Classification: CPC G | IPC G

Claim 4:
5. A non-transitory storage medium storing an optical inspection program, the optical inspection program causing a computer to implement:
by using an optical apparatus configured to emit a light beam having a first wavelength and a light beam having a second wavelength different from the first wavelength in a single direction toward an imaging unit in accordance with a light beam direction from a subject, with a light beam intensity of the first wavelength and a light beam intensity of the second wavelength being in a complementary relationship, acquiring image data including information of a first image related to the first wavelength and information of a second image related to the light beam having the second wavelength with the imaging unit,
separating the image data into the information of the first image and the information of the second image,
comparing the information of the first image and the information of the second image, and
extracting unevenness information of the subject,
wherein the complementary relationship is a relationship in a certain pixel of the imaging unit, in which:
when the light beam intensity of the first wavelength is increased, the light beam intensity of the second wavelength is weakened in the same certain pixel, or
when the light beam intensity of the second wavelength is increased, the light beam intensity of the first wavelength is weakened in the same certain pixel.
