Abstract

Embodiments of the present invention provide a device and method for correcting a document image and a scanner. Wherein the device includes: an extracting unit configured to extract boundaries in a first direction of the document image and extract lines in the first direction according to a content of the document image, a filtering unit configured to filter the extracted lines, a constructing unit configured to extend and adjust the filtered lines and construct a correcting mesh, and a correcting unit configured to perform correcting according to the correcting mesh. An accurate correcting model can be constructed by taking document boundaries and document contents into account in constructing the correcting model and constructing a correcting mesh after filtering, extending and adjusting the extracted lines, thereby effectively eliminating distortion in the document image.
