Abstract
A color conversion method is provided wherein, in a case where color signals outputted by a sensor such as a CCD are to be converted into signals expressive of predetermined colors prescribed in a predetermined color space, a conversion matrix is calculated by a multiple linear regression analysis in consideration of elements based on noise developed by the CCD or the like or on the change of an illuminating light source, and the output signals of the CCD or the like are converted using an obtained conversion matrix.
