Description

Technical Field

[0001] This application relates to the field of electronic technology, and includes, but is not limited to, a screen control method, apparatus, device, and computer program product. Background Technology

[0002] In shooting scenarios, users often want to view the composition of the scene in real time on the display screen to optimize the shooting effect. To this end, related technologies typically employ a method where the display screen remains on after the camera is activated, allowing the subject to observe the content of the scene and make adjustments. This solution acquires images through the camera and displays them on the screen in real time, facilitating user adjustments to posture or position. However, because the display screen continues to operate even when not needed, prolonged illumination consumes a significant amount of power, easily leading to severe overheating of the device and a substantial increase in overall power consumption, thereby impacting system performance and user experience. Summary of the Invention

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of the embodiments will be further described in detail below with reference to the accompanying drawings. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0034] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0035] In the following description, the terms "first, second, third" are used merely to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first, second, third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0037] This application provides a screen control method, such as... Figure 1 As shown, the method includes:

[0038] Step S110: In response to the trigger command, a captured image of the acquisition area is obtained through the camera, wherein the acquisition area includes the target object;

[0039] Here, the trigger command can be a signal issued by the user through a specific operation, such as pressing the camera button, unfolding the device, or waking up with voice, to start the camera. This command can take various forms, including hardware button input, software interface clicks, and gesture recognition. For example, when the user clicks the camera button or speaks a command to take a picture, the system can recognize this as a trigger command and activate the camera.

[0040] The capture area refers to the spatial region within the camera's field of view, typically presented as an image. The system defines the target object as an individual within this area that needs to be captured or monitored, such as a person or an object. The captured image is the image data obtained by the camera, which may contain multiple target objects and their behavioral information.

[0041] During implementation, when the user presses the camera button or unfolds the device, the system immediately activates the camera and begins capturing images, ensuring that the desired scene is captured. This process improves operational efficiency and provides a data foundation for subsequent intelligent judgment.

[0042] In some embodiments, when the first display screen is in a screen-off state, the system can respond to a trigger command and acquire an image of the acquisition area via the camera. Here, "screen-off state" refers to a state where the electronic device screen is off, but the system continues to operate in the background with low power consumption, and some functions (such as notifications and music playback) can continue to work; that is, the screen is completely off and not displaying anything.

[0043] Step S120: Obtain the status information of the first display screen;

[0044] Here, the display output area of ​​the first display screen is located on the first surface of the electronic device, and the lens of the first camera is also located on the first surface of the electronic device. For example, the camera could be the front-facing camera of a laptop; in a foldable device, the first surface of the electronic device typically serves as the mounting surface of the first display screen, allowing the user to view the content through the first display screen without unfolding the device, and the camera is the rear-facing camera of the foldable device.

[0045] The first display screen status information refers to whether the first display screen is currently on or off. The system can obtain the first display screen status information by reading the registers of the first display screen controller or by calling the operating system interface. For example, if the user does not actively turn on the first display screen or the system determines that the conditions for turning on the first display screen are not met, the system can control the first display screen to remain off to achieve energy saving; while during user use, if the system determines that the conditions for turning on the screen are met, it can control the first display screen to turn on.

[0046] During implementation, the system can simultaneously detect the working status of the first display screen after the camera is activated to determine whether to proceed to the next monitoring step. This mechanism of simultaneously detecting the working status of the first display screen after camera activation helps reduce unnecessary resource consumption and improve system operating efficiency.

[0047] Step S130: If the status information indicates that the first display screen is in a screen-off state, monitor the target object;

[0048] Here, "screen-off state" refers to a state where the electronic device's screen is off, but the system continues to run in the background with low power consumption. Some functions (such as notifications and music playback) can continue to work; that is, the screen is completely off and not displaying anything. Sensors on the screen, such as the camera, are turned off, and the processor only stores information related to the screen display. Screen-off state is completely different from screen-lock state. In screen-lock state, the device screen is on, and it can display a pure black page as a background or a user-preset image. The power consumption of the electronic device in screen-lock state is higher than that in screen-off state.

[0049] When the system determines that the primary display screen is in a screen-off state (i.e., without needing to first start or turn on the screen), the system can initiate the target object monitoring function. Target object monitoring includes, but is not limited to, facial recognition, gaze direction analysis, and gesture detection. Operations such as facial recognition, gaze direction analysis, and gesture detection rely on image processing algorithms and artificial intelligence models. For example, gaze recognition can be achieved based on facial landmark detection algorithms, or gesture recognition algorithms can be used to determine whether the user has preset gestures.

