The apparatus for reading spectral information out of image patterns includes a solid-state image sensor for taking pictures of image patterns, a unit for making one-dimensional images out of lights having reflected at the image patterns, a spectroscope introducing the one-dimensional images into the solid-state image sensor, a shutter unit located in front of the solid-state image sensor, and a synchronizer turning the shutter unit on or off in synchronization with movement of the image patterns, the spectroscope disperses lights 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. |
