Preliminary Data Sheet

Motion detection for scan rate conversion
The motion detection for scan rate conversion results in a motion value for each pixel. The motion
values are stored within the main memory block, read out at the high data rate and used for the
scan rate conversion. The motion detection works on luminance data. In case of VDECON>0 or
HDECON>0 the motion detection for scan rate conversion is disabled. The diagram below shows
the block diagram of the motion detection. Separate line, field and frame differences are calculated.
The result of the differences are fed to separate look up tables. The result FRD of the LUTFR (look
up table frame) depends on the frame difference and the line difference (LDMAX). The result of the
LUTFI (look up table field) FID1 or FID2 depends on the field difference and the line difference.
These three values FRD, FID1 and FID2 determine the motion value mval. The final motion value
“Motion” is generated by the postprocessing block. It is possible to alternate the behaviour of the
motion detection selecting different parameters, which will be described in detail for each block
afterwards.
