Set ROI

If you are only interested in a certain region of the image, you can set a Region of Interest (ROI) for
the camera. Setting Region of Interest can reduce the bandwidth of the image being transmitted.
Thus increasing the frame rate to some extent.
 The camera currently supports 1 ROI only, that is, there is Region 0 for Region Selector
parameter only.
 Region of interest can be set only when you stop real-time acquisition.
Click Image Format Control > Region Selector, and enter Width, Height, Offset X, and Offset Y.
 Width: it stands for horizontal resolution in ROI area.
 Height: it stands for vertical resolution in ROI area.
 Offset X: it refers to the horizontal coordinate of the upper left corner of the ROI.
 Offset Y: it refers to the vertical coordinate of the upper left corner of the ROI.
