Abstract

본 발명은 라인 메모리를 이용한 영상미러 장치에 관한 것으로서, 영상을 구성하는 하나의 라인에 해당하는 화소데이터를 저장하는 제1라인메모리; 제1라인메모리에 저장된 영상데이터의 다음 라인에 해당하는 데이터를 저장하는 제2라인메모리; 제1라인메모리 또는 제2라인메모리의 쓰기어드레스를 발생하는 쓰기어드레스발생기; 제1라인메모리 또는 제2라인메모리의 읽기 어드레스를 발생하는 읽기어드레스 발생기; 쓰기어드레스 발생기에서 출력되는 쓰기 어드레스, 일기어드레스 발생기에서 출력되는 읽기 어드레스 중 하나를 선택하여 제1라인메모리로 출력하는 제1선택기; 쓰기어드레스 발생기에서 출력되는 쓰기 어드레스, 읽기어드레스 발생기에서 출력되는 읽기 어드레스 중 하나를 선택하여 제2라인메모리로 출력하는 제2선택기; 및 제1라인메모리, 제2라인메모리로 출력 데이터 중 하나를 선택하여 출력하는 데이터출력 선택기를 포함함을 특징으로 한다.The present invention relates to an image mirror apparatus using a line memory, comprising: a first line memory configured to store pixel data corresponding to one line constituting an image; A second line memory for storing data corresponding to a next line of image data stored in the first line memory; A write address generator for generating a write address of the first line memory or the second line memory; A read address generator for generating a read address of the first line memory or the second line memory; A first selector for selecting one of a write address output from the write address generator and a read address output from the diary address generator and outputting the selected address to the first line memory; A second selector for selecting one of a write address output from the write address generator and a read address output from the read address generator and outputting the selected address to the second line memory; And a data output selector for selecting and outputting one of the output data to the first line memory and the second line memory.

본 발명에 의하면 어드레스 제어를 통해 영상 미러를 구현하는데 2개의 필드메모리를 사용하는 대신 크기가 훨씬 작은 라인 메모리 2개만으로도 영상미러를 구현할 수 있다.According to the present invention, instead of using two field memories to implement an image mirror through address control, an image mirror can be implemented using only two line memories having a much smaller size.
