Detailed Description

The technical solutions of the present application will be specifically described below by way of examples and with reference to the accompanying drawings. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

It should be noted that: in the examples of this application, "first," "second," etc. are used to distinguish similar objects and not necessarily to describe a particular order or precedence.

In addition, the embodiments described in the present application may be arbitrarily combined without any collision. In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

The screen rotation can be to dynamically adjust the content displayed in the screen according to the state of the electronic equipment such as the mobile phone, for example, when the mobile phone is in a vertical state, the content in the mobile phone is also vertically arranged; when the mobile phone is in a horizontal state, the content in the mobile phone is changed into horizontal arrangement.

The screen rotation technology in the related art is to analyze a series of sensor parameters such as a gravity sensor, a gyroscope, a light sensor and the like to judge whether the current state of the mobile phone is changed, and if the state of the mobile phone is changed from a horizontal screen to a vertical screen or from the vertical screen to the horizontal screen, the screen rotation of the mobile phone is controlled.

The screen rotation flow in the related art is as follows: the processing module of the mobile phone continuously receives parameters sent by components such as a light sensor, a gravity sensor, a gyroscope and the like. And the current mobile phone state is judged by calculating the parameters and comparing the parameters with the data obtained by previous experiments under different scenes. And triggering the mobile phone to rotate the screen once the state of the mobile phone is judged to be changed.

In a related technical scheme, a processing module of the mobile phone obtains the current state of the mobile phone by analyzing various sensor parameters on the mobile phone, and once the state of the mobile phone is detected to change (for example, the conversion from a horizontal screen to a vertical screen or vice versa), the screen is triggered to rotate. The scheme of triggering rotation by only analyzing the state of the mobile phone is not combined with the actual user requirement, because in many cases, the state of the mobile phone is changed and does not represent that the user wants to rotate the screen, and the user can only trigger the screen by mistake in the motion state, but the original purpose of the screen rotation technology is to bring convenience in use to the user, the related technology does not consider the requirement of the user, and the scheme of rotating the mobile phone only according to the state of the mobile phone can cause a series of rotations which do not meet the expected requirement of the user, and obviously, the scheme in the related technology cannot meet the requirement of the user.

The embodiment of the application provides a method for intelligent rotation control of a screen based On Always On (AON), which mainly aims at utilizing the AON function to detect and identify the face, and enables the mobile phone screen to intelligently rotate according to the user demand by combining and analyzing the change of the included angle between the face and the screen and the change of the parameters of a mobile phone sensor.

Fig. 1 is a flow chart of a display control method according to an embodiment of the present application, as shown in fig. 1, where the method is applied to a display control device or a processing module of an electronic device, and the method includes:

s101, obtaining first information determined by the camera module and obtaining a rotation angle of the electronic equipment.

The first information may represent whether a target object exists in a shooting range of the camera module.

The camera module in the electronic device may periodically or aperiodically send the first information to the processing module of the electronic device, so that the processing module may periodically or aperiodically acquire each piece of the first information.

At least one of the light sensor, the gravity sensor and the gyroscope in the electronic device can periodically or aperiodically send the detected information to the processing module of the electronic device, so that the processing module can determine the rotation angle of the electronic device based on the information detected by at least one of the light sensor, the gravity sensor and the gyroscope. The light sensor can be used for detecting the brightness of the environment, the gravity sensor can be used for detecting the inclination angle of the electronic equipment relative to the horizontal plane or the vertical direction, and the gyroscope is used for detecting the angle change information of the electronic equipment.

In other embodiments, the processing module may periodically or aperiodically read the detected information from the camera module, and from at least one of the light sensor, the gravity sensor, and the gyroscope.

