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.
