Panasonic AG-DVC200 Betriebsanweisung

Better  pictures  will  be  produced  by  performing  the  white  balance
and  black  balance  adjustments  in  the  sequence  of  AWB  (white
balance adjustment) 

>

ABB (black balance adjustment) 

>

AWB.

Normally, there is no need to re-adjust the black balance even when
the power is turned on again.

<Notes>
Even  though  the  brightness  under  artificial  lighting  and  especially
under  fluorescent  lights  and  mercury  lamps  may  appear  to  be
constant, the strengths of the red, green and blue colors change in
synchronization with the power line frequency.  Particularly in areas
where  this  frequency  is  50  Hz,  the  unit’s  vertical  sync  frequency
(approx. 60 Hz) and the lighting frequency (50 Hz) will be subject to
mutual  interference,  causing  the  color  phase  to  change  as  time
passes  and  flicker  to  be  generated.    This  makes  it  impossible  to
attain the white balance properly.  It is recommended that the white
balance be attained using the settings shown in the table below.

≥

When  the  gain  selection  value  has  been  changed,  ensure  that
white balance is attained. This will ensure better pictures.

≥

If  the  black  balance  adjustment  was  not  completed  without  an
error,  an  error  message  appears  inside  the  viewfinder.    Try
performing the adjustment again.
If  the  error  message  persists  even  after  another  attempt  at
adjustment,  consult  your  dealer  or  a  Panasonic  Service  Center
representative.

If there is no time to adjust the white balance, set the WHITE BAL
switch  to  PRST.    The  white  balance  will  be  attained  for  the  filter
according to the FILTER control (outer) setting position.
The automatic tracking white balance operation is performed when
ATW has been set ahead of time for the A, B and PRE positions of
the WHITE BAL switch: this comes in handy at such a time.

≥

If  the  black  balance  adjustment  was  not  completed  without  an
error,  an  error  message  appears  inside  the  viewfinder.    Try
performing the adjustment again.
If  the  error  message  persists  even  after  another  attempt  at
adjustment,  consult  your  dealer  or  a  Panasonic  Service  Center
representative.

≥

The gain switching circuit is automatically switched while the black
balance  is  being  adjusted.    Although  flicker  or  noise  may  appear
on the viewfinder screen, this is not indicative of malfunctioning.

1

Set the WHITE BAL switch to A or B.

2

Set the OUTPUT/AUTO KNEE switch to CAM.

3

Normally, set the GAIN selector switch to 0 dB.
If  it  is  too  dark  at  this  setting,  set  the  gain  to  a  more
appropriate level.

4

Set  the  CC/ND  filter  selector  knob  to  the  position
corresponding to the lighting conditions.

Something  white  (a  piece  of  white  fabric  or  a  white  wall)  near
the  subject  can  be  used  instead.    The  required  size  of  the
white object is shown in the figure below.

The  switch  returns  to  the  center,  and  the  white  balance  is
automatically adjusted.

For details, refer to the viewfinder displays (page 16).

Do not allow any high-brightness spots inside the screen.

The black balance must be adjusted in the following cases.

≥

When the unit is to be used for the first time

≥

When  the  unit  is  to  be  used  after  it  has  not  been  used  for  a
prolonged period

≥

When  the  unit  is  to  be  used  where  the  ambient  temperature  has
changed significantly

≥

When the gain selection value has been changed

≥

When the MASTER GAMMA setting has been changed

The switch returns to the center, the iris is automatically set to
the shielded mode, and the adjustment is performed.

For details, refer to the viewfinder displays (page 16).
