Embodiment 1

[0034] figure 1 It is a schematic flowchart of a method for adjusting screen brightness provided by Embodiment 1 of the present invention. The method can be executed by a device for adjusting screen brightness, wherein the device can be implemented by software and / or hardware, and can be built in as a part of a mobile device. in the mobile device. Such as figure 1 As shown, the method includes:

[0035] Step 101, identifying the position of the light intensity sensor disposed on the opposite side of the rotatable camera.

[0036] Wherein, the light intensity sensor can rotate with the rotation of the rotatable camera.

[0037] The mobile device in this embodiment may be a smart phone, a digital camera, or a tablet computer provided with a light intensity sensor. The opposite surfaces refer to two opposite surfaces on which the light intensity sensor and the rotatable camera are respectively arranged on the mobile device. Exemplarily, in an initial state, the rotatable cam...

Embodiment 2

[0049] figure 2 It is a schematic flowchart of a method for adjusting screen brightness provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above embodiments. In this embodiment, the light intensity data obtained by controlling the light intensity sensor on the front of the mobile device , after adjusting the brightness of the display screen according to the light intensity data, a step is added: if it is detected that the rotatable camera is rotated and the working status of the rotatable camera is confirmed to be off, keep the brightness of the display screen unchanged until the light intensity sensor is rotated to The front of the mobile device.

[0050] Correspondingly, the method of this embodiment includes the following steps:

[0051] Step 201, identifying the position of the light intensity sensor disposed on the opposite side of the rotatable camera.

[0052] Step 202 , judging whether the location is located on a non...

Embodiment 3

[0060] image 3 It is a schematic flowchart of a method for adjusting screen brightness provided by Embodiment 3 of the present invention. The method can be executed by a device for adjusting screen brightness, wherein the device can be implemented by software and / or hardware, and can be built in as a part of a mobile device. in the mobile device. Such as figure 1 As shown, the method includes:

[0061] Step 301, identifying the position of the light intensity sensor disposed on the opposite side of the rotatable camera.

[0062] Wherein, the light intensity sensor can rotate with the rotation of the rotatable camera.

[0063] Step 302. Determine whether the location is located on the back of the mobile device, and if yes, execute step 303.

[0064] When the position of the light intensity sensor is located at the back of the mobile device, the rotatable camera should be located at the front of the mobile device. At this time, the light intensity data of the front of the m...

Abstract

The embodiment of the invention relates to the technical field of mobile equipment, in particular to a method and device for adjusting brightness of a screen. The method comprises the steps that the position of a light intensity sensor arranged on the opposite face of a rotatable camera is recognized, and the light intensity sensor can rotate along with rotation of the rotatable camera; if the position is not located on the front face of the mobile equipment, the work state of the rotatable camera can be confirmed; if it is confirmed that the rotatable camera is in the turn-off work state, the rotatable camera is controlled to rotate so that the light intensity sensor can be rotated to the front face of the mobile equipment, and the light intensity sensor is controlled to obtain light intensity data of the front face of the mobile equipment; the brightness of the display screen is adjusted according to the light intensity data. According to the technical scheme, the problems that due to the fact that the light intensity sensor on the mobile equipment with the rotatable camera rotates, the light intensity measuring value is inaccurate, and then errors are generated when the brightness of the display screen is adjusted are effectively solved, and the accuracy of adjusting the brightness of the display screen is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of mobile devices, and in particular to a method and device for adjusting screen brightness. Background technique [0002] With the rapid development of smart mobile device technology, the functions of mobile devices are constantly improving. Many mobile devices are equipped with display screens. In order to enable users to see the content on the display screen clearly under different lighting conditions, and at the same time reduce power consumption, a light intensity sensor is usually installed above the display screen of the mobile device. The light intensity sensor senses changes in the external light intensity to obtain light intensity data, and then automatically adjusts the brightness of the display screen. [0003] Now, the camera function of mobile devices brings convenience to users who like to take pictures, especially mobile devices with rotatable cameras, which are deeply ...
