Acquisition Mode
In the SP-20000M-USB and SP-20000C-USB, the following three acquisition modes are available.
Single frame :
Multi frames :
Continuous :
7.1.1.1
Single Frame
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, single frame mode is not available.
◆ 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)
5) Output is stopped
Note: This figure is if the trigger mode is OFF, and when the trigger mode is
ON, FrameActive becomes True at 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.
Associated functions: AcquisitionStart、AcquisitionStop
SP-20000M-USB / SP-20000C-USB
One frame can be output by AcqusitionStart command
The number of frames specified in Acquistion Frame Count, are
output by AcquisitionStart command
Images are continuously output by AcquisitionStart command until
AcqusitionStop command is input.
