The motor 191 may generate a vibration cue. The motor 191 may be used for incoming call vibration alerting as well as for touch vibration feedback. For example, touch operations acting on different applications (e.g., photographing, audio playing, etc.) may correspond to different vibration feedback effects. The motor 191 may also correspond to different vibration feedback effects by touching different areas of the display screen 194.

The touch vibration feedback effect may also support customization.

The indicator 192 may be an indicator light, may be used to indicate a state of charge, a change in charge, a message indicating a missed call, a notification, etc.

The SIM card interface 195 is used to connect a SIM card. The SIM card may be inserted into the SIM card interface 195, or removed from the SIM card interface 195 to enable contact and separation with the electronic device 100. The electronic device 100 may support 1 or N SIM card interfaces, N being a positive integer greater than 1. The SIM card interface 195 may support Nano SIM cards, micro SIM cards, and the like. The same SIM card interface 195 may be used to insert multiple cards simultaneously. The types of the plurality of cards may be the same or different. The SIM card interface 195 may also be compatible with different types of SIM cards. The SIM card interface 195 may also be compatible with external memory cards. The electronic device 100 interacts with the network through the SIM card to realize functions such as communication and data communication. In some embodiments, the electronic device 100 employs esims, i.e.: an embedded SIM card. The eSIM card can be embedded in the electronic device 100 and cannot be separated from the electronic device 100.

The software system of the electronic device 100 may employ a layered architecture, an event driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. In this embodiment, taking an Android system with a layered architecture as an example, a software structure of the electronic device 100 is illustrated.

Fig. 2 is a schematic diagram of a software system of the electronic device 100 according to an embodiment of the present application. The software system comprises a plurality of layers, each layer has clear roles and division of work, and the layers are communicated through software interfaces. In some embodiments, as shown in fig. 2, the Android system may include five layers, from top to bottom, an application layer 21, an application framework layer 22, a hardware abstraction layer 23, a driver layer 24, and a hardware layer 25, respectively.

The application layer 21 may include camera applications 211, gallery, calendar, talk, map, navigation, WLAN, bluetooth, music, video, short message, etc. applications.

The application framework layer 22 provides an application programming interface (application programming interface, API) and programming framework for application programs of the application layer; the application framework layer may include some predefined functions.

For example, the application framework layer 22 may include a camera access interface; camera management and camera devices may be included in the camera access interface. Wherein camera management may be used to provide an access interface to manage the camera; the camera device may be used to provide an interface to access the camera.

The hardware abstraction layer 23 is used to abstract the hardware. For example, the hardware abstraction layer may include a camera abstraction layer and other hardware device abstraction layers; the camera hardware abstraction layer may call a camera algorithm.

For example, the hardware abstraction layer 23 includes a camera hardware abstraction layer 231 and a camera algorithm 232; various modules of software algorithms for image processing may be included in the camera algorithm module 232, including, for example, an Auto Focus (AF) module 2321.

Illustratively, the algorithms in the camera algorithm 232 may refer to being independent of a particular hardware implementation; such as code that may typically run in a CPU, etc.

The driver layer 24 is used to provide drivers for different hardware devices. For example, the drive layer may include a camera device drive.

The hardware layer 25 may include camera devices as well as other hardware devices.

The embodiment of the application relates to a photographing focusing process, and an AF module is arranged in current electronic equipment and used for realizing photographing automatic focusing. The AF algorithm in the AF module obtains the highest image frequency component by adjusting the position of the focusing lens, thereby obtaining higher contrast. The AF algorithm is a continuously accumulated process of obtaining the best focus point, and the focus distance is obtained by comparing the contrast of each frame image to obtain the maximum contrast point in the lens movement range. Illustratively, the current self-AF module employs a "hill climbing algorithm", which is limited in that it is adapted only to the case where the color difference of the image itself is large.

In order to solve the problem of low user experience caused by slow focusing response speed of electronic equipment in the prior art, the embodiment of the application starts focusing before the electronic equipment detects the end of photographing operation of a user, so that the response speed of the electronic equipment is improved, shutter delay is reduced, and photographing experience of the user is improved.

