Line Capture Modes

This board provides two line capturing methods. The line capture mode is user-selectable by means of LineCaptureMode:

LineCaptureMode

Description

ALL

"Take-All-Line" line capture mode

The board acquires all the lines delivered by the camera providing that the acquisition channel is active and the trigger conditions are satisfied.

If the downweb motion speed is varying, the line-scanning process of the camera should be rate-controlled accordingly.

This is the default line capture mode.

PICK

"Pick-A-Line" line capture mode

Each pulse occurring at the downweb line rate determines the acquisition of the next line delivered by the camera providing that the acquisition channel is active and the trigger conditions are satisfied.

This downweb resampling method allows the camera to be operated at a constant line rate while acquiring lines at a variable downweb line rate.

The relevant and the applicable values of LineCaptureMode depend on the two following prerequisites settings: Imaging, CamConfig.
