摘要

PROBLEM TO BE SOLVED: To detect space in an alphanumeric character string which exits mixedly with a Japanese character string with high precision by picking-up the alphanumeric character string from a character recognition result as an object range, discriminating a pitch format at every object area and executing a space detection processing by pitch format for every object range. ;SOLUTION: At first, in an object range pick-up part 204, the character recognition result inside a result memory 211 is referred and the alphanumeric string as the object range of the space detection processing is picked-up. Information concerning the picked-up object range is preserved in a work memory 212. Then, in a pitch format judging part 205, the contents of a segmenting memory 209 and the result memory 211 are referred concerning the character of the object range and it is judged whether the object range is a proportional pitch or a constant pitch. The judgement result is preserved in the work memory 212. A constant pitch character string space detection processing or a proportional pitch character string space processing is executed in accordance with the judgement result.;COPYRIGHT: (C)1997,JPO
