All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be implemented in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The method, the apparatus, the electronic device and the readable storage medium for controlling the screen refresh rate according to the embodiments of the present application are described in detail below with reference to the accompanying drawings.
The inventor finds that factors such as the amount of light entering and the light emission of the screen can affect the imaging quality of the camera under the screen. However, the amount of light entering is affected by the transparency of the screen itself and screen refresh. Especially, when the under-screen camera starts to expose, and the screen refreshes the frame rate, the color and brightness of the screen around the under-screen camera will change, and further the imaging quality of photographing will be affected. The higher the refresh rate of the screen is, the stronger the interference to the light entering of the camera under the screen is, the greater the influence on the imaging quality of the camera under the screen is, and the more serious the image distortion is.
In order to solve the foregoing problem, embodiments of the present application provide a method and an apparatus for controlling a screen refresh rate, an electronic device, and a readable storage medium, which are capable of improving imaging quality of an off-screen camera.
Fig. 1 is a schematic flowchart of a method for controlling a screen refresh rate according to an embodiment of the present application.
As shown in fig. 1, the method for controlling the screen refresh rate includes:
s110, under the condition that the shooting preview image is displayed on the screen, the exposure state of the camera under the screen is detected.
And S120, reducing the screen refresh rate of the first screen area and keeping the screen refresh rate of the second screen area unchanged under the condition that the exposure state of the camera under the screen meets the preset condition.
The first screen area is a screen area corresponding to the camera under the screen, and the first screen area is different from the second screen area.
Specific implementations of the above steps will be described in detail below.
In the embodiment of the application, the exposure state of the camera under the screen is detected under the condition that the shooting preview image is displayed in the screen, and under the condition that the exposure state of the camera under the screen meets the preset condition, the interference of screen refreshing on the light entering of the camera assembly under the screen is reduced by reducing the screen refreshing rate of the first screen area corresponding to the camera under the screen, and as the screen refreshing rate of the second screen area is kept unchanged, the imaging effect of the shooting preview image cannot be influenced in the process of exposing and imaging the shooting preview image, so that the imaging quality of the camera under the screen can be improved.
The following describes in detail a specific implementation of S120 in conjunction with the accompanying drawings.
In some embodiments of the present application, as shown in fig. 2, fig. 2 is a schematic diagram of a display screen provided in one embodiment of the present application. The first screen area 21 includes a screen area corresponding to the off-screen camera component 20, and the second screen area 22 is an area of the display screen other than the first screen area 21.
In some embodiments of the present application, when it is detected that the terminal starts to view through the camera but the camera under the screen is not exposed yet, or the camera is already in the exposure process, it is determined that the exposure state of the camera under the screen meets the preset condition. At this time, S120 further includes the following steps:
under the condition that the exposure state of the under-screen camera meets a preset condition, acquiring a first moment when the under-screen camera starts to be exposed;
from the first time, the screen refresh rate in the first screen region is reduced.
Alternatively, in a case that it is detected that the terminal starts to view through the camera, but the off-screen camera is not yet exposed, the first time point for acquiring the exposure start of the off-screen camera may be: acquiring the corresponding moment when a user presses a shooting key; in the case that the camera is already in the exposure process, the first time for acquiring the exposure start of the off-screen camera may be: and detecting the corresponding moment when the camera is exposed.
As an example, when the user starts the photographing mode of the electronic device and presses the photographing key, it is recorded as a first time T1, and at this time, the control device of the screen refresh rate starts to decrease the screen refresh rate of the screen pixel units in the first screen region and keeps the screen refresh rate of the screen pixel units in the second screen region unchanged.
In the embodiment of the application, in the process of exposing the shot original image data, the screen pixel unit in the first screen area of the under-screen camera component is controlled to stop refreshing, so that the interference of screen refreshing on the light entering of the under-screen camera component is reduced, and the screen pixel unit in the second screen area is kept to be refreshed continuously, so that in the process of exposing the original image data, the control effect of the screen refreshing rate of the whole target image cannot be influenced, the additional hardware cost is not required to be increased, and the imaging quality of the under-screen camera can be improved.
In order to improve the display effect of the display screen when the off-screen camera is not exposed, in some embodiments of the present application, after S120, the method further includes the following steps:
and restoring the screen refresh rate in the first screen area under the condition that the exposure of the camera under the screen is finished.
In some embodiments of the present application, a time when the off-screen camera starts to expose is referred to as a first time T1, and a time when the off-screen camera ends to expose is referred to as a time T2, during a period from T1 to T2, the screen refresh rate of the first screen region may be kept low, and the screen refresh rate of the first screen region may be recovered after the off-screen camera ends to expose (i.e., after the time T2) is detected.
In some embodiments, the screen refresh rate of the first screen region may be restored to be consistent with the screen refresh rate before the reduction, or the screen refresh rate of the first screen region may be restored to be consistent with the second screen region.
