Fig. 1 is a flowchart illustrating a photographing method according to an exemplary embodiment, where the method illustrated in fig. 1 may be applied to an electronic device, and the method illustrated in fig. 1 may include:

in step 101, during shooting, a refresh frequency currently used by a screen is acquired.

The electronic equipment is provided with a screen, and the screen is refreshed according to a certain refreshing frequency in the using process of the electronic equipment.

Based on different screen structures and control methods, some screens can only be refreshed by using a fixed refresh frequency, and some screens can use a dynamically changeable refresh frequency.

In some embodiments, the screen is provided with configuration parameters that may directly include the refresh frequency of screen usage, or the configuration parameters may include information for determining the refresh frequency of screen usage. The electronic device may determine a refresh frequency of the screen according to the configuration parameters of the screen.

For example, before the electronic device leaves the factory, configuration parameters of the screen are set, the configuration parameters include a refresh frequency used by the screen, and after the electronic device leaves the factory, the screen is refreshed by using the refresh frequency included in the configuration parameters.

In some embodiments, the electronic device may determine the refresh frequency of the screen according to the actual usage data of the screen during the shooting process. And obtaining the current used refreshing frequency of the screen.

The actual usage data of the screen is used to determine the refresh frequency currently used by the screen. The actual usage data of the screen may directly include a refresh frequency currently used by the screen, or the actual usage data of the screen may include information for determining the refresh frequency currently used by the screen.

In some embodiments, the screen is provided with refresh modes, and the frequency acquisition mode used in different refresh modes is different, and the frequency acquisition mode defines the mode of acquiring the refresh frequency used by the screen.

Based on this, the refresh frequency currently used by the screen can be obtained by: the method comprises a first step of determining a refresh mode used by a screen, wherein the refresh mode comprises the following steps: refreshing according to a fixed refreshing frequency, or refreshing according to a dynamically changing refreshing frequency; and a second step of acquiring the refresh frequency according to a frequency acquisition mode of the refresh mode suitable for the screen.

For the first step, determining the refresh mode used by the screen can be understood as: the refresh mode currently used by the screen is determined.

There are various ways to determine the refresh mode used by the screen. For example, the configuration parameters of the screen include a refresh mode used by the screen, and the refresh mode used by the screen may be determined according to the configuration parameters of the screen.

For another example, the refresh frequency of the screen used within a period of time is recorded, the electronic device determines whether the refresh frequency of the screen used changes according to the record, if not, the refresh mode of the screen used is determined to be refreshing according to the fixed refresh frequency, and if so, the refresh mode of the screen used is determined to be refreshing according to the dynamically changing refresh frequency.

For the second step, for example, when the refresh mode used by the screen includes refreshing at a dynamically changing refresh frequency, the frequency acquisition manner suitable for the refresh mode may include: and determining the refreshing frequency of the screen according to the configuration parameters of the screen, or determining the refreshing frequency of the screen according to the actual use data of the screen.

For another example, when the refresh mode used by the screen includes refreshing according to the dynamically changing refresh frequency, the frequency acquisition mode suitable for the refresh mode may include: and determining the refreshing frequency of the screen according to the actual use data of the screen.

In some embodiments, the electronic device may perform an operation of acquiring a refresh frequency currently used by the screen when a preset condition is satisfied.

Examples are as follows: the case of the first example: and responding to the condition that the camera module outputs the image, and acquiring the refreshing frequency of the screen.

The camera module may include an image sensor, and an image may be output through the image sensor of the camera module.

The camera module can output images according to the image output frame rate. For example, satisfying the condition that the camera module outputs the image can be understood as: the condition that the camera module determines the image to be output according to the currently used image output frame rate is met.

In this example case, the electronic device obtains the refresh frequency currently used by the screen before outputting the image.

The case of the second example: and acquiring the refreshing frequency of the screen use in response to the condition of the time interval being met.

The electronic equipment sets a time interval condition, and the time interval condition defines that: the electronic device is adjacent to the interval time between two times of executing the refresh frequency acquisition operation.

After the electronic equipment executes the operation of acquiring the refresh frequency of the screen, if the interval time defined by the time interval condition passes, the electronic equipment executes the operation of acquiring the refresh frequency of the screen again.

The length of the interval time defined by the time interval condition can be set according to needs and experience, and the embodiment is not limited herein.

In this exemplary case, the electronic device performs an operation of acquiring the refresh frequency currently used by the screen at intervals.

