Partial Scan
Cameras provide a certain resolution which is dictated by the image sensor. Often, a certain region may be of
interest to the user. Partial scan mode provides the function to capture a certain region of interest (ROI) which
can provide an advantage in data transfer speed, resulting in a faster operation. As described in binning mode, the
speed gain would occur only if vertical resolution decreases. Partial Scan is only supported in Format 7 by setting
the following registers described in the IIDC1.31 specification. Unit size of the partial scan is described in the
camera specification, which the user must consider in setting the increment configuration.
IMAGE POSITION & IMAGE SIZE register
Left = Hposunit * n1
Top = Vposunit * m1
Width = Hunit * n2
Height = Vunit * m2
Left + Width < = Hmax
Top + Height < = Vmax
(n1,n2, m1, m2 are integer)
