In order to restore these images, we need to estimate PSF (Point Spread Function) from them. It has been proposed to estimate PSF using cepstrum images. There are PSF features in the cepstrum images of blurred images. We can estimate PSF by searching pixels in the cepstrum images. However cepstrum images also show features of ground-truth images, so we can't estimate the PSF accurately. We propose estimation method of PSF by using GA. We adopt the cepstrum images as a fitness function, thus the estimation results aren't affected by other features in cepstrum images. We have just confirmed the effectiveness of our proposed method by using some simulations.本誌: 電気学会論文誌C（電子・情報・システム部門誌） Vol.132 No.7 （2012） 特集：平成23年電気学会電子・情報・システム部門大会本誌掲載ページ: 1101-1107 p原稿種別: 論文／日本語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejeiss/132/7/132_1101/_article/-char/ja/
