Embodiment 1

[0031] figure 1 It is a schematic flow chart of a method for taking pictures based on screen fill light provided in Embodiment 1 of the present invention. The method can be executed by a camera device based on screen fill light. The device can be implemented by software and / or hardware, and can generally be integrated into a mobile in the terminal. Such as figure 1 As shown, the method includes:

[0032] Step 101. When it is detected that the screen fill-in light photography event is triggered, control the first display area located in the middle of the screen to perform fill-in light at the first brightness, and control the camera to capture the first image.

[0033] Exemplarily, the mobile terminal in this embodiment may specifically be a terminal device configured with a display screen, such as a mobile phone, a tablet computer, and a digital camera. The camera in this embodiment may specifically be a front-facing camera fixed on the front of the mobile terminal (on the ...

Embodiment 2

[0051] Figure 4 It is a schematic flow chart of a method of photographing based on screen supplementary light provided by Embodiment 2 of the present invention. This embodiment is optimized based on the above embodiments. In this embodiment, the step "controlling the first display area with the first Brightness fill light" is optimized as follows: determine the size of the face image in the preview interface of the screen through face recognition; determine the size of the first display area located in the middle of the screen according to the size of the face image; control the first display area to Fill light with the first brightness.

[0052] Further, the optimization of "controlling the second display area located around the screen to fill in light with the second brightness" can be: determine the size of the second display area located around the screen according to the size of the first display area; The second display area is supplemented with light at the second bri...

Embodiment 3

[0067] Figure 5 It is a schematic flow chart of a method of photographing based on screen fill light provided by Embodiment 3 of the present invention. This embodiment is optimized on the basis of the above embodiments. In this embodiment, the step "controlling the first display area with the first Brightness supplement light" is optimized as follows: determine the first brightness according to the ambient light brightness and the size of the face image; control the first display area to perform supplement light with the first brightness.

[0068] Further, the optimization of "controlling the second display area to perform supplementary light at the second brightness" is: determining the second brightness according to the brightness of the ambient light and the size of the face image; controlling the second display area to perform supplementary light at the second brightness.

[0069] Correspondingly, the method of this embodiment includes the following steps:

[0070] Step ...

Abstract

The embodiment of the invention discloses a photographing method and a photographing device based on screen light compensation and a mobile terminal. The method comprises the steps of when monitoring that a screen light compensation a photographing event is triggered, controlling a first display area in the middle position of a screen to compensate light with first luminance, and controlling a camera to capture a first image; controlling a second display area in the periphery of a screen to compensate light with second luminance, and controlling a camera to capture a second image, wherein the second luminance is higher than the first luminance; combining the first image with the second image, and then generating a photograph. By using the photographing method provided by the embodiment of the invention, light compensation and image capture are respectively performed on a human face and a background in a framing range, the photograph synthesized according to the two captured images is reasonable in luminance distribution, the photographing effect based on screen light compensation can be effectively improved, and the user experience can be enhanced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of photographing, and in particular, to a photographing method, device and mobile terminal based on screen fill light. Background technique [0002] At present, the camera has become the standard configuration of most mobile terminals. With the continuous improvement of the performance of the camera, the camera function in the mobile terminal is also becoming more and more powerful, which brings convenience to users who like to take pictures. [0003] Many mobile terminal users like to use the front camera on the mobile terminal to take selfies, but the front cameras of the existing mobile terminals are not equipped with fill lights, and it is difficult to take selfies at night or in poor light environments due to insufficient exposure. Get the ideal selfie effect. [0004] In order to obtain a proper exposure when the user takes a selfie, an existing solution is to light up the screen...
