Detailed ways

The technical solutions in the embodiments of the present application are clearly and completely described in the following with reference to the drawings in the embodiments of the present application. It is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

With the increasing demand for photo quality of mobile terminals such as mobile phones and tablet computers, flash units are set in more mobile terminals. The flash is a tool that can emit light in a short time and fill the image collection environment during image capture and video recording.

Usually the mobile terminal will set up two cameras. Among them, the camera disposed on the same side as the screen is referred to as a front camera, and the camera disposed on the side opposite to the screen becomes a rear camera. The flash in the mobile terminal is usually disposed on the same side as the rear camera, so that the rear camera fills the light during the image acquisition process. In addition, the mobile terminal may also separately set a screen on the front and rear sides, the screen set on the front side as the first screen, and the screen set on the back side as the second screen, in this case, the front camera Set on the side of the first screen, the flash and rear camera are set on the side of the second screen.

However, the inventors found that the light supplemented by the flash lamp is usually strong and not soft enough, resulting in poor quality of the photograph taken.

Therefore, the inventors have proposed an image capturing method, apparatus, mobile terminal, and storage medium that improve the light supplemented by the flash, which is not soft enough to cause poor quality of the photograph taken.

Embodiments of the present application will be specifically described below with reference to the accompanying drawings.

Referring to FIG. 1 , an image collection method provided by the present application is applied to a mobile terminal, where the mobile terminal includes a front side and a back side, the front side is provided with a first screen, and the back side is provided with a camera and a second screen; The methods include:

Step S110: When detecting that the camera is activated, displaying an image acquired by the camera in real time on the first screen.

Step S120: When the shooting instruction is detected, the second screen is displayed at a preset brightness.

As a way, for objects of different distances, the second screen can be displayed with different brightness. In this case, when the mobile terminal detects the shooting instruction, the distance between the target and the object is acquired; and the second screen is caused by the preset brightness corresponding to the distance according to the pre-established distance and brightness mapping relationship. Displaying, wherein, in the distance-luminance mapping relationship, the brightness corresponding to the larger value is larger.

As a way, when a shooting instruction is detected, the second screen is caused to display a picture of a predetermined brightness. In addition, when displaying the picture of the preset brightness, the second screen may display a picture of the preset brightness corresponding to the light intensity according to the pre-established mapping relationship between the light intensity and the brightness, wherein In the relationship between light intensity and brightness, the higher the intensity value, the smaller the brightness corresponding to the light intensity.

Step S130: Store the image captured by the camera during the display of the second screen with a preset brightness.

An image acquisition method provided by the present application, when detecting that the camera is activated, displaying an image captured by the camera in real time on the first screen, and then, when detecting a shooting instruction, making the second screen preset The brightness is displayed to store at least one of the second screens for displaying the image captured by the camera during the display with a preset brightness, so that the light is displayed by the second screen at a preset brightness, thereby avoiding the light filling, thereby avoiding The problem of poor quality of the photographs taken is caused by the fill light of the flash being too strong.

Referring to FIG. 2, an image collection method provided by the present application is applied to a mobile terminal, where the mobile terminal includes a front side and a back side, the front side is provided with a first screen, and the back side is provided with a camera and a second screen; The methods include:

Step S210: When detecting that the camera is activated, displaying an image acquired by the camera in real time on the first screen.

After the camera is started, the image can be collected in real time, and after detecting that the camera is activated, the mobile terminal continuously caches the image captured by the camera in real time, and displays the image captured by the camera in real time on the first screen, so that the user can preview in real time.

Step S220: When the shooting instruction is detected, the current fill mode is determined.

The mobile terminal provided by the present application can control the flash to start to fill light, and can also control the second screen to display a picture of a preset brightness to fill light. Specifically, when the fill light mode is the flash fill light, the mobile terminal controls the flash to start when the shooting instruction is detected, and when the fill light mode is the screen fill light, the control screen displays the preset brightness picture to fill the light. Then, when the mobile terminal detects the shooting instruction, it can determine the current fill mode to subsequently fill the light according to the current fill mode.

Among them, as a way, the fill light mode can be manually set by the user. When it is detected that the virtual setting button displayed in the first screen is touched, a setting interface is popped up, and in the setting interface, the user can set the mobile terminal to collect the screen fill light or the flash fill light. For example, as shown in FIG. 3, an adjacent control interface 20 and a camera real-time image display interface 30 are displayed in the first screen. When the mobile terminal detects that the fill mode control button 22 in the control interface 20 is touched, The setting interface 23 is suspended in the image display interface 30. The display setting interface 23 includes a flash mode button 231 and a screen fill mode button 232. When the user clicks the flash mode button 231, the mobile terminal sets the current fill mode to flash fill light. When the user clicks the flash mode button 232, the mobile terminal sets the current fill mode to screen fill light. In addition, the fill light mode can also be set according to data collected by sensors included in the mobile terminal. For example, when the mobile terminal sets the distance sensor on the side of the second screen, the mobile terminal determines that the fill light mode is the flash fill light when detecting that the distance sensor detects the object within the preset range. The distance sensor may be an infrared sensor or a proximity light sensor.

Step S230: When the fill light mode is determined to be a flash fill light, the flash is activated.

Step S240: Store an image acquired by the camera during the flash startup.

Step S250: When it is determined that the fill light mode is the screen fill light, the second screen is caused to display a picture of a preset brightness.

