A first mixer receives, as a first IF input signal, a digital signal obtained by sampling a received signal with an RF signal or an IF signal, and converts the first IF input signal to a second IF signal using the first local oscillator. A digital filter suppresses an outband signal of the second IF signal provided from the first mixer. A second mixer converts an output of the digital filter to a detection process frequency using the second local oscillator. An available frequency step of the first local oscillator is larger than an available frequency step of the second local oscillator.

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.
