It should be noted that, in the image capturing method provided by the embodiment of the present invention, the execution subject may be an electronic device, or, a central processing unit (Central Processing Unit, CPU) of the electronic device, or a central processing unit (Central Processing Unit, CPU) of the electronic device for executing image capturing. The method's control module. In the embodiment of the present invention, an image capturing method performed by an electronic device is used as an example to describe the image capturing method provided by the embodiment of the present invention.

The electronic device in the embodiment of the present invention may be an electronic device with an operating system. The operating system may be an Android (Android) operating system, an ios operating system, or other possible operating systems, which are not specifically limited in the embodiment of the present invention.

The following takes the Android operating system as an example to introduce a software environment to which the image capturing method provided by the embodiment of the present invention is applied.

As shown in FIG. 1 , it is a schematic structural diagram of a possible Android operating system provided by an embodiment of the present invention. In FIG. 1, the architecture of the Android operating system includes four layers, namely: an application layer, an application framework layer, a system runtime layer, and a kernel layer (specifically, a Linux kernel layer).

The application layer includes various applications (including system applications and third-party applications) in the Android operating system.

The application framework layer is the framework of the application, and developers can develop some applications based on the application framework layer under the condition of complying with the development principles of the framework of the application. For example, applications such as the system settings app, the system chat app, and the system camera app. Apps such as third-party settings apps, third-party camera apps, and third-party chat apps.

The system runtime layer includes libraries (also called system libraries) and the Android operating system runtime environment. The library mainly provides various resources required by the Android operating system. The Android operating system operating environment is used to provide a software environment for the Android operating system.

The kernel layer is the operating system layer of the Android operating system and belongs to the bottom layer of the Android operating system software layer. The kernel layer provides core system services and hardware-related drivers for the Android operating system based on the Linux kernel.

Taking the Android operating system as an example, in this embodiment of the present invention, a developer may develop a software program for implementing the image capturing method provided by the embodiment of the present invention based on the system architecture of the Android operating system as shown in FIG. The shooting method can be run based on the Android operating system as shown in FIG. 1 . That is, the processor or the electronic device can implement the image capturing method provided by the embodiment of the present invention by running the software program in the Android operating system.

The image capturing method provided by the embodiment of the present invention will be described in detail below with reference to the flowchart of the image capturing method shown in FIG. 2 . Wherein, although the logical sequence of the image capturing method provided by the embodiment of the present invention is shown in the flowchart of the image capturing method, in some cases, the steps shown or described may be performed in a sequence different from that here. For example, the image capturing method shown in FIG. 2 may include S201 and S202:

S201, the electronic device controls the surface light source to be in an on state.

Wherein, that the surface light source is in an on state means that the surface light source emits light, and conversely, that the surface light source is in an off state means that the surface light source stops emitting light.

Optionally, the sequence of executing S201 by the electronic device and turning on the target camera may be any sequence. For example, the electronic device first turns on the target camera and then executes S201.

S202, the electronic device captures an image through a target camera corresponding to the surface light source.

Wherein, the surface light source corresponding to the target camera is used to fill light for the shooting object of the target camera.

It should be noted that, in this embodiment of the present invention, the electronic device may include one or more cameras and one or more surface light sources, and one surface light source corresponds to one camera. Wherein, each surface light source is used to fill light for the shooting object of the corresponding camera, that is, fill light for the shooting object in the framing range of the corresponding camera. That is to say, each surface light source can be used as a supplementary light board for shooting.

Exemplarily, when the photographed object is a person, the image photographed by the electronic device is a person image including a portrait. At this time, the surface light source is used to fill in the light for the photographed person (such as the person's face).

It is understandable that when the user has high requirements for the whitening effect of portrait shooting, in a dark light environment with backlight, weak background light, or high contrast between light and dark, if the person photographed is not filled with light or the effect of fill light is not good, As a result, the portraits in the photographed portraits will be blurred or dim, that is, the quality of the photographed images will be poor.

It should be noted that the light source is an object that can emit light by itself and is emitting light, for example, the sun, an electric light that is turned on, a burning candle, and a lit screen are all light sources.

Optionally, according to the lighting mode, the light source can be divided into a point light source and a surface light source.

The point light source is a concentrated point-like light source. For example, the point light source may be a light emitting diode (Light Emitting Diode, LED) point light source, a common lamp light source, and the like. Specifically, when the point light source emits light to illuminate the object, the angle difference between the light beam and different parts of the object (such as different parts of the person being photographed) is relatively large, or the angle difference between the light beam and different objects is relatively large.

