    摘要： A spectral color sensor including a spectroscopic unit that disperses reflected light from a measurement target, and a light detection element that detects the dispersed light from the reflected light, comprises: a storage unit that stores a correspondence relationship between a pre-measured wavelength of the dispersed light projected on the light detection element and a projection position, as well as a stray light component; a first correction unit that, based on a measurement result when a color is measured, corrects the correspondence relationship between the wavelength of the dispersed light projected on the light detection element and the projection position stored in the storage unit; and a second correction unit that carry out wavelength correction on the stray light component stored in the storage unit using the corrected correspondence relationship between the wavelength and the projection position.