The rotation angle of the electronic device may be a change angle of the electronic device during or after the rotation process, compared to the electronic device before the rotation. For example, in a case where the length direction (or the width direction) of the electronic device before rotation is parallel to the vertical direction, or an angle with the vertical direction is less than or equal to a target angle, it may be determined that the electronic device is in a portrait screen state. For another example, when the length direction (or width direction) of the electronic device before rotation is perpendicular to the vertical direction, or an angle between the electronic device and the vertical direction is greater than or equal to 90 degrees minus the target angle and less than or equal to 90 degrees plus the target angle, it may be determined that the electronic device is in the landscape screen state. The rotation angle of the electronic device may be determined based on an angle between a length direction (or a width direction) and a vertical direction of the electronic device.

The camera module may obtain a particular image, which may be an image having a pixel size smaller than the target pixel size. The pixel size of the particular image may be smaller than the pixel size of the target image. The camera module can analyze the specific image to determine whether a target object exists in the shooting range of the camera module. Therefore, whether a target object exists in the shooting range of the shooting module or not can be automatically determined through the shooting module according to the shot specific image with the smaller pixel size, and the participation of other processing modules is not needed, so that the power consumption of the electronic equipment can be reduced. In some embodiments, the target object is determined to exist in the shooting range of the shooting module under the condition that the face outline or the face shape can be determined through the pixel information of the pixel points in the specific image. The pixels in the specific image can be very sparse, so that whether a target object exists in the shooting range of the shooting module can be determined through small calculation amount based on the specific image with sparse pixels.

The camera module may send a first value to the processing module if it is determined that the first information characterizes that the target object exists in the shooting range of the camera module, and send a second value to the processing module if it is determined that the first information characterizes that the target object does not exist in the shooting range of the camera module.

The target object may be a person or any other object capable of viewing content displayed by a display module of the electronic device.

In some embodiments, the period of sending the first information configured by the camera module and/or the period of sending the detected information configured by at least one of the light sensor, the gravity sensor and the gyroscope may be preconfigured in the camera module and/or the at least one of the light sensor, the gravity sensor and the gyroscope, so that the camera module and/or the at least one of the light sensor, the gravity sensor and the gyroscope may send the detected information to the processing module based on the preconfigured period.

In other embodiments, the processing device may configure the period of sending the first information to the camera module and/or the processing device may configure the period of sending the detected information to at least one of the light sensor, the gravity sensor, the gyroscope. For example, in a case where the processing device determines that the remaining power of the electronic device is less than the power threshold, or determines that the electronic device turns on the power saving mode, it may be determined that the period of the configuration is large.

In some embodiments, the processing module may obtain the first information determined by the image capturing module and obtain the rotation angle of the electronic device when it is determined that the electronic device is in the open screen state. In other embodiments, the electronic device may obtain the first information determined by the camera module and obtain the rotation angle of the electronic device if it is determined that the electronic device is using the application of the preset type. The preset type of application may be an application that is capable of being displayed across a screen during use. For example, the preset types of applications may include: weChat, video playback class applications, video talk class applications, web browsing class applications, and the like.

In some embodiments, the processing module may send first designation information to the camera module and/or at least one of the light sensor, the gravity sensor, and the gyroscope, where the designation information is used to instruct stopping detection, if it is determined that the electronic device is in the off-screen state, or if a preset type of application is not being used. And the processing device sends second specified information to the camera module and/or at least one of the light sensor, the gravity sensor and the gyroscope when determining that the electronic device is in an open screen state or a preset type of application is being used, wherein the specified information is used for indicating to start detection.

S102, sending second information to a front processing module when the first information characterizes that a target object exists in the shooting range of the shooting module and the rotation angle is larger than a first angle threshold; the second information is used for indicating the preprocessing module to start a normally open AON function, and under the condition that the AON function is started, the preprocessing module determines an included angle between the face of the target object and the display module based on the target image shot by the shooting module.

The first angle threshold may be in the range of 30 degrees to 60 degrees. For example, the first angle threshold may be 30 degrees, 45 degrees, or 60 degrees.

The preprocessing module can respond to the second information, start the normally open AON function, and under the condition that the AON function is started, the preprocessing module can instruct the camera module to shoot the target image once every preset time interval, and the preprocessing module can determine the included angle between the face of the target object and the display module based on the acquired target image.

