Problems solved by technology

[0004] However, when the lighting conditions are not good, such as at night or in a low-light environment such as a dark room, or when the image acquisition equipment itself is likely to cause interference, such as video surveillance equipment, the color noise of the collected images, including face images, becomes more serious. outstanding, the effect of beautifying these images through the beautification technology of human face images in the prior art is relatively poor

Abstract

The invention provides an image processing method. The method comprises the steps that first image data are acquired, the first image data comprise a plurality of pixel coordinates of an image and RGBcolor data corresponding to the pixel coordinates, and modulation compensation is conducted on the first image data through single-channel modulation compensation information to obtain second image data. The single-channel modulation compensation information is used for compensating missing RGB color data in the first image data, color noise of the first image data is reduced, and a better beautifying effect can be provided for collected images including face images when the illumination condition is not good or image collection equipment is prone to interference.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method. Background technique [0002] With the continuous development of image processing technology, there are generally higher and higher requirements for the display effect of images, especially for the beautification effect of human face images. Therefore, how to optimize the display effect of images, especially images containing human faces, is a direction of continuous efforts in the field of image processing technology. [0003] In practical application scenarios, the lower the illumination and the higher the gain, the greater the intensity of the color noise of the image, as shown in Figure 1(a) and Figure 1(b), the color noise of Figure 1(a) The noise intensity is small, while the color noise intensity in Fig. 1(b) is relatively large, Fig. 1(a) is a schematic diagram of a human face image in the prior art, and Fig. 1(b) is a schemat...
