Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0036] Different from the prior art, in the embodiment of the present invention, the same control parameters and independently calculated adjustment coefficients are used to equalize the sub-picture video images from each single venue before forming multi-picture video images, so that the final formed The effects of multi-screen video images can all reflect the same characteristics.

[0037] Please refer to figure 1 , a schematic flowchart of a multi-picture ...

Abstract

The invention provides a method and a device for processing a multipicture video image, which solve the problem that the participants have poor visual experience because the characteristic of each sprite can not be simultaneously satisfied when the multiple pictures are adjusted in the traditional technical scheme. The method comprises the following steps of: receiving a data code stream of multiple sprite video images, and respectively balancing the effects of multiple sprite video images by using control parameters according to the characteristic of the picture video image; and synthesizing the balanced multiple sprite video images into a multipicture video picture. The invention can uniformly adjust each sprite video image to the same image characteristic effect, and then the sprite video image presents the same picture characteristic during displaying, therefore, the multipicture video image consisting of the sprite video images achieves the harmonious integral style and enhances the visual experience of the participants during displaying.

Description

technical field [0001] The invention relates to the field of video image processing, in particular to a multi-screen video image processing method and device. Background technique [0002] With the development of encoding and information compression technology and the rapid development of digital networks, video conferencing systems have begun to enter the market. The video conferencing system based on the H.323 video conferencing standard is getting more and more widely used along with the rapid development of IP network. The government, military, enterprises and other departments have basically deployed their own video conferencing systems to improve meeting efficiency and reduce meeting costs. [0003] The mode of video conferencing has developed from a single point-to-point call and a single screen displaying the video of the other party to the current conference mode in which multiple conferences are held at the same time, and multiple screens are displayed at the same...
