Abstract

Disclosed is an image processing apparatus which (i) determines whether or not characters to be subjected to a character recognition process in image data have a size larger than a predetermined size, (ii) in a case where the characters is determined as larger than the predetermined size, reduces at least a region including the characters so that the size of the characters fits within the predetermined size, and (iii) performs a character recognition process of the characters with use of the reduced image data.

Description

technical field [0001] The present invention relates to an image processing device and an image processing method for performing character recognition processing on characters written in a document based on document image data obtained by reading the document. Background technique [0002] In the prior art, there is a technique of reading information recorded on paper media with a scanner, creating image data, and performing character recognition (OCR (Optical Character Recognition) processing on characters contained in the image data. ), and create the text data. [0003] For example, Patent Document 1 discloses a technique of using a high-resolution photoelectric conversion device with a large number of pixels and a low-resolution photoelectric conversion device with a small number of pixels in order to read small characters with high precision and read large characters at high speed. High-resolution photoelectric conversion equipment to read images, in the case of small ...