The pixel size of the target image may be smaller than the specific pixel size. In some embodiments, the preprocessing module may detect a face frame in the target image, and determine an angle between the face of the target object and the display module based on a position of the face frame in the target image. In other embodiments, the preprocessing module may detect the positions of the eyes, hair, nose, mouth, ears, etc. in the target image, and determine the included angle between the face of the target object and the display module.

The preprocessing module can determine an included angle every other preset time length, and then sends the determined included angle to the processing module.

S103, under the condition that the included angle is larger than a second angle threshold or is continuously increased, and the rotation angle is larger than a third angle threshold, converting the display state of the display module from a first display state to a second display state; the third angle threshold is greater than the first angle threshold.

The second angle threshold may be a value greater than or equal to 30 degrees and less than or equal to 90 degrees. For example, the second angle threshold may be 30 degrees, 45 degrees, 60 degrees, 75 degrees, or 90 degrees. In some embodiments, the second angle threshold may be smaller than 90 degrees, so that the display state of the display module is converted from the first display state to the second display state in the rotation process of the electronic device, and switching of the display state of the display module is smoother.

In some embodiments, the first display state may be a portrait display state and the second display state may be a landscape display state. In other embodiments, the first display state may be a landscape display state and the second display state may be a portrait display state.

The processing module may send the content to be displayed to the image conversion module, so that the image conversion module converts the display state from the first display state to the second display state, and outputs the content in the second display state to the display module, so that the display module switches from displaying the content in the first display state to displaying the content in the second display state. The image conversion module may include a graphics processor (Graphics Processing Unit, GPU), among other things.

Fig. 2 is a flow chart of another display control method provided in the embodiment of the present application, as shown in fig. 2, where the method is applied to a display control device or a processing module of an electronic device, and the method includes:

s201, obtaining first information determined by the camera module and obtaining a rotation angle of the electronic device.

S202, sending second information to a front processing module when the first information characterizes that a target object exists in the shooting range of the shooting module and the rotation angle is larger than a first angle threshold; the second information is used for indicating the preprocessing module to start a normally open AON function, and under the condition that the AON function is started, the preprocessing module determines an included angle between the face of the target object and the display module based on the target image shot by the shooting module.

S203, under the condition that the included angle is larger than a second angle threshold or is continuously increased, and the rotation angle is larger than a third angle threshold, converting the display state of the display module from a first display state to a second display state; the third angle threshold is greater than the first angle threshold.

S204, when the included angle is smaller than or equal to the second angle threshold or gradually reduced, and the rotation angle is larger than the third angle threshold, the display state of the display module is kept in the first display state.

Fig. 3 is a flowchart of another display control method according to an embodiment of the present application, as shown in fig. 3, where the method is applied to a display control device or a processing module of an electronic device, and the method includes:

s301, obtaining first information determined by the camera module and obtaining a rotation angle of the electronic device.

S302, sending second information to a front processing module when the first information characterizes that a target object exists in the shooting range of the shooting module and the rotation angle is larger than a first angle threshold; the second information is used for indicating the preprocessing module to start a normally open AON function, and under the condition that the AON function is started, the preprocessing module determines an included angle between the face of the target object and the display module based on the target image shot by the shooting module.

S303, under the condition that the included angle is larger than a second angle threshold or is continuously increased, and the rotation angle is larger than a third angle threshold, converting the display state of the display module from a first display state to a second display state; the third angle threshold is greater than the first angle threshold.

In some embodiments, S305 may be performed after S303.

And S304, when the included angle is smaller than or equal to the second angle threshold or the included angle is gradually reduced and the rotation angle is larger than the third angle threshold, keeping the display state of the display module in the first display state.

In some embodiments, S305 may be performed after S304.

S305, sending third information to the preprocessing module; the third information is used for indicating the preprocessing module to close the AON function; and under the condition that the AON function is closed, the preprocessing module controls the image pickup module to stop shooting the target image.

