Abstract
A method for detecting character string regions in a document image containing figures and illustrations includes storing image data of the document, generating position data of a run of black pixels in each line by accessing the stored image data, comparing runs of black pixels for each pair of two adjoining lines and determining whether a run is a boundary candidate, and generating a rectangle whose boundaries include at least a pair of boundary candidates determined to be a character string region.
