    摘要: An apparatus and method of converting an image on a transparency such as photographic film to line art on a recording medium so that the line art may be microfilmed. The invention, through the use of optical processing techniques, greatly simplifies the conversion of continuous tone and half tone photographs to line art which heretofore had to be manually traced prior to microfilming the line art.
