1. A device comprising:
a light source configured to project a dot pattern created by a first light onto a skin of at least one user;
an image sensor configured to detect a second light resulting from the projection of the dot pattern and generate image data which indicates an image of the skin onto which the dot pattern is projected; and
an arithmetic circuit, wherein:
the second light includes a component corresponding to light which is scattered inside of the skin, and
the arithmetic circuit:
estimates a dispersion degree of intensity of the component corresponding to the light which is scattered inside of the skin based on the image data, and
generates skin age data that indicates a skin age based on the dispersion degree, the skin age indicating younger age as the dispersion degree increases.
