Low delay mode
The low delay mode is a function to reduce the amount
of delay between the image sensor output and the
image output.
During the low delay mode, the following functions
cannot be used due to the HW constraint.
• Digital zoom
• Distortion correction
During the low delay mode, the angle of view is shifted
to the Tele side in the 720 output mode due to the HW
constraint.
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.
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/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.)
