Abstract
A method including correcting output of an image sensor unit based on correction information of the image sensor unit that captures and discriminates a paper sheet. A apparatus includes an image sensor unit which includes an image capturing element that captures a banknote so as to discriminate the banknote, a controller that controls the image sensor unit, and a first attachment part, to which the image sensor unit is attached to be detachable, and which includes a connection terminal that connects the image sensor unit and the controller with each other, and which is arranged in a conveyance path for conveying the banknote.
Claims2
A correction method of a paper sheet handling apparatus, the method comprising:
- correcting an output of an image sensor unit, from among image sensor units, based on correction information stored in a storage element of the image sensor unit that captures and discriminates a paper sheet, wherein
- the correcting includes
- a black correction indicating an offset correction performed during a non-lighting period of a light source of the image sensor unit, and
- a white correction indicating an output correction of each of image capturing elements, which is performed by using a reference output correcting medium corresponding to the paper sheet, during a lighting period of the light source of the image sensor unit, and
- a shading correction for making outputs of the image capturing elements even,
- wherein
- the shading correction is included in the white correction, as part of the white correction, and
- when a maintenance or replacement is performed on the image sensor unit, the maintenance or replacement is performed in units of a pair of image sensor units of the image sensor units, on which the black correction and the white correction are performed on shipping.
