<p>PURPOSE: To efficiently process images encoded through various methods, to convert these images into alphanumeral data, and to store them. CONSTITUTION: Information is extracted from a document containing a 1st symbol detectable in a 1st scanning mode to use light in a 1st spectrum area, but undetectable in a 2nd scanning mode to use outside the 1st spectrum area, and a 2nd symbol detectable in the 1st or 2nd scanning mode. Concerning document data expressing information for which the 2nd symbol is encoded by formats more than one detectable by automatic symbol recognition resources, object areas more than one are defined and scanned in the 2nd scanning mode and as a result, pixel data are stored in a storage device. Besides, one object area is selected out of the defined areas, the picture element image in the relevant object area is processed by the automatic symbol recognition resources suitable for the encoded format designated for the 2nd symbol, and output records more than one related with symbol information expressing the 2nd symbol are generated.</p> |
