Basic Functions

White Balance

White Balance has the following modes, all of which
can be set using VISCA Commands.

• Auto White Balance

This mode computes the white balance value output
using color information from the entire screen. It
outputs the proper value using the color temperature
radiating from a black subject based on a range of
values from 3000 to 7500K.
This mode is the factory setting.

• ATW

Auto Tracing White balance (2000 to 10000K)

• Indoor

3200K Base Mode

• Outdoor

5800K Base Mode

• One Push WB

The One Push White Balance mode is a fixed white
balance mode that may be automatically readjusted
only at the request of the user (One Push Trigger),
assuming that a white subject, in correct lighting
conditions, and occupying more than 1/2 of the
image, is submitted to the camera.
One Push White Balance data is lost when the power
is turned off. If the power is turned off, reset One
Push White Balance.

• Manual WB

The gain limit can be set in the AE mode. Use this
setting when image signal-to-noise ratio is
particularly important.

• Shutter Priority

Variable Shutter Speed, Auto Iris and Gain
(1/1 to 1/10,000 sec., 16 high-speed shutter speeds
plus 6 low-speed shutter speeds)

1) Flicker can be eliminated by setting shutter to

t1/100s for NTSC models used in countries with a 50 Hz

AE – Shutter priority

The shutter speed can be set freely by the user to a
total of 22 steps – 16 high speeds and 6 low speeds.
When the slow shutter is set, the speed can be

s. The picture output is read at a

normal rate from the memory. The memory is updated
at a low rate from the CCD. AF capability is low.
In high speed mode, the shutter speed can be set up to
1/10,000s. The iris and gain are set automatically,
according to the brightness of the subject.
