[0002] With the development of mobile terminal technology, electronic devices have become more and more important in users' daily lives. For example, users can watch various information such as animations, videos, and images through electronic devices.

[0003] However, most electronic devices currently do not have a shock absorption function, and the display screens of electronic devices are generally small. If a user uses an electronic device to read text or small image details while walking or on a bumpy vehicle, if the electronic device has a large shake, the text or image details on the screen will be in a shaking state at the same time, and the user's eyes will be constantly in the process of focusing and adjusting, which can easily cause eye fatigue, resulting in a poor user experience and is not conducive to the user's eyesight protection.

[0061] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the specific technical solution of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0062] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0063] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be 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.

[0064] It should be pointed out that the terms "first\second\third" involved in the embodiments of the present application are used to distinguish similar or different objects, and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0065] An embodiment of the present application provides a screen anti-shake method, which is applied to an electronic device. Figure 1 FIG. 1 is an application scenario diagram of a screen anti-shake method provided in an embodiment. Figure 1As shown, the user can carry, wear or use an electronic device 10, which may include but is not limited to a mobile phone, a wearable device (such as a smart watch, a smart bracelet, smart glasses, etc.), a tablet computer, a laptop computer, a vehicle terminal, a PC (Personal Computer), etc. The electronic device includes a screen and a support, and the screen is rotatably connected to the support. The function implemented by the method can be implemented by calling a program code by a processor in the electronic device, and of course the program code can be stored in a computer storage medium. It can be seen that the electronic device at least includes a processor and a storage medium.

[0066] In the embodiment of the present application, the electronic device 10 may include at least a screen 20 and a support 30, and the screen 20 is rotatably connected to the support 30. Optionally, the electronic device 10 may also include a processor, a power supply, a mechanical hinge, a front camera, a touch screen, a motion sensor, and a wireless connection module.

[0067] Figure 2 The following is a schematic diagram of the implementation process of the screen anti-shake method provided in the embodiment of the present application. Figure 2 As shown, the method may include the following steps 201 to 203:

[0068] Step 201 : when the screen of the electronic device outputs a picture, a target pattern is obtained, where the target pattern is used to indicate the relative position relationship between the user's face and a preset direction of the screen.

[0069] It is understandable that users often use electronic devices to view output images while walking or taking public transportation. In this case, the screen of the electronic device may shake slightly, which in turn causes the output image on the screen to shake, making it impossible for the user's line of sight to be completely in a relatively stable state with the output image, affecting the user's viewing.

[0070] In the embodiments of the present application, Figure 3 As shown, when the screen of the electronic device outputs a picture, a target pattern can be captured by the front camera 40 on the electronic device, and the target pattern can represent the relative position relationship between the user's face and the preset direction of the screen.

[0071] Optionally, the preset direction may be the center of the screen, and the target pattern may indicate whether the user's face is in relative position to the center of the screen, that is, the target pattern may indicate whether the user's face is facing the center of the screen of the electronic device.

[0072] Optionally, the preset direction may also be the user's preferred direction, that is, the viewing angle of the user when viewing the output screen in the past. For example, if the user likes to view the output screen with his head tilted to the left side of the screen, the target pattern may indicate the relative position relationship between the user's face and the left side of the screen, that is, the target pattern may indicate whether the user's face is facing the left side of the screen of the electronic device.

[0073] In the embodiment of the present application, there is no limit on the number of target patterns obtained, for example, the target pattern may be a single frame pattern or a multi-frame pattern. The target pattern may be an image containing the user's face or a polygon projected onto the screen, which is not limited in the embodiment of the present application.

[0074] Step 202: Determine whether the user's face is offset from a preset direction based on the target pattern and a pre-stored comparison pattern.

[0075] In an embodiment of the present application, the pre-stored comparison pattern corresponds to the target pattern. For example, if the target pattern is a polygonal pattern, the comparison pattern is also a polygonal pattern; if the target pattern is a face pattern, the comparison pattern is also a face pattern; if the target pattern is a text pattern, the comparison pattern is also the same text pattern.

[0076] Optionally, the position of the contrast pattern can be at the center of the screen, then determining whether the user's face is offset from the preset direction, that is, determining whether the user's face is located at the center of the screen; the position of the contrast pattern can also be set at the user's preferred viewing position, such as setting it on the left side of the screen, then determining whether the user's face is offset from the preset direction, that is, determining whether the user's face is located on the left side of the screen.

