Character reader and recognizer with a specialized editing function

Abstract

The character reader device of the present invention is capable of reading as read data characters written in a portion corresponding to a given read field on a manuscript; detecting a reject character in the read data; generating a pattern image corresponding to the reject character; displaying the read data, the reject character, and the pattern image; computing the position of a display area for the read data; deciding whether or not the computed display area is overlapped with the display area for the pattern image; shifting the pattern image to the area which is the outside of the display area for the read data if overlapped; and displaying it on the latter area. The character reader device can therefore prevent a disadvantage in modifying the reject character if the display area for the pattern image of the reject character is overlapped with the display area for the read data of the read field including the reject field by shifting the display area for the pattern image to another area and thereby modify the reject character more efficiently.

What is claimed is: 
     
       1. A character reading apparatus for processing an input data sheet including character data, comprising: reading means for scanning the input data sheet and for photoelectrically converting the scanned input data sheet to image data;   image storing means for storing the image data;   character recognizing means for .[.comparing the image data stored in said image storing means with pre-stored known image data and determining whether results of the comparison exceed a predetermined level, wherein said image data having the comparison result exceeding the predetermined level are output as.]. .Iadd.outputting .Iaddend.recognized character data, and .[.said image data having the comparison result failing to meet the predetermined level are output as.]. .Iadd.for detecting and outputting .Iaddend.a reject character;   display means for displaying the recognized character data, an indicator mark in place of the reject character, and the reject character at predetermined positions on said display means, respectively, the reject character being displayed in a form of the image data stored in the image storing means;   display control means for displaying the reject character at a different predetermined position on the display means when the reject character overlaps the character data containing the reject character; and   reject character modifying means for modifying the reject character to a correct character.   
     
     
       2. The character reading apparatus according to claim 1, further comprising image disposing means for extracting a specific area from the image data in the image storing means, the specific area being an area comprising a character to be extracted. 
     
     
       3. The character reading apparatus according to claim 1, further comprising image disposing means for extracting a specific area from the image data from the image storing means, the specific area being an area including a word having a character to be extracted.
