or includes extremely light portions.
Images with wide dynamic range are produced by
combining long-exposure signals (normal shutter) with
the signals of the high-intensity portions obtained with
a short exposure (high-speed shutter).
• About WD Set Parameter
(Command: 8x 01 04 2D 00 0q 0r 0s 00 00 00 00 FF)
q: Display brightness
(0: Dark to 6: Bright)
The brightness and the darkness can be
adjusted to seven levels. The normal brightness
is set to 3.
Initial setting: 3
r: Brightness compensation selection
(0: Darker, 1: Dark, 2: Standard, 3: Bright)
Set the area which you want to adjust the
brightness of the image with WD effect.
Initial setting: 2
S: Compensation level
(0: Low, 1: Mid, 2: High)
The compensation of the brightness, which you
select from the parameter, can be set to three
levels.
Initial setting: 1
Notes
• When the WD is On, false colors may appear in some parts of the
image. This phenomenon is unique to WD, and is not an
indication of a camera malfunction.
• When switching WD mode, images are shown at a maximum of 8
frames at the same time.
Visibility Enhancer (VE)
Depending on the imaging scene, the Visibility
Enhancer function makes the darker part of a camera
image brighter, and automatically correct brightness
and contrast to show bright parts clearly.
Note
This function is also used in the WD operation.
Defog mode
When the surrounding area of the subject is foggy and
low contrast, the defog mode will make the subject
appear clearer.
You can select this function from the four levels: OFF,
Low, Middle and High.
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.
The functions of both 2D NR (removal of 2-
dimentional noise) and 3D NR (removal of 3-
dimentional noise) are provided. When the 2D NR
level is increased, the details of image may be lost
because the smoothing of image with the peripheral
area is performed. Also, when the 3D NR level is
increased, adverse effects such as image blur and
blending in the successive images occur in the moving
portion. In this function, the mode to set the level of
effect by combining 2D/3D (normal setting) and the
mode to individually set the level of effect respectively
(independent setting) are available.
• In the normal setting, you can select the noise
reduction level from 6 levels: levels 1 to 5, plus off.
In this setting, the users cannot adjust the ratio of
2D/3D effect level.
• In the independent setting, you can individually select
the 2D NR and 3D NR from 6 levels respectively:
levels 1 to 5, plus off.
* The 2D/3D NR independent setting is supported in
version 6.00 or later.
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.
