7.2 CAMERA PARAMETER CHANGE
Selecting the
“Camera”
option and pressing
SET
, the user accesses some DataVS2
parameters such as:
exposure time, gain and illuminator operating mode
.
The user can change the focus between the objects on the panel by using the
UP/DOWN
ARROWS
. To change the parameter value, once selected the focus, the user has to use the
RIGHT/LEFT ARROWS
.
Parameter
Description
Change
Exposure time
The exposure time identifies the period that
the lens remains open and allows light to
reach the CMOS mounted on the sensor.
Therefore, the longer the exposure time,
the brighter the image will be. On the other
hand, increasing the exposure times
increases the risk of acquiring blurred
images where the detail being monitored
moves at a certain speed. If the images of
objects that move quickly are not very
bright, it is recommended to adjust the gain
settings.
To adjust the exposure
time, move to the option
and use the
RIGHT/LEFT
ARROW
buttons.
Press
STATUS
to change
the scale of the slider
values.
(At each pressing the scale
is increased of one order
of magnitude).
Gain
The gain setting allows you to adjust the
brightness of the image acquired by the
sensor by amplifying the signal transmitted
by the CMOS to the processing unit.
Increasing the gain setting, however, also
increases the disturbance on the image
which decreases its quality.
To adjust the gain setting,
move to the option and use
the
RIGHT/LEFT ARROW
buttons.
Illuminator
This parameter is referred to the illuminator
inside the sensor and only one of the three
options can be selected: OFF, ON and
POWER.
To adjust the gain setting,
move to the option and use
the
RIGHT/LEFT ARROW
buttons.
Once the camera settings have been completed, it is possible to return to the Setup menu by
pressing
ESC
.
