Embodiment 1

[0023] figure 1 It shows a flow chart of a method for adjusting the brightness of a smart terminal flashlight provided by the first embodiment of the present invention, and the details are as follows:

[0024] Step S11 , detecting whether the touch screen receives a touch screen action.

[0025] In this step, the smart terminal detects whether the touch screen receives a touch screen action, where the touch screen action includes an action of sliding the touch screen. Specifically, after the smart terminal detects that the flashlight of the smart terminal is turned on, it detects whether the touch screen receives a touch screen action, so as to avoid subsequent misjudgment.

[0026] Step S12, when the touch screen receives a touch screen action, determine the sliding direction and the vertical distance of the touch screen action.

[0027] In this step, the sliding direction and the vertical amount of the sliding distance refer to figure 2 . Wherein, the sliding direction ...

Embodiment 2

[0049] image 3 It shows a structural diagram of a brightness adjustment device for a smart terminal flashlight provided by the second embodiment of the present invention. The brightness adjustment device for a smart terminal flashlight can be applied in a smart terminal, and the smart terminal includes a mobile phone, a smart phone, a laptop Computers, digital broadcasting terminals, PDA (personal digital assistants), PMP (portable multimedia players), navigation systems, etc. Embodiments described in this disclosure may be applied to stationary terminals such as digital televisions, desktop computers, etc., except when applied only to mobile terminals. For ease of description, only parts related to the embodiments of the present invention are shown.

[0050] The brightness adjustment device of the smart terminal flashlight includes: a touch screen action detection unit 31 , a sliding distance vertical amount determination unit 32 , a vertical amount ratio determination unit...

Abstract

The invention relates to the field of smart terminals and provides a smart terminal flashlight brightness adjusting method and device. The method comprises the steps of detecting whether a touch screen receives a screen touch movement; when the touch screen receives the screen touch movement, determining the sliding direction of the screen touch movement and the perpendicularity quantity of the sliding distance; determining the ratio of the perpendicularity quantity of the sliding distance to the perpendicularity quantity of the touch screen; adjusting the brightness of a flashlight according to the sliding direction of the screen touch movement and the ratio of the perpendicularity quantity of the sliding distance to the perpendicularity quantity of the touch screen. According to the embodiments of the invention, the brightness better meeting the requirement can be obtained through adjustment.

Description

technical field [0001] Embodiments of the present invention belong to the field of smart terminals, and in particular relate to a method and device for adjusting the brightness of a smart terminal flashlight. Background technique [0002] The flashlight of the smart terminal has the same lighting function as the commonly used lighting fixtures. When the flashlight APP of the smart terminal is turned on, the smart terminal will emit light, but because most of the flashlights of the smart terminal do not have a brightness adjustment function, it brings great inconvenience to the user. [0003] At present, the existing brightness adjustment method for smart terminals is usually to display the brightness selection gear on the flashlight APP interface. When the user selects the brightness of a certain gear, the brightness corresponding to the gear will be emitted. However, due to the limited brightness options displayed on the flashlight APP interface, it is difficult to adjust ...
