Panasonic AG-DVC 200E manual White balance and black balance adjustment, 50 Hz, 60 Hz

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 colours change in synchronization with the power line frequency. Particularly in areas where this frequency is 60 Hz, the unit’s vertical sync frequency (50 Hz) and the lighting frequency (60 Hz) will be subject to mutual interference, causing the colour 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.

Automatic white balance adjustment

1 Set the switches to the positions shown in the figure.

1Set the WHITE BAL switch to A or B.

2Set 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.

3 Adjust the lens iris.

4 Push the AUTO W/B BAL switch to AWB and release it.

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

5 A message corresponding to the AWB execution status appears inside the viewfinder.

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

<Notes>

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

≥If the white 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 Centre representative.

<Reference>

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.

Automatic black balance adjustment

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

1 Push the AUTO W/B BAL switch to ABB and release it.

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

ENGLISH

2 Erect a white pattern at a location subject to the same conditions as the light source illuminating the subject, zoom in, and fill the screen with white.

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.

At least one-fourth of the screen width

At least one-fourth of the screen height

<Note>

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

2 A message corresponding to the ABB execution status appears inside the viewfinder.

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

<Notes>

≥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 Centre 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.
