Sensor Mode
(
SensorMode
) : Defines the number of Line used on the Sensor. This command is available in
the CommCam “Image Format Control” section :
Read function : “
r smod
”;
Returned by the camera : Integer from 0 to 5
Write function : “
w smod
” <value> :
“0” : “1S” mode or Single Line.
“1” : “2S” mode or Dual Lines.
“2” : “4S” mode or Four Lines.
“3” : “1SB” mode : Binning mode (2x2) which outputs on line of 4k pixels in 10µmx10µm.
“4” : “2SB” mode : Binning mode 2 x (2x2) which outputs the summation of 2 lines of 4k pixels in
10µmx10µm.
“5” : “4SB” mode : Binning mode (4x4) which outputs 1 line of 2k pixels in 20µmx20µm.
Binning modes
Full Exposure Control
As the « 4S » mode is performing an internal Time delay exposure on the lines A & B and C &
D, normally, the variation of the Exposure time should not be possible in this sensor mode.
Thanks to an e2v licensed solution, two of the Exposure controlled mode (Ext Trig with
internal or External exposure control) are still available in 4S sensor TDE mode.
The two binning modes 1SB and
2SB give an output of 4k pixels
10x10µm.
As for the 2SB mode, the
sensor manages the delay
between the two exposures
necessary for a “good match”
acquisition.
The 4SB is a binning 4x4 with
an output of 2K pixels
20x20µm
