Abstract (in Japanese) (See Japanese page) 
(in English) Color images restoration corrupted by Additive noise have been considered. Natural color images have specialty that the correlation between elements is high. In the case of the median filter processing for noise reduction of impulsive noise, multi channel median filters which are considered the correlation between elements, are proposed. However, in the case of the linear filters for Gaussian noise reduction, it is not considered enough that the restoration methods with consideration of the correlation between elements of color images. In this paper, in order to reduce the Gaussian noise which is added the color signal, we derive the multichannel Weiner filter. The multichannel Weiner filter can consider the correlation between elements of the color image, thus, the good restoration results are obtained by low number of parameters of the filter.
