Abstract

The present invention relates to an image processing method and device, wherein the method includes: detecting the current brightness of the scene, and if it is detected that the brightness of the preset virtual background image is lower than the brightness of the scene, adding The virtual light source matches the brightness of the virtual background image with the brightness of the scene; obtains the scene image of the current user; obtains the depth image of the current user; processes the scene image and the depth image to extract the character area of ​​the current user in the scene image to obtain a character area image ; Merge the person area image with the virtual background image to obtain a merged image. Therefore, according to the difference between the virtual background and scene brightness, the virtual background image is supplemented with light, which avoids the excessive difference between the scene brightness and the virtual background image brightness, makes the fusion of the character area image and the virtual background image more natural, and improves the image quality. Handled visual effects.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and device. Background technique [0002] With the development of Internet technology, more and more communication functions have been developed and applied. Among them, the video communication function has been widely used because it can realize visual communication between users in different places. [0003] However, in the related art, in order to protect the privacy of the user, the scene information where the user is located is shielded with a virtual background when the user is performing a video chat. However, in practical applications, the brightness of the real scene information is usually different from the brightness of the virtual background. The gap is large, resulting in the fusion of the image of the character area and the virtual background image is relatively abrupt, and the visual effect is not good. Contents of the ...
