3.7.1 AOI Setup Guidelines

When setting up the area of interest, several guidelines must be followed. The setup rules are

listed below.

• The starting line must be an odd numbered line and the starting column must be an odd num-

bered column.

• The number of columns included in the AOI must be divisible by 2 the number of lines

included in the AOI must be divisible by 2.

• The sum of the setting for the Starting Column plus the setting for the Width in Columns can

not exceed 1005.

• The sum of the setting for the Starting Line plus the setting for the Height in Lines can not

exceed 1005.

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 1004, the starting line

should be set to 1, and the height in lines should be set to 1004.

3.7.2 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. The maximum allowed frame rate can be calculated using the following

formula:

Where: LI = the number of lines included in the area of interest

Maximum Frames per Second

1,000,000 µs

(LI x 20.55 µs) [ (1004 - LI) x 7.3 µs ] 204.8 µs++
