发明名称 Preamble data generating method and related apparatus for quick response code
摘要 In order to increase the preamble information capacity of the QR code and avoid decoding errors, a method of embedding preamble information into a standard quick response (QR) code symbol is provided to generate a first QR code symbol. The method includes generating a preamble pattern according to a user definable data; and embedding the preamble pattern into a standard position detection pattern of the standard QR code symbol to generate a first position detection pattern.
