Now something about that always bothered me because I just can't understand how you can keep turning these big pixels into sharp lines. "Thats Impossible!" I would shout at the television. How can they do it? I wonder if it's technology that is just beyond my understanding. Well, I guess I'm starting to understand how
They seem to be using a method called Interpolation to enhance the image. It actually gives a more accurate representation of the image the camera was attempting to capture.
I learned a few things at Smart Guy's Website about the algorithms they use to process these images and enhance them.
" The various algorithm's then divide the original large pixel into a number of smaller pixels whoose new values are derived (interpolated) from the shared values of the original adjacent pixels. Bilinear Interpolation multiplies the original pixel into four, Dipietro and Molenaar's S.P.I.T. multiplies it into eight, and the "Cubic Spline" method used by Carlotto uses twelve surrounding pixels.
This is, in effect a statistical analysis of the data provided by the pixel relationships. "
