Bayer Area Scan Color Cameras compared to 3-CCD Color Cameras, part 2

With advances in filters, color processing, and overall sensor control by experienced camera designers, the shortcomings for single chip (Bayer filter mosaic) color cameras compared to 3-chip prism-based color cameras have nearly been eliminated.  We have compared the different technologies with regards to image quality and color fidelity.  Here we will compare with regards to…

Enhancing existing ALPR systems using smear reduction in the camera

Image sensors designed for machine vision applications are proving beneficial in traffic systems, such as automatic license plate recognition systems, because of their exceptional image quality and reliability in extended temperature ranges.  Except, these image sensors are optimized for use under controlled lighting conditions and have challenges in outdoor lighting conditions especially extreme situations such…

Repeatability and reproducibility for precision machine vision, medical, and global security systems

For OEMs building systems in series production, whether in machine vision equipment, medical devices, or global security products; repeatability and reproducibility of the cameras can be just as important as raw performance.  Image uniformity can influence the accuracy of the system or the degree of closeness of measurements to the actual (true) value.  But the…
