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 589fps).
