Abstract

The invention discloses a method and a device for image rendering. The method comprises steps that: a target area is identified from an image to be rendered; a virtual light source is set for the target area; and the virtual light source is used to render the target area. The device comprises an identification unit, a setting unit and a rendering unit. The method and the device are utilized to render the image to be rendered, rendering for the image to be rendered is realized through the virtual light source, the virtual light source has a rendering effect only exerted on the corresponding target area, no influence is exerted on other parts of the image to be rendered, and thereby an image effect of the image to be rendered can be relatively excellent.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an image rendering method and device. Background technique [0002] Video conferencing system is a multimedia system that integrates voice, image, data and other information together for long-distance transmission. A video conferencing system generally consists of a video conferencing server and terminal equipment installed in each conference room, wherein the terminal equipment may include camera equipment, display equipment, and the like.
