<p>PURPOSE: To relieve the burden of work by automatically obtaining the variable power rate and rotation angle of a photographic original. CONSTITUTION: A layout designation paper sheet 11 is read, and a parameter detection means 20 detects a height of an original frame and a tilt with respect to an horizontal line on layout image data, and an edge detection means 30 obtains a height of an object image and a tilt of the edge with respect to a tentative horizontal line based on original image data obtained by reading a photographic original 13, and a magnification angle arithmetic section 40 multiplies a rough magnification with a ratio of a height of the original frame to a height of the object image to obtain the variable power rate. Furthermore, the tilt of the object image is matched with the tilt of the original frame to obtain a rotary angle.</p> |
