Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] It can be understood that the terms "first", "second" and the like used in the present invention can be used to describe various elements herein, but these elements are not limited by these terms. These terms are only used to distinguish one element from another element. For example, a first statistical unit could be termed a second statistical unit, and, similarly, a second statistical unit could be termed a first statistical unit, without departing from the scope of the present invention. Both the first statistical unit and the second statistical unit are statistical units, but they are n...

Abstract

The invention relates to a white balance processing method and device and a computer device. The method includes the following steps: conducting face recognition on an image to recognize a face area and a background area except the face area; obtaining a reference area in the face area, wherein the reference area is a white area in an object; performing white balance processing on the whole image on the basis of the reference area or performing white balance processing on the face area on the basis of the reference area; and performing white balance processing on areas except the face area according to the background area. White balance processing can be conducted on the image according to the specific reference area in the face area of the image, so the white balance accuracy is increased, and the user experience is improved.

Description

technical field [0001] The invention relates to image processing technology, in particular to a white balance processing method, device and computer equipment. Background technique [0002] Color Temperature is a measure of the light color of a light source, and the unit is K (Kelvin). The human eye perceives the brightest objects as white at any color temperature. The photos taken by the camera at different color temperatures show different colors, for example, the photos under the D65 light source are bluish, while the photos under the A light are yellowish. Indoor light sources are often more complicated, and the color temperature of incandescent lamps and fluorescent lamps is not very standard. Therefore, shooting portraits indoors often leads to abnormal skin tones, yellowish or bluish. [0003] With the development of image processing technology, people have higher and higher requirements for images, and usually post-optimize images to obtain better visual effects. ...
