Detection area for the white balance
The detection area for the white balance is selectable between
90%, 50% and 25%, using the menu option AWB AREA.
This option can be found in the <WHITE BALANCE MODE>
screen, which is accessible from the CAM OPERATION page.
The detection area is factory-set to 25%.
When you have no time to adjust the white balance:
Position the WHITE BAL switch at [PRST].
This adjusts the white balance for the filter according to the
position of the FILTER control (outer).
When the white balance has not been automatically
adjusted:
When the white balance has not been successfully adjusted, the
viewfinder displays an error message.
If one of the error messages listed below appears, take the
appropriate steps, then adjust the white balance again.
If the error message appears after repeated readjustments, the
interior of the unit must be inspected. For more information,
contact a service center or your distributor.
Retaining white balances
Each value in memory is retained even if the video camera-
recorder is turned off; it will not be lost until the white balance is
re-adjusted. White balances are stored in either of two systems:
A or B.
When the menu option FILTER INH is set to “ON” (default), each
system stores only one value. If this is the case, the values are
not synchronised with the CC filter.
This option can be found in the <WHITE BALANCE MODE>
screen, which is accessible from the CAM OPERATION page.
When the menu option FILTER INH is set to “OFF”, the adjusted
value for each CC filter can be automatically stored in the
memory that corresponds to the position of the WHITE BAL
switch (A or B). Your AJ-SPX900E has four built-in CC filters; it
stores eight (4 C 2) adjusted values.
Note that, when the menu options AWB A and AWB B are set to
“VAR”, the color temperatures specified through COLOR TEMP
A and COLOR TEMP B are used, meaning that the white
balances cannot be adjusted with the AWB switch. The menu
options are found in the <WHITE BALANCE MODE> screen,
which is accessible from the CAM OPERATION page.
Setting the auto-tracking white balance (ATW)
The AJ-SPX900E has an auto-tracking white balance (ATW)
feature that automatically tracks the white balance for pictures
according to lighting conditions.
The ATW feature can be assigned to Position [B] of the WHITE
BAL switch. To do so, the menu option AWB B must be set to
“ATW”. This option can be found in the <WHITE BALANCE
MODE CAM> screen, which is accessible from the CAM
OPERATION page.
The ATW feature may be assigned to the USER MAIN, USER1,
or USER2 button. For more information, see [4-9-4 Assigning
Functions to USER MAIN, USER1 and USER2 Buttons].
To cancel the auto-tracking white balance:
Press the user button that has the ATW feature assigned, or
change the position of the WHITE BAL switch. Note that, when
the ATW feature is assigned to [B] of the WHITE BAL switch, the
auto-tracking white balance cannot be canceled with a user
button.
<Note>
This function does not guarantee 100% accuracy of the white
balance.
When using the AJ-SPX900E, remember that there will be some
allowance in the trackability of changes in lighting conditions and
pull-in accuracy of white balances.
