摘要

Method and apparatus for the characterization and discrimination of legal tender bank notes and documents, by means of colorimetric analysis of the surface of them by illumination of the documents and analysis of the colour by means of at least one red-green-blue colour sensor. The signals obtained are conditioned in analog terms via means (9) and (10) and subsequently digitalized, with the aim of allowing their processing by microprocessor (11) and subsequent comparison with representative standards for valid documents.
