerometer.

[0081] In this embodiment, since the gyroscope can measure the angular velocity of the electronic device and the accelerometer can measure the acceleration of the electronic device, the displacement amount and the corresponding direction of the electronic device shaking can be determined by combining the acceleration and the angular velocity. By combining the gyroscope and the accelerometer to determine the displacement amount and the corresponding direction of the electronic device shaking, the lens movement can be accurately controlled to perform displacement compensation, thereby improving the anti-shake effect of the camera module.

[0082] An exemplary embodiment of the present disclosure provides a camera module, such as Figure 6As shown, the camera module includes an inertial measurement unit 10, a first camera 20, a first sub-camera 31, a second sub-camera 32 and an intelligent sensor hub 40. Among them, the first camera 20 includes a first control unit 21, a first drive circuit 22, a first motor 23 and a first lens 24. The first sub-camera 31 includes a second drive circuit 311, a second motor 312 and a second lens 313. The first end of the inertial measurement unit 10 is used to be electrically connected to the first power supply VDD1, the second end of the inertial measurement unit 10 is electrically connected to the first end of the first control unit 21 and the first end of the intelligent sensor hub 40 through the first communication bus, and the third end of the inertial measurement unit 10 is electrically connected to the third end of the intelligent sensor hub 40 through the second communication bus. The second end of the intelligent sensor hub 40 is electrically connected to the first end of the second drive circuit 311 through the third communication bus. The second end of the first control unit 21 is electrically connected to the first end of the first drive circuit 22. The second end of the first drive circuit 22 is electrically connected to the first end of the first motor 23. The second end of the first motor 23 is connected to the first lens 24. The second end of the second driving circuit 311 is electrically connected to the first end of the second motor 312. The second end of the second motor 312 is connected to the second lens 313. The power supply end of the first camera 20 is used to be electrically connected to the second power supply VDD2. The power supply end of the first sub-camera 31 and the power supply end of the second sub-camera 32 are both used to be electrically connected to the third power supply VDD3.

[0083] After the electronic device is turned on, the first power supply VDD1 supplies power to the inertial measurement unit 10, and the second power supply VDD2 supplies power to the first camera 20, and the electronic device can reliably identify the jitter data detected by the inertial measurement unit 10. After the second power supply VDD2 supplies power to the first camera 20 for a certain period of time, the electronic device can reliably identify the jitter data detected by the inertial measurement unit 10, and the second power supply VDD2 stops supplying power to the first camera 20 to reduce the power consumption of the camera module.

[0084] When the user is ready to shoot, the user selects a shooting mode in the electronic device. When the camera corresponding to the shooting mode is the first camera 20, the first power supply VDD1 supplies power to the inertial measurement unit 10, and the second power supply VDD2 supplies power to the first camera 20. The inertial measurement unit 10 detects the jitter data of the electronic device and transmits the jitter data to the first control unit 21 of the first camera 20. The first control unit 21 calculates the displacement that needs to be compensated for the first lens 24 based on the jitter data and transmits the corresponding signal to the first drive circuit 22. The first drive circuit 22 controls the first motor 23 to drive the first lens 24 to move according to the signal corresponding to the displacement transmitted by the first control unit 21. Since the third power supply VDD3 does not supply power to the second camera 30, the second camera 30 does not generate additional power consumption, thereby reducing the power consumption of the camera module.

[0085] When the user is ready to shoot, the user selects a shooting mode in the electronic device. When the camera corresponding to the shooting mode is the first sub-camera 31, the first power supply VDD1 supplies power to the inertial measurement unit 10, and the third power supply VDD3 supplies power to the second camera 30. The inertial measurement unit 10 detects the jitter data of the electronic device and transmits the jitter data to the smart sensor hub 40. The smart sensor hub 40 calculates the displacement that needs to be compensated for the second lens 313 based on the jitter data and transmits the corresponding signal to the second drive circuit 311. The second drive circuit 311 controls the second motor 312 to drive the second lens 313 to move according to the signal corresponding to the displacement transmitted by the smart sensor hub 40. Since the second power supply VDD2 does not supply power to the first camera 20, the first camera 20 does not generate additional power consumption, thereby reducing the power consumption of the camera module.

[0086] When the user is ready to shoot, the user selects a shooting mode in the electronic device. When the cameras corresponding to the shooting mode are the first camera 20 and the first sub-camera 31, the first power supply VDD1 supplies power to the inertial measurement unit 10, the second power supply VDD2 supplies power to the first camera 20, and the third power supply VDD3 supplies power to the second camera 30. The inertial measurement unit 10 detects the jitter data of the electronic device and transmits the jitter data to the smart sensor hub 40. The smart sensor hub 40 calculates the displacement that needs to be compensated for the second lens 313 based on the jitter data and transmits the corresponding signal to the second drive circuit 311. The second drive circuit 311 controls the second motor 312 to drive the second lens 313 to move according to the signal corresponding to the displacement transmitted by the smart sensor hub 40. At the same time, the first camera 20 acquires the jitter data by monitoring the jitter data transmitted from the inertial measurement unit 10 to the smart sensor hub 40 and transmits the jitter data to the first control unit 21 of the first camera 20. The first control unit 21 calculates the displacement that needs to be compensated for the first lens 24 based on the jitter data and transmits the corresponding signal to the first drive circuit 22. The first drive circuit 22 controls the first motor 23 to drive the first lens 24 to move according to the signal corresponding to the displacement transmitted by the first control unit 21. Since the second power supply VDD2 supplies power to the first camera 20 alone after the electronic device is turned on, the electronic device can reliably identify the jitter data detected by the inertial measurement unit 10 to improve the stability of the camera module.
