              Testing the BIP – Part 2

              Colour Table
              Basler IP Cameras are known for their outstanding image quality. But this image quality does not come easily – rigorous testing in our laboratory helps us judge the image quality of our cameras and select the most suitable lenses.

              In our test lab, we use software called Imatest Master that gives us detailed values for different camera characteristics. The findings gathered during the tests help us pick a suitable lens for any camera type and also influence the development of our IP cameras and their firmware.

              Color Check

              Using Imatest's color check module, we can assess our cameras' color fidelity. For this purpose, a camera captures an image of a standard color chart. The software then evaluates deviations in the camera image colors from the colors on the chart.

              Other tests provide data on a camera's dynamic range, i.e., the camera's ability to reproduce very bright and very dark image areas, and on the distortion that occurs in a specific lens. The dynamic range can be determined with a transmission test chart attached to a lighting panel. The camera captures an image of the backlit test chart. From this image, it becomes evident how the camera reproduces very bright and very dark areas. Alternatively, dynamic range can also be measured with an illuminated reflection chart. The camera needs to capture three images of the reflection chart with different aperture settings. The dynamic range is then calculated using mathematical formulas.
