Abstract
An image processing apparatus including: an analysis unit configured to extract a text area by performing area division processing for a binary image obtained by binarizing the scanned image by a first binarization method; a determination unit configured to determine a binary image used in OCR processing; and a character recognition unit configured to perform the OCR processing by using the binary image determined by the determination unit for the text area extracted by the analysis unit, and the determination unit: in a case where a binary image used in the area division processing is suitable to the OCR processing, determines the binary image as a binary image used in the OCR processing; and in a case where a binary image used in the area division processing is not suitable to the OCR processing, generates a binary image by a second binarization method whose accuracy is higher than that of the first binarization method and determines the generated binary image as a binary image used in the OCR processing.
