Then the principle and machinery of them are discussed . the fourth step , the experiments of the enhancement ratio of 1 . 5 , 2 and 2 . 5 are carried out . the method of inversion analysis is used for ft ccd and the method of simple pixel cross - interpolation is used for it ccd 對(duì)于行轉(zhuǎn)移ccd ,針對(duì)其盲區(qū)較大的特點(diǎn),可以設(shè)計(jì)較簡(jiǎn)單的象素交叉插值,利用兩幅位移為0 . 5象素的原圖,獲得分辨率提高2倍的高分辨率圖。
