Referring to FIG. 1 , the figure shows the implementation flow of the ambient light detection method in the embodiment of the present application. For the convenience of description, only the parts related to the content of the present application are shown in the figure.

The display screen described in the embodiment of the present application is a liquid crystal display (Liquid Crystal Display, LCD) with a backlight module, and may also be a self-illuminating organic light-emitting diode display (Organic Light-Emitting Diode, OLED). The ambient light sensor can perceive the light intensity of surrounding light, and is mainly composed of photosensitive elements, such as photoresistors, photodiodes, phototransistors, silicon photocells, etc., and according to the detected light intensity of ambient light, inform The electronic device automatically adjusts the brightness of the backlight of the display screen, so that the brightness of the backlight of the display screen matches the light intensity of the ambient light, thereby improving the user's viewing effect on the display screen.

In some embodiments, the ambient light detection method includes the following steps:

101. Receive an ambient light detection instruction.

Wherein, the ambient light detection instruction is used to instruct the ambient light sensor to detect the light intensity of the ambient light.

In some embodiments, the electronic device may preset some conditions for triggering the generation of the ambient light detection instruction, and when certain conditions are met, the ambient light detection instruction may be generated. For example, the preset duration of each interval, or when the display screen switches from the off-screen state to the on-screen state, triggers the acquisition of ambient light, and the specific conditions can be set according to the actual situation.

For example, if the electronic device is set to trigger an action of acquiring ambient light every 5 seconds, then an ambient light detection instruction is generated every 5 seconds, and the electronic device executes corresponding actions after receiving the ambient light detection instruction.

In some embodiments, receiving the ambient light detection instruction can be received by monitoring whether there is an ambient light detection instruction in the system, or it can be actively trying to obtain the ambient light detection instruction at a preset position, which is not made in this application. limited.

102. According to the ambient light detection instruction, determine whether the display screen is in a working state; if yes, display a full black frame image on the display screen; if not, do not respond.

Wherein, the working state generally refers to that the display screen is in a “bright screen” state, that is, a state of working and displaying content.

Because adjusting the intensity of the display's backlight only makes sense when the display is in use. Therefore, after the electronic device receives the ambient light detection instruction, it needs to determine whether the display screen is in a working state.

In some embodiments, to determine whether the display screen is in a working state, parameters related to the working state of the display screen may be detected.

For example, when the value of "parameter A" reflects the state of the display screen, the state of the display screen includes "working state" or "off state". If when the "parameter A" is "1", the display is in the "working state", and when the "parameter A" is "0", the display is in the "off state", then when the "parameter A" is detected When the value of " is "1", it can be determined that the display screen is working.

In some embodiments, determining whether the display screen is in a working state may also be determined by detecting the current voltage value of the display screen.

For example, when the current voltage value of the display screen is within the preset working voltage range, it can be determined that the display screen is in a working state. Otherwise, when the voltage of the display screen is not within the preset operating voltage range, it can be determined that the display screen is in an off state or other standby states.

It should be noted that there are other ways to determine whether the display screen is in a working state, all of which can be realized by other existing technologies, which are not limited in this application.

103. Displaying an all-black frame image on the display screen, where the all-black frame image carries a preset mark.

Wherein, a frame is a single frame that is the smallest unit in an image or animation, or a single frame that is displayed every time the display screen is refreshed. The all-black frame image refers to an image of a single frame in which all pixels in the display screen are displayed as black. The preset mark is used to trigger an operation corresponding to the mark when the mark is detected, for example, to control the ambient light sensor to work.

In some embodiments, displaying an all-black frame image on the display screen may be that one or more frames of images displayed on the display screen are all-black frame images.

For example, during the display process of the display screen, the display screen can refresh and display 60 frames of images within 1 second, then displaying a full black frame image on the display screen can be a full screen display of a black image in one of the frames, or a certain number of frames. Displays a black image full screen in the frame.

