To faithfully reproduce the original color of an object even under various kinds of environment.
This spectroscopic image photographing equipment is provided with a first optical system 2 which acquires a spectroscopic image of only a visible region consisting of three primary colors of the object, a second optical system 3 which acquires a spectroscopic image of only a near-infrared region of the object, a third optical system 4 which acquires intensity of incident light from a direction different from that of the object at the time of acquisition of the spectroscopic image and an image conversion means 6 which divides pixel values of each spectroscopic image acquired by the first and second optical systems 2, 3 by a pixel value corresponding to wavelength to be acquired by the third optical system and converts them into a relative spectral reflectance image.
