摘要： A bar code reader (12) performs a double-printing detecting process to determine whether or not a plurality of bar codes are overprinted based on an image containing a bar code read by a scanner (13). The bar code reader (12) determines that the recognition result of the bar code is ineffective information when it is detected by the overprinting detecting process that a plurality of bar codes are overprinted and outputs the recognition result of the bar code to a control portion (10) when it is not detected by the overprinting detecting process that a plurality of bar codes are overprinted.

摘要： A barcode recognition apparatus (1) includes an image interface (11), an image analysis unit (12), an image conversion unit (13), and a bar recognition unit (14). The image interface (11) acquires an image including a barcode captured by a camera (2). The image analysis unit (12) analyzes a characteristic of an input image acquired from the camera (2), and decides an image conversion method for the conversion from the input image into an image for recognition processing on the basis of the analysis result. The image conversion unit (13) converts the input image into an image for recognition processing by the image conversion method decided by the image analysis unit (12). The bar recognition unit (14) performs barcode recognition processing for the image for recognition processing obtained by the image conversion unit (13).

摘要： A search processing section (102) searches information stored in an address database, using a first character series, e.g., a postal code input through an input device (13) as a search key, for a second character series corresponding to an address. A character recognition processing section (104) performs character recognition with respect to a predetermined area in the image, using a character dictionary stored in a character dictionary storage section (103), and generates candidates for a character series including a name or designation, a postal code, an address, etc. A character image selection processing section (105) selects a character series corresponding to the searched second character series from the generated candidates. A character image storage section (106) stores correlation between each of the characters constituting the selected character series and a character image thereof. A character dictionary learning processing section (107) performs a learning process with respect to the character dictionary, based on the stored correlation between each character and the character image thereof.
