Problems solved by technology

This method uses the same method as Japanese Patent Application Publication No. 123981 / 1996 to change the color, but there is a disadvantage that a large number of variable-angle spectral reflectance must be calculated in advance to obtain two characteristic parameters

Embodiment Construction

[0060] figure 1 A system configuration diagram showing the present invention. As shown, the basic configuration is a monitor (102) capable of full color display connected to a commonly available computer (101). For obtaining the conversion angle or multi-angle spectral reflectance of base color, measure with actually made coated plate or color paper (105), also can obtain from the server (107) of such wide area network as Internet (108) by network. While displaying the CG (104) of the primary color and displaying the CG (103) capable of producing a changing color in the following order, visually observe and evaluate the appearance of the painted color.

[0061] In this specification, "reflectance" refers to the reflectance (R%) of a certain wavelength λ, "spectral reflectance" refers to the reflectance (R(λ)%) of each wavelength λ, and "multi-angle spectral ratio "Refers to the spectral reflectance of each angle in multiple angles. But "spectral reflectance" also sometimes ...

Abstract

The invention includes steps: using spectrophotometer measures spectral reflectance of original color; converting the measured spectral reflectance obtains converted spectral reflectance of changed color; displaying computer graphics in changed color on monitor.

Description

technical field [0001] The present invention relates to a method and device for generating and displaying transformed colors that use computer graphics to arbitrarily change the color quality of painting and output on the screen as computer graphics. [0002] In this specification, the present invention describes the processing method and device of metallic color, but it is obvious that the present invention is not limited to metallic color, and is also applicable to primary color. Background technique [0003] In recent years, in order to speed up the paint development speed of automobile manufacturers, paint design support tool software using computers in various situations has been developed. For example, in order to improve the appearance effect, there is the following metal coloring, that is: mixing colored pigments and flaky luminous pigments (aluminum flakes, pearl flakes, etc.) in the adhesive, or mixing titanium oxide particles using Rayleigh scattering. Depending ...
