All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

For convenience of description, in the present application, the above-mentioned devices are collectively referred to as electronic devices.

The following describes embodiments of the present invention in detail.

Referring to fig. 1, fig. 1 is a system architecture diagram of a camera focus correction method according to an embodiment of the present invention, as shown in fig. 1, the system architecture includes a camera module 100, a processor 110, the camera module includes a camera 120, a motor control chip 130, and a motor 140, and the motor control chip may include an Inter-Integrated Circuit (I2C) interface 131, a location register 132, and a logic control Circuit 133. The processor 110 may control the camera module 100 to enable the camera 120 to complete a focusing operation, where the camera 120 includes but is not limited to a camera lens.

The processor 110 and the motor control chip 130 are connected through an I2C interface 131, the I2C interface 131 forms a Serial bus by a Data line (Serial Data, SDA) and a control line (Serial Clock L ine, SC L), specifically, the processor 110 can directly send Data to a position register 132 in the motor control chip 130 through the control line SC L and the Data line SDA, or read Data in the position register 132, the Data includes a relevant instruction for controlling the operation of the motor control chip, the relevant instruction can be a power-on reset instruction, an overcurrent protection instruction, a lens shading correction instruction, and the like, the position register 132 is connected to a logic control circuit 133, and the logic control circuit 133 directly controls the magnitude of an output current to drive the motor 140.

Specifically, the processor 110 may be a Central Processing Unit (CPU) for controlling each part of the electronic device to complete work.

Specifically, the position register 132 may be a Digital to analog converter (DAC) for converting a Digital signal into an analog signal, wherein the DAC may convert a written binary Digital signal into an analog voltage signal. The number of bits of the binary digital signal is different, and the number of analog voltage signals that the digital-to-analog converter can convert is also different. In general, the more the number of bits of a binary digital signal, the more the number of analog voltage signals that can be converted, and the higher the focusing accuracy that can be provided. For example, for binary digital signals, if the DAC is a 10-Bit DAC, it can convert 1024 (2)¹⁰) Different analog voltage signals.

Specifically, the position register 132 receives a focusing parameter sent by the processor 110, where the focusing parameter may be a binary code, the position register 132 may temporarily store the binary code, convert the binary code into a corresponding voltage signal, and then send the voltage signal to the logic control circuit 133, the logic control circuit 133 generates a corresponding output current according to the voltage signal, and the output current drives the motor 140 to operate, so that the camera 120 moves to a focusing position, and completes a focusing operation.

Referring to fig. 2 based on the system architecture of fig. 1, fig. 2 is a schematic flowchart of a camera focus correction method according to an embodiment of the present invention, where the method includes the following steps:

step 201, when the camera takes a picture, obtaining a focusing parameter, and writing the focusing parameter into a position register of the motor control chip;

the focusing parameter in the present application may be a binary code, the focusing parameter is generated based on environment information during shooting, optionally, the environment information during shooting may include a distance between the camera and a shot object, the position register is configured to convert the focusing parameter into a voltage signal and send the voltage signal to the logic control circuit, and the position register may be a digital-to-analog converter DAC.

Specifically, the processor obtains a corresponding focusing parameter according to the environment information during shooting, and writes the focusing parameter into a position register in the motor control chip through a control line SC L and a data line SDA forming an I2C interface, where the position register may include, but is not limited to, a 10Bit DAC, an 8Bit DAC, etc., where a 10Bit equal-digit number merely indicates the number of different switchable focusing parameters, for example, 10Bit indicates that the position register can switch 1024 different focusing parameters, 8Bit indicates that the position register can switch 256 different focusing parameters, the position register is used to convert the written focusing parameter into a corresponding analog signal, and the analog signal may be a voltage signal.

When the camera shoots, the focusing parameters are obtained, and the focusing parameters are generated according to the environmental information during shooting, so that more accurate focusing parameters can be obtained. The use of a more digital-to-analog converter also allows for greater focusing accuracy.

Step 202, reading the data in the position register, and determining whether the data read from the position register is consistent with the focusing parameter. If yes, go to step 205, otherwise go to step 203.

If the static electricity interference exists in the position register, when the static electricity in the position register is accumulated to a certain degree, the data stored in the position register is abnormal, and the focusing operation cannot be accurately finished subsequently. Based on this, the present application may determine whether there is electrostatic interference in the position register by adding step 202 to detect whether there is an abnormality in the data stored in the position register.

The processor writes a focus parameter into the position register, reads the focus parameter data in the position register through the control line SC L and the data line SDA forming the I2C interface, and determines whether the read data and the written focus parameter are the same, that is, whether the binary code is the same.

Specifically, when writing the focus parameter into the position register, the processor may temporarily store the focus parameter in the processor, compare the focus parameter with the read data in the position register, determine whether the binary codes of the two binary codes are the same, and detect whether the data stored in the position register is abnormal.

Step 203, performing a power-off reset operation on the motor control chip.

