Claim One:
1. An image processing apparatus performing a character recognition process of characters written on a document, the character recognition process being performed based on image data obtained by reading the document, the image processing apparatus comprising: a character size determination section configured to determine to which one of size ranges a character size of the characters in the image data to be subjected to the character recognition process belongs, the size ranges including a standard size range not more than a predetermined size and a plurality of size ranges larger than the predetermined size; a reduction processing section configured to, in a case where the character size determination section determines that the character size of the characters to be subjected to the character recognition process in the image data belongs to one of the plurality of size ranges larger than the predetermined size, reduce a region at least including the characters determined as belonging to the size range larger than the predetermined size, so that the character size becomes not more than the predetermined size, the character size being reduced by use of a reduction ratio corresponding to the character size of the determined size range, each of the size ranges being set in advance with a reduction ratio used for reducing the character size of the characters belonging to the respective size range; and a recognition processing section configured to perform the character recognition process of the characters included in the image data, in the case where the character size determination section determines that the character size of the characters to be subjected to the character recognition process in the image data belongs to one of the plurality of size ranges larger than the predetermined size, the recognition processing section performing the character recognition process with use of the image data in which the region including the characters determined as belonging to one of the plurality of size ranges larger than the predetermined size is reduced by the reduction processing section.
