Description

Technical Field

[0001] This application belongs to the field of camera modules, specifically relating to a camera module control method, control device, electronic device, and readable storage medium for an electronic device. Background Technology

[0002] With the development of technology, electronic devices are becoming increasingly widely used. Typically, electronic devices include a camera system, which comprises a camera module, a controller, and a display unit. The controller is electrically connected to the camera module and uses I2C control lines to configure registers to control the camera module in acquiring image information. The image information is then transmitted to the controller via the MIPI bus. The controller processes the received image information and displays it on the display unit for the user to preview. However, electronic devices often contain radio frequency (RF) communication modules, which may interfere with the camera module, indicating a relatively low spatial isolation between them. Summary of the Invention

[0003] The purpose of this application is to provide a method, device, electronic device and readable storage medium for controlling a camera module of an electronic device, at least to solve the problem of poor imaging effect of the camera module.

[0004] In a first aspect, embodiments of this application provide a camera module control method for an electronic device, the camera module control method comprising:

[0005] Obtain usage information of the electronic device, including the operating frequency band of the electronic device, the transmission power of the electronic device, and the serial number of the radio frequency antenna of the electronic device;

[0006] Based on the usage information, determine the operating status of the electronic device;

[0007] When the electronic device is operating in a first preset state, the camera module is configured in a first operating mode; when the electronic device is operating in a second preset state, the camera module is configured in a second operating mode. The first operating mode is different from the second operating mode. The first preset state includes the electronic device operating in a non-risk frequency band, or the influence of the electronic device's antenna module on the camera module being less than a set value. The second preset state includes the electronic device operating in a risk frequency band, and the electronic device's transmission frequency being greater than a preset threshold; or, the electronic device operating in a preset scenario.

[0008] Secondly, embodiments of this application provide a camera module control device for an electronic device, the control device comprising:

[0009] The acquisition module is used to acquire usage information of the electronic device, including the operating frequency band of the electronic device, the transmission power of the electronic device, and the number of the radio frequency antenna of the electronic device.

[0010] A determining module is used to determine the operating status of the electronic device based on the usage information;

[0011] A configuration module is used to configure the camera module to a first working mode when the electronic device is operating in a first preset state; and to configure the camera module to a second working mode when the electronic device is operating in a second preset state. The first working mode is different from the second working mode. The first preset state includes the electronic device operating in a non-risk frequency band, or the influence value of the antenna module of the electronic device on the camera module of the electronic device being less than a set value. The second preset state includes the electronic device operating in a risk frequency band, and the transmission frequency of the electronic device being greater than a preset threshold; or the electronic device operating in a preset scenario.

[0012] Thirdly, embodiments of this application provide an electronic device including a processor and a memory, wherein the memory stores programs or instructions executable on the processor, and the programs or instructions, when executed by the processor, implement the steps of the method described in the first aspect.

[0013] Fourthly, embodiments of this application provide a readable storage medium on which a program or instructions are stored, which, when executed by a processor, implement the steps of the method described in the first aspect.

[0015] In a sixth aspect, embodiments of this application provide a computer program product stored in a storage medium, which is executed by at least one processor to implement the method described in the first aspect.

[0016] In this embodiment, usage information of the electronic device is obtained, including the device's operating frequency band, transmission power, and radio frequency antenna number. Based on this usage information, the operating state of the electronic device is determined. When the electronic device is in a first preset state, the camera module is configured in a first operating mode; when the electronic device is in a second preset state, the camera module is configured in a second operating mode. The first and second operating modes are different. In other words, in this embodiment, the camera module is configured in different operating modes depending on the operating state of the electronic device, minimizing interference to the camera module and thus improving its imaging performance.

