Review of Camera Performance and Features
Spatial Correction
See Camera Control Category in Appendix A for GenICam features associated with this section and
how to use them.
Relevant Features:
The RGB+NIR camera has a quadlinear configuration
—
each set of color rows are spatially
separated by three rows except for the NIR row which has 5 row spacing.

The camera ensures the scan direction alignment of the three colors by delaying the image data for
each color a set amount of time, as dictated by the scan direction.
If the encoder generates a pulse that is equal to the object pixel, the spatial correction value used
by the camera will be 1. However, guaranteeing the encoder pulse accuracy may not always be
possible. In addition, lens magnification may not be exact
—
which will introduce a similar error.
The camera has a Spatial Correction feature that can correct for these small encoder or
magnification errors on a sub-pixel level. The user can enter a floating-point number from 0 to
15.996 in order to perform the spatial correction. The sub-pixel spatial correction resolution is
