Abstract
An object displacement detection method includes capturing n images of an object for obtaining n sets of image dots, where the object corresponds to an iset of image dots in an iimage of the n images; performing (n−1) difference calculations using the n sets of image dots to obtain (n−1) sets of difference image dots, where a jset of difference image dots of the (n−1) sets of difference image dots is generated by performing a jdifference calculation of the (n−1) difference calculations using a (j+1)set of image dots and a jset of image dots of the n sets of the image dots; and determining the object has displaced when a sum of numbers of the (n−1) sets of difference image dots reaches a first threshold.
