1. An information detecting device comprising:

  • a memory that stores video information obtained by photographing an object that reflects light in which embedded information is superimposed onto a plurality of components in a color space;

    a processor that detects the embedded information from an emphasized signal obtained from an image included in the video information by emphasizing a first color component more than a second color component according to a spectral reflection characteristic of a surface of the object, the first color component and the second color component being from among a plurality of color components that correspond to a plurality of wavelengths, the first color component having a reflectance higher than a reflectance of the second color component in the spectral reflection characteristic; and

    a display device that outputs information on the basis of the embedded information detected by the processor.
