Adjusting the Picture Tone on a Multi-camera System
When configuring a multi-camera system, it is necessary
to adjust all cameras to prevent camera-to-camera
variations in picture tone.
Supply the same sync signal to all cameras (see page
2-6(E)), then make adjustments as instructed below.
When Connecting the Cameras to Video

When the cameras are connected to a special effect
generator, a chroma keyer or other video equipment
having a phase indication capability, the basic adjustment
procedure is as follows.
1 Activate the phase indication capability of the
connected video equipment.
2 Adjust the horizontal phase using the H. PHASE
function of the menu (see page 4-10(E)).
3 Adjust the subcarrier phase.
First make a coarse adjustment for 0° or 180° using
the 0/180 item of the menu, then a fine adjustment
using the SC item. (See page 4-11 (E).)
For more details, refer to the instructions manual for the
connected video equipment with phase indication
capability.
When Not Connecting the Cameras to Video
Equipment with Phase Indication Capability
Use one of the cameras as reference camera and adjust
the other cameras to the reference camera one by one.
1 Adjust the horizontal phase.
Using the H. PHASE function of the menu (see page
4-10(E)), make adjustment so that 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 subcarrier phase.
First make a coarse adjustment for 0° or 180° using
the 0/180 item of the menu, then make adjustment
using the SC item so that the reference video signal
and the output video signal have the same subcarrier
phase, (See page 4-11 (E).)
© Use a vectorscope or the wiping capability of a
special effect generator so that the reference camera
picture and the picture from the camera to be
adjusted are both displayed on the monitor screen in
vertical or horizontal juxtaposition.
