Abstract

The invention relates to an image processing method and device. The method comprises the steps of detecting current scene brightness, if it is detected that preset brightness of a virtual background image is less than the scene brightness, adding a virtual light source in the virtual background image according to brightness difference between the virtual background image and the scene, so as to enable the brightness of the virtual background image to be matched with the scene brightness; acquiring a scene image of a current user; acquiring a depth image of the current user; processing the scene image and the depth image so as to extract a figure region of the current user in the scene image to acquire a figure region image; and fusing the figure region image with the virtual background image so as to obtain a combined image. Light is supplemented for the virtual background image according to the brightness difference between the virtual background image and the scene, so that the brightness difference between the scene and the virtual background image is not too high, the figure region image and the virtual background image are fused more naturally, and the visual effect of image processing is improved.

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 ...