The embodiment of the application can be applied to various shooting scenes, is particularly suitable for shooting moving targets in moving scenes, for example, shooting faces of people in transverse movement and shooting faces of people in longitudinal movement, can obviously improve the response speed of electronic equipment, and obtains a better shooting effect. Here, the lateral movement means that the object to be photographed moves from one side to the other side of the photographing interface, as in the direction shown in fig. 3, and the longitudinal movement means that the object to be photographed moves from the far side to the near side of the electronic device or moves from the near side to the far side of the electronic device.

Fig. 4 is a schematic flowchart of a photographing method provided in an embodiment of the present application. The method 300 may be performed by an electronic device capable of taking a photograph, or may be performed by a chip in the electronic device, which is not limited in any way. For ease of description, method 300 will be described in detail using an electronic device as an example.

In S310, the electronic apparatus detects a photographing operation of the user.

The photographing operation is an operation in which a user acts on the electronic device in various ways to trigger the electronic device to take a photograph. Illustratively, the photographing operation may be: the operation of pressing the photographing key, or the operation of photographing through a voice instruction, or the operation of photographing through a preset gesture.

In an embodiment in which the photographing operation is an operation of pressing a photographing key, in an example, the photographing key may be an icon key of a touch area of the electronic device.

As shown in fig. 3, after the user turns on the camera, the electronic device displays a photographing interface, where the photographing interface includes a touch area 30, and the touch area includes a photographing key 301, and the user touches the photographing key 301, and the electronic device detects an operation of the user touching the photographing key 301.

Of course, in an embodiment in which the photographing operation is an operation of pressing the photographing key, in other examples, the photographing key may also be a photographing key of a physical entity of the electronic device, which is not limited in this embodiment.

In connection with the software system in the electronic device shown in fig. 2, in S310, the user performs a photographing operation on the camera application 211 of the application layer 21, the camera application 211 detects the photographing operation and the AF module 2321 of the hardware abstraction layer 23 recognizes the photographing operation.

In S320, the electronic device triggers the AF module in response to the photographing operation before detecting that the photographing operation is ended.

The end of the photographing operation means that the user completes the interaction process with the electronic device for triggering the electronic device to photograph.

In the embodiment in which the photographing operation is to press the photographing key, the user presses the photographing key, and after a certain period of time, the user's finger leaves the photographing key, i.e., the user's finger is lifted up relative to the photographing key. Therefore, the operation indicating the end of the photographing operation may be a lifting operation of the finger of the user against the photographing key.

In this step, before detecting that the photographing operation is finished (for example, the lifting operation of the finger of the user against the photographing key), the electronic device triggers the AF module in response to the photographing operation, so that the AF module starts to execute the AF algorithm to perform focusing, so as to perform photographing after focusing is completed.

In conjunction with the software system in the electronic device shown in fig. 2, in S320, before detecting that the photographing operation is finished, the AF module 2321 of the hardware abstraction layer 23 performs an AF algorithm to perform focusing in response to the photographing operation.

In this step, the electronic apparatus may trigger the AF module at any time between the detection of the photographing operation by the user and the detection of the end of the photographing operation, without any limitation, as long as the AF module is triggered before the detection of the end of the photographing operation.

Referring to fig. 5, it is assumed that the user performs a photographing operation at time T1 (e.g., the user presses a photographing button at time T1), ends the photographing operation at time T2 (e.g., the user's finger performs a lifting operation with respect to the photographing button at time T2), ignores a transmission delay between different layers, and may be understood as time T1 when the electronic device detects the photographing operation, may be understood as time T2 when the electronic device detects the photographing operation to end, and may trigger the AF module to perform an AF algorithm at any time between T1 and T2, e.g., the electronic device triggers the AF module at time T3, and a time interval T11 between time T1 and time T3.

In some embodiments, before the photographing operation ends and within a first preset time period after the photographing operation is detected, the AF module is triggered in response to the photographing operation.

The shorter the first preset duration is, the faster the response speed of the electronic equipment to the photographing operation of the user is, and the better the photographing experience of the user is. Conversely, the longer the first preset duration, the slower the response speed of the electronic device to the photographing operation of the user, and the worse the photographing experience of the user.

Illustratively, the first predetermined time period is greater than or equal to 0 milliseconds (ms) and less than or equal to 100ms. For example, the first preset duration is 100ms.

