  • Method and apparatus for document digitization
    Patent number: 8902481
    Abstract: In a method for document digitization, an apparatus generates a first image of a document sheet by irradiating the document sheet using a first light source and detecting the document sheet irradiated with light from the first light source, which enables detection of ink on the document sheet that defines a marked portion. The apparatus further generates a second image of the document sheet by irradiating the document sheet using a second light source and detecting the document sheet irradiated with light from the second light source, which enables detection of content on the document sheet. The apparatus further obtains a region of the second image that corresponds to the marked portion of the document sheet based on the first image.
