Abstract
A memory 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 emphasizes a signal obtained from an image included in the video information on the basis of a result of emphasizing a first color component more than a second color component according to a spectral reflection characteristic in a range including the object, and detects the embedded information from the emphasized signal, 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. A display device outputs information on the basis of the embedded information detected by the processor.