With continued reference to fig. 5, after the electronic device detects the photographing operation at time T1 and the interval duration T11, the AF module is triggered at time T3, where the duration T11 belongs to a duration within a first preset duration.

Ideally, the electronic device triggers the AF module immediately after the time t1 of detecting the photographing operation, where the first preset duration is very short and negligible, and may be considered as 0ms.

In S330, the electronic device focuses through the AF module to take a picture.

In the step, the electronic device executes an AF algorithm through the AF module to focus, and performs real photographing after focusing is completed. Reference is made to related descriptions of the prior art for the AF algorithm, and no further description is given here.

In combination with the software system in the electronic device shown in fig. 2, in implementation, after the AF module 2321 completes the AF algorithm, which means that the focusing process of photographing is completed, the AF module 2321 sends a first instruction to the camera application 211 of the application layer 21 to indicate the focusing state of completing focusing, and after the application layer 21 receives the first instruction, sends a photographing request to the hardware abstraction layer 23, so that the hardware abstraction layer 23 completes photographing in combination with the driving layer 24, the hardware layer 25 and other layers.

With continued reference to fig. 5, the electronic device triggers the AF module at time T3, completes focusing at time T4 after the AF module passes the duration T12, and after T4, the electronic device performs real photographing, and the duration of completing focusing by the AF module is T12.

Note that, in the embodiment of the present application, the time t4 for indicating that the electronic device completes focusing through the AF module may be the time when the AF module sends the first instruction to the camera application 211, or may be the time when the camera application 211 receives the first instruction, which is not limited in any way. If the transmission delay between different layers is ignored, the time when the AF module sends the first instruction is regarded as the same time when the camera application program receives the first instruction.

In some embodiments of the present application, referring to fig. 5, a duration T1 between a time T1 when a photographing operation of a user is detected and a time T4 when focusing is completed by an AF module may be used as a response duration of the electronic device for the photographing operation. That is, the time t1 at which the photographing operation is detected is taken as the start time of the response time period, and the time t4 at which the AF module completes focusing is taken as the end time of the response time period. The shorter the response time length is, the better the response speed of the electronic equipment to photographing operation is.

In other embodiments, referring to fig. 5, a duration T12 between a time T3 when the electronic device triggers the AF module and a time T4 when the AF module completes focusing may be used as a response duration of the electronic device for the photographing operation. That is, the time t3 for triggering the AF module is taken as the start time of the response time, and the time t4 for completing focusing by the AF module is taken as the end time of the response time. The shorter the response time length is, the better the response speed of the electronic equipment to photographing operation is.

For convenience of description, taking a time period T1 between a time T1 when a photographing operation of a user is detected and a time T4 when focusing is completed by the AF module as an example of a response time period of the electronic device for the photographing operation, the response time periods of the present application and the related art are described in comparison with fig. 6.

Fig. 6 is a schematic diagram showing response time durations of an electronic device to a photographing operation in a photographing method of the prior art. For convenience of description in comparison with fig. 5, the time T1, the time T2 and the time T2 in fig. 6 are respectively the same as the time T1, the time T2 and the time T12 shown in fig. 5. In fig. 6, the electronic device detects the photographing operation of the user at time T1, at a first time interval of T0, detects that the photographing operation is finished at time T2, triggers the AF module to perform focusing at time T5, and completes focusing at time T4, wherein the time period for the AF module to perform the AF algorithm to perform focusing is T2, and T2 is the same as the time period T12 for the AF module to perform the AF algorithm to perform focusing in fig. 5, so that the response time period T1 of the electronic device for the photographing operation is longer than the response time period T1 shown in fig. 5 (if the time period T11 between T3 and T1 is the same as the time period between T2 and T5, the response time period T1 of fig. 5 is longer than the response time period T1 of fig. 6 by T0), the response speed is slow, and the photographing experience of the user is bad.

According to the photographing method provided by the embodiment of the application, before the photographing operation of the user is detected, the electronic device triggers the AF module to focus, compared with the method in the prior art that the AF module is triggered to focus after the photographing operation is detected, the photographing method reduces the time from the photographing operation detection to the focusing completion, effectively improves the response speed of the electronic device to the photographing operation, and improves the photographing experience of the user.

When the AF module executes the AF algorithm, in general, when the obtained calculation result is in a convergence state, this means that focusing is successfully completed, and the electronic device performs photographing after focusing is completed. However, in some scenarios, the calculation result obtained when the AF module executes the AF algorithm cannot be converged for a long period of time, so that the electronic device cannot take a picture, which also results in a slower response speed of the electronic device and affects the photographing experience of the user.

Based on this, in the embodiment of the present application, in S330, if the calculation result obtained by the AF module does not converge within the second preset duration, the electronic device forces the calculation result to converge by the AF module so as to take a photograph.

It should be understood that the second preset duration is the longest duration for which the electronic device performs focusing through the AF module to perform the AF algorithm. In addition, the calculation result obtained by the AF module does not converge within the second preset time period, which should be understood that the calculation result obtained by the AF module does not converge at the end time of the second preset time period.

Illustratively, the second predetermined time period is greater than 0ms and less than or equal to 500ms. For example, the second preset duration is 300ms.

And in the second preset time period, if the calculation result of the AF algorithm executed by the AF module is not converged, the electronic equipment forcedly converges the calculation result by the AF module, so that focusing is completed, the AF module sends a first instruction for indicating the focusing state in which focusing is completed to the camera application program of the application layer, and the electronic equipment takes a picture after the camera application program receives the first instruction. Therefore, by setting the second preset time length, the time length of focusing by the AF module can be effectively limited, the problem that the response speed is low due to overlong focusing time length caused by the fact that the calculation result cannot be converged for a long time is avoided, and the photographing experience of a user is further improved.

Referring to fig. 6, in the prior art, after detecting that the photographing operation is finished, the camera application 211 of the application layer 21 sends a trigger event (trigger event) to the AF module 2321 of the hardware abstraction layer 23 at time t5 to trigger the AF module 2321 to perform focusing, and when the response time is counted, the time t5 when the camera application 211 sends the trigger event is taken as a start time, the time when the AF module 2321 finishes focusing is taken as an end time, and the counted time between the two is a response time (or a focusing time called as an AF module).

In implementation, in order to facilitate statistics of the response duration, an existing flow may be reserved, and the time t5 of the trigger event is continued to be used as the starting time of the response duration. That is, in this embodiment of the present application, the electronic device triggers the AF module and performs focusing through the AF module before detecting that the photographing operation of the user is finished, and at the same time, the application layer sends a trigger event to the AF module at time t5 after detecting that the photographing operation is finished, where the trigger event carries a timestamp indicating a time of sending the trigger event, and the time is time t5. Because the AF module has executed the focusing process of the AF algorithm, the AF module cannot be re-triggered according to the triggering event (or the triggering event has no influence on the focusing process of the AF module), and only the timestamp carried by the triggering event is used as the starting time of the statistical response time.

That is, in some embodiments, the method 300 further comprises: and after the electronic equipment detects that the photographing operation is finished, counting the response time of the electronic equipment for the photographing operation based on the time stamp.

The time indicated by the timestamp may be understood as the time of sending the trigger event, i.e. time t5, as described above, and the timestamp is carried in the trigger event.

That is, compared to the above embodiment in which the time at which the photographing operation is detected is taken as the start time of the response time period, this embodiment changes the reference point of the start time of the response time period, taking the time indicated by the above-described timestamp (i.e., the time t5 at which the application layer transmits the trigger event) as the start time of the response time period.

Illustratively, the electronic device may range from 0ms to 70ms in duration between the time that the photographing operation is detected to end and the time that the trigger event is sent by the application layer. For example. The duration may be 50ms.

Here, ignoring the transmission time delay between different layers, the time when the electronic device detects the end of the photographing operation may be understood as the time when the user ends the photographing operation (e.g., the user's finger performs a lifting operation with respect to the photographing key).

Taking fig. 5 and 6 as an example, for example, the electronic device detects that the photographing operation ends at time T2, and sends a trigger event by the application layer at time T5 after time T2, where the response time is T2 with time T5 as the starting time of the response time, and the response time T2 shown in fig. 5 is shorter than the time T2 shown in fig. 6, which indicates that the response speed of the embodiment shown in fig. 5 is fast.
