Multi-Line Gain
(
MultiLineGain
) :
Enables the MultiLine Gain of x0,5 . This value is available in the
CommCam “Image Format Control” section :
Read function : “
r mlig
”;
Return by the sensor : “0” if disabled (Gain x1 by default); “1” if Gain x0,5 activated.
Write Function : “
w mlig
<value>”
“0” : Default Gain x1 is active.
“1” :
Gain x0,5 is enabled (only when the 2S mode of the sensor is enabled)
Why Using a Multi-Line Gain of x0,5 ?
When the Light source is enough to use the “1S” mode of the Sensor (one single line), the
best is to use 2 lines (“2S” mode) and then to divide the result by two by using the Multi-
Line Gain set at “x0,5” :
In this case, the Full Well capacity is multiplied by x2 (two output registers are used) but the
noise divided by √2 therefore the SNR is improved by a factor of √2.
Reverse Reading (X)
(
ReverseReading
) :
Allows to output the line in the Reverse-X direction. This value is
available in the CommCam “Image Format Control” section :
Read function : “
r revr
”;
Return by the Camera : 0 or 1 (enabled/disabled)
Write function : “
w revr
<value>”;
“0” : Disabled.
“1” :
Enables the reverse reading out (see below for “normal” direction)
Scan Direction
(
ScanDirection
) :
Set the scan direction for the sensor. This value is available in the
CommCam “Image Format Control” section :
Read function : “
r scdi
”;
Return by the Camera : 0, 1 or 2 (Forward/reverse/external)
Write function : “
w scdi
<value>”;
“0” : Forward.
“1” :
Reverse
“2” : Externally controlled (by CC3 of the
CameraLink Sync signals)