It can be appreciated that in the event that the AON function is off, the camera module will take a particular image to determine the first information. Under the condition that the AON function is started, the camera module shoots a target image, so that the preprocessing module determines an included angle based on the target image.

In the embodiment of the application, the AON function can be closed under the condition that whether the included angle is larger than the second angle threshold value is determined by opening the normally open AON function, so that the situation that the power consumption of the electronic equipment is increased due to the fact that the AON function is opened for a long time is avoided.

Fig. 4 is a flowchart of another display control method according to an embodiment of the present application, as shown in fig. 4, where the method is applied to a display control device or a processing module of an electronic device, and the method includes:

S401, obtaining first information determined by the camera module and obtaining a rotation angle of the electronic device.

S402, sending second information to a front processing module when the first information characterizes that a target object exists in the shooting range of the shooting module and the rotation angle is larger than a first angle threshold; the second information is used for indicating the preprocessing module to start a normally open AON function, and under the condition that the AON function is started, the preprocessing module determines an included angle between the face of the target object and the display module based on the target image shot by the shooting module.

S403, under the condition that the included angle is larger than a second angle threshold or is continuously increased, and the rotation angle is larger than a third angle threshold, converting the display state of the display module from a first display state to a second display state; the third angle threshold is greater than the first angle threshold.

In some embodiments, S403 may be followed by S404.

S404, starting a timer of the target duration.

The target duration may be a preconfigured duration, or the target duration may be flexibly determined based on a current operating condition of the electronic device. For example, in some embodiments, the processing module may determine the target duration based on whether the current time is evening or morning. In the case where the current time is evening or morning, it is indicated that it is possible for the user to lie in the bed to play the electronic device, and thus the target period that can be configured is long. In other embodiments, the processing module may determine whether the usage scenario of the electronic device is a room or bedroom, where the usage scenario is a room or bedroom, indicating that the user is likely to lie in a bed to play the electronic device, and thus the target time period that may be configured is longer.

S405 and/or S406 may be performed after S404.

And S405, when the included angle is smaller than or equal to the second angle threshold value and the rotation angle is larger than the third angle threshold value in the running period of the timer, switching the display state of the display module from the second display state to the first display state, and sending third information to the preprocessing module.

In some implementation scenarios, the user needs to lie in a bed to use the electronic device, or needs to continue to use the electronic device after getting up, and after the user rotates the electronic device by an angle greater than the third angle threshold, but the face does not follow the rotation of the electronic device, so the electronic device can switch the display state of the display module from the first display state to the second display state, at this time, the electronic device does not immediately turn off the AON function, but predicts that the user will use the electronic device next, so the electronic device can start a timer of a target duration, and in the case that the face rotates to the front of the electronic device during the operation of the timer, the display state of the display module is switched from the second display state to the first display state.

S406, when the included angle is determined to be larger than the second angle threshold value and the rotation angle is determined to be larger than a third angle threshold value during the running of the timer, sending the third information to the preprocessing module.

Wherein the third information is used for indicating the preprocessing module to close the AON function; and under the condition that the AON function is closed, the preprocessing module controls the image pickup module to stop shooting the target image.

Fig. 5 is a flowchart of a display control method according to another embodiment of the present application, as shown in fig. 5, where the method is applied to a display control device or a processing module of an electronic device, and the method includes:

s501, obtaining first information determined by a camera module and obtaining a rotation angle of electronic equipment;

s502, obtaining the ambient light brightness detected by the light sensor under the condition that the first information characterizes that a target object exists in the shooting range of the shooting module and the rotation angle is larger than a first angle threshold.

S503, determining an image enhancement parameter based on the environment light brightness information when the environment light brightness is less than or equal to a light brightness threshold value.

Under the condition that the ambient light brightness is larger than the brightness threshold, the definition of the target image meets the requirement, and the shot target image does not need to be subjected to image enhancement. In the case where the ambient light level is less than or equal to the light level threshold, the face portion is not easily recognized, and therefore, the image enhancement processing can be performed on the target image using the image enhancement parameters.

