摘要

PPROBLEM TO BE SOLVED: To estimate the light source information of a light source having unknown light source information. PSOLUTION: A first white paper image obtained by capturing white paper placed under the light source having known light source information using an image capturing device is inputted together with the identification information of the light source (S201), and the light source information of the light source having the known light source information is acquired together with the identification information of the light source (S203). On the basis of the identification information, a table 401 wherein the chromaticity of the first white paper image is associated with the acquired light source information is prepared (S204). Then, a second white paper image obtained by capturing the white paper placed under the light source having the unknown light source information using the image capturing device is inputted (S801), the table 401 is referred to, and the light source information of the light source having the unknown light source information is estimated from the chromaticity of the second white paper image (S803).

要解决的问题：估计具有未知光源信息的光源的光源信息。

解决方案：将通过使用图像捕获装置捕获放置在具有已知光源信息的光源下的白皮书而获得的第一白皮书图像与光源的标识信息以及光源信息一起输入（S201）具有已知光源信息的光源的识别信息与光源的识别信息一起被获取（S203）。基于识别信息，准备表401，在表401中，第一白皮书图像的色度与所获取的光源信息相关联（S204）。然后，输入通过使用图像捕获装置捕获放置在具有未知光源信息的光源下的白皮书而获得的第二白皮书图像（S801），参照表格401，并且该光的光源信息从第二白皮书图像的色度估计具有未知光源信息的光源（S803）。
