Column Interpolation Correction (True Color Only); Line Interpolation Correction (True Color Only); Effects Of The Interpolation Corrections In True Color - e2v UNIIQA User Manual

2.2.3 Column Interpolation Correction (True Color Only)

This interpolation is used to compensate the colour error in the Red or the Blue in case of a
vertical transition on the web : The Red of the blue value of each coloured pixel is corrected
if the variation between two neighbour green pixels is significant.
α α
B ' = x B and is the blue correction, calculated with the variation (G
1 B 1 B
α α
R ' = x R and is the red correction, calculated with the variation (G
2 R 2 R

This interpolation is available only for pixel size 10x10µm (True Color)

It can be disabled by the customer. By default, it is enabled.

2.2.4 Line Interpolation Correction (True Color Only)

This interpolation is used to compensate the colour error in the Red
or the Blue in case of a horizontal transition on the web in the same
"True Color" pixel : A line is memorized and the Red of the blue
value of each coloured pixel is corrected if the variation between
two consecutive green values (previous to next line) is significant :
α α
B ' = x B and is the blue correction, calculated with the
1 B 1 B
variation (G –G' )

R ' = x R and is the red correction, calculated with the


This interpolation is available only for pixel size 10x10µm (True Color)

It can be enabled by the customer. By default, it is disabled

This interpolation requires the Forward/Reverse indication sent to the camera for the memorized line.
The Line Interpolation has to be disabled if the light is changing for each Line (typically for
pulsed Light source with different spectrum) or for any reason the Green component of
the light source changes significantly from one line to the next one.
