ABSTRACT:
The present disclosure provides a repeated sampling method for image scanning. In one or more embodiments, the sampling method may comprise a sample treatment procedure for the data of an image scanning device during the scanning of an image. The method may comprise sampling, sorting, eliminating one or more group-departing values, and getting a mean value, etc. The sampling procedure may involve scanning a single point of the image several times to produce several sets of sampling values. The sorting procedure may involve sorting the several sets of sampling values after being sampled according to their magnitude. The eliminating group-departing values procedure may involve obtaining the relatively larger values and relatively smaller values from the several sets of sampling values after being sorted. The getting mean value procedure may involve obtaining a mean value from the several sets of sampling values. By applying the repeated sampling method the error of data pick-up during the procedure of scanning may be reduced.
