Abstract
A symbol information reader may include an imager; an image memory configured to save image data of a recording medium; and a position detecting processor configured to retrieve the image data and detect the positions of symbols on the recording medium. The position detecting processor may be configured to calculate the amount of change in luminance value of scanning lines in a predetermined area of the image data and discriminate a provisional area possibly corresponding to the symbol, acquire correlations of the provisional area with neighboring areas and create a map showing an area with high correlation values, search the correlation map for the presence of the symbols and label on areas judged having the symbols, set an area for each of the multiple symbols and makes divisions, and detect positions of the symbols printed on the recording medium.
