When viewing a scene with a low-temperature span, the image from the 14-bit signal can sometimes be difficult to interpret because of the low contrast. This is caused by the fact that while the image is using the full range of the detector (14 bits), the important information is contained in only a very small portion of this range.

With eBUS SDK version 4.1.4 (available at Pleoras), histogram equalization of the stream being viewed can be performed. To activate histogram equalization, press Tools, Image Filtering... and then select the Enable box.

This will make the histogram visible and allow you to draw Dark and Light markers at the desired positions or to use Auto Configure.

In this histogram, it is obvious that only a small portion of the detector's full 14-bit span is utilized, i.e., the contrast is very low. By using histogram equalization, it is possible to vastly increase the contrast.

It is also possible to increase the contrast by viewing the 8-bit stream instead of the 14-bit stream. This can be achieved by changing the GenICam register PixelFormat to 8 bits. This is an alternative way of increasing the contrast if you are using an old version of the eBUS SDK and don't want to update to version 4.1.4.
