Abstract

The invention discloses an image white balance control method, and the method is used in electronic equipment. The method comprises the steps: obtaining a first image; obtaining the environmental parameter of the first image during photographing; carrying out the white balance adjustment of the first image based on the environmental parameter, and obtaining a second image corresponding to the first image. The method provided by the invention is used for solving technical problems in the prior art that the image white balance adjustment is lower in accuracy and is complex in process, thereby achieving the white balance adjustment of the image conveniently and accurately.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method for controlling image white balance and electronic equipment. Background technique [0002] When the human eye observes an object, it can adjust the color of the observed object according to the nature of the current light source, and this situation often occurs when shooting objects with electronic equipment. For example, the image shot in a fluorescent room will appear green, The scene shot under indoor tungsten light will be yellowish, while the photo taken in the shadow of sunlight will be blue, because the color temperature value of different light sources is different from the color temperature under normal light. [0003] During the photography process, when the user uses the automatic white balance mode in the photographic equipment, or when the environment is cloudy, but uses the sunny day white balance mode, it will lead to technical problems of inaccurate white...
