    • Defect Pixel Correction 

      Næs, Eirik Skogestad (Master thesis, 2010)
      A problem with image sensors today, is that they contain defect pixels. By utilizing an image processing algorithm for defect pixel correction, image quality can be increased and costs per produced sensor can be reduced.This ...
    • Defective Pixel Correction 

      Backe-Hansen, Henrik (Master thesis, 2010)
      When using CMOS technology for image sensors, there is a possibility that any givenpixel is defective and will thus produce a value that does not correlate to the amount oflight it was subject to. As such, the processing ...
    • Delay-Fault BIST in Low-Power CMOS Devices
