Enhancement of Interest (EOIs) Regions
Reduce Image Data & Enhance Performance
See the section Flat Field Category in Appendix A for GenICam features associated with this section
and how to use them
Related Features:
Enhancement of Interest (EOI) regions allow rapid gain and offset settings to be applied to up to 4
regions in the image. EOIs are supported in all imaging modes except for Super Resolution mode.
The EOI feature has been optimized to load in minimum time (~ 50 ms) by only applying a gain
and offset on a region rather than per-pixel.

EOIs are designed for applications where maximum line rate is a priority and pixel flatness for the
region is tolerable, as compared to HDR mode or regional flat field correction (FFC), which provide
per pixel adjustments.
For example, if image has regions that are highly reflective and other regions that are dark, the
response in a region can be adjusted to flatten the output. HDR mode or regional FFC can
compensate for this by applying a per-pixel based correction, providing the best result for a flat
image. However, HDR limits the maximum line rate due to dual line acquisition and FFC requires
greater than 2 seconds to load user set coefficients and cannot be used to adjust to changes in
image regions in real-time. Alternatively, EOIs provide the maximum line rate but with a flattened
image region.
Note:
EOI parameter settings are not stored in the camera and are erased at
camera reset.
