Gain
An analog gain can be applied, in case of low luminosity for example.
Gain is controlled by XML entry:
•

Supported values are “x1”,
”x2”, “x4””.

Counter Information
An optional counter information can be enabled.
When enabled
(“

”)
, this counter information is integrated in the first pixels of every transferred frame and
replace the first 40 bits. Replaced pixels (up to 5) are
This 40bit counter is built as follow:
•
16 first bits contain an image counter (incrementing with every frame transferred)
•
24 next bits contain a micro-second precision counter that indicates the time when the frame
exposure has started.
When disabled
(“
No
”
), no information is integrated in the transferred frames and all bits are pixel data.
Counter Information is controlled by XML entry:

Remarks:
-
In Mono8/Bayer8 pixel formats, the first 5 pixels (5x8b = 40b) are entirely used as
“Counter
information”. The 6
th
pixel is the first “sensor pixel”.
-
In Mono12/Bayer12 pixel formats, the first 4 pixels (4x12b = 48b) are used. The 40 first bits are used as
“Counter information” and the 8 remaining bits are not used. The 5
th
pixel is the fi
rst “sensor pixel”.
