[0047] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0048] At present, more and more applications use OIS to achieve anti-shake. The OIS algorithm is more efficient, less costly, and more reliable. However, when using OIS, OIS commands and OIS-related power supplies must be controlled by the Sensor Hub, which imposes greater limitations on hardware design and occupies a larger internal space of the electronic device.

[0049] In view of the fact that the OIS HW and the camera in the camera module in the related art must be powered separately, resulting in a large occupied space, in order to reduce the space occupied by the OIS power supply, the embodiment of the present application provides a power supply module, Figure 1 A schematic diagram of the structure of an optional power supply module provided in an embodiment of the present application, such as Figure 1 As shown, the input end of the power supply module 100 is connected to the application processor 101, and the output end of the power supply module 100 is respectively connected to the power supply port 1021 of the optical image stabilization module of the camera module 102 and the power supply port 1022 of the camera of the camera module 102; wherein, the power supply module 100 is used for:

[0050] Based on the signal received at the input end, an enable signal of the power supply module 100 is acquired, and the power supply voltage of the power supply module 100 is converted according to the enable signal to obtain the power supply voltage.

[0051] The power supply module 100 is arranged between the application processor 101 and the camera module 102, and the camera module 102 includes an optical image stabilization module and a camera. In order to power the optical image stabilization module and the camera, the output end of the power supply module 100 is respectively connected to the power supply port 1021 of the optical image stabilization module and the power supply port 1022 of the camera, and the input end of the power supply module 100 is connected to the application processor 101.

[0052] The power supply module 100 can determine whether the enable signal of the power supply module 100 is obtained based on the signal received at the input end. When the enable signal of the power supply module 100 is obtained, the power supply module 100 converts the power supply voltage of the power supply module 100 to obtain the power supply voltage, wherein the power supply voltage is the voltage for supplying power to the optical image stabilization module and the camera.

[0053] When the disable enable signal of the power supply module 100 is obtained, the power supply module 100 does not work. At this time, the power supply module 100 does not supply power to the optical image stabilization module and the camera.

[0054] Among them, whether the above-mentioned power supply module 100 is enabled is determined based on the output of the application processor 101 to the power supply module 100, that is, whether the enable signal of the power supply module 100 is obtained is determined by the signal received at the input end of the power supply module 100. Only when the enable signal is obtained, the power supply module 100 supplies power to the optical image stabilization module and the camera. When it is not enabled, the power supply module 100 does not supply power to the optical image stabilization module and the camera.

[0055] In order to achieve the conversion of the power supply voltage of the power supply module 100 , a direct current converter (DCDC converter, DCDC) may be used to achieve the conversion of the power supply voltage of the power supply module 100 .

[0056] In this way, the application processor 101 can control the power supply module 100 to supply power to the optical image stabilization module and the camera, thereby enabling the optical image stabilization module and the camera to share a power supply, thereby reducing the space occupied by the OIS power supply.

[0057] Further, in order to obtain an enable signal of the power supply module 100 through a signal received at the input end to supply power to the optical image stabilization module and the camera, in an optional embodiment, the power supply module 100 is used to:

[0058] When the application processor 101 is started, the input terminal is left floating, an enable signal is obtained through the power supply of the power supply module 100, the power supply module 100 is enabled, and the power supply voltage of the power supply module 100 is converted to obtain a power supply voltage;

[0059] When the application processor 101 is started, an enable signal from the application processor 101 is received through the input terminal, the power supply module 100 is enabled, and the power supply voltage of the power supply module 100 is converted to obtain the power supply voltage.

[0060] It can be understood that here, it is divided into when the application processor 101 is started and after the application processor 101 is started. When the application processor 101 is started, at this time, the input end of the power supply module 100 connected to the application processor 101 is suspended. Under the action of the power supply module 100, the power supply module 100 receives an enable signal, thereby enabling the power supply module 100. Then, when the power supply module 100 is enabled, the power supply voltage of the power supply module 100 is converted to obtain the power supply voltage to supply power to the optical image stabilization module and the camera.

[0061] In addition, after the application processor 101 is started, at this time, the input end of the power supply module 100 connected to the application processor 101 is at a high level, and the signal received through the input end enables the power supply module 100 to receive an enable signal, thereby enabling the power supply module 100. Then, when the power supply module 100 is enabled, the power supply voltage of the power supply module 100 is converted to obtain the power supply voltage to supply power to the optical image stabilization module and the camera.

[0062] In this way, the power supply module 100 is enabled when and after the application processor 101 is started, and the power supply voltage of the power supply module 100 is converted to obtain the power supply voltage to supply power to the optical image stabilization module and the camera.

