NOTE
●
The Auto mode may not be effective if lighting is insufficient and the object
is dark. In this case, increase the camera sensitivity (high limit values of
AGC and slow shutter) or set white balance to the Fixed mode.
●
White balance may not be optimal depending on the type of fluorescent
lamp even when shooting indoors (fluorescent lamp), in which case change
to other setting.
●
White balance may not be optimal in the Auto mode under a sodium vapor
lamp. In this case, set the AWB control range to wide or to the Manual mode
referring to "AWB Control Range."
● WB Manual GAIN - R, WB Manual GAIN - B
Set a gain for a white balance in the Manual mode. Match the white
balance by operating R gain and B gain.
Increase the value to increase the set gain and reduce the value to
reduce the set gain.
● AWB Ye/Cy Offset, AWB Mg/G Offset
Set the white balance offset. In the Auto mode of white balance, offset
the convergent point of white balance in the direction of a preset color,
to obtain a desired color tone.
Ye/Cy Offset:
The convergent point shifts to the yellow side when
the value is increased toward the plus side, shifting
to the cyan side when increased toward the minus
side.
Mg/G Offset:
The convergent point shifts to the magenta side when
the value is increased toward the plus side, shifting
to the green side when increased toward the minus
side.
● AWB Range
Set the control range of white balance in the Auto mode.
Standard: The operating color temperature range is approx. 2500K to
approx. 7000K.
Wide:
The operating color temperature range is approx. 2200K to
approx. 9000K.
NOTE
●
A wide setting may cause an unnatural hue of the image.
● Auto Gain Control
Set a maximum value for operational gain of the auto gain control cir-
cuit. Set to maximum if the object is too dark and camera sensitivity is
low.
The camera sensitivity increases in the order of "OFF," "standard" and
"Max" Noise also increases when Auto Gain Control is near maximum.
Lighting is recommended to obtain good image quality.
NOTE
●
If sensitivity is still short after setting Auto Gain control, set the high limit
value of the slow shutter and auto B/W function, to further increase sensitivity.

● Auto B/W
Configures Auto black and white function. Auto B/W is the func-
tion to gain sensitivity by turning to B/W automatically when it
becomes dark. The image may have some noise in B/W mode.
ON： Auto B/W takes action.
OFF： Auto B/W does not take action.
● White Balance (WB)
White balance adjustment is needed to obtain images of a correct
color tone. The camera offers selection of a white balance mode -
auto white balance (AWB), fixed (indoor and outdoor), hold or manual.
In the Auto mode, the camera automatically accomplishes a white
balance.
The auto operating color temperature range is approx. 2500K to
approx. 7000K when "AWB Range" is set to standard and is approx.
2200K to approx. 9000K when "AWB Range" is set to wide. WB
is automatically achieved in almost all situations, except when
the object is dark or un-white, in which case a good balance some-
times cannot be achieved. In this case, set to the Fixed or Manual
mode.
