Abstract:
A code image quality check apparatus adapted to check a quality of a code image printed and recorded on a printing medium as an optically readable image of error correcting code data containing information data including at least one of audio information, video information and digital data and adapted to be optically read by a manual scanning operation,said error correcting code data being provided with an ability to correct code image read errors attributable at least to one of the quality of the code image, a performance of the code image reader and undefinable reading conditions resulting from the manual scanning operation, andsaid code image quality check apparatus comprising:read means for picking up and optically reading said code image;restoration means for restoring the error correcting code data from the code image read by said read means;read error extraction means for extracting the code image read errors from the error correcting code data restored by said restoration means, without processing the restored error correcting code data to actually correct the code image read errors;counter means for reducing the code image read errors extracted by said read error extraction means into numerical values, and for counting the code image read errors; andnotification means for indicating the numerical values obtained by the counter means in a predetermined mode of notification.
