Figure 7.7: MV1-D1312-160 LUT panel Grey level transformation is remapping of the grey level values of an input image to new values which transform the image in some way. The look-up-table (LUT) is used to convert the greyscale value of each pixel in an image into another grey value.

    7.1.7 LinLog This tab contains LinLog and Skimming settings. Figure 7.8: MV1-D1312-160 linlog panel LinLog The LinLog technology from Photonfocus allows a logarithmic compression of high light intensities. In contrast to the classical non-integrating logarithmic pixel, the LinLog pixel is an integrating pixel with global shutter and the possibility to control the transition between linear and logarithmic mode (Section 4.2.2).

    7.1.9 Correction This tab contains correction settings. Figure 7.10: MV1-D1312-160 correction panel Correction Mode This camera has image pre-processing features, that compensate for non-uniformities caused by the sensor, the lens or the illumination. Off: No correction. Offset: Activate offset correction Offset + Hotpixel: Activate offset and hot pixel correction.
  • Page 102 7 Graphical User Interface (GUI) Calibration Offset (FPN), Hotpixel Correction: The offset correction is based on a black reference image, which is taken at no illumination (e.g. lens aperture completely closed). The black reference image contains the fixed-pattern noise of the sensor, which can be subtracted from the live images in order to minimize the static noise.

In free-running mode it counts all pulses received from interface trigger or from I/O trigger interface. Missed Burst Trigger: This is a counter for burst trigger pulses that were blocked because the burst trigger pulse was received during the last burst is not yet finished.

    Mechanical and Optical Considerations 8.1 Mechanical Interface During storage and transport, the camera should be protected against vibration, shock, moisture and dust. The original packaging protects the camera adequately from vibration and shock during storage and transport. Please either retain this packaging for possible later use or dispose of it according to local regulations.
