HARDWARE DESIGN OF A SCAN CONVERTER USING SPLINE INTERPOLATION
스플라인 보간법을 적용한 스캔 변환기의 하드웨어 구현
Abstract
The purpose of format conversion is to convert a wide range of personal computer video formats into a target format. Circuits for the conversion have been developed by means of interpolation techniques, such as zero-order interpolation, bilinear interpolation, and bisigmoidal interpolation. This paper proposes a scan converter using cubic splines. The converter was modeled in VHDL on Max+PlusII and implemented with an FPGA chip. The circuit gives much better conversion performance than a scan converter with zero-order or linear interpolation.
