When configuring a multi-camera system,
adjust all cameras to prevent camera-to-
camera variations in picture tone.
Before making the adjustments outlined
below, input the same sync signal to all
cameras.
For connections, see “Connecting Two or
More Cameras — Multi-Camera System” on
page 31.
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
Select H. PHASE from the SYSTEM
menu, and adjust the horizontal phase.
For more details, see “SYSTEM Menu”
on page 20.
3
Select SC. PHASE from the SYSTEM
menu, and adjust the subcarrier phase.
First adjust the subcarrier phase roughly
with SC. PHASE ROUGH set to 0° and
180°, then adjust it finely using SC.
PHASE FINE.
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. Select
H. PHASE from the SYSTEM menu,
and adjust 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. Select
SC. PHASE from the SYSTEM menu.
First adjust the subcarrier phase roughly
with SC. PHASE ROUGH set to 0° and
180°, then adjust it finely using SC.
PHASE FINE 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 to display the
images of both the reference camera and
the camera to be adjusted
simultaneously on the screen.
