Abstract

A 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 modify the reject character more efficiently.

Claims

1. A character reading apparatus for processing an input data sheet including character data, the character reading apparatus for use with a computer system including a display apparatus having a plurality of display areas including at least first and second display areas, the character reading apparatus comprising:

scanner means for scanning the input data sheet and for producing an output image data corresponding to the input data sheet;

character recognizing means for recognizing a character having a clarity of at least a predetermined level in the output image data;

reject character detecting means for detecting a reject character having a level of clarity below the predetermined level in the output image data;

pattern image generating means for reproducing a reject character image corresponding to the reject character;

position computing means for computer a display position on the display apparatus in accordance with the recognized character and the reject character;

display control means for displaying an image of each of the recognized character and the reject character in accordance with the display position from the position computer means, and for selectively displaying the reject character image in the first display area or the second display area;

decision means for determining whether the displayed reject character overlaps the first display area; and

shifting means for shifting the displayed reject character image to the second display area when the decision means determines that the displayed reject character overlaps the first display area.

2. The character reading apparatus according to claim 1, further comprising:

storing means for temporarily storing the displayed recognized character when the displayed reject character overlaps the displayed recognized character in the second display area when the reject character image is shifted to the second display area.

3. The character reading apparatus according to claim 1, wherein the scanner means further comprises means for photoelectrically converting a scanned input data sheet.

4. A character reading apparatus for processing an input data sheet including character data, the character reading apparatus for use with a computer system including a display apparatus having a plurality of display areas including a default display area, the character reading apparatus comprising:

reading means for scanning the input data sheet, and for photoelectrically converting the scanned input data sheet;

image storing means for storing an output image data corresponding to the scanned input data sheet from the reading means;

character recognizing means for recognizing the output image data from the image storing means;

reject character detecting means for detecting a reject character and informing the character recognizing means not to recognize the reject character;

display control means for displaying the output image data from the character recognizing means, and for displaying in the default display area, the reject character from the reject character detecting means;

data modifying means for modifying the reject character; and

decision means for determining whether the displayed reject character overlaps the displayed output image data requiring the data modification, and wherein the display control means displays the reject character in a display area other than the default display area when the decision means determines that the displayed reject character overlaps the displayed output image data requiring the data modification.

5. The character reading apparatus according to claim 4, further comprising image disposing means for extracting a specific area from the output image data in the image storing means, the specific area being an area comprising a character to be extracted.

6. The character reading apparatus according to claim 4, further comprising image disposing means for extracting a specific area from the output image data from the image storing means, the specific area being an area including a work having a character to be extracted.
