9.1.7 Region of Interest
With the "Region of Interest" (ROI) function it is possible to predene a so-called Region
of Interest (ROI) or Partial Scan. This ROI is an area of pixels of the sensor. On image
acquisition, only the information of these pixels is sent to the PC.
This function is employed, when only a region of the eld of view is of interest. It is coupled
to a reduction in resolution.
The ROI is specied by four values:
▪ Offset X - x-coordinate of the rst relevant pixel
▪ Offset Y - y-coordinate of the rst relevant pixel
▪ Size X - horizontal size of the ROI
▪ Size Y - vertical size of the ROI

In the illustration below, readout time would be decreased to 40%, compared to a full
frame readout.
