ABSTRACT:
A bit pattern conversion apparatus has bit vertical/horizontal conversion means for converting data at the same bit positions of n-bit data into n-bit data, double expansion conversion means for converting 1-bit data into 2-bit data and producing the 2-bit data, bit number conversion means for converting 8-bit data into 6-bit data, and MSB/LSB conversion means for performing MSB/LSB conversion. The bit pattern of data stored in the memory means by the decoder means is converted by each conversion means.
