<p><P>PROBLEM TO BE SOLVED: To reduce a data reading failure when regular reflection occurs in an image including a code. <P>SOLUTION: An imaging part 101 images the code from a recording medium with the data recorded as an optically readable code, and a parameter extracting part 102 extracts a parameter about the luminance of a prescribed area in each area of an image including the imaged code. A regular reflection detecting part 105 detects regular reflection in the each prescribed area corresponding to the image including the code on the basis of the extracted parameter. When regular reflection is detected, it is notified to an operator to urge the operator to correct a scanning method for rescanning. It is possible to prevent the code from being imaged in an inappropriate imaging state so that data reading failure can be suppressed. <P>COPYRIGHT: (C)2003,JPO</p> |
