1. A pattern re-recognizing table generating apparatus comprising: pattern separating means for separating a pattern from an image formed by the pattern touching a line; pattern recognizing means for recognizing the pattern separated by said pattern separating means; reliability calculating means for calculating reliability data of the pattern recognized by said pattern recognizing means for a state of the pattern touching the line; table generating means for generating a table for storing reliability data together with a set of patterns including a pattern misrecognized by said pattern recognizing means and an expected pattern, for a line-pattern touching state, with the reliability data calculated by said reliability calculating means.
