3.8.1 AOI Setup Guidelines
When setting up the area of interest, a few guidelines must be followed:
• The sum of the setting for the Starting Column plus the setting for the Width in Columns can
not exceed 1393.
• The sum of the setting for the Starting Line plus the setting for the Height in Lines can not
exceed 1041.
In normal operation, the camera is set to use all of the pixels in the array. To use all of the pixels,
the starting column should be set to 1, the width in columns should be set to 1392, the starting line
should be set to 1, and the height in lines should be set to 1040.
3.8.2 Changes to the Maximum Frame Rate with Area of Interest
When the area of interest feature is used, the camera’s maximum allowed frame rate increases.
The amount that the maximum frame rate increases depends on the number of lines included in
the area of interest. The smaller the number of lines in the area of interest, the higher the
maximum frame rate.
3.8.2.1 With Vertical Binning Disabled
The maximum allowed frame rate can be calculated using the following formula:
Where: AOIH = the number of lines included in the area of interest
3.8.2.2 With Vertical Binning Enabled
The maximum allowed frame rate can be calculated using the following formula:
Where: AOIH = the number of lines included in the area of interest
