Viewfinder screen status displays
In addition to the pictures shot, the unit’s settings and
messages indicating its operating statuses are
displayed on the viewfinder screen.  The center

The items which have been set to ON by the switches
relating to the viewfinder displays or the VF DISPLAY
screen of the setting menu are displayed at the top
and bottom of the screen.
When settings have been changed or adjustments
have been made, messages advising the user of what
has been set, what progress has been made in the
adjustments and what the adjustment results are can
be displayed for about 3 seconds.$Display items and where they are displayed

Adjusting the white balance and black balance
Adjusting the white balance
1Set the switches as shown in the figure.
FILTER controlWHITE BAL: A or B
OUTPUT: CAM
GAIN: Normally 0 dB
Set to a more suitable gain level if it is
too dark.
When the GAIN and WHITE BAL switch settings
are changed, messages advising the user of the
set positions appear on the setting change
message display of the viewfinder screen.
(However, this happens only when “3” has been
set as the display mode.)
2Select the FILTER control setting in accordance
with the lighting conditions.
OFor examples of the FILTER control settings,
refer to the description of the FILTER control
(page 13) in the “Shooting (recording)/playback
function section.” 
When the FILTER control setting is changed, a
message advising the user of the set positions
appears on the setting change message display
of the viewfinder screen.  (However, this
happens only when “3” has been set as the
display mode.) A better picture can be achieved by adjusting the
white balance and black balance in the following
sequence: AWB (white balance adjustment) 
5ABB
(black balance adjustment) 
5AWB.
There is usually no need to re-adjust the black
balance even when the power has been turned off
and back on.
The white balance must always be re-adjusted when
the lighting conditions have changed.
If the display mode is set to “2” or “3,” messages
advising the user of what progress has been made in
the adjustments and what the adjustment results are
appear on the viewfinder screen when the black
balance or white balance adjustment is commenced.
Set the display mode to “1” if these messages are not
to be displayed.
OFor details on the display mode settings, refer to
“Display modes and setting change messages”
(page 43).

OABB must be performed when the MASTER GAIN
levels have been changed on the LOW SETTING,
MID SETTING and HIGH SETTING screens of the
CAM MENU, when the super gain setting has been
changed using the USER button, and when the
GAMMA (ON/OFF) has been switched on the
CAMERA SETTING screen.
OWith artificial lighting—particularly fluorescent lights
and mercury lamps—the luminance may appear to
be constant but the intensity of the R, G and B
colors will change in synchronization with the power
line frequency.  Especially in regions with a 50 Hz
power line frequency, mutual interference arises
between the vertical sync frequency (approx. 60
Hz) of this unit and lighting frequency (50 Hz).  As a
result, the hue tends to change with the passage of
time or flickering occurs, making it impossible to
achieve a proper white balance.
It is recommended that the white balance be
achieved using the settings shown in the table
below.
Power line frequencyShutter speed
50 Hz1/100
60 HzOFF

Adjusting the white balance and black balance
Adjusting the white balance
3Erect a white pattern at a place with the same
conditions as the source of light illuminating the
subject, zoom in, and shoot the white of the pattern
on the screen.
A white object (such as a white cloth or white wall)
near the subject may be used as a substitute for
the white pattern.
The size of the white object required is shown in
the figure below.
4Adjust the lens aperture.
5Set the AUTO W/B BAL switch to AWB, and then
release it.
The switch returns to the center, and the white
balance is automatically adjusted.
At least one-fourth of
the screen width
At least one-fourth of
the screen height

Take care to keep high-brightness spots off the screen.
6While the adjustment is in progress, the following
message appears on the viewfinder screen (but
only when “2” or “3” has been set as the display
mode).
AWB ACTIVE
AUTO W/B BAL switchMessage appearing while the adjustment is in
progress
7Adjustment is completed in several seconds.  (A
message similar to the one shown in the figure
now appears.)
The adjustment value is automatically saved in the
memory (A or B) which was set in step 1.
AWB A OK 3.2K
Message appearing upon completion of the
adjustment 
8A message such as the following appears if the
color temperature of the subject is lower than 2500
K or higher than 5600 K.
The downward pointing arrow indicates that the
color temperature is lower than the display
temperature; conversely, the upward pointing
arrow indicates that the it is higher than the display
temperature.

When a zoom lens with an automatic aperture
function is used, aperture hunting may occur.  Adjust
the aperture’s gain control (marked as IG, IS, S, etc.)
provided with the lens.
For details, refer to the operating instructions which
accompany the lens.
Hunting:
The auto iris response is repeated, causing the brightness levels
of the image to become inconsistant.
AWB A OK 2.5K 
m
When the color temperature is lower than 2500 K
AWB A OK 5.6K 
m
When the color temperature is higher than 5600 K

When the AUTO W/B BAL switch is pressed again to
the AWB side when the white balance is being
adjusted automatically (AWB ACTIVE), the
adjustment operation will stop.
The adjusted value in this case is the value before
automatic adjustment was performed. 
						

							49
Adjusting the white balance and black balance
Adjusting the white balance
When the white balance cannot
automatically be adjusted
An error message appears on the viewfinder screen
(when “2” or “3” has been set as the display mode).
When there is no time to adjust the white
balance
Set the WHITE BAL switch to PRST.  The white
balance for the filter is achieved in accordance with
the setting position of the FILTER control (outer).
White balance memories
There are two sets of white balance memories, A and
B.  
When the FILTER INH setting on the CAMERA SW
MODE screen of CAM MENU is ON (default setting),
the number of memories for set A and set B is limited
to one each.  In this case, the memory contents are
not coupled with the filter.
When FILTER INH is set to OFF, the adjustment
values for each filter can be automatically saved in the
memories corresponding to the WHITE BAL switch
settings (A or B).  This unit contains four filters so that
a total of 8 (4a
2) adjustment values are saved.
When any of the error messages listed above is
displayed, take the recommended action, and try
adjusting the white balance again.
If the error message persists even after repeated
attempts, consult your dealer.

On rare occasions, AWB cannot be adjusted and a
NG display appears.  In a case like this, adjust AWB
again.
