(6) Synchronization (SYNC)
This camera supports the following three sync modes,
which are listed in priority sequence from highest
priority to lowest.
(1) Multiplexed vertical drive (VD2)
(2) Internal sync (INT)
(3) Line-lock (LL)
Input of a multiplexed vertical driver (VD2) signal
automatically switches to VD2 sync, regardless of the
camera's current sync mode (SYNC). In this case, the
camera setting menu shows EXT (VD2) for the SYNC
setting, which cannot be changed to internal sync
(INT) or line-lock (LL).
The following procedures explain how to select internal
sync (INT) and line-lock (LL), and how to perform
phase adjustment when line-lock (LL) is selected.
1. Move the cursor to SYNC, and then tilt the joystick
left or right to select the sync mode.
INT : Internal sync. This is the factory default setting.
LL : Line-lock (Cannot be used in areas with 50 Hz
power.)
Selecting LL and pressing the CAM (SET) button
will display the SYNC setting menu, which can be
used for configuring detailed settings. (This page)
● Adjusting the Phase for Line-lock
Synchronization
Connect the video output signal of the camera being
adjusted and the reference video output signal to a
two-input oscilloscope.
Set the oscilloscope to the vertical rate, and then
expand the vertical sync portion on the oscilloscope.
1. Move the cursor to COARSE, and then tilt the
joystick left or right to align the coarse adjustment
of the vertical phases of the camera being adjusted
with that of the reference camera.
Coarse adjustment be performed across 16 steps
(1 through 16). Adjusting past step 16 returns to
step 1.
2. Move the cursor to FINE, and then tilt the joystick
left or right to align the fine adjustment of the
vertical phases of the camera being adjusted with
that of the reference camera.
Notes:
• To reset COARSE and FINE to the preset values,
press the F3 button. For WV-RM70, press the
right and left switches simultaneously. COARSE
is preset to zero-crossing of the AC line phase.
• If the AC line phase contains spike noise, etc.,
the vertical phase of the video output signal may
be disturbed.
(7) White Balance (WHITE BAL)
1. Move the cursor to WHITE BAL, and then tilt the
joystick left or right to select a white balance mode.
(1) Auto-Tracing White Balance Mode (ATW1/ATW2)
In this mode, the camera continually monitors
the color temperature of the light source and
automatically adjusts white balance.
The following are the approximate supported
color temperature ranges in this mode.
ATW1: 2,700 K to 6,000 K. This is the factory
default setting.
ATW2: 2,000 K to 6,000 K (Mode recommended
for sodium lighting)
Proper white balance may not be possible under
the following conditions. In such cases, use the
AWC while balance mode.
• When the subject contains mostly dark colors
• When the light source is a deep blue sky or
twilight
• When illumination of the subject is low
(2) Auto-Tracing White Balance Control (AWC)
In this mode, the supported color temperature
range is approximately 2,000 K to 10,000 K. This
mode is best in locations where the light source
is constant.
(a) To select AWC, tilt the joystick left and select
AWC →PUSH SET.
(b) Press the CAM (SET) button to start white
balance adjustment. PUSH SET is highlighted
on the display while white balance adjustment is
being performed.
• PUSH SET becomes unhighlighted again when
white balance adjustment is complete. Tilt the
joystick right to display AWC.
• If white balance adjustment cannot be completed
for some reason, PUSH SET will remain
highlighted on the display. If this happens, it could
mean that the color temperature is outside the
supported range, or that illumination is too low.
2. Select ATW1, ATW2, and AWC, then press the CAM
(SET) button, either the ATW setting menu or the
AWC setting menu appears, and you can fine tune
the white balance.
Move the cursor to R or B, and then tilt the joystick left
or right to fine tune the level. The R is red and the B is
blue, moving in the + direction makes the colors
darker, moving in the - direction makes them lighter.
