HLC
HLC (highlight correction) is a function to adjust AE
and AF, and to perform the masking of light area as
required when a high intensity spot light is detected.
It allows you to easily read the number of vehicles and
number plate in the indoor parking area or in the
outdoor during the night.
MinimumShutter
When the subject becomes dark, the shutter speed
becomes slow, and then the gain is increased. This is a
function to put a limit on the shutter speed.
It prevents the camera shake when you shoot a moving
subject in a dark place.
Noise Reduction (NR)
The NR function removes noise (both random and
non-random) to provide clearer images.
This function has six steps: levels 1 to 5, plus off.
The NR effect is applied in levels based on the gain,
and this setting value determines the limit of the effect.
In bright conditions, changing the NR level will not
have an effect.
High Sensitivity Mode
In this mode, the maximum gain increases, enabling to
obtain a brighter output even in a darker environment.
However, if the gain reaches high level (up to 4x), the
image will have a large amount of noise.
Variable Gamma Mode
There are standard (01h) mode and straight gamma
(02h) mode.
Gamma Offset
You can set the brightness from -16 (00h) to +64 (40h)
in each mode of variable gamma mode.
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 smoothly zooming up to
approximately 24× using a combination of the optical
zoom and digital zoom. The digital zoom can be
further used to zoom up to 240×. At the wide end, you
can obtain images without any reduction in the
resolution because the digital zoom is not switched On.
The "StableZoom" function can be switched On/Off in
the register settings.
