ABSTRACT:
A method and an apparatus for isolating an area corresponding to a character or word in an optical character recognition device. Original manuscript images are compressed (reduced) in a scanning direction corresponding to the direction of the original manuscript image's line (column), and areas where the black picture elements correpsonding to the compressed original manuscript images are connected with each other are searched by following the contour of the areas of connected black picture elements contained in the compressed images. Then, a minimum coordinate point and a maximum coordinate point are obtained in accordance with the areas determined by searching, and rectangular areas determined by the minimum coordinate point and the maximum coordinate point of the area where the black picture elements are connected with each other are extracted. Finally, each area of the original manuscript images corresponding to the extracted rectangular areas is isolated as an area of image.
