Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we use tools from Riemann geometry to show a color-weak correction method that takes into account individual color perception properties of observers.
We measured the discrimination thresholds for color-normal observers and a color-weak observer and construct an isometry between the color spaces of both observers using Riemann normal coordinates.
The proposed method is first applied on chromaticity plane. Then we try to correct also brightness besides the chromaticity in order to achieve 3D correction on the two color spaces.
Effect of the proposed method is confirmed by SD method and Principle Component Analysis.
