A paper-sheet recognition apparatus includes a paper-sheet information acquisition unit that acquires paper-sheet information including an image data of the paper sheet; a candidate narrowing-down unit that narrows down a number of type candidates of the paper sheet to a small number of types based on the image data included in the paper-sheet information; a type determining unit that determines one type from the type candidates narrowed down by the candidate narrowing-down unit based on the image data included in the paper-sheet information; authenticity recognition unit that recognizes authenticity of the paper sheet as to each type candidate narrowed down by the candidate narrowing-down unit; an execution instructing unit that issues an instruction such that the type determining unit and the authenticity recognition unit are operated concurrently; and a final judgment unit that performs a final judgment on the paper sheet by combining the type determined by the type determining unit and authenticity recognition result corresponding to the type from among authenticity recognition results of the candidate types recognized by the authenticity recognition unit.

Paper sheet recognition device and paper sheet recognition method

In an authenticity determining apparatus, an image-data acquiring unit acquires image data of a paper sheet; a block-value calculating unit divides the image data into a plurality of blocks each composed of a plurality of pixels and calculates a block value of each of blocks; an average-block-value calculating unit calculates an average block value of blocks composing a predetermined area of the image data; a correction-block-value calculating unit calculates a corrected block value of each of the blocks by correcting each of the block values so that the average block value is equal to a predetermined reference value; and an authenticity determining unit that determines authenticity of the paper sheet based on whether each of corrected block values of the blocks composing the predetermined area is within a predetermined allowable numerical range that is preliminarily defined for the predetermined area.
