Settings That Can Be Changed (List of Menu Items)
The following are the descriptions of the menu items and
their settings.
GAIN (video gain)
AGC: for automatical control of video gain.
The gain of the video signal circuitry is automatically
controlled depending on the brightness of the subject.
This function is useful when the illuminance of the
subject varies more or less dramatically.
STEP: for setting the video gain to the desired level.
Use this function for shooting in so dark places that
fully opening the lens iris can still not give an
acceptably bright image. The gain level can be set in
the range of 0 to 18 dB in units of 1 dB.
C.TEMP (color temperature)
3200K: for indoor shooting.
5600K: for outdoor shooting.
WHT.BAL (white balance)
AUTO: for automatical adjustment of white balance
described on page 3-5(E).
MANU: for manual adjustment of white balance. Both
red gain (R.GAIN) and blue gain (B: GAIN) are
adjustable,

CCD IRIS
ON: When an excessive amount of light passes through
the lens, this function increases the shutter speed
automatically to nearly the same effect that the lens
iris is narrowed 3 stops down.
In microscope shootings using a microscope adaptor
without incident light control capability, for example,
an amount of incident light which is not too much for
a human eye will often be so for a video camera. With
CCD IRIS set to ON, an excessive amount of incident
light is automatically decreased to an appropriate level
for the video camera. In another example, if there is a
very bright object (such as snow, or sea water reflecting
sunlight) within the range of view of the lens, the
incident light is automatically decreased to a certain
level if of course the lens has an automatical iris
control capability. Also in such case, CCD IRIS is
useful to give a further decrease of incident light.
OFF: for shooting in normal lighting condition. Also use
this setting when:
© The picture flickers on the monitor screen. This may
occur when using the DXC-930 with lighting power of
$0 Hzor the DXC-930P, of 60 Hz. In such case, set CCD
IRIS to OFF and shutter speed to FL. (See the next
page.)
© The camera is used under fluorescent light. This may
cause slow variations in color to the picture. If the
degree of color variations is unacceptable, set CCD
IRIS to OFF.
