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:
Table 3-1 shows the maximum allowed frame rates for a variety of AOI sizes.
*
On the A101fc color camera:
the setting for Left must be 0 or an even number.
the setting for Top must be 0 or an even number.
the setting for Width must be an even number.
the setting for Height must be an even number.
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).
Rows in AOI Highest Frame Rate Rows in AOI Highest Frame Rate
1000 12.4 Frames/sec. 500 23.2 Frames/sec.
900 13.7 Frames/sec. 400 28.1 Frames/sec.
800
15.2 Frames/sec. 300 35.5 Frames/sec.
700
17.2 Frames/sec. 200 48.4 Frames/sec.
600
19.8 Frames/sec. 100 75.8 Frames/sec.
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.
