Camera/Basic Settings (Cont.)

●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.

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.
