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

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