Basic Functions
Note
Flickering in images during color enhancement is not an indication
of a camera malfunction. It can be reduced with the threshold level,
hysteresis width, and edge enhancement (aperture) settings.
Image Stabilizer
Switching ON the Image Stabilizer function reduces
image blurring caused by, for example, vibration,
which allows you to obtain images without much
blurring. A correction effect of approximately 90% 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.
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.
Slow shutter – Auto/Manual
When set to “Auto,” ensures that the slow shutter is set
automatically when the brightness drops. Effective
only when the AE mode is set to “Full Auto.”
Set to “Slow Shutter Manual” at shipment.
Note
The Slow Shutter Auto function is not available in WD mode.
ICR (IR Cut-Removable) Mode
An infrared (IR) Cut-Filter can be disengaged from the
image path for increased sensitivity in low light
environments. The ICR will automatically engage
depending on the ambient light, allowing the camera to
be effective in day/night environments.
When the auto ICR mode is set to ON, the image
becomes black and white.
Auto ICR Mode
Auto ICR Mode automatically switches the settings
needed for attaching or removing the IR Cut Filter.
With a set level of darkness, the IR Cut Filter is
automatically disabled (ICR ON), and the infrared
sensitivity is increased. With a set level of brightness,
the IR Cut Filter is automatically enabled (ICR OFF).
Also, on systems equipped with an IR light, the
internal data of the camera is used to make the proper
decisions to avoid malfunctions.
Auto ICR Mode operates with the AE Full Auto
setting.

When in Auto_ICR_OFF state and WB data is added (default), a
malfunction may occur when the subjects largely consisting of blue
and green colors are taken.
