Problems solved by technology

However, many mobile terminal users now like to use the front camera on the mobile terminal to take selfies. The front cameras of the existing mobile terminals are not equipped with fill lights. selfie effect
[0004] In order to obtain a proper exposure when the user takes a selfie, an existing solution is to increase the brightness of the screen to fill in the light for the front camera and take a photo. However, the light fill effect of the existing solution is not ideal and cannot meet the needs of users

Embodiment 1

[0026] figure 1 It is a schematic flowchart of a method for taking pictures with screen fill light provided in Embodiment 1 of the present invention. The method can be executed by a device for taking pictures with screen fill light, wherein the device can be realized by software and / or hardware, and generally can be integrated in a mobile terminal. Such as figure 1 As shown, the method includes:

[0027] Step 101 , when it is detected that the screen fill-in light photography event is triggered, control the screen to perform pre-fill light at the first brightness.

[0028] 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 same side as the screen), or a rotatable camera whose current position is on the front of the mobi...

Embodiment 2

[0044] figure 2 It is a schematic flowchart of a method for taking pictures with screen fill light provided by Embodiment 2 of the present invention. This embodiment is optimized based on the above embodiments. In this embodiment, the first brightness and the second brightness are refined: The first brightness is within the system default brightness adjustment range of the screen, and the second brightness is greater than the maximum brightness of the system default brightness adjustment range and less than or equal to the maximum brightness supported by the screen.

[0045] Further, controlling the screen to perform main supplementary light at the second brightness until the camera ends image capture may specifically include: switching the brightness adjustment range of the screen from the system default brightness adjustment range to the maximum adjustment range supported by the screen; controlling the screen to The second brightness is the main supplementary light until th...

Embodiment 3

[0060] image 3 A schematic flow chart of a preferred method for taking pictures with screen fill light provided in Embodiment 3 of the present invention, as shown in image 3 As shown, the method includes the following steps:

[0061] Step 301, the front-facing camera in the mobile terminal is turned on.

[0062] Step 302 , judging whether the screen fill light function is enabled, if yes, execute step 303 ; otherwise, execute step 309 .

[0063] Step 303 , judging whether the current ambient light brightness is lower than a preset brightness threshold, if yes, execute step 304 ; otherwise, execute step 309 .

[0064] Step 304 , when it is detected that the camera button is triggered, control the screen to perform pre-fill light with the first brightness.

[0065] In this embodiment, the first brightness is the maximum brightness of the default brightness adjustment range of the system, and the second brightness is the maximum brightness supported by the screen.

Abstract

The embodiment of the invention discloses a method, a device and a mobile terminal for taking pictures with screen fill light. The method includes: when it is detected that the screen fill light photo event is triggered, controlling the screen to perform pre-fill light with a first brightness; controlling the camera to start continuously capturing images during the pre-fill light process; controlling the screen to perform main fill light with a second brightness until The camera ends image capture, wherein the second brightness is different from the first brightness; at least one frame of target image is selected from the captured images, and a photo is generated according to at least one frame of target image. In the embodiment of the present invention, by adopting the above-mentioned technical scheme, the fill-in light stage is divided into two stages: pre-fill light and main fill-in light. Each stage corresponds to a different screen brightness. The camera can capture more images with different fill light effects, which expands the selection range of target images and improves the quality of photos.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of mobile terminals, and in particular, to a method and device for taking pictures with screen fill light and a mobile terminal. 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] There are many shooting scenes that users choose, often including karaoke room (KTV) and streets at night. It can show more real scenes, rather than a dark scene. However, many mobile terminal users now like to use the front camera on the mobile terminal to take selfies. The front cameras of the existing mobile terminals are not equipped with fill lights. selfie effect. [0004] In order to obtain a proper exposure when the us...
