Preliminary Data Sheet
For STOPMODE=0011 (Micronas soft mix I) the high performance motion detector is used to switch
motion adaptive pixel by pixel between different algorithms. This scan rate conversion method
results in a high performance line flicker reduction (see also
Principles of scan rate conversion
on
page 55).
The table below shows all possible display raster sequences for the different static operation modes
and the lines per field value between two consecutive output V-Syncs. It is assumed, that in case of
freerunning-mode LPFOP=156 and in the locked mode the number of lines of the incoming field is
312.5.
Display raster sequence for RMODE=1 (progressive)
Display raster sequence for RMODE=0 (interlaced)
All static operation modes can be influenced by the I2C bus parameters FIXSHR, MEDON,
CSMOFF and PSMOFF. Some fields are raster interpolated. Two raster interpolation methods are
implemented, which can be switched using the I2C parameter MEDON.
