Abstract
An information extraction device includes a storage unit, an image reading device and a control unit. Based on the color of a colored region in a reference original document (reference image data), the control unit classifies the colored region into a first colored region and a second colored region. The storage unit stores feature image data including the first colored region and position data indicating a distance and a direction from the feature image data to the second colored region. The control unit determines an extraction region based on the position of a region matching with the feature image data in comparative image data and the position data. The control unit stores, in the storage unit, extraction information extracted from the extraction region.
