Abstract: An object driving device includes an object, a driving unit, an image capturing unit and a processing unit. The driving unit is connected to the object. The processing unit is electrically connected to the driving unit and the image capturing unit. The processing unit controls the driving unit to drive the object to move and controls the image capturing unit to capture a plurality of initial images. The processing unit subtracts pixel data of every two adjacent initial images from each other to obtain at least one subtracted image. The processing unit determines a current image position of the object in each of the at least one subtracted image. The processing unit determines a current real position of the object according to the current image position. The processing unit controls the driving unit to drive the object to move from the current real position to a target position.

Abstract: A barcode identification method includes generating a binarization barcode by using a binarization process from a sampled barcode, acquiring a first region from the binarization barcode, acquiring a first narrow element width from the first region, acquiring a second region from the binarization barcode, acquiring a second narrow element width from the second region, generating an extension region by extending the second region when the second narrow element width is smaller than the first narrow element width, generating a plurality of binarization sequences corresponding to the extension region, decoding at least one of the binarization sequences for generating at least one decoded sequence by using a lookup table, and verifying the at least one decoded sequence for generating a verified sequence by using a checksum code.

Abstract: A barcode decoding method includes steps of (a) capturing an image of a barcode; (b) analyzing the image to recognize a data region of the barcode; (c) decoding the data region to obtain a codeword matrix, wherein the codeword matrix includes a plurality of codewords; (d) performing an error correction for the codeword matrix; (e) when the codeword matrix fails to pass the error correction, repeating steps (a) to (c), updating the codeword matrix according to a number of occurrence times of each codeword at an identical position of the codeword matrix, and repeating step (d) for the codeword matrix after updating; and (f) when the codeword matrix passes the error correction, decoding the codeword matrix.