[0077] In some embodiments, when determining whether the user's face is offset from a preset direction based on a target pattern and a pre-stored comparison pattern, it can be achieved by executing steps 403 to 404 in the following embodiments.

[0078] Step 203, when it is determined that the user's face is offset from the preset direction, adjust the presentation angle of the screen of the electronic device to obtain a corrected electronic device, wherein the first offset degree is greater than the second offset degree, the first offset degree is the offset degree between the user's face and the preset direction of the screen of the electronic device before correction, and the second offset degree is the offset degree between the user's face and the preset direction of the screen of the electronic device after correction.

[0079] In some embodiments, to adjust the presentation angle of the screen of the electronic device, it can be achieved by executing steps 404 to 405 in the following embodiments.

[0080] The electronic device in the embodiment of the present application includes a screen and a support member, such as Figure 1As shown, when adjusting the display angle of the screen of the electronic device, the screen can be controlled to rotate around the support member so that the offset between the user's face and the preset direction is reduced from the first offset to the second offset, that is, the screen of the electronic device after adjustment is kept facing the user's face.

[0081] In the embodiment of the present application, when the screen of the electronic device outputs a picture, a target pattern is obtained, and the target pattern is used to indicate the relative position relationship between the user's face and the preset direction of the screen; according to the target pattern and the pre-stored contrast pattern, it is determined whether the user's face and the preset direction are offset; if offset occurs, the presentation angle of the screen of the electronic device is adjusted to obtain a corrected electronic device, and the offset degree between the user's face and the preset direction of the screen of the electronic device before correction is greater than the offset degree between the user's face and the preset direction of the screen of the corrected electronic device. In this way, the screen jitter of the electronic device can be quickly adjusted, thereby improving the viewing stability of the user and protecting the user's eyesight.

[0082] Figure 4 The following is a schematic diagram of the implementation process of the screen anti-shake method provided in the embodiment of the present application. Figure 4 As shown, the method may include the following steps 401 to 405:

[0083] Step 401, determining whether the user is in a jittery environment.

[0084] It is understandable that when the user is in a stationary state, the electronic device he is using is generally also in a stationary state, and the output image of the electronic device screen does not jitter, which is convenient for the user to watch. However, users often use electronic devices to watch output images while walking or taking public transportation. In this case, the screen of the electronic device may have slight jitters, which in turn causes the output image of the screen to jitter, making it impossible for the user's line of sight to be completely in a relatively stable state with the output image, affecting the user's viewing.

[0085] Therefore, in an embodiment of the present application, it is necessary to determine whether the user is in a jittery environment so as to correct the screen of the electronic device when the user is in a jittery environment to improve the user's viewing stability.

[0086] In some embodiments, Figure 6 As shown, the user can wear a wearable device, which can be a wireless headset, a headset, a VR device, etc. The electronic device is provided with a first motion sensor, and the wearable device is provided with a second motion sensor. Based on this, in order to determine whether the user is in a shaking environment, the following steps 501 to 503 can be performed:

[0087] Step 501: collect a motion signal of a target device through a motion sensor, where the motion sensor includes a first motion sensor and / or a second motion sensor, and the target device includes an electronic device and / or a wearable device.

[0088] Understandably, if a user uses a wearable device and an electronic device at the same time, the wearable device may shake while the electronic device does not. For example, when a user shakes his head to the rhythm of a song, the headphones may shake, but the phone does not move. Alternatively, the wearable device may not move while the electronic device may shake, for example, when a user stands still but shakes the phone left and right. Alternatively, the wearable device and the electronic device may shake at the same time.

[0089] Based on this, in an embodiment of the present application, a motion signal of an electronic device can be collected by a first motion sensor, and / or a motion signal of a wearable device can be collected by a second motion sensor, so as to determine whether the user is in a shaking environment based on the collected motion signals of one or both devices.

[0090] Step 502: Determine the vibration amplitude of the target device according to the motion signal.

[0091] It should be noted that if a user wears or carries an electronic device and / or wearable device to engage in extensive exercise such as running or playing ball, it is generally not necessary to correct the screen of the electronic device in order to improve the user's viewing stability.

[0092] Therefore, in an embodiment of the present application, after the motion signal of the electronic device and / or the wearable device is obtained, the corresponding jitter amplitude of the electronic device and / or the wearable device can be determined to determine whether the user is in a jittering environment, and whether the jittering environment is gentle or severe based on the jitter amplitude.

[0093] Step 503: When the shaking amplitude is less than the threshold, determine whether the user is in a shaking environment.

