Embodiment 1
[0052] This embodiment will be described from the perspective of a device for adjusting screen brightness. Specifically, the device for adjusting screen brightness may be integrated into a mobile terminal, and the mobile terminal may be a device such as a smart phone or a tablet computer.
[0053] A method for adjusting screen brightness, comprising: sensing the ambient light in the current environment of a mobile terminal through a camera to obtain a corresponding electrical signal; judging whether the electrical signal satisfies a preset condition, and if so, then according to the electrical signal The screen brightness of the mobile terminal is adjusted.
[0054] Such as figure 1 As shown, the screen brightness adjustment method, the specific process can be as follows:
[0055] 101. Use the camera to sense the ambient light of the environment where the mobile terminal is currently located, so as to obtain a corresponding electrical signal.
[0056] In the embodiment of th...
Embodiment 2
[0096] According to the method described in Embodiment 1, an example will be given below for further detailed description.
[0097] In this embodiment, it will be described in detail by taking the screen brightness adjusting device integrated in a smart phone as an example to adjust the screen brightness of the mobile terminal.
[0098] Such as figure 2 As shown, a screen brightness adjustment method, the specific process can be as follows:
[0099] 201. The smart phone judges whether it currently satisfies the preset photosensitive condition; if so, execute step 202; otherwise, end.
[0100] Specifically, in order to reduce the power consumption of the smart phone, the light-sensing operation can be performed when the smart phone is in the wake-up state for a long time, that is, the step "judging whether the smart phone currently meets the light-sensing condition" may specifically include:
[0101] The smart phone judges whether it is currently in a wake-up state;
[0102...
Embodiment 3
[0124] In order to better implement the above method, an embodiment of the present invention also provides a screen brightness adjustment device, which can be integrated into a mobile terminal, and the mobile terminal can specifically include mobile phones, tablet computers, notebook computers and other devices. Such as Figure 3a As shown, the screen brightness adjustment device may include: an acquisition module 301, a first judgment module 302 and an adjustment module 303, as follows:
[0125] The acquiring module 301 is configured to sense the ambient light of the environment where the mobile terminal is currently located through the camera, so as to acquire corresponding electrical signals;
[0126] The first judging module 302 is configured to judge whether the electrical signal satisfies a preset condition;
[0127] The adjusting module 303 is configured to adjust the screen brightness of the mobile terminal according to the electrical signal when the first judging mod...
