MATRIX 220
High Dynamic Range (HDR) feature
All Matrix 220 models support the High Dynamic Range (HDR) feature. HDR performs an
image dynamic correction where low intensity pixel values are enhanced, thus improv-
ing image contrast and code readability.
This feature proves particularly useful in the following cases:
• To adjust contrast when the outer area of the image is
less exposed than the cen-
tral area because of a large Skew
angle:
HDR disabled HDR enabled
• To adjust contrast when a DPM illuminator is used. In this case, at short distances
(e.g. 50 mm) the image contrast in the FoV may result heterogeneous. The HDR
feature helps normalize image contrast allowing the use of Standard Contrast
decoding:
