FUNCTIONAL DESCRIPTION
Field rate up-conversion with line icker reduction
The line flicker reduction in conjunction with field rate
up-conversion is performed by generating a 50 Hz
interlace on the 100 Hz field rate display. Median filtering
supplies the data for the interlaced output fields.
DEFINITIONS
Framel: l is the number of an input/output frame
temporarily combinating an A and B field.
: x is the field raster where A means an odd field and
B means an even field.
Framel, k: l is the number of an output frame temporarily
combinating an origin/interpolated A and B field;
k indicates the origin input field with
k = 1: odd input field and raster A
k = 2: even input field and raster B within framel.
: n, m = lines of fieldn, m are interpolated by
2 lines of fieldn and 1 line of fieldm using the median filter
(see Fig.3); x is the field raster where A means an odd field
and B means an even field.
