Adjustments and Settings for Shooting
5
Move the cursor to one of the items you wish to adjust/
set, mentioned below, using the +/
−
switch on the DTX
board. Then push the CANCEL/ENTER switch to the
ENTER position once.
REDUCER
Set the flicker-reduction function on/off.
ON:
The flicker-reduction function is activated.
OFF:
The flicker-reduction function is inactivated.
FREQUENCY
Set the power supply frequency, according to that of
your area.
50Hz:
In an area where the power supply frequency is
50 Hz
60Hz:
In an area where the power supply frequency is
60 Hz
GAIN
Use to adjust the correction amount that the system
automatically calculated.
Depending on the brightness level and the colors of
images on the screen, the correction amount calculated
by the system may be different from the optimum
value for the region to be corrected. In such a case,
adjust the GAIN value to make the correction amount
closer to the optimum value.
-99:
Small correction amount (equivalent to OFF)
99:
Greater correction amount
OFFSET
Adjust the video level from which correction will be
applied.
Generally, fluctuation range of flicker is greater in a
bright region and smaller in a dark region. Depending
on the distribution of the brightness levels of an image
on the screen, set the brightness level of the video
signal for which correction is to be applied where that
level is exceeded.
0:
Black level
99:
White level
ADV MODE
Set the response time for fluctuations of flicker noise.
The system responds to fluctuations of flicker noise on
the screen with 2 different response times.
DISABLE:
Approx. 0.05 sec
ENABLE:
Approx. 1 sec
With the rapid response time, correction can respond
to a rapid change in fluctuations. However, excess
correction amount may result when there is instant
change (e.g.: another subject is cutting across the
scene).
On the contrary, with the slow response time,
correction amount in response to an instant change
becomes smaller, but it will take longer for an excess
correction to be normalized.
AREA SELECT
Select a split pattern for flicker reduction.
Correction will be performed independently in each
split area. More effective flicker reduction can be
achieved by selecting a suitable pattern, according to
flicker noise patterns on the screen.
For uniform flicker noise on the entire screen, select
CENTER.
H&V:
Four blocks, formed by vertically and
horizontally dividing the screen
V:
Divided into four full-width blocks
CENTER:
Entire screen

After all necessary settings are completed, set the
menu control switch on the DTX board to OFF to
terminate Menu mode.
