PROBLEM TO BE SOLVED: To achieve accurate synthesis processing by applying correction processing to image data when reading a bar code from a reference position before synthesizing the image data of the bar code.SOLUTION: A bar-code reading apparatus 1 reads a bar code more than once by a reading part 15, acquires bar code image data upon every reading, stores each of the acquired bar code image data in a RAM 14, and detects a moving state of the reading part 15 in 3 dimensional space during reading operation of the bar code by a gyro sensor 16. A CPU 10 corrects each of the bar code image data stored in the RAM 14 into the bar code image data in the case that the bar code image data is read from a predetermined reference position on the basis of the moving state detected by the gyro sensor 16, synthesizes each of the corrected bar code image data, and decodes the synthesized bar code image data. |