[0094] Here, there is no limitation on the setting of the threshold value, and the threshold value can be set according to actual needs. When the jitter amplitude of the electronic device and / or the wearable device is small, it can be determined that the user is in a relatively gentle jitter environment. In this environment, the screen of the electronic device can be corrected to improve the viewing stability of the user.

[0095] Step 402, when the user is in a shaking environment and the screen of the electronic device outputs a picture, a target pattern is obtained, where the target pattern is used to indicate the relative position relationship between the user's face and a preset direction of the screen.

[0096] Here, the method of acquiring the target pattern is the same as that in step 201 in the above embodiment, and will not be repeated here.

[0097] Step 403, based on the multiple-frame target patterns, determine whether the user is in a state of looking at the screen within a preset time length, wherein if the first target pattern includes at least a portion of the user's facial area, it means that the user is in a state of looking at the screen at the moment of acquiring the first target pattern, and the first target pattern is any frame pattern in the multiple-frame target patterns.

[0098] It is understandable that if a user randomly glances at the screen of an electronic device, it does not mean that the user has the intention to watch the output picture presented on the screen of the electronic device. At this time, if after obtaining a frame of target pattern, that is, after obtaining a frame of pattern of the user's face presented on the screen, the screen is corrected based on the target pattern, it may cause unnecessary power consumption.

[0099] Therefore, in some embodiments, the screen of the electronic device is corrected only after it is determined that the user has been looking at the screen of the electronic device for a period of time, that is, when it is determined that the user has the intention to watch the output image presented on the screen of the electronic device. This can avoid unnecessary power consumption caused by frequently correcting the screen angle of the electronic device.

[0100] Of course, in some embodiments, the user can also choose to set the electronic device to not judge whether the user is looking at the screen within a preset time when a frame of target pattern is acquired, that is, to perform screen correction based on the acquired frame of target pattern.

[0101] Optionally, when determining, based on the multi-frame target patterns, whether the user is in a state of looking at the screen within a preset time period, multiple methods may be included.

[0102] For example, in some embodiments, the electronic device is provided with a camera, and the acquired multi-frame target pattern is a pattern including the user's facial area acquired by the camera. When determining whether the user is looking at the screen within a preset time period based on the multi-frame target pattern, it is possible to determine whether the user is in a state of looking at the screen within the preset time period based on the completeness of the presentation of the user's face recognized in each frame of the target pattern acquired within the preset time period.

[0103] In other embodiments, Figure 6 As shown, the user wears a wearable device, and a plurality of projection units 60 are provided in the wearable device. If the first target pattern includes at least one projection unit, it means that the first target pattern includes at least a part of the user's facial area.

[0104] In some embodiments, the wearable device may also include a processor, a power supply, a microphone, a speaker, and a wireless connection module.

[0105] Specifically, each projection unit of the wearable device can emit light spots. In this way, when the user wears the wearable device, if he faces the screen of the electronic device, the front camera of the electronic device can capture the first target pattern formed by the light spots emitted by the emitting unit. When the first target pattern includes at least one light spot, it can indicate that the first target pattern includes at least part of the user's facial area.

[0106] Based on this, step 403 can be implemented by executing the following steps 701 to 702:

[0107] Step 701 : Determine whether there are at least two frames of third target patterns in multiple frames of target patterns, the at least two frames of third target patterns are acquired within a preset time length, and each frame of the third target pattern includes at least one projection unit.

[0108] Step 702: If yes, determine that the user is in a state of looking at the screen within a preset time period.

[0109] Here, when at least two consecutive target pattern frames include at least one projection unit, it can be explained that the user's face continues to face the screen of the electronic device, thereby indicating that the user is in a state of staring at the screen within the preset time length.

[0110] In addition, the embodiment of the present application does not limit the method for determining whether the target pattern includes at least part of the user's facial area. For example, the front camera of the electronic device can directly capture the user's facial image for recognition to determine whether the target pattern includes at least part of the user's facial area; or, it can be determined by the number of projection units captured by the camera. When at least one projection unit is captured, it can be considered that the target pattern includes at least part of the user's facial area.

[0111] Step 404: determining a first deviation degree of the user's face from a preset direction according to a second target pattern in the multi-frame target pattern and a pre-stored comparison pattern, wherein the second target pattern is the last frame pattern in the multi-frame target pattern.

[0112] Here, after determining that the user is looking at the screen for a preset time period based on the multi-frame target pattern, the screen of the electronic device can be corrected based on the last frame pattern (ie, the second target pattern) in the collected multi-frame target pattern.

