Flat field correction on CMOS cameras – for better or for worse?

Flat-Field Correction (FFC) can be done with both CCD and CMOS-based cameras to correct for sensor artifacts, lens artifacts, and illumination artifacts (shading).  The purpose of flat field correction is to ensure image uniformity regardless of exposure. With CMOS sensor-based cameras, FFC is especially important to minimize or even remove sensor artifacts and improve the…

Binning to increase SNR and frame rate with CCD and CMOS industrial cameras

There are always small changes (at no additional product cost) that can be made to increase the performance of your machine vision camera and thus to your overall inspection or metrology system.  Binning is one example.  There has been a trend with latest generation image sensors to increase resolution while also reducing the pixel size…
