An encoding and decoding method for a microdot matrix includes the steps of: forming a plurality of microdots by encoding based on Reflected Gray Codes in a data region included in each of a plurality of microdot blocks included in a microdot matrix, wherein the microdots corresponding to lower order bits of the Reflected Gray Codes are formed as the outmost microdots in the data region; scanning the microdot matrix to fetch an image and recognizing a microdot group in the date region of each microdot block in the image; and decoding a corresponded coordinate of the image on the microdot matrix according to the microdot block to which the microdot group containing lower order bits of the Reflected Gray Codes belongs. |
