QUALIFICATION SYSTEM FOR PRINTED IMAGES |
摘要 |
A system for automatically determining the quality of various types of printed images uses either a single element optical sensor or a multi-element sensor which may include one or more of an optical, magnetic, thermal or acoustic transducer (1, 1x). A microprocessor (9, 10) is used to store a standard set of images in its memory and automatically compares the printed images on a background material with the standard images. The microprocessor then causes the system to produce a result of said comparison. The system has various uses but is particularly useful in the banking business to process cheques. |