[0022] The terms "first" and "second" in the specification and claims of this application may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise stated, "multiple" means two or more. Furthermore, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0023] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] Reference Figure 1 This document illustrates a flowchart of a camera module control method for an electronic device according to an embodiment of this application. In this embodiment, the electronic camera module control method is applied to an electronic device that supports both D-PHY and C-PHY modes. In D-PHY, D stands for Roman numeral 500, and PHY stands for channel. D-PHY provides source synchronization for DSI (Display Serial Interface) and CSI (Camera Serial Interface), enabling high-speed, low-power physical layer implementation. In C-PHY, C stands for Channel Limited, and it is a physical layer implementation based on three-phase symbol encoding technology, primarily used for display serial interfaces and camera serial interfaces.

[0025] like Figure 1 As shown, the camera module control method includes:

[0026] Step 101: Obtain the usage information of the electronic device, including the operating frequency band of the electronic device, the transmission power of the electronic device, and the serial number of the radio frequency antenna of the electronic device.

[0027] Once the electronic device is powered on, it can operate normally. During this operation, the radio frequency (RF) module within the device functions, enabling communication. The RF module includes an RF antenna, feedhorn, and transceiver. Furthermore, while the RF module is running, its transmission frequency (i.e., the electronic device's transmission power), the operating frequency band for communication, and the antenna number can be obtained.

[0028] It should be noted that electronic devices have multiple radio frequency antennas, which can be pre-numbered. When the electronic device is communicating, it is possible to determine which specific radio frequency antenna is transmitting or receiving signals, thus identifying the antenna number.

[0029] Step 102: Determine the operating status of the electronic device based on the usage information.

[0030] After obtaining the usage information of the electronic device, its operating status can be determined. This usage information includes the electronic device's operating frequency band, transmission power, and radio frequency antenna number. Therefore, obtaining this information is equivalent to determining the current operating frequency band and power of the electronic device, thus enabling the determination of its operating status.

[0031] Step 103: When the electronic device is operating in a first preset state, configure the camera module to a first operating mode; when the electronic device is operating in a second preset state, configure the camera module to a second operating mode. The first and second operating modes are different. The first preset state includes situations where the electronic device operates in a non-risk frequency band, or the influence of the electronic device's antenna module on the camera module is less than a set value. The second preset state includes situations where the electronic device operates in a risky frequency band, and the electronic device's transmission frequency is greater than a preset threshold; or, the electronic device is operating under a preset scenario.

[0032] When the electronic device is in the first preset state, it indicates that the operating frequency band of the electronic device is a non-risk frequency band. When the electronic device is working, the frequency band in which the radio frequency antenna transmits radio frequency signals is the operating frequency band of the electronic device. When the radio frequency band is within a certain frequency range, the radio frequency antenna has a significant impact on the camera module, thus the radio frequency band is a risky frequency band. When the radio frequency band is in another radio frequency range, the radio frequency antenna has no impact on the camera module or has a small impact, thus the radio frequency band is a non-risk frequency band.

[0033] In addition, in the embodiments of this application, the first working mode can be the mode in which the camera module of the electronic device operates in C-PHY mode, and the second working mode can be the mode in which the camera module operates in D-PHY mode.

[0034] Furthermore, in this embodiment, the preset scenario can be a scenario where the electronic device is making a video call, a scenario where the electronic device is uploading data, or a scenario where the electronic device is moving at high speed. For example, a user carrying an electronic device on a high-speed train, where the electronic device is moving at high speed relative to the ground, is an example of a scenario where the electronic device is moving at high speed.

[0035] As can be seen from the above, when the electronic device is in the first preset state, configuring the camera module in C-PHY mode can save power consumption and maximize the imaging function of the camera module; when the electronic device is in the second preset state, configuring the camera in D-PHY mode can improve the anti-interference capability of the camera module.

[0036] In addition, in some implementations, the electronic device includes multiple radio frequency antennas, and the camera module of the electronic device includes multiple cameras. Before step 101, the camera module control method may further include: determining the isolation degree between the target radio frequency antenna and each camera when operating in different radio frequency bands, wherein the target radio frequency antenna is any one of the multiple radio frequency antennas; determining the risk frequency band of each radio frequency antenna according to the isolation degree, and forming a correspondence table between radio frequency antennas and cameras, wherein the correspondence table has the number of the radio frequency antenna, the number of the camera, and the risk level, wherein when the risk level is greater than a preset level, the radio frequency band of the radio frequency antenna is the risk frequency band.

