Definitions

  • the reference spectral reflectance is acquired by measuring the patch image with the reference machine of the spectroscopic measuring machine, and the patch image is created by the spectroscopic measuring machine which is the correction target machine. By doing so, the spectral reflectance to be corrected is acquired. Then, a correction coefficient is generated for each wavelength based on the reference spectral reflectance, and the correction target spectral reflectance is corrected for each wavelength by the above correction coefficient. As a result, the measurement result of the spectral reflectance by the correction target machine can be corrected with high accuracy based on the difference in the spectral sensitivity between the models.
  • the image signal value obtained from the image obtained by taking the color chart is the image of the actual object. It may be different from the signal value. That is, even if the image signal value is obtained by photographing the color chart as a substitute for the object, there is a possibility that the signal value does not correctly reproduce the image signal value of the object.
  • the approximation step it is more preferable to approximate the acquired spectral characteristics of the object by an approximation formula expressed by a linear sum of the same number of terms as a plurality of color charts. .. With the above configuration, it is possible to more easily estimate the image signal value when the object is photographed by the photographing apparatus.
  • the image signal value when the object is photographed by the photographing apparatus is accurately obtained by using the image signal value of each of the plurality of color charts, and depends on the spectral sensitivity of the photographing apparatus. Can be estimated without.
  • the object S contains a specific coloring material and is arranged in a measurement environment to be applied with external energy under the environment, so that the amount of external energy can be reduced. It is a sheet body that develops color accordingly.
  • the "specific color material” is, for example, a color material composed of a color former and a color developer microencapsulated in a support, and specifically, is described in Japanese Patent Application Laid-Open No. 2020-073907. It is composed of a color former and a color developer.
