A method for encoding high resolution data to a form having a reduced
number of bits can include predefining a plurality of
high-output-resolution output patterns, associating respective
output-resolution output patterns of the plurality with respective
encoded resolution bit patterns, receiving a block of input-resolution
input data, determining a respective difference between a pattern of the
received block of input data and the respective output-resolution output
patterns, selecting a respective output-resolution output pattern
associated with a lowest respective difference to be a representative
output pattern for the received block of input data and encoding the
received block of input-resolution input data as the respective encoded
resolution bit pattern associated with the selected respective
representative high-output-resolution output pattern. A system includes a
library of output patterns in association with encoded resolution bit
patterns, a block analyzer, a block selector and an encoder.
