Area of Interest (AOI) Setup
The Area of Interest (AOI) feature can be used to reduce the amount of image-data output from the
camera. Use this feature when there are areas in the image that contain unneeded information.
An example where you would use this feature is in an application that is inspecting several separated
lanes of objects with one camera and the image between the lanes can be ignored.
The AOI feature allows from one to four specific areas of the pixel line to be specified where image data
will be output. Since the AOI feature reduces the amount of data output, this has the additional benefit of
allowing the cameras to operate at higher EXSYNC rates when using base, medium, or full camera link
modes.
For example, if the total number of pixels for the specified AOI`s is less than 1 K when using base Camera
Link mode at 85 MHz, the maximum EXSYNC rate can be 70 KHz; versus 20 KHz if all 4 K pixels were
output.
Note:
The setup of AOI is always with respect to the sensor. Therefore, if you are using the mirroring
mode with AOI, be aware that pixel one will be on the right side of the displayed image.
In order to set up an AOI for the camera:
1.
The AOI mode must first be in the off position.
2.
Use the AOI Count to select the total number of AOIs desired to a max of 4.
3.
To set up each AOI individual use the AOI Selector to point to the AOI to be set up.
4.
AOI Offset X is used indicate the starting pixel of the AOI.
5.
AOI Width is used to indicate the width of the that AOI.
