Abstract

The invention is suitable for the field of image processing, and provides a method and a device for realizing multi-video signal image composition. The method comprises the following steps of: receiving image composition requirement information of a user; compositing multi-path images through multiple cascaded image synthesis plate cards according to the image composition requirement information; and receiving a composite image signal of the last stage of image composition plate card, and outputting a composite image signal code, wherein the image composition requirement information comprises a video input interface of each path of composite image, a picture composition mode as well as the position of each path of independent video image display in the picture composition mode. The device provided by the invention can expand composition numbers and paths at will, can support video input signals of different kinds, realizes the composition of an image with ultrahigh resolution, reduces the dependency on hardware, and realizes flexible allocation of multiple composite modes.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to a method and a device for synthesizing multiple video signal images. Background technique [0002] With the rapid development of video technology, Video Graphics Array (Video Graphics Array, VGA), Digital Visual Interface (Digital Visual Interface, DVI), Digital Serial Interface (Serial Digital Interface, SDI), High Definition Multimedia Interface (High Definition Multimedia Interface, HDMI), standard definition (Standard Definition, SD) and other different types of video signals and high-resolution application combinations are increasing, and various types of video images need to be displayed in a centralized manner. [0003] For video signals input by different interfaces, the methods currently used in image synthesis are: [0004] (1) Separately collect the signals from each video terminal, scale each signal to an appropriate size on the server side and combine the...
