Problems solved by technology

Correspondingly, different viewing distances correspond to different optimal screen display sizes. In the prior art, the screen display size of a TV cannot be adjusted. However, different screen display sizes correspond to different viewing effects at different distances. Therefore, a fixed screen display size is adopted The display effect of the picture is poor. When the distance between the viewer and the TV changes, the display picture cannot be adjusted according to the convenience of the azimuth, which will make the TV picture unclear.
In addition, for children, children who watch TV too close to the screen will be more likely to induce myopia when they stare at the screen for too long. The existing screen adjustment cannot adjust the screen size according to the distance between the user's eyes and the display screen. or brightness, so it is impossible to protect the user's eyesight, so when the user watches the display screen for a long time, it is easy to have bad conditions such as fatigue and dry eyes, and the practicability is poor. Control method and control system for screen display based on distance between screens

Embodiment 1

[0052] like figure 1 As shown, Embodiment 1 of the present invention provides a control method for screen display. The method detects the distance between the user's face and the display screen, adjusts the size of the video in the display screen, and effectively protects the user's eyes. The method includes the following steps:

[0053] S1. A camera 1 for capturing front-end images of the display screen is installed on the display screen. The camera 1 is used to capture images, and the camera 1 is used as an image input device to obtain image information facing the display screen through the camera 1.

[0054] S2. Determine whether the display screen is in the on state. If the display screen is not in the on state, then no adjustment is needed. If it is in the on state, start the camera 1 to take images.

[0055] S3. Perform face recognition on the captured image. Face recognition is to recognize facial features in the image, such as eyes, mouth, nose, etc. If there is a hum...

Embodiment 2

[0061] Embodiment 2 of the present invention further defines the control method on the basis of Embodiment 1.

[0062] It should be further noted that, in step S3, in order to effectively recognize the human face and at the same time determine whether the user in the shooting area is in the state of watching the display screen, the technical solution limits the face recognition of the captured image , if there is a human face, then detect the distance value between the human face and the display screen, which specifically includes the following steps:

[0063] S3-1. Remove noise and background areas with small areas in the captured image to obtain an image part;

[0064] S3-2. Judging whether there is a human face image in the processed image, you only need to judge whether there are human face features in the image, such as eyes, nose, mouth, etc., you can judge whether there is a human face image, you can judge the user In front of the display screen; if there is a human fa...

Embodiment 3

[0101]The present invention also provides a control system for screen display, including a camera 1 installed on the display screen, a state monitoring module 2, a face recognition module 3, a measurement module 4, an attribute acquisition module 5, a comparison module 6, and a judgment module 7 And attribute adjustment module 8;

[0102] The state monitoring module 2 is connected with the camera 1, and it is used to judge whether the display screen is in an open state, and if it is in an open state, an instruction to start the camera 1 to capture images is sent to the camera 1; The face recognition module 3 is used to perform face recognition on the captured image, and if there is a human face, then send a measurement instruction to the measurement module 4, and the measurement module 4 is used to measure the distance between the human face and the display screen. The distance value between them is sent to the comparison module 6 or the judgment module 7; the attribute acquis...

Abstract

The invention provides a control method and control system for screen display. The method comprises: starting the camera to take images; performing face recognition on the captured images, and measuring the distance between the face and the display screen; Video attribute, preset distance threshold; if the distance value is less than the preset distance threshold, quickly generate a reminder message and display it to the user in the form of a pop-up window, record the time node T1 when the pop-up window jumps out; take time node T1 as the starting point , within the preset time period △T, measure the distance value between the face and the display screen again, if the distance value is still less than the distance threshold within the preset time period △T, then adjust the video played on the display screen Attributes. The invention adjusts the video display size and audio size according to the distance between the user and the display screen, effectively protects the user's eyes, keeps the user's viewing experience in the best state, protects the user's eyesight, and has strong practicability.

Description

technical field [0001] The invention relates to the technical field of screen display, in particular to a control method and system for screen display. Background technique [0002] At present, as various terminal devices with screens become more and more popular, various applications and services in terminal devices are becoming more and more abundant. People are more and more likely to use terminal devices in their daily life or work. People use The time of the terminal equipment is getting longer and longer, therefore, users have higher and higher requirements for browsing the comfort of the terminal equipment. [0003] For example, when a user watches TV, different screen display sizes correspond to different optimal viewing distances. Correspondingly, different viewing distances correspond to different optimal screen display sizes. In the prior art, the screen display size of a TV cannot be adjusted. However, different screen display sizes correspond to different viewi...
