ABSTRACT:
The invention provides a filter circuit for use with a real-time video image converter. The filter circuit interpolates among a first sequence of digital pixel values and decimates among the interpolated sequence to generate a second sequence of digital pixel values with a desired granularity. Interpolation and decimation are preferably computed using weighted averages of digital pixel values.
