Jj. Lee et al., DESIGN OF A SCAN FORMAT CONVERTER USING THE BISIGMOIDAL INTERPOLATION, IEEE transactions on consumer electronics, 44(3), 1998, pp. 1115-1121
This paper describes a circuit that converts a wide range of personal
computer video formats to a target format. The conversion is based on
the bisigmoidal interpolation, and look-up tables are used for efficie
nt hardware implementation of that interpolation. The scan converter w
as modeled in VHDL and implemented as a single chip in a 0.6 mu m CMOS
semiconductor process.
