  • Patent number: 7818652
    Abstract: An object of the present invention is to provide an image forming system, an image processing apparatus, a determination device, and image processing method that are capable of preventing users' convenience from reducing even when an image forming apparatus prints a coded image with a low print precision. A first MFP is connected through a LAN to a second MFP for performing error-correcting coding of original information, for creating a coded image by imaging the original information with the error-correcting code, and for forming the created coded image on a sheet. The first MFP extracts the original information from the coded image on the sheet obtained by reading the sheet on which the coded image is formed. Thereafter, the first MFP transmits to the second MFP an error detection rate at the time when the original information is extracted.