In some embodiments, the preset mark can be marked by adding a special value in a specific position of the display information of the full black frame image; or adding a certain instruction to the display information of the full black frame image to When the electronic device reads the display information, it can read the instruction by the way, and execute the operation corresponding to the instruction.

It should be noted that the above-mentioned marking method is only used for reference, and the marking method can also adopt other methods in the prior art, and the embodiment of the present application does not limit the specific marking means.

104. When the preset mark is detected, control the ambient light sensor to detect the light intensity of the ambient light.

In some embodiments, when the preset flag is detected, a corresponding ambient light detection instruction will be executed to trigger the work of the ambient light sensor. When the ambient light sensor is working, the ambient light sensor can convert the photosensitive data of the current ambient light (such as the change of the detection amount caused by the change of the resistance value of the photosensitive component) into light intensity data, and send the light intensity data to the electronic device Processing in the processor to complete the detection and control of ambient light.

At this time, because the display screen displays a completely black frame image, it can be considered that the influence of the backlight on the display screen on the ambient light sensor is minimized at this time, thereby improving the detection accuracy of the ambient light sensor.

In some embodiments, because the ambient light sensor takes a certain amount of time to perform the ambient light acquisition action, in order to ensure that the display of a full black frame image can minimize the impact on the ambient light sensor, the display duration of the full black frame image can be longer than the ambient light The detection time required for the sensor to detect ambient light.

For example, if the time required for the ambient light sensor to detect ambient light is 5ms, the display time of the all-black frame image should be greater than 5ms, so as to ensure that the ambient light sensor will not be disturbed by the sudden jump of the all-black frame image in the process of detecting ambient light. Its detection accuracy is affected.

In some embodiments, the ambient light sensor may be disposed in a non-display area other than one side of the display screen, or may be disposed behind the display screen, that is, on the other side relative to the display direction. When the ambient light sensor is arranged behind the display screen, the ambient light sensor will be more affected by the backlight of the display screen due to the blocking of the display screen. Displaying a full black frame image when the ambient light sensor detects ambient light can more effectively reduce the influence of the display backlight, and greatly improve the detection accuracy and reliability of the ambient light sensor.

In the ambient light detection method provided in the embodiment of the present application, when the ambient light sensor needs to obtain ambient light, if the display screen is in the working state at this time, a full black frame image is displayed on the display screen, and when a full black frame is detected After the image is pre-set and marked, the light intensity of the ambient light is controlled to detect, which can reduce the impact of the backlight of the display screen on the ambient light sensor, thereby improving the detection accuracy of the ambient light sensor to the ambient light.

Referring to FIG. 2 , the figure shows the implementation process of displaying a full black frame image provided by the embodiment of the present application. For the convenience of description, only the parts related to the content of the present application are shown in the figure.

In some embodiments, displaying a full black frame image on the display screen includes:

201. Acquire display information of the all-black frame image.

Wherein, the display information includes the position of each pixel in a certain frame of image, and the color or gray scale to be displayed by the pixel, through which a certain frame of image corresponding to it can be displayed on the display screen. The display information of the all-black frame image may be pre-stored in the memory of the electronic device.

202. Use the display information of the all-black frame image as the display information of the next frame image, and mark the display information of the all-black frame image.

Wherein, the next frame image is relative to the currently displayed frame image, for example, the frame number position of the currently displayed frame image is "N", then the frame number position of the next frame image is the next frame of the currently displayed frame image , that is, "N+1".

In some embodiments, the following steps may be included:

Obtain the display timing information of the display content, and determine the next frame of image according to the display timing information;

Obtain the display information of the next frame image, and replace the display information of the next frame image with the display information of the full black frame image.

Among them, the display timing information is used to mark the display sequence of each frame in the display process of the display content, and each frame image to be displayed will have a corresponding frame number position, and the display timing information can reflect the frame number position of each frame image .

For example, if a segment of video needs to be played, the display information of each frame in the segment of video is generally stored in the memory, and the storage location of the display information of each frame of image is marked.

