Abstract

PURPOSE:To recognize a data large in capacity in a short time by a small number of memories by providing a means for separating a character in a large screen and an isolated simbol from compressed image information, and recognizing them. CONSTITUTION:An image encoding means 3 inputs image information stored by an image storage means 2, and encodes an image data as length of a run of a black picture element. A graphic information separating means 5 inputs an encoded data stored by an encoded image storage means 4, and fetches a connected area being blow some size, as graphic information which goes to a candidate of a character or an isolated symbol. A graphic information recognizing means 7 inputs an encoded data stored by a graphic information storage means 6, and recognizes whether it is an isolated symbol or not at each connected area unit. A character recognizing means 9 recognizes whether that which is not recognized at the isolated symbol, in the encoded data stored by the graphic information storage means 6 is a character or not.
