7.1. Acquisition control
7.1.1 Acquisition Mode
In the SP-5000-USB, the following three acquisition modes are available.
Single frame :
One frame can be output by AcqusitionStart command
Multi frames :
The number of frames which is specified in Acquistion Frame Count, are
output by AcquisitionStart command
Continuous :
Images are continuously output by AcquisitionStart command until
AcqusitionStop command is input.
7.1.1.1 Single Frame operation
In single frame mode, executing the AcquisitionStart command causes one frame to be captured.
After one frame is captured, this operation is automatically stopped.
In order to restart the capture, it is necessary to input the AcquisitionStart command again.
BlockID is not reset until AcquisitionStop is input and is incremented when the AcquisitionStart
command is called.
In the case of PIV operation, 2 frames are captured.
◆
Normal single frame operation
1) AcquisitionStart command is input
2) AcquisitionActive becomes “TRUE” (accepts capture)
3) 1 frame is output
4) AcquisitionActive becomes “FALSE” (stop capturing)
Note: This drawing shows if the trigger is OFF. If the trigger is ON, FrameActive turns to
True at a different AcquisitionActive timing.
◆
Forcing acquisition to stop
While AcquisitionActive is “TRUE”, if AcquisitionStop or AcquisitionAbort is
initiated, AcquisitionActive becomes “FALSE” (stop capturing).
However, if AcqusitionStop command is initiated during image output period,
AcqusitionActive becomes “FALSE” (stop capturing) after image output is completed.
