Embodiment Construction

[0047] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings, which cannot be used to limit the protection scope of the present invention. It should be noted that, in the case of no conflict, the embodiments in the present application and various manners in the embodiments can be combined with each other.

[0048] see figure 1 , the present invention proposes a method for adjusting screen display, comprising:

[0049] Step 100, judging whether the screen is in working state, if so, starting the front camera to capture images.

[0050] In this step, when it is determined that the screen is in a non-working state (such as a dormant state, or a locked screen state, etc.), the step of judging whether the screen is in a working state is continued after a preset time.

[0051] In this step, judging whether the screen is in a working state belongs to the common knowle...

Abstract

The invention discloses a screen display adjusting method and device. The method comprises following steps of judging whether a screen is in a working state or not; if the screen is in the working state, starting a front-mounted camera to capture an image; when it is judged that a face is in the captured image, obtaining the facial feature distance numerical value in the image; and when it is judged that the facial feature distance numerical value is more than or equal to a preset maximum threshold value, reducing the brightness and / or transparency of the screen. Through adoption of the scheme provided by the invention, the brightness and / or transparency of the screen is adjusted according to the facial feature distance numerical value; the screen display is adjusted automatically and timely; the distance between the face and the screen is directly reflected by the facial feature distance numerical value, therefore, the habit of a user is unconsciously influenced by the scheme of the invention; and the eyesight of the user is protected.

Description

technical field [0001] The invention relates to mobile terminal technology, in particular to a method and device for adjusting screen display. Background technique [0002] Mobile terminals (such as smart phones) are becoming more and more popular in our lives, and are loved by many teenagers because of their rich entertainment functions and easy usage. However, even in adults, after a long period of continuous use in incorrect ways, the vision will decline. However, the eyesight of teenagers is still in the immature stage. After long-term continuous use in incorrect ways, vision loss or pseudomyopia has become a growing worry. And teenagers have low self-control ability, if they cannot be guided, they will form a habit of incorrect use for a long time. [0003] In order to prevent vision loss caused by users using mobile terminals for a long time, existing methods generally include: [0004] The front panel of the electronic device is equipped with a front camera and a d...
