Embodiment 1

[0027] see Figure 1-Figure 3 , a method for automatically adjusting the screen display size according to the present invention is characterized in that it comprises the following steps:

[0028] 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.

[0029] 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.

[0030] S2. Setting the correspondence table between the distance from the human body to the display screen and the screen display ratio in the ...

Embodiment 2

[0040] 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 utilize 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:

[0041] S31. When someone approaches, the camera 14 takes pictures;

[0042] S32, server 2 carries out facial recognition based on the picture obtained in step S31;

[0043] S33. The server 2 calculates the ratio of human face pixels to the total pixels of the current picture;

[0044] S34. Calculate the distance between the human body and the display screen according to the ratio obtained in step S33.

[0045] Of ...

Abstract

The invention relates to a method for automatically adjusting the display size of a screen. The method comprises the following steps of: setting a distance-sensing device; presetting condition data of a display scale; detecting the distance between a human body and the screen of a display; adjusting the display size of the screen; and the like. According to the method, the distance-sensing device is arranged on the display, so that the display size of the screen can be zoomed in or zoomed out according to the distance between the human body and the screen of the display by a computer; on one hand, the method can be used for helping children form good viewing habits, so that the children are prevented from myopia to a certain degree; and one the other hand, the display size can also be zoomed in on the basis of normal display to assist in the viewing of old people.

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, and this habit has seriously affected people's vision. For children, some incorrect usage habits of children, such as keeping the eyes too close to the screen, staring at the screen for too long, etc., will 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 ex...
