A reading device includes an imaging element and correcting circuitry. The imaging element is configured to receive light from an object selectively irradiated with visible light or invisible light. The correcting circuitry is configured to apply correction processing based on a difference in an optical characteristic between an invisible light region and a visible light region to an image signal in the invisible light region output from the imaging element and output the image signal corrected.