In the related art, a front soft light is set on the electronic device to solve the problem of poor image quality caused by factors such as insufficient light in a dark environment. However, since the front soft light is a point light source, the radiation of the light source is not comprehensive (that is, the light source has a small luminous range), resulting in poor lighting effect on the photographed object, which in turn leads to the quality of the photographed image. still poor. In addition, when the front soft light is used as the light source, the color and brightness of the light source are usually fixed.

It should be emphasized that, compared with point light sources, surface light sources have the characteristics of large luminous range, soft light output, no eye damage, power saving, and natural light. Specifically, the surface light source is a light source that can emit light in a wide range as a whole. For example, the surface light source may be a flat light source, such as a lighted screen or the like. Specifically, when the surface light source emits light to irradiate an object, the light irradiated to different parts of the object (eg, different parts of a person being photographed) can be considered to be parallel. Generally speaking, the distance between the surface light source and the irradiated object is relatively far, and the different light rays received by the irradiated object can be parallel lines.

In the embodiment of the present invention, the surface light source corresponding to the target camera in the electronic device is specifically used to fill light for the object photographed by the target camera in an environment with backlight, weak background light, or a large contrast between light and dark (or a dark environment). Specifically, the electronic device uses a surface light source to illuminate the photographed object, so that a large area of the photographed object can be exposed to the irradiated light, so as to realize the supplementary light for the photographed object.

It can be understood that the luminous range of the surface light source provided by the electronic device is generally larger than that of the point light source, but not too large. In this way, the surface light source is mainly used for illuminating the shooting object, and will not illuminate the shooting background other than the shooting object in the entire framing range of the target camera.

It should be noted that images usually include foreground and background. The foreground of the image may be a picture of a photographed object (such as a person), and the background of the image may be a picture of a photographed background other than the picture of the photographed object in the image.

Generally speaking, when an electronic device captures an image in a dark environment, the user usually requires a better foreground image quality of the subject in the image, such as higher brightness, higher definition, and softer image in the foreground image. The quality of the background pictures other than the foreground picture in the image is not too high. In this way, as long as the effect of filling light for the photographed object is good, such as a large range of fill light output, natural fill light and soft fill light, etc., the electronic device can shoot better images, such as people with clear portraits. image.

In addition, the viewing ranges of different cameras in the electronic device are the same or different.

Wherein, different types of cameras may be included in the electronic device. For example, according to the installation position of the camera in the electronic device, the camera can be divided into a front camera and a rear camera. According to the function of the camera, the camera can be divided into conventional camera, fisheye camera, telephoto camera and wide-angle camera. According to the installation method of the camera, the camera can be divided into pop-up camera, rotatable camera and fixed camera.

It should be noted that the location of the pop-up camera in the electronic device is different, and the viewing range of the camera is different. For example, the viewing range when the pop-up camera is located inside the electronic device is different from that when it is located outside the electronic device. The rotation angle of the rotatable camera is different, and the viewing range of the camera is different. The viewing range of a fixed camera is generally fixed.

Optionally, when the framing range of the target camera changes, the irradiation direction of the surface light source corresponding to the target camera can be changed accordingly, so that the surface light source can continue to fill light for the shooting object in the framing range of the target camera.

In the embodiment of the present invention, the surface light source corresponding to the target camera is realized by the first screen in the electronic device, or realized by the casing in the electronic device; the first screen and the second screen in the electronic device for displaying the shooting preview image are realized. The screen is different.

Optionally, in this embodiment of the present invention, the electronic device may be a folding-screen electronic device. Specifically, the folding screen in the electronic device can be folded, for example, the angle between two screens (or two parts of one screen) folded in the folding screen can be an angle between 0 degrees and 360 degrees. It can be understood that the angle value between the two screens refers to the angle value between the surface on which the display interface of one screen is located and the surface on which the display interface of the other screen is located.

In the following embodiments, the first screen and the second screen in the electronic device are foldable screens as an example for description.

In addition, the number of screens that may be included in the electronic device may be one or more. Specifically, the first screen and the second screen may be implemented by one flexible screen, or implemented by two rigid screens.

It should be noted that, in the image capturing method provided by the embodiment of the present invention, the surface light source can be controlled to be in an on state, and images are captured by the target camera corresponding to the surface light source, so as to realize the supplementary light for the shooting object of the target camera through the surface light source . Among them, since the light source that fills the light for the subject is the light-emitting mode of the surface light source, and the surface light source has the characteristics of a large luminous range, soft light output, no eye damage, power saving, and natural light, etc., it can improve the fill light of the shooting object. The light effect makes the picture quality of the subject in the captured image better. Furthermore, since the light of the surface light source usually does not illuminate the shooting background other than the shooting object in the framing range of the target camera, it will not affect the shooting background picture in the shot image, which can avoid the overall brightening of the image and the resulting image. The problem of increased noise improves the overall quality of images captured by electronic devices. In addition, since the surface light source in the electronic device can be realized by the first screen or the casing, and the first screen is different from the second screen used for displaying the shot preview image. In this way, when the subject is close to the first screen, the electronic device can fill the light for the subject through the first screen; when the subject is close to the housing of the electronic device, the electronic device can fill the light for the subject through the housing, so that the It can improve the flexibility and accuracy of fill light without affecting the display of the shooting preview image.

