碩士 === 國立成功大學 === 電機工程研究所 === 83 === In this thesis, the researches for realization of video scanning format conversion from NTSC to HDTV systems are engaged. The involved techniques include interlaced to progressive conversion(IPC), sampling rate conversion(SRC), line rate conversion(LRC), frame rate conversion(FRC) and aspect ratio conversion. The conversion algorithms utilized blockwise, motion detection, edge-preserving interpolation, and nonuniform aspect ratio conversion. The distortions and fatness of the picture by traditional conversion methods can be perceptually diminished. The simulation results show a very good quality by visual perception without any undesirable artifacts in the converted image sequences. For real time purposes, we also proposed an efficient architecture of the video scanning format conversion to implement the algorithm.
