In a preferred embodiment, the radiation sources are light emitting diodes (LEDs).Each type of radiation source (for example, UV light, IR light, and such like) may comprise a plurality of source elements.It is among the objects of one or more embodiments of the present invention to obviate or mitigate the above disadvantages or other disadvantages associated with prior art media validating modules.According to a first aspect of the present invention there is provided a module for validating deposited media items, the module comprising: illuminating means for illuminating a deposited media item with ultra-violet radiation, infra-red radiation, and discrete primary colours; directing means for directing illuminations from the illuminating means to an examination area; optical detecting means for detecting emissions from the deposited media item at the examination area, where the emissions are caused by the illuminations; and processing means for processing the detected emissions; wherein the processing means is operable in either a first mode, in which the deposited media type is known, or in a second mode, in which the deposited media type is not known.The three primary colour sources may be activated sequentially so that one colour source is activated at a time, for example, a red source may be activated, then a green source, then a blue source; alternatively, the three colour sources may be activated simultaneously (that is, the sources may be activated as if the three primary colour sources were a single source of white light) so that white light is produced.According to a third aspect of the present invention there is provided a method of validating deposited media items, the method comprising the steps of: receiving a media item to be validated; ascertaining if the media item is of a known type; if the media item is of a known type, applying a media-specific illumination scheme to the media item, where the media-specific illumination scheme activates only those illumination sources required for validating that media type; if the media item is not of a known type, applying a non-media-specific illumination scheme to the media item; detecting emissions from the media item, where the emissions are caused by the activated illumination sources; collating the detected emissions according to the type of source used; and processing the collated emissions to validate the media item.
In a preferred embodiment, a CIS module is used so that the module is relatively small in size and can be located in close proximity to a media item in the examination area.
Preferably, the examination area extends across an entire width of a deposited media item, so that the entire width of each deposited media item is illuminated.
The directing means may be implemented by focusing optics.
Alternatively, the directing means may be implemented by a housing for maintaining the illuminating means in a pre-determined configuration so that the illuminating means are permanently directed to the examination area.
Where focusing optics are used, the optics may be provided by one or more lenses, and/or prisms, and/or mirrors, and/or light guides.
The module comprises: illuminating means (24) for illuminating a deposited media item (20); directing means (34) for directing illuminations from the illuminating means (24) to an examination area (22); optical detecting means (26) for detecting emissions from the deposited media item (20) at the examination area (22), where the emissions are caused by the illuminations; and processing means (32) for processing the detected emissions.
