Referring to fig. 1, fig. 1 is a first flowchart of a screen brightness adjusting method provided in an embodiment of the present application. As shown in fig. 1, a method for adjusting screen brightness includes the following steps:
step 101, when detecting that a human body exists in a target range outside a screen, acquiring the position of the human body relative to the screen and the relative distance between the human body and the screen in the position.
The target range may specifically be a measurement range that can be detected by the detector, or a set effective detection range.
The screen may be a screen disposed on the terminal, and specifically, the screen is disposed around a main body of the terminal, and specifically, the terminal may be a sound box. Correspondingly, the screen is arranged on the sound box and is arranged on the main body of the sound box in a surrounding mode.
Specifically, the screen may be a complete display screen or a display screen formed by a display screen array including a plurality of display screens, and is disposed around the main body of the sound box.
As an optional implementation manner, the detecting that there is a human body in the target range outside the screen includes:
detecting an external object through an infrared induction device, a radar induction device or a picture acquisition device to obtain a detection result; and when the detection result is consistent with the set human body detection data, determining that the human body exists in the target range outside the screen.
That is, the infrared sensing device may perform infrared detection on an external object, and when data of the infrared detection result, such as shape, size, and area, is consistent with set human detection data, it is determined that a human body exists within a detected target range. And the direction of the human body and the relative distance between the human body and the screen in the direction can be further obtained through the infrared detection result.
Or, radar detection can be carried out on an external object through the radar sensing device, and when the radar detection result is consistent with the set human body detection data, the human body in the detected target range is determined. And the direction of the human body and the relative distance between the human body and the screen in the direction can be further obtained through a radar detection result.
Alternatively, the image acquisition device, such as a camera, may be used to perform image acquisition and recognition on the external object, and when the detection result is consistent with the set human body detection data, it is determined that a human body is present within the detected target range. And the orientation of the human body and the relative distance between the human body and the screen in the orientation can be further obtained through the collected pictures.
And 102, determining a corresponding first display area on the screen and a second display area outside the first display area on the screen according to the orientation.

Wherein the second display region may be in a region outside the first display region on the screen; here, the first display region and the second display region may be at least one.
Alternatively, all display regions except the second display region in the screen may be determined as the second display region.
That is, the determining a second display region on the screen other than the first display region includes: and determining all display areas except the second display area in the screen as the second display area.
In a specific application process, the division of the area positions of the first display area and the second display area may be specifically set as required.
Optionally, determining the corresponding first display area on the screen according to the orientation includes:
and step 21, determining a content display column on the screen corresponding to the orientation according to the orientation.
Wherein the content display bar includes: a clock display bar, a music information display bar or a floating window display bar.
Different display columns are displayed on the screen, and different display contents are displayed in the different display columns. In this step, it is necessary to determine a content display field displayed at a position on the screen opposite to the position of the human body.
And step 22, determining a window display area of the content display bar in the screen.
After the corresponding content display bar is determined and obtained based on the position of the human body, a window display area of the content display bar in the screen is obtained, and then the area in the screen is determined. The position, size, etc. of the window display area of the content display bar may be fixed in advance, or may be based on a display area determined after manual adjustment by the user.
And step 23, determining the window display area as a first display area corresponding to the direction.
The content display bar is corresponding to the display area on the screen, so that when the position of a human body is determined, the display area is divided by the display content on the screen, and people in different positions can conveniently check different display contents.
Step 103, determining a first screen display brightness matched with the first display area and determining a second screen display brightness matched with the second display area according to the relative distance.
Specifically, the screen display brightness corresponding to the different display areas may be set according to actual needs, where the first screen display brightness is different from the second screen display brightness.
Specifically, the first screen display brightness is greater than the second screen display brightness. Realize that the human position of being in high-brightness display, other regions then low-brightness display, different display positions carry out distinctive luminance in the realization display screen and show, when the user of being convenient for effectively looks over the display content, reduce energy loss, promote the electric quantity sustainable duration.
And 104, adjusting the brightness of the first display area in the screen to the first screen display brightness, and adjusting the brightness of the second display area to the second screen display brightness.
After the display brightness of different areas in the display screen is determined, brightness adjustment can be performed on the relevant areas, so that the brightness of the screen can be adjusted, and the electricity consumption is saved.
In the practical application process, taking the sound box as an example, when the infrared sensing device arranged on the sound box detects that a human body exists in the reading range of the screen, detecting the distance between the human body and the screen of the sound box and the orientation of the human body relative to the screen by a detection device arranged on the sound box, determining a target content display window corresponding to the orientation, and determining a first area of the screen corresponding to the target content display window and a second area of the screen other than the first area, determining a first screen brightness matched with the first region and a second screen brightness matched with the second region based on the distance, and adjusting the brightness of the first area in the screen of the sound box to the first screen brightness and the brightness of the second area to the second screen brightness, so as to realize different brightness adjustment of different areas on the screen of the sound box.
In the embodiment of the application, confirm the different screen brightness of the correspondence of different regions in the screen according to the user apart from the distance of screen and user for the position of screen, and then adjust the screen of audio amplifier according to the screen brightness in the different regions of confirming, realize that different regions carry out different brightness control on the audio amplifier screen, when the user of being convenient for effectively looks over the display content, reduce energy loss, promote electric quantity duration.
