Feature description 34
5.2.5 ROI / AOI
In Partial Scan or Area-Of-Interest or Region-Of-Interest (ROI) -mode only
a certain region of the sensor will be read.
AOI on a CCD sensor
Selecting an AOI will reduce the number of horizontal lines being read.
This will reduce the amount of data to be transferred, thus increasing the
maximum speed in term of frames per second.
With CCD sensors, setting an AOI on the left or right side does not affect
the frame rate, as lines must be read out completely.
With CMOS Sensors, AOI can be selected as well. Please note, most
CMOS sensors require the camera to read full horizontal sensor lines
internally. Reducing horizontal size with AOI might result in limited fps
speed gain.
