Repeatedly sampling method for image scanning

Abstract

The present invention provides a repeatedly sampling method for image scanning. It is mainly a sample treatment procedure proceeded for the data of an image scanning device during the scanning of an image. The method mainly includes the steps of sampling, sorting, eliminating group-departing value, and getting mean value, etc. Wherein, the sampling procedure makes several times of scanning pick-up on a single point of the image to produce several sets of sampling value; the sorting procedure sorts the several sets of sampling value after being sampled according to their magnitudes; the eliminating group-departing value procedure gives up the relatively larger values and relatively smaller values from the several sets of sampling value after being sorted; the getting mean value procedure gets a mean value from the several sets of sampling value. By applying the repeatedly sampling method of entirety of the invention, it may reduce the error of data pick-up during the procedure of scanning.