[0050] During implementation, the system can continuously analyze the behavior of target objects in the captured images without turning on the first display screen (in a screen-off state), thus avoiding unnecessary power consumption (when the screen is on). For example, when the system detects that the target object is looking directly at the camera and maintains that gaze for a certain period of time, the system considers the screen-on condition met and triggers the first display screen to light up.

[0051] Step S140: If the first parameter of the target object meets the screen-on condition, control the first display screen to be in the screen-on state and display the acquired image through the first display screen;

[0052] The display output area of ​​the first display screen is located on the first surface of the electronic device, and the lens of the camera is located on the first surface of the electronic device.

[0053] Here, the screen-on condition refers to a set of judgment criteria set based on the behavioral characteristics of the target object. For example, the target object's posture meets a specific angle, the time spent looking at the camera or the first display screen exceeds a threshold, or a preset gesture is detected. When the system determines that the target object meets the screen-on condition, the system will control the first display screen to switch from a screen-off state to a screen-on state and display the captured image on the first display screen.

[0054] During implementation, when the system detects that the target object meets the screen-lighting conditions, it will illuminate the first display screen and display the captured image in real time. This allows the subject to view the current composition and adjust their posture or position to achieve a more ideal shooting effect. By illuminating the first display screen and displaying the captured image in real time only when the target object meets the screen-lighting conditions, the system significantly reduces power consumption, making it particularly suitable for foldable devices with limited heat dissipation capabilities.

[0055] In this embodiment, the camera is activated to capture images in response to a trigger command while the first screen is off. The screen's on / off state is dynamically controlled based on the first display screen's status information, thereby effectively reducing power consumption while ensuring a good user experience (the screen lights up while the user is focused on the image being captured). This ensures the first display screen only lights up when the target object meets the screen-on conditions; otherwise, it remains off, avoiding the high power consumption problem caused by a constantly lit first display screen in traditional solutions. Furthermore, various intelligent recognition technologies, such as face recognition, gaze recognition, and gesture unlocking, further enhance the system's intelligence and interaction efficiency.

[0056] In some embodiments, such as Figure 2A As shown, the above screen control method can also be implemented through the following steps:

[0057] Step S210: If the status information indicates that the first display screen is in the on state, the captured image is displayed on the first display screen;

[0058] Here, "screen on" refers to the state where the display screen is turned on and displaying images normally. The system's power management module determines whether to enter screen on state based on the target object's operation, sensor data, or application instructions. Using screen on state as one of the prerequisites for determining whether to activate the primary display screen's display function ensures that the display is only activated when needed, thereby achieving energy-saving goals.

[0059] In practical applications, the screen-on state of a device may be triggered by various factors, such as user touch screen, issuing voice commands, performing facial recognition, recognizing eye gaze points, and executing gesture recognition. The system can determine whether to enter the screen-on state based on input signals such as user touch screen, voice commands, facial recognition results, eye gaze point recognition results, and gesture recognition information, and display the corresponding captured image when the conditions are met.

[0060] When the device detects that the current status information indicates the first display screen is lit, it means the system has activated the first display screen by detecting the target object. At this time, the system can display the captured image on the first display screen in real time, allowing the subject to view the composition and make adjustments. For example, in a selfie scenario, the subject can preview the image content on the first display screen, thus better posing or adjusting the angle. When using the external screen of a foldable phone to shoot the subject, the subject can preview the image content on the first display screen, thus better posing or adjusting the angle.

[0061] Step S220: If the second parameter of the target object satisfies the screen-off condition, control the first display screen to be in the screen-off state.

[0062] When the system detects that the second parameter of the target object meets the set screen-off conditions, the system will automatically control the first display screen to enter a screen-off state. The second parameter of the target object may include behavioral characteristics such as the target object's gaze direction, head posture, and hand movements. For example, if the target object does not look at the image acquisition device for a long time, or if the target object moves away from the image acquisition device to a certain distance, the system can determine that it is not necessary to continue displaying, and thus the system will turn off the first display screen to save power.

