Gamma Offset
You can set the brightness from -16 (00h) to +64 (40h)
in each mode of variable gamma mode.
Contrast Adjustment Function (supported in
version 6.00 or later)
You can adjust the contrast level in the range from 0
(00h) to 255 (FFh). The initial setting is 128 (80h). The
smaller the value is, the lower the contrast becomes,
and the larger the value is, the higher the contrast
becomes.
Note
This function is available when the variable gamma mode is
set to standard (00h) mode and when VE/WDR/HLC are set
to OFF.
Color Enhancement
A color image can be created two colors brighter and
darker than the threshold value.
(The threshold level can be set with an optional level.)

Note
Flicker on images with color enhancement is not a malfunction of
the camera. Flicker can be reduced by setting the threshold level
and the aperture control.
Temperature Reading Function
The conversion value (hex) of the temperature sensor
built into to the camera can be read by using a query
command. The conversion value has an error of ±3 C,
and because the temperature sensor is inside the
camera, this value is not the ambient temperature. Use
it as a reference value.
"StableZoom"
"StableZoom" is a function for performing correction
using the Image Stabilizer function in accordance with
the zoom ratio, and smoothly zooming up to
approximately 36× using a combination of the optical
zoom and digital zoom. The digital zoom can be
further used to zoom up to 360×. At the wide end, you
can obtain images without any reduction in the
resolution because the digital zoom is not switched On.
On the other hand, at the tele end, the correction effect
by the Image Stabilizer function is at its maximum so
blurring is reduced. The "StableZoom" function can be
switched On/Off in the register settings.

Image Stabilizer
Switching On the Image Stabilizer function reduces
Assign any
image blurring caused by, for example, vibration, which
color
allows you to obtain images without much blurring. A
correction effect is possible for a vibration frequency of
around 10 Hz. The Image Stabilizer function employs
the digital zoom system, so the angle of view and
resolution are changed, but the sensitivity is
maintained.
Hold Function of Image Stabilizer
With the Image Stabilizer function, suddenly stopping
high-speed movement (pan, tilt, etc.) of the camera
produces a blur sensor counteraction that may cause
image movement. In such a case, you can use a
command setting (hold) to maintain the correction of
the Image Stabilizer function. In this case the image
stabilizer is off, but there is no change in the angle of
view.
Note
The hand shake correction function may not work correctly under
the condition that high-frequency vibration component exits. In
such a case, set the image stabilizer function to Off.
