7.12.3 Removing the Frame Rate Limit (acA640-120 Only)
Normally, the maximum frame rate that an acA640-120 camera can achieve with a given group of
parameter settings is as described in the previous section. In this normal situation, the maximum
frame rate is limited by the standard operating ranges of several of the electronic components used
in the camera. The goal of remaining within these standard operating ranges is to ensure that the
camera provides optimum image quality.
If you desire, you can use the remove parameter limits feature to remove the maximum frame rate
limit on your acA640-120 camera. If you remove the frame rate limit, the electronic components will
be allowed to operate outside of their normal operating ranges. With the limit removed, you will find
that the maximum allowed frame rate at full resolution will increase and that the maximum allowed
frame rate with smaller AOI settings will also increase proportionately.
If you do remove the maximum frame rate limit, you may see some degradation in the overall image
quality. In many applications, however, the benefits of an increase in the maximum allowed frame
rate will outweigh the drawbacks of a marginal decrease in image quality.
1. Read the value of the Resulting Frame rate parameter with the maximum frame rate limit
enabled.
2. Use the remove parameter limits feature to remove the limit.
3. Read the value of the Resulting Frame rate parameter with the limit removed.
For more information about
using the remove parameter limits feature, see Section 10.15 on page 295.
the resulting Frame Rate parameter, see page 152.
To determine how much removing the frame rate limit will affect max. allowed frame rate:
