6.3.3 AOI
{Area of Interest} and Up-Scaling
When the FPS is modified the default AOI (maximum allowed) is set for the selected
FPS. By reducing the AOI you can increase the available record time. To set a
Custom AOI push the Button next the the AOI indicator.
You will see the AOI selection screen as below :
You can enter the desired AOI by changing the value for width and height.
Special Considerations & Limitations
The AOI must conform to the following restrictions:
1) Width (W) must be a multiple of 8
2) Height (H) must be a multiple of 8
3) Total area (pixels) i.e., W x H must be a multiple of 1024
The software will AUTOMATICALLY adjust your input to meet these criteria. To meet
Criteria 3 it will adjust the width or height that you are NOT currently specifying. For
Example, if you change the width to a value that does not meet criteria 3 then the
HEIGHT
will be automatically adjusted to meet this criteria.
