Title: Character recognizing device
Inventor: MORI KAZUHIRO
IPC: G06K9/62
Filed: 1989-05-20
Abstract: PURPOSE:To obtain a good recognized result even if alignment for every character is difficult by taking matching while scanning a dictionary pattern in a rectangular area circumscribed with a character string. CONSTITUTION:A character recognizing part 4 takes the matching while scanning the dictionary pattern in the rectangular area circumscribed with the detected character string, and calculates similarity at an individual point, and obtains the recognized result, and obtains the sum of the similarity of the area where the obtained individual recognized result repeats the same recognized result in succession, and classifies it in order of the size of the sum, and outputs the corresponding recognized result. A coordinate information verifying part 5 verifies whether the recognized result is owing truly to a character or not on the basis of coordinate information such as a space between the characters or arrangement in a longitudinal direction, etc. Thus, even in the case where the exact alignment of every character to the dictionary pattern is difficult because of the contact of a binary picture in the character string picture whose space between the characters is narrow, the contact of miscellaneous pictures or the drop-out of the binary picture, the good recognized result is obtained.
