Embodiment 1

[0045] What is described in Embodiment 1 is to collect two images with different brightness, and then according to the object image information contained in the images (such as the brightness value of the image) and the background image information (such as the background brightness value) of the electronic device when capturing the image, To determine whether each image needs to be supplemented with light, and calculate the required fill light value of the image, and then adjust the brightness value of the image to the best state according to the fill light value, please refer to figure 1 ,include:

[0046] S101. Acquire first image information and second image information.

[0047] Wherein, the first image information includes first object image information and first background image information of the shooting object, and the second image information includes second object image information and second background image information of the shooting object.

[0048] For exampl...

Embodiment 2

[0100] In the embodiment of this application, it is described that three or more images with different brightnesses are collected, and then according to the object image information contained in the images (such as the brightness value of the image), and the background image information ( For example, the background brightness value), to determine whether each image needs to be filled with light, and calculate the required fill light value of the image, and then adjust the brightness value of the image to the best state according to the fill light value.

[0101] First, the electronic device collects three images and uses the information in the three images to calculate and adjust the fill light value.

[0102] When the electronic device obtains the first image information and the second image information image, and after judging whether the first image information and the second image information meet the preset threshold, it also obtains the third image information, wherein t...

Embodiment 3

[0186] The embodiment of the present application also provides an electronic device, such as Figure 11 shown, including:

[0187] An acquiring unit, configured to acquire first image information and second image information, wherein the first image information includes first object image information and first background image information of the object to be photographed, and the second image information includes second object image of the object to be photographed information and the second background image information.

[0188] The judging unit 10 is configured to judge whether the first image information and the second image information satisfy a preset threshold.

[0189] The analysis unit 11 is configured to perform brightness analysis on the first image information and the second image information to obtain a first analysis result when the determination result is negative.

[0190] The adjustment unit 12 is configured to adjust the brightness value corresponding to the...

Abstract

The present application provides a method for adjusting brightness, which is applied to an electronic device, including: acquiring first image information and second image information, wherein the first image information includes first object image information and a first background image of an object to be photographed Information, the second image information includes the second object image information and the second background image information of the photographed object; judge whether the first image information and the second image information meet a preset threshold; when the judgment result If it is no, perform brightness analysis on the first image information and the second image information to obtain a first analysis result; according to the first analysis result, the brightness value and \ Or the brightness value corresponding to the second background image information is adjusted.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method for adjusting brightness. Background technique [0002] In the prior art, due to the continuous development of electronic technology, electronic devices (such as all-in-one machines or PADs) have more and more functions. For example, electronic devices can be used to take pictures of objects. When using electronic devices to take pictures of objects, Firstly, the object is placed in front of the screen of the electronic device, and then the camera device on the electronic device or an external camera device is used to take pictures of the object, and the photographed data is stored in the electronic device. [0003] However, during the process of implementing the present application, the applicant found that the prior art has at least the following technical problems: [0004] When using the built-in camera device on the electronic device or an external camera devic...
