Problems solved by technology

Existing user terminals, especially portable user terminals, have relatively small display screens. For poor eyesight such as myopia, presbyopia, or amblyopia, or when it is necessary to browse and observe text, pictures, and videos on the display screen in detail, the It is not convenient to observe the screen of the display screen
In practical applications, two fingers are usually used to touch the display screen at the same time and perform a reverse sliding operation to realize the enlargement of the display screen. This method requires the user to use two fingers at the same time, which invisibly improves the display screen. Display screen adjustment threshold

Embodiment approach

[0110] The generation module 4052 is further configured to generate a zoom-out operation instruction when the recognition module 4051 recognizes that the type of the rotation direction is counterclockwise;

[0111] The obtaining module 4053 is also used to respond to the reduction operation instruction and obtain the preset coefficient bound to the numerical range to which the area ratio value belongs as the reduction coefficient;

[0112] The processing module 4054 is further configured to reduce the size of the display screen of the display screen according to the reduction factor.

[0113] In the embodiment of the present invention, the user terminal may set multiple non-overlapping numerical ranges, and each numerical range may be bound to a different preset coefficient, which is not limited in the embodiment of the present invention.

Abstract

Embodiments of the invention relate to the technical field of communications and disclose an image control method and a user terminal. The method comprises: recording a starting point and an ending point of a continuous track input on a display screen; determining the length of a linear segment for connecting the starting point with the ending point; determining an area ratio of a rectangular region taking the length of the linear segment as the length of two diagonal lines to the display screen; determining a rotational direction of the linear segment rotating to be parallel to an X axis or a Y axis at a minimal rotational angle; and adjusting the size of a display image of the display screen according to the rotational direction and the area ratio. By implementing the embodiments of the invention, when a user inputs the continuous track on the display screen by using one finger, a user terminal can increase or reduce the size of the display image of the display screen, so that the threshold of zooming in and out the display image of the display screen can be reduced and the user experience can be improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for controlling a screen and a user terminal. Background technique [0002] With the continuous development and maturity of communication technology, the increasingly popular smart terminals, especially user terminals, have more and more personalized needs of users. Existing user terminals, especially portable user terminals, have relatively small display screens. For poor eyesight such as myopia, presbyopia, or amblyopia, or when it is necessary to browse and observe text, pictures, and videos on the display screen in detail, the It is not convenient to observe the screen on the display screen. In practical applications, two fingers are usually used to touch the display screen at the same time and perform a reverse sliding operation to realize the enlargement of the display screen. This method requires the user to use two fingers at the same time, which invisibl...
