A processing method of detecting a barcode from an original image includes: an edge processing process, a barcode positioning process and a projection modification process. The edge processing process is for converting an original image into a binarized input image. The barcode positioning process is for deriving position information of the barcode, and includes: deriving a plurality of luminance groups according to luminance values of all pixels of the input image; utilizing a determining circuit to determine whether each luminance group complies with an identification bar and to derive position information of the identification bars; and deriving position information of the barcode according to the position information of the identification bars. The projection modification process converts the original image into a modified image according to the position information of the barcode.