[0063] In some embodiments, the second parameter and the first parameter may correspond to the same index parameter. For example, the gaze direction of the target object (the point of human eye fixation) may be considered. If the point of human eye fixation is located on the camera or the first screen, the screen-on condition is determined to be met. If the point of human eye fixation is not located on the camera or the first screen, the screen-off condition is determined to be met.

[0064] In some embodiments, the second parameter may be a parameter completely different from the first parameter. For example, the second parameter may be an indicator parameter such as head pose, the distance between the target object and the electronic device, or whether the target object is located in the area that the camera can capture.

[0065] Screen-off conditions are a set of logical rules used to determine whether the display needs to be turned off. Screen-off conditions can be set according to specific application scenarios, such as setting a time threshold (e.g., no eye contact within 3 seconds) or a spatial distance threshold (e.g., more than 5 meters). The design of screen-off conditions aims to reduce the time the screen is on as much as possible without affecting the user experience, thereby reducing power consumption.

[0066] During implementation, the screen-off condition can be determined through various methods such as face detection algorithms, eye-tracking algorithms, and gesture recognition algorithms. For example, the FaceLandmark algorithm can be used to detect the eye position of the target object. If the system determines that the target object's gaze is no longer looking at the image acquisition device, the screen-off logic is triggered. Alternatively, an infrared sensor can be used to detect changes in the distance between the target object and the image acquisition device, and the system can then determine whether the primary display screen needs to be turned off.

[0067] Step S210 initiates the image display process after detecting a screen-on state; while step S220 terminates the image display process after detecting that the screen-off condition is met. Together, they constitute a complete dynamic display control mechanism, ensuring that the first display screen is only turned on when the subject actually needs to view the screen content, thereby achieving energy-saving effects.

[0068] In this embodiment, the function of displaying or turning off the first display screen at appropriate times is achieved through intelligent judgment of the external screen's on / off state and dynamic detection of screen-off conditions. By introducing a screen-off condition judgment mechanism into the system, this mechanism can ensure that the subject can view the captured image on the first display screen while automatically turning off the first display screen when the subject does not need to view the preview screen. This can effectively reduce device power consumption, extend battery life, improve device battery endurance, and maintain a good photography interaction experience.

[0069] In some embodiments, the above step S120 "obtaining the status information of the first display screen" can be achieved through the following process:

[0070] Obtain the first state information of the first display screen and the second state information of the second display screen;

[0071] Here, the second display screen refers to the main display area of ​​an electronic device, which is usually located on the front of the device and is used to display the user interface and application content.

[0072] The first display screen refers to the secondary display area of ​​an electronic device, located on the first surface of the device. This first surface is not adjacent to the second surface and is typically located on the back or other non-front position of the electronic device. It serves to assist in display or for interaction in energy-saving modes. For example, in a foldable phone, the first display screen may be located on the back of the foldable phone.

[0073] Screen on: This indicates that the display is active and can display images or text, rather than being off or in sleep mode.

[0074] The difference between the first and second displays lies in their physical location and usage scenarios. The second display is suitable for regular operation and prolonged interaction, while the first display is more often used for energy-saving displays or auxiliary displays.

[0075] In foldable devices, the first display screen is often used for quick access or photo previews when the device is folded outwards, which is especially useful in scenarios involving multiple people taking selfies or group photos.

[0076] During implementation, the system can determine whether it is appropriate to enable a specific display logic by obtaining the status information of the two displays. For example, in a shooting scenario, the first display may be off to save power, while the second display can serve as a preview window for the photographer. If the subject is looking at the first display, it may be on as a preview window for the subject.

[0077] If the second state information of the second display screen indicates that the second display screen is in a bright state, the captured image is displayed on the second display screen.

[0078] When the system detects that the second display screen is on, it will output the captured image (such as the camera preview) to the second display screen so that the photographer can observe the shooting effect of the camera preview in real time.

[0079] The display output area of ​​the second display screen is located on the second surface of the electronic device, and the first surface and the second surface are not adjacent.

[0080] During implementation, the second display screen can be turned on simultaneously with the first state information of the first display screen and the second state information of the second display screen, and the captured image can be displayed on the second display screen. For example, when a user is taking a picture using the rear camera of a foldable phone, the outer screen of the phone (the first display screen) that houses the rear camera can be in a blackout state, while the inner screen of the phone (the second display screen) can display the captured image, allowing the photographer to observe the shooting effect of the camera preview in real time.

