Abstract
A marked region recognition apparatus recognizes an arbitrary marked region of a document image from a mark signal which indicates whether or not there exists a mark which indicates the marked region. The marked region recognition apparatus comprises a first storing part for storing the mark signal for at least one scanning line, a second storing part for storing a coordinate in a main scanning direction where the marked region ends for each scanning line based on the mark signal stored in the first storing part, and a recognition part for recognizing an inside and an outside of the marked region and producing a marked region signal which indicates the inside or the outside of the marked region for a present scanning line responsive to a state of the marked region of a previous scanning line, which state is read out from the first and second storing parts.
