Claim 6:
7. The eye detecting method according to claim 1, further comprising:
generating, by the processor, a first image in which a pixel having a gradation value smaller than a threshold is represented at a first luminance value and a pixel having a gradation value not smaller than the threshold is represented at a second luminance value, after the grayscale image is binarized;
generating, by the processor, a second image by replacing a pixel which has the second luminance value in a first luminance region having the first luminance value in the first image and satisfies a predetermined condition with a pixel having the first luminance value;
calculating, by the processor, iris information including information indicative of at least one of a position of an iris of the person or a size of the iris of the person using the second image; and
outputting, by the processor, the iris information.