[0113] When the screen of the electronic device is corrected based on the second target pattern and the contrast pattern, the first offset degree between the user's face and the screen of the electronic device needs to be known first, so as to perform correction according to the first offset degree.

[0114] In the embodiment of the present application, there is no limitation on the method for determining the first degree of offset between the user's face and the preset direction of the screen.

[0115] For example, in some embodiments, a user wears a wearable device, a plurality of projection units are arranged in the wearable device, the target pattern includes the plurality of projection units, the contrast pattern is a polygonal pattern composed of the plurality of projection units, and the first offset degree includes a target offset direction and a first offset angle.

[0116] Based on this, step 404 can be implemented by executing steps 801 to 804 in the following embodiment:

[0117] Step 801 : acquiring first center position coordinates of the target pattern according to a plurality of projection units in the target pattern, and acquiring second center position coordinates of the contrast pattern according to a polygonal pattern in the contrast pattern.

[0118] like Fig. 9 As shown, assuming that the contrast pattern 90 is a polygonal pattern and the target pattern 91 is also a polygonal pattern, the first center position coordinate C1 of the target pattern can be determined first, and the second center position coordinate C2 of the contrast pattern can be determined.

[0119] Step 802: Determine a target offset direction between the user's face and a preset direction according to a positional relationship between the first center position coordinates and the second center position coordinates.

[0120] After determining the first center position coordinate C1 and the second center position coordinate C2, the target offset direction between the user's face and the preset direction can be determined, such as Fig. 9 As shown, the target offset direction is to the left.

[0121] Step 803: Obtain a first side length ratio of the target pattern and a second side length ratio of the comparison pattern.

[0122] Here, the first side length ratio is the length ratio of each side length of the target pattern, and the second side length ratio is the length ratio of each side length of the comparison pattern.

[0123] Step 804: Determine a target offset angle between the user's face and a preset direction according to the first side length ratio and the second side length ratio.

[0124] By implementing the above method, the target offset direction and target offset angle between the user's face and the preset direction can be obtained.

[0125] Step 405: adjust the presentation angle of the screen of the electronic device according to the first offset degree.

[0126] In some embodiments, Fig.10As shown, after obtaining the target offset direction and target offset angle, the screen can be controlled to rotate around the support according to the target offset angle and target offset direction, so as to adjust the presentation angle of the screen of the electronic device so that the offset degree between the user's face and the preset direction is reduced from the first offset degree to the second offset degree.

[0127] Furthermore, the electronic device may also include a mechanical shaft, and the electronic device may control the mechanical shaft to rotate according to the target offset angle and the target offset direction to adjust the presentation angle of the screen of the electronic device.

[0128] In other embodiments, the degree of deviation between the user's face and the preset direction may not be specifically determined. Instead, when it is determined that the user's face is offset from the preset direction, the screen of the electronic device may be adjusted, as shown in steps 1101 to 1102 in the following embodiment:

[0129] Step 1101, when it is determined that the user's face is offset from a preset direction, determine the offset direction of the user's face from the preset direction.

[0130] Here, when it is determined that the user's face is offset from a preset direction, only the relative offset direction between the user's face and the center position of the screen or the preset position may be determined.

[0131] Step 1102: adjusting the presentation angle of the screen of the electronic device according to the offset direction and a preset adjustment angle.

[0132] It should be noted that the preset adjustment angle may be a fixed angle. For example, if it is determined that the user's face is offset to the left relative to the preset direction, the angle may be adjusted to the right by 5 degrees.

[0133] Here, when adjusting the presentation angle of the screen of the electronic device, the electronic device may also control the mechanical shaft to rotate according to the offset direction and the preset adjustment angle to adjust the presentation angle of the screen of the electronic device.

[0134] In an embodiment of the present application, it is provided to determine whether the user is in a jittery environment. When the user is in a jittery environment and the screen of the electronic device outputs a picture, a target pattern is obtained, and the target pattern is used to indicate the relative position relationship between the user's face and the preset direction of the screen; according to the multi-frame target pattern, it is determined whether the user is in a state of looking at the screen within a preset time length, and if so, the first offset degree of the user's face and the preset direction is determined according to the last frame pattern in the multi-frame target pattern and the pre-stored comparison pattern, and finally the presentation angle of the screen of the electronic device is adjusted according to the first offset degree. In this way, the screen jitter of the electronic device can be quickly adjusted, thereby improving the viewing stability of the user and protecting the user's eyesight.
