Abstract
PURPOSE: Loop pick up system which can surely pick up the loop such as character with a simple processing.
CONSTITUTION: The scanning information for one line's share at n-1th line and n-th line are written in the registers 1, 2 respectively. When the bits of the register 1 are all black or white bit information and the white bit information clipped with the black bit information is present in the register 2, or the contrary, the start or end signal is outputted from the start and end signal production circuit 3. The branch discovery gate 4 discovers the branch with present scanning information and that before one scanning. Every time when the branch is discovered, it is counted in the counter 8. Every time when the start point or the branch point corresponding to the start point is detected, the content is made by +1 to the pair number counter 9. It is judged as the presence of loop that the pair having the same branch number is taken as a set and when outside of the start and end point of the said set is all black.
