8.3.17. Remove Parameter Limits
The range of camera parameters is usually limited, and these factory limits are designed to ensure the
best camera performance and high image quality. However, for certain use cases, you may want to specify
parameter values outside of the factory limits. You can use the remove parameter limits feature to expand
the parameter range. The features of the extended range supported by different cameras may be different
and the range may be different, as shown in Table 8-7.