And under the condition that the ambient light brightness is less than or equal to the brightness threshold value, different ambient light brightness has different image enhancement parameters. For example, one ambient light level is within a first light level range, the determined image enhancement parameter is a first image enhancement parameter, the other ambient light level is within a second light level range, the determined image enhancement parameter is a second image enhancement parameter, and the first image enhancement parameter and the second image enhancement parameter may be different. In some embodiments, the processing module may obtain a mapping relationship between the plurality of luminance ranges and the plurality of image enhancement parameters, thereby determining, based on the mapping relationship, an image enhancement parameter corresponding to the obtained ambient light luminance. The plurality of luminance ranges may be in one-to-one correspondence with the plurality of image enhancement parameters.

The image enhancement parameters may include at least one of: image signal processing (Image Signal Process, ISP) lightening parameters, night scene lightening parameters.

S504, sending second information and fourth information to the preprocessing module; and the fourth information indicates the preprocessing module to process the target image shot by the shooting module by adopting the image enhancement parameters, and the included angle is determined based on the processed image.

In this way, the image enhancement parameters are adopted to process the target image shot by the shooting module, so that a clearer facial image can be obtained, and the accuracy of the determined included angle is improved.

S505, under the condition that the included angle is determined to be larger than a second angle threshold or is continuously increased, and the rotation angle is determined to be larger than a third angle threshold, converting the display state of the display module from a first display state to a second display state; the third angle threshold is greater than the first angle threshold.

Fig. 6 is a flowchart of a display control method according to another embodiment of the present application, as shown in fig. 6, where the method is applied to a display control device or a processing module of an electronic device, and the method includes:

s601, when the first information determined based on the first configuration information characterizes that a target object exists in a shooting range of the shooting module and fifth information sent by the preprocessing module is received, second configuration information for identifying the target object is sent to the shooting module; the fifth information indicates that the target object is not present in the image capturing module.

S602, obtaining the first information determined by the camera module based on the second configuration information, and obtaining the rotation angle of the electronic equipment.

The first configuration information and the second configuration information may include a target object recognition model, and in the case where the image capturing module obtains the specific image, the specific image may be input to the target object recognition model, thereby determining whether the target object exists in the specific image based on the target object recognition model.

In this way, in the case where it is determined by the first configuration information that the recognition result of the target object is inaccurate, it is possible to determine whether the recognition result of the target object is present by the second configuration information.

The second configuration information may be obtained by modifying the first configuration information. The second configuration information may be obtained through user input.

In some embodiments, the first configuration information may indicate that the resolution of the particular image is a first resolution and the second configuration information may indicate that the resolution of the particular image is a second resolution, the second resolution being greater than the first resolution. In this way, since the second resolution is larger than the first resolution, the conclusion as to whether or not the target object exists within the photographing range of the photographing module, which can be determined by the second resolution, is more accurate.

In some possible embodiments, the processing module may configure the second configuration information to the image capturing module when the ambient light level is less than or equal to a certain threshold value, and configure the first configuration information to the image capturing module when the ambient light level is greater than a certain threshold value. In other possible embodiments, the processing module may configure the second configuration information to the camera module when the current time belongs to the night time period, and configure the first configuration information to the camera module when the current time belongs to the day time period.

S603, sending second information to a front processing module when the first information characterizes that a target object exists in the shooting range of the shooting module and the rotation angle is larger than a first angle threshold; the second information is used for indicating the preprocessing module to start a normally open AON function, and under the condition that the AON function is started, the preprocessing module determines an included angle between the face of the target object and the display module based on the target image shot by the shooting module.

S604, under the condition that the included angle is determined to be larger than a second angle threshold or is continuously increased, and the rotation angle is determined to be larger than a third angle threshold, converting the display state of the display module from a first display state to a second display state; the third angle threshold is greater than the first angle threshold.

s701, obtaining facial feature information of a user using the electronic device.

In some embodiments, facial feature information of the user may be determined based on the obtained historical target images. In other embodiments, facial feature information of the user may be determined based on an album in the electronic device. In still other embodiments, facial feature information of the user may be determined based on facial information uploaded by the user.

S702, determining third configuration information which is sent to the image pickup module and used for identifying the face of the target object based on the facial feature information.

The facial feature information may be facial feature information of one image or facial feature information of at least two images. In some embodiments, the location of the face of the target object in the target image may be determined by a convolutional neural network. For example, the position of the two eyes of the target object in the target image, the position of the mouth of the target object in the target image, and so on. The third configuration information may be parameter information of the convolutional neural network. The third configuration information may be trained based on facial feature information.

S703, sending the third configuration information to the preprocessing module; the third configuration information is used for indicating the preprocessing module to identify the face of the target object based on the third configuration information.

S704, obtaining first information determined by the camera module and obtaining a rotation angle of the electronic device.

S705, sending second information to a front processing module when the first information represents that a target object exists in the shooting range of the shooting module and the rotation angle is larger than a first angle threshold; the second information is used for indicating the preprocessing module to start a normally open AON function, and under the condition that the AON function is started, the preprocessing module determines an included angle between the face of the target object and the display module based on the target image shot by the shooting module.

In S705, the preprocessing module may determine an angle between the face of the target object and the display module based on the third configuration information.

S706, switching the display state of the display module from a first display state to a second display state under the condition that the included angle is determined to be larger than a second angle threshold or is continuously increased and the rotation angle is determined to be larger than a third angle threshold; the third angle threshold is greater than the first angle threshold.

In this application implementation, first, a primary control may be performed, where in the primary control, an AON sensor (corresponding to the above-mentioned camera module) may be combined with a Human Existence (HE) function, and if no Human body is detected currently or parameters of the sensor indicate that no change has occurred in the state of the mobile phone (for example, no switching between landscape and portrait screen states is generated), the AON function is not turned on to perform face detection and recognition, and at this time, intelligent rotation is not enabled. The intelligent rotation is based on the user, and if the user is not found, the screen rotation is meaningless, so that most invalid identification can be effectively reduced, and the power consumption is reduced.

If the primary control is passed, the secondary control is entered, in the secondary control, if the human body is detected and the parameters of the sensor display the state of the mobile phone and change, the pre-configuration processing chip is started to start the AON function so as to perform face detection and identification. The face detection recognition may be performed by an embedded neural Network Processor (NPU) in the preprocessing module described above.

When face detection and recognition are carried out, the current light condition can be judged according to the parameters of the light sensor, and when the light state is poor, the night scene algorithm of ISP (Internet service provider) brightening and/or NPU (non point-of-view) is started to improve the recognition precision. ISP brightening may be performed by a preprocessing module prior to inputting the image to the NPU. The night vision algorithm of the NPU may be performed by the NPU.

In this way, the processing module continuously receives the included angle between the face and the screen transmitted by the NPU, and then judges the motion state of the mobile phone by combining the parameters of each sensor of the mobile phone. If the included angle between the face and the screen is continuously increased, the mobile phone sensor parameters indicate that the state of the mobile phone is changing, and the mobile phone is triggered to rotate the screen. If it is detected that the state of the mobile phone is changing, and the angle between the face of the user and the screen is not significantly changed or is continuously decreasing, it indicates that the user does not want to rotate the screen at this time (for example, when the mobile phone is used by lying on his side, the state of the mobile phone is changed at this time, the conventional screen rotation control strategy triggers the screen rotation, and in fact, the user does not want the screen rotation at this time), and the control of the screen rotation is prevented.

The processing module can also analyze the change rule of the face angle, so that the system can be informed to conduct intelligent rotation in advance. In the process of changing the angle between the face and the screen, the state of the mobile phone may not be changed (for example, the mobile phone is in the 45-degree state in fig. 1), at this time, according to the rule of analyzing the angle change, the operation of rotating the screen can be triggered in advance.