[0037] In this context, the RF antenna, due to its transmitted signals, can interfere with the camera module. Furthermore, the RF antenna and the camera have a degree of isolation. Therefore, the isolation between the target RF antenna and each camera can be determined when the antenna operates in different RF bands. For example, multiple RF antennas can be designated as antenna A, antenna B, and antenna C, and multiple cameras can be designated as camera A, camera B, and camera C. Thus, when antenna A operates in different RF bands, the isolation between antenna A and cameras A, B, and C can be determined separately.

[0038] Once the isolation level is determined, the risk frequency band for each RF antenna can be identified, and then a table showing the correspondence between the RF antennas and the camera can be created.

[0039] For example, Table 1 shows the correspondence between radio frequency antennas and cameras.

[0040] Table 1

[0041]

[0042] As shown in Table 1, for camera 3, when antennas 3 and 4 are operating, the risk level is B. In this case, for camera 3, if antenna 3 operates in the radio frequency band BAND3, then the BAND3 band of antenna 3 is a risky band for camera 3; similarly, if antenna 4 operates in the radio frequency band BAND3, then the BAND4 band of antenna 5 is a risky band for camera 4; and if antenna 6 operates in the radio frequency band BAND4, then the BAND4 band of antenna 6 is a risky band for camera 4. The risk levels are ranked A, B, and C, where A represents the lowest risk, B represents a relatively high risk, and C represents an even higher risk.

[0043] In addition, in some implementations, the camera module control method may also include: when the electronic device is connected to the network, recording the operating frequency band, transmission power, and radio frequency antenna number of the electronic device in a preset table; determining whether the operating frequency band of the electronic device is a risky frequency band according to the corresponding relationship table; if the operating frequency band of the electronic device is a risky frequency band, recording the risky frequency band and the radio frequency antenna number corresponding to the risky frequency band in the preset table, and determining whether the transmission power is greater than a preset power threshold; if the transmission power is greater than the preset power threshold, recording it in the preset table.

[0044] After establishing the correspondence between the RF antenna and the camera, when the electronic device connects to the network, it will transmit signals. At this time, the operating frequency band, transmission power, and RF antenna number of the electronic device can be recorded in a preset table. Furthermore, the table can be used to check whether the current operating frequency band of the electronic device is a preset risk band. That is, after determining the current operating frequency band of the electronic device, its location can be found in the RF antenna-camera correspondence table, thereby determining whether the current operating frequency band of the electronic device is a risk band.

[0045] If the operating frequency band of the electronic device is a risky frequency band, the risky frequency band and the corresponding radio frequency antenna number are recorded in a preset table, which is equivalent to updating the preset table. Furthermore, it can be determined whether the current transmission power of the electronic device exceeds a preset power threshold. If the transmission power exceeds the preset power threshold, the record is continued in the preset table. That is, in this embodiment, the preset table can be updated in real time during the operation of the electronic device, making it easier to determine the operating status of the electronic device based on the preset table later.

[0046] For example, Table 2 is a sample of a preset table.

[0047] Table 2

[0048]

[0049]

[0050] Among them, the power counter R2 is the power counter of the electronic device. The larger the value recorded by the power counter, the more times the radio frequency band has been operated at high power. The register stores the number of times the electronic device has used the risky frequency band more than the threshold in the past. The larger the value recorded by the register, the greater the probability that the electronic device has switched to the risky frequency band.

[0051] In addition, in some implementations, the preset table contains a risk frequency band count item and a risk frequency band total count item. If the operating frequency band of the electronic device is a risk frequency band, the implementation method for recording the risk frequency band and the corresponding RF antenna number in the preset table can be as follows: determine whether the preset table contains the frequency band information corresponding to the risk frequency band and the RF antenna number corresponding to the risk frequency band; if the preset table contains the frequency band information corresponding to the risk frequency band and the RF antenna number corresponding to the risk frequency band, update the count value corresponding to the risk frequency band count item; if the count value is greater than the pre-designed value, update the value corresponding to the risk frequency band total count item.

