Preliminary Data Sheet
Output write parameter: MEDON
In addition a temporal mixing of the different fields can be switched on using the parameters
FIXSHR, CSMOFF, PSMOFF. Temporal mixing may be used for better line flicker reduction
performance.
Output write parameter: CSMOFF, PSMOFF, FIXSHR
The adaptive operation modes (ADOPMODE) define a dynamic switch between different static
operation modes controlled by several internal signals. The start point of all modes is the actual
chosen STOPMODE as described before. The tables below shows the different adaptive operation
modes. The internal used control signals are GMOTION, MOVMO and MOVPH (see also
Global
motion, movie mode and phase detection
on page 33). Furthermore the internal control signal
VTSEQ exists. In case of parameter VCRMODE=1, VTSEQ is still zero. If VCRMODE=0, VTSEQ
can be equal one (see also
Input sync controller (ISC)
on page 11). In this cases the scan rate
conversion is forced to a simple field based scan rate conversion algorithm. All internal control
signals GMOTION, MOVMO and MOVPH are also readable by the I2C-bus interface.
