Problems solved by technology

[0004] [4] However, when the focus of the business card image is not adjusted accurately or the business card image is not placed correctly, the recognition rate is lowered
[0006] [6] However, when there is a considerable number of characters on the image captured by the camera or scanner, since mobile phones have limited processing and memory resources, a considerable processing time is required even when the recognition process is optimized
Also, when the characters are composed of multiple languages, the recognition rate becomes worse compared to when they are composed of one language

Abstract

A document image processing apparatus includes an image capturing unit for capturing an image of a document, a detecting unit for detecting focusing and twisting states of the capture image, a display unit for displaying the detected focusing and twisting states, a character recognition unit for recognizing characters written on the capture image, and a storing unit for storing the recognized characters by fields.

Description

technical field [0001] [1] The present invention relates to a method and apparatus for recognizing characters on a document image captured by a camera and storing the recognized characters. In particular, the present invention relates to a method for recognizing characters on a business card image captured by a mobile camera phone having a built-in or external camera, and automatically storing the recognized characters in corresponding fields of a predetermined table such as a telephone directory database Methods and Apparatus. Background technique [0002] [2] Optical character recognition (OCR) systems or scanner-based character recognition systems are widely used to recognize characters on document images. However, since these systems are dedicated systems for recognizing characters on document images, a large amount of application software and hardware resources are required to process and recognize document images. Therefore, it is difficult to simply apply a characte...
