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 (for examples see table below).
