An embodiment of an image reading device may include a light source, an image reading unit, a drive control unit, a white reference member, a chromaticity detecting unit, a reference value storage unit, a chromaticity change calculating unit, and/or a control unit. An embodiment may include a photoelectric conversion element that reads an image illuminated by the light source. In some embodiments, may measure the chromaticity of a white reference member. In some embodiments, a reference value storage unit may store a reference value representing the chromaticity of an image. In an embodiment, a control unit may control an operation of the device according to the calculated amount of chromaticity change. An embodiment may include measuring the luminous intensity of a light source and storing a reference value representing the luminous intensity of the light source. Some embodiments may include making adjustments to images.