The processor controls the motor control chip to power off and reset firstly, and is used for clearing data in the position register and clearing electrostatic interference. The static electricity may interfere with the writing process in step 201, so that the data in the position register is inconsistent with the written focusing parameters, and focusing cannot be performed during shooting.

The location register is a Random Access Memory (RAM). The data stored on the RAM can disappear automatically after the power is cut off, and the RAM is sensitive to static electricity and is easy to be interfered.

Step 204, rewriting the focusing parameter into the position register.

Specifically, because the step 203 has already performed the power-off reset operation, the electrostatic interference in the position register has been eliminated, and the data stored in the position register returns to normal, the step 202 does not need to be repeatedly performed, and because the time interval between the step 203 and the step 204 is short, the static electricity will not be accumulated to the extent that the static electricity affects the position register in a short time, the focusing parameter has already been corrected and no error will be generated in a short time, thereby ensuring the accuracy of the subsequent focusing operation.

Step 205, controlling the motor to complete focusing.

Wherein, the motor is controlled by a motor control chip.

Specifically, the position register converts the correct focusing parameters into corresponding voltage signals and sends the voltage signals to the logic control circuit, the logic control circuit outputs corresponding output currents according to the voltage signals, the output currents drive the motor to work, and the motor controls the lens to move to a focusing position to complete focusing.

Referring to fig. 3, fig. 3 is a schematic flow chart of another camera focus correction method according to an embodiment of the present invention, fig. 3 is obtained by further optimizing on the basis of fig. 2, and the method flow shown in fig. 3 includes the following steps:

step 301, when the camera takes a picture, obtaining a focusing parameter, and writing the focusing parameter into a position register of the motor control chip.

Step 302, obtaining a time difference between a time of performing a power-off reset operation on the motor control chip and a current time.

The processor can record the time of the last power-off reset operation and store the time in the processor, and when a new shooting operation is executed, the time difference between the time of the power-off reset operation and the current time is obtained through calculation, and the time difference data is stored in the processor.

After power-off reset, a period of time is required for static electricity to be accumulated to a value which is enough to interfere the position register, whether the position register is subjected to the static electricity interference can be no longer detected within a period of time after the power-off reset operation in order to avoid complicated reading operation, whether the static electricity interference exists in the position register is determined by obtaining the time difference between the last time of the power-off reset operation and the current time, and repeated reading operation can be avoided. For scenes of continuous shooting (photographing or video recording), the focusing process can be simplified, so that accurate focusing is realized.

Step 303, obtaining the current humidity, and determining the target humidity range in which the current humidity falls.

The humidity information of the surrounding environment can be acquired through a humidity sensor (or a temperature and humidity sensor) on the electronic device, and the processor determines the corresponding humidity range according to the humidity information. The corresponding relation is that a target preset time corresponding to the target humidity range is determined according to the humidity, optionally, when the humidity is less than or equal to 45%, the target preset time is set to be thirty minutes, and when the humidity is greater than 45%, the target preset time is set to be sixty minutes.

And step 304, determining a target preset time length corresponding to the target humidity range according to the corresponding relation between the humidity range and the preset time length.

The generation of static has very big relation with humidity, is difficult to produce static under the environment that humidity is great, and just produces static very easily in drier environment, through acquireing humidity information, can set up different targets according to different environment and predetermine for a long time. Compared with the method for presetting the time length by adopting the fixed target, the method and the device for presetting the time length can adapt to the environments with different humidity, on one hand, the longer target preset time length can be set in the environment with higher humidity, the repeated reading operation is avoided, and the focusing process is simplified. On the other hand, a shorter target preset time can be set in an environment with lower humidity, and the focusing accuracy is improved.

Step 305, judging whether the time difference between the time of once power-off reset operation on the motor control chip and the current time is greater than a target preset time length; if yes, go to step 306, otherwise go to step 309.

The preset target duration may be a preset duration that elapses after the last power-off reset operation is performed in the processor, and the preset target duration may be set by a duration that static electricity is accumulated after the power-off reset operation to a duration that may affect the threshold requirement of step 201.

Specifically, the time difference data is compared with a target preset time length, and whether the time length of the time difference is greater than the target preset time length is judged.

Whether the operation of reading the data in the position register should be performed again can be clearly judged by comparing with a target preset time period, which can be set according to the degree of difficulty of generation of static electricity in the surrounding environment.

The target preset time length can be preset and stored in a nonvolatile memory of the processor. For example, the target preset time period may be set to 30 minutes.

Wherein, step 303 and step 304 are optional steps.

Step 306, reading the data in the position register, and determining whether the data read from the position register is consistent with the focusing parameter. If yes, go to step 309, otherwise go to step 307.

Step 307, performing a power-off reset operation on the motor control chip.

Step 308, rewriting the focusing parameter into the position register.

Step 309, controlling the motor to complete focusing.

301, 306 to 309 can refer to the corresponding description of the steps 201 to 205 shown in fig. 2, and is not described herein again.
