Line Hopping Mode - Dalsa 1M28-SA User Manual

1M28, 1M75, and 1M150 User's Manual
Overlapping windows are not allowed and can result in errors in the image or interruption of the
image acquisition. In the latter case, MROI mode must be disabled before data acquisition can
continue.
The maximum frame rate in MROI mode depends on the number of rows and columns being read
out. See section 1.12 Calculating Frame Rate for information on the calculation of frame time.

1.10 Line Hopping Mode

Another possible way to increase the image data rate is to jump over lines (Line Hopping). In Line
Hopping mode, the camera delivers a pseudo-image to the framegrabber consisting of the
composition of individual selected lines. The 1MXXX camera family allows you to define the