Illustratively, the screen refresh rate of the first screen region is 90hz before the first time, the screen refresh rate of the first screen region is reduced to 30hz during the period from T1 to T2, and the screen refresh rate of the first screen region is restored to 90hz after the exposure of the off-screen camera is finished, i.e., after the time T2. In addition, if the screen is a screen whose refresh rate can be dynamically adjusted, the screen refresh rate of the first screen region may be adjusted to match the screen refresh rate of the second screen region after time T2.
In the embodiment of the application, after the control device of the screen refresh rate detects that the exposure of the camera under the screen is finished, the screen refresh rate in the first screen area can be recovered, so that the display screen is more flow and clearer when displaying the content.
In order to better reduce the influence of the screen refresh rate on the light-entering amount of the under-screen camera and better improve the imaging quality of the under-screen camera, the determination of the area range of the first screen area for reducing the screen refresh rate is particularly important in the exposure process.
As such, in some embodiments of the present application, the area range of the first screen area may also be determined based on the display information and/or the environment information of the captured preview image, specifically, refer to the flowchart shown in fig. 3.
Fig. 3 is a flowchart illustrating a method for controlling a screen refresh rate according to another embodiment of the present application. The control method of the screen refresh rate specifically comprises the following steps:
s310, determining the area range of the first screen area.
Wherein the area range in the first screen area is determined according to at least one of: parameter information of the under-screen camera shooting assembly, display information of the shot preview image and environment information; wherein the display information comprises at least one of: luminance information and chrominance information.
Wherein, the parameter information can be parameters such as focal length of the camera; the environment information may be day, night, indoor and outdoor scene information, etc.
With respect to a specific determination manner of the area range of the first screen area in S310, a detailed description will be made hereinafter.
And S320, detecting the exposure state of the camera under the screen under the condition that the shooting preview image is displayed on the screen.
S330, reducing the screen refresh rate in the first screen area and keeping the screen refresh rate in the second screen area unchanged under the condition that the exposure state of the camera under the screen meets the preset condition.
The first screen area is a screen area corresponding to the camera under the screen, and the first screen area is different from the second screen area.
S320 and S330 are the same as S110 and S120 shown in fig. 1, and are not described herein again.
In the embodiment of the application, when the area range of the first screen area is determined, that is, the fixed area range may be determined by parameter information of the off-screen camera component, and the area range may be dynamically determined according to display information and/or environment information of the shot preview image, so that the area range may be dynamically adjusted in the process of exposing different shot images. And then under the condition that the exposure state of the camera satisfies the preset condition under the screen, through reducing the screen refresh rate in the first screen region that the camera corresponds under the screen, and then reduce the screen refresh and to the subassembly of making a video recording under the screen interference of advancing light, and because keep the screen refresh rate in the second screen region unchangeable, so in the in-process of exposing to light and formation of image to shooting preview image, still can not influence the formation of image effect of shooting preview image, thereby can improve the formation of image quality of camera under the screen.
The specific implementation manner of determining the area range of the first screen area in S310 is described in detail below by some embodiments.
When the area range of the first screen area is determined according to the parameter information of the off-screen camera component, the area range may be determined according to the focal length in the parameter information. Different focal lengths may correspond to different zone ranges, for example, a zone range corresponding to a short focal length may be smaller than a zone range corresponding to a long focal length.
In the embodiment of the application, the fixed area range is determined through the parameter information of the under-screen camera shooting component, so that the area range of the first screen area is more suitable for the parameters of the under-screen camera shooting component, and the imaging quality of the under-screen camera is better.
When the area range of the first screen area is determined according to the display information of the photographed preview image, the target brightness corresponding to the display information may be determined. Next, after determining the target brightness, the area range of the first screen area may be calculated by expression (1) based on the target brightness and the range threshold of the first screen area.
Wherein the range threshold may be a maximum area range value allowed for the first screen area.
For example, if the target brightness corresponding to the environment information is low, the area range of the first screen area is small; if the target brightness corresponding to the environment information is high, the area range of the first screen area is also large.
When the area range of the first screen area is determined according to the chromaticity in the display information, the area range of the first screen area may be determined based on the chromaticity information in the captured preview image. For example, the chromaticity information of the captured preview image may be weighted to obtain the target chromaticity, and then the area range corresponding to the target chromaticity may be used as the area range of the first screen area.
In some embodiments, the environment information may be day, night, indoor or outdoor, and different environments may correspond to different area ranges of the first screen area.
When the area range of the first screen area is determined according to the environment information, for example, if the environment information is in the daytime at the moment, the area range a corresponding to the daytime can be determined according to the preset corresponding relationship between the environment information and the area range, and the area range of the first screen area is determined to be a; if the environmental information is at night, determining an area range B corresponding to the night according to a preset corresponding relationship between the environmental information and the area range, and determining the area range of the first screen area as B. The area range of the first screen area corresponding to the environment information in daytime may be larger than the area range of the first screen area corresponding to night.
In the embodiment of the application, the dynamic determination of the area range is realized according to the environment information and/or the display information of the original image data, so that the area range can be dynamically adjusted in the process of exposing different shot images, and the imaging quality of the camera under the screen is better.
