  • Patent number: 8842344
    Abstract: An illumination device includes a light guide made of plastic, and a light source including a light emitting element whose dominant wavelength is a light emission wavelength in an infrared region, and identifies a banknote. White reference plates are provided at positions that are at opposite ends of a rod lens array and cover respective areas external to an image region across the banknote. A correction coefficient is acquired by calculation. The calculation is made by correcting an illuminance such that IR correction data is substantially identical to IR reference data preliminarily stored in a memory circuit in a signal processor on the basis of IR white reference data representing a white reference illuminance generated from light reflected from the white reference plates. The correction coefficient is used for correcting IR image data when the banknote is read.

  • Patent number: 8498030
    Abstract: An image sensor using three-color, e.g., R, G, and B light-emitting elements assures a period in which all the three colors are turned on and periods in each of which one light-emitting element is turned off during a scan period per pixel, and integrates and measures amounts of light of the respective periods. An amount of light based on the OFF light-emitting element is calculated based on a difference between the amounts of light during the full light-ON period and each light-OFF period to define an amount of light of the light-emitting element, and light intensity information corresponding to each light-emitting element is obtained based on a total amount of light during the entire scan period per pixel, and the amount of light of each light-emitting element.