[0063] In order to realize the control of the power supply module 100, in an optional embodiment, the power supply module 100 is used to:

[0064] When the application processor 101 is started, a disable signal from the application processor 101 is received through the input terminal to disable the power supply module 100 .

[0065] It can be understood that when the application processor 01 is started, the application processor 101 controls whether the power supply module 100 is enabled through the signal received at the input end, wherein, when a disable enable signal is received from the application processor 101 through the input end, the power supply module 100 is disabled and the power supply module 100 does not work; wherein, the disable enable signal is a signal output when the application processor 101 receives a control instruction to shut down the power supply voltage.

[0066] That is to say, when there is no need to supply power to the optical image stabilization module and the camera, when the application processor 101 receives a control instruction to shut down the power supply voltage, it outputs a signal to the power supply module 100, so that the power supply module 100 receives a disable enable signal through the input end, so that the power supply module 100 does not work, thereby not supplying power to the optical image stabilization module and the camera.

[0067] In this way, the application processor controls whether the power supply module 100 supplies power to the optical image stabilization module and the camera.

[0068] Further, in order to control whether to enable the power supply module 100 through the input end, in an optional embodiment, the power supply module 100 includes: a power supply, a DC converter, a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor, a first capacitor, a second capacitor, a third capacitor, a fourth capacitor and a first inductor; wherein,

[0069] One end of the first resistor is connected to the application processor 101, the other end of the first resistor is respectively connected to one end of the second resistor, one end of the third resistor, one end of the first capacitor and the enable end of the DC converter, the other end of the second resistor is grounded, the other end of the third resistor is respectively connected to the power supply, one end of the second capacitor and the input end of the DC converter, the other end of the second capacitor is grounded, the switch end of the DC converter is connected to one end of the first inductor, the other end of the first inductor is respectively connected to the output end of the DC converter, one end of the fourth resistor, one end of the third capacitor, one end of the fourth capacitor, the power supply port of the optical image stabilization module and the power supply port of the camera, the other end of the third capacitor is grounded, the other end of the fourth capacitor is grounded, the other end of the fourth resistor is respectively connected to one end of the fifth resistor and the feedback end of the DC converter, and the other end of the fifth resistor is grounded.

[0070] It can be understood that the power supply module 100 is composed of the above-mentioned power supply, DC converter, first resistor, second resistor, third resistor, fourth resistor, fifth resistor, first capacitor, second capacitor, third capacitor, fourth capacitor and first inductor. The second resistor and the third resistor are voltage-dividing resistors for adjusting the enable voltage of the DC converter. The first resistor and the first capacitor form an RC loop, which plays a role of slow start. The second capacitor plays a role of voltage stabilization. The DC converter plays a role of voltage conversion. The third capacitor and the fourth capacitor are voltage-stabilizing capacitors for the supply voltage. The fourth resistor and the fifth resistor are voltage-dividing resistors. The first inductor is a component of the BUCK circuit.

[0071] In this way, the power supply module 100 is connected to the application processor 101, the optical image stabilization module and the camera to control the power supply of the optical image stabilization module and the camera.

[0072] Further, based on the above power supply module 100, in order to realize power supply to the optical image stabilization module and the camera, in an optional embodiment,

[0073] When the application processor 101 is started, one end of the first resistor is left floating, and the enable end of the DC converter obtains the enable signal through the power supply to enable the DC converter, and the DC converter converts the power supply voltage to obtain the supply voltage;

[0074] When the application processor 101 is started, one end of the first resistor receives a first control signal from the application processor 101, so that the enable end of the DC converter receives an enable signal to enable the DC converter, and the DC converter converts the power supply voltage to obtain a supply voltage.

[0075] It can be understood that when the application processor 101 is started, the input end is suspended, that is, one end of the first resistor is suspended. At this time, the power supply voltage of the power supply module 100 is divided by the first resistor and the second resistor. The voltage dividing resistor is the enable signal, which enables the DC converter. When the DC converter is enabled, it converts the power supply voltage to obtain the power supply voltage for the optical image stabilization module and the camera.

[0076] In addition, after the application processor 101 is started, at this time, the application processor 101 outputs a first control signal to the power supply module 100, for example, a high level, and one end of the first resistor receives the high level, so that the other end of the first resistor, that is, the enable end of the DC converter receives the enable signal, thereby enabling the DC converter. When the DC converter is enabled, the power supply voltage of the power supply module 100 is converted and processed, so as to obtain the power supply voltage for powering the optical image stabilization module and the camera.

[0077] In this way, based on the power supply module 100 , it is possible to power the optical image stabilization module and the camera when and after the application processor 101 is started.

