Abstract
A communication system includes a transmission terminal for displaying a color code having a plurality of colors of code patterns arranged two-dimensionally, and a spectroscopic measurement device including a variable wavelength interference filter for dispersing the light from the image displayed on the transmission terminal, an imaging section adapted to image the light dispersed by the variable wavelength interference filter to obtain a spectral image, a colorimetric section adapted to measure a dispersion spectrum of each of pixels in each of spectral images of a plurality of wavelengths with respect to the color code based on the light intensity value in each of the pixels, in the case in which the spectral images are obtained, and a decode section adapted to detect an arrangement of the code patterns based on the pixel positions and the dispersion spectrums of the respective pixels, and decode the color code.
