Panasonic WV-CF254 manual White Balance Setting White BAL, Line-lock Sync Mode LL

5-1. Line-lock Sync Mode (LL)

1.Move the cursor to the SYNC parameter and select LL.

Note: The settings in this menu can be made only when the multiplexed vertical drive signal (VD2) is not supplied to the camera.

2.After confirming the cursor is on LL, press

(S). The vertical phase adjustment menu appears on the monitor.

3.Move the cursor to COARSE. The cursor starts blinking.

4.Supply the video output signal of the camera to be adjusted and the reference camera video output signal to a dual-trace oscilloscope.

5.Set the oscilloscope to the vertical rate and expand the vertical sync portion on the oscillo- scope.

6.Press (L) or (R) to match the vertical phase for both video output signals as closely as possible. (COARSE adjustment can be incre- mented in 16 steps by 22.5 degrees by press-

ing (L) or (R).)

1 (1 - - 16): 0 degrees

2 (1 - - 16): 22.5 degrees

16 (1 - - 16): 337.5 degrees

Note: After the sixteenth step, the adjustment returns to the first step.

7.Move the cursor to FINE. The cursor starts blinking.

8.Press (L) or (R) to match the vertical phase for both video output signals as closely as possible.

(FINE adjustment can be made up to 22.5

degrees by pressing (L) or (R).)

Notes:

•When the “I” cursor reaches the “+” end, it jumps back to “−”. At the same time, COARSE is incremented by one step to enable a continuous adjustment. The

reverse takes place when the “I” cursor reaches the “−” end.

•When (L) or (R) is kept pressed for a second or longer, the “I” cursor moves faster.

•To reset COARSE and FINE to the values

preset at the factory, press (L) or

(R)simultaneously. COARSE and FINE adjustments are preset at the factory to zero-crossing of the AC line phase.

•If the AC line contains noise (spike noise, etc.), the stability of the vertical phase of the camera video output signal may be disturbed.

6.White Balance Setting (WHITE BAL)

You can select one of two modes for white balance adjustment as follows:

• ATW (Auto Tracing White Balance)

In this mode, the color temperature is monitored continuously and thereby white balance is set automatically. The color temperature range for the proper white balance is approximately 2 600 - 6 000K. Proper white balance may not be obtained under the following conditions:

1.The color temperature is out of the 2 600 - 6 000K range.

2.When the scene contains mostly high color temperature objects, such as a blue sky or sunset.

3.When the scene is dim.

In these cases, select the AWC mode.

Move the cursor to the WHITE BAL parameter and select ATW. The white balance of the camera is automatically set.
