Amultiplierless Letter-box converter using 4:3 decimation algorithm

4:3 데시메이션 알고리즘을 이용한 멀티플라이어리스 레터박스 변환기

This paper proposes a efficient algorithm of letter-box converter using 4:3 decimation algorithm. To display 16:9 wide images on a 4:3 screen, there is need to convert the 16:9 wide images. The letter-box converter is designed with multiplierless architecture. We have modeled the letter-box converter in verilog-HDL and verified to show little difference between the original image and the converte image.
