The apparatus (500) for reading spectral information out of image patterns includes a solid-state image sensor (510) for taking pictures of image patterns (115), a unit (520) for making one-dimensional images out of light having reflected at the image patterns, a spectroscope (530) introducing the one-dimensional images into the solid-state image sensor (510), a shutter unit (511) located in front of the solid-state image sensor (510), and a synchronizer (540) turning the shutter unit (511) on or off in synchronization with movement of the image patterns, the spectroscope (530) disperses light having entered thereinto into each of wavelengths, and makes three-dimensional image spectrum which is wavelength dispersive for each of pixels in association with each of locations of the image patterns.
