    This invention relates to a method for reparing moldy spot noises in cinefilms with an adaptive smooth reparing model including a moldy test and filling up, in which, said test includes movement sphere estimation, a movement test and a noise judgement, first of all, a movement test process mode of the current frame is judged by the estimation of the movement sphere, a two-way matchness algorithm is applied for the movement test, after that, Weber ratio and noise property are used to judge the noise points of the current frame and generate a noise mark chart and a background color picture, said moldy spot filling-up includes: utilizing an expansion algorithm to process the noise mark chart to overcome the noise edge problem when marking noises then reparing the current frame based on the expanded mark chart and the background color picture.