When it is necessary to obtain the display information of the next frame of image, the frame number position of the currently displayed frame image can be determined through the display timing information of the segment of the image, and according to the frame number position in the storage position of the display information of the next frame image Information is obtained.

For example, if the frame number position of the currently displayed frame image is "N", then it can be determined that the frame number position of the next frame image is "N+1", and then according to the frame number position "N+1" of the next frame image Information will be displayed in the corresponding storage location for acquisition.

When the display information of the next frame image is obtained, the display information of the next frame image stored therein can be replaced with the display information of the full black frame image, and the display information of the full black frame image is stored in the next frame image In the storage location of the displayed information.

In some embodiments, the mark can be marked by adding a special value in a specific position of the display information of the all-black frame image; or adding a certain instruction to the display information of the all-black frame image to When the electronic device reads the display information, it can read the instruction by the way, and execute the operation corresponding to the instruction.

It should be noted that the above-mentioned marking method is only used for reference, and the marking method can also adopt other methods in the prior art, and the embodiment of the present application does not limit the specific marking means.

203. When loading the next frame of image, display the full black frame image on the display screen according to the display information of the full black frame image.

In some embodiments, if the display sequence of the currently displayed frame of image ends, in order to display the next frame of image, the display information of the next frame of image will be loaded at this time.

Because the display information of the next frame image has been replaced with the display information of the all-black frame image, when the next frame image is loaded, the display information of the all-black frame image is actually loaded. At this time, when the next frame image is displayed, then A full black frame image will be displayed.

It can be seen from this that by acquiring the display information of the full black frame image and replacing the display information of the next frame image to be displayed with the display information of the full black frame image, the full black frame image is loaded when the next frame image is loaded. display, it is possible to insert a full black frame image into any original display content, making it easier to insert a full black frame image.

Referring to FIG. 3 , the figure shows the implementation process of controlling the ambient light sensor to detect ambient light provided by the embodiment of the present application. For the convenience of description, only the parts related to the content of the present application are shown in the figure.

In some embodiments, when the preset mark is detected, controlling the ambient light sensor to detect the light intensity of the ambient light may include the following steps:

301. Read the display information of the next frame of image;

In some embodiments, in the process of playing an image, when it is necessary to read the display information of the next frame image, the frame number position of the currently displayed frame image can be determined through the display timing information of this segment of image first, and according to the Read the information at the storage position of the display information of the next frame image at the digital position.

For example, if the frame number position of the currently displayed frame image is "N", then it can be determined that the frame number position of the next frame image is "N+1", and then according to the frame number position "N+1" of the next frame image The information displayed in the corresponding storage location can be read.

302. Determine whether the display information of the next frame of image contains a preset mark;

In some embodiments, the preset mark may be acquired and judged by acquiring and judging the parameter corresponding to the preset mark in a specific position of the display information of the next frame of image.

Alternatively, the display information of the next frame of image is executed, and when the display information has an instruction corresponding to the preset mark, it is determined that the display information of the next frame of image contains the preset mark.

If the parameter corresponding to the preset mark is not obtained from the specific position of the display information of the next frame of image, or the display information of the next frame of image does not contain the instruction corresponding to the preset mark, then the next frame can be determined. The display information of the frame image does not include the preset mark.

303. If yes, control the ambient light sensor to detect the light intensity of the ambient light.

In some embodiments, when the display information of the next frame image contains a preset mark, it can be confirmed that the next frame image is a completely black frame image, and at this time, the ambient light sensor can be controlled to detect the light intensity of the ambient light, The opportunity of displaying a completely black frame image is used to make the light intensity of the ambient light acquired by the ambient light sensor close to the actual value of the environment, thereby improving the detection accuracy of the ambient light sensor.

It can be seen from this that by judging whether the display information of the next frame image contains a preset mark, it can be accurately determined whether the next frame image is a full black frame image, and by controlling the environment during the display of the full black frame image The light sensor acquires ambient light. Moreover, this embodiment can quickly identify and determine whether the next frame will display a completely black frame image, so that the ambient light sensor can be activated in advance to improve the system response speed.
