Problems solved by technology

[0007] However, when the character frame information is pre-registered by the operator as described above, usually, the operator needs to designate the character frame shape, character frame color, etc. There is a problem that the operator's workload increases
[0008] Also, when the character frame uses a faded color, there is a problem that the characters in the character frame that use a color other than the faded color cannot be recognized.

Abstract

The invention provides a character recognition device. The invention aims to provide a character recognition device that is capable of reducing the workload of an operator during character recognitionand does not limit the colors used by character frames. The analytic range specified by the operator in the color image data of a note is firstly classified into background, a character frame and a character, the character frame is highly precisely determined according to the classification result, and then the character frame is removed from the color image data from which the background is eliminated, and finally the character recognition is carried out on the residual character.

Description

technical field [0001] The invention relates to a character recognition device for recognizing characters in a character frame in a bill. Background technique [0002] Generally, a character recognition device reads handwritten characters or printed characters as color image data, and recognizes characters based on a result of collation between the color image data and character patterns registered in advance. [0003] When recognizing characters in a character frame in a bill in such a character recognition apparatus, after the character frame is determined, the determined character frame is removed from the color image data of the bill to recognize the remaining characters. [0004] Furthermore, when specifying a character frame, it is necessary for an operator to register character frame information (eg, character frame shape, character frame color, etc.) in advance (for example, refer to Patent Document 1). [0005] In addition, there is a character recognition device t...
