定したことを特徴とする色識別装置。 The optical image of the object to be inspected, in which the wavelength of the color to be identified changes from the short wavelength side λA to the long wavelength side λB, is separated into multiple color systems in the color separation section, and the separated optical signals are separated into each color. In a color identification device, a signal processing unit for each system performs photoelectric conversion into a digital signal, and a color calculation unit identifies the color based on the digital signal for each system. The system is separated into two systems, the short wavelength λA and the long wavelength λB.
A color identification device characterized in that an optical filter and an illuminator are selected so that >λB.
