, only the box rectangle can be extracted, thereby distinguishing the box rectangle from the enclosing rectangle for the headline characters. As a result, only the headline characters can be extracted with high precision.
A further aspect of the present invention includes a projection unit for projecting the rectangle number assigned to the enclosing rectangle to the coordinates set on the input image. The box rectangle extraction unit extracts the first enclosing rectangle by searching the range of the coordinates of the second enclosing rectangle for the rectangle number contained in the coordinates.
Thus, an enclosing rectangle existing in another enclosing rectangle can be easily extracted. As a result, even if a box rectangle enclosing text characters and headline characters coexist, only the box rectangle can be quickly extracted.
A further aspect of the present invention includes a connected element extraction unit for extracting the connected elements of an input image; an enclosing rectangle generation unit for generating an enclosing rectangle of the connected elements; an overlap level evaluation unit for computing the number of enclosing rectangles overlapping the enclosing rectangle; and an overlapping nest integration unit for performing an overlapping nest integrating process.
Thus, the overlapping nest integrating process is performed only on the enclosing rectangles having a high overlap level, and the process can be omitted on enclosing rectangles having a low overlap level. As a result, an enclosing rectangle of headline characters can be prevented from being lost by enclosing rectangles being integrated on the entire screen, and a part of a drawing or a photograph having a high overlap level can be absorbed or integrated into a larger rectangle. Thus, it can be avoided that an enclosing rectangle of a part of a drawing or a photograph remains as is to be mistakenly extracted as headline characters or mistakenly integrated into a rectangle as headline characters. As a result, headline characters can be extracted with high precision even if the headline characters coexist with a drawing, a photograph, etc.
A further aspect of the present invention includes a projection unit for projecting the rectangle number assigned to the enclosing rectangle to the coordinates set on the input image; and an overlapping rectangle extraction unit for extracting an enclosing rectangle overlapping a predetermined enclosing rectangle by searching the range of the coordinates of the predetermined enclosing rectangle for a rectangle number contained in the coordinates.
Thus, enclosing rectangles overlapping each other can be easily extracted, thereby quickly computing the overlap level of the enclosing rectangles. 1. Field of the Invention

, only the box rectangle can be extracted, thereby distinguishing the corner rectangle from the enclose rectangle for the headline characters. As a result, merely the headline quality can be extracted with high preciseness. 
 A further aspect of the present invention includes a projection unit of measurement for projecting the rectangle number assign to the enclosing rectangle to the coordinates fructify on the stimulation image. The box rectangle extraction unit extracts the inaugural enclosing rectangle by searching the range of the coordinate of the second enclosing rectangle for the rectangle number contain in the coordinates. 
 therefore, an enclosing rectangle exist in another enclosing rectangle can be easily extracted. As a resultant role, even if a box rectangle enclosing text characters and headline characters coexist, only the box rectangle can be quickly extracted. 
 A further aspect of the present invention includes a connected element extraction unit for extracting the connected component of an input image; an insert rectangle coevals unit for generating an enclosing rectangle of the affiliated elements; an overlap level evaluation unit for calculate the number of enclosing rectangles overlapping the enclosing rectangle; and an overlapping nest integration unit for performing an overlapping nest integrating process. 
 therefore, the overlapping nest integrate procedure is performed only on the enclosing rectangles have a high overlap level, and the procedure can be omitted on enclosing rectangles having a broken overlap degree. As a result, an enclosing rectangle of headline character can be prevented from being fall back by enclosing rectangle being integrated on the entire sieve, and a part of a drawing or a photograph have a high lap level can be absorbed or integrated into a large rectangle. Thus, it can be avoided that an enclosing rectangle of a part of a drawing or a photograph remains as is to be mistakenly extract as headline characters or mistakenly integrated into a rectangle as headline fictional character. As a result, headline characters can be extracted with high precision even if the headline characters coexist with a draft, a photograph, etc. 
 A further aspect of the present invention includes a projection unit for projecting the rectangle number delegate to the enclose rectangle to the coordinate fix on the input image; and an overlapping rectangle extraction unit for extract an enclosing rectangle overlapping a predetermined insert rectangle by searching the range of the coordinates of the predetermined enclosing rectangle for a rectangle issue contained in the coordinates. 
 Thus, insert rectangles overlapping each early can be easily extracted, thereby quickly computing the overlap level of the enclosing rectangles. 1. Field of the Invention
