Abstract
In a character recognition method and apparatus, image information is input, the input image information is displayed, a desired area in the input image information is assigned, the number of characters contained in the assigned area is calculated, and the size of a picture frame for displaying a result of character recognition of the image information is determined according to the calculated number of characters.
Claims9
A character recognition method comprising the steps of:
- inputting an image of a document;
- displaying the input image;
- segmenting character patterns from the input image information;
- calculating the number of character patterns contained in a specified portion of the image marked by a cursor on a display picture which displays said input image based on the result of segmenting;
- determining the size of a display area required for displaying a result of character recognition of the specified portion of the image according to the calculated number;
- and
- performing a display control so as to change the size of an area required for displaying a result of character recognition of the specified portion of the image in accordance with a size determined in said determining step.

An image processing method comprising the steps of:
- segmenting character images from a document image;
- storing character positions corresponding to the segmented character images;
- displaying the document image and text comprised of character patterns obtained by recognizing the segmented character images;
- designating a position of a desired character pattern based on the text displayed in said displaying step;
- identifying a character image corresponding to the desired character pattern using the stored character positions;
- and
- performing a display control so as to change the display of the document image such that said identified character image is displayed so as to be discriminated from the other character images.