Case of the third example: and responding to the condition that the frame number interval is met, and acquiring the refreshing frequency of the screen.

Frame number interval condition defines: the number of frames of the image output by the camera module between two consecutive times of performing the refresh frequency acquisition operation by the electronic device.

After the operation of acquiring the refresh frequency of the screen is executed, if the frame number of the image output by the camera module reaches the frame number limited by the frame number interval condition, the operation of acquiring the refresh frequency of the screen is executed again.

In step 102, a target image output frame rate used by the camera module is determined according to a currently used refresh frequency of the screen, where the currently used refresh frequency of the screen is an integer multiple of the target image output frame rate.

For example, the refresh frequency currently used by the screen is 60Hz, and the target image output frame rate used by the camera module is determined to be 30fps or 60 fps.

For another example, the current refresh frequency of the screen is 60.6Hz, and the target image output frame rate used by the camera module is determined to be 30.3fps or 60.6 fps.

In step 103, the camera module is controlled to output an image according to the target image output frame rate.

In some embodiments, the current refresh frequency of the screen is an integral multiple of the target image output frame rate used by the camera module, and the camera module is controlled to output images according to the target image output frame rate, so that the display time of each frame of image output by the camera module on the screen is the same, the fluency of image display is improved, and the viewing experience of a user is improved.

For example, fig. 2 is a timing diagram illustrating a screen using a refresh rate of 60.6Hz, a camera module using a target image output frame rate of 30.3fps, and a screen using a refresh rate 2 times the target image output frame rate of the camera module according to an exemplary embodiment, referring to fig. 2. For each frame of image output by the camera module, the time for displaying each frame of image on the screen is all

In some embodiments, the refresh frequency currently used by the screen is not an integer multiple of the image output frame rate used by the camera module, which may cause the screen display time of all images output by the camera module to be not completely the same, resulting in unsmooth image display.

For example, fig. 3 is another timing diagram according to an exemplary embodiment, referring to fig. 3, the refresh frequency used by the screen is 60.6Hz, the image output frame rate used by the camera module is 30fps, and the refresh frequency used by the screen is not an integer multiple of the image output frame rate used by the camera module.

For the first frame image output by the camera module, the time for displaying the first frame image on the screen is

The screen display time of each frame of image output by the camera module is at least ensured

On the premise that each frame of image from the second frame image to the (N-1) th frame image output by the camera module is displayed on the screen for the time of

For the Nth frame image output by the camera module, the time for displaying the Nth frame image on the screen is

According to the method, the image output by the camera module is displayed.

For the Nth frame image and the (N-1) th frame image output by the camera module, the time for displaying the Nth frame image on the screen is longer than the time for displaying the (N-1) th frame image on the screen, so that the image display is not smooth, and the feeling of picture blocking is brought to a user.

Comparing fig. 2 and fig. 3, it can be seen that, when the refresh frequency used by the screen is not an integral multiple of the image output frame rate used by the camera module, the image output frame rate used by the camera module is adjusted by using the method provided by the embodiment of the present disclosure, so that each frame of image output by the camera module has the same screen display time, and the fluency of image display is ensured.

In some embodiments, the electronic device may further detect whether the refresh frequency used by the screen is updated, and if the refresh frequency used by the screen is updated, determine a new image output frame rate used by the camera module according to the updated refresh frequency, and control the camera module to output an image according to the new image output frame rate.

The electronic device can compare the two detected refresh frequencies used by the screen, and if the detected refresh frequency is different from the last detected refresh frequency, the refresh frequency used by the screen is determined to be updated. Or when the screen updates the refresh frequency, sending an update message to enable a processor in the electronic equipment to determine that the refresh frequency used by the screen is updated according to the update message.

There are many occasions when the electronic device detects whether the refresh frequency used by the screen is updated. For example, the electronic device may detect whether the refresh frequency used by the screen is updated at preset time intervals. For another example, the electronic device may detect whether the refresh frequency of the screen usage is updated according to a user instruction.

And the electronic equipment determines a new image output frame rate used by the camera module according to the updated refreshing frequency according to the principle that the refreshing frequency used by the screen is integral multiple of the image output frame rate used by the camera module.

In this embodiment, the electronic device has a function of dynamically detecting whether the refresh frequency used by the screen is updated, and dynamically adjusting the image output frame rate used by the camera module according to the updated refresh frequency, so as to ensure smooth display of multiple frames of images continuously output by the camera module.