In a possible implementation manner, the image capturing method provided by the embodiment of the present invention may further include S203 before the above-mentioned S202:

S203, the electronic device controls the light source parameters of the surface light source as target parameters.

Optionally, when the user triggers the electronic device to turn on the target camera, the electronic device may start to control the light source parameter of the target camera as the target parameter. Alternatively, after the user performs a specific trigger input to the electronic device, the electronic device can control the light source parameter of the surface light source as the target parameter.

The target parameters are adjusted by the electronic device according to the ambient light, or user-defined.

In Example 1, the target parameter is adjusted by the electronic device according to ambient light. Among them, the electronic device can detect the parameters of the ambient light, and adjust the light source parameters of the surface light source corresponding to the target camera as the target parameters by comparing the parameters of the ambient light with the preset parameters, so that the parameters of the ambient light are similar to the preset parameters or equal.

It should be noted that the parameters of the ambient light are preset parameters, indicating that the ambient light at the location of the shooting object in the framing range of the target camera is better. At this time, the image quality of the photographed object in the image photographed by the electronic device is better, such as higher brightness and higher definition.

Optionally, in Example 2, the target parameter is user-defined. At this time, when the surface light source corresponding to the target camera works with the target parameters, the supplementary light effect of the shooting object in the framing range of the target camera is the effect required by the user, so that the image of the shooting object in the image captured by the electronic device is A screen that meets user needs.

It should be noted that, in the image capturing method provided by the embodiment of the present invention, the light source parameter of the surface light source corresponding to the target camera can be adjusted as the target parameter, so that the fill light effect of the surface light source on the shooting object of the target camera is the effect required by the user. , so that the effect of the picture of the object in the captured image is the effect required by the user. In addition, since the target parameters can not only be adjusted according to the ambient light, but also can be customized by the user, so the user can flexibly choose any one of the two methods to control the electronic device to adjust the light source parameters of the surface light source corresponding to the target camera. , thereby improving the flexibility of passing the fill light.

In a possible implementation manner, the light source parameters include at least one of the following: light source brightness, light source color, light source shape, and light source angle. The light source angle is the angle between the first surface and the second surface, the first surface is the surface of the electronic device that includes the surface light source corresponding to the target camera, and the second surface is the surface of the electronic device that includes the target camera.

Exemplarily, the value of the brightness of the light source can be normalized to a value between 0 and 100, so as to support the electronic device to adjust the brightness of the light source. The light source color can be any one of the three primary color templates. The shape of the light source can be rectangle, triangle, bar or star, etc. Of course, the shape of the light source includes, but is not limited to, the shapes listed above.

In addition, the different surfaces in the electronic device on the first surface and the second surface, that is, the surface light source corresponding to the target camera and the target camera are located on different surfaces in the electronic device.

It can be understood that, as the angle of the light source changes, the illumination angle of the surface light source corresponding to the target camera to the target photographing object changes.

Exemplarily, in Example 1, the electronic device can detect the color temperature of the ambient light, and realize the color temperature balance in the environment by adjusting the light source parameters of the surface light source corresponding to the target camera. For example, when the electronic device detects that the ambient light is yellowish, the electronic device can adjust the color of the light source of the surface light source so that the ambient light at the location where the object of the target camera is located tends to be white. Alternatively, the electronic device can detect the brightness of the ambient light, and realize the brightness balance in the environment by adjusting the light source parameters of the surface light source. For example, when the electronic device detects that the ambient light is too dark, the electronic device can increase the brightness of the light source of the surface light source, so that the ambient light at the location where the object of the target camera is located becomes brighter.

Optionally, in this embodiment of the present invention, one or more setting options may be provided in the electronic device to support the user to trigger the electronic device to adjust the light source parameters of the surface light source corresponding to the target camera to the target parameters.

Exemplarily, the electronic device may provide an "Auto Mode" option, an "Adjust Brightness" option, an "Adjust Color" option, and an "Adjust Light Source Shape" option. Among them, the "Auto Mode" option is used to trigger the electronic device to adjust the surface light source parameters corresponding to the target camera according to the ambient light. The "Adjust Brightness" option is used to trigger the electronic device to adjust the light source brightness of the surface light source. The "Adjust Color" option is used to trigger the electronic device to adjust the light source color of the surface light source. The "Adjust light source shape" option is used to trigger the electronic device to adjust the light source shape of the area light source.

