Abstract : A Gaussian convolution is produced in a CCD imager or shift register by a method involving a special clocking sequence. The principle of operation, analagous to the process of diffusion, involves the deliberate intermixing of adjacent charge packets in a controlled way. Amounts of charge are exchanged between adjacent pixels a number of times, the result approximating the convolution of the image with a Gaussian function whose width is dependent upon the number of mixing cycles.
