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.
Claims24
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;
- wherein a decoding direction of the code region is not relative to the boundary region;
- wherein 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.
A barcode processing system, comprising:
- an image sensor, configured to optically sense a sensed image;
- and
- a processing circuit, configured to determine if a closed shape object exists in the sensed image, to identify a code region within the closed shape object in the sensed image, wherein the code region comprises bright points and dark points, wherein the processing circuit generates code information according to at least one of:
- a color sequence, an intensity sequence and a relation between the bright point and the dark point;
- wherein a decoding direction of the code region is not relative to the closed shape object.
A coffee machine, comprising:
- a capsule container, configured to hold a capsule;
- a liquid injection probe;
- a barcode reader, comprising:
- an image sensor, configured to optically sense a sensed image;
- and
- a processing circuit, configured to determine if a closed shape object exists in the sensed image, to identify a code region within the closed shape object in the sensed image, wherein the code region comprises bright points and dark points, herein the processing circuit generates code information according to at least one of:
- a color sequence, an intensity sequence and a relation between the bright point and the dark point;
- wherein a decoding direction of the code region is not relative to the closed shape object;
- wherein a plurality of barcodes respectively comprising the closed shape object and the code region repeats around a top surface of the capsule;
- wherein the liquid injection probe and the barcode reader faces the top surface, and a distance between the barcode reader and the top surface allows the barcode reader to read at least one complete barcode.
