Partial Scan—Window ROI
Partial Scan (vertical cropping)
The Partial Scan mode, also know as vertical cropping, reduces the number of video lines grabbed for
a frame. By not scanning the full vertical area of the sensor, the maximum possible acquisition frame
rate is proportionately increased (as an extreme example, the m640 scanning a one line frame, exposed
around 590 fps).
