Title:
METHOD AND DEVICE FOR GENERATING SPECTRAL IMAGE AND RECORDING MEDIUM
Document Type and Number:
Japanese Patent JP2002279415
Kind Code:
A
Abstract:

To provide a method and device for generating a spectral image and a recording medium, having spectral reflectance distribution held in the nature, even if object in a colorimetric image is converted in color when a spectral image of the object is generated from the object.

A combination of eigenvectors is selected from previously prepared plural combinations of eigenvectors, according to the object in colorimetric image. The weighting coefficient is calculated, such that a colorimetric value provided by a weighting coefficient related to each eigenvector of the selected combination of eigenvectors and each eigenvector of the selected combination of eigenvectors, is approximately the same as that of the object in the colorimetric image. Spectral reflectance distribution of the object is provided, by using the calculated weighting coefficient and the selected combination of eigenvectors, and thereby the spectral image is generated.