[0081] In this embodiment, the second display screen is dynamically controlled based on the acquired display screen status information. This significantly reduces power consumption, improves device operating efficiency, and effectively reduces heat generation while ensuring a good photography experience. Intelligent display management is achieved. This intelligent display management can save power resources and improve overall user satisfaction.

[0082] In some embodiments, the "responding to the trigger command" in step S110 above can be achieved through the following steps:

[0083] If the detection parameters indicate that the first body and the second body satisfy the bending angle and the camera is in the acquisition state, the acquired images are continuously stored as multiple frames in the video file.

[0084] The first display screen and the camera are fixed to the first body, the second display screen is fixed to the first body and the second body, the display output area of ​​the first display screen and the lens of the camera are located on the first surface of the first body, and the second display screen is located on the second surface formed by the first body and the second body.

[0085] Here, the first body and the second body together constitute the main structure of the device, with the first body housing the first display screen and camera of the electronic device. Figure 2B This is a schematic diagram of the structure of a foldable phone provided in an embodiment of this application, such as... Figure 2B As shown, the foldable phone includes a first body 21 and a second body 22. The first body 21 and the second body 22 together constitute the main structure of the foldable phone. The first body 21 houses the first display screen (outer screen) and the (rear) camera, located on the first surface, i.e., on the back of the first body 21. The second body 22 can be a flip-out or sliding part. The second body 22 and the first body 22 can jointly house the second display screen (main screen), such as the main screen in the unfolded state of the foldable phone, providing a larger viewing area when the phone is unfolded. It is located on the second surface, i.e., on the front of the foldable phone. The combination of the first body 21 and the second body 22 enables the device to achieve diverse usage scenarios in different forms.

[0086] Detection parameters refer to a set of sensor data used to determine whether an electronic device has entered smart display mode, such as angular displacement, pressure sensing, and gyroscope signals. These detection parameters collectively reflect the current physical state and intended use of the electronic device. For example, in a foldable phone, when the screen is opened to a specific angle, the system can infer that the user has activated the recording function.

[0087] When the bending angle between the first and second bodies of the foldable device reaches a preset threshold, it indicates that the user is recording video. At this time, the system determines that the camera is in capture mode and starts the continuous capture function, storing each captured image frame sequentially as multiple frames in a video file. For example, the recording function can be started when the bending angle between the first and second bodies of the foldable phone is approximately 90 degrees. Figure 2C This application provides a scenario for recording video using the outer screen of a foldable phone, such as... Figure 2C As shown, the video recording function can be activated when the folding angle of the phone is approximately 90 degrees.

[0088] During implementation, by combining bending angle detection with camera status assessment, the system can automatically activate the intelligent display logic without requiring the user to manually turn on the external screen. This approach, combining bending angle detection with camera status assessment and automatic activation of the intelligent display logic, improves the user experience and effectively reduces device power consumption.

[0089] In this embodiment, the system determines to activate the recording function by detecting the bending angle of the device and the camera's acquisition status. This control method enables the system to intelligently identify the user's recording needs, effectively improving the user's shooting experience and extending the device's battery life.

[0090] In some embodiments, such as Figure 3A As shown in the figure, this application provides a method for determining a target object, which can be implemented through the following steps:

[0091] Step S310: Identify the acquired image and determine at least one subject being photographed;

[0092] Here, "image acquisition" refers to real-time footage or still images captured by a camera for subsequent processing and analysis. In this application, the system uses the acquired images as the basic data source for intelligently determining whether to enable the external screen display function.

[0093] The recognition process can use face detection algorithms (such as Haar cascade, MTCNN, YOLO, etc.) to process the acquired images in order to extract the contours and facial information of the people in the acquired images.

[0094] By recognizing the acquired images, the system can determine that there is at least one subject in the acquired images, and then automatically determine whether there is a subject in the camera's field of view, and further identify the specific target object, thereby realizing the intelligent control logic of the external screen display function, so as to reduce unnecessary power consumption.

[0095] Step S320: Determine the target object based on the facial pose of the at least one photographed object.

[0096] Here, facial pose refers to parameters such as head angle and gaze direction calculated using facial landmark detection algorithms. These parameters are used to determine whether the subject is facing the camera directly or looking at the camera.

[0097] During implementation, the system can analyze the head orientation and eye gaze direction of each subject being photographed. If a target's gaze is directed at the camera for an extended period, the target can be identified as the primary subject for photographing.

