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.

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.

O: Odd  E: Even

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.
