Abstract
A controller of an image reading device performs search for an edge candidate position inward from an edge portion in a main scanning direction of analysis image data in an extraction process of extracting a document region from read image data. When the retrieved edge candidate position corresponds to a dirt position, the search is continued whereas when the retrieved edge candidate position does not correspond to the dirt position, the document region is extracted from the read image data at the retrieved edge candidate position.