[0052] Specifically, if the preset table contains information about the frequency band corresponding to the risky frequency band and the corresponding RF antenna number, the value in the "Risk Frequency Band Count" field is updated, thus updating the corresponding count value. For example, if the initial value of the "Risk Frequency Band Count" field is 2, and the preset table contains information about the frequency band and the corresponding RF antenna number, the value of the "Risk Frequency Band Count" field is updated to 3. Furthermore, if the count value is greater than the pre-designed value, the value corresponding to the "Total Risk Frequency Band Count" field is updated. For example, if the initial value of the "Total Risk Frequency Band Count" field is 0, and the count value is greater than the pre-designed value, the value of the "Total Risk Frequency Band Count" field is updated from 0 to 1.

[0053] As shown in Table 2, the total number of risk band counts is the item containing the register, and the number of risk band counts is the item containing the power counter.

[0054] In addition, in some implementations, step 102 can be implemented as follows: determine whether the operating frequency band of the electronic device is a risky frequency band; if the operating frequency band of the electronic device is a non-risky frequency band, determine that the operating state of the electronic device is a first preset state; if the operating frequency band of the electronic device is a risky frequency band, determine whether the transmission power of the electronic device is greater than a preset power threshold; if the transmission power is greater than the preset power threshold, determine that the electronic device is in a second preset state.

[0055] In the operation of electronic devices, the impact of radio frequency antennas on cameras includes two aspects: first, the radio frequency band of the radio frequency antenna, and second, the transmission power of the radio frequency antenna. Only when the radio frequency band of the radio frequency antenna is a risky band and the transmission power is greater than a preset power threshold will the radio frequency antenna have a significant impact on the camera. Therefore, in this embodiment, when the operating frequency band of the electronic device is a risky band, it is determined whether the transmission power of the electronic device is greater than the preset power threshold. If the transmission power is greater than the preset power threshold, it is determined that the electronic device is in a second preset state, thereby ensuring accurate determination of the operating state of the electronic device.

[0056] In addition, in some implementations, the camera module control method may also include: detecting network information of the electronic device's connection to the network at preset intervals to determine the electronic device's operating frequency band, transmission power, and the number of the radio frequency antenna.

[0057] During the operation of the electronic device, network information can be detected at preset intervals to determine the device's operating frequency band, transmission power, and RF antenna number. Different operating frequency bands, transmission power, and RF antenna numbers result in different network information for the electronic device. For example, the network information might be wireless network information, 4G network information, or 5G network information.

[0058] Alternatively, in some implementations, the usage information of electronic devices can be obtained by retrieving it from a preset table. This preset table contains the usage information of the electronic devices, allowing the information to be retrieved from the table.

[0059] Additionally, in the embodiments of this application, such as Figure 2 As shown, the electronic device may include a controller, a camera module, and a power supply module. The controller and the camera module can be connected via an interface, specifically, as shown... Figure 2 The pins of the CSI_RX and CSI_TX interfaces can be connected using different connecting wires. When all the pins of these two interfaces are connected, the camera module is in D-PHY mode. That is, when all ten pins of these two interfaces are connected, the camera module is in D-PHY mode. When nine out of the ten pins of these two interfaces are connected, the camera module is in C-PHY mode.

[0060] In this embodiment, usage information of the electronic device is obtained, including the device's operating frequency band, transmission power, and radio frequency antenna number. Based on this usage information, the operating state of the electronic device is determined. When the electronic device is in a first preset state, the camera module is configured in a first operating mode; when the electronic device is in a second preset state, the camera module is configured in a second operating mode. The first and second operating modes are different. In other words, in this embodiment, the camera module is configured in different operating modes depending on the operating state of the electronic device, minimizing interference to the camera module and thus improving its imaging performance.

[0061] The camera module control method for electronic devices provided in this application can be executed by a camera module control device for electronic devices.
