Embodiment 1

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

[0027] Step 101, when it is detected that a screen fill light event is triggered, determine a preview area and a fill light area on the screen.

[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.

[0029] figure 2 It is a schematic diagram of an existing screen fill-in light process provided by Embodiment 1 of the present invention. Before the screen fill-in light event is triggered, a preview area, a camera key and some camera setting buttons will be displayed on the screen. Th...

Embodiment 2

[0039] Image 6 It is a schematic flow chart of a method for supplementing light on a screen provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiments. In this embodiment, the step "determine the preview area and fill light area on the screen" The optimization is as follows: determine the preview area in the screen, and determine the supplementary light area from the areas in the screen other than the preview area.

[0040] Exemplarily, the supplementary light area determined from the area of ​​the screen other than the preview area may be a partial area in the area other than the preview area, may be a continuous area, or may be several discontinuous areas. Preferably, an area of ​​the screen other than the preview area is determined as the supplementary light area.

[0041] Further, the "determining the preview area on the screen" can also be optimized as: controlling the camera to capture the cached imag...

Embodiment 3

[0057] Figure 7 It is a schematic flowchart of a method for supplementing light on a screen provided by Embodiment 3 of the present invention. This embodiment is optimized on the basis of the above embodiments. In this embodiment, the optimization of "determining the preview area on the screen" is: control the camera Capture the cached image in real time; for each captured cached image, determine the coordinates of the face image contained in the current cached image, and determine the current preview area on the screen according to the coordinates of the face image and the preset preview area size rule. This method is especially suitable for the situation that only human faces are included in the photo preview image.

[0058] Correspondingly, the method of this embodiment includes the following steps:

[0059] In step 701, it is detected that a screen fill light event is triggered.

[0060] Step 702, controlling the camera to capture buffered images.

[0061] Step 703: De...

Abstract

The embodiment of the invention discloses a method, a device and a mobile terminal for supplementing light on a screen. The method includes: determining a preview area and a light supplement area on the screen when a screen supplement light event is detected; controlling the supplement light area to display a supplement light image, and controlling the preview area to display a photo preview image in real time. In the embodiment of the present invention, by adopting the above-mentioned technical solution, when it is necessary to supplement the light for the Selfie through the screen, the preview area and the supplementary light area are divided from the display area of ​​the entire screen, and the supplementary light image is displayed by the supplementary light area. At the same time, the preview area The photo preview image is displayed in real time, and the user can predict the photo shooting effect after the light is filled by viewing the photo preview image, which is convenient for the user to make corresponding adjustments to his expression, shooting angle, shooting distance, and photo brightness, etc., and take pictures that he is satisfied with. photos to improve user experience.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of photographing, and in particular, to a method, device and mobile terminal for supplementing light on a screen. Background technique [0002] At present, mobile terminals such as mobile phones and tablet computers are mostly equipped with front cameras, so that mobile terminal users can easily take selfies. However, the front cameras of the existing mobile terminals are not equipped with supplementary lights, and it is difficult to obtain an ideal self-portrait effect due to insufficient exposure when taking self-portraits at night or in an environment with poor light. [0003] In order to obtain a suitable exposure when the user takes a selfie, an existing solution is to fill in light for the front camera by controlling the display screen to display a solid color image with an appropriate brightness when taking the selfie. However, the existing solutions have the following problems:...
