摘要： An image sensor for detecting a counterfeit bill includes an ultraviolet ray emitting section for emitting ultraviolet rays to a bill to be checked; an image sensor section for acquiring a first image as an image obtained by photographing the bill to be checked in a state in which ultraviolet rays are not emitted by turning off the ultraviolet ray emitting section, and a second image as an image obtained by photographing the bill to be checked in a state in which ultraviolet rays are emitted by turning on the ultraviolet ray emitting section; a storing section for storing the first image and the second image; and a counterfeit bill detecting section for extracting a fluorescent image by removing the first image from the second image stored in the storing section and determining whether the bill to be checked is a counterfeit bill or an original bill.
