Setting the CCD scan mode (DSR-450WS/450WSP only)

Since the camcorder has CCDs that use an “all pixels

• I (interlace scan) mode

readout method,” a progressive scan mode is also available

• PsF (progressive scan) mode

in addition to the conventional interlace scan mode.

• 24P mode (DSR-450WS only)

You can select either of the following modes using the

 

FORMAT page of the OPERATION menu.

Each mode is described below using timing charts.

I (interlace scan) mode

 

CCD output

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

O: Odd E: Even

PsF (progressive scan) mode

CCD output

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

Video output signal

even-field video signal are the same.

1/29.97 seconds

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

 

 

O: Odd E: Even

 

per second) of the normal progressive scan 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.
