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.
