Parameter Description

In line-scan system, this parameter declares the fundamental line capturing mode.

Parameter Usage

Relevance condition(s):
  • Condition: Any line-scan acquisition mode.

Parameter Values

Enumeration: ADR, PICK, ALL, TAG

Table 1. ADR
MC_LineCaptureMode_ADR

Applicable product(s): 1198 Grablink Avenue, 1621 Grablink Express.

Description

Advanced Downweb Resampling line capture mode.

The line-scanning process of the camera is running at a constant rate. Each pulse occurring at the down-web line rate determines the computation of a line from a set of presently recorded lines delivered by the camera.

Default value.

Table 2. PICK
MC_LineCaptureMode_PICK

Applicable product(s): 1191 Grablink Value, 1198 Grablink Avenue, 1621 Grablink Express, 1624 Grablink Base, 1623 Grablink DualBase, 1622 Grablink Full, 1626 Grablink Full XR.

Description

Pick-a-line line capture mode. The line-scanning process of the camera is running at a constant rate. Each pulse occurring at the down-web line rate determines the acquisition of the next line delivered by the camera.

Table 3. ALL
MC_LineCaptureMode_ALL

Applicable product(s): 1191 Grablink Value, 1198 Grablink Avenue, 1621 Grablink Express, 1624 Grablink Base, 1623 Grablink DualBase, 1622 Grablink Full, 1626 Grablink Full XR.

Description

Take-all-lines capture mode. Each delivered camera line results into a line acquisition. This is the traditional operating mode. If the down-web motion speed is varying, the line-scanning process of the camera should be rate-controlled accordingly

MC_LineCaptureMode_TAG

Applicable product(s): 1624 Grablink Base, 1623 Grablink DualBase, 1622 Grablink Full, 1626 Grablink Full XR.

Description

Tag-A-Line capture mode. The line-scanning process of the camera is running at a constant rate determined by Period_us.

The down-web line rate is determined by the pulse rate of A/B signals delivered by an external encoder and processed by the quadrature decoder and the rate divider.

The frame grabber captures all lines delivered by the camera after having replaced the first pixel data by a tag indicating that the line was preceded or not by an hardware event on the divider output.
