Adjusting the Picture Tone in a Multi-Camera System

When configuring a multi-camera system, adjust all cameras
to prevent camera-to-camera variations in picture tone.
Before making the adjustments outlined below, supply the
same sync signal to all cameras.
For more details, see "Connections for a Multi-Camera
System" on page 77.
Connecting the cameras to video equipment
with phase indication capability
When connecting to a special-effects generator, a chroma-
key unit, or other video equipment with phase indication
capability, the basic adjustment procedure is as follows:
1
Turn on the phase indication capability of the
connected video equipment.
2
Adjust the horizontal phase using the "H.Phase"
function on the "3. General Setup" menu (page 3).
For more details, see page 95.
3
Adjust the subcarrier phase using the "H.Phase" function on
the "3. General Setup" menu (page 3). First set to between
0° and 180° for rough adjustment, then use "(SC)fine".
For more details, see page 95.
For more details, refer to the instruction manual of the
connected video equipment with phase indication capability.

Connecting the cameras to video equipment
without phase indication capability
Use one of the cameras as a reference camera and adjust the
other cameras to the reference camera one by one.
1
Adjust the horizontal phase. Using the "H. Phase"
function on the "3. General Setup" menu (page 3),
adjust so the reference video signal and the output signal
have the same horizontal sync phase. Use a waveform
monitor or an oscilloscope to check the phase.
2
Adjust the SC phase. First set to between 0° and 180°
for rough adjustment, then use "(SC)fine" for fine
adjustment so that the reference video signal and the
output video signal have the same subcarrier phase.
Use a vectorscope or the wiping function of a special-
effects generator so that the images of both the
reference camera and the camera to be adjusted appear
next to each other on the screen.
