Step 2
Set ISP parameters. For detailed parameter description, see
Table 6-4
ISP Parameter description
Parameter
Description
Day/Night mode
The day/night mode helps the IPC to adapt to low
illumination conditions. The options are as follows:
l
Auto (default): The IPC automatically switches between
day and night modes based on illumination conditions.
l
Color: The IPC captures color images.
l
B/W: The IPC captures black and white images.
Day/Night sensitivity
This parameter is available only when you set
Day/Night
mode
to
Auto
.
The day/night sensitivity refers to sensitivity for switching
between color mode and B/W mode. A higher sensitivity
indicates higher flexibility to switch from B/W mode to
color mode. The default value is
High
.
Gain limit
This parameter is available when you set
Day/Night mode
to Color or
B/W
.
The gain limit function is used to restrict the upper limit of
the Automatic Gain Control (AGC).
l
In the case of low illumination conditions, the AGC can
be enhanced to improve image brightness. However, a
high level of AGC will increase the image noise and
degrade the image quality. Set this parameter based on
the site requirements.
l
When
Metering mode
is set to
Average metering
in
infrared light conditions, over-exposure will occur on
the area with light in the foreground. By setting this
parameter, this phenomenon can be eased.
Exposure compensation
coefficient
Exposure compensation is a technique for adjusting the
exposure indicated by a photographic exposure meter, in
consideration of factors that may cause the indicated
exposure to result in a less-than-optimal image.
Auto aperture
l
If you select the check box, the aperture is automatically
adjusted. The default value is selected.
l
If you deselect the check box, the fixed aperture is the
maximum aperture.
NOTE
When the auto aperture function is enabled but the aperture cannot
be fixed (resulting in flashing video image), you can disable the
auto aperture function.
