Acquisition Control
The Acquisition Control section describes all features related to image acquisition, including the
trigger and exposure control. It describes the basic model for acquisition and the typical behavior of
the device.
An
Acquisition
is defined as the capture of a sequence of one or many
Frame
(s). This Acquisition mode
and its command is managed by the Frame Grabber.
A
Frame
is defined as the capture of
Width
pixels x
Height
lines.
As for the Acquisition Mode, the
Frame Management
(Start, stop …) is also manage by the Frame
Grabber.
The CXP Camera is considered as a LineScan Camera (as in the CameraLink version) then only
deals with the Line/Exposure Triggers.
A
Line
starts with an optional
Exposure
period and ends with the completion of the sensor read out.
The Line/Exposure Triggers can be connected :
-
Either on the GPIO connector of the Camera (2x Lines Triggers : Line0/1 available if
Forward/reverse command is controlled by software)
-
Or by the CoaxPess Cable : Only one Trigger available (Line2).
If the single CoaxPress Trigger is used, the Synchronization mode using 2xTriggers can’t be used.