The preset brightness may be a preset brightness, for example, a brightness manually set by the user in the brightness setting interface. It can also be a picture of the preset brightness corresponding to the current light intensity. As a method, when it is determined that the fill light mode is the screen fill light, the light intensity is obtained; and the second screen displays a picture of the preset brightness corresponding to the light intensity, wherein the preset brightness and the The intensity of the light is inversely proportional, so that in the environment where the ambient light is darker, the picture with higher brightness is displayed, so as to achieve sufficient fill light and improve the quality of picture shooting.

As a way, the color of the displayed picture of the preset brightness may be white. The white picture is a picture in which all pixel points have an RGB value of 255. At the same brightness, the white picture can add the strongest light, which can make a better fill light. In addition, as another way, the picture displayed by the mobile terminal on the second screen may further include a combination of white and other colors. For example, as shown in FIG. 4, the picture includes three areas of D1, D2, and D3. Among them, the D1 and D3 areas display white, and the D2 area displays black, so that the D1 and D3 areas are respectively oppositely set light source centers, thereby achieving more uniform illumination of the environment.

It should be noted that the colors specifically displayed by the three regions D1, D2, and D3 are not specifically limited in the present application, as long as the colors displayed in the D1 and D3 regions belong to a bright color system, and the colors displayed in the D2 region are dark colors. . Further, as a way of improving the interestingness of shooting, the displayed picture of the preset brightness includes a plurality of areas, and at least two of the plurality of areas have different colors. As shown in FIG. 5, the picture displayed on the second screen includes two areas D4 and D5, and the two areas D4 and D5 respectively display pictures of different colors.

Step S260: Store an image collected by the camera during the second screen display of the picture.

The image collection method provided by the present application detects that when the camera is activated, when the fill light mode is determined to be a screen fill light, the image captured by the camera in real time is displayed on the first screen, and then a shooting instruction is detected. And causing the second screen to display a picture of a preset brightness, so as to store at least one image captured by the camera during the displaying of the picture on the second screen, so that a picture with a certain brightness is displayed through the second screen. The way to achieve fill light avoids the problem of poor quality of the photos taken because the flash fills too much.

Referring to FIG. 6 , an image acquisition method provided by the present application is applied to a mobile terminal, where the mobile terminal includes a camera, a first screen and a second screen that are oppositely disposed, and the camera and the second screen are disposed in the The same side of the mobile terminal; the method includes:

Step S310: When detecting that the camera is activated, displaying an image acquired by the camera in real time on the first screen.

Step S320: When the shooting instruction is detected, the second screen is caused to display a picture of a preset brightness.

Step S330: Store an image collected by the camera during the second screen display of the picture.

Step S340: Lighting the flash.

Step S350: storing at least one image captured by the camera during the flashing of the flash;

Step S360: superimposing and synthesizing the image captured by the camera during the flashing of the flash with the image captured by the camera during the second screen displaying the image.

In order to facilitate the subsequent description, in the present application, the image captured by the camera during the flashing of the flash is used as the image P1, and the image captured by the camera during the second screen is displayed as the image P2.

As one way, the luminance values of the image P1 and the image P2 are superimposed and combined. For example, when a certain object is photographed, in the case where the flash is lit to fill light, the overall brightness of the stored picture is higher than the brightness of the entire picture stored in the case of using the screen fill light. However, in the case of using the flash to fill light, the target area in the stored picture usually has a brighter spot, that is, in the case where there is a target in the captured image, in the obtained image P1, There will be brighter spots in the target area. Then, as a superposition and synthesis method, the image of the target region in the image P1 is switched to the image of the target region in the image P2, so that the overall brightness of the synthesized image is more uniform. In this case, the brightness of the spot in the target can be effectively reduced, and the brightness of the area other than the target can be made strong so that the user can see clearly.

As shown in FIG. 7, the target object in the image P1 is M1, and the area 361 is the area where the target object M1 recognized by the mobile terminal is located, that is, the target object area formed as described above, and the area 362 is an area other than the target object. As shown in FIG. 8, in the image P2, the target is M1, and the area 363 is the area where the target M1 recognized by the mobile terminal is located, and the area 364 is the area other than the target.

Here, the area of the area 361 and the position in the image P1 are the same as the area of the area 363 and the position in the image P2 so that the subsequent superposition coincides. Wherein, the target object in the area 361 has a certain spot due to the strong flash light, which affects the picture quality, and the brightness in the area 361 is stronger than the brightness in the area 363, and the brightness in the area 362 is stronger than the area. Brightness in 364. Then, the area 361 and the area 364 are superimposed and combined to form a final picture, so that the overall brightness of the superimposed synthesized picture is relatively uniform. It should be noted that the target object M1 may be a foreground object in the image, or may be a preset object existing in the detected image, such as a human face. The target area is an area that can completely surround the foreground object or the preset object.

An image acquisition method provided by the present application, when detecting that the camera is activated, displaying an image captured by the camera in real time on the first screen, and then displaying the second screen when the shooting instruction is detected Setting a picture of the brightness to store at least one image captured by the camera during the displaying of the picture on the second screen, and then storing an image captured by the camera during the lighting of the flash, The image captured by the camera during flashing is superimposed with the image captured by the camera during the second screen display of the image to obtain a final image, thereby avoiding shooting due to too strong fill light of the flash. The problem of poor quality photos.