[0078] In order to control the power supply to the optical image stabilization module and the camera, in an optional embodiment, when the application processor 101 is started, one end of the first resistor receives a second control signal from the application processor 101, so that the enable end of the DC converter receives a disable signal to disable the DC converter.

[0079] It can be understood that when the application processor 101 is started, in order to realize the control of power supply to the optical image stabilization module and the camera, the application processor 101 outputs a second control signal to the power supply module 100, for example, a low level, and one end of the first resistor receives the low level, so that the other end of the first resistor, that is, the enable end of the DC converter receives a disable signal, thereby disabling the DC converter, and the DC converter does not work, thereby not supplying power to the optical image stabilization module and the camera.

[0080] In this way, the power supply to the optical image stabilization module and the camera can be controlled.

[0081] An electronic device provided in an embodiment of the present application, Figure 2 A schematic diagram of an optional electronic device provided in an embodiment of the present application, such as Figure 2 As shown, the electronic device 200 includes the power supply module 100 as described in one or more of the above embodiments.

[0082] The power supply module described in one or more of the above embodiments is described below with examples.

[0083] Figure 3A schematic diagram of the structure of an example 1 of an optional power supply module provided in an embodiment of the present application, such as Figure 3 As shown, it includes: an application processor (AP), a smart sensor hub (Sensor Hub HW) (referred to as Sensor Hub for short), a gyroscope (GYRO HW) and a camera module; wherein the camera module includes an optical image stabilization module (OIS HW) and a camera (CAMERA).

[0084] In this example, the design that the power supply port (OISVDD) of the optical image stabilization module and the power supply port (AFVDD) of the camera must be separated in the related art is broken. In the related art, OISVDD needs to be directly connected to the Sensor Hub port, and the power supply must be used separately. Figure 3 The gyroscope transmits data to the Sensor Hub through the Serial Peripheral Interface (SPI), and then the Sensor Hub integrates the OIS algorithm internally and controls the OIS HW anti-shake through the Sensor Hub's Inter-Integrated Circuit (I2C) or SPI bus. The I2C command of the Sensor Hub must be sent after OISVDD is powered on, and the OIS HW in the camera module can receive the command.

[0085] In this example, the AP side is used for power supply. It is necessary to solve the timing problems of the AP core and the Sensor Hub during the startup process and the timing after power-on. This example solves this problem through hardware and software measures to achieve the purpose of sharing power supply for the AP side OIS HW and CAMERA automatic focus (Automatic Focus, AF).

[0086] The core of the hardware design of this example is to solve the timing problem of the AP kernel starting the probe device and the Sensor Hub starting the probe device during the boot process. Because it is uncertain which of the two systems will start working first, this example adopts the hardware boot-up and constant power-on solution during the startup phase.

[0087] Figure 4 A schematic diagram of the structure of an optional power supply module according to an embodiment of the present application is shown in FIG. Figure 4As shown, VPH_PWR is the battery voltage (equivalent to the power supply voltage of the above-mentioned power supply module), which is a fixed high level and is normally open. R7133 (equivalent to the above-mentioned third resistor) and R7135 (equivalent to the above-mentioned second resistor) are voltage-dividing resistors for adjusting the DCDC enable voltage. U7106 is DCDC for realizing voltage output regulation. C7137 (equivalent to the above-mentioned first capacitor) is for input voltage stabilization. R7131 (equivalent to the above-mentioned first resistor) and C7150 (equivalent to the above-mentioned second capacitor) are RC circuits for slow start. R7118 (equivalent to the above-mentioned fourth resistor) and R7117 (equivalent to the above-mentioned fifth resistor) are voltage-dividing resistors for controlling the output voltage. C7138 (equivalent to the above-mentioned fourth capacitor) and C7139 (equivalent to the above-mentioned fifth capacitor) are voltage-stabilizing capacitors for outputting OISVDD. L7102 (equivalent to the above-mentioned first inductor) is an inductor and is an important component of the BUCK circuit.

[0088] EN is the enable terminal of the AP segment with the default high level, that is, in the AP startup phase, EN is floating. At this time, the EN terminal voltage of DCDC is equal to VPH_PWR*R7133 / (R7133+R7135). This voltage is above 1.2V. Therefore, EN of DCDC is enabled high and OISVDD has output, that is, OISVDD is continuously high in the system startup phase.

[0089] When the AP is started, the enable EN CPIO of the AP defaults to 1.8V high, that is, at this time, the EN of the DCDC is enabled high, and the OISVDD is continuously output, that is, after the system is started, the OISVDD is continuously high.