[0098] For example, when taking a group photo, the system can identify the direction of each person's gaze, prioritize those who are looking directly at the camera as the target, and then decide whether to enable the external screen display function based on the identified target.

[0099] In this embodiment, at least one subject is identified by recognizing the captured image, and the target object is determined based on facial pose. By employing deep learning-based object detection and facial pose detection, the target object can be accurately identified among multiple subjects, enabling the system to intelligently determine whether to enable the external screen display function, thereby saving power consumption and improving the user experience.

[0100] In some embodiments, step S320 above, "determining the target object based on the facial pose of the at least one photographed object," can be achieved through the following steps:

[0101] Step 321: Obtain the face bounding box of each subject in the captured image;

[0102] Here, a face bounding box refers to a rectangular frame used by a face recognition algorithm to locate and mark each possible face region in the captured image. This rectangular frame defines the positional range of the face within the image and serves as the basis for subsequent determination of whether it is a target object.

[0103] Face recognition algorithms are typically based on deep learning models, such as YOLO and MTCNN, which can quickly and accurately identify face regions in images and output the corresponding coordinate information.

[0104] In practical applications, when a user activates the camera, the system analyzes the image stream in real time and extracts all face frames, providing a data foundation for subsequent filtering.

[0105] By quickly identifying whether a face exists in an image, efficient image processing can be achieved, thereby avoiding unnecessary waste of computing resources and improving overall recognition efficiency.

[0106] Step 322: If the target face frame is larger than the preset size, the subject being photographed corresponding to the target face frame is determined as a candidate subject;

[0107] Here, the preset size refers to a minimum face frame size threshold set based on the device screen size and application scenario. Only faces exceeding the preset size are considered valid subjects. For example, in a foldable device, if the face frame area is less than 40 pixels × 40 pixels, the system considers the face too small to meet the composition requirements. Therefore, it filters out subjects with excessively small faces, avoiding recognition errors or misjudgments due to small faces, while also saving computing resources.

[0108] During implementation, the system can compare the size of each face frame with the preset size, and retain only the subjects corresponding to faces that meet the standard as candidate subjects for further processing.

[0109] Step 323: Identify the facial pose of the candidate object;

[0110] Here, facial pose refers to the angle of a person's face relative to the camera, typically including pitch, yaw, and roll. These parameters are used to determine whether the face is facing the camera directly, thus deciding whether the face is suitable as a target.

[0111] During implementation, the system can obtain facial feature points by using facial key point detection algorithms (such as Dlib, OpenCV, etc.), and then use these facial feature points to calculate the pose angle of the face.

[0112] For example, if a person's face is turned too far to the side, this may result in poor image composition and affect the shooting effect. Therefore, the system needs to exclude situations where the face is turned too far to the side.

[0113] By using the pose recognition function, the system can further filter out suitable target objects, thereby improving the user's photography experience.

[0114] Step 324: If the face pose of the candidate object meets the preset pose, the candidate object is determined as the target object.

[0115] Here, preset posture refers to a set of posture angles set by the system, such as a pitch angle between -15° and 15°, and a yaw angle between -20° and 20°. This angle range indicates that the face is basically facing the camera, which is suitable for shooting.

[0116] When the posture of the candidate object meets the conditions, the system confirms the candidate object as the target object, that is, the final subject of the shot.

[0117] Figure 3B This is a schematic diagram of a method for determining facial pose, provided as an embodiment of this application. Figure 3B As shown in the diagram, the schematic includes a three-dimensional coordinate system based on the human face, comprising an x-axis, a y-axis, and a z-axis, wherein...

[0118] The angle by which a face rotates around the x-axis of the coordinate system can be defined as the yaw angle; the angle by which a face rotates around the y-axis of the coordinate system can be defined as the pitch angle; and the angle by which a face rotates around the z-axis of the coordinate system can be defined as the roll angle.

[0119] In some embodiments, if the yaw angle of a face is too large, that is, the closer the captured face is to the side profile, the probability of the face being a passerby is high, and it can be filtered out, that is, not monitored as a target object.

[0120] Here, the priority for determining face pose using the three rotation angles mentioned above is as follows: yaw angle > pitch angle > roll angle. That is, the yaw angle is used first for judgment; if the presence of a target object cannot be determined, the pitch angle is used for judgment; if the presence of a target object cannot be determined using the pitch angle, the roll angle is used last.

