Camera Operation Modes

The classification of the operation modes of the industrial cameras is based on the following MultiCam parameters: Expose and Readout.

The enumerated parameter Expose specifies the camera exposure principle used by the camera; possible values are:

Value	Description
INTCTL	The line or frame exposure condition is totally controlled by the camera. The exposure duration is set through camera configuration settings.
PLSTRG	The line or frame exposure condition starts upon receiving a pulse from the frame grabber.
WIDTH	The duration of a pulse issued by the frame grabber determines the line or frame exposure condition.
INTPRM	The exposure is permanent.

The enumerated parameter Readout specifies the camera readout principle used by the camera; possible values are

Value	Description
INTCTL	The frame read-out condition is totally controlled by the camera. The read-out duration is set through camera configuration settings.

The MultiCam Channel must be configured for the appropriate camera operation modes by assigning the appropriate values to the Expose and Readout parameters.

Operation Modes of Area-Scan Cameras

The following table shows the valid combinations of values for area-scan cameras (Imaging = AREA) are listed hereafter:

Short name	Expose	Readout	Description
PxxSC	INTCTL	INTCTL	Synchronous progressive scan, camera-controlled exposure
PxxRC	PLSTRG	INTCTL	Asynchronous progressive scan, camera-controlled exposure
PxxRG	WIDTH	INTCTL	Asynchronous progressive scan, grabber-controlled exposure

Note. Scanning = PROGRESSIVE does not need to be set since only one value is supported.

Operation Modes of Line-Scan Cameras

The following table shows the valid combinations of values for (non-TDI) line-scan cameras (Imaging = LINE) are listed hereafter:

Short name	Expose	Readout	Description
LxxxxSP	INTPRM	INTCTL	Free-running or camera-controlled line rate Permanent exposure or disabled electronic shutter No control line
LxxxxSC	INTCTL	INTCTL	Free-running or camera-controlled line rate Camera-controlled exposure with electronic shutter Single control line
LxxxxRP	INTPRM	PLSTRG	Grabber-controlled camera line rate and exposure Permanent exposure or disabled electronic shutter Single control line
LxxxxRC	PLSTRG	INTCTL	Grabber-controlled camera line rate camera controlled exposure Single control line
LxxxxRG	WIDTH	INTCTL	Grabber-controlled camera rate and exposure Camera-controlled exposure with electronic shutter Single control line
LxxxxRG2	PLSTRG	PLSTRG	Grabber-controlled camera rate and exposure Camera-controlled exposure with electronic shutter Two control lines

Operation Modes of TDI Line-Scan Cameras

The following table shows the valid combinations of values for TDI line-scan cameras (Imaging = TDI) are listed hereafter:

Short name	Expose	Readout	Description
LxxxxSP	INTPRM	INTCTL	Free-running, permanent exposure
LxxxxRP	INTPRM	PLSTRG	Grabber-controlled line-scanning, permanent exposure
