Description

technical field

[0001] The invention relates to an optical character reading device (OCR: Optical Character Reader), a scanner, a digital camera, etc. to photograph documents such as accounts, and extract images of specific objects such as characters, imprints, marks, etc. from the generated document images. A processing method and an image processing device. Background technique

[0002] In financial institutions and local governments, scanner devices such as OCR are used to improve the efficiency of document processing operations such as forms. The main functions of OCR are the generation of document images, the extraction of text in document images, and the recognition of text. The types of document images to be generated include binary images, luminance images, and color images.

[0003] Processing using binary images reduces the processing time due to the small amount of data. However, in binary image processing, there is a large overlap between ruled lines, bit line...
