Abstract: A method for deriving a calculation equation for accurately calculating an irregularity of a coating film by using data on the surface of the object coating film and a color value of the coating film and a method for digitizing a coating film irregularity by using the coating film irregularity calculation equation derived from the deriving method. The coating film irregularity calculation equation is derived by fabricating a coated sheet for deriving the calculation equation and evaluating the coating (S10), calculating a value in substitution for the degree of sparkle (S11), measuring a color value (S12), and deriving the calculation equation (S13). The calculation (S11) of the value in substitution for the degree of sparkle includes image capture (S11a1) and image processing (S11a2). The measurement (S12) of the color value includes colorimetry (S121) and calculation (S122) of color values.

Abstract: At first, a sample for obtaining light measurement data is set to obtain reflectances. After setting an arbitrary wavelength λ i , a principal component analysis is executed to obtain an eigenvalue 1 and an eigenvector b. Then a basic equation for reflectance is determined by deriving a coefficient k, utilizing a known reflectance of an object of which reflectance is to be estimated. Thereafter a process of deriving a reflectance at an arbitrary displacement angle is executed for all the wavelengths, for example over a visible wavelength range. In this manner, the reflectance of an object at an arbitrary displacement angle can easily be obtained by utilizing the basic equation for the reflectance derived from the eigenvector obtained from the principal component analysis of the measured data.
