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, input the same sync signal to all cameras.

For connections, see “Connecting Two or More Cameras – Multi Camera System” on page 51.

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 menu. Select H. PHASE from the SYSTEM menu.

For more details, see “Operation through Menu” on page 14.

3 Adjust the subcarrier phase using the menu. Select SC. PHASE from the SYSTEM menu. First adjust the subcarrier phase roughly with SC. PHASE ROUGH by setting to between 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.

Chapter

1 Adjust the horizontal phase. Select H. PHASE from the

SYSTEM menu, and adjust so that the reference video

2

 

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 by setting to between 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.
