OPTICAL INFORMATION READING DEVICE, OPTICAL INFORMATION READING METHOD, OPTICAL INFORMATION READING PROGRAM, AND RECORDING MEDIUM

PROBLEM TO BE SOLVED: To fetch bar code information from a remote place by using a Hidden Markov Model (HMM). SOLUTION: An input image photographed by an input device (CCD 103) is stored in an input image buffer 171 of a memory 107 installed on a decode substrate 106. Data stored in an input image b...

description	PROBLEM TO BE SOLVED: To fetch bar code information from a remote place by using a Hidden Markov Model (HMM). SOLUTION: An input image photographed by an input device (CCD 103) is stored in an input image buffer 171 of a memory 107 installed on a decode substrate 106. Data stored in an input image buffer 171, an extraction bar code image buffer 172, an extraction featured value buffer 173, and a read-in buffer 174 of the memory 107 are supplied to a bar code region extraction part 151, a featured value extraction part 152, and HMM decode part 153 of a CPU part 105. Then, decoded characters are stored in a bar code reading result buffer 175 of the memory 107, and fetched to an output device 109. COPYRIGHT: (C)2009,JPO&INPIT
