Embodiment 1

[0026] Referring to Fig. 1-Fig. 3, a method for automatically adjusting the screen display size according to the present invention is characterized in that it includes the following steps:

[0027] S1. A distance sensing device is set on the display 1, and the distance sensing device is used to detect the distance between the human body and the display screen.

[0028] In the field of automation, it is a very common technology to use sensors to detect distances. Commonly used distance detection sensors include infrared distance detectors, ultrasonic distance detectors, and laser distance detectors. In order to minimize the impact on the human body, the preferred It is an infrared distance detector 12, which is arranged above the display, and the end face of the sensor is substantially on the same plane as the screen of the display 11 .

[0029] S2. Set the correspondence table between the distance from the human body to the display screen and the screen display ratio in server...

Embodiment 2

[0039] The difference between this embodiment and Embodiment 1 is that the distance sensing device in this embodiment is a camera, which can be installed externally, or can use the built-in camera 14 of the display. In order to realize the detection of the distance between the human body and the display screen, Image processing software needs to be set in the server 2 to analyze the images acquired by the camera 14, and calculate the distance between the human body and the display screen according to the analysis results. A specific method is disclosed below:

[0040] S31. When someone approaches, the camera 14 takes pictures;

[0041] S32, server 2 performs face recognition based on the picture obtained in step S31;

[0042] S33. The server 2 calculates the ratio of human face pixels to the total pixels of the current picture;

[0043] S34. Calculate the distance between the human body and the display screen according to the ratio obtained in step S33.

[0044] Of course, f...

Abstract

The invention relates to a method for automatically adjusting the screen display size. The method comprises the following steps: setting a distance sensing device, and presetting condition data of a display scale, and detecting the distance between the human body and the display screen and adjusting the display size of the screen. According to the method, the distance sensing device is arranged onthe display, so that a computer can enlarge or reduce the display size of a screen according to the distance between a human body and the display screen, on one hand, children can be helped to form good watching habits, and myopia of children is prevented to a certain extent; and on the other hand, the display size can be amplified on the basis of normal display to assist the elderly in watching.

Description

technical field [0001] The present invention relates to a self-adaptive screen adjustment method, in particular to a method for automatically adjusting the display size of the screen. Background technique [0002] In modern society, the popularity of computers has brought great convenience to people's work and life, and it has also brought people a habit: to spend a lot of time in front of the computer screen. The time will be more than 6 hours. This habit has seriously affected people's vision. And for children, some incorrect usage habits of children, such as eyes being too close to the screen, staring at the screen for too long, etc., can more easily induce myopia. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a method for automatically adjusting the display size of the screen, which can help children develop good viewing habits and prevent children from myopia to a certain extent. ...
