Region of Interest
With Region of Interest (ROI) a region in the pixel array can be selected to read-out
from the pixel array from the sensor and transferred to the host system as shown in
the figure below.
Figure Image size and defining a Region of interest
The sensor provides SensorWidth times SensorHeight pixels.
Within the shrunk image the user can set a Region of interest using the features
OffsetX, OffsetY, Width, and Height. The resulting image generated by the device has
Width time Height pixels. OffsetX and OffsetY are given with respect to the upper left
corner of the image which has the coordinate (0, 0) (see Figure).
