Abstract
To make it possible to cut out an image area corresponding to a document with a high accuracy from an image obtained by scanning a document without forcing a user to perform complicated work or without giving a feeling of discomfort at the time of performing multi-crop processing. To this end, first, position information on the document is acquired by detecting an edge component from a first image obtained by setting high the first white reference value. Then, an image area corresponding to the document is cut out based on the acquired position information from a second image obtained by setting the second white reference value lower than the first white reference value.
