Abstract
An image extraction system includes a connected pattern extracting part for extracting partial patterns respectively having connected pixels from an image which is formed by a block frame having a table format and including one-character frames or a free format frame, characters, graphics or symbols, a one-character frame extracting part for extracting one-character frames from the image based on the partial patterns extracted by the connected pattern extracting part, a straight line extracting part for extracting straight lines from the partial patterns which are extracted by the connected pattern extracting part and is eliminated of the one-character frames by the one-character frame extracting part, a frame detecting part for detecting straight lines forming the frame from the straight lines extracted by the straight line extracting part, and a frame separating part for separating the straight lines detected by the frame detecting part from the partial patterns so as to extract the characters, graphics or symbols.
