    摘要： The present invention aims at restoring backup data in a predetermined order and avoiding damage from being given to the system even when the backup data are destroyed. Flags Ferr and Feeprom and a variable i stored in a DRAM are initialized (S1 to S3). When the variable i is smaller than the number n of EEPROMs (hereinafter referred to as “PROM(s)”), the ID code of a PROM in question is read and loaded into the DRAM (S4 to S6). When the variable i equals the number n, the variable i is cleared (S7). Then, a variable j is initialized (S9), and it is determined whether or not each PROM ID stored in the DRAM matches with a mask ROM ID until the variable j becomes greater than the number n of PROMs (S11). If the answer is “No”, the variable j is incremented (S13), while if “Yes,” a number corresponding to the variable j then assumed is loaded into the DRAM as the flag Feeprom (S14). Data in the PROM in question is transferred to an area of the DRAM in which is stored the PROM ID matching with the mask ROM ID.

    摘要： A method and apparatus for recognizing character information in an original document with high recognition accuracy regardless of the size of a character to be recognized. An input image is processed by an image processing circuit and stored in an image recording unit. A character region in the recorded image data is detected by a recognition section, and the image corresponding to the detected character region is read with a predetermined magnification. Character recognition is performed on the image of the character region read at the predetermined magnification, in the recognition section. If the recognition accuracy does not satisfy a predetermined criterion, the same image is read again with a modified magnification wherein the magnification is determined on the basis of preset sizes and the size of the character pattern of a character to be recognized. The image obtained in this way is subjected again to character recognition processing until the recognition accuracy satisfies the predetermined criterion. A character pattern corresponding to the recognized character is generated, and recorded together with the image recorded in the image recording unit in an image recording section. Thus, an image is read with a magnification optimized depending on a character size of an original document image and on a recognition accuracy.
