Abstract

The invention provides an image processing method, an image processing device and terminal equipment. The method comprises the following steps of acquiring a plurality of images, and judging whether the images are shot in the same area or not; if the images are shot in the same area, determining an overlapped background region of the images; counting a color histogram of the overlapped backgroundregion; judging whether the overlapped background region is a preset pure-color background or not according to the color histogram; and if the overlapped background region is the preset pure-color background, selecting one image from the images, and carrying out white balance processing on the selected image according to the overlapping background region. According to the image processing method,the image processing device and the terminal equipment, a problem that the color cast of the processed image is too serious due to the traditional white balance algorithm when the image is provided with a large pure-color background is solved.

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...
