Setting the CCD scan mode (DSR-450WS/450WSP only)
Since the camcorder has CCDs that use an “all pixels
readout method,” a progressive scan mode is also available
in addition to the conventional interlace scan mode.
You can select either of the following modes using the
FORMAT page of the OPERATION menu.
• I (interlace scan) mode
• PsF (progressive scan) mode
• 24P mode (DSR-450WS only)
Each mode is described below using timing charts.
I (interlace scan) mode
PsF (progressive scan) mode
24P mode
To set the CCD scan mode
The scan mode of the camcorder has been set to I (interlace
scan) mode at the factory. The FORMAT page of the
OPERATION menu allows you to change the CCD scan
mode to PsF (progressive scan) mode or 24P mode.
The video signal of an odd scanning line and that of an even scanning
line are output from the CCD alternately. Thus, the timing of the odd-
field video signal and even field video signal are different.

Video output signal
The video signal of an odd scanning line and that of an even
scanning line are output from the CCD at the same time. Then they
are sent to the memory and separated into odd-field and even-field
scanning lines. Thus the timing of an odd-field video signal and an
even-field video signal are the same.

After reading from the CCDs in 24P mode (23.98 frames per second),
a pull-down conversion is carried out to the 30 frames (29.97 frames
per second) of the normal progressive scan mode.