After the control is completed, the AON function is closed, the control of the screen rotation is ended, and the next wake-up trigger is waited.

The use of AON functionality in the embodiments of the application brings the following advantages to screen rotation:

1. screen rotation is more intelligent: the screen is not rotated fixedly according to the state of the mobile phone, and the use state of the user is combined, so that the mobile phone is more friendly to the user.

2. The screen rotation speed is faster: through the contained angle trend of analysis face and screen, can trigger screen rotation control in advance, compare traditional scheme that can only wait for the cell-phone state to change the back and trigger rotatory, the speed is faster, user experience is better.

3. More power consumption is saved: by the two-level control scheme, a large portion of the ineffective screen rotation control can be filtered out compared to conventional rotation schemes. Because the animation of the screen rotation is realized by the GPU, the power consumption is relatively high, and the power consumption of the electronic equipment can be saved by filtering out a large amount of invalid control.

According to the embodiment of the application, the intelligent rotation secondary control is realized by utilizing the characteristic that the AON sensor can detect the human body under the condition that a shot target image is not transmitted, and the intelligent rotation of the screen according to the user requirement is realized by utilizing the face detection and identification capability in the AON function and the traditional method for reading and analyzing the mobile phone sensor parameters.

In the embodiments of the present application: 1. the AON function is utilized to detect and identify the face information (whether the human body exists, the included angle between the face and the screen, the change trend of the included angle and the like) as the basis for controlling the intelligent rotation of the screen. 2. The whole intelligent rotation control process is divided into two stages, and whether the two stages of recognition is carried out or not is judged through the HE function of the AON sensor, so that a part of invalid rotation can be filtered, the frequency of AON starting is reduced, and the power consumption is reduced.

In the embodiment of the application, 1, in a strategy of screen rotation, a face detection scheme based on an AON function is added, and whether screen rotation is performed or not is determined by continuously analyzing the change of the face angle and judging the current state of a mobile phone by combining a mobile phone sensor when the change of the face angle meets a certain rule. Meanwhile, the screen rotation can be triggered in advance according to the rule of analyzing the angle change, and the response speed is improved. 2. The control is divided into two stages, the first stage, the AON function is started to perform intelligent rotation by utilizing the HE function (not transmitting a shot target image and having low power consumption) of the AON sensor, and under the condition that a person is identified, the sensor parameters display that the state of the mobile phone is changed; and secondly, on the basis of detecting a person, starting an AON function to perform face recognition detection, and continuously analyzing face angle change to synthesize mobile phone sensor data so as to achieve the effect of intelligent rotation.

The intelligent rotation scheme of the screen in the embodiment of the application can be based on a system, or the application program can also adopt the change of the angle between the analysis face and the screen to adjust and change the application program, so that better user experience is brought.

Fig. 8 is a schematic diagram of a display control flow provided in the embodiment of the present application, as shown in fig. 8, when the rotation angle of the electronic device is 90 degrees, but the included angle between the face of the target object and the display module is gradually increased, for example, the included angle is gradually changed from 0 degrees to 45 degrees and then to 90 degrees, the display state of the display module is changed from the first display state to the second display state, that is, the electronic device is changed from the vertical display to the horizontal display, and the horizontal display is switched before the included angle is changed to 90 degrees. For example, in the case of an included angle of 45, the display will be changed from a portrait display to a landscape display.

Fig. 9 is a schematic diagram of another display control flow provided in this embodiment of the present application, as shown in fig. 9, when the rotation angle of the electronic device is 90 degrees, but the included angle between the face of the target object and the display module is sequentially reduced, for example, the included angle is gradually changed from 90 degrees to 45 degrees and then to 0 degrees, in this case, the electronic device will maintain the first display state, that is, after the electronic device rotates 90 degrees, since the included angle between the face of the target object and the display module is always reduced, the electronic device will maintain the display of the first state.
