Abstract
A barcode, comprising: a code region, comprising at least bright point and a dark point, comprising code information; and a boundary region, formed as a closed shape surrounding the code region. A decoding direction of the code region is not relative to the boundary region. The code information is represented by at least one of: a color sequence, an intensity sequence and a relation between the bright point and the dark point. The present invention also provides a barcode processing system which can process the barcode to generate a control command, and provides a coffee machine using the barcode processing system. The barcode can be easily aligned by a closed boundary region, without using a frame buffer with a large size.
