摘要：
A reading device includes a first light source configured to emit light, a second light source configured to emit light in a wavelength of light different from a wavelength of light of the first light source, circuitry configured to instruct the first light source and the second light source to turn on and turn off, a first light-intensity adjuster configured to adjust light intensity of the first light source based on a first light intensity value, a second light-intensity adjuster configured to adjust light intensity of the second light source based on a second light intensity value, a first image sensor configured to receive the light that is emitted from the first light source and is reflected by an object, and a second image sensor configured to receive the light that is emitted from the first light source and the second light source and is reflected by the object.