In addition, the electronic device may also provide an "angle adjustment" option for triggering the electronic device to adjust the light source angle of the surface light source, that is, to adjust the angle between the first surface and the second surface.

Optionally, the electronic device may support the user to manually fold the first surface and the second surface, so as to adjust the light source angle of the surface light source.

It should be noted that, in the image capturing method provided by the embodiment of the present invention, since the light source parameters may include one or more of the light source brightness, light source color, light source shape, and light source angle, the electronic device can flexibly adjust and match the target camera. One or more of the light source brightness, light source color, light source shape, and light source angle of the corresponding surface light source improve the flexibility and accuracy of the fill light.

Optionally, when the target camera is the front camera of the electronic device, the surface light source corresponding to the target camera is realized through the first screen; when the target camera is the rear camera of the electronic device, the surface light source is passed through the electronic device. The rear shell is realized in the design.

Wherein, the rear shell of the electronic device may be a shell on the back of the electronic device.

Exemplarily, as shown in FIG. 3 , a schematic diagram of the distribution of surface light sources and cameras in an electronic device is provided for an embodiment of the present invention. Figure 3 shows a front view of the electronic device. 3 shows that the front of the electronic device includes a screen A1 and a screen A2, the screen A1 is located on the surface B1 of the electronic device, and the screen A2 is located on the surface B2 of the electronic device. Specifically, the front camera C is also included on the surface B2. The angle between surface B1 and surface B2 is α.

For example, when the front camera C is the target camera, the screen A1 is the surface light source corresponding to the target camera, the surface B1 is the first surface, and the surface B2 is the second surface. At this time, the light source brightness of the surface light source is the brightness of the bright screen area in screen A1, the light source color is the color of the bright screen area in screen A1, the light source shape is the shape of the bright screen area in screen A1, and the light source angle is α. For example, a may be 150 degrees.

Exemplarily, as shown in FIG. 4 , it is a schematic diagram of the distribution of surface light sources and cameras in an electronic device according to an embodiment of the present invention. Figure 4 shows a rear view of the electronic device. 4 shows that the electronic device includes a back D1 and a back D2, the back D1 includes a surface light source E, the back D2 includes a rear camera F, and the included angle between the back D1 and the back D2 is β. For example, β may be 150 degrees.

For example, when the rear camera F is the target camera, the surface light source E is the surface light source corresponding to the target camera, the back surface D1 is the first surface, and the back surface D2 is the second surface. At this time, the light source brightness of the surface light source is the brightness of the surface light source E, the light source color is the color of the surface light source E, the light source shape is the shape of the light emitting area in the surface light source E, and the light source angle is β.

3 and 4, the surface B1 and the back surface D1 are arranged opposite to each other, and the surface B2 is arranged opposite to the back surface D2.

In the embodiment of the present invention, since the surface light source corresponding to the target camera can be not only the screen of the electronic device, but also the surface light source set on the surface of the electronic device other than the screen, it is beneficial for the electronic device to be located in different positions. The camera is set to the corresponding surface light source. That is, it is possible to set the corresponding surface light source for the target camera, and further realize that the surface light source corresponding to the target camera is used to fill light for the shooting object of the target camera.

In a possible implementation, the image capturing method provided by the embodiment of the present invention may further include S204 before step 202:

S204. The electronic device displays the target setting option and/or the target control on the first screen, and displays the shooting preview interface of the target camera on the second screen.

Among them, the target setting option is used to set the light source parameters, the target control is used to trigger the surface light source to be turned on or off, and the shooting preview interface is used to preview and display the image captured by the target camera.

It can be understood that when a certain camera in the electronic device is running, the target setting options, target controls and shooting preview interface are all set for the surface light source corresponding to the camera.

Exemplarily, the screen A1 shown in FIG. 3 includes the “Auto Mode” option K1, the “Adjust Brightness” option K2, the “Adjust Color” option K3 and the “Adjust Light Source Shape” option K4, and the screen A2 includes the preview interface M1. The preview interface M1 is a preview interface of the front camera C, and the preview interface M1 includes a shooting control M11 , and the shooting control M11 is used to trigger the electronic device to shoot an image through the front camera C.

Wherein, after the user inputs the “adjust brightness” option K2 shown in FIG. 3 (such as click input), the electronic device as shown in FIG. 5 can display the brightness adjustment control K21 on the screen A1 to support the user to trigger the value Adjust the brightness between 0 and 100.

After the user inputs the “adjust color” option K3 shown in FIG. 3 (eg, click input), the electronic device as shown in FIG. Choose a color from Color as the light source color.
