A paper-sheet recognition apparatus that acquires information from a paper sheet and recognizes the paper sheet based on the information. The apparatus includes one or more light emitting units that output first to n-th lights (n&#x2267;2) of different wavelengths; an emission controller that performs emission control of the light emitting units; a light receiving unit that receive a component of a light, which has been emitted from the light emitting unit and then reflected from and/or transmitted through the paper sheet; and a paper-sheet recognition processor that recognizes the paper sheet by using an optical signal received by the light receiving unit. The emission controller performs the emission control of the light emitting units such that the number of light emissions per one emission cycle with respect each of to the first to n-th lights differs depending on information desired to be used in recognizing the paper sheet.

Paper-sheet recognition apparatus, paper-sheet processing apparatus, and paper-sheet recognition method

To provide a paper sheet discriminating apparatus and method capable of discriminating even a paper sheet such as a US dollar bill, in which the location of a pattern is dislocated from the periphery due to a printing shear or a cutting dislocation, efficiently without any drop of the discrimination percentage by using the image of the paper sheet. A paper sheet discriminating apparatus for deciding at least the kind of a paper sheet on the basis of its pattern by sampling the image of its whole surface. The dislocation of the pattern, as viewed from the contour, is detected on the basis of the marginal length of the paper sheet from the outer periphery to the pattern, thereby to correct a pixel position for providing a base point for the image recognition of the paper sheet, with the detected dislocation. Moreover, the difference of the marginal lengths is determined at the portion, where the channels at the identical position in the transfer direction and the lines in the transfer transverse direction are identical, to prevent an excessive correction by substituting a predetermined maximum when the difference is not less than a predetermined value, and to determine an average value by excluding the maximum and the minimum of the marginal lengths of a plurality of portions of each side.
