Abstract
An image reading apparatus includes a first light source, a second light source, a visible imaging sensor, an invisible imaging sensor, and a reduction unit. The first light source irradiates an object with visible light. The second light source irradiates the object with invisible light. The visible imaging sensor reads a visible image of the object. The invisible imaging sensor reads an invisible image of the object. The reduction unit reduces a visible wavelength component of light received by the invisible imaging sensor.
