Calculating the Maximum Frame Rate for a Given Exposure Time
To determine the camera’s maximum allowed frame rate at a given exposure time, use the formula
below. This formula applies when the camera is set for full resolution.
Example 1
Assume that the camera is set for full resolution, 8 bit output and an exposure time of 6.50 ms.
Max frame/s = 22.7
The maximum allowed frame rate in this case is 22.7 frames per second.
Example 2
Assume that the camera is set for full resolution, 8 bit output and an exposure time of 1.10 ms.
Max frames/s = 25.9
The formula returns a value of 25.9 fps, but the 1394 bus capacity limits the maximum frame rate
at full resolution with 8 bit output to 25 fps. So in this case, the maximum allowed frame rate
is 25 fps.
L
When the camera is operating at full resolution and 8 bit output, the 1394 bus capacity
limits the maximum frame rate to 25 fps. If the formula returns a value higher than 25,
the maximum will frame rate will be limited to 25.
When the camera is operating at full resolution and 16 bit output, the 1394 bus ca-
pacity limits the maximum frame rate to 12.5 fps. If the formula returns a value higher
than 12.5, the maximum will frame rate will be limited to 12.5.

The information on this page is valid when you are operating the camera at full reso-
lution. If you use the camera’s AOI feature to reduce the resolution, you can operate
the camera at higher frame rates. See Section 3.7 for more information about the AOI
feature.
