According to the analysis of the features of the image mixed noise, this paper introduces a new image mixed noise removal algorithm based on measuring of medium truth scale. It uses the distance ratio function to detect the noise pixel and to restore the image. The experimental results demonstrate that the new image mixed noise removal algorithm can do better in smoothing mixed noise and preserving details than the classical ones do in subjective aspect and objective aspect, which will lead to its practicable and effective applications in mixed noise removal and image restoration. \itemrv{~} \itemcc{} \itemut{image mixed noise; measuring of medium truth scale; distance ratio function; noise removal; image restoration} \itemli{doi:10.1007/978-3-642-13208-7\_71} \end