[0090] When the system needs to turn off the power after startup, AP EN outputs a low level, that is, DCDC EN is enabled low, and OISVDD has no output.

[0091] It can be seen that by using hardware to keep OISVDD high during the startup phase of AP and Sensor Hub, the AP kernel can start the probe device and the Sensor Hub can start the probe device in a normal timing, so that the AP side can control OISVDD and complete the power sharing of AF and OISVDD. When both AP and Sensor Hub are started, the AP side opens a link to achieve communication between AP and Sensor Hub, thereby completing the power on and off control of the camera.

[0092] An embodiment of the present application provides a power supply module, wherein an input end of the power supply module is connected to an application processor, and an output end of the power supply module is respectively connected to a power supply port of an optical image stabilization module of a camera module and a power supply port of a camera of the camera module, and the power supply module is used to: obtain an enable signal of the power supply module based on a signal received at the input end, and convert a power supply voltage of the power supply module according to the enable signal to obtain a power supply voltage, wherein the power supply voltage is a voltage for supplying power to the optical image stabilization module and the camera; that is, in an embodiment of the present application, a power supply module connected to an application processor is used to obtain an enable signal of the power supply module based on a signal received at the input end of the power supply module connected to the application processor, thereby converting the power supply voltage of the power supply module to obtain a voltage for supplying power to the optical image stabilization module and the camera, thereby realizing power supply to the optical image stabilization module and the camera through the application processor, i.e., sharing a power supply, thereby reducing the space occupied by the OIS power supply.

[0094] In order to avoid the delay problem, based on the same inventive concept, the present application also provides a control method for a power supply module, which is applied to a control system of the power supply module.

[0096] Based on the above Figure 6 , Figure 7 A schematic diagram of the process interaction of an optional control method for a power supply module provided in an embodiment of the present application, such as Figure 7 As shown, the method may include:

[0097] S701: the application processor 101 sends a first interrupt signal to the smart sensor hub 61;

[0098] S702 : the smart sensor hub 61 sends a second interrupt signal to the application processor 101 .

[0099] Based on the above Figure 6 , the application processor 101 can communicate with the smart sensor hub 61. Then, in order to achieve anti-shake, the application processor 101 sends a first interrupt signal to the smart sensor hub 61, wherein the first interrupt signal is used to notify the application processor 101 whether to supply power to the optical image stabilization module and the camera. That is to say, the application processor 101 can inform the smart sensor hub 61 itself whether to supply power to the optical image stabilization module and the camera through the first interrupt signal.

[0100] In addition, the smart sensor hub 61 sends a second interrupt signal to the application processor 101, wherein the second interrupt signal is used to indicate whether the application processor 101 supplies power to the optical image stabilization module and the camera. That is, the smart sensor hub 61 can indicate through the second interrupt signal that the application processor 101 needs to supply power to the optical image stabilization module and the camera.

[0101] In actual applications, the first interrupt signal may be transmitted via the INT0 pin of the application processor 101 and the INT0 pin of the smart sensor hub 61 , and the second interrupt signal may be transmitted via the INT1 pin of the application processor 101 and the INT1 pin of the smart sensor hub 61 .

[0102] Among them, the above-mentioned first interrupt signal may include two sub-signals, one sub-signal is used to notify the application processor 101 to supply power to the optical image stabilization module and the camera, and the other sub-signal is used to notify the application processor 101 not to supply power to the optical image stabilization module and the camera; the above-mentioned second interrupt signal may include two sub-signals, one sub-signal is used to instruct the application processor 101 to supply power to the optical image stabilization module and the camera, and the other sub-signal is used to instruct the application processor 101 not to supply power to the optical image stabilization module and the camera.

[0103] In this way, the application processor 101 and the smart sensor hub 61 can control the power supply of the optical image stabilization module and the camera through the first interrupt signal and the second interrupt signal.

[0104] Furthermore, in order to prevent the optical image stabilization module and the camera from losing power, in an optional embodiment, the method further includes:

[0105] When the current first interrupt signal and the current second interrupt signal indicate that the application processor 101 needs to switch the power supply state to the optical image stabilization module and the camera, the application processor 101 supplies power to the optical image stabilization module and the camera, and sends the first sub-signal of the first interrupt signal to the smart sensor hub 61;

[0106] The smart sensor hub 61 sends the first sub-signal of the second interrupt signal to the application processor 101 .

