Adjustments
Manual adjustment
Manual adjustment can be performed only in the user
mode.
1
Select “AWC A” or “AWC B” for the white balance.
2
Shoot a white subject to fill the screen, and attain the
automatic white balance.
3
Vary the R (red) and B (blue) gain using Painting on
the color set sub-menu, and adjust it so that the
carrier in the white area of the video signals is
minimized (or so that the white area of the image
turns white). (Perform this adjustment using an
oscilloscope or waveform monitor.)
When performing the adjustment using the
camera
After having attained the automatic white balance, adjust the R (red) and B (blue) gain
using the R and B gain controls of the RCU (RCB).
<Notes>
O
The white balance may not be attained properly if the subject brightness is insufficient.
O
After setting the white balance, the level is stored for a prolonged period in the
memory inside the camera even when the camera’s power is turned off. There is no
need to set it again provided that the status of the subject’s color temperature remains
unchanged. However, if the setting conditions change (if the shooting location
changes from outdoors to indoors or vice versa, for example), set the white balance
again.
O
If the white balance is set when using the camera by itself, the setting for the R (red)
and B (blue) gain adjustment using Painting will return to ±0. (The Painting settings
are valid only in the user mode.)
Automatic color temperature tracking (ATW)
It is a good idea to use the camera in the ATW mode if the lighting conditions at the
shooting site are likely to change (prolonged shooting outdoors, etc.).
When “ATW” is selected as the white balance setting, compensation is provided
automatically so that the white balance is attained automatically even when the light
source or color temperature changes to ensure that the images look natural.
<Note>
The white balance may shift if there is no white on the screen.
3200 K, 5600 K presettings
When “P SET 3200K” or “P SET 5600K” is selected as the white balance setting, the
status is established in which the white balance is set at a color temperature of 3200 K
or 5600 K, respectively.
When performing the adjustment using the RCU (RCB)
Minimize the carrier.