[0121] The above steps combine information from two dimensions: face frame size and pose, to ensure that the selected object not only meets the composition requirements but also has good recognition stability.

[0122] In this embodiment, the target object is determined by acquiring a face bounding box, filtering candidate objects that meet the specified size, recognizing the pose, and verifying whether preset conditions are met. This method can reduce invalid recognition, improve recognition efficiency, thereby reducing power consumption and ultimately enhancing user experience and system performance.

[0123] In some embodiments, the above screen control method can also be implemented through the following steps:

[0124] Step S150: When acquiring multiple frames of the acquired images, determine that the gaze focus of the target object in the target acquired image is located on the first display screen;

[0125] During the acquisition of multiple frames of images, the system analyzes each frame using an image recognition algorithm to determine whether the target object (such as the subject being photographed) in the target image is looking at the first display screen. This determination of whether the target object is looking at the first display screen can be based on face detection and eye orientation estimation techniques, such as extracting facial key points and calculating pupil orientation to determine the focal point of the gaze.

[0126] When the focus of the target object's gaze falls on the first display screen in the captured image, it indicates that the target object is paying attention to the content displayed on the first display screen. This usually means that the target object wants to view the current scene, participate in composition adjustments, or has a need to capture the currently displayed image. For example, when a user is using the video recording function, it can be determined that the subject is paying attention to the content displayed on the screen.

[0127] Step S160: Control the first display screen to be on and display the target acquisition image through the first display screen, and store the target acquisition image.

[0128] After confirming that the target object's gaze is focused on the first display screen in the captured image, the system will activate the first display screen's lighting mechanism and display the captured image. Once the system has determined whether the target object's gaze is focused on the first display screen, the target object can view its composition in real-time on the external screen and make corresponding adjustments.

[0129] Simultaneously, the system can store the captured images of the target as part of the final shooting result. For example, during the user's video recording process, it can automatically capture images of subjects appearing in front of them and store the captured images that include the subject's frontal view.

[0130] In this embodiment, by determining whether the gaze focus of the target object in the target image is located on the first display screen when acquiring multiple frames of images, and only turning on the screen and displaying the image when the condition is met, the user's intent can be effectively identified. This allows for the execution of display operations and image storage operations as needed, thereby significantly reducing power consumption and improving the efficiency and user experience of electronic devices.

[0131] This application provides an electronic device, including a camera, a first display, a memory, and a processor. The display output area of ​​the first display is located on a first surface of the electronic device, and the lens of the camera is located on the first surface of the electronic device.

[0132] The memory stores a computer program that can run on a processor. In response to a trigger command, the processor acquires a captured image of a target area through the camera; the target area includes a target object; acquires status information of the first display screen; if the status information indicates that the first display screen is in a screen-off state, monitors the target object; if a first parameter of the target object meets the screen-on condition, controls the first display screen to be in a screen-on state and displays the captured image through the first display screen.

[0133] Figure 3CA schematic diagram of an electronic device provided in an embodiment of this application, such as... Figure 3C As shown, the electronic device includes a camera 31, a first display 32, and a first surface 33 of the electronic device, wherein...

[0134] The display output area of ​​the first display screen 32 is located on the first surface 33 of the electronic device, and the lens of the camera 31 is located on the first surface 33 of the electronic device.

[0135] In some embodiments, the electronic device may be such as Figure 2B The folding phone shown has a first surface, which is the back of the folding phone; a first display 32, which is the external screen display of the folding phone; and a camera 31, which is a rear camera located on the back of the folding phone.

[0136] For example, while a user is taking a photo using the external screen of a foldable phone, the system can obtain the status information of the external screen. If the external screen is off, the rear camera can detect the subject. If the subject's posture and the duration of their gaze on the external screen meet preset conditions, the external screen can be switched to on, displaying the captured image including the subject. In this way, the external screen of the foldable phone will only light up when the target object meets the on-screen conditions; otherwise, it remains off, avoiding the high power consumption problem caused by a constantly lit external screen in traditional solutions.

[0137] In some embodiments, the electronic device can be a candybar phone, in which case a first display 32 and a rear camera 31 are provided on the back of the candybar phone.

