Problems solved by technology

However, in actual scenes, there are often two or more light sources. If the above-mentioned algorithm for one light source is used for adjustment, the color adjustment of the light source can be completed, but the area of ​​the other one or more light sources will still remain There is color deviation, and there is still color deviation in the entire image, which affects the imaging effect of the image

Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] The image processing method and device provided by the embodiments of the present invention can be applied to a scene where a camera is used to take pictures to generate images. Each light source corresponds to the distribution area of ​​each light source, and the white balance algorithm corresponding to each light source is used to process the target image separately to generate at least two frames of processed images. One light source corresponds to on...

Abstract

The embodiment of the invention discloses an image processing method and device. The method comprises the following steps: when the fact that a target image includes at least two light sources is detected, determining the distribution area corresponding to each light source in the at least two light sources; respectively processing the target image by using a white balance algorithm corresponding to each light source, generating at least two frames of processed images, wherein one light source corresponds to one frame of processed image; according to the distribution area corresponding to each light source, synthesizing the at least two frames of processed images into one image, and outputting the image. The method can reduce the color deviation of images under multiple light sources.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to an image processing method and device. Background technique [0002] In daily life, people will record every bit of life through the camera, but before the image captured by the camera is processed by the white balance, there will be a color cast phenomenon under different color temperature light sources. Color deviation caused by color temperature. For the case that there is one light source in the whole image, the deviation of the image is kept constant, and the white balance of the image is adjusted by calculating the white balance gain value of the whole image. However, in actual scenes, there are often two or more light sources. If the above-mentioned algorithm for one light source is used for adjustment, the color adjustment of the light source can be completed, but the area of ​​the other one or more light sources will still remain There is color deviation, a...
