Place a white pattern in the same lighting conditions
as the subject, and zoom in on it so that a white area
is obtained in the screen to satisfy the positional and
quantitative requirements illustrated below.
A white object (white cloth, a white wall, etc.) near the
subject may be used in place of a white pattern.
Be careful not to have any spots of high illumination in the
rectangle.

Adjust the lens iris opening.
With a manually adjusted lens:
Set the iris to an
appropriate value.
With a lens which has automatic iris control:
Set the
lens’ automatic/manual iris control switch to
automatic.
5
Execute auto white balance (AWB) from the MSU or
RCP.
White balance automatic adjustment begins.
During adjustment, the message “AWB : EXECUTING”
will be displayed on the viewfinder screen.
A message like the one in the figure below will be
displayed, and the adjustment process will complete. The
adjusted value is automatically stored.
When using a zoom lens with automatic iris control capability,
hunting
1)
may occur. Adjust the lens’ iris gain control (labeled
IG, IS, S, etc.).
1)
Hunting: The automatic iris responds over and over, and the image
repeatedly darkens and lightens.
For more information, refer to the lens’ operation manual.
When automatic white balance adjustment fails
If the white balance adjustment process does not end
successfully, the error message “AWB : NG” will be displayed
on the viewfinder screen for approximately three seconds.
If this error message is displayed, try white balance
adjustment again.
If the error message continues to be displayed after several
attempts, the camera requires internal inspection.
Setting the Electronic Shutter
This section explains the different modes which can be used
for the electronic shutter and gives the procedures for setting
the shutter mode and shutter speed.
About the shutter modes
The shutter modes that can be used with the electronic shutter
of the camera and the shutter speeds that may be selected are
as follows:
* The values in the table are those for 59.94P. With other formats, the
available values are different.
Selecting the shutter mode and speed
Change the shutter speed (SHUTTER) from the MSU or RCP.
The current shutter setting will be displayed on the viewfinder
screen for about three seconds.
Example: “SHUTTER: 1/250”
Example: When 59.94P is selected
Setting the Focus Assist Functions
Using the OPERATION menu, the assist functions for easier
focusing on the viewfinder, can be activated.
Adding the VF detail signal
Adding the VF detail signal to sharp edges in the image on the
viewfinder screen makes it easier to check the focusing
condition by observing changes in the detail signal or in the
color converted from the detail signal (color detail).
