Image Input Terminal (IIT) designs may incorporate algorithms for reduction, magnification, and windowing. In some cases, bit rate multipliers may be used, in others, Random Access Memory (RAM) storage devices which store a precomputed pattern for reduction and/or windowing. Special counters may also be used to generate the bit patterns required for magnification and reduction.
