Method of pattern recognition and apparatus thereof
 In an apparatus for pattern recognition provided with convertion means for converting a two-dimensional image carried on a picture into pattern signals, memory means for temporally storing the pattern signals from said convertion means, and recognition means for recognizing the pattern signals read out from said memory means, disclosed is a method wherein said picture is divided into a plurality of partial pictures in a manner that adjacent ones of the partial pictures hold in common a partially overlapped region, said convertion means convert, on a one-by-one basis of the partial pictures, the two-dimentional image into pattern signals to be stored in said memory means, and the stored pattern signals are, on a one-by-one basis of the partial pictures, read out to be recognized by said recognition means.
