Spectrometry method and spectrometry apparatus

A spectrometry method used with a spectrometry apparatus including

• a spectrometry section including a spectrometer that spectrally separates reflected light reflected off an imaging target to select light having a predetermined wavelength and an imaging device that captures a spectroscopic image based on light fluxes having a plurality of wavelengths selected by the spectrometer,
• a spectroscopic controller that controls an action of the spectrometer,
• a spectroscopic image generator that generates the spectroscopic image, and
• a display section that displays a teaching-purpose visualized image that is an image that visualizes the imaging target,
• the method comprising:
• a teaching-purpose spectroscopic image generation step of generating a teaching-purpose spectroscopic image as the spectroscopic image;
• a teaching-purpose visualized image generation step of generating the teaching-purpose visualized image and causing the display section to display the generated teaching-purpose visualized image;
• a first teaching-purpose spectrum generation step of identifying a first teaching area in the teaching-purpose visualized image and generating a first teaching-purpose spectrum that is an optical spectrum of the first teaching area from the teaching-purpose spectroscopic image;
• a first icon display step of calculating a first display color based on a display color of the first teaching area of the teaching-purpose visualized image and causing the display section to display a first icon showing the first display color;
• a first chromaticity teaching step of accepting input of first teacher data that teaches chromaticity of the first teaching area in a position in the display section that is a position corresponding to the first icon;
• a conversion rule generation step of generating a conversion rule based on a relationship between the first teaching-purpose spectrum and the first teacher data;
• a measurement-purpose spectroscopic image generation step of generating a measurement-purpose spectroscopic image as the spectroscopic image;
• a measurement-purpose spectrum generation step of generating from the measurement-purpose spectroscopic image a measurement-purpose spectrum that is an optical spectrum;
• and
• a chromaticity calculation step of calculating chromaticity from the measurement-purpose spectrum based on the conversion rule.
