Embodiment Construction

[0060] The embodiment of the present application solves the technical problem in the prior art that more accurate white balance calibration cannot be performed on all common areas in an image by providing a method and electronic equipment for adjusting white balance.

[0061] In order to solve the above-mentioned technical problems in the embodiment of the present application, the general idea of ​​the technical solution adopted is as follows:

[0062] First, obtain N contour information of M image objects of an image to be calibrated, wherein, the M and N are both integers greater than or equal to 2, and N is less than or equal to M; this contour information can be embodied as a building, a car , sky, white clouds, playground, etc.; after obtaining the N contour information, and then based on the N contour information, obtain N of the N image objects corresponding to the N contour information among the M image objects White balance calibration parameters; after obtaining the ...

Abstract

The invention discloses a method of adjusting white balance, which is applied to electronic equipment. The method comprises steps of acquiring information of N profiles of M image objects of a to-be-corrected image, acquiring N white balance correction parameters of N image objects corresponding to information of N profiles in the M image objects on the basis of the information of N profiles, and carrying out white balance correction processing on the N image objects according to the N white balance correction parameters, wherein both M and N are integers no less than 2, and N is smaller than or equal to M. In addition, the invention also discloses the electronic equipment corresponding to the above method of adjusting white balance.

Description

technical field [0001] The invention relates to the fields of communication and electronics, in particular to a method for adjusting white balance and electronic equipment. Background technique [0002] With the continuous development of science and technology, cameras have also entered the era of digital cameras from film cameras. When shooting with digital cameras, it is often necessary to adjust the white balance parameters of the camera so that the photos taken are not distorted. The white balance parameters of the camera are not calibrated before, and it is necessary to use image processing software to calibrate the white balance of the photos after taking the photos. It can be seen that the white balance calibration is very important in the field of digital cameras. [0003] In the prior art, when performing white balance calibration on the image to be calibrated, the technical solution adopted is: perform gray point statistics on the entire frame of the image to be ca...
