At present, most display screens (such as televisions) on the market achieve the protection of the eyesight of viewers by optimizing luminous sources. For example, blue light filtering technology is added to the screen of a television to reduce the harm of harmful blue light sources to the eyes of viewers; screenless projection televisions are designed so that the light from the projector is reflected and presented to the viewer to reduce the harm of direct light.

Although the product can also play a role in protecting eyesight to a certain extent, the product cannot help viewers, especially children, to develop good eye habits, and the product is often high in manufacturing cost, so that the effect is generally poor.

Therefore, an embodiment according to the present disclosure provides a screen display adjustment method 200, as shown in fig. 2, including: identifying a user viewing the screen in response to the screen being played (step 210); in response to determining that the user is a target user, obtaining viewing characteristics of the target user while viewing the screen (step 220); and adjusting the display content of the screen play based on the viewing characteristics (step 230).

According to the embodiment of the disclosure, the watching characteristics of a specific crowd watching a screen can be identified, so that the display content of the screen is adjusted based on the watching characteristics, education is guided, a user is helped to develop good eye using habits, and the effect of protecting eyesight is achieved.

At step 210, in response to the screen being played, a user viewing the screen is identified.

According to some embodiments, as shown in fig. 3, step 210 may further include: acquiring an image of the front end of a screen (step 310); performing face recognition on the image based on the face recognition model to recognize a user at the front end of the screen (step 320); and determining whether the identified user is a target user (step 330).

According to some embodiments, acquiring the image of the front end of the screen comprises: acquiring a video stream of a front-end picture of a screen through a camera device; and capturing the video stream at intervals of a preset time period to obtain an image at the front end of the screen.

Illustratively, the camera device may be various types of cameras, video cameras, etc. for acquiring a video stream at the front end of the screen. It is understood that the front end of the screen is an active area where the user views the content played on the screen, and includes possible areas directly in front of the screen, left front, right front, upper front, lower front, and the like, which is not limited herein.

In some examples, the image of the front end of the screen may also be acquired every predetermined period of time by an image acquisition device such as a camera, a vision sensor, or the like. For example, the captured video stream may be captured every 3 seconds or an image of the front end of the screen may be captured every 3 seconds for face recognition based on the captured image.

In some examples, after the image of the front end of the screen is acquired, the acquired image of the front end of the screen may be subjected to face recognition by a trained face recognition model to identify one or more users who are viewing the screen and determine whether the identified users are target users. According to some embodiments, the target user may be a child. Determining whether the identified user is the target user may include: acquiring an age attribute of the identified user based on the face recognition model; and in response to the age attribute of the user not exceeding the preset age, determining the identified user as the target user.

Through the face recognition model, not only can the user contained in the image be recognized, but also various face attribute information can be accurately recognized. In this embodiment, it may be determined whether the identified user is the target user based on the age attribute.

In some examples, a face in an image may be detected by face recognition techniques and a particular age value of the face may be tagged. For example, a child may be considered to be no older than 15 years of age. When the age of the identified user is 13 years by the face recognition mark, the user can be determined as the target user.

In some examples, a face in an image may be detected by face recognition techniques and an age classification of the face may be labeled. For example, the age categories may include categories of "young child", "young age", "middle age", "old age", and the like. For example, when the identified user is a "baby" or a "teenager" through the face recognition mark, the user may be determined to be the target user.

It is understood that whether the identified user is the target user may also be determined by other face attribute information, including but not limited to, gender, head pose, whether to close eyes, whether to wear glasses, and the like.

In

steps

220 and 230, in response to determining that the user is the target user, the viewing characteristics of the target user when viewing the screen are obtained, and the display content played by the screen is adjusted based on the viewing characteristics.

After the identified user is determined to be the target user, the watching characteristics of the user are further acquired, so that not only can the computing resources be saved, but also the effect of quickly adjusting the display content played on the screen can be realized, and the requirement of protecting eyesight is met.

According to some embodiments, the viewing features may include pose features. Accordingly, the pose features of the target user while viewing the screen may be identified based on the trained model. For example, the model may be based on a human body key point recognition technology to detect the human body of the target user in the image and return to the position of the human body rectangular frame, and accurately locate the core key points including the vertex, the five sense organs, the neck, the main joint parts of the four limbs, and the like, so as to accurately recognize the posture characteristics of the target user.

In some embodiments, the human body key point identification can be continuously carried out on the acquired image at the front end of the screen; or an image or video stream including the target user can be further acquired, so that human body key point recognition is carried out to recognize the posture characteristic of the target user.

In some embodiments, the gesture features can be divided into a gesture class that is not conducive to vision protection and a gesture class that is conducive to vision health, such that the display content played on the screen can be further adjusted based on the recognized gesture features.

According to some embodiments, the pose features may include: lying, lying or sitting, etc. It can be understood that the lying position and the lying position are not beneficial to eyesight protection, and the sitting position is beneficial to eyesight health. Accordingly, adjusting the display content of the screen based on the viewing characteristics includes: prompting on a screen in response to the viewing characteristic of the target user being identified as a recumbent or prone position; and in response to the viewing characteristic of the target user adjusting to a sitting position, the prompt disappears.

In some examples, after the viewing characteristics of the target user are identified as lying or prone, the playing of the screen may also be paused and prompted on the screen; and after the target user adjusts the viewing characteristic from the lying or prone position to the sitting position, the prompt disappears and the playback of the screen resumes.

