Changes To The Frame Rate With Aoi - Basler A101f User Manual

On the A101
On all cameras, the sum of the setting for Left plus the setting for Width must not
exceed 1300.
On all cameras, the sum of the setting for Top plus the setting for Height must not
exceed 1030.
On all cameras, the AOI must contain at least 6144 pixels (width x height).

3.8.1 Changes to the Frame Rate With AOI

When the area of interest (AOI) feature is used, the maximum allowed frame rate depends on the
number of rows included in the area of interest. The maximum allowed frame rate increases as
the number of rows included in the area of interest decreases. The formula below can be used to
calculate the maximum allowed frame rate when the AOI feature is used:
Frames/sec. =
Table 3-1 shows the maximum allowed frame rates for a variety of AOI sizes.
Rows in AOI
1000
900
800

Table 3-1: Maximum Allowed Frame Rates
The examples in Table 3-1 assume that you are using the maximum allowed packet
size. If you use a smaller packet size, you will not be able to achieve the stated frame
rates. See Section 3.12.2 for more details.
