Abstract
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.
Claims6
A scanner device comprising:
- a scanner unit that scans a symbol and obtains image data;
- a judgment unit that judges whether a capture distance from the scanner unit to the symbol is a short distance or a long distance;
- and
- a decoding unit that:
- (i) in a case where the capture distance is judged to be the short distance, makes a setting so as to perform:
- (a) an increase of error permissivity for the image data with respect to threshold values for judging a size of the symbol, or
- (b) a reduction of a number of collation times for decoding results of the image data, and
- (ii) in a case where the capture distance is judged to be the long distance, makes a setting so as to perform:
- (a) a lowering of the error permissivity for the image data with respect to the threshold values, or
- (b) an increase of the number of collation times;
- wherein the decoding unit then decodes the image data in response to the setting.
A non-transitory computer-readable recording medium having stored thereon a computer program that is readable by a computer for use in a scanner device, the computer program causing the computer to perform functions comprising:
- scanning a symbol and obtaining image data;
- judging whether a capture distance from a scanner unit to the symbol is a short distance or a long distance;
- in a case where the capture distance is judged to be the short distance, making a setting so as to perform:
- (i) an increase of error permissivity for the image data with respect to threshold values for judging a size of the symbol, or (ii) a reduction of a number of collation times for decoding results of the image data;
- in a case where the capture distance is judged to be the long distance, making a setting so as to perform:
- (i) a lowering of the error permissivity for the image data with respect to the threshold values, or (ii) an increase of the number of collation times;
- and
- then decoding the image data in response to the setting.
A scanner device comprising:
- an imaging unit that images a symbol and obtains image data;
- a judgment unit that judges whether a capture distance from the imaging unit to the symbol is a short distance or a long distance;
- and
- a decoding unit that,
- (i) in a case where the capture distance is judged to be the short distance, makes a setting so as to perform:
- (a) an increase of error permissivity for the image data with respect to threshold values for judging a size of the symbol, or
- (b) a reduction of a number of collation times for decoding results of the image data,
- (ii) in a case where the capture distance is judged to be the long distance, makes a setting so as to perform:
- (a) a lowering of the error permissivity for the image data with respect to the threshold values, or
- (b) an increase of the number of collation times;
- wherein the decoding unit then decodes the image data in response to the setting.
