Spectral reflectance interpolation method, color conversion profile generation method, and color conversion profile generation device

摘要

PROBLEM TO BE SOLVED: To optimize the interpolation of spectral reflectance. A spectral reflectance interpolation method for interpolating a spectral reflectance for each wavelength at a predetermined interval using a Bezier curve, wherein a smooth connection between the Bezier curves for each wavelength section having the predetermined interval as an interval width is provided. Including a variable acceptance step of accepting an input of a variable indicating the degree of control, a control point calculation step of calculating a control point in the wavelength section for each wavelength section based on the variable, the control point and the control point An interpolation value calculation step of calculating an interpolation value of the spectral reflectance by using the Bezier curve for each wavelength section based on the spectral reflectance corresponding to the end point of the wavelength section.
