Abstract

This invention relates to a data conversion system utilizing a cell comprising: a shift register supplied with a plurality of data for sequentially shifting the data; a memory, supplied with data in a certain area of the shift register as addresses, storing data for outputting a predetermined value when data in the certain area are in a pattern to determine the value of the center dot of the area, or for outputting an instruction signal for determining the value of the center dot according to dot data outside of the certain area when data in the certain area are not in a pattern to determine the value of the center dot of the area; and an operation unit for selecting and outputting said predetermined value from said memory when no instruction signal is supplied from the memory and for outputting the value of the center dot by determining it from data outside the certain area per the instruction signal.
