| Summary: | 碩士 === 國立交通大學 === 電子研究所 === 84 === In the thesis, MPEG2 output display unit for scan rate and
color spaceconversions is designed. A new up/down-sampling
filter structure is proposedto facilitate the conversion, which
can properly resize images in the scalerange of 1/4 and 4. The
scale range almost covers the wide specturm of existing video
standards including NTSC, H.261, PAL, SECAM, MPEG, LD, andmovie.
For design practice, we implement a video output interface for
MPEG2decoder. Its function is to synchronize the output picture
to the peripheraldevice; position the picture on the screen and
resize the selected part of the aspect ratio from 4:3 to 16:9.
Furthermore, the Kodak CCD-sensed image pixel processings, hue
interpolation and color correction are designed andintegrated.
The computation load is minimized without reduction of
imagequalities.