[0138] For example, it can be used by the user as... Figure 3C During the photo-taking process of the candybar phone shown, the status information of the external screen is obtained. If the external screen is off, the rear camera detects the subject. If the subject's posture and the duration of their gaze on the external screen meet preset conditions, the external screen can be switched to on, and the captured image including the subject is displayed on it. In this way, the external screen of the candybar phone will only light up when the target object meets the on-screen conditions; otherwise, it remains off, reducing the power consumption of the external screen.

[0139] Figure 3D This is a schematic diagram of the second surface of a rollable screen mobile phone provided in an embodiment of this application, as shown below. Figure 3D As shown, a rollable screen 34 capable of extending for display can be provided on this second surface. Figure 3E This is a schematic diagram of the first surface of a rollable screen mobile phone provided in an embodiment of this application, as shown below. Figure 3E As shown, a camera 31 and a portion of a rollable screen 34 that can be rolled up are disposed on the second surface.

[0140] For example, it can be used by the user as... Figure 3EDuring the photo-taking process of the rollable screen phone shown, the state information of the rollable screen 34 on the first surface is obtained. If the rollable screen 34 on the first surface is in a screen-off state, the rear camera 31 detects the subject. If the subject's posture and the duration of looking at the outer screen meet preset conditions, the rollable screen 34 on the first surface can be switched to a screen-on state, and the captured image including the subject can be displayed on the rollable screen 34 on the first surface. In this way, the rollable screen 34 on the first surface will only be lit when the target object meets the screen-on conditions; otherwise, it will remain screen-off, reducing the power consumption of the rollable screen 34 on the first surface.

[0141] In some embodiments, the electronic device further includes a second display screen, the first display screen and the camera are fixed to a first body of the electronic device, the second display screen is fixed to the first body and the second body of the electronic device, the display output area of ​​the first display screen and the lens of the camera are located on the first surface of the first body, and the second display screen is located on the second surface formed by the first body and the second body; the first surface and the second surface are not adjacent.

[0142] Here, the first and second bodies together constitute the main structure of the device, with the first body housing the electronic device's first display screen and camera. For example... Figure 2B As shown, the foldable phone includes a first body 21 and a second body 22. The first body 21 and the second body 22 together constitute the main structure of the foldable phone. The first body 21 houses the first display screen (outer screen) and the (rear) camera of the foldable phone, located on the first surface, i.e., on the back of the first body 21. The second body 22 can be a flip-out or sliding part. The second body 22 and the first body 22 can jointly house the second display screen (main screen), such as the main screen in the unfolded state of the foldable phone, which can provide a larger viewing area when the phone is unfolded. It is located on the second surface, i.e., on the front of the foldable phone.

[0143] The processor responds to the trigger instruction including:

[0144] If the processor detects that the first body and the second body meet the bending angle and the camera is in the acquisition state, it continuously stores the acquired images as multiple frames in a video file.

[0145] For example, such as Figure 2C As shown, the video recording function can be activated when the folding angle of the phone is approximately 90 degrees.

[0146] In this embodiment, the system determines to activate the recording function by detecting the bending angle of the device and the camera's acquisition status. This control method enables the system to intelligently identify the user's recording needs, effectively improving the user's shooting experience and extending the device's battery life.

[0147] In scenarios where the rear camera of a foldable phone is used for shooting, the external screen is turned on after the rear camera is activated. The subject can then see the overall composition of the image on the external screen and adjust the positioning themselves or guide the photographer to modify the positioning to achieve the desired photo. The drawbacks of this approach are: the external screen is always on, resulting in high power consumption; and due to the compact design of foldable phones, heat dissipation is poor, leading to noticeable overheating and a significant performance degradation during use.

[0148] In view of the above problems and the shortcomings of existing solutions, this application proposes an improvement. Figure 4A This application provides a flowchart illustrating a process for controlling the external screen of a mobile phone, as shown in the embodiments below. Figure 4A As shown, you can control the phone's external screen through the following steps:

[0149] Step S401: The camera continuously acquires images;

[0150] Here, the application scenario is for users to utilize, such as Figure 2C The camera is taken from the outer screen of the foldable phone shown, with the camera and the outer screen on the same surface.

[0151] During implementation, users can hold the foldable phone's rear camera to continuously shoot and store video frames, or continuously preview the captured footage.

