Disclosed is a scanner device comprising: a scanner unit that scans a symbol and obtains image data; a judgment unit that judges whether or not a capture distance from the scanner unit to the symbol is a short distance; and a decoding unit that, in a case where the capture distance is judged to be the short distance, makes setting to perform at least one of increase of error permissivity for the image data with respect to threshold values for judging a size of the symbol, and reduction of the number of collation times for decoding results of the image data, in a case where the capture distance is judged to be a long distance, makes setting to perform at least one of lowering of the error permissivity, and increase of the number of collation times; and decodes the image data in response to the setting.
