Abstract
이 발명은 영상 프로젝션 장치에 관한 것으로, 인가되는 CPU 어드레스와 제어 신호에 따라 다수 윈도우 영역에 해당하는 윈도우 ID 번호와 해당 영상 데이터를 억세스하기 위한 어드레스를 출력하는 어드레스 발생 수단과; 인가되는 제어 신호에 따라 상기 어드레스 발생수단에서 출력되는 어드레스에 저장된 해당 윈도우 ID 번호를 출력하거나 저장하는 윈도우 메모리와; 인가되는 제어 신호에 따라 상기 어드레스 발생 수단에서 출력되는 어드레스에 저장된 해당 영상 데이터를 출력하거나 저장하는 영상 메모리와; 상기 윈도우 메모리에서 출력되는 데이터와 인가되는 CPU 어드레스중 하나를 선택하여 프로젝션 어드레스로 출력하는 선택 수단과; 상기 선택 수단에서 출력되는 프로젝션 어드레스에 저장된 해당 프로젝션 데이터를 출력하거나 저장하는 프로젝션 메모리와; 인가되는 제어 신호에 따라 상기 프로젝션 메모리에서 출력되는 프로젝션 데이터와 상기 영상 메모리에서 출력되는 영상 데이터를 래치하여 가산시킨 다음 출력하는 가산 및 래치 수단을 포함하여 이루어지며, 실시간 영상 데이터 처리가 요구되는 화상 시스템에 있어서 다수 윈도우 영역의 영상 데이터를 처리하는 경우에, 한 번의 스캔 동작시에 해당 영상 데이터 및 영상 좌표와 동시에 설정된 영상 윈도우 번호를 출력함으로써, 다수 윈도우 영역의 영상을 신속하게 처리할 수 있다.The present invention relates to an image projection apparatus, comprising: address generating means for outputting a window ID number corresponding to a plurality of window regions and an address for accessing corresponding image data according to an applied CPU address and a control signal; A window memory for outputting or storing a corresponding window ID number stored at an address output from the address generating means according to an applied control signal; An image memory for outputting or storing corresponding image data stored at an address output from said address generating means in accordance with an applied control signal; Selecting means for selecting one of the data output from the window memory and the CPU address to be output to the projection address; A projection memory for outputting or storing corresponding projection data stored in the projection address output from the selecting means; And an addition and latch means for latching, adding, and outputting projection data output from the projection memory and image data output from the image memory according to an applied control signal, and real-time image data processing is required. In the case of processing image data of a plurality of window regions, the image window number set at the same time as the image data and image coordinates is output in one scan operation, so that the image of the plurality of window regions can be processed quickly.
