CPC G06V 40/18 (2022.01) [G06F 21/32 (2013.01); G06V 10/143 (2022.01); G06V 10/56 (2022.01); G06V 40/19 (2022.01); G06V 40/193 (2022.01); G06V 40/40 (2022.01)] | 7 Claims |
1. An authentication system comprising:
a capture device configured to capture an iris used for authentication of a person using a first wavelength band and a second wavelength band;
an authentication device configured to authenticate the person using a determination result of presence or absence of a color contact lens on the iris;
an information processing device configured to execute processing based on an authentication result of the authentication device; and
an image processing device including:
a memory; and
at least one processor coupled to the memory,
the at least one processor performing operations to:
calculate a first feature amount in the first wavelength band using an image in the first wavelength band,
calculate a second feature amount in the second wavelength band using an image in the second wavelength band, and
determine presence or absence of the color contact lens on the iris based on the first feature amount and the second feature amount, wherein
the capture device includes:
a transmitted light change element that changes a wavelength band of light transmitted based on a control signal; and
a capture element that outputs an image based on the transmitted light of the transmitted light change element.
