Abstract: A lighting device includes a base unit arranged on a medium installation face on which a medium is disposed, an arm unit extending upwardly from the base unit, a top unit extending from the arm unit so as to face the medium installation face, a mounting face disposed on the top unit to mount an image capturing unit at a position capable of photographing the medium on the medium installation face, a lighting disposed in the top unit to irradiate the medium installation face, and a lighting control unit configured to adjust an amount of light of the lighting. The lighting control unit sets the amount of light of the lighting to a maximum at the time of photographing and, after the photographing, returns the amount of light to that before the photographing.
