1. A pattern recognizing apparatus comprising: layout analyzing means for analyzing a layout of an input image, wherein ruled lines, character boxes and black-character-box-touching characters are extracted; quality analyzing means for analyzing a quality of the input image, wherein obscure characters are detected by both of a global quality analysis and a local quality analysis; correction analyzing means for analyzing a correction state of the input image, wherein deletion lines are extracted from the input image; pattern recognizing means for performing a pattern recognizing process on each state of a process object of the input image, said pattern recognizing means comprising a recognizing dictionary provided for each quality of characters, and recognizes the characters by appropriately utilizing a plurality of recognizing dictionaries based on a quality analyzed by said quality analyzing means, said recognizing dictionary comprising at least one of a standard dictionary, an obscure-character dictionary, a deformed-character dictionary, a framed-white-character dictionary, and a texture-background-character dictionary, wherein character recognizing processes of basic character recognizing process, character string recognizing process, box-touching character recognizing process, obscure character recognizing process and deformed character recognizing process, and non-character recognizing processes of deletion line recognizing process and noise recognizing process are performed; and environment recognizing means for performing a recognizing process by extracting the state of the process object of the input image based on the layout quality or correction state, and selecting one or more pattern recognizing processes which will be performed for each state of the process object.
