then use the UP or DOWN buttons to adjust the
speed.
OFF : This mode corresponds to the standard 1/60
(NTSC), 1/50 (PAL).
Reference [Dispiay shutter speed] on page 17.
@ WHENTO USE
A shutter speed of 1/60th (NTSC), 1/50th (PAL) second is too
slow to prevent blurring from normal actions when as subject is
moving.
This gives a smooth and natural effect when watching motion
normally, but in certain applications the video is to be displayed
in slow motion or as a freeze. The blurring in this case reduces
the possible sharpness of the image.
As one increases the shutter speed the amount of light col-
lected is less and less, so consideration should be given to the
effects of openning the iris and increasing gain.
Opening the iris reduces depth of field and causes foreground
and background objects to go out of focus. This is a useful
artistic technique.

6690 8
The DNR allows improvement of the S/N. However, as this
increases residual images in the case of moving subjects,
the DNR should be turned on/off while observing the out-
put video.
ON _ _: The DNR is activated.
The setting values can be changed as described
in “DNR LEVEL” on page 44.
AUTO : The DNR varies automatically according to the cur-
rent gain.
OFF: The DNR is deactivated.
CAUTION :
if the sensitivity is increased (e.g., to 9dB or 18dB) un-
der fluorescent lighting and the DNR is used at ON, these
may be electrical noise caused by the flickering.