[0152] Step S402: Determine whether a face has been detected;

[0153] If it is determined that there is no human face in the shooting frame, it can be determined that there is no subject who needs to view the image displayed on the external screen. Then, the following step S403 can be performed to turn off the external screen.

[0154] If it is confirmed that there is a human face in the captured image, the following steps S404 can be performed.

[0155] Step S403: Turn off the external screen;

[0156] Here, turning off the external screen can be used to set the external screen to be off.

[0157] Step S404: A face is detected after stabilizing for 3 frames;

[0158] During implementation, a frame rate threshold (e.g., 3 frames) can be preset. If the number of frames in which a face is detected in the captured image is greater than the frame rate threshold, it can be determined that there is a need for the subject to view the image displayed on the external screen. Then, step S405 is executed to open the external screen for the subject to view.

[0159] In some embodiments, the eye region can be located by analyzing facial landmark data, and it can be determined whether the eyes are looking at the camera. After the eyes have been looking at the camera for a period of time, the system can execute step S405 to automatically turn on the external screen display, providing a more natural interactive experience.

[0160] In some embodiments, user-defined screen-on gestures can be recorded in the phone settings. When the system detects a user-defined screen-on gesture, it can trigger step S405, automatically activating the external screen preview function, thereby reducing the frequency of manual operation and improving ease of use.

[0161] In some embodiments, the external screen can also be turned on using voice commands, tapping the screen, or other methods.

[0162] If the number of frames in the captured image that consistently detect a face is less than or equal to the frame number threshold, it can be determined that there is no subject who needs to view the image displayed on the external screen. Then, the following step S406 can be performed to turn off the external screen.

[0163] Step S405: Open the external screen;

[0164] Here, turning on the external screen means switching the external screen from a sleep state to a wake state.

[0165] Step S406: Turn off the external screen.

[0166] In this embodiment, a face detection algorithm is combined with intelligent recognition logic to intelligently control the on / off state of the external screen display. This technical solution fully considers the actual usage scenarios of users, effectively reducing power consumption while ensuring that the photography experience is not affected. Adopting this technical solution offers the following advantages: intelligent detection; significant power saving; and meeting users' needs for photographic quality.

[0167] Figure 4B This application provides a flowchart illustrating a process for controlling the external screen of a mobile phone, as shown in the embodiments below. Figure 4B As shown, you can control the phone's external screen through the following steps:

[0168] Step S411: The camera continuously acquires images;

[0169] Step S412: Face detected;

[0170] Step S413: Turn off the external screen;

[0171] Step S414: Determine whether the face frame is larger than the preset size;

[0172] In a facial recognition system, the Region of Interest (ROI) can be defined as the region containing a face (face bounding box). By extracting this region, the system can more accurately identify facial features, thereby improving recognition accuracy.

[0173] Here, a preset size (e.g., 40 pixels × 40 pixels) area can be determined based on requirements.

[0174] During implementation, the size of the face bounding box can be identified. If the face ROI area is too small (less than or equal to the preset size), the face is directly filtered out, that is, the face is not detected as the target object. Step S413 is executed to close the outer screen.

[0175] If the face frame is determined to be larger than the preset size, then perform the following step S415.

[0176] Step S415: Does the face pose meet the requirements?

[0177] During the process, facial posture can be used to predict whether the subject is the one being photographed. For example... Figure 3B As shown, if the yaw angle of a face is too large, that is, the closer the captured face is to the side profile, the greater the probability that the subject of the face is a passerby, and it can be filtered out, that is, not monitored as a target object.

[0178] Step S416: Stable 2-second detection;

[0179] During implementation, a time threshold can be preset (e.g., 2 seconds). If it is determined that the duration of a stable detection of a face in the shooting frame that meets the posture requirements is greater than or equal to the time threshold, it can be determined that there is a need for the subject to view the screen displayed on the external screen. Then, step S417 is executed to open the external screen for the subject to view.

[0180] If the duration of stable detection of a face in the shooting frame that meets the posture requirements is less than the duration threshold, it can be determined that there is no need for the subject to view the image displayed on the external screen. Then, step S413 is executed to turn off the external screen.

[0181] Step S417: Open the external screen.

[0182] In this embodiment, by introducing intelligent recognition logic, pedestrians (not the subject of the shot) in the shooting scene are identified and filtered, which realizes more precise dynamic control of the external screen display function, which not only improves the energy efficiency ratio of the device, but also enhances the user experience.
