Embodiment 1

[0042] The image processing method provided by Embodiment 1 of the present application is described below, please refer to the attached figure 1 , the image processing method in Embodiment 1 of the present application includes:

[0043] In step S101, a plurality of images are acquired, and it is judged whether the above-mentioned plurality of images are images taken in the same area;

[0044] In Embodiment 1 of the present application, multiple images are acquired first, and the multiple images may be multiple images automatically selected from the photo album of the terminal device; or, it may also be multiple images manually selected by the user from the photo album, or , may also be multiple images automatically captured by the terminal device at the same time when receiving a user's shooting instruction, and how to acquire multiple images is not limited here.

[0045] After acquiring multiple images, it is necessary to determine whether the multiple images are images take...

Embodiment 2

[0075] The image processing method provided by Embodiment 2 of the present application is described below, please refer to the attached image 3 , the image processing method of Embodiment 2 of the present application includes:

[0076] In step S301, a plurality of images are acquired, and it is judged whether the above-mentioned plurality of images are images taken in the same area;

[0077] In step S302, if the multiple images are images taken in the same area, then determine the overlapping background area of ​​the multiple images;

[0078] In step S303, the color histogram of the above-mentioned overlapping background area is counted;

[0079] In step S304, according to the color histogram, it is judged whether the overlapping background area is a preset solid color background;

[0080] In Embodiment 2 of the present application, the above steps S301-S304 are the same as Steps S101-S104 in Embodiment 1. For details, please refer to the description of Embodiment 1, which ...

Abstract

The present application provides an image processing method, an image processing device, and a terminal device. The method includes: acquiring multiple images, and judging whether the multiple images are images taken in the same area; if the multiple images are For images taken in the same area, determine the overlapping background areas of the multiple images; count the color histogram of the overlapping background area; judge whether the overlapping background area is a preset solid color background according to the color histogram ; If the overlapping background area is a preset solid-color background, select an image from the plurality of images, and perform white balance processing on the selected image according to the overlapping background area. The present application can solve the problem that the color cast of the processed image caused by the traditional white balance algorithm is too serious when the image has a large solid color background.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to an image processing method, an image processing device, a terminal device, and a computer-readable storage medium. Background technique [0002] At present, the terminal device must perform white balance processing on the captured image after taking pictures. Yellowish below, bluish in sunlight shadows. [0003] The traditional white balance algorithm first needs to estimate the color temperature of the current environment according to the captured image, and then perform white balance processing on the captured image according to the estimated color temperature. However, when the captured image has a large solid color background, such as a large blue or yellow background, the traditional white balance algorithm will fail. For example, when there is a large blue background in the captured image, the traditional white balance algorithm will recogni...
