ABSTRACT:
An apparatus for separating an image from a black frame quickly and precisely wherein corner coordinates for a character field are inferred by using a parameter relative to a character frame layout, and more precise corner coordinates are detected by pel distribution in a partial range. The positions of inner walls of a black frame are then inferred by using the detected corner coordinates and the parameter relative to the character frame, and a detection area is set. The positions of the inner walls are precisely detected by the pel distribution in the detection area, and smoothing process is performed on the detected values by employing the detected values of other adjacent black frames. Sequentially, white lines are drawn along the inner walls to separate the black frame from the character, and noise is removed. In consonance with a skew value, the detection area is divided to change the set range, and data separation is performed by using two white lines with a step difference between them. Through this processing, even when a skew value is large, the position of a black frame can be precisely determined, and since scanning is performed only in a partial range, fast processing can be provided.
