Abstract

The present invention relates to an image processing method and device, wherein the method includes: obtaining component elements of the scene where the current user is located, and processing the component elements according to preset image parameters to generate a virtual background image; if it is detected that the brightness of the virtual background image is lower than that of the scene Brightness, simulate the sound of turning on the lights, and add a virtual light source to the virtual background image according to the brightness difference between the two, so that the brightness of the virtual background image matches the scene brightness; obtain the scene image and depth image of the current user; obtain the character area image and fused with the virtual background image to obtain a merged image. As a result, the virtual background image is supplemented with light according to the difference between the virtual background and the scene brightness, 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. The visual effect of the processing, and the sound of turning on the light is simulated when the light is filled, which increases the reality of the light fill and realizes the interaction with the user.

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 ...
