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.

Abstract: There is provided an encoding and decoding method and an information recognition device using the same. A code block includes a center coding region and a peripheral coding region arranged around the center coding region. The encoding and decoding method uses the feature of at least one microdot included in the center coding region as codes. The encoding and decoding method uses the feature of at least one microdot included in the peripheral coding region as codes. The encoding and decoding method uses the relative feature between the center coding region and the peripheral coding region as codes. The information recognition device compares the read feature with pre-stored features to decode information such as position codes, object codes, parameter codes and control codes.
