Embodiment Construction

[0059] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0060] In related technologies, smart terminals have the function of automatically adjusting the backlight, but if the smart terminal is in a dark environment, such as in a carry-on bag, if the screen is automatically lit, when the user takes out the smart terminal from the carry-on bag, it will take a long time. The intensity of the backlight of the screen is still adapted to the inte...

Abstract

The invention relates to a brightness adjusting method and a brightness adjusting device. The method comprises the following steps: when a screen is automatically lighted, setting a preset cycle as afirst cycle; acquiring multiple pieces of continuously acquired light intensity information within the preset cycle; determining the brightness of the current backlight according to the multiple pieces of light intensity information; acquiring a time interval from the screen lighting time to the current time; and when the time interval is more than or equal to preset duration, increasing the length of the preset cycle to a second cycle. According to technical scheme, the less the light intensity information acquired in a short cycle is, the more the calculated brightness of the current backlight accords with the brightness of the current environment. Therefore, the current backlight can respond rapidly according to the brightness of the current environment, so that the problem that the brightness adjustment of the backlight is delayed when the environment light is extremely changed is solved and user experience is improved.

Description

technical field [0001] The present disclosure relates to the field of electronics, and in particular, to a brightness adjustment method and device. Background technique [0002] At present, smart terminals are more and more widely used. Most smart terminals interact with users through screens. In order to improve the user experience of user interaction, the backlight of the screen can change the brightness according to the ambient light. For example, from indoors to outdoors at noon on a sunny day, the backlight intensity will be smoothly dimmed so that users can see the content displayed on the screen clearly; feel dazzling. However, if the ambient light changes extremely, the smooth adjustment effect of the backlight adjustment will not be effective, and the user may not be able to see the content displayed on the screen clearly. Contents of the invention [0003] Embodiments of the present disclosure provide brightness adjustment methods and devices. Described techni...
