摘要：
An image processing apparatus includes a presumed background region extractor for extracting a presumed background region presumed to include an image of a background from an input image, a threshold value determination module for determining a threshold value based on pixels in the presumed background region, an edge pixel extractor for using the threshold value to extract edge pixels from the input image, and a document region detector for detecting a document region from the edge pixels.
