Partial Scan (horizontal cropping)
Genie also can crop the acquisition horizontally by grabbing less pixels on each horizontal line.
Additionally a horizontal offset value will start the grab from any pixel count, as shown in the
following figure. Note that horizontal cropping does not increase the maximum frame rate due to the
CCD readout architecture.

Window ROI
Vertical and Horizontal Cropping can be combined to grab only a region of interest (ROI). Besides
eliminating post acquisition image cropping done by software in the host computer, a windowed ROI
grab reduces the bandwidth required on the Gigabit Ethernet link since less pixels are transmitted. See
"
CamExpert Image Buffer and ROI Parameters" on page 39 to use CamExpert to configure image
cropping.
