Camera Performance and Features
Spatial Correction
Spatial correction is necessary when using HDR or high full well modes. For single array TDI
operation this functionality is not needed and is disabled.
To achieve a sharp image in the vertical direction when running the camera in HDR mode, it is
important that the lines being used are aligned correctly. Line spatial correction is used to ensure
that these lines align.
Spatial correction is not necessary when using the camera with the main array only.

Figure 9. Camera Line spacing
The camera ensures the scan direction alignment of the lines by delaying the image data for each
row a set amount of time, as dictated by the scan direction. The camera automatically adjusts the
true spatial correction values depending on direction. Spatial correction is then performed in the
frame grabber based on the time stamps provided by the camera. Note: the frame grabber must
be set to two planes to align the data.
