Abstract

실시간 처리가 가능한 영상 모자이크 시스템을 개시한다. 비디오 입력신호를 입력으로 하는 영상 모자이크 시스템; 상기 비디오 입력 신호와 상기 영상 모자이크 시스템의 출력을 입력으로 하여 선택적으로 출력하는 멀티플렉서; 모자이크 윈도우 위치와 크기신호를 입력으로 하는 메모리; 모자이크 대상의 움직임을 보상하는 움직임 보상회로; 상기 메모리와 상기 움직임 보상회로의 출력을 합성하여 상기 메모리에 피드백하는 가산기; 및 상기 가산기의 출력, 샘플링 클럭, 수평동기신호 및 수직동기신호를 입력으로 하여 상기 멀티플렉서의 선택신호를 출력하는 윈도우 검출 회로를 포함하는 것을 특징으로 하는 실사간 영상 모자이크 시스템을 제공한다.A video mosaic system capable of real time processing is disclosed. An image mosaic system which receives a video input signal; A multiplexer for selectively outputting the video input signal and the output of the image mosaic system as inputs; A memory for inputting a mosaic window position and a magnitude signal; A motion compensation circuit for compensating for the movement of the mosaic object; An adder for synthesizing the outputs of the memory and the motion compensation circuit and feeding them back to the memory; And a window detection circuit for outputting a select signal of the multiplexer by inputting an output of the adder, a sampling clock, a horizontal synchronization signal, and a vertical synchronization signal.

본 발명도에 의하면, 사용자가 모자이크하고자 하는 윈도우를 지정하면, 움직임 보상회로에서 윈도우의 움직임을 검출 보상함으로써 실시간으로 영상의 움직임에 따라 효율적인 영상 모자이크가 가능한 영상 모자이크 시스템을 얻을 수 있다.According to the present invention, if the user designates a window to be mosaiced, the motion compensation circuit detects and compensates for the movement of the window to obtain an image mosaic system capable of efficient image mosaic according to the motion of the image in real time.