Illustratively, FIG. 4 shows a schematic diagram of a screen display when the viewing characteristics of the target user are identified as being in a lying position. If the recognition result is the lying posture/prone posture, immediately pausing the playing of the screen, prompting in a full screen mode, informing a user that the lying posture/prone posture is easy to damage eyesight, and asking for timely adjustment; if the user does not continuously adjust, continuously prompting and failing to normally play the video; and if the user adjusts, reminding to disappear and resuming the normal playing.

It should be understood that other ways of prompting are possible, including but not limited to displaying the prompting content in a pop-up manner. Illustratively, a pop-up window pops up on the play interface of the screen to indicate that the current pose is impaired vision.

According to some embodiments, the viewing feature may comprise a distance feature. Accordingly, obtaining the viewing characteristics of the target user when viewing the screen may include: and acquiring the distance between the target user and the screen.

According to some embodiments, the distance of the target user from the screen may be acquired by a distance sensor. For example, a distance sensor may be provided within or near the screen to indicate where the screen is located. After the user is identified as the target user through face identification, the distance between the screen and the target user can be acquired in real time through the distance sensor, and the target user is dynamically reminded based on the distance. The distance sensor may include, but is not limited to, an infrared ranging sensor, an ultrasonic sensor, or a laser ranging sensor, etc.

According to some embodiments, obtaining the distance of the target user from the screen may include: acquiring an image containing a target user at the front end of the screen through a camera device; and acquiring the distance between the user and the camera device based on the image to serve as the distance between the target user and the screen.

In some examples, the distance of portrait capture may be identified based on computer vision, including but not limited to image-based triangulation methods, binocular disparity methods, and the like.

According to some embodiments, adjusting the display content of the screen based on the viewing characteristics comprises: responding to the acquired distance being smaller than the preset distance, and prompting on a screen; and in response to the adjusted distance of the target user not being less than the predetermined distance, the prompt disappears.

In some examples, adjusting the display content of the screen based on the viewing characteristics includes: in response to the acquired distance being less than the predetermined distance, pausing the playing of the screen and prompting on the screen; and prompting to disappear and resuming the playing of the screen in response to the adjusted distance of the target user not being less than the preset distance.

In some examples, when the target user is less than a predetermined distance (e.g., 2 meters) from the screen, it is indicated that the user is too close to the display screen and is liable to damage the user's vision, thus pausing the playback of the screen and prompting on the screen with text. In the prompting process, not only can prompt sentences be displayed on the screen, but also the acquired distance between the target user and the screen can be displayed on the screen in real time, so that the distance adjustment of the user is facilitated. And prompting to disappear and resuming the playing of the screen until the distance between the user and the screen is not less than the preset distance.

Therefore, in the embodiment of acquiring the front-end image of the screen by the camera device and further acquiring the distance between the target user and the screen, the image can be acquired once every preset time, and the acquired distance data can be displayed on the screen in real time, so that the user can adjust the distance between the user and the screen based on the displayed distance data.

It should be understood that other ways of prompting are possible, including but not limited to displaying the prompting content in a pop-up manner. Illustratively, a pop-up window pops up on the play interface of the screen to indicate that the current distance is too close and vision is impaired.

According to some embodiments, the viewing characteristics may include environmental characteristics. The light intensity of the current environment can be acquired by the light sensor.

According to some embodiments, adjusting the display content of the screen based on the viewing characteristics comprises: responding to the light intensity smaller than the preset light intensity, and prompting on a screen; and prompting disappearance in response to the adjusted light intensity of the target user not being less than the predetermined light intensity.

In some examples, in response to the light intensity being less than a predetermined light intensity, the playing of the screen may be paused and prompted on the screen; and prompting to disappear and resuming the playing of the screen in response to the light intensity adjusted by the target user not being less than the preset light intensity.

Illustratively, after the target user is identified, the current ambient light level is acquired by an ambient light sensor. When the light sensor measures that the ambient light intensity is less than the eye protection red line (for example, 300LUX), pausing the screen playing and prompting that the light is too dark on the screen; meanwhile, the real-time environment light brightness can be displayed on the screen interface. The user can increase the ambient light brightness by turning on the indoor light, and when the ambient light brightness is adjusted to be higher than the eye-protecting red line, the prompt disappears and the screen playing is resumed.

It should be understood that other ways of prompting are possible, including but not limited to displaying the prompting content in a pop-up manner. Illustratively, a pop-up window is popped up on the play interface of the screen to indicate that the current ambient light is too dark and vision is impaired.

In some embodiments, the viewing characteristics may include a plurality of the above characteristics, for example, when the viewing characteristics include a posture characteristic and a distance characteristic, the distance from the screen to the target user may be first acquired, and when the acquired distance is not less than a predetermined distance, the posture characteristic of the target user may be further acquired to further determine whether to adjust the display content of the screen based on the acquired posture characteristic. It is understood that, of course, it is also possible to first obtain the posture feature of the target user, and then further obtain the distance feature of the target user when the posture feature meets the requirement of eyesight protection, and the method is not limited herein.

Of course, the viewing characteristics include both the posture characteristics and the environment characteristics, or both the environment characteristics and the distance characteristics, or the posture characteristics, the environment characteristics, and the distance characteristics, as described above, and the determination sequence thereof may also be customized according to actual requirements, which is not described herein again.
