Linea GigE Series Camera
Trigger Overview
Linea GigE line exposures are initiated by a trigger event. A trigger is either the camera's
programmable internal clock used in free running mode, an external input used for synchronizing
exposures to external triggers, or a programmed function call message by the controlling
computer. These triggering modes are described below.
•
Free running — Line or Frame (Trigger Mode=Off): The Linea GigE free-running mode has
programmable internal timers for line rate/exposure period and frame rates. Line rate and
frame rates are independent. Frame free running simply means acquire all lines.
•
External trigger (Trigger Mode=On): Exposures are controlled by an external or internal
trigger signal where the specific input line or source is selected by the Trigger Source feature.
External signal inputs have a time programmable debounce circuit.
•
Virtual Frames: For any exposure type the virtual frame (i.e. the number of exposure lines per
frame is set by the Image Format Height feature of the Image Format Category).
Trigger Selector Details
•
Single Frame Trigger(Start) “FrameStart”: Starts the acquisition of one frame when the
acquisition is active. The number of lines in the frame is defined by the feature “Height”.
•
Frame Active Trigger “FrameActive”: Starts acquisition of one frame when the acquisition is
active. The number of lines in the frame is controlled by the trigger signal width.
•
If the frame active trigger period is greater than the feature “Height” value, the frame
acquisition is limited to the “Height” lines value and then waits for the next frame active
trigger.
•
If the frame active trigger period is less than the feature “Height” value, the frame
acquisition is limited to the lines within the trigger width period and then waits for the next
frame active trigger.
•
MultiFrame Trigger(Start) “FrameBurstStart”: Burst start trigger starts the capture of a
number of frames of “Height” lines. No line is lost between frames. The number of frames in
this burst mode is defined by the feature “AcquisitionBurstFrameCount”.
•
Frame Burst Active Trigger “FrameBurstActive”: Frame burst active trigger is used for
multi-frame acquisitions. The number of lines in a frame is controlled by the width of the
trigger, up to the value “Height”.
