Abstract
In an information code reader, an image is imaged by an imager. An information code contained in the image is quantified depending on light-dark levels thereof (tones, color depths, or luminance levels thereof), thereby providing cell information by this quantification. The obtained cell information is transmitted to from the information code reader to a server. In the server, based on the cell information received from the reader, the information code imaged by the imager is decoded. Decoded information is transmitted to the information code reader so that the reader is perform control based on the decoded results.
Claims12
An information code reading system provided with an information code reader and a server which are communicable to each other, an information code being read by the information code reader and being configured to have a plurality of types of cells arranged, tones, depths, or luminance levels of the cells being different between the types,
- the information code reader comprising:
- imaging means for imaging the information code;
- cell information generating means for generating cell information by quantifying the cells of the information code contained in an image imaged by the imaging means, depending on the tones, depths, or luminance levels;
- and
- transmitting means for transmitting to the server the cell information generated by the cell information generating means, and
- the server comprising:
- decoding means for decoding the information code imaged by the imaging means, based on the cell information received from the information code reader;
- and
- server-side controlling means for performing control based on results decoded by the decoding means.
An information code reader, the reader optically reading an information code in which a plurality of types of cells are arranged, the cells having tones, depths, or luminance levels which are different between the types, the reader comprising:
- imaging means for imaging the information code;
- cell information generating means for generating cell information by quantifying the cells of the information code contained in an image imaged by the imaging means, depending on the tones, color depths, or luminance levels;
- transmitting means for transmitting to a server the cell information generated by the cell information generating means, the server having a decoding function;
- and
- reader-side controlling means for performing control based on information received from the server in response to transmitting the cell information.
