Problems solved by technology

However, both of these two operation methods require additional input to control the display effect, so that when the user does not want to perform additional input operations, the display effect of the screen image cannot be controlled according to the distance between the display screen and the user, resulting in poor user experience

Embodiment Construction

[0027] figure 1 A flow chart of a screen image display control method according to an embodiment of the present invention is shown.

[0028] As shown in Fig. 1, first, in step S110, the distance between the display screen of the display device and the user is measured in real time. For example, the distance between the display screen of the display device and the user can be measured in real time by using a distance measuring sensor or a front camera arranged in the display device.

[0029] In the case of using a distance measuring sensor, for example, the time t1 when the ultrasonic wave emitted by the distance measuring sensor can be used and the time t2 when the distance measuring sensor receives the ultrasonic wave reflected back after reaching the user can be used to calculate the time difference Δt between the two =t2-t1. Then, the speed of sound is multiplied by the time difference and divided by 2 to obtain the distance between the display screen and the user.

Abstract

The invention provides a method for controlling screen display frames, comprising the following steps: measuring the distance between a display screen of display equipment and the user in real time; and automatically adjusting the sizes of the display frames on the display screen according to the variation of the measured distance. By the method, the sizes of the screen display frames can be automatically adjusted based on the distance between the display screen and the user under the condition that extra input is unnecessary to be carried out by the user, thus enhancing user experience.

Description

technical field [0001] The present invention relates to the field of screen image display, and more specifically, to a screen display image control method and device based on the distance between a display screen and a user. Background technique [0002] With the progress of society and the development of technology, people increasingly use computers or mobile terminals for work, such as using computers or mobile terminals to read documents or browse web page information on the Internet. When reading documents or browsing webpage information, in order to make the user’s document reading or webpage information browsing comfortable, as the distance between the user and the display screen of the computer or mobile terminal changes, it is necessary to adjust the size of the display screen on the display screen accordingly. For example, when the distance between the user and the display screen of the computer or mobile terminal becomes larger, the display picture on the display s...