[0107] It can be understood that when the current first interrupt signal and the current second interrupt signal indicate that the application processor 101 needs to switch the power supply state to the optical image stabilization module and the camera, for example, the first interrupt signal is 0 and the second interrupt signal is 1, it means that the smart sensor hub Sensor Hub 61 needs the application processor 101 to control the power supply module 100 to supply power to the optical image stabilization module and the camera, but in fact the application processor 101 does not supply power to the optical image stabilization module. At this time, the application processor 101 needs to switch the power supply state to the optical image stabilization module and the camera.

[0108] Alternatively, the first interrupt signal is 1 and the second interrupt signal is 0, indicating that the smart sensor hub 61 does not need the application processor 101 to control the power supply module 100 to supply power to the optical image stabilization module and the camera, but in fact the application processor 101 supplies power to the optical image stabilization module. At this time, the application processor 101 needs to switch the power supply state to the optical image stabilization module and the camera.

[0109] When the application processor 101 needs to switch the power supply state to the optical image stabilization module and the camera, in order to prevent power failure, that is, the first interrupt signal is 0 and the second interrupt signal is also 0, the application processor 101 can send the first sub-signal of the first interrupt signal to the smart sensor hub 61, wherein the first sub-signal of the first interrupt signal is used to notify the application processor 101 to supply power to the optical image stabilization module and the camera; for example, the first sub-signal of the first interrupt signal is 1; the smart sensor hub 61 sends the first sub-signal of the second interrupt signal to the application processor 101, wherein the first sub-signal of the second interrupt signal is used to instruct the application processor 101 to supply power to the optical image stabilization module and the camera; for example, the first sub-signal of the second interrupt signal is 1.

[0110] In this way, power failure is avoided when the first sub-signal of the first interrupt signal and the first sub-signal of the second interrupt signal are converted into other states.

[0111] The control method of the power supply module described in one or more of the above embodiments is described below with examples.

[0112] The software design of this example mainly applies the link design of the processor 101 and the intelligent sensor hub 61 and optimizes the real-time performance of system transmission. Figure 8 A schematic diagram of an example of a control system of an optional power supply module provided in an embodiment of the present application is shown in FIG. Figure 8 As shown, the software block diagram of OIS power sharing is as follows:

[0113] This example establishes a separate hardware path through the interrupt signal GPIO of the application processor 101 and the smart sensor hub 61. The application processor 101 transmits an interrupt signal 0 or 1 to the smart sensor hub 61 through INT0; the smart sensor hub 61 transmits 0 or 1 to the application processor 101 through INT1; by default, INT0 is low and INT1 is high, and the information status has four symbol information: [0, 0], [0, 1], [1, 0], [1, 1].

[0114] Fig. 9 An example of an optional information state switching provided in an embodiment of the present application Figure 1 ,like Fig. 9 Shown is the software switching scheme, with a total of 12 changes, including: [0, 0] to [0, 1], [0, 0] to [1, 1], [0, 0] to [1, 0]; [1, 0] to [0, 1], [1, 0] to [1, 1], [1, 0] to [0, 0]; [0, 1] to [0, 0], [0, 1] to [1, 1], [0, 0] to [1, 0]; [1, 1] to [0, 1], [1, 1] to [0, 0], [1, 1] to [1, 0].

[0115] Depend on Fig. 9 It can be seen that when switching from [0, 0] and [1, 1] to other states, the receiving state is fixed and there will be no timing misjudgment problem. However, when switching from [0, 1] --- [1, 0], it should continue to be high. However, if the switching process appears [0, 1] --- [0, 0] --- [1, 0] state, it will cause power failure in the middle, resulting in functional abnormalities.

[0116] To prevent power failure, Fig.10 An example of an optional information state switching provided in an embodiment of the present application Figure 2 ,like Fig.10 As shown, in this example, no matter what the initial state is during the switching process, the transition is performed through [1, 1] to solve the power-off problem during the switching process: when switching is required, the state before the switching is first converted to [1, 1], which is called the transition state, and then the state after the switching is obtained by switching from the transition state.

[0117] That is to say, this example proposes a power sharing solution for the application processor 101 and the smart sensor hub 61, which saves product costs; and proposes a hardware path for the application processor 101 and the smart sensor hub 61, which improves the overall performance of the mobile phone.

[0118] This example proposes a solution to share OIS power and AF power at the AP end, which solves the problem of timing asynchrony during the boot process through hardware; proposes a hardware path between AP and Sensor Hub, which is triggered by an interrupt signal and is more efficient; and proposes a software transition solution to solve the intermediate unconfirmed state and improve performance stability.

[0119] It should be pointed out that this example is not only applicable to the mobile phone industry, but also to all camera OIS products; this example proposes a software optimization solution, which can not only be applied to OIS power sharing, but also to effect debugging and driver performance optimization.
